Description

Cell operation method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a cell operation method and apparatus.

Background

In an LTE (long term evolution) system, nodes on the network side are often connected by wires, and as shown in fig. 1, base stations eNB are connected by wires, and the base stations eNB and core network nodes, such as a mobility management unit MME and a serving gateway SGW, are also connected by wires.

Operation of the existing cell:

the existing cell is defined as: set of downlink resources and possible uplink resources. The association of the downlink resource carrier frequency and the uplink resource carrier frequency is indicated by a system message transmitted on the downlink resource. The carrier frequency refers to the center frequency of the cell. Different carriers form different cells, and the carriers can provide service for users together in a Carrier Aggregation (CA) mode.

Cell is a network device that is on the same carrier frequency for a terminal and provides services to the terminal. Currently the maximum bandwidth of a single carrier is 20 MHz.

In the future development of the mobile communication system, in order to better meet the user requirements and greatly improve the network capacity and throughput, more transmission nodes are inevitably introduced, i.e. the mobile communication system is an ultra-dense network in the future. In a super-dense network, if each frequency point of each original transmission node is also used as a cell among mass transmission nodes, great challenges are brought to the management and overhead of the cells.

In the prior art, the bandwidth of an operating carrier of a single cell is maximally defined as 20MHz, and the operating carrier does not support the operation as a cell when non-ideal backhaul connection is formed among a plurality of nodes. Under such a limitation, if 5G is used in the future, the terminal needs to provide services with a bandwidth greater than 20MHz and to move smoothly among a plurality of transmission nodes, which cannot be well supported by the current technology. Switching can be performed only between a plurality of physical nodes, and a large bandwidth is cut into a small bandwidth, for example, one carrier of 20MHz, and multi-carrier aggregation is performed, where each carrier has respective common signaling overhead and management overhead. The consequences are poor user experience and low network side efficiency.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

First embodiment

The core idea of the first embodiment of the present invention is as follows: for an idle state terminal, the terminal resides in a unified residence layer, wherein the residence layer is perceived by the terminal by sending common messages such as system messages and synchronization signals synchronously by a plurality of network nodes. A terminal may initiate an access procedure at a dwell layer or at a designated time-frequency domain location, and after entering a connected state, the terminal may be configured with dedicated transmission resources provided by different network nodes on the same or different frequency bands.

The resident layer is the sum of resources that the terminal can perceive when it is resident in an idle state. The resource sets that the terminal can see in the residing state and the connection state are different, the resources that the residing state needs to monitor are collectively called as the residing layer, and after the terminal enters the connection state, the transmission resources used by the terminal can be configured, and a larger extension exists outside the residing layer.

As shown in fig. 2, a first embodiment of the present invention provides a cell operation method, applied to a terminal side, including:

step 21, receiving the same synchronization signal sent by a plurality of first network nodes in a first frequency band resource of a first cell to which the plurality of first network nodes belong, and acquiring downlink timing synchronization with the plurality of first network nodes according to the same synchronization signal; in short, for an idle terminal, the terminal is powered on, performs cell initial search and synchronization signal acquisition, and acquires downlink synchronization timing.

Step 22, receiving the same first system message synchronously sent by each first network node, and camping on the first cells to which the plurality of first network nodes belong according to the same first system message.

In this step, the step of receiving the first system message specifically includes: the terminal obtains the time-frequency domain position for receiving the first system message according to a pre-configured or standard specified mode (such as a broadcasting mode), and reads the first system message from the time-frequency domain position. The first system messages sent by the plurality of first network nodes in the first embodiment of the present invention are also the same. Wherein the same first system message comprises: full band resources (frequency point bandwidth) of the first cell, access parameters of the first cell, and camping and cell selection information of the first cell. And the terminal selects to camp on the first cell according to the camping and cell selection information in the first system message.

In the first embodiment of the present invention, a plurality of first network nodes transmit the same synchronization signal, so for the terminal, the terminal in an idle state does not need to distinguish the network nodes, and is equivalent to residing in a large area with a large coverage area. The large cell refers to a first cell to which a plurality of first network nodes belong.

