As shown in fig. 3, a method for dynamically managing an MBMS service area in a group communication system according to an embodiment of the present invention includes:
in step S101, the server receives location information reported by the UE in each cell of the first MBMS service area.
The server may be an MCPTT server, and the MCPTT group communication system configures a triggering condition for reporting the UE location information, where the triggering condition includes a condition for triggering the UE to report the location information, such as an MBMS bearer enabled cell change, an MBSFN (Multicast Broadcast Single frequency network) service area change, and an MBMS service area change. When the triggering condition for reporting the position information meets or receives the position information requested by the MCPTT server, the MCPTT client of the UE generates and sends the position information to the MCPTT server, and the position information reported by the UE comprises the cell information of the UE, the MBMS service area information and the like.
Next, in step S102, the server evaluates, according to the location information and a preset group cell list, to obtain MBMS bearer efficiency of each cell of the group in a second MBMS service area corresponding to the group.
The group cell list is a cell list of an MBMS service area corresponding to a group, and the cell list includes information of each cell in the MBMS service area. Specifically, the MCPTT server evaluates, according to the location information and a preset group cell list, the number of user equipments of each cell of the group in the second MBMS service area corresponding to the group, that is, the MBMS bearer efficiency of each cell of the group in the second MBMS service area corresponding to the group can be obtained.
Then, in step S103, the server identifies, according to the MBMS bearer efficiency, a cell in the second MBMS service area where the MBMS bearer efficiency is lower than a preset value as a dynamic adjustment candidate cell.
Finally, in step S104, when the server detects that the remaining available MBMS bearer resources in the cell of the second MBMS service area are lower than the preset MBMS bearer congestion threshold, the server determines that the MBMS bearer resources of the second MBMS service area are congested, and performs MBMS bearer disabling on the dynamically adjusted candidate cell in the second MBMS service area.
Specifically, prior to this step, the method further comprises: and the server updates the residual available MBMS bearing resources of each cell in the second MBMS service area.
In the embodiment, the server receives the position information reported by the UE in each cell of the first MBMS service area; evaluating and obtaining the MBMS bearing efficiency of each cell of the group in a second MBMS service area corresponding to the group according to the position information and a preset group cell list; identifying the cell with the MBMS bearing efficiency lower than a preset value in the second MBMS service area as a dynamic adjustment candidate cell according to the MBMS bearing efficiency; when the server detects that the residual available MBMS bearing resources of the cell in the second MBMS service area are lower than the preset MBMS bearing congestion threshold, the server determines that the MBMS bearing resources of the second MBMS service area are congested, and executes MBMS bearing de-enabling on the dynamic adjustment candidate cell in the second MBMS service area, and under the condition that the residual available MBMS bearing resources of the cell in the MBMS service area are insufficient, the dynamic management of the residual available MBMS bearing resources of the cell in the MBMS service area can be realized, so that the MBMS bearing resources of the group communication system are effectively utilized.
In a specific embodiment, the performing MBMS bearer de-enabling on the dynamically adjusted candidate cell in the second MBMS service area includes: the server de-enables the dynamically adjusted candidate cell from the group cell list for the group and switches the UEs of the group in the dynamically adjusted candidate cell from an MBMS multicast bearer to a unicast bearer.
Fig. 4 is a flowchart of an embodiment of dynamically adjusting MBMS bearer de-enablement for candidate cells. As shown in fig. 4, for the corresponding group to which the dynamic adjustment candidate cell in the MBMS service area relates, the dynamic adjustment candidate cell of the MBMS service area is disabled (disabled) from the cell list of the MBMS service area of the group in which it is located. The MCPTT server enables MBMS bearing of the MBMS service area to enable users under the cell to switch from MBMS multicast bearing to unicast bearing. The MCPTT server checks and updates the enabling state of the MBMS bearer disabling cell in the MBMS service cell list of the corresponding group. The MCPTT server checks and updates the MBMS bearing in the MBMS service cell list of the corresponding group to enable the MBMS bearing efficiency of the cell, and sets the MBMS bearing efficiency to be 0. The MCPTT server checks and updates the rest available MBMS bearing resources of each cell of the MBMS service area.
