Detailed Description

Features of various aspects and exemplary embodiments of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the 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 merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrases "comprising 8230; \8230;" comprise 8230; "do not exclude the presence of additional identical elements in any process, method, article, or apparatus that comprises the element.

In order to meet the demand of rapid deployment of fifth generation mobile communication technology (5G) by some operators, the 5G standard introduces a new networking architecture, i.e., non-independent Networking (NSA), while the conventional second generation mobile communication technology (2G)/third generation mobile communication technology (3G)/fourth generation mobile communication technology (4G) network adopts an architecture of independent networking (SA).

When the 5G network adopts the NSA mode, the network is attached to the 4G network to work. Namely, the LTE site upgrade of 4G is used to support signaling as NSA to carry control plane information, a New Radio (NR) cell is used as a user plane offload node to provide 5G services, and the NSA terminal signaling plane and the user plane are connected to the network through the LTE cell and the NR cell, respectively.

Therefore, the 5G network in the NSA mode cannot work independently and needs to bear signaling through frequency resources of LTE, the LTE in the NSA mode serves as an anchor point network of the 5G network, and the frequency used for bearing the signaling on the LTE is referred to as an anchor point frequency.

There are currently two anchor-first solutions: an anchor priority scheme based on the wireless side and an anchor priority scheme based on the SPID.

The first scheme comprises the following steps: anchor point priority scheme based on wireless side

In the idle state, in an IMMCI message cell of an RRC _ Connection _ Release message, the IMMCI message cell carries anchor point priority and issues the anchor point priority to a 5G terminal, and the terminal is guided to reselect to an anchor point frequency. And under the condition of the connection state, transmitting anchor frequency measurement control (A5 event) and guiding the terminal to switch into the anchor frequency.

Scheme two is as follows: anchor priority scheme based on SPID

For the manufacturer area which does not support the anchor point priority function of the wireless side, the cooperation of a core network is needed, and an anchor point priority scheme based on the SPID is adopted. In an idle state, similar to a wireless side anchor priority function, for a user in the 5G SPID group, an anchor frequency point is carried in an IMMCI message cell in an RRC _ Connection _ Release message, and the priority is highest, so that the terminal is guided to reselect to the anchor frequency. And under the condition of a connection state, only configuring the adjacent region information of the anchor point frequency for the user in the 5G SPID, and when the user is in a connection state, issuing measurement control only containing the anchor point frequency to guide the terminal to switch to the anchor point frequency.

However, the scheme of assigning the priority of the anchor frequency by the network side has the following problems:

firstly, the anchor priority scheme based on the wireless side has the disadvantages that the network side needs to be additionally configured, the anchor priority configuration error occurs when the conditions of missing configuration, misconfiguration and the like exist, so that the terminal cannot access the anchor frequency or the time delay of accessing the anchor frequency is large, and the network equipment needs to be additionally developed to realize related functions.

Secondly, the anchor priority scheme based on the SPID has the disadvantages that the 5G terminal can stably reside in the anchor cell only by the cooperation of the core network, and the user classification management is complex.

Therefore, the embodiment of the invention provides an anchor point residing method, a terminal, a system and a storage medium, which can improve the efficiency of connecting the terminal with the NSA.

For convenience of understanding the embodiment of the present invention, a detailed description will be first given of the anchor point-first-residence system based on the terminal side according to the embodiment of the present invention.

Fig. 1 is a schematic structural diagram of an anchor point preferential residence system based on a terminal side according to an embodiment of the present invention.

As shown in fig. 1, the anchor point preferential residence system based on the terminal side according to the embodiment of the present invention includes: a terminal 101, a Long Term Evolution (LTE) primary node 102, a New Radio (NR) secondary node 103, and a core network (5G-enabled EPC) 104.

The terminal 101 supports a 4G or 5G dual mode terminal of the NSA mode. The control plane is accessed to the 4G network, and the user plane is accessed to the 5G network. Meanwhile, the terminal 101 further includes a storage module of anchor frequency, which can record the anchor frequency that has been accessed and the time of disconnection from the anchor frequency. The terminal 101 may also adjust mobility parameters, such as a start threshold, a decision threshold, and the like, according to the frequency priority, and the terminal may also add a neighbor relation through the auxiliary base station.

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

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

The Core network 104 may support management of 5G network signaling and 5G access network equipment after being upgraded by an upgraded Core network (EPC) of the 4G network, and coordinate data flows of 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 point residing method.

