Detailed ways

The characteristics and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only configured to explain the present invention, not to limit the present invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.

It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is a relationship between these entities or operations. There is no such actual relationship or order between them. Furthermore, the term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus comprising a set of elements includes not only those elements, but also includes elements not expressly listed. other elements of or also include elements inherent in such a process, method, article, or device. Without further limitations, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device that includes the element.

In order to meet the needs of some operators for the rapid deployment of the 5th generation mobile communication technology (5G), the 5G standard introduces a new networking architecture, that is, non-standalone networking (Non Standalone, NSA) , while the traditional second generation mobile communication technology (the 2th generation mobile communication technology, 2G)/third generation mobile communication technology (the 3rd generation mobile communication technology, 3G)/the fourth generation mobile communication technology (the 4th generation mobile communication technology, 4G) The network adopts an independent networking (Standalone, SA) architecture.

When the 5G network adopts the NSA mode, it is attached to the 4G network to work. That is, the 4G LTE site is upgraded to support NSA signaling to carry control plane information, and the New Radio (NR) cell serves as a user plane offload node to provide 5G services. The NSA terminal signaling plane and user plane communicate with the network respectively through The LTE cell and the NR cell are connected.

It can be seen that the 5G network in NSA mode cannot work independently, and it needs to carry signaling through LTE frequency resources. In NSA mode, LTE serves as the anchor network of the 5G network, and the frequency used to carry signaling on LTE is called the anchor. If the terminal fails to occupy the anchor cell in time, it will result in the inability to initiate 5G services. Therefore, in order to ensure the signaling connection between the terminal and the network, it is necessary to give priority to ensuring that the terminal resides on the anchor frequency.

At present, there are two anchor point priority solutions: the anchor point priority scheme based on the wireless side and the anchor point priority scheme based on SPID.

Solution 1: Anchor point priority based on the wireless side

In the idle state, in the IMMCI message element of the RRC_Connection_Release message, the priority of the anchor point is sent to the 5G terminal to guide the terminal to reselect to the anchor frequency. In the case of the connected state, the anchor frequency measurement control (A5 event) is issued to guide the terminal to switch to the anchor frequency.

Scheme 2: SPID-based anchor point priority scheme

For the manufacturer's area that does not support the anchor point priority function on the wireless side, it is necessary to cooperate with the core network and adopt the anchor point priority scheme based on SPID. In the idle state, similar to the anchor point priority function on the wireless side, for users in the 5G SPID group, the anchor frequency point is carried in the IMMCI message element in the RRC_Connection_Release message, and the priority is the highest, and the terminal is guided to reselect to the anchor point frequency. In the connected state, only the neighbor cell information of the anchor frequency is configured for the user in the 5G SPID. When the user is in the connected state, the measurement control issued only includes the anchor frequency, and the terminal is guided to switch to the anchor frequency.

However, there are the following problems in the scheme of specifying the anchor frequency priority by the network side:

First of all, the disadvantage of the anchor point priority scheme based on the wireless side is that it requires additional configuration on the network side. When there are missing or wrong configurations, the anchor point priority configuration error will occur, resulting in the terminal being unable to access the anchor point frequency or access the anchor point. The frequency delay is relatively large, and additional development of network equipment is required to implement related functions.

Secondly, the disadvantage of the SPID-based anchor priority scheme is that it requires the cooperation of the core network to realize the stable residence of 5G terminals in the anchor cell, and the user classification management is complicated.

Therefore, the embodiment of the present invention provides an anchor point resident method, terminal, system and storage medium, which can improve the efficiency of connecting the terminal to the NSA.

In order to facilitate the understanding of the embodiment of the present invention, firstly, the terminal-based anchor priority camping system provided by the embodiment of the present invention is described in detail.

FIG. 1 is a schematic structural diagram of a terminal-based anchor priority camping system provided by an embodiment of the present invention.

As shown in Figure 1, the terminal side-based anchor point priority camping system provided by the embodiment of the present invention includes: a terminal 101, a long term evolution (Long Term Evolution, LTE) master node 102, and a new air interface (New Radio, NR) slave node 103. Core network (5G-enabled EPC) 104.

