Background technique
In the prior art, the data packet of LTE voice service is usually smaller and delay sensitive, can wave according to dynamic dispatching
Take a large amount of Physical Downlink Control Channel (PDCCH).For the expense for reducing Physical Downlink Control Channel, LTE introduces semi-static tune
Spend (Semi-Persistent Scheduling, abbreviation SPS) carry voice traffic.SPS distributes to drop using periodic resources
The expense of low PDCCH, SPS higher level parameters (resource allocation interval, SPS HARQ process number etc.) are allocated to UE by RRC, only exist
The physical layer resources (PRB, MCS etc.) that SPS is used are informed using PDCCH control channel when SPS activation or release.
The re-transmission of data is supported when downlink SPS carries point-to-point service, wherein head is passed on SPS, is retransmitted and is adjusted with dynamic
Degree, but when downlink SPS is carried in point-to-multipoint group service, due to confirmation character (ACK) no in LTE and negative acknowledge

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The term " includes " of description and claims of this specification and " having " and their any deformation, it is intended that
Be to cover it is non-exclusive include, for example, the device of the process or structure that contain series of steps is not necessarily limited to clearly arrange
Those of out structure or step but may include other steps being not clearly listed or intrinsic for these processes or device
Rapid or structure.
Referring to Fig. 1, Fig. 1 is a kind of flow chart for company-data transmission method that one embodiment of the invention provides.Such as Fig. 1 institute
Show, this method comprises the following steps:
Step 101, core network server receive the ability information that each member terminal reports in group, the ability information packet
Include the first SPS number of retransmissions that corresponding member terminal is supported.
The first SPS weight that member terminal is supported is included at least in the present embodiment, in the ability information that member terminal reports
Number is passed, can also include the coding mode that member terminal is supported, wherein different member terminals is corresponding in group optionally
The first SPS number of retransmissions and coded format may be different, the coding mode that member terminal is supported in the present embodiment can be narrow
With any one or more in voice coding (NVOC) format, adaptive multi-rate speech coding (AMR) format, but simultaneously not only
It is limited to NVOC format and AMR) format.
Optionally, the core network server ability information that each member terminal reports in receiving group in the present embodiment
Afterwards, the ability information that each member terminal reports also is sent to cluster server, cluster server is according to member each in the group
The coded format that terminal is supported, determines the coded format of the user face data of the group, wherein a group corresponds to user face number
According to coded format it is either one or more, when member terminals all in group support a kind of coded format,
Determine that the coded format is the coded format of the user face data of the group, when member terminals all in group support M kind coding
When format, it is determined that the M kind coded format is the coded format of the user face data of group, is issued in the M parallel and encodes lattice
The group user face data of formula.
Step 102, the core network server retransmit secondary according to the first SPS that member terminal each in the group is supported
Number, configures the SPS retransmission information of the group, and the SPS retransmission information includes the 2nd SPS number of retransmissions.
In the present embodiment, the 2nd SPS re-transmission time of group is included at least in the SPS retransmission information of core network server configuration
Number, can also include the corresponding SPS resource allocation interval of the group optionally.
Optionally, in the present embodiment, the minimum SPS that core network server can be supported according to member terminal in group is retransmitted
Number configures the SPS retransmission information of group, for example, the minimum SPS number of retransmissions supported in all member terminals can be matched
It is set to the corresponding SPS number of retransmissions of group (i.e. the 2nd SPS number of retransmissions), and is based on preset SPS number of retransmissions and SPS
Corresponding relationship between resource allocation interval, the corresponding SPS resource allocation interval of the 2nd SPS number of retransmissions of configuration, such as the SPS
Resource allocation interval can be 10 subframes or the subframe of other numbers.
The member that the SPS retransmission information of the group is sent to the group by step 103, the core network server is whole
End, so that the member terminal receives data according to the 2nd SPS number of retransmissions, or will according to the SPS number of retransmissions
Multiple VoPs are merged into a data packet and carry out repeating transmission.
It is exemplary, when the corresponding 2nd SPS number of retransmissions of group be N when, member terminal when receiving data, if first
The data packet decoding of SPS is correct, then ignores remaining N-1 SPS transmission, if the data packet decoding error of first SPS, receives
The data packet of two SPS is done mixed automatic retransfer (HARQ) and merges decoding by the data packet of second SPS；If correct, ignore residue
N-2 SPS transmission.And so on, if the data packet decoding error of preceding N-1 SPS, the data packet of n-th SPS is received, it will be N number of
The data packet of SPS is HARQ and merges decoding.If decoding is correct, high level is sent the data to.If mistake, this decoding data is abandoned.
When member terminal send data packet when, member terminal by the packet combining of predetermined number at a data packet, so
The data packet is carried out afterwards to repeat transmission on continuous N number of SPS.For example SPS resource allocation interval is 10ms, every 60ms is one
A re-transmission period.One data packet repeats to send on 6 SPS in same re-transmission period.
Certain above-mentioned example is merely illustrative to be illustrated rather than to unique restriction of the invention.
Optionally, when the member terminal application right of speech in group, the present embodiment as shown in Figure 2 can also include as follows
Step:
When step 201, the core network server receive the right to apply for words of the member terminal, by the right to apply for words
The coded format of middle carrying is sent to the cluster server.
Member terminal sends right of speech to core network server when to core network server application right of speech in the present embodiment
Apply, at least carries coded format in the right to apply for words, optionally, the above-mentioned 2nd SPS number of retransmissions can also be carried.
Step 202, when the cluster server authorizes the member terminal right of speech, the cluster server is returned
The coded format of the member terminal be sent to the member terminal.
The downlink for the group that the cluster server returns is established the coded format carried in signaling by step 203
It is sent to base station corresponding to the group.
