Embodiment
In order that the purpose of the application, technological means and advantage are more clearly understood, the application is done below in conjunction with accompanying drawing
It is further described.
Existing LTE broadband cluster systems can realize the data transfer from GW to eNBs by existing concentrated speech business,
IP multicasting technologys need not be used.Aspect of eating dishes without rice or wine utilizes clustered paging mechanism, supports the called direct by beep-page message of paging
Group's resource is obtained, can quickly monitor group service；By with group number come determine group paging indicate, paging occasion, seek
The paging mechanism of channel etc. is exhaled, supports terminal to receive the paging of multiple groups simultaneously；By the periodic ranging for having established group
Mechanism, support lags quickly monitors group service into access customer.Based on above-mentioned broadband cluster system, the cluster is utilized in the application
The group paging technology of system realizes LTE broadcasting service.Specifically, it is broadcast group to establish a group, utilizes group paging
The data of UE listening broadcast groups are notified, realize broadcasting service.
Fig. 1 is the particular flow sheet of broadcasting service implementation method in the application.As shown in figure 1, this method includes：
Step 101, core net node is to core network gateway（GW）Issue the broadcast group identification to be established, broadcast data and wide
The effective coverage broadcast.
The foundation of broadcast group is initiated by core net node, and issues broadcast data.Can be according to the foundation side of common group
Formula carries out the definition of broadcast group.Wherein, broadcast group is made a distinction by broadcast group identification.The broadcast group to be established can be complete
Net broadcast group or regional broadcast group, are defined by the effective coverage of broadcast.The effective coverage of broadcast can according to base station,
Tracking area and/or cell are that unit is divided, so as to realize that diversified effective coverage is set.It is of course also possible to will broadcast
The effective coverage of group is arranged to the whole network, i.e. broadcast group is the whole network broadcast group.
Step 102, the broadcast data of reception is copied to base station corresponding with the effective coverage broadcasted by GW, and notice base station is built
Found corresponding broadcast group.
After GW receives the effective coverage of broadcast, according to the mapping relations in the region and base station, it is determined that corresponding with the region
Each base station, the broadcast data of reception is copied to each base station determined, and notify base station to be established in respective regions extensively
Broadcast group.
Wherein, therefore, can because the effective coverage of broadcast is probably to be divided in units of base station, tracking area or cell
The a certain base station range inside points region of energy belongs to the effective coverage of broadcast, and subregion is not belonging to the effective coverage of broadcast,
Then GW needs to notify base station only to establish broadcast group in the coverage for belonging to broadcast effective coverage.
Step 103, UE of the base station into the effective coverage of broadcast sends group page message of eating dishes without rice or wine, according to GW notice
Broadcast group is established, and broadcast data transmission is carried out in the broadcast group of foundation.
Base station receives the broadcast data that GW is replicated, and the effective coverage notified according to GW, and the UE into the region sends empty
Mouthful group page message, and the group for indicating in the beep-page message to establish is broadcast group.The beep-page message can be PTT
Paging message, the parameter groupType in PTT Paging message is defined as enumerated value, including broadcast group and common group
Group：Enumerated {Broadcast, NormalGroup}.When needing to establish broadcast group, by PTT Paging message
GroupType values are arranged to broadcast group Broadcast.
In addition, further to identify the monitoring priority of the broadcast group, can be carried in group page message of eating dishes without rice or wine wide
The precedence information of group is broadcast, the information can be issued by core net node by GW.For example, in PTT Paging message
The middle precedence information that group is carried using Group Priority fields.
Step 104, the UE of group page message of eating dishes without rice or wine is received, after it is determined that the group of beep-page message is broadcast group, directly
Monitor the broadcast data of the broadcast group.
Wireless user terminal（UE）After receiving group page message of eating dishes without rice or wine, if the groupType of group is
Whether Broadcast, UE determine that the group is broadcast group, be not that signing group is limited by the group, such as, whether the group
In the signing group list of subset, UE can be monitored directly.If UE has been in the monitoring of other group service
State, UE can carry out principle judgement according to the priority of original group service and the priority of broadcast group, decide whether to supervise
Listen the broadcast group.
In addition, can further include group in group message of eating dishes without rice or wine adds indication field, it is used to indicate whether to need
Group's addition is carried out, so as to notify the broadcast group where this UE of core net by group's addition.For example, in PTT
Represent to need to carry out group's addition and do not need for True and False by Join indicator value in Paging message
Carry out group's addition.Instruction in PTT Paging is needed to carry out group's addition（Join indicator = True）Broadcast
Group, UE need to initiate explicit Group Join processes when monitoring the group；Group need not be carried out to instruction in PT TPaging
Group adds（Join indicator = False）Group, Group Join processes need not be initiated when UE monitors the group.
When group's addition indication field in group message of eating dishes without rice or wine to be arranged to that group's addition need not be carried out, can keep away
Exempt from super big broadcast group, numerous UE initiate group's adition process simultaneously, can cause signaling storm, influence systematic function.
In addition, during UE listening broadcast groups, UE can also be sent to the measurement report Measurement of core net
The Group ID notice network sides of broadcast group are carried in Report or TAU Request message.
Meanwhile when being roamed out the broadcast effective coverage of broadcast group when UE listening broadcast groups, UE prompting users remove broadcast
Region, the signal of broadcast group can not be received.
So far, the broadcasting service implementation method in the application terminates.From the specific implementation of above-mentioned the application, the application
In broadcasting service implementation method, its have line side processing it is similar with the processing of common group service, processing fast and flexible, simultaneously for
The change very little of idle message, user terminal processes principle are identical with common group service, it is only necessary to which it is special that broadcast type is done
Processing；In addition, also supporting to configure broadcast group, the whole network and zonal broadcast are supported, is realized compared to MBMS technologies
Broadcast is more flexible.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements done etc., should be included within the scope of protection of the invention with principle.