It should be noted that, since the plurality of network nodes send the same synchronization signal, in order to save bandwidth overhead of the synchronization signal, the plurality of first network nodes all send in the preset first frequency band resource; that is, the plurality of first network nodes transmit the same synchronization signal using the same first frequency band resource;

specifically, the first frequency band resource is a preset narrow-bandwidth position in the full frequency band resource of the first cell, for example, a central narrow bandwidth of the full frequency band resource of the first cell; or,

the first frequency band resource is a plurality of preset time-frequency domain positions in the full frequency band resource of the first cell, for example, the first frequency band resource spans the full frequency band resource of the first cell, but only appears in a part of the time-frequency domain; again, for example, the first frequency band resource spans a portion of the frequency band resource of the first cell, but also only occurs in a portion of the time-frequency domain.

It should be noted that, no matter the first frequency band resource is at a preset narrow-wideband position or at a plurality of preset time-frequency domain positions, for a connected terminal, the resource range available for data transmission is wider than that of the prior art.

After the terminal successfully camps on the first cell and obtains the basic parameters of access from the first system message, if the terminal has a need for data transmission, etc. to perform a connected state, in the first embodiment of the present invention, after step 22, the cell operation method further includes:

step 23, accessing at least one first network node according to the same first system message; after the terminal accesses at least one first network node, the terminal enters a connected state from an idle state.

Step 24, receiving a second frequency band resource configured for the terminal by at least one first network node to which the terminal successfully accesses, and performing data transmission with the first network node through the second frequency band resource; the second frequency band resource is all or part of the remaining frequency band resources obtained by removing the first frequency band resource from the full frequency band resources of the first cell.

After the terminal enters the connected state, the network side needs to configure the terminal with the optimal transmission resource, i.e., the second frequency band resource. The second frequency band resource is provided by a different first network node on the same or a different frequency band. It should be noted that the remaining frequency band resources are reusable transmission resources, that is, the same frequency band resource can be reused by different terminals, where it is necessary to avoid interference between different terminals. Specifically, in the first embodiment of the present invention, step 23 includes:

step 231, accessing at least one first network node according to the access parameter of the first cell in the first system message; the access parameter includes access code configuration information and/or access resource configuration information.

Further, step 231 includes:

step 2311, determining an access code and/or access resource of the terminal according to the access code configuration information and/or access resource configuration information;

step 2312, transmitting the access code to at least one first network node or transmitting data information to at least one first network node on the access resource;

step 2313, receiving the identification information and uplink transmission resource allocated by the first network node to the terminal, which are returned by the at least one first network node, and the terminal successfully accesses the at least one first network node.

Specifically, in the above embodiment of the present invention, the step of the terminal initiating the access process to the network is as follows:

in the preparation phase, the terminal needs to acquire downlink synchronization (cell-level synchronization or network node-level synchronization) with the network first, and obtain basic access parameters, such as access code configuration, access resource configuration, and configuration of access transmission parameters such as power, from the broadcasted system information.

And in the initiating stage, when the terminal needs to enter a connection state, for example, the terminal has data to transmit, the terminal selects a proper access code and an appropriate access resource according to the configuration parameters.

The access resource may be from the camping layer or from a resource other than the camping layer. As for the resources of the resident layer, the resources can be generally used by the terminal with weaker capability; for the resources outside the resident layer, the resource space is larger, and the requirement on the terminal capability is also high, so that the terminal with stronger capability can generally use the resources.

Specifically, the access codes and the access resources may be classified according to the configuration of the network side, for example, the terminals meeting the condition a use the access codes in the group a and a group of access resources; the terminals meeting the condition B use the access code in the group B and the access resource of another group, and in each group, in order to avoid collision between two terminals, the access code and the access resource in the group are generally selected in a random manner.

In addition, the access code bound with each terminal can be designed, so that the terminal can directly use the access code of the terminal, and collision is avoided. But generally the access resources are still contention and the selection of access resources is also in the above manner, i.e. grouped, re-randomized within the group, or directly randomized.