In another embodiment of the present invention, after performing MBMS bearer de-enabling on the dynamically adjusted candidate cell in the second MBMS service area, the method further includes: and the server updates the MBMS bearing efficiency of each cell in the second MBMS service area of the group and the residual available MBMS bearing resources of each cell in the second MBMS service area.
Further, the method further comprises: when the server detects that the remaining available MBMS bearing resources of each cell in the second MBMS service area are all higher than a preset MBMS bearing sufficient threshold, the server determines that the MBMS bearing resources of the second MBMS service area are sufficient, and enables the cell to execute MBMS bearing re-enabling on the MBMS bearing in the second MBMS service area.
Wherein the performing MBMS bearer re-enabling for the MBMS bearer de-enabling cell in the second MBMS service area comprises: the server checks the MBMS bearer efficiency of the group in the MBMS bearer de-enabling cell; the server judges whether the MBMS bearing efficiency reaches the preset value; if yes, the server judges whether the group has MBMS bearing multiplexing with other groups; if so, the server executes MBMS bearing re-enabling on the MBMS bearing de-enabling cell, and converts the UE of the group in the MBMS bearing de-enabling cell from unicast bearing to MBMS multicast bearing.
Fig. 5 is a flowchart of a procedure for re-enabling a cell by MBMS bearer according to an embodiment of the present invention. As shown in fig. 5, the MCPTT server checks the MBMS bearer of the MBMS service area corresponding to the group to enable the number of users of the present group under the cell, i.e., the expected MBMS bearer efficiency, if the MBMS bearer enables the MBMS bearer efficiency of the cell to be expected, and the cell is not an overlapping cell of MBMS bearer multiplexing, that is, there is MBMS bearing multiplexing between the group corresponding to the cell and other groups, the MCPTT server adjusts the MBMS service cell for the corresponding group, the MBMS bearing in the MBMS service cell of the group is disabled to enable the cell to carry out MBMS bearing Re-enabling (Re-enable), the MCPTT server switches the user equipment under the MBMS bearing Re-enabling cell in the MBMS service cell of the corresponding group from unicast bearing to MBMS multicast bearing, the MCPTT server checks and updates the enabling state of the MBMS bearing Re-enabling cell in the cell list of the MBMS service cell of the corresponding group, and the MCPTT server checks and updates the MBMS bearing efficiency of the MBMS bearing Re-enabling cell in the MBMS service cell list of the corresponding group. The MCPTT server checks and updates the MBMS bearing resources available for each cell of the MBMS service area.
In a specific embodiment, the MCPTT server analyzes and evaluates the MBMS bearer resources available to each cell in the MBMS service area, and evaluates the MBMS bearer efficiency of each cell of the MBMS service area corresponding to the group according to the location information reported by the UE. Based on the MBMS bearing efficiency, the MCPTT server dynamically manages the MBMS service area cell list corresponding to the group, and lists the cell with the MBMS bearing efficiency lower than the expected cell as an adjustment candidate cell of the MBMS service area. When the MBMS bearing resource of the cell of the MBMS service area is congested, the MCPTT server enables the adjustment candidate cell of the MBMS service area from the MBMS service area cell list of the corresponding group and converts the group user under the cell into unicast bearing. When the MBMS bearing resource of the cell of the MBMS service area is not congested, namely the MBMS bearing resource of the cell of the MBMS service area is sufficient, if the MBMS bearing efficiency of the group corresponding to the MBMS bearing disabling cell in the MBMS bearing disabling cell reaches the expectation and the MBMS bearing disabling cell is not an overlapped cell of MBMS bearing multiplexing, the MCPTT server enables the cell from the MBMS service area cell list of the corresponding group again, and converts the group user under the disabled cell to MBMS multicast bearing.
The embodiment dynamically adjusts the enabling and disabling states of the cells in the MBMS service areas corresponding to each group based on the position distribution of the UE and the MBMS bearing efficiency, thereby controlling the dynamic conversion of the downlink data transmission of the group communication service between the unicast bearing and the MBMS multicast bearing. Therefore, the distribution of the MBMS bearing resources among all the groups can be dynamically managed and optimized, thereby effectively utilizing the MBMS bearing resources and improving the performance of the group communication system.