The terminal 101 supports a 4G or 5G dual-mode terminal in NSA mode. The control plane is connected to the 4G network, and the user plane is connected to the 5G network. At the same time, the terminal 101 also includes an anchor frequency storage module, which can record the once accessed anchor frequency and the disconnection time with the anchor frequency. The terminal 101 can also adjust mobility parameters according to the frequency priority, such as the start-up threshold, the decision threshold, etc., and the terminal can also add neighbor relationship through the auxiliary base station.

The LTE master node 102 is an upgraded 4G base station node, and the upgraded LTE master node can serve as an anchor cell, and provide NSA terminal 101 with a control plane bearer through the anchor frequency.

The NR secondary node 103 is a 5G base station node in NSA mode, and provides user plane bearer for the NSA terminal 101 through the 5G access network technology.

The core network 104 is the upgraded core network (Evolved Packet Core, EPC) of the 4G network. After the upgrade, it can support the management of 5G network signaling and 5G access network equipment, and coordinate the data flow between the control plane and the user plane for the 5G terminal 101. .

Based on the system architecture shown in FIG. 1 , an embodiment of the present invention provides an anchor resident method.

Before describing in detail an anchor point camping method provided by an embodiment of the present invention, firstly, a method for storing an anchor point frequency information table by a terminal is introduced.

Fig. 2 is a schematic flowchart of a method for a terminal to store an anchor point frequency information table according to an embodiment of the present invention.

As shown in FIG. 2, the method for the terminal to store the anchor frequency information table provided by the embodiment of the present invention includes:

S201: Determine an anchor frequency for connecting to an anchor and a disconnection time when disconnecting from the anchor frequency.

S202: Generate an anchor frequency information table according to the anchor frequency and the disconnection time.

The anchor frequency information table includes the anchor frequency and the disconnection time corresponding to the anchor frequency.

Among them, the terminal is a 5G terminal that supports NSA. The terminal's access to the 4G LTE cell and the 5G NR cell can be the normal access when the terminal is turned on to search for the network; it can also be the terminal reselecting to a new serving cell to access the 4G LTE cell and the 5G NR cell; The new serving cell is connected to the 4G LTE cell and the 5G NR cell.

When a terminal accesses a 4G LTE cell and a 5G NR cell, it needs to stay at the anchor point of the 4G LTE cell. The terminal will store the anchor frequency of the 4G LTE cell where it resides. And when the terminal disconnects from the anchor frequency, the terminal stores the time when it disconnects from the anchor frequency. Wherein, disconnecting from the anchor frequency means that the terminal is off the network, such as leaving the network when the device is turned off or power off, the terminal is reselected to a new anchor cell, and the terminal is handed over to a new anchor cell.

An anchor frequency information table is generated by combining the anchor frequencies where the terminal resides and the disconnection time corresponding to each anchor frequency. The anchor frequency information table may record multiple anchor frequencies that the terminal has camped on and the disconnection time corresponding to each anchor frequency in the form of a list.

If the recorded disconnection time exceeds the preset time threshold from the current time, the record can be deleted. If the same anchor frequency has a disconnection time closer to the current time, update the disconnection time of the anchor frequency, as shown in Table 1 below, which is an example of the anchor frequency information table stored in the form of a list.

Table I

Based on the anchor point priority camping system based on the terminal side in FIG. 1 and the method for the terminal to store the anchor point frequency information table in FIG. 2 , an anchor point camping method provided by an embodiment of the present invention is described in detail below.

Fig. 3 is a schematic flowchart of an anchor resident method provided by an embodiment of the present invention.

As shown in Figure 3, the anchor point resident method provided by the embodiment of the present invention includes:

S301: Obtain the broadcast information of the wireless cell and the signal receiving power of the wireless cell; the broadcast information includes multiple network frequencies of adjacent cells of the wireless cell, and the start-up threshold and target corresponding to each network frequency among the multiple network frequencies threshold.

The start-up threshold refers to the threshold for measuring the received power of a signal at a specified frequency. Each signal frequency corresponds to a detection threshold. When the signal strength of the terminal in the serving cell is lower than the start-up threshold, it starts to measure the received power of the signal frequency corresponding to the start-up threshold.