Before explaining the anchor residing method provided by the embodiment of the present invention in detail, a method for storing an anchor frequency information table by a terminal is introduced first.

Fig. 2 is a flowchart illustrating a method for storing an anchor frequency information table by a terminal according to an embodiment of the present invention.

As shown in fig. 2, the method for storing an anchor frequency information table by a terminal according to an embodiment of the present invention includes:

s201: determining the anchor point frequency of the connection anchor point and the disconnection time when the connection anchor point frequency is disconnected.

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

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

Wherein, the terminal is a 5G terminal supporting NSA. The terminal access to the 4G LTE cell and the 5G NR cell can be normal access when the terminal is started to search a network; or the terminal reselects to a new service cell to access a 4G LTE cell and a 5G NR cell; the terminal can also be switched to a new serving cell to access a 4G LTE cell and a 5G NR cell.

The terminal accesses to a 4G LTE cell and a 5G NR cell and needs to reside at an anchor point of the 4G LTE cell. The terminal may store the anchor frequency of the 4G LTE cell in which it is camped. And when the terminal is disconnected with the anchor frequency, the terminal stores the time for disconnecting the terminal from the anchor frequency. The disconnection from the anchor frequency means that the terminal is offline, for example, the terminal leaves the network when the terminal is powered off or powered off, the terminal reselects a new anchor cell, and the terminal is switched to the new anchor cell.

And generating an anchor point frequency information table according to the anchor point frequency where the terminal resides and the disconnection time corresponding to each anchor point frequency. The anchor frequency information table may be in a list form, and records a plurality of anchor frequencies in which the terminal resides and disconnection time corresponding to each anchor frequency.

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

Watch 1

Based on the anchor residing system based on the terminal side in fig. 1 and the method for storing the anchor frequency information table by the terminal in fig. 2, an anchor residing method provided by the embodiment of the present invention is explained in detail below.

Fig. 3 is a flowchart illustrating an anchor point camping method according to an embodiment of the present invention.

As shown in fig. 3, the anchor point camping method provided in the embodiment of the present invention includes:

s301: acquiring broadcast information of a wireless cell and signal receiving power of the wireless cell; the broadcast information includes a plurality of network frequencies of neighboring cells of the wireless cell, and a start-up threshold and a target threshold corresponding to each of the plurality of network frequencies.

The start-up threshold is a threshold for measuring the received power of a signal with a specified frequency. Each signal frequency corresponds to a start-up threshold. And when the signal strength of the terminal in the service cell is lower than the measurement starting threshold value, starting to measure the received power of the signal frequency corresponding to the measurement starting threshold value.

A plurality of network frequencies of adjacent cells of the wireless cell can be determined through the broadcast message of the wireless cell, and a start-up threshold value and a target threshold value of each network frequency are determined.

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

S302: determining a target anchor frequency according to a pre-stored anchor frequency information table; and determining the start-up threshold value of the target anchor point frequency according to the start-up threshold values of the plurality of network frequencies and the anchor point frequency information table stored in advance.

The anchor frequency information table is pre-stored by the terminal and comprises a plurality of anchor frequencies and disconnection time corresponding to each anchor frequency. The target anchor frequency can be determined from the anchor frequency information table. The target anchor frequency is one of a plurality of anchor frequencies in the anchor frequency information table.

Specifically, determining the target anchor frequency according to a pre-stored anchor frequency information table includes:

determining a target anchor point frequency according to the disconnection time of each anchor point frequency in the anchor point frequency information table;

and the disconnection time of the target anchor point frequency is the disconnection time closest to the current time.

And the target anchor point frequency is determined according to the disconnection time corresponding to each anchor point frequency in the anchor point frequency information table. And determining the disconnection time of each anchor point frequency according to the anchor point frequency information table, wherein the disconnection time is the time length of the disconnection time and the current time. The shorter the length of time, the higher the "freshness" of the anchor frequency for the disconnection time. The anchor frequency with the highest "freshness" may be taken as the target anchor frequency.

In the embodiment of the present invention, the level of the priority of the anchor frequency may be determined by measuring the threshold value.

After the target anchor point frequency is determined, a measurement starting threshold value of the target anchor point frequency also needs to be determined. In order to camp on the target anchor frequency, the priority of the target anchor frequency needs to be adjusted to the highest priority according to the start-up threshold values of the network frequencies of the neighboring cells and the anchor frequency information table. The anchor frequency with high priority is the anchor frequency with priority access.