Preferably, the method further comprises: the server analyzes and obtains a group meeting the MBMS load multiplexing condition according to a preset MBMS load multiplexing condition; and the server carries out MBMS bearing multiplexing on the group meeting the MBMS bearing multiplexing condition. Wherein the MBMS bearer multiplexing condition includes: the service Quality Class Identifiers (QCIs) of the groups are the same, and MBMS bearer enabling cells in MBMS service areas corresponding to the groups are not overlapped. Therefore, under the condition that the residual available MBMS bearing resources of the cell of the MBMS service area are insufficient, the dynamic management of the residual available MBMS bearing resources of the cell of the MBMS service area is realized, and the MBMS bearing resources of the group communication system can be further effectively utilized.
Fig. 6 is a flowchart illustrating a method for dynamically managing an MBMS service area in a group communication system according to another embodiment of the present invention. As shown in fig. 6, the group communication system configures a default cell list of the MBMS service area, sets the cell list of the MBMS service area of each group in the group communication system to a default value, and enables an MBMS bearer state of each cell in the MBMS service area. The group communication system configures the triggering conditions for reporting the position information by the UE, wherein the triggering conditions comprise conditions for triggering the UE to report the position information, such as enabling cell change, MBSFN service area change, MBMS service area change and the like. When the triggering condition for reporting the position information meets or receives the position information requested by the MCPTT server, the MCPTT client of the UE generates and sends the position information to the MCPTT server, and the position information reported by the UE comprises the cell information of the UE, the MBMS service area information and the like. And the MCPTT server evaluates the number of users of the group in each cell of the corresponding MBMS service area based on the position information reported by the UE, and obtains the MBMS bearing efficiency of the group in each cell of the corresponding MBMS service area. Based on the MBMS bearing efficiency of each cell of the group in the corresponding MBMS service area, the MCPTT server analyzes and identifies the cell with the bearing efficiency lower than the expected cell as the MBMS service area cell dynamic adjustment candidate cell. The group communication system configures MBMS load congestion threshold and MBMS load sufficiency threshold, and the MCPTT server checks and updates the rest available MBMS load resources of each cell of the MBMS service area. The measure of the MBMS bearer resource may be the number of MBMS bearers supported by the MBMS serving cell or the bandwidth of the MBMS bearer. When the rest available MBMS bearing resources of the cell of the MBMS service area are lower than the MBMS bearing congestion threshold, the MCPTT server determines that the MBMS bearing resources are congested, and executes the MBMS bearing disabling process of the MBMS service area to the dynamic adjustment candidate cell of the MBMS service area. The MCPTT server checks and analyzes the groups meeting the MBMS bearing multiplexing condition, analyzes the overlapping degree of MBMS bearing enabling cells of MBMS service areas among the groups for the groups with the same QCI, and identifies the groups with the same QCI and non-overlapping MBMS bearing enabling cells of the MBMS service areas as the groups meeting the MBMS bearing multiplexing condition. The MCPTT server carries out MBMS bearer multiplexing on the groups meeting the MBMS bearer multiplexing condition, and identifies the data streams of different groups by FlowID (stream ID). And the MCPTT server allocates proper MBMS bearing resources to the groups which do not meet the MBMS bearing multiplexing condition. For the affected group, the MCPTT server checks the MBMS bearer efficiency of each cell in the MBMS service area of the update related group. The MCPTT server checks for a remaining available MBMS bearer resource for each cell in the updated MBMS service area. When the MCPTT server detects that the remaining available MBMS bearer of the cell of the MBMS service area is higher than the MBMS bearer sufficiency threshold, the MCPTT server determines that the MBMS bearer resources are sufficient, and enables the cell to perform the MBMS bearer re-enabling process on the MBMS bearer of the MBMS service area corresponding to the group. The MCPTT server sends the list of the MBMS bearing enabling cells of the MBMS service areas corresponding to the group to the UE, and the UE monitors the information of the MBMS service area where the UE is located and receives downlink data.

Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
