Description

Autonomous switching and switching processing method and device for terminal in cluster group

Technical field

The present invention relates to the field of communications, and in particular, to a method and apparatus for autonomous handover and handover processing of a terminal in a cluster group.

Background technique

The cluster is a one-stop system. After the cluster group call is established, if the user in the group listening state is located at the cell boundary, when the user detects that the neighbor cell signal meets the autonomous handover threshold, and the target cell has already been the group call A downlink broadcast bearer is set up, and the user equipment (also referred to as a user equipment, referred to as a UE) switches to the target cell by itself, and the handover does not require the participation of the base station. Since the base station is not aware of this process, it causes some problems.

The problems encountered in dynamic scheduling during the autonomous handover process are as follows:

As shown in Figure 1, it is assumed that the group call establishes a downlink broadcast bearer on the cell (CELL) 1, CELL2, the users in CELL1 are concentrated in the center of the cell, and CELL1 uses Modulation and Coding Scheme (MCS). If the user equipment UE2 in CELL2 is at the cell boundary, the MCS is equal to 4 for scheduling, and the UE2 moves to the CELL1 side. When the autonomous handover condition is met, the UE2 performs autonomous handover. After switching to CELL1, the CELL1 downlink broadcast bearer is used. If the MCS is equal to 10, the UE2 needs to report the downlink broadcast bearer packet for a period of time because the MCS is too different. The UE2 needs to report the channel quality indicator (CQI). CELL1 downgrades MCS. The CQI report takes about 40 milliseconds. There will be two voice frames in 40 milliseconds. If the MCS is down, there will be at least three consecutive voice frame errors. If a terminal frequently switches at the boundary position, it will appear. A poorly experienced voice experience may be worse for a video experience.

Problems encountered in semi-static scheduling during autonomous switching:

When the MCS changes during the semi-persistent scheduling, the MCS value is sent to the air interface through the downlink control information (Downlink Control Information, DCI for short). The latest MCS value needs to be sent to the neighboring cell in real time, and the neighboring cell needs to be configured through the group call. The message is sent to the terminal in real time to ensure that the user in the group listening state can correctly demodulate the downlink broadcast bearer in the target cell after the autonomous handover. Because the MCS changes frequently, sometimes even 100ms changes once. Such frequent changes will lead to neighboring zone update. The amount of messages and the number of air interface group call configuration messages is huge, which affects the processing capability of the base station. There is no effective solution to the above problems in the related art.

Summary of the invention

The present invention provides a cluster group in the related art, because the base station (ie, the network side) cannot know the user experience difference caused by the terminal autonomous handover, and the technical information of the air interface configuration information caused by the frequent autonomous handover is large. The autonomous switching, switching processing method and device of the terminal solve at least the above technical problems.

According to an embodiment of the present invention, a method for autonomous handover of a terminal in a cluster group is provided, including: the terminal in the listening state reports a measurement report for the target cell to the network side before the autonomous handover, and the measurement report carries useful information. The target cell measurement information for determining the handover of the terminal is determined; after the terminal reports the measurement report, the terminal autonomously switches to the target cell.

Preferably, after the terminal reports the measurement report, the terminal switches to the target cell, where the terminal starts the first timer when reporting the measurement report; When the predetermined time is up, the terminal is triggered to switch to the target cell, where the first predetermined time is not greater than a time required for the target cell to perform corresponding adjustment for the terminal handover.

Preferably, the target cell performs corresponding adjustment for the terminal handover, including at least one of: reducing the value of the MCS of the group where the terminal is located to a preset value; and when the current bearer of the group where the terminal is located is a semi-persistent scheduling When the current bearer is changed to dynamic scheduling.

Preferably, when the current bearer is changed to the dynamic scheduling, the method further includes: starting a second timer, and adjusting, by the dynamic scheduling, the scheduling mode of the current bearer to a half when the second timer exceeds the second predetermined time Static scheduling, wherein the second predetermined time is not less than the first predetermined time.

Preferably, reporting the measurement report for the target cell to the network side comprises: reporting the measurement report by using a Radio Resource Control (RRC) connection between the terminal and the network side.

Preferably, after the handover to the target cell, the method further includes: the terminal reporting CQI information to the network side.

According to still another embodiment of the present invention, a method for autonomous handover processing of a terminal in a cluster group is provided, including: the network side device receives a measurement report from the terminal for the target cell, where the terminal is in a listening state, and the measurement report And carrying the target cell measurement information for determining that the terminal performs the handover; the network side device notifying the target cell that the group where the terminal is located needs to perform autonomous handover.

When the current bearer of the group in which the terminal is located is a semi-persistent scheduling, the network side device changes the current bearer to dynamic scheduling.