Multiple network frequencies of neighboring cells of the wireless cell can be determined through broadcast messages of the wireless cell, and a start-up threshold value and a target threshold value of each network frequency can be determined.

Wherein, the target threshold may be a reselection threshold or a handover threshold. The reselection threshold refers to the threshold for the terminal to select whether to switch to other cells by monitoring the signal quality of the current serving cell and neighboring cells in idle mode.

S302: Determine the target anchor frequency according to the pre-stored anchor frequency information table; and determine the start-up threshold of the target anchor frequency according to the start-up thresholds of multiple network frequencies and the pre-stored anchor frequency information table.

The anchor frequency information table is pre-stored by the terminal, and includes a plurality of anchor frequencies and a disconnection time corresponding to each anchor frequency. The target anchor frequency can be determined according to the anchor frequency information table. Wherein, the target anchor frequency is an anchor frequency among multiple anchor frequencies in the anchor frequency information table.

Specifically, the target anchor frequency is determined according to the pre-stored anchor frequency information table, including:

Determine the target anchor frequency according to the disconnection time of each anchor frequency in the anchor frequency information table;

Wherein, the disconnection time of the target anchor frequency is the closest disconnection time to the current time.

The target anchor frequency is determined according to the disconnection time corresponding to each anchor frequency in the anchor frequency information table. Wherein, according to the disconnection time of each anchor frequency in the anchor frequency information table, the time length between the disconnection time and the current time is determined. The shorter the time length, the higher the "freshness" of the anchor frequency corresponding to the disconnection time. The anchor frequency with the highest "freshness" can be used as the target anchor frequency.

In the embodiment of the present invention, the priority of the frequency of the anchor point can be determined by the value of the start-up threshold.

After the target anchor frequency is determined, it is also necessary to determine the start-up threshold of the target anchor frequency. In order to be able to camp on the target anchor frequency, here, it is necessary to adjust the priority of the target anchor frequency to the highest priority according to the start-up thresholds of multiple network frequencies of adjacent cells and the anchor frequency information table . The anchor frequency with high priority is the anchor frequency for priority access.

For example, the frequencies and start-up thresholds of adjacent cells in the broadcast information are shown in Table 2:

Table II

Neighboring cell frequency Start-up threshold f1 -80dBm f2 -90dBm f3 -100dBm

Based on the anchor frequency information table in Table 1, the anchor frequency that can be selected is shown in Table 3:

Table three

anchor frequency departure time fm1 20191011093325 fm2 20191010180522

In Table 3, the time to leave the cell where frequency fm1 is located is the closest to the current time. Therefore, fm1 has the highest priority, followed by fm2. If it happens that f3=fm1, that is, there is a certain frequency and storage module in the frequency of the neighboring cell broadcast. The frequency of an anchor point in is the same, the adjusted results are shown in Table 4:

Table four

S303: Determine the measured value of the received power of the target anchor frequency according to the start-up threshold of the target anchor frequency and the signal received power of the wireless cell.

The signal quality of the radio cell can be determined from the signal reception power of the radio cell. Whether the signal quality of the wireless cell is higher than the signal quality of the cell where the target anchor frequency is located may be determined according to the start-up threshold of the target anchor frequency.

Specifically, determine whether the received signal power of the wireless cell is less than the start-up threshold of the target anchor frequency;

When the received signal power of the wireless cell is less than the start-up threshold value of the target anchor frequency, the measured value of the received power of the target anchor frequency is determined.

Comparing the signal received power of the wireless cell with the start-up threshold of the target anchor frequency, if the signal received power of the wireless cell is lower than the start-up threshold, the signal quality of the wireless cell is poor, and you can connect to other wireless cells for anchoring. Click to stay. The target anchor frequency has the highest priority. After determining that the signal reception power of the wireless cell is lower than the start-up threshold of the target anchor frequency, measure the signal reception power of the target anchor frequency to obtain the signal reception frequency of the target anchor. measured value.

S304: Camp on the target anchor frequency according to the measured value of the received power of the target anchor frequency, the anchor frequency information table, and the target threshold.

The target threshold may be a reselection threshold or a handover threshold. When the terminal is in an idle state, the target threshold is the reselection threshold. When the terminal processes the service state, the target threshold value is the switching threshold value.