For example, the frequencies and the measurement start thresholds of the neighboring cells in the broadcast information are shown in table two:

watch 2

Neighbor cell frequency	Threshold value of start-up test
		f1	-80dBm
f2	-90dBm
		f3	-100dBm

Based on the anchor frequency information table in table one, the anchor frequency that can be selected is as shown in table three:

watch III

Frequency of anchor point	Time of departure
		fm1	20191011093325
fm2	20191010180522

In table three, the time of leaving the cell where the frequency fm1 is located is closest to the current time, so that the priority of fm1 is the highest, fm2 times, and if f3= fm1 exactly, that is, a certain frequency existing in the frequency of the neighboring cell issued by the broadcast is the same as a certain anchor frequency in the storage module, the adjusted result is as shown in table four:

watch four

S303: and determining the measured value of the received power of the target anchor point frequency according to the start-up threshold value of the target anchor point 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. The signal quality of the wireless cell can be determined whether to be higher than the signal quality of the cell where the target anchor frequency is located according to the measurement starting threshold value of the target anchor frequency.

Specifically, determining whether the signal receiving power of the wireless cell is smaller than a start-up threshold value of the target anchor point frequency;

And comparing the signal receiving power of the wireless cell with the start-up threshold of the target anchor point frequency, if the signal receiving power of the wireless cell is lower than the start-up threshold, the signal quality of the wireless cell is poor, and the wireless cell can be connected to other wireless cells for anchor point residence. And after determining that the signal receiving power of the wireless cell is lower than the start-up threshold value of the target anchor point frequency, measuring the signal receiving power of the target anchor point frequency to obtain the measured value of the signal receiving frequency of the target anchor point.

S304: and residing the target anchor point frequency according to the measured value of the receiving power of the target anchor point frequency, the anchor point frequency information table and the target threshold value.

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

First, a detailed description is given to anchor point camping of the terminal for the case that the target threshold is the reselection threshold.

Specifically, when the target threshold is the reselection threshold, residing 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, includes:

The reselection offset is determined based on the anchor frequency. The reselection offset enables the terminal to reselect to the target anchor frequency more easily, and enables the terminal to reside at the target anchor frequency and to be connected with the wireless cell to which the target anchor frequency belongs. Therefore, the reselection offset is set to decrease the threshold of the frequency reselected to the anchor point, that is, the reselection offset is used to adjust the reselection threshold issued by the broadcast message, and for the anchor point frequency with high "freshness", the reselection threshold is lower.

And determining the reselection offset according to the anchor frequency information table. A difference between the reselection threshold value and the reselection offset is calculated based on reselection criteria. And when the measured value of the receiving power of the target anchor point frequency is greater than the difference value of the reselection threshold value and the reselection offset, residing in the target anchor point frequency. When the measured value of the received power of the target anchor point frequency is not greater than the difference value of the reselection threshold value and the reselection offset, when the terminal detects that the signal received power of the current wireless cell is reduced below the target anchor point frequency starting threshold, triggering reselection judgment again: and when the signal receiving power of the wireless cell is determined to be smaller than the start-up threshold value of the target anchor point frequency, the measured value of the receiving power of the target anchor point frequency is determined again. And when the measured value of the received power of the target anchor point obtained by re-determination is larger than the difference value of the reselection threshold value and the reselection offset, residing the target anchor point frequency.

Here, in the anchor reselection process, reference Signal Receiving Power (RSRP) of a broadcast channel or a pilot channel of the anchor frequency is generally measured.

Secondly, the anchor point residence of the terminal is described in detail when the target threshold value is the switching threshold value.

Specifically, when the target threshold is the handover threshold, the camping of the target anchor frequency according to the measurement value of the received power of the target anchor frequency, the anchor frequency information table, and the target threshold includes:

Wherein the handover offset is determined according to the anchor frequency. The handover offset enables the terminal to be more easily handed over to the target anchor frequency, so that the terminal resides on the target anchor frequency and is connected to the wireless cell to which the target anchor frequency belongs. Therefore, the threshold value of the switching-in anchor point frequency is set to be reduced, that is, the switching offset parameter is used for adjusting the switching threshold value issued by the broadcast message, and for the anchor point frequency with high "freshness", the switching threshold value is lower.