The terminal can initiate the sending of the uplink access code; or,

the terminal can also directly initiate the transmission of small data on the uplink competitive access resources, for example, directly send the radio resource control RRC connection establishment request message and/or the uplink sending buffer information; specifically, the contention access resource may be fixedly and periodically allocated, for example, in a broadcast message, time-frequency domain location information of the contention access resource is configured, or dynamically scheduled, for example, in a broadcast message, time-frequency domain information of the contention access resource is configured, and at a predetermined time each time, the location of the frequency domain resource is determined in a dynamic scheduling manner, and an identifier used in the dynamic scheduling is a contention resource identifier common to a plurality of terminals.

The terminal receives feedback information from the network node within a certain receiving interval, such as a receiving window:

if the terminal sends the access code, the network side feeds back the specific identification information of the terminal and the uplink transmission resource information for the transmission of the subsequent uplink data of the terminal.

If the terminal sends data, the network side can feed back the terminal-specific identification information and corresponding signaling (for example, RRC connection establishment) or uplink transmission resource grant according to the data content.

Subsequently, the terminal uses the identification information to communicate with the network side, optionally performs contention resolution, establishes an RRC connection, and enters a connected state.

Further, after the terminal completes the initial access and before receiving the second frequency band resource, i.e. between step 23 and step 24, the cell operation method further includes:

step 25, reporting the capability information of the terminal to the first network node which is successfully accessed; that is, after the initial access is completed and the terminal enters the connection state, the terminal reports the capability information of the terminal to the first network node, wherein the capability information comprises the supported receiving frequency band and the receiving frequency band combination information.

Step 26, receiving a configuration signaling generated by the first network node according to the capability information and the preliminary measurement result of the terminal, and measuring other network nodes indicated in the configuration signaling according to the configuration signaling; namely, the terminal receives the configuration signaling of the network side, and measures the relevant network nodes according to the configured transmission node set or measurement set.

Step 27, reporting the measurement result to the first network node, so that the first network node can configure the second frequency band resource for the terminal or configure a new network node for the terminal according to the measurement result. The terminal reports the measurement result, if the measurement result is the measurement result of layer three (medium access control layer), the measurement result is reported by RRC signaling, and if the measurement result is the measurement result of layer one (physical layer), the measurement result is reported by a mode of layer one or layer two (RRC layer). After the measurement result is reported to the first network node, receiving a reconfiguration signaling of the configuration set or the measurement set sent by the network side, starting a new set and related operations, receiving a layer-one-layer-two signaling of the rapid service node adjustment sent by the network side, and transmitting the signaling on a new service transmission node.

It should be noted that, for an Inactive terminal (a terminal in an Inactive state), if transmission of a small amount of data is allowed, the transmission may be limited to be performed in the persistent layer, because the Inactive terminal exhibits a characteristic similar to that of an idle terminal on an air interface, and may only perform monitoring processing in the persistent layer, which simplifies complexity. For the contention transmission, the contention transmission can be only carried out in a resident layer or a specific frequency layer of other configurations, so that the process is simple.

In summary, in the first embodiment of the present invention, the first frequency band resource (the camping layer) and the second frequency band resource (the transmission resource) are distinguished on the full frequency band resource of the first cell; for a terminal in an idle state, residing on a residing layer, and acquiring system messages, synchronization signals and the like; the network nodes need to transmit system messages synchronously and simultaneously among a plurality of network nodes; the terminal can initiate an access process on the resident layer or an access resource outside the resident layer; after the terminal enters a connection state, one or more transmission nodes provide data transmission service on the same frequency band or different frequency bands for the terminal; the data transmission resources can be multiplexed in the frequency band range of the whole cell, except resident layer resources which already transmit system messages and synchronous signals, the overhead of common signaling is reduced, the system efficiency is improved, and good user experience is guaranteed.

Second embodiment

The second embodiment of the present invention is consistent with the core idea of the first embodiment described above, and will not be described repeatedly herein. As shown in fig. 3, a second embodiment of the present invention provides a cell operation method, applied to a network side, including:

step 31, the plurality of first network nodes send the same synchronization signal in the first frequency band resource of the first cell to which the plurality of first network nodes belong, so that the terminal can obtain downlink timing synchronization with the plurality of first network nodes according to the same synchronization signal;

and step 32, the plurality of first network nodes synchronously send the same first system message, so that the terminal can camp on the first cells to which the plurality of first network nodes belong according to the first system message. Specifically, the same first system message includes: full band resources of the first cell, access parameters of the first cell, and camping and cell selection information of the first cell.