Firstly, for the case where the target threshold value is the reselection threshold value, the anchor camping of the terminal is introduced in detail.

Specifically, when the target threshold value is the reselection threshold value, according to the measured value of the received power of the target anchor frequency, the anchor frequency information table and the target threshold value, the target anchor frequency is settled, including:

Determine the reselection offset according to the anchor point frequency information table;

When the measured value of the received power of the target anchor frequency is greater than the difference between the reselection threshold and the reselection offset, camp on the target anchor frequency.

The reselection offset is determined based on the anchor frequency. The reselection offset can make it easier for the terminal to reselect to the target anchor frequency, so that the terminal can camp on the target anchor frequency and connect to the wireless cell to which the target anchor frequency belongs. Therefore, the setting of the reselection offset is to reduce the threshold value of reselection into the anchor frequency, that is, the reselection offset is used to adjust the reselection threshold value of the broadcast message. For "freshness" The higher the anchor frequency, the lower the reselection threshold.

Determine the reselection offset according to the anchor frequency information table. Based on the reselection criterion, the difference between the reselection threshold and the reselection offset is calculated. When the measured value of the received power of the target anchor frequency is greater than the difference between the reselection threshold and the reselection offset, camp on the target anchor frequency. When the measured value of the received power of the target anchor frequency is not greater than the difference between the reselection threshold and the reselection offset, wait for the terminal to detect that the signal received power of the current wireless cell drops below the start threshold of the target anchor frequency , the reselection decision is triggered again: when the re-determined signal received power of the wireless cell is less than the start-up threshold of the target anchor frequency, re-determine the measured value of the received power of the target anchor frequency. When the re-determined measured value of the received power of the target anchor point is greater than the difference between the reselection threshold and the reselection offset, the frequency of the target anchor point is parked.

Here, in the anchor point reselection process, the reference signal receiving power (Reference Signal Receiving Power, RSRP) of the broadcast channel or pilot channel of the anchor point frequency is usually measured.

Secondly, for the case where the target threshold value is the switching threshold value, the anchor camping of the terminal is introduced in detail.

Specifically, when the target threshold value is the switching threshold value, according to the measured value of the received power of the target anchor frequency, the anchor frequency information table and the target threshold value, the target anchor frequency is settled, including:

Determine the handoff offset according to the anchor point frequency information table;

When the measured value of the received power of the target anchor frequency is greater than the difference between the handover threshold and the handover offset, it is determined to camp on the target anchor frequency.

Wherein, the switching offset is determined according to the frequency of the anchor point. The handover offset can make it easier for the terminal to switch to the target anchor frequency, so that the terminal can camp on the target anchor frequency and connect to the wireless cell to which the target anchor frequency belongs. Therefore, the setting of the switching offset is to reduce the threshold value of switching into the anchor point frequency, that is, the switching offset parameter is used to adjust the switching threshold value of the broadcast message, and for the anchor point with high "freshness" frequency, the switching threshold is lower.

Determine the handover offset according to the anchor frequency information table. Based on the handover criterion, the difference between the handover threshold and the handover offset is calculated. When the measured value of the received power of the target anchor frequency is greater than the difference between the handover threshold and the handover offset, camp on the target anchor frequency. When the measured value of the received power of the target anchor frequency is not greater than the difference between the handover threshold and the handover offset, wait for the terminal to detect that the signal received power of the current wireless cell drops below the start threshold of the target anchor frequency, Re-triggering the handover decision: when the re-determined signal received power of the wireless cell is less than the start-up threshold of the target anchor frequency, re-determine the measured value of the received power of the target anchor frequency. When the re-determined measured value of the received power of the target anchor point is greater than the difference between the handover threshold and the handover offset, the frequency of the target anchor point is parked.

In addition, the wireless cell to which the target anchor frequency belongs may not be a neighboring cell of the wireless cell where the current terminal is located. Therefore, before determining the resident target anchor point, the embodiment of the present invention may further include the following steps:

Determine whether the wireless cell corresponding to the target anchor frequency is an adjacent cell; when the wireless cell is not an adjacent cell, obtain the information of the base station of the wireless cell corresponding to the target anchor frequency; establish a connection with the base station according to the information of the base station.