And determining the switching offset according to the anchor frequency information table. Based on the handover criterion, a difference between the handover threshold value and the handover offset is calculated. And when the measured value of the receiving power of the target anchor point frequency is larger than the difference value of the switching threshold value and the switching offset, residing the target anchor point frequency. When the measured value of the receiving power of the target anchor point frequency is not larger than the difference value of the switching threshold value and the switching offset, when the terminal detects that the signal receiving power of the current wireless cell is reduced to be below the target anchor point frequency starting threshold, triggering the switching judgment again: and when the signal receiving power of the wireless cell is determined to be smaller than the start-up threshold value of the target anchor point frequency, the measured value of the receiving power of the target anchor point frequency is determined again. And when the measured value of the received power of the target anchor point which is obtained by re-determination is larger than the difference value of the switching threshold value and the switching offset, residing the target anchor point frequency.

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

determining whether a wireless cell corresponding to the target anchor point frequency is an adjacent cell; when the wireless cell is not an adjacent cell, acquiring the information of the base station of the wireless cell corresponding to the target anchor point frequency; and establishing connection with the base station according to the information of the base station.

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 in which the terminal is located. Then, a connection needs to be established to the base station corresponding to the wireless cell to which the target anchor frequency belongs.

Information of a base station of a wireless cell to which the target anchor frequency belongs can be acquired. And establishing connection with the base station according to the information of the base station. For example, the X2 interface may be set up according to the self-connection establishment condition of the X2 interface, and the connection with the base station may be completed.

The anchor point residing method provided by the embodiment of the invention obtains the broadcast information of the wireless cell and the signal receiving power of the wireless cell; the broadcast information comprises a plurality of network frequencies of adjacent cells of the wireless cell, and a start-up threshold value and a target threshold value corresponding to each network frequency in the plurality of network frequencies; determining a target anchor frequency according to a pre-stored anchor frequency information table; determining the start-up threshold value of the target anchor point frequency according to the start-up threshold values of the plurality of network frequencies and a pre-stored anchor point frequency information table; determining a measured value of the receiving power of the target anchor point frequency according to the start-up threshold value of the target anchor point frequency and the signal receiving power of the wireless cell; according to the measured value of the receiving power of the target anchor point frequency, the anchor point frequency information table and the target threshold value, the target anchor point frequency is resided, and the efficiency of the terminal in connection with the NSA can be improved.

Fig. 4 is a flowchart illustrating a reselection method for a new anchor point according to an embodiment of the present invention.

As shown in fig. 4, a method for reselecting a new anchor point according to an embodiment of the present invention includes:

s401: and receiving the broadcast message of the service cell, and acquiring the start-up threshold and reselection threshold corresponding to each adjacent cell frequency from the broadcast message.

The threshold in this step is typically issued by broadcast in System Information Block (SIB) Information.

The measurement starting threshold means that the terminal starts to measure the signal receiving power of a certain specified frequency when the signal strength of the serving cell is lower than a certain set threshold value. And when the relation among the signal receiving power measured value corresponding to the designated frequency, the reselection threshold value and the signal receiving power of the serving cell meets the reselection criterion, performing reselection. Wherein, a certain set threshold value is the start-up threshold corresponding to the specified frequency. Typically, there will be multiple neighboring cells for a serving cell. Therefore, there will be multiple neighboring cell frequencies, and each neighboring cell frequency will have its corresponding measured threshold.

The operator sets the frequency priority of the adjacent cell according to the network strategy or the service strategy. The high priority frequency is the frequency with priority access. The operator realizes the priority access by setting a higher start-up threshold for the frequency, for example, when the received power of the current service signal is not reduced much, that is, the condition of the start-up threshold is reached, the neighbor cell is measured, so that the reselection process is started more easily, and the terminal is easier to reselect the frequency with high priority, and thus it can be known that the start-up thresholds corresponding to the frequencies of the neighbor cells issued in the broadcast message are different, and the above embodiment is an example in which the adjacent cell frequency corresponds to the start-up threshold.

S402: and acquiring 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 frequencies and departure times, and these pieces of information are anchor frequency information tables stored in advance by the terminal in the corresponding embodiment of fig. 2.

S403: and adjusting the start-up threshold value corresponding to each frequency to be measured when the terminal reselects according to the anchor frequency information table and the received broadcast message, and determining the reselection offset parameter according to the anchor frequency information table.