For the network side, the network side of the centralized architecture is exemplified in the second embodiment of the present invention, the network nodes in the centralized architecture are divided into transmission nodes and centralized nodes, and the centralized nodes are located at the control layer of the network side and can control a plurality of transmission nodes. To implement the above-described camping procedure of the UE, the following operations are roughly required:

firstly, a network side needs to plan which transmission nodes can belong to the same cell, bandwidth and central frequency point of the cell, and common signaling (such as synchronous signals and system messages) are sent on which resources, plan a centralized node of the cell, and inform the transmission nodes of a mode of centralized node pre-configuration or software downloading.

Generally, the operating frequency range of a cell is relatively wide, for example, the bandwidth is between 100MHz and 2GHz, but the broadcast system messages may not be transmitted at the full bandwidth, may be transmitted in a partial frequency range thereof, for example, at the central 20MHz, or may be transmitted over several small frequency bands. Of course, the broadcast may also be sent across the entire cell bandwidth, depending on the network deployment plan, how it is done.

After the transmission node is started, the transmission node is contacted with a centralized node area of the transmission node and establishes related connection; the transmitting node may report its capabilities and/or measurements to the centralized node for better configuration by the centralized node; the capabilities of the transmission node include radio frequency capabilities of the transmission node, such as which bandwidths are supported, receiver conditions, etc., and may also include processing capabilities; the measurement result may be a measurement result of the operating frequency and interference of the transmission node to its surrounding transmission nodes, and the like.

The centralized node sends the configuration of the transmission node, wherein the configuration can be generated by the centralized node according to an OAM (operation, maintenance and management) planning range and an algorithm thereof, or can be forwarded by the centralized node after the OAM is directly configured; the configuration may include the working frequency point and bandwidth combination of the transmission node, the protocol stack configuration, whether the transmission node participates in system message/synchronization signal transmission, etc.

If the transmission node participates in the transmission of the system message/synchronization signal, the centralized node needs to inform the transmission power-saving transmission content and the synchronous transmission mode so that the transmission node can synchronously transmit the information together with other transmission nodes; if the transmitting node does not participate in the transmission of the system message/synchronization signal, the transmitting node waits for terminal access.

It should be noted that, for a terminal in idle state (idle state) or inactive state (inactive state), mobility procedures such as cell selection and reselection may be performed based on the signal measurement result of the camping layer. The sending of the paging information can also be only carried out in the resident layer, thus simplifying the processing complexity of the terminal.

After the terminal successfully camps on the first cell and obtains the basic parameters of access from the first system message, if the terminal has a need for data transmission, etc. to perform a connected state, then in the first embodiment of the present invention, after step 32, the cell operation method further includes:

step 33, receiving an access code sent by the terminal or data information sent on an access resource of the terminal;

and step 34, allocating identification information and uplink transmission resources to the terminal according to the access code or the data information, and determining that the terminal is successfully accessed to the first network node.

Specifically, from the perspective of the network side, the network side needs to send the configuration required by the terminal access to the terminal in a broadcast manner; the transmission node receives the access code or data information sent by the terminal on the uplink competition resource, and replies according to different conditions:

if the access code is the access code, optionally allocating specific identification information to the terminal, allocating uplink resources and sending the uplink resources to the terminal;

if the signaling is the RRC connection establishment request signaling, optionally allocating specific identification information to the terminal, responding to the signaling, for example, generating the RRC connection establishment signaling, and sending the RRC connection establishment signaling to the terminal;

if the information is other information, such as uplink buffer information, specific identification information is optionally allocated to the terminal, uplink resources are allocated according to the buffer size, and the uplink resources are sent to the terminal.

The subsequent network side performs contention resolution on the terminal according to the requirement, that is, the identity of the terminal which is successfully accessed at this time needs to be sent back, the successful terminal continues to perform the subsequent process, and the failed terminal initiates the access process again.

