Description
Technical Field
The present invention relates to the field of communications, and in particular, to a network paging method and apparatus based on a 5G system.
Background
In a Fifth Generation mobile communication (5G) system independent networking (SA) architecture, a User Equipment (UE) may enter a deactivated (RRC _ INACTIVE) state, when the last serving base station where the UE is located receives downlink data or signaling sent by the 5G core Network, the last serving base station may initiate a Network Paging (RAN Paging) to a cell within the coverage area, when the cell is the cell of the adjacent base station outside the coverage of the last service base station, the last service base station will first send the RAN Paging message to the adjacent base station through the Xn port, then, the RAN Paging message is sent to the cell of the neighbor base station, if the UE successfully acquires the RAN Paging message, the UE can enter a recovery process in an RRC _ INACTIVE state, that is, the UE transitions from the RRC _ INACTIVE state to the CONNECTED (RRC _ CONNECTED) state, and performs a subsequent processing procedure of downlink data or signaling.
However, since air interface resources are limited, it is impossible for the base station to send the RAN Paging message to all neighboring cells at the same time. In addition, from the prior art, the last serving base station may select a cell having the same Public Land Mobile Network (PLMN) and Network location Area Code (RANAC) as the cell of the last serving base station to send the RAN Paging message. And if the selected adjacent cell belongs to N different base stations, sending a RAN Paging message to the N base stations through an Xn port according to the configuration sequence of the adjacent cell.
It can be seen that, in the prior art, it cannot be determined that a cell that needs to send a RAN Paging message is only able to send the RAN Paging message to all cells having the same PLMN and RANAC, and when there are many cells under RANAC, the serving base station needs to send many Xn Paging messages, and there are many RAN Paging messages sent over the air, but the Paging efficiency is low, and the air Paging resources of the base station cannot be efficiently used.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the present invention, referring to fig. 1, before sending a RAN Paging message to a cell, a first base station needs to evaluate a priority of the cell, and a process of evaluating the priority of the cell is as follows:
step 100: the first base station counts the times of switching request and ping-pong switching times of respective adjacent cells of each cell, and calculates the effective switching times according to the switching request times and ping-pong switching times.
Specifically, in the embodiment of the present invention, in an SA architecture of a 5G system, a UE is in an RRC _ INACTIVE state, a base station served by the UE at the last needs to count Xn handover request times and Xn ping-pong handover times of respective neighboring cells of a cell in which the UE is located in the base station, and further, according to the Xn handover request times and the Xn ping-pong handover times, an effective handover time M of the respective neighboring cells of the cell in which the UE is located can be calculated, that is, M ═ Xn handover request times — Xn handover times, where a period of time for the statistics may be one day, one hour, and the like.
The actual adjacent cells are determined according to the network planning during actual networking, and are not limited to the cells directly adjacent to each other in the geographic position. Particularly, after the RRC _ INACTIVE state is introduced, the neighboring cells need to be determined according to the RAN Area, that is, all cells in the RAN Area are neighboring cells to each other.
For example, the neighboring cells of the cell 1 in which the UE is located are the cell 5, the cell 6, and the cell 7, and the base station counts the Xn handover request times and the Xn ping-pong handover times of the cell 5, the cell 6, and the cell 7 in one day to be 2 and 0, 6 and 1, 5, and 2, respectively, so that the effective handover times M of the cell 5, the cell 6, and the cell 7 are 2, 5, and 3, respectively.
Step 101: and the first base station counts the times of user recovery processes of respective adjacent cells of the cells.
Specifically, in the embodiment of the present invention, after counting the Xn handover REQUEST times and the Xn ping-pong handover times, the base station may count the times that the respective neighboring cells of each cell send the user CONTEXT REQUEST (RETRIEVE UE CONTEXT REQUEST) to the base station within a period of time, that is, the number R of times of the user recovery process, where the statistical time of the number R of times of the user recovery process is consistent with the statistical time of the effective handover times M, that is, the period of time may be one day, one hour, and the like.
Step 102: and the first base station evaluates the respective adjacent cells of the cells according to the effective switching times and the user recovery process times.
