Detailed Description
In order to make the technical field better understand the scheme of the embodiment of the invention, the following detailed description of the embodiment of the invention is provided in conjunction with the accompanying drawings and the implementation mode.
Example 1
Referring to fig. 1, a flowchart of embodiment 1 of a terminal-side movement control method according to the present invention is shown, where the method may include:
s101, a terminal sends a neighbor cell signal measurement result to a resident cell home base station, so that the resident cell home base station selects a neighbor cell as a target cell according to the neighbor cell signal measurement result, and notifies the target cell of group configuration information through a core network.
The technical scheme of the invention is mainly applied to a broadband cluster system, and the terminal can be an interphone, a smart phone and other equipment supporting the group call service; in the application of the technical scheme of the invention, the terminal is equipment which enters the group calling service and is in an RRC idle state.
When a user uses a terminal, a group calling service can be initiated through the interphone, and other members in the group can be awakened; generally, a terminal initiating a group call is in an RRC CONNECTED state (RRC-CONNECTED), and other members in the group are in an RRC IDLE state (RRC _ IDLE); other members in the group may move between cells, and the continuity of the group call service needs to be ensured in the moving process. The technical scheme of the invention is a solution for mobility between cells of a terminal in an RRC idle state.
In practical application, the terminal can send the neighbor cell signal measurement result to the resident cell home base station in the following way; one way is that: the terminal sends an RRC signaling carrying a neighbor cell signal measurement result to a resident cell home base station; the other mode is as follows: and after receiving the query command sent by the resident cell home base station, the terminal sends a neighbor cell signal measurement result to the resident cell home base station.
And S102, the terminal receives a switching instruction which is sent by the resident cell home base station and carries a target cell identifier, and switches to the target cell according to the switching instruction.
S103, the terminal receives the cluster group calling signaling and the group calling wireless resource configuration signaling sent by the target cell home base station, and performs group calling service configuration according to the cluster group calling signaling and the group calling wireless resource configuration signaling.
It should be noted here that the terminal may obtain the cluster group call signaling and the group call radio resource configuration signaling sent by the target cell home base station from the handover instruction sent by the resident cell home base station; that is, the target cell home base station first sends the trunking group calling signaling and the group calling wireless resource configuration signaling to the resident cell home base station, and then the resident cell home base station forwards the trunking group calling signaling and the group calling wireless resource configuration signaling to the terminal. Of course, the terminal may also switch to the target cell first, and then receive the target cell home base station and directly send the cluster group call signaling and the group call radio resource configuration signaling to the terminal.
The invention has the technical scheme that a resident cell home base station of a terminal controls the terminal to complete cell switching, and the terminal executes the cell switching to continue entering the group calling service in a target cell; the method is completely different from the prior art that a terminal performs cell reselection, the cell reselection is an autonomous action of the terminal, the terminal disconnects a resident cell first and then resides in a target cell, then the target cell configures group information, and the terminal performs a group call service after the configuration is completed. The invention adopts the technical scheme that the resident cell home base station of the terminal informs the target cell of completing the configuration in advance, the preparation is made for the group calling service of the terminal after the switching in advance, and the terminal can directly enter the group calling service after the switching is completed according to the switching indication, thereby reducing the interruption delay.
Example 2
When there are many members in the group, a large amount of signaling overhead is easily generated in the process that a plurality of terminals in an RRC idle state simultaneously move to other cells, and in order to reduce the signaling overhead while reducing the interruption delay, the present invention also provides another technical solution, which is explained below.
Referring to fig. 2, a flowchart of embodiment 2 of the terminal-side movement control method of the present invention is shown, and the method may include:
s201, a terminal sends a neighbor cell signal measurement result to a resident cell home base station, so that the resident cell home base station selects a neighbor cell as a target cell according to the neighbor cell signal measurement result, and notifies the target cell and other cells in a tracking cell to which the target cell belongs to configure group information through a core network.
S202, the terminal receives a switching instruction which is sent by the resident cell home base station and carries a target cell identification, and switches to the target cell according to the switching instruction.
S203, the terminal receives the cluster group calling signaling and the group calling wireless resource configuration signaling sent by the target cell home base station, and performs group calling service configuration according to the cluster group calling signaling and the group calling wireless resource configuration signaling.
S204, other terminals belonging to the same group with the terminal receive the broadcast signaling sent by the resident cell home base station, judge whether the terminals accord with the condition of moving to the tracking area to which the target cell belongs, and if the terminals accord with the condition, carry out group call service configuration operation according to the cluster group call signaling and the group call wireless resource configuration signaling sent by one cell in the tracking area to which the target cell belongs; the broadcast signaling is used for broadcasting the configured group information of other cells in the tracking area to which the target cell belongs.
In the above technical solution, the camping cell home base station not only notifies the target cell of configuring the group information, but also notifies other cells of the tracking cell to which the target cell belongs of configuring the group information, so that all cells in the tracking cell to which the target cell belongs make good foundation for the movement of the group members in advance.
In practical application, the terminal may determine whether it meets the condition of moving to the tracking area to which the target cell belongs by using the following method, where the method specifically includes:
the terminal judges whether the RSRP (Reference Signal Received Power)/RSRQ (Reference Signal Received Quality) measurement value of the cell in the tracking area to which the target cell belongs is larger than the RSRP/RSRQ measurement value of the resident cell, if so, the terminal determines that the terminal accords with the condition of moving to the tracking area to which the target cell belongs.
The tracking area to which the target cell belongs is set up by the LTE system for location management of the user equipment, and the tracking area is a free mobile area in which the user equipment does not need to update services. When the user equipment is in an idle state, the core network can know the tracking area where the user equipment is located. The tracking area is configuration information at a cell level, the same tracking area can be configured for a plurality of cells, and only one tracking area can be configured for one cell, that is, only one tracking area can belong to one cell.