According to still another embodiment of the present invention, an autonomous switching device for a terminal in a cluster group is provided, and is applied to the terminal, and includes: a reporting module, configured to: before the autonomous switching of the terminal in the listening state, to the network side The measurement report for the target cell is carried, the measurement report carries the target cell measurement information for determining the handover of the terminal, and the handover module is configured to, after reporting the measurement report, the source cell autonomously switches to the target cell.

According to the embodiment of the present invention, after the terminal performs autonomous handover, the measurement report of the target cell is reported to the network side, and then the handover is performed, and the related technology is solved, because the base station (ie, the network side) cannot learn the terminal autonomous handover.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

FIG. 2 is a flowchart of a method for autonomous handover of a terminal in a cluster group according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following processing steps:

In step S202, the terminal in the listening state reports the measurement report for the target cell to the network side before the autonomous handover, and the measurement report carries the target cell measurement information used to determine the handover of the terminal.

Step S204, after the terminal reports the measurement report, the terminal autonomously switches to the target cell.

Through the foregoing processing steps, the terminal reports the measurement report to the network side before the autonomous handover. Therefore, the user experience that the base station (ie, the network side) cannot learn the terminal autonomous handover is poor, and the air interface configuration caused by frequent autonomous handover is solved. The technical problem is such that the amount of information is large, so that the network side can participate in the autonomous handover of the terminal, which reduces the frequent handover of the terminal and the amount of air interface configuration messages, and improves the user experience in the autonomous handover process.

In a preferred embodiment, the network side may be represented by a source cell, or a base station where the source cell is located, or a base station to which the source cell and the target cell belong.

In order to ensure the success rate of the handover, the step S204 may be implemented by: when the terminal reports the foregoing measurement report, the first timer is started; when the timer exceeds the first predetermined time, the terminal is triggered to switch to the target cell, where the first The predetermined time is not greater than the time required for the target cell to adjust for the terminal handover. In this way, it can be ensured that the target cell has prepared for the handover and improves the handover success rate.

In order to better understand the above implementation process, the following detailed description is combined with a preferred implementation process:

When the audible state terminal of the group does not establish an RRC connection with the base station, the measurement report is reported on the source cell before the autonomous handover, and the measurement report needs to carry the RSRP of the target cell (Reference Signal Receiving). The power, the reference signal receiving power, the current cell ID, and the like, the terminal starts a timer when reporting the measurement report message, and then automatically switches to the target cell after the timer expires.

When the listening state terminal of the group and the LTE (Long Term Evolution) are concurrently connected, the RRC connection is established with the base station, and a measurement report is reported to the source cell to perform the handover request before the autonomous handover.

The source cell distinguishes the measurement report of the handover by using the content of the measurement report reported by the terminal, and if yes, sends the measurement report to the target cell, the source cell receives the measurement report reported by the terminal, and if it is the measurement report of the handover, sends the autonomous handover message to the target cell. After receiving the autonomous handover message sent by the source cell, the target cell notifies the target cell to lower the MCS value of the group to a preset value to meet the requirements of the edge terminal.

In this embodiment, the target cell performs corresponding adjustment for the terminal handover, including but not limited to at least one of the following: 1. The value of the MCS of the group in which the terminal is located is reduced to a preset value (see the foregoing implementation process for details); When the current bearer of the group in which the terminal is located is semi-persistent scheduling, the current bearer is changed to dynamic scheduling. When the current bearer is changed to the dynamic scheduling, the following process may be further included: the second timer is started, and when the second timer exceeds the second predetermined time, the current bearer scheduling mode is adjusted from dynamic scheduling to Semi-static scheduling, wherein the second predetermined time is not less than the first predetermined time. For the second adjustment method, in a preferred embodiment, the following implementation process can be performed:

If the current group's bearer is a semi-persistent scheduling, the semi-persistent scheduling is changed to dynamic scheduling. In the dynamic scheduling process, if the semi-static scheduling of the group is active or reactivated, the group needs to be first Deactivate and start a timer to maintain dynamic scheduling until the timer expires. After the timeout, semi-static scheduling is performed when semi-persistent scheduling is satisfied. The duration of the timer needs to be longer than the waiting period for reporting the measurement report before the autonomous handover of the terminal, so as to ensure that the terminal is still dynamically scheduled when it switches to the target cell autonomously.

In this embodiment, the implementation of the step S202 is various. For example, the measurement report may be reported by using a radio resource control connection between the terminal and the network side.

To ensure the stability of the terminal after handover to the target cell, the terminal may report channel quality indication (CQI) information to the network side after switching to the target cell. Certainly, in a preferred implementation process, the foregoing processing steps can also ensure that the source cell cannot receive the measurement report reported by the UE, and can also solve the user experience problem after the autonomous handover to the target cell.