Specifically, in this embodiment of the present invention, after counting the number M of effective handovers and the number R of user recovery processes, the first base station may periodically evaluate each neighboring cell of each cell where the UE is located according to a value of (M + R × u), that is, the value of (M + R × u) may be updated, and the higher the value of (M + R × u), the higher the cell priority is, where u is a correction factor, and the priority for sending the RETRIEVE UE CONTEXT REQUEST by the neighboring cell may be increased by increasing the value of u.
In the embodiment of the present invention, after evaluating the priority of each neighboring cell of each cell, the first base station may initiate a network paging procedure by using the evaluation result of the priority, as shown in fig. 2, the network paging procedure is as follows:
step 200: the first base station determines a cell set to be processed, judges whether a cell to be paged exists in the cell set to be processed according to first identification information preset by a corresponding cell, and obtains a first judgment result.
Specifically, in the embodiment of the present invention, a RAN paging is initiated at a first base station, a cell in a local jurisdiction range is selected from a neighbor cell list preset by the first base station according to a Network location Area identifier (RAN Area ID), and after neighbor cells in jurisdictions of other peripheral base stations are determined, the selected cells may be sorted according to the size of priority, so as to determine a to-be-processed cell set, and whether a to-be-paged cell exists in the to-be-processed cell set is determined according to the preset RAN Area ID corresponding to each to-be-processed cell, so as to obtain a first determination result.
For example, the set of cells to be processed may be a list of cells to be processed, when the first base station selects cells in the local jurisdiction as cell 2, cell 3, cell 4, and cell 5, it counts the effective handover times M corresponding to each cell within 1 day time to be 3, 5, 2, and 6, the user recovery process times R corresponding to each cell are 2, 3, 1, and 4, assuming that the correction factor u corresponding to each cell is 3, the value of (M + R u) corresponding to each cell is calculated by a formula to be 9, 14, 5, and 18, then the cell 2, cell 3, cell 4, and cell 5 are sorted from high to low according to the calculated value of (M + R u), the sorting result is cell 5, cell 3, cell 2, and cell 4, the list of cells to be processed is cell 5, cell 3, cell 2, and cell 4, that is, the priority order of each cell in the pending cell set is cell 5, cell 3, cell 2, and cell 4.
Step 201: and when the first base station determines that the cells to be paged exist in the cell set to be processed according to the first judgment result, selecting the first N cells with the highest priority from the cells to be paged.
Specifically, in the embodiment of the present invention, when the first base station determines that there is a cell to be paged in the to-be-processed cell set according to the first determination result, the first N cells with the highest priority are selected from the to-be-paged cells in the to-be-processed cell set according to the processing capability of the first base station or the configuration of the management station.
For example, when the first base station determines that the cells to be paged exist in the cell set to be processed are cell 2, cell 3, cell 4, and cell 5, respectively, according to the first determination result, the first base station selects the first 3 cells with the highest priority from the cell 2, cell 3, cell 4, and cell 5 to be paged according to the priority order of the cell 5, cell 3, cell 2, and cell 4, that is, according to the priority order of the cell 5, cell 3, cell 4, and knows that the first 3 cells with the highest priority from the cell 2, cell 3, cell 4, and cell 5 are cell 5, cell 3, and cell 2, respectively, then selects the first 3 cells with the highest priority from the cell 2, cell 3, cell 4, and cell 5 to be paged as cell 5, cell 3, and cell 2, respectively.
Step 202: and the first base station further judges the base stations to which the former N cells belong according to second identification information preset corresponding to the cells to obtain a second judgment result.
Specifically, in the embodiment of the present invention, the first base station determines that there is a Cell to be paged in the to-be-processed Cell set, and after selecting the first N cells with the highest priority, determines, according to a preset Cell Identification (Cell Identification, Cell ID) corresponding to the first N cells, a base station to which the first N cells belong, and obtains a second determination result.
Step 203: and when the first base station determines that the former N cells belong to the second base station according to the second judgment result, the first base station sends the paging message to the former N cells through an Xn port.
