Rapid or unit.
With specifically embodiment, technical scheme is described in detail below.These tools below
The embodiment of body can be combined with each other, may be in some embodiment for same or analogous concept or process
Repeat no more.
Fig. 1 is the schematic flow sheet of group data transmission method embodiment one of the present invention, as it is shown in figure 1,
The method of this enforcement is as follows:
S101:VPDCP entity receives and stores the group data that base band veneer sends, wherein, group
Group data comprise group information.
Specifically:
Group information is for uniquely identifying group, such as: group ID, group's name etc., to this present invention
It is not restricted, as long as can be identified for that group.
Virtual group convergence entity (Virtual Packet Data Convergence Protocol, letter
Claim: VPDCP) entity receives and states group data, and VPDCP entity uses PDCP
PDCP stack processes group data；And store the group data after described process.
S102:VPDCP entity obtains the community of base band veneer corresponding to group according to group information.
Specifically:
VPDCP entity according to the corresponding relation of group and the community of base band veneer and group information,
Obtain the community of base band veneer corresponding to group.Wherein, group is corresponding with the community of base band veneer closes
System is configured by high level.Further, this relation can be updated in real time according to the change of reality application.
It is corresponding that the descriptor memory symbol of storage group data is sent to group by S103:VPDCP entity
The rlc layer entity of the community of base band veneer, so that the community of base band veneer corresponding to group is according to interior
Deposit descriptor acquiring group data.
In the embodiment of the present invention, VPDCP entity is used to carry out grouped data remittance to group data is unified
Poly-entity (Packet Data Convergence Protocol, is called for short: PDCP) protocol stack processes,
It is managed collectively high-rise PDCP entity interface, reduces each community and manage the expense brought respectively, with
Time, unified by VPDCP entity handles to high-rise interface, also prevent that each community processes respectively can
The problem of the software mutual exclusion that can bring.
In the embodiment of the present invention, after group sets up, as long as there is user in group, group is corresponding
VPDCP entity exist the most all the time, after group cancels, then the VPDCP deleting correspondence is real
Body.When there being user because entering or exiting the Serving cell at base band veneer place, do not interfere with base band
Being normally carried out, because VPDCP has this group user at base band veneer of the business of these other communities single
Time exist all the time, other communities have only to after accessing receive from the data of VPDCP, and not
Needing to receive step by step from high level, the real-time for link establishment has greatly improved, and passes from data
Defeated angle, i.e. controls data surface packet loss.If not using VPDCP, add base band when there being user
During the Serving cell of veneer, group data duplication to be carried out from base band veneer so that the property of base band veneer
The loss of energy is serious, if using each community to act on behalf of the symbol transmission of this veneer group data descriptor memory respectively,
When Ze You exits group in community, the agency of group changes, and easily occurs that abnormal data abandons.
In the embodiment of the present invention, VPDCP does not carry out data content delivery, and only will store group
The descriptor memory symbol of data is sent to the wireless spread-spectrum technology of the community of base band veneer corresponding to group
(Radio Link Control, is called for short: RLC) layer entity, makes the little of base band veneer corresponding to group
District obtains group data according to descriptor memory symbol, it is achieved group data internal memory is shared.
Descriptor memory symbol, according to scheduling resource information, is sent to MAC layer by S104:RLC layer entity
Entity.
S105:MAC layer entity obtains group data according to descriptor memory symbol at VPDCP layer entity.
S106:MAC layer entity uses rlc protocol and MAC protocol encapsulation group data.
Owing to the group bag of rlc layer entity is relevant with scheduling, after scheduling completes, access control at media
(Medium Access Control is called for short: MAC) layer unification carries out RLC to group data system
Agreement and the encapsulation of MAC protocol, thus, it is ensured that do not have same data same by multiple tasks
Time use situation, thus, solve multiple cell mutual exclusion situation.
S107: eated dishes without rice or wine the group data after sending described encapsulation by physical layer group.
In the present embodiment, receive and store, by VPDCP entity, the group data that base band veneer sends,
Group data comprises group information；The described base band that described group is corresponding is obtained according to described group information
The community of veneer；It is corresponding that the descriptor memory symbol storing described group data is sent to described group by entity
The wireless spread-spectrum technology rlc layer entity of the community of described base band veneer, so that corresponding described of described group
The community of base band veneer obtains described group data according to described descriptor memory symbol.Thus realize all of little
The group data of storage in VPDCP is shared in district, reduces the consumption of datarams, at MAC layer entity root
Obtain group data according to descriptor memory symbol at VPDCP layer entity, use rlc protocol and MAC protocol
Encapsulation group data, decreases the number of times of data copy, and, solve multiple cell mutual exclusion impact, adopt
Realize with software, solve hardware and replicate hardware dependency difference high, portable and increase hardware cost
Etc. problem.
Fig. 2 is the schematic flow sheet of group data transmission method embodiment two of the present invention, as in figure 2 it is shown,
The method of the present embodiment is as follows:
S201: receive group data, comprise group information in group data.
Group information is for uniquely identifying group, such as: group ID, group's name etc., to this present invention
It is not restricted, as long as can be identified for that group.
S202: according to group information, group data is sent to the VPDCP of correspondence.
Specifically, also include:
Configuration group information and the corresponding relation of VPDCP.
Wherein, group is configured by high level with the corresponding relation of the community of base band veneer.Further, this relation
Can be updated in real time according to the change of reality application.
Fig. 3 is the schematic flow sheet of group data transmission method embodiment three of the present invention, as it is shown on figure 3,
The method of the present embodiment is as follows:
S301: receive group data, comprise group information in described group data.
S302: according to described group information, described group data is sent to the VPDCP of correspondence.
S303:VPDCP entity receives and stores the group data that base band veneer sends, described group
Data comprise group information.
S304:VPDCP entity obtains, according to described group information, the described base band that described group is corresponding
The community of veneer.
The descriptor memory symbol storing described group data is sent to described group by S305:VPDCP entity
The wireless spread-spectrum technology rlc layer entity of the community of the described base band veneer that group is corresponding, so that described group
The community of the described base band veneer that group is corresponding obtains described group data according to described descriptor memory symbol.