Step 35, configuring a second frequency band resource for a terminal which is successfully accessed, and performing data transmission with the terminal through the second frequency band resource; the second frequency band resource is all or part of the remaining frequency band resources obtained by removing the first frequency band resource from the full frequency band resources of the first cell.

After the terminal enters the connected state, the network side needs to configure the terminal with the optimal transmission resource, i.e., the second frequency band resource. The second frequency band resource is provided by a different first network node on the same or a different frequency band. It should be noted that the remaining frequency band resources are reusable transmission resources, that is, the same frequency band resource can be reused by different terminals, where it is necessary to avoid interference between different terminals.

Further, step 35 in the second embodiment of the present invention includes:

351, performing preliminary measurement on the successfully accessed terminal, and acquiring the capability information of the successfully accessed terminal;

step 352, generating a configuration signaling for the terminal according to the preliminary measurement result and the capability information, and sending the configuration signaling to the terminal, where the configuration signaling is used to instruct the terminal to measure other network nodes;

step 353, obtaining a measurement result of the terminal, and configuring a second frequency band resource for the terminal or configuring a new network node for the terminal according to the measurement result.

Specifically, in the above embodiment of the present invention, the terminal initiates the access process to the network, and from the network side, the steps are as follows:

finishing the initial access of the terminal, establishing RRC connection, and performing initial measurement on the terminal in the initial access process; capability information of the terminal is collected, including supported reception bands and reception band combination information.

The network side can preliminarily determine which transmission nodes the terminal is located near according to the measurement when the terminal initially accesses, so that the reference signal information of the transmission nodes is configured to the terminal, and the terminal can conveniently measure the adjacent transmission nodes, wherein the measurement configuration can include the measurement of a specific transmission node and the measurement of a reference signal on a specific frequency band; in addition, the network side may also determine a configuration set of the terminal, that is, a transmission node satisfying a certain signal reception threshold or a certain amount of peripheral nodes according to algorithm needs, and configure the configuration set to the terminal as a most basic configuration set of the terminal, where at least the configuration set should include how the terminal monitors the scheduling signaling.

Each transmission node may operate in a different frequency band or may operate in the same frequency band. For the camping band, dedicated transmission of each transmission node may be scheduled on a resource that does not transmit common information.

Secondly, collecting a measurement result of the terminal; in addition, the measurement of the terminal configuration may include measurement of layer three or measurement of layer one, where the measurement result of layer three is an average of measurement results within a certain time to determine whether a certain transmission node is suitable as a configuration set or an alternative serving node of the terminal, and the measurement result of layer three is generally sent in an RRC signaling manner; the measurement result of layer one is generally transmitted in a layer one or layer two manner for monitoring the more dynamic link quality, so as to select the real-time transmission parameters and transmission nodes of the terminal.

According to the measurement result, the network side can accurately adjust/reconfigure the configuration set/measurement set and the service node of the terminal; for example, when a certain transmission node is gradually far away from the terminal according to the movement of the terminal and the signal quality is gradually reduced, the transmission node may be moved out of the configuration set or the measurement set of the terminal, and the terminal moves toward a new transmission node according to the movement of the terminal and the deployment of the transmission node, the new transmission node may be added into the configuration set or the measurement set of the terminal; in addition, when adding, the frequency point receiving capability of the terminal needs to be considered, a transmission node of which the working frequency band is within the receiving capability range of the terminal needs to be added, or the working frequency band of the transmission node is adjusted according to the receiving range of the terminal. For dynamic selection of a service node, an optimal transmission node is generally selected from a configuration set of a terminal, and is quickly sent to the terminal in a layer-by-layer signaling manner.