The criterion for adjusting the measurement starting threshold is to increase the priority of the anchor point frequency, so that the terminal can reselect the anchor point frequency of the anchor point cell more easily, therefore, when the measurement starting threshold is adjusted, the measurement starting threshold corresponding to the anchor point frequency is increased, and the specific criterion for adjustment includes: the anchor frequency has a higher priority than the non-anchor frequency. Determining the 'freshness' of the anchor frequency according to the difference value between the leaving time and the current time in the anchor frequency, wherein the closer leaving time indicates that the anchor frequency is fresher; the higher the freshness the higher the anchor frequency, the higher its threshold value of enablement. If one or more frequencies of the adjacent cell frequency sent by the original broadcast message are in the anchor frequency list of the terminal, setting the priority of the frequencies in the anchor frequency list according to the freshness of the anchor frequency.

The following is illustrated by way of example:

the frequency of the neighboring cell sent by the broadcast message corresponds to the start-up threshold as in table two, and the anchor point frequency information table queried in the terminal anchor point frequency list is as in table three in the above embodiments. In Table III, leave f _m1 The time of the cell in which the frequency is located is closest to the current time in the list, and therefore its priority is highest, f _m2 Then, if f is exactly ₃ ＝f _m1 That is, if there is a frequency in the adjacent cell frequency sent by broadcast that is the same as the anchor frequency in the storage module, the adjusted result is as shown in table four in the above embodiment.

The aim of setting the reselection offset parameter is to make the terminal reselect to the anchor frequency more easily, and to make the terminal reside on the anchor frequency and connect with the anchor cell as much as possible. Therefore, the offset value is set to decrease the threshold value of the frequency reselected to the anchor point, i.e. the reselection offset parameter is used to adjust the reselection threshold value issued by 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 service cell is reduced below a certain starting threshold, the terminal measures the receiving power of the frequency corresponding to the starting threshold, and performs reselection judgment according to the measured value of the receiving power, the reselection threshold value and the reselection offset parameter.

Wherein, the reselection criterion is as follows: and reselecting the anchor frequency for residing when the measured value of the receiving power of the anchor frequency is larger than the difference value of the reselection threshold value and the reselection offset parameter.

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

S405: if the reselection criterion is satisfied, the process proceeds to step 206 if the reselection criterion is satisfied, and if the reselection criterion is not satisfied, the process returns to step 404, and when the terminal detects that the signal receiving power of the current serving cell drops below a certain starting threshold, the reselection determination is triggered again.

S406: the terminal performs reselection.

According to the new anchor point reselection method provided by the embodiment of the invention, the terminal adjusts parameters in the terminal reselection process according to the anchor point frequency information table pre-stored in the terminal in an idle state, so that the terminal can quickly capture the anchor point frequency, and the reselection efficiency of the 5G NSA terminal is improved.

Fig. 5 is a flowchart illustrating a method for switching a new anchor point according to an embodiment of the present invention.

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

s501: receiving broadcast messages of a service cell, and acquiring a start-up threshold and a switching threshold corresponding to each adjacent cell frequency from the broadcast messages;

the thresholds in this step are typically issued by the broadcast in SIB information.

The measurement starting threshold means that the terminal starts to measure the signal receiving power of a certain specified frequency when the signal strength of the serving cell is lower than a certain set threshold value. When the relation among the signal receiving power measured value corresponding to the designated frequency, the switching threshold value and the signal receiving power of the service cell meets the switching criterion, switching is executed. Wherein, a certain set threshold value is the start-up threshold corresponding to the specified frequency. Typically, there will be multiple neighboring cells for a serving cell. Therefore, there will be multiple neighboring cell frequencies, and thus each neighboring cell frequency will have its corresponding enabling threshold.

The operator can set the frequency priority of the adjacent cell according to the network strategy or the service strategy. The high priority frequency is the frequency of the priority access, and the operator realizes the priority access by setting a higher start-up threshold for the frequency. For example, in the case that the received power of the current service signal is not reduced much, that is, the condition of the start-up threshold is met, the measurement of the neighboring cell is started, so that the handover process is easier to start, and the terminal is easier to handover to the high-priority frequency. Therefore, it can be seen that the start-up thresholds corresponding to the frequencies of the neighboring cells issued in the broadcast message are different, and the example of the start-up thresholds corresponding to the frequencies of the neighboring cells in the handover procedure is similar to that in table two.