Wherein, when the target anchor frequency meets the handover criterion, the wireless cell to which the target anchor frequency belongs may not be a neighboring cell of the wireless cell where the terminal is located. Then, it is necessary to establish a connection to the base station corresponding to the wireless cell to which the target anchor frequency belongs.

The information of the base station of the wireless cell to which the target anchor frequency belongs may be obtained. According to the information of the base station, a connection is established with the base station. For example, the X2 interface may be established according to the self-establishment connection condition of the X2 interface to complete the connection with the base station.

The anchor point camping method provided by the embodiment of the present invention obtains the broadcast information of the wireless cell and the signal receiving power of the wireless cell; the broadcast information includes multiple network frequencies of adjacent cells of the wireless cell, and each of the multiple network frequencies The start-up threshold and target threshold corresponding to the network frequency; determine the target anchor frequency according to the pre-stored anchor frequency information table; and according to the start-up threshold of multiple network frequencies and the pre-stored anchor frequency information Table determines the start-up threshold value of the target anchor frequency; according to the start-up threshold value of the target anchor frequency and the signal reception power of the wireless cell, determine the measured value of the received power of the target anchor frequency; according to the target anchor frequency The measured value of the received power, the anchor frequency information table and the target threshold value, and the dwell target anchor frequency can improve the efficiency of the terminal connecting to the NSA.

Fig. 4 is a schematic flowchart of a method for reselecting a new anchor point provided by an embodiment of the present invention.

As shown in Figure 4, a method for reselecting a new anchor point provided by an embodiment of the present invention includes:

S401: Receive a broadcast message from a serving cell, and acquire a start-up threshold and a reselection threshold corresponding to frequencies of each neighboring cell from the broadcast message.

The threshold in this step is usually delivered by broadcast in the System Information Block (SIB) information.

The so-called start-up threshold means that the terminal starts to measure the received signal power of a specified frequency when the signal strength of the serving cell is lower than a certain set threshold value. When the relationship among the signal received power measurement value corresponding to the designated frequency, the reselection threshold value, and the signal received power of the serving cell satisfies the reselection criterion, reselection is performed. Wherein, a certain set threshold value is the start-up threshold corresponding to the designated frequency. Usually, a serving cell has multiple adjacent cells. Therefore, there are multiple adjacent cell frequencies, and each adjacent cell frequency has its corresponding start-up threshold.

Operators will set the frequency priority of adjacent cells according to network policies or business policies. The frequency with high priority is the frequency for priority access. The operator realizes priority access by setting a higher start-up threshold for this frequency. For example, when the received power of the current service signal does not drop much, that is, the condition of the start-up threshold is reached, and the neighbor cell is started to be measured, thereby It is easier to start the reselection process, making it easier for the terminal to reselect to a high-priority frequency. It can be seen that the start-up thresholds corresponding to the frequencies of each neighboring cell sent in the broadcast message are different, as shown in Table 2 in the above-mentioned embodiment is an example of an adjacent cell frequency corresponding to the start-up threshold.

S402: Obtain an anchor frequency information table from the anchor frequency list recorded in the storage unit of the terminal.

Here, the anchor frequency information table includes frequency and departure time, and this information is the anchor frequency information table pre-stored by the terminal in the embodiment corresponding to FIG. 2 .

S403: According to the anchor point frequency information table and the received broadcast message, adjust the start-up threshold corresponding to each frequency that the terminal needs to measure during reselection, and determine the reselection offset parameter according to the anchor point frequency information table.

The criterion for adjusting the start-up threshold here is to increase the priority of the anchor frequency to make it easier for the terminal to reselect to the anchor frequency of the anchor cell. Therefore, when adjusting the start-up threshold, increase the anchor frequency corresponding to The specific criteria for adjustment include: the priority of the anchor frequency is higher than that of the non-anchor frequency. In the anchor frequency, the "freshness" of the anchor frequency is determined according to the difference between the departure time and the current time. The closer the departure time, the fresher the anchor frequency is; the higher the freshness of the anchor frequency, the start gate The higher the limit. If one or more frequencies of the adjacent cell frequencies sent by the original broadcast message are in the anchor frequency list of the terminal, then the frequencies in the anchor frequency list are prioritized according to the anchor frequency and freshness.

