Difference can not be supported well to solve the secondary link buffer state report generated in conventional art mentioned above
The priority of target group communication, base station is asked in the relatively low technology of the resource utilization of the Radio Resource of distribution caused by
Topic, in one embodiment, spy propose a kind of generation method of secondary link buffer state report, and this method, which can be dependent on, to prop up
The user equipment (UE) of D2D business is held, for example, support the smart mobile phone of D2D business etc..
Specifically, as shown in figure 3, this method includes：
Step S102：Terminal iidentification and/or target group mark are uploaded to base station, it is excellent to receive the business that the base station is sent
The mapping table of first level and logic channel group mark, the mapping table and the terminal iidentification and/or the target group mark
Know, cell ID is corresponding corresponding to the terminal iidentification.
In the lte networks, base station generally includes one or more cell, and each cell corresponds to different wireless frequencies
Duan Ziyuan.When user equipment (UE) adds LTE network, it is necessary to base station eNB (base station equipment in LTE network), it is necessary to base
Stand and send the terminal iidentification of the user equipment (UE), be identified for all UE equipment that base station is administered to it.UE is on base station
It is assigned under some cell and is administered after registration, so as to facilitates the multiplexing of radio band resource.It is each under base station
Cell is respectively provided with identification code, and the identification code is cell ID.That is, user equipment (UE) is after LTE network is added, base
Stand and store terminal iidentification and cell ID corresponding to the user equipment (UE).
And for having carried out user equipment (UE) and the base station of D2D business, user equipment (UE) meets the mesh of D2D business creating
, it is necessary to report the target group of the target group of establishment to identify (or being allocated by base station) to base station when marking group.Namely
Say, user equipment (UE) and base station for having carried out D2D business, the terminal iidentification of the user equipment (UE) and small is stored with base station
The establishment that area identifies and the user equipment (UE) creates meets the target group mark of the target group of D2D business.
In the present embodiment, base station is assigned accordingly for user equipment (UE) that is registered and having carried out D2D business in advance
Service priority and the mapping table of logic channel group mark.Service priority is that application layer defines previously according to type of service
Priority tag corresponding with type of service.In the present embodiment, the PPP that 3GPP Rel-13 are defined can be used in service priority
(Per-Packet Priority) priority.In 3GPP Rel-13 standards, service priority PPP is defined as 8 levels,
By PPP1 to PPP8, its priority is set from high to low.That is, service priority is defined as PPP1 type of service
Highest priority, the priority that service priority is defined as PPP8 type of service are minimum.Need in distributing radio resource,
It is defined as the PPP1 preferential distributing radio resource of type of service for priority, is finally defined as PPP8 business for priority
Type priority distributing radio resource.
Preferably, corresponded in mapping table high priority logic channel group mark service priority priority be higher than or
Equal to the service priority of the logic channel group mark of corresponding low priority.That is, in the mapping table, corresponding to PPPn
The priority that the priority of LCG marks is always above or identified equal to LCG corresponding to PPPn+1.If for example, PPP3 mapping LCG marks
Know 01, then PPP4 can only map LCG marks 01,10 or 11, but can not map LCG marks 00.
In the present embodiment, for the user equipment (UE) of execution this method, base station can be according to the cell of the user equipment (UE)
Mark, terminal iidentification or the corresponding mapping table set in advance of target group mark selection are sent to the user equipment (UE), the use
The corresponding mapping table that family equipment UE can issue according to base station generates secondary link buffer state report Sidelink BSR, the life
Into Sidelink BSR can reasonably using service priority to base station requests Radio Resource carry out D2D business data pass
Defeated business.
Step S104：Target group mark is obtained, obtains the size for the buffered data packet for issuing the target group mark
With the service priority of type of service and each type of service.
Step S106：The business of the buffered data packet identified according to the mapping table search with issuing the target group is excellent
Logic channel group corresponding to first level identifies.
Step S108：According to the logic channel issued the buffered data packet size of the target group mark and found
Group mark generates secondary link buffer state report.
For example, as shown in figure 1, if target group corresponding to user equipment (UE) has two, and corresponding target group mark
2 are identified for target group mark 1 and target group, if priority of the type of service of target group mark 1 in communication service
It is higher, it is PPP1, the priority of the type of service of target group mark 2 in communication service is relatively low, is PPP6, then can be in business
Priority LCG marks corresponding with searching PPP1 and PPP6 in logic channel group identity map table respectively.If in the mapping table
LCG corresponding to PPP1 is identified as LCG corresponding to 00, PPP6 and is identified as 10, then user equipment (UE) when generating Sidelink BSR,
It can first define a target group according to BSR as shown in Figure 2 form and identify 1 buffer status BS and corresponding buffering
Data package size and LCG marks 00, re-define a target group and identify 1 buffer status BS and corresponding buffered data packet
Size and LCG marks 10.That is, user equipment (UE) LCG can identify according to corresponding to the type of service of target group mark
Priority orders define successively each target group mark type of service buffer status BS, so as to generate Sidelink
BSR。
It should be noted that a target group may have multiple types of service, each type of service tool in application layer
There are corresponding service priority PPP values, now user equipment (UE), then can be according to different business when generating Sidelink BSR
The different buffer status BS of type definition and corresponding buffered data packet size and LCG marks.
As above in example, if service priority of the type of service A of target group mark 1 in communication service is PPP1, mesh
It is PPP5, the type of service C of target group mark 2 to mark service priority of the type of service B of group identification 1 in communication service
Service priority in communication service is PPP3, and the business of the type of service D of target group mark 2 in communication service is preferential
Level is PPP8.And LCG corresponding to PPP1 is identified as LCG corresponding to 00, PPP3 and is identified as corresponding to 01, PPP5 in the mapping table
LCG is identified as LCG corresponding to 10, PPP8 and is identified as 11, then user equipment (UE), can be according to such as figure when generating Sidelink BSR
The form of BSR shown in 2, first define a target group and identify 1 buffer status BS and corresponding buffered data packet size
With LCG marks 00, buffer status BS and corresponding buffered data packet size and LCG that a target group identifies 2 are re-defined
Mark 01, re-define the buffer status BS and corresponding buffered data packet size and LCG marks of a target group mark 1
10, re-define the buffer status BS and corresponding buffered data packet size and LCG marks 11 of a target group mark 2.
Base station then can be followed successively by target after the Sidelink BSR are received according to the LCG priority orders identified
Group identification 1 and target group identify 2 distributing radio resources.As above in example, if being preferably the wireless money of the distribution of target group mark 1
Source, then 2 distributing radio resources are identified for target group, it is again then the extra Radio Resource of the distribution of target group mark 1, then
The Radio Resource for distribution extra obtain of target group mark 2 again.It is so as to the height according to service priority, Radio Resource is reasonable
The business in the higher target group of service priority is distributed on ground, improves resource utilization.
In the present embodiment, specifically, base station is according to the cell ID of user equipment (UE), terminal iidentification or target group mark