In summary, a second embodiment of the present invention is a cell operation method on a network side corresponding to the cell operation method of the terminal in the first embodiment, and distinguishes a first frequency band resource (a camped layer) and a second frequency band resource (a transmission resource) on a full frequency band resource of a first cell; for a terminal in an idle state, residing on a residing layer, and acquiring system messages, synchronization signals and the like; the network nodes need to transmit system messages synchronously and simultaneously among a plurality of network nodes; the terminal can initiate an access process on the resident layer or an access resource outside the resident layer; after the terminal enters a connection state, one or more transmission nodes provide data transmission service on the same frequency band or different frequency bands for the terminal; the data transmission resources can be multiplexed in the frequency band range of the whole cell, except resident layer resources which already transmit system messages and synchronous signals, the overhead of common signaling is reduced, the system efficiency is improved, and good user experience is guaranteed.

Third embodiment

The core idea of the third embodiment of the present invention is as follows: for the idle terminal, different synchronization signals sent by different network nodes are received, but the received system messages sent by the different network nodes are the same, the terminal can judge which network nodes belong to the same cell according to the same system messages sent by the different network nodes, then the cell is resided according to the cell selection principle, the subsequent access and transmission process is the same as that of the first embodiment, and the description is not repeated again,

as shown in fig. 4, a third embodiment of the present invention provides a cell operation method, applied to a terminal side, including:

step 41, receiving different synchronization signals sent by a plurality of second network nodes in the third frequency band resource of the second cell to which the plurality of second network nodes belong, and respectively obtaining the downlink timing synchronization with at least one second network node according to the different synchronization signals.

In this step, for the idle terminal, the terminal is turned on, performs initial cell search and synchronization signal acquisition, and the terminal and at least one second network node acquire downlink synchronization timing.

Specifically, the plurality of second network nodes respectively send different synchronization signals corresponding to each second network node by using the same or different third frequency band resources; in short, each second network node corresponds to a third frequency band resource, but the third frequency band resources corresponding to different second network nodes may be the same or different.

The third frequency band resource is a plurality of same or different time-frequency domain positions in the full frequency band resource of the second cell. For example, the third frequency band resources span the full frequency band resources of the second cell, but only occur in part of the time-frequency domain; again, for example, the third frequency band resource spans a portion of the frequency band resources of the second cell, but also only appears in a portion of the time-frequency domain.

Step 42, receiving the same second system message sent by each second network node, and camping on a second cell to which a plurality of second network nodes belong according to the same second system message; wherein the terminal is capable of determining whether the network node belongs to the second cell according to the information of the network node.

The specific network side may notify the terminal, the mapping relationship between the network node and the TA (Tracking Area) in a broadcast or dedicated signaling manner, so that the idle terminal performs the TA Area update process. It should be noted that multiple cells may be configured with the same TA, but one cell may only belong to one TA.

In this step, the second network node may send the same second system message synchronously, or may send the same second system message asynchronously, which is not limited specifically herein.

Further, the terminal may determine whether the network node belongs to the second cell according to the information of the network node according to a predetermined rule, for example, if the first N digits of the ID of the network node are the same, the network node is considered to belong to the same second cell. Or the sent downlink synchronization signals have some same characteristics, for example, the sending resource positions are the same, or some information carried by the signals is consistent, the signals are considered to belong to the same second cell; the terminal can also know the information by broadcasting the system message of the cell to the terminal, at this time, the second system message of the second cell includes the information of all the second network nodes belonging to the second cell, and the terminal compares the information of the current network node with the information of all the second network nodes belonging to the second cell, so that whether the network node belongs to the second cell can be accurately determined.

Specifically, the information of all second network nodes belonging to the second cell included in the second system message may be identifiers of all second network nodes belonging to the second cell; the characteristics of the synchronization signals transmitted by all second network nodes belonging to the second cell, the characteristics of the synchronization signal identifications, and the like may also be considered. Specifically, the information of all the second network nodes belonging to the second cell may be stored in a form of a table, so that the terminal can conveniently determine whether the synchronized network nodes belong to the same cell.

In this embodiment, since each network node transmits a distinct synchronization signal, the idle terminal is synchronized with each different network node, and can distinguish the network nodes. However, the broadcast system message is still the same information sent by each network node, that is, for an idle terminal, although synchronization is established with different network nodes, the same system information is sent by different network nodes belonging to the same cell, and the system information carries information about which network nodes are included in the cell, and the synchronization signals or identifiers of these network nodes have which characteristics, so that the terminal can determine whether the network nodes synchronized by the terminal belong to a cell, thereby completing the operation of camping on the cell.