S502: and acquiring 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 the frequency and the departure time, which are collected by the procedure of storing the anchor frequency information table by the terminal.

S503: and adjusting the start-up threshold value corresponding to each frequency to be measured when the terminal switches according to the anchor frequency information table and the received broadcast message, and determining a switching offset parameter according to the anchor frequency information table.

Here, the criterion for adjusting the measurement start threshold is to increase the priority of the anchor frequency, so that the terminal is easier to switch to the anchor frequency of the anchor cell, and thus, when the measurement start threshold is adjusted, the measurement start threshold corresponding to the anchor frequency is increased. Specific criteria for adjustment include: the anchor frequency has a higher priority than the non-anchor frequency. Determining the 'freshness' of the anchor frequency according to the difference value between the leaving time and the current time in the anchor frequency, wherein the closer leaving time indicates that the anchor frequency is fresher; the higher the freshness the higher the anchor frequency, the higher its threshold value of enablement. If one or more frequencies of the adjacent cell frequency sent by the original broadcast message are in the anchor frequency list of the terminal, setting the priority of the frequencies in the anchor frequency list according to the freshness of the anchor frequency.

The following is illustrated by way of example:

the criterion for adjusting the measurement starting threshold value is to increase the priority of the anchor frequency, so that the terminal can more easily reselect to the anchor frequency of the anchor cell. Therefore, when the start-up threshold is adjusted, the start-up threshold corresponding to the anchor frequency is increased. Specific criteria for adjustment include: the anchor frequency has a higher priority than the non-anchor frequency. In the anchor frequency, determining the freshness of the anchor frequency according to the difference between the leaving time and the current time, wherein the closer leaving time indicates that the anchor frequency is fresher; the higher the freshness the higher the anchor frequency, the higher its threshold value of enablement. If one or more frequencies are in the anchor point frequency list of the terminal in the adjacent cell frequency sent by the original broadcast message, setting the priority of the frequencies in the anchor point frequency list according to the anchor point frequency and the freshness.

The following is illustrated by way of example:

the frequency of the neighboring cell sent by the broadcast message corresponds to the start-up threshold as in table two, and the anchor point frequency information table queried in the terminal anchor point frequency list is as in table three in the above embodiments. In Table three, leave f _m1 The time of the cell in which the frequency is located is closest to the current time in the list, and therefore its priority is highest, f _m2 Then, if f is exactly ₃ ＝f _m1 That is, if there is a frequency in the frequency of the neighboring cell sent by broadcasting and the frequency of the anchor point in the storage module are the same, the adjusted result is as shown in table four in the above embodiment.

The target of the handover offset parameter is to make the terminal easier to switch to the anchor frequency, and to make the terminal reside on the anchor frequency as much as possible to connect with the anchor cell, so the offset value is set to reduce the threshold value of the frequency switched to the anchor, that is, the handover offset parameter is used to adjust the handover threshold value issued by the broadcast message. For anchor frequencies with high "freshness", the switching threshold is lower.

S504: when the terminal in the connection state detects that the signal receiving power of the current service cell is reduced below a certain starting threshold, the terminal measures the receiving power of the frequency corresponding to the starting threshold. And performing switching judgment according to the measured value of the received power, the switching threshold value and the switching offset parameter.

During handover, the RSRP of a broadcast channel or a pilot channel is typically measured.

S505: if the switching criterion is satisfied, the process proceeds to S506. If the switching criterion is not satisfied, return to before S504. And triggering the switching judgment again when the terminal detects that the signal receiving power of the current service cell is reduced below a certain starting threshold.

S506: the source serving cell detects whether the target cell corresponding to the frequency meeting the handover criterion in S505 is on the neighbor list. If it is in the list, the process proceeds to S508. If not, the process proceeds to S507.

S507: and adding the target cell into a neighbor cell list, and acquiring the information of the base station of the target cell. And establishing the X2 interface according to the self-establishment condition setting of the X2 interface.

S508: the terminal performs handover.

The new anchor point switching method provided by the embodiment of the invention 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 connection state, and configures the anchor point cell corresponding to the anchor point frequency which is not configured as the neighbor cell into the neighbor cell relation under the condition that the anchor point cell is determined as the target cell, thereby enabling the terminal to quickly switch to the anchor point frequency and improving the switching efficiency of the 5G NSA terminal.