The following is an example of how to adjust:

The start-up threshold corresponding to the frequency of the adjacent cell delivered by the broadcast message is shown in Table 2, and the anchor frequency information table queried in the terminal anchor frequency list is shown in Table 3 in the foregoing embodiment. In Table 3, _the time of leaving the cell where frequency f _m1 is located is _the closest to the current time in the list, so its priority is the highest, followed by f _m2 . If a certain frequency is the same as a certain anchor point frequency in the storage module, the adjusted result is shown in Table 4 in the above embodiment.

The purpose of setting the reselection offset parameter is to make it easier for the terminal to reselect to the anchor frequency, and try to make the terminal stay on the anchor frequency and connect to the anchor cell. Therefore, the setting of the offset value is to reduce the threshold value of reselection into the anchor frequency, that is, the reselection offset parameter is used to adjust the reselection threshold value of the broadcast message. For anchor frequencies with high "freshness", the reselection threshold is lower;

S404: When the terminal in the idle state detects that the signal receiving power of the current serving cell has dropped below a certain start-up threshold, it measures the received power of the frequency corresponding to the start-up threshold, and according to the measured value of the received power, the reselection threshold, The reselection offset parameter is used to make a reselection decision.

Wherein, the reselection criterion is: when the measured value of the received power of the anchor frequency is greater than the difference between the reselection threshold and the reselection offset parameter, the anchor frequency is reselected for camping.

During the reselection process, the RSRP of the broadcast channel or pilot channel of the anchor frequency is usually measured.

S405: Whether the reselection criterion is satisfied, if the reselection criterion is met, go to step 206, if the reselection criterion is not satisfied, return to S404, wait for the terminal to detect that the signal receiving power of the current serving cell has dropped below a certain start-up threshold, and trigger again Re-election decision.

S406: The terminal performs reselection.

The embodiment of the present invention provides a new anchor point reselection method, which enables the terminal to adjust the parameters in the process of terminal reselection according to its pre-stored anchor point frequency information table in the idle state, so that the terminal can quickly capture to the anchor frequency, which improves the reselection efficiency of 5G NSA terminals.

Fig. 5 is a schematic flowchart of a method for switching a new anchor point provided by an embodiment of the present invention.

As shown in FIG. 5, a method for switching a new anchor point provided by an embodiment of the present invention includes:

S501: Receive a broadcast message from the serving cell, and obtain the start-up threshold and handover threshold corresponding to the frequency of each neighboring cell from the broadcast message;

The threshold in this step is usually issued in the SIB information by broadcasting.

The so-called start-up threshold means that the terminal starts to measure the received signal power of a specified frequency when the signal strength of the serving cell is lower than a certain set threshold value. When the relationship among the signal received power measurement value corresponding to the specified frequency, the handover threshold value, and the signal received power of the serving cell satisfies the handover criterion, the handover is performed. Wherein, a certain set threshold value is the start-up threshold corresponding to the designated frequency. Usually, a serving cell has multiple adjacent cells. Therefore, there are multiple adjacent cell frequencies, and each adjacent cell frequency has its corresponding start-up threshold.

Operators will set the frequency priority of adjacent cells according to network policies or business policies. The high-priority frequency is the frequency for priority access, and the operator realizes priority access by setting a higher detection threshold for the frequency. For example, when the receiving power of the current service signal does not drop much, that is, the condition of the start-up threshold is reached, the measurement of the adjacent cell is started, so that it is easier to start the handover process, making it easier for the terminal to handover to a high-priority frequency superior. It can be seen that the start-up thresholds corresponding to the adjacent cell frequencies delivered in the broadcast message are different, and the examples of the start-up thresholds corresponding to the adjacent cell frequencies in the handover process are similar to those in Table 2.

S502: Obtain an anchor frequency information table from an anchor frequency list recorded in a storage unit of the terminal.

The anchor frequency information table here includes frequency and departure time, and these information are collected by the process of storing the anchor frequency information table by the terminal.