In order to implement the foregoing method, in the embodiment, autonomous switching device of the terminal in the cluster group is further applied to the terminal in the listening state. As shown in FIG. 3, the device includes: a reporting module 30, which is set to be in the terminal. Before performing the autonomous handover, the measurement report for the target cell is reported to the network side, and the measurement report is carried to determine the end The target cell measurement information is switched, and the switching module 32 is connected to the reporting module 30, and is configured to automatically switch to the target cell by the source cell after reporting the measurement report.

It should be noted that each of the foregoing modular modules may be implemented by software or hardware. For the latter, the foregoing may be implemented by, but not limited to, the reporting module 30 is located in the first processor, and the switching module 32 is located in the second In the processor, the reporting module 30 and the switching module 32 are located in the same processor.

In one embodiment, the flow on the network side is also improved. FIG. 4 is a flowchart of a method for autonomous handover processing of a terminal in a cluster group according to an embodiment of the present invention. As shown in FIG. 4, the method includes the following processing steps:

Step S402, the network side device receives the measurement report from the terminal for the target cell, where the terminal is in the listening state, and the measurement report carries the target cell measurement information used to determine the terminal to perform the handover;

Step S404, the network side device notifies that the group where the target cell terminal is located needs to perform autonomous handover.

After the step S404, that is, the network side device notifies the target cell that the group in which the terminal is located needs to perform the autonomous handover, the network side device further includes at least one of the following: the network side device lowers the value of the MCS of the group in which the terminal is located in the target cell. To the preset value; when the current bearer of the group in which the terminal is located is a semi-persistent scheduling, the network side device changes the current bearer to dynamic scheduling.

In this embodiment, a device for autonomous switching of a terminal in a cluster group is also provided, which is applied to a network side device, and the device is used to implement the foregoing method. As shown in FIG. 5, the device includes:

The receiving module 50 is configured to receive a measurement report from the terminal for the target cell, where the terminal is in a listening state, and the measurement report carries target cell measurement information used to determine the handover of the terminal;

The notification module 52 is connected to the receiving module 50 and configured to notify the group in which the target cell terminal is located to perform autonomous handover.

In order to better understand the above embodiments, the following detailed description will be given in conjunction with the preferred embodiments.

Example 1

When the listening user does not establish an RRC connection with the base station, the process of autonomously switching the MCS message in the station is as shown in FIG. 6:

(1) The user in the listening state measures the edge of the source cell, detects that the neighboring cell signal meets the autonomous handover threshold, and knows that the target cell has established a downlink broadcast bearer for the group call by using the group call configuration message;

(2) Since the listening user does not establish an RRC connection, the RRC connection may be established first, the measurement report is sent through the RRC connection (the measurement report may also be sent by other means), and the timer t1 is started;

(3) The base station source cell receives the measurement report, and the source cell knows that the target cell establishes a broadcast bearer, and notifies the target cell that the group has autonomous handover;

(4) After receiving the message, the target cell reduces the group MCS to a threshold as much as possible, and satisfies the requirement that the autonomous handover terminal is at the cell edge;

(5) If the group is semi-persistent scheduling, start timer t2, perform dynamic scheduling in timer t2; t2 timer expires to resume semi-static scheduling;

(6) The t1 timer expires, and the UE autonomously switches to the target cell;

(7) After autonomous handover to the target cell, the UE reports a measurement report containing CQI information;

(8) After receiving the measurement report of the CQI information, the target cell adjusts the MCS value of the actual scheduling according to the received CQI information; the process ends.

Based on the above process, one implementation of this embodiment is as follows:

(1) CELL1 and CELL2 exist in the same base station. The users in group A are distributed in CELL1 and CELL2. Currently, the group call of group A is already in the call state. Now the user A of group A is moving from CELL1 to CELL2; For a, CELL1 is the source cell and CELL2 is the target cell.

(2) Since a is only in the listening state, the RRC connection relationship is not established with the base station. When the CELL1 edge is reached, the neighboring area information that the user a receives the base station group call configuration information includes CELL2, and determines that the autonomous handover procedure can be initiated.

(3) Listening to the user a sends a measurement report to CELL1. Since the listening user does not establish an RRC connection, the RRC connection can be established first, and the measurement report can be sent through the RRC connection (the measurement report can also be sent by other means), and the user a starts the timer t1. 50ms;

(4) The test report includes the target cell CELL2 that listens to user a and autonomously switches. Since CELL1 and CELL2 are in the same base station, CELL1 can directly send the autonomous handover request message of group A to CELL2, indicating that CELL1 has listened to user a. Switch to CELL2 autonomously;

(5) CELL2 receives the group A autonomous handover request message sent by CELL1, and reduces the scheduling MCS of group A to 4 as much as possible, and satisfies the requirement that the autonomous handover terminal is at the cell edge;

(6) If the group A is semi-statically scheduled in CELL2, the timer t2 is started for 100 ms and dynamic scheduling is performed; the timer expires to resume semi-persistent scheduling, and the purpose is to ensure that the listening user a autonomously switches to the target cell without packet loss;

(7) After listening to the t1 timing of the user a, the mode is autonomously switched to the target cell CELL2, the target cell CELL2 is switched, and the CQI is reported once. The reporting mode is similar to the reporting method.