The above technical solution of the present invention is explained below with reference to specific examples.
Referring to fig. 3, the terminal a of the group call service initiator has terminals B, C, D, E, and F as members in the group; the group members are all in an RRC idle state, when a terminal B of the group members measures that a signal of a neighboring cell is better than that of a resident cell, an RRC connection request is sent to a base station 1 to which the resident cell belongs, the base station 1 establishes a context for the terminal B, so that the terminal and the base station can transmit and receive data mutually, the base station 1 selects a target cell for the terminal B according to a measuring result of the signal of the neighboring cell measured by the terminal B, if the terminal B measures that the signal of a neighboring cell 2 in the measuring results of the signal of the neighboring cells 1, 2, 3, 4 and 5 is the best, the base station 1 selects the neighboring cell 2 as the target cell, and all cells in a tracking cell to which the target cell belongs are informed of group configuration information through a core network. For example, there are neighboring cells 4 and 5 in the tracking area to which the neighboring cell 2 belongs, and when the neighboring cell 2 configures the group information, the neighboring cells 4 and 5 also perform the group information configuration. Thus, the terminal B is switched to the adjacent cell 2 according to the switching indication of the base station 1, meanwhile, the group member receives the broadcast signaling sent by the base station 1, the broadcast signaling is used for broadcasting that all cells in the tracking cell to which the adjacent cell 2 belongs complete the group information configuration, and when the group member terminals C, D, E and F meet the condition of moving to the tracking cell to which the adjacent cell 2 belongs, the group member terminals C, D, E and F can be directly switched to one cell of the tracking cell to which the adjacent cell 2 belongs, so that redundant signaling overhead can not be generated.
It should be noted that, in practical applications, the target cell described above may be another cell belonging to the same base station as the camped cell, and the target cell may also be a cell under a base station adjacent to the camped cell. Referring to fig. 3, the target cell neighboring cell 2 may be a cell belonging to the base station 1 or a cell belonging to another base station.
Example 3
Referring to fig. 4, a flowchart of embodiment 1 of the mobile control method at the base station side of the present invention is shown, and the method may include:
s401, a neighbor cell signal measurement result measured by the terminal is obtained.
In specific implementation, the base station may obtain the measurement result of the neighboring cell signal in the following two ways. The first mode is as follows: receiving an RRC signaling sent by a terminal, and extracting a neighbor cell signal measurement result from the RRC signaling; the second way is: and sending a query signaling to the terminal to obtain a neighbor cell signal measurement result reported by the terminal.
S402, selecting a neighboring cell as a target cell according to the signal measurement result of the neighboring cell, and notifying the target cell of group configuration information through a core network.
In practical application, the neighboring cell signal measurement result may be a neighboring cell RSRP/RSRQ measurement value, and then the base station may sequence the neighboring cell RSRP/RSRQ measurement values in descending order, and use the first ranked neighboring cell as a target cell. Of course, the base station may select the neighbor cell in other manners.
S403, sending a switching instruction carrying a target cell identifier to the terminal, so that the terminal switches to the target cell according to the switching instruction, and then performs group call service configuration according to a cluster group call signaling and a group call radio resource configuration signaling sent by a home base station of the target cell.
The technical scheme of the invention is that a base station controls a terminal to complete cell switching, the base station can send a switching instruction to the terminal after determining that a target cell completes configuration, and the terminal executes cell switching operation according to the switching instruction.
Example 4
When there are many members in the group, a large amount of signaling overhead is easily generated in the process that a plurality of terminals in an RRC idle state simultaneously move to other cells, and in order to reduce the signaling overhead while reducing the interruption delay, the present invention also provides another technical solution, which is explained below.
Referring to fig. 5, a flowchart of embodiment 2 of the mobile control method at the base station side of the present invention is shown, and the method may include:
s501, obtaining a neighbor cell signal measurement result measured by the terminal.
S502, selecting a neighboring cell as a target cell according to the signal measurement result of the neighboring cell, and notifying the target cell of group configuration information through a core network.
S503, sending a switching instruction carrying a target cell identifier to the terminal, so that the terminal switches to the target cell according to the switching instruction, and then performs group call service configuration according to a cluster group call signaling and a group call radio resource configuration signaling sent by a home base station of the target cell.
The base station may send a handover indication carrying a target cell identifier to the terminal after determining that the target cell completes configuring the group information.
S504, notifying other cells in the tracking area to which the target cell belongs to configure group information through a core network, and sending a broadcast signaling to the group with the terminal, wherein the broadcast signaling is used for broadcasting the configured group information of the other cells in the tracking area to which the target cell belongs, so that when the other terminals belonging to the same group with the terminal meet the condition of moving to the tracking area to which the target cell belongs, whether the other terminals accord with the condition of moving to the tracking area to which the target cell belongs is judged according to the broadcast signaling, and if the other terminals accord with the condition, group calling service configuration operation is carried out according to the group calling signaling and the group calling wireless resource configuration signaling sent by one cell in the tracking area to which the target cell belongs.
It should be noted that the steps S401 to S403 are the same as the steps S301 to S303, and are not described herein again. In addition, the steps S404, S402 and S403 do not have strict execution order requirements.
The technical scheme of the invention is that a base station controls a terminal to complete cell switching, the base station notifies a target cell to complete configuration after selecting the target cell, notifies other cells in a tracking cell to which the target cell belongs to complete configuration, and notifies the terminal that the target cell has completed configuration before switching, so that the interruption delay of a group call service in the terminal moving process can be reduced.