In the above embodiment of the present invention, the step of receiving the second system message specifically includes: and the terminal acquires the time-frequency domain position for receiving the second system message according to a pre-configured or standard specified mode (such as a broadcasting mode), and reads the second system message from the time-frequency domain position. In a second embodiment of the invention the second system messages sent by the plurality of second network nodes are identical. Further, the second system message needs to include corresponding information between the cell and the network node, for example, a network node list included in the cell, or what characteristics are in a synchronization signal or an identification signal of the network node under the cell, so that the terminal can know which network nodes belong to a cell. Similar to the first embodiment, the second system message in the third embodiment of the present invention further includes: full band resources of the second cell, access parameters of the second cell, and camping and cell selection information of the second cell. And the terminal selects to reside the second cell according to the residence and cell selection information and the like.

Further, in the foregoing embodiment of the present invention, when the terminal moves to another network node, the cell operation method further includes:

step 43, when the terminal moves, acquiring a synchronization signal of a target network node to which the terminal currently belongs;

step 44, determining whether the target network node belongs to the second cell according to the synchronization signal of the target network node and the information of all the second network nodes belonging to the second cell included in the second system message;

step 45, if the target network node belongs to a second cell, determining that the terminal resides in the second cell;

and step 46, if the target network node does not belong to the second cell, acquiring the system message of the cell to which the target network node belongs, initiating the processes of cell selection and cell reselection, and residing again.

That is, when the terminal moves and moves to another network node, the terminal acquires the synchronization signal again, and determines whether the new network node belongs to the original cell according to the corresponding information of the cell and the network node obtained from the system message before, if the new network node belongs to the original cell, the new network node still resides in the same cell, the received system message can be used, if the new network node does not belong to the same cell, the system message needs to be read again, and the determination is performed according to the principles of cell selection and cell reselection, and the new network node resides again.

After the terminal successfully camps on the second cell and obtains the basic parameters of access from the second system message, if the terminal has a need for data transmission, etc. to perform a connected state, then in a third embodiment of the present invention, after step 42, the cell operation method further includes:

step 47, accessing at least one second network node which is synchronized with the terminal in downlink timing according to the same second system message; after the terminal accesses at least one second network node, the terminal enters a connected state from an idle state.

Step 48, receiving a fourth frequency band resource configured for the terminal by at least one second network node to which the terminal successfully accesses, and performing data transmission with the second network node through the fourth frequency band resource; the fourth frequency band resource is all or part of the remaining frequency band resources obtained by removing all the third frequency band resources from the full frequency band resources of the second cell.

After the terminal enters the connected state, the network side needs to configure the terminal with the optimal transmission resource, i.e., the fourth frequency band resource. The fourth frequency band resource is provided by a different second network node on the same or a different frequency band. It should be noted that the remaining frequency band resources are reusable transmission resources, that is, the same frequency band resource can be reused by different terminals, where it is necessary to avoid interference between different terminals.

Specifically, in the third embodiment of the present invention, step 47 includes:

step 471, accessing at least one second network node according to the access parameter of the second cell in the second system message; the access parameter includes access code configuration information and/or access resource configuration information.

Further, step 471 includes:

step 4711, determining an access code and/or an access resource of the terminal according to the access code configuration information and/or the access resource configuration information;

step 4712, transmitting the access code to at least one second network node or transmitting data information to at least one second network node on the access resource;

step 4713, receiving the identification information and uplink transmission resource allocated by the second network node to the terminal, which are returned by the at least one second network node, and the terminal successfully accesses the at least one second network node.

The terminal can initiate the sending of the uplink access code; or,

Further, after the terminal completes the initial access and before receiving the fourth frequency band resource, the cell operation method further includes:

step 49, reporting the capability information of the terminal to the second network node which is successfully accessed; that is, after the initial access is completed and the terminal enters the connection state, the terminal reports the capability information of the terminal to the second network node, wherein the capability information comprises the supported receiving frequency band and the receiving frequency band combination information.