Specifically, in the embodiment of the present invention, when the first base station determines that the first N cells all belong to the second base station according to the preset Cell IDs corresponding to the first N cells, the first base station sends a RAN Paging message to the base station only through the Xn port. For example, when the first N cells belong to the base station 2, a RAN Paging message is sent to the first N cells under the base station 2 through the Xn port.
In the embodiment of the present invention, referring to fig. 3, after evaluating the priority of each neighboring cell of each cell, the first base station may initiate a network paging procedure by using the evaluation result of the priority, where the detailed network paging procedure is as follows:
step 300: and the first base station selects the cells in the local jurisdiction range from the neighbor cell list according to the first identification information, and determines the neighbor cells in the jurisdiction ranges of other peripheral base stations.
Specifically, in the embodiment of the present invention, after performing priority evaluation on each neighboring cell of each cell according to the value of (M + R × u), the first base station initiates network paging, selects a cell in the local jurisdiction from a neighboring cell list preset by the first base station according to the RAN Area ID, and determines neighboring cells in jurisdictions of other surrounding base stations.
Step 301: and the first base station sorts the cells according to the priority and determines a cell set to be processed.
Specifically, in the embodiment of the present invention, after determining the cells in the local jurisdiction and determining the neighboring cells in the jurisdiction of other surrounding base stations, the first base station may first sort the selected cells according to the priority, so as to form a set of cells to be processed.
For example, the set of cells to be processed may be a list of cells to be processed, when the first base station selects cells requiring local jurisdiction as cell 3, cell 4, cell 5, cell 6, and cell 7, it counts the effective handover times M corresponding to each cell within 1 day time to be 2, 5, 3, 1, and 4, the user recovery process times R corresponding to each cell are 2, 3, 1, 2, and 2, assuming that the correction factors u corresponding to each cell are all 3, the values of (M + R × u) corresponding to each cell are calculated by a formula to be 8, 14, 6, 7, and 10, then the values of (M + R × u) corresponding to each cell are sorted from high to low according to the calculated values of (M + R × u), and the sorting result is the list of cells 6, 4, 7, 5, and 3, and 6, Cell 4, cell 7, cell 5 and cell 3, that is, the priority order of each cell in the pending cell set is cell 6, cell 4, cell 7, cell 5 and cell 3.
Step 302: the first base station judges whether a cell to be paged exists in the cell set to be processed according to first identification information preset in the corresponding cell, and obtains a first judgment result, if so, step 303 is executed, otherwise, step 310 is executed.
Specifically, in the embodiment of the present invention, after determining the set of cells to be processed, the first base station may determine, according to the preset RAN Area ID corresponding to each cell to be processed, whether a cell to be paged exists in the set of cells to be processed, to obtain a first determination result, if a cell to be paged exists, perform step 303, and if a cell to be paged does not exist, perform step 310.
Step 303: and when the first base station determines that the cells to be paged exist in the cell set to be processed according to the first judgment result, selecting the first N cells with the highest priority from the cells to be paged.
Specifically, in the embodiment of the present invention, when the first base station determines that there is a cell to be paged in the to-be-processed cell set according to the first determination result, the first N cells with the highest priority are selected from the to-be-paged cells in the to-be-processed cell set according to the processing capability of the first base station or the configuration of the management station.
For example, when the first base station determines that the cells to be paged exist in the cell set to be processed respectively as the cell 3, the cell 4, the cell 5, the cell 6 and the cell 7 according to the first determination result, the first base station selects the first 4 cells with the highest priority from the cell 3, the cell 4, the cell 7, the cell 5 and the cell 7 to be paged according to the priority order of the cell 6, the cell 4, the cell 7, the cell 5 and the cell 3, and knows that the first 4 cells with the highest priority from the cell 3, the cell 4, the cell 5, the cell 6 and the cell 7 are respectively the cell 6, the cell 4, the cell 7 and the cell 5, and selects the first 4 cells with the highest priority from the cell 3, the cell 4, the cell 5, the cell 6 and the cell 7 to be paged respectively as the cell 6, Cell, cell 7, cell 5.
Step 304: and the first base station judges whether the base stations to which the first N cells belong to the first base station according to second identification information preset by the corresponding cell, a second judgment result is obtained, if the base stations belong to the first base station, step 305 is executed, and if the base stations do not belong to the first base station, step 306 is executed.