S503: Adjust the start-up threshold corresponding to each frequency that the terminal needs to measure during handover according to the anchor frequency information table and the received broadcast message, and determine a handover offset parameter according to the anchor frequency information table.

Here, the criterion for adjusting the start-up threshold is to increase the priority of the anchor frequency to make it easier for the terminal to switch to the anchor frequency of the anchor cell. Therefore, when adjusting the start-up threshold, increase the corresponding frequency of the anchor frequency. The start-up threshold value. The specific criteria for adjustment include: the priority of the anchor frequency is higher than that of the non-anchor frequency. In the anchor frequency, the "freshness" of the anchor frequency is determined according to the difference between the departure time and the current time. The closer the departure time, the fresher the anchor frequency is; the higher the freshness of the anchor frequency, the start gate The higher the limit. If one or more frequencies of the adjacent cell frequencies sent by the original broadcast message are in the anchor frequency list of the terminal, then the frequencies in the anchor frequency list are prioritized according to the anchor frequency and freshness.

The following is an example of how to adjust:

The criterion for adjusting the detection start threshold here is to increase the priority of the anchor frequency, so that it is easier for the terminal to reselect to the anchor frequency of the anchor cell. Therefore, when adjusting the start-up threshold, the start-up threshold corresponding to the anchor frequency is increased. The specific criteria for adjustment include: the priority of the anchor frequency is higher than that of the non-anchor frequency. In the anchor frequency, the "freshness" of the anchor frequency is determined according to the difference between the departure time and the current time. The closer the departure time, the fresher the anchor frequency is; the higher the freshness of the anchor frequency, the start gate The higher the limit. If one or more frequencies of the adjacent cell frequencies sent by the original broadcast message are in the anchor frequency list of the terminal, then the frequencies in the anchor frequency list are prioritized according to the anchor frequency and freshness.

The following is an example of how to adjust:

The start-up threshold corresponding to the frequency of the adjacent cell delivered by the broadcast message is shown in Table 2, and the anchor frequency information table queried in the terminal anchor frequency list is shown in Table 3 in the foregoing embodiment. In Table 3, _the time of leaving the _cell where frequency f _m1 is located is the closest to the current time in the list, so its priority is the highest, followed by f _m2 . If a certain frequency is the same as a certain anchor point frequency in the storage module, the adjusted result is shown in Table 4 in the above embodiment.

The goal of setting the handover offset parameter is to make it easier for the terminal to switch to the anchor frequency, and try to make the terminal stay on the anchor frequency and connect to the anchor cell. Therefore, the offset value is set as the gate for switching to the anchor frequency. The limit value is lowered, that is, the handover offset parameter is used to adjust the handover threshold value delivered by the broadcast message. For the anchor frequency with high "freshness", its switching threshold is lower.

S504: When the terminal in the connected state detects that the received signal power of the current serving cell drops below a certain start-up threshold, measure the received power of the frequency corresponding to the start-up threshold. And according to the measured value of the received power, the handover threshold value, and the handover offset parameter, a handover decision is made.

During the handover process, the RSRP of the broadcast channel or the pilot channel is usually measured.

S505: Whether the handover criterion is met, and if the handover criterion is met, go to S506. If the handover criterion is not met, return to before S504. When the waiting terminal detects that the received signal power of the current serving cell drops below a certain start-up threshold, it triggers the handover decision again.

S506: The source serving cell detects whether the target cell corresponding to the frequency satisfying the handover criterion in S505 is in the neighbor cell list. If it is in the list, go to S508. If not in the list, go to S507.

S507: Add the target cell to the neighbor cell list, and obtain information about the base station of the target cell. Establish the X2 interface according to the X2 interface self-establishment condition setting.

S508: The terminal performs switching.

The embodiment of the present invention provides a new anchor point switching method, which enables the terminal to adjust the offset of the parameters in the existing terminal switching process according to the anchor point frequency information table recorded by the terminal in the connected state, and at the same time When the anchor cell corresponding to the anchor frequency that is not configured as a neighboring cell is determined as the target cell, it is configured as a neighbor cell relationship, so that the terminal can quickly switch to the anchor frequency, and the handover efficiency of the 5G NSA terminal is improved.