(8) CELL2 receives the CQI information reported by the user a, and can re-adjust the MCS information scheduled by the group A to meet the needs of the actual scheduling.

Example 2

When the listening user does not establish an RRC connection with the base station, the station automatically switches to adjust the MCS message flow, as shown in Figure 7:

(3) If it is an inter-station handover, the source cell sends an autonomous handover request message to the core network;

(4) After receiving the autonomous handover request message, the core network forwards the message to the target cell;

(5) After receiving the message, the target cell reduces the group MCS to a threshold as much as possible, and satisfies the requirement that the autonomous handover terminal is at the cell edge;

(6) If the group is semi-persistent scheduling, start timer t2, perform dynamic scheduling in timer t2; t2 timer expires to resume semi-static scheduling;

(7) The t1 timer expires, and the UE automatically switches to the target cell;

(8) After autonomously switching to the target cell, the UE reports a measurement report containing CQI information;

(9) After receiving the measurement report of the CQI information, the target cell adjusts the MCS value of the actual scheduling according to the received CQI information; the process ends.

(1) CELL1 and CELL2 exist in two different base stations, and the users in group A are distributed in CELL1 and CELL2. Currently, the group call of group A is already in the call state, and now user A of group A is moving from CELL1. To CELL2; for a, CELL1 is the source cell and CELL2 is the target cell.

(3) Listening to the user a sends a measurement report to CELL1. Since the listening user does not establish an RRC connection, the RRC connection can be established first, and the measurement report can be sent through the RRC connection (the measurement report can also be sent by other means), and the user a starts the timer t1. 80ms;

(4) The test report includes the user A, the target cell CELL2 that is autonomously switched. Since CELL1 and CELL2 are not in the same base station, CELL1 needs to send the group A's autonomous handover request message to the core network, and the core network puts the group A. The autonomous switching message is sent to CELL2, indicating that CELL1 has listened to user a to switch to CELL2 autonomously;

(5) CELL2 receives the group A autonomous handover request message sent by CELL1, and reduces the scheduling MCS of group A to 3 as much as possible, and satisfies the requirement that the autonomous handover terminal is at the cell edge;

(6) If the group A is semi-statically scheduled in CELL2, the timer t2 is started for 150 ms and dynamic scheduling is performed; the timer expires to resume semi-persistent scheduling, and the purpose is to ensure that the listening user a autonomously switches to the target cell without packet loss;

Example 3

When the user establishes an RRC connection with the base station, the process of autonomously switching and adjusting the MCS message in the station is as shown in FIG. 8:

(2) Since the listening user has established an RRC connection, the measurement report can be directly sent through the RRC connection, and the timer t1 is started;

(6) The t1 timer expires, and the UE autonomously switches to the target cell;

(1) CELL1 and CELL2 exist in the same base station. The users in group A are distributed in CELL1 and CELL2. Currently, the group call of group A is already in the call state. Now the user A of group A is moving from CELL1 to CELL2, listening user a, in addition to the information sent by listening group A, is still uploading pictures on Weibo, so it establishes RRC connection relationship with base station; for a, CELL1 is the source cell and CELL2 is the target cell.

(2) Since a is only in the listening state, when the CELL1 edge is reached, the neighboring area information that the user a receives the base station group call configuration information includes CELL2, and it is determined that the autonomous handover procedure can be initiated;

(3) Listening user a can directly send a measurement report to CELL1 because it has established an RRC connection relationship with the base station, and listen to user a to start timer t1 for 50 ms;

(7) After listening to the t1 timing of the user a, the autonomous handover to the target cell CELL2, the handover to the target cell CELL2, the service with the RRC also switches to the target cell, and the CQI is reported once through the RRC connection;

Example 4

When there is an RRC connection, the process of autonomous switching between stations to adjust the MCS message is shown in Figure 9:

(7) The t1 timer expires, and the UE automatically switches to the target cell;

(1) CELL1 and CELL2 exist in two different base stations, and the users in group A are distributed in CELL1 and CELL2. Currently, the group call of group A is already in the call state, and now user A of group A is moving from CELL1. To CELL2, the user a is listening to the webpage in addition to the information sent by the listening group A, so the RRC connection relationship is established with the base station; for a, CELL1 is the source cell and CELL2 is the target cell.

(3) Listening user a can directly send a measurement report to CELL1 because it has established an RRC connection relationship with the base station, and listen to user a to start timer t1 to be 80 ms;