Specifically, in the embodiment of the present invention, the first base station determines that there are cells to be paged in the to-be-processed Cell set, and after selecting the first N cells with the highest priority, determines whether the first N cells all belong to the first base station according to preset Cell IDs corresponding to the first N cells, to obtain a second determination result, if both the first N cells all belong to the first base station, step 305 is executed, and if both the first N cells all belong to the second base station, step 306 is executed.
Step 305: and when the first base station determines that the former N cells belong to the first base station according to the second judgment result, the first base station directly sends the RAN Paging message to the former N cells.
Specifically, in the embodiment of the present invention, when the first base station determines that the first N cells are cells in the first base station according to preset Cell IDs corresponding to the first N cells, the first base station directly sends a RAN Paging message to the first N cells in the first base station, that is, directly initiates Paging to the first N cells.
Step 306: and when the first base station determines that the former N cells belong to the second base station according to the second judgment result, the first base station sends the RAN Paging message to the former N cells through an Xn port.
Specifically, in the embodiment of the present invention, when the first base station determines that the first N cells all belong to the second base station according to the preset Cell IDs corresponding to the first N cells, for example, the first base station may be N cells under the base station 1, or may be N cells under the base stations 1 and 2, and then sends the RAN Paging message to the first N cells through the Xn port. And if the selected first N cells belong to the same second base station, sending a RAN Paging message to the second base station only through an Xn port. For example, when the first N cells belong to the base station 1, a RAN Paging message is sent to the first N cells under the base station 1 through the Xn port.
Step 307: the first base station deletes the cell which has sent the RAN Paging message from the set of cells to be processed.
Specifically, in this embodiment of the present invention, the first base station directly sends the RAN Paging message to the first N cells according to the second determination result, or deletes the cell that sends the RAN Paging message from the to-be-processed cell set when sending the RAN Paging message to the second base station of the first N cells through the Xn port.
Step 308: the first base station starts a timer T and judges whether the timer T is overtime according to a preset time threshold, if yes, the step 302 is returned, otherwise, the step 309 is executed.
Specifically, in the embodiment of the present invention, when the first base station initiates Paging to the first N cells and deletes a cell that sends a RAN Paging message from the set of cells to be processed, a timer T is started, and whether the timer T is overtime is determined according to a preset time threshold, if the timer T is overtime, the timer T is restarted, and step 302 is returned, and if the timer T is not overtime, step 309 is executed.
For example, the preset time threshold is 500ms, when the timer T is 510ms, the first base station determines that the timer T is greater than 500ms, determines that the timer T is overtime, restarts the timer T, that is, sets the timer T to 0, and returns to step 302, to determine whether there is a cell to be paged in the cell set to be processed again, so as to obtain a first determination result. When the timer T is 350ms, the first base station determines that the timer T is less than 500ms, determines that the timer T is not overtime, and executes step 309.
Step 309: and when the first base station receives a user CONTEXT RESPONSE (RETRIEVE UE CONTEXT RESPONSE) message returned by the second base station, stopping the timer T.
Specifically, in the embodiment of the present invention, when the cell that sends the RAN Paging message is a cell in the first base station, the first base station determines, according to a preset time threshold, that the timer T is not timed out, and then determines that the RAN Paging message has been sent to the cell, and further initiates Paging to the UE in the cell, and triggers a recovery process of the UE in an RRC _ INACTIVE state, or starts the timer, and determines that the timer is not timed out according to the preset time threshold, but receives a RETRIEVE UE ext RESPONSE message returned by the second base station, determines that the Paging message is successfully sent to the cell, and stops the timer T.
Step 310: the first base station determines that the procedure is finished.
Specifically, in the embodiment of the present invention, after determining the to-be-processed cell set, when the first base station determines, according to the first determination result, that there is no to-be-paged cell in the to-be-processed cell set, it determines that the RAN Paging establishment procedure is ended, or the first base station receives a user context response message returned by the second base station, determines that the Paging message is successfully sent to the cell, stops the timer T, and determines that the network Paging procedure is ended.