Step 410, receiving a configuration signaling generated by the second network node according to the capability information and the preliminary measurement result of the terminal, and measuring other network nodes indicated in the configuration signaling according to the configuration signaling; namely, the terminal receives the configuration signaling of the network side, and measures the relevant network nodes according to the configured transmission node set or measurement set.

Step 420, reporting the measurement result to the second network node, so that the second network node can configure a fourth frequency band resource for the terminal or configure a new network node for the terminal according to the measurement result.

The terminal reports the measurement result, if the measurement result is the measurement result of layer three (medium access control layer), the measurement result is reported by RRC signaling, and if the measurement result is the measurement result of layer one (physical layer), the measurement result is reported by a mode of layer one or layer two (RRC layer). After the measurement result is reported to the second network node, receiving the reconfiguration signaling of the configuration set or the measurement set sent by the network side, starting a new set and related operations, receiving the layer-one-layer-two signaling of the rapid service node adjustment sent by the network side, and transmitting the signaling on the new service transmission node.

In summary, in the third embodiment of the present invention, each network node sends a different synchronization signal, and the system message broadcasted by the network carries the corresponding relationship between the cell and the network node; when the idle terminal moves, if the new network node and the original network node belong to different cells, the system message needs to be read again, or cell selection and reselection processes are executed; when the idle terminal moves, the new network node and the original network node belong to the same cell, the system message does not need to be read again, and the received system message can be continuously used; the terminal initiates an access process on the access resource; after the terminal enters a connection state, one or more transmission nodes provide data transmission service on the same frequency band or different frequency bands for the terminal; the data transmission resources can be multiplexed in the frequency band range of the whole cell, so that the overhead of common signaling is reduced except the resources for transmitting system messages and synchronous signals, the system efficiency is improved, and good user experience is ensured.

Step 52, a plurality of second network nodes send the same second system message, so that the terminal can camp on second cells to which the plurality of second network nodes belong according to the second system message; wherein the terminal is capable of determining whether the network node belongs to the second cell according to the information of the network node.

In the above embodiment of the present invention, the step of receiving the second system message specifically includes: and the terminal acquires the time-frequency domain position for receiving the second system message according to a pre-configured or standard specified mode (such as a broadcasting mode), and reads the second system message from the time-frequency domain position.

Further, the second system message needs to include corresponding information between the cell and the network node, for example, a network node list included in the cell, or what characteristics are in a synchronization signal or an identification signal of the network node under the cell, so that the terminal can know which network nodes belong to a cell. Similarly to the third embodiment, the second system message in the fourth embodiment of the present invention further includes: full band resources of the second cell, access parameters of the second cell, and camping and cell selection information of the second cell. And the terminal selects to reside the second cell according to the residence and cell selection information and the like.

In a fourth embodiment of the present invention, a network side of a centralized architecture is used for illustration, where network nodes in the centralized architecture are divided into transmission nodes and a centralized node, and the centralized node is located at a control layer of the network side and can control a plurality of transmission nodes. For the network side, in order to implement the above-mentioned terminal camping process, the required operation is basically similar to that of the second embodiment, and additionally, it is necessary to plan which network nodes belong to one cell, and send the correspondence between the network nodes and the cells to the terminal in a broadcast manner, so that the terminal can make cell-level selection.

After the terminal successfully camps on the first cell and obtains the basic parameters of access from the first system message, if the terminal has a need for data transmission, etc. to perform a connected state, step 52 in the first embodiment of the present invention is followed by the cell operation method further comprising:

and step 54, allocating identification information and uplink transmission resources to the terminal according to the access code or the data information, and determining that the terminal is successfully accessed to the second network node. Specifically, from the perspective of the network side, the network side needs to send the configuration required by the terminal access to the terminal in a broadcast manner; the transmission node receives the access code or data information sent by the terminal on the uplink competition resource, and replies according to different conditions:

Step 55, configuring a fourth frequency band resource for a terminal which is successfully accessed, and performing data transmission with the terminal through the fourth frequency band resource; the fourth frequency band resource is all or part of the remaining frequency band resources obtained by removing all the third frequency band resources from the full frequency band resources of the second cell.
