Fig. 2 is the flow chart of one embodiment of cluster communication method provided by the invention.Method provided in this embodiment can be with
Applied to dispatcher, ptt server etc..As shown in Fig. 2, the method for the present embodiment may include:
Step S201, request message is established according to group, sends group and establish notification message, group establishes notification message packet
The Temporary Mobile Group Identity TMGI, TMGI for including the group identification of group to be established and the multicast channel of group to be established are dispatcher
Distribution.
Multicast channel in the present embodiment is pre-established by dispatcher.Specifically, dispatcher can be according to algorithm every
Pre-establish a certain number of multicast channels under a service area (Service Area, referred to as: SA), be used for transmission group's voice and
Group's signaling allows group flexibly to bind the multicast channel under different SA when establishing.The present embodiment is for pre-establishing
Specific algorithm used by multicast channel with no restrictions, can pre-establish group using static, semi-static or dynamic mode
Broadcast channel.After multicast channel foundation, the letter for the MBMS multicast channel for needing that the current the whole network of all terminals is notified to pre-establish
Breath, for the TMGI information of signaling multicast channel, needs to be arranged the Internet protocol (Internet of the multicast channel
Protocol, referred to as: IP) address and port, group is monitored on signaling multicast channel so as to terminal establishes notification message.
Terminal in the present embodiment is session initiation protocol (Session Initiation Protocol, referred to as: SIP)
Pre-established terminal.In pre-established SIP session, terminal and dispatcher negotiation media information parameter, such as speech-encoded format,
User face IP address, port etc. are used for subsequent group speaker business and group's unicast service.Meanwhile dispatcher is after negotiation,
The carrying for triggering the QCI1 of Rx interface is established, and priority uses the signing priority of terminal user.
It should be noted that group, which establishes request message, can be the transmission of speaker's terminal, it is also possible to be given birth to by dispatcher
At.When meeting group's set up the condition, dispatcher sends group and establishes notification message, and it includes yet to be built that group, which establishes notification message,
The Temporary Mobile Group Identity TMGI, TMGI of the multicast channel of the group identification and group to be established of vertical group are dispatcher distribution
's.Specifically, dispatcher when group establishes, issues the Map Group To Bearer of TBCP on signaling multicast channel
Message is broadcasted, and notice multicast group is established, so that monitor terminal is according to the information carried in message in corresponding TMGI
Upper monitoring multicast group data.
Step S202, on the corresponding multicast channel of TMGI, multicast sends group data.
On the multicast channel for the group allocation, multicast sends the group data of the group, so as to monitor multicast letter
The terminal in road can obtain group data.The multicast channel can be MBMS multicast channel.
It needs to be emphasized that according to the regulation of 3GPP agreement 24380, even if group data is believed by MBMS multicast
Road issues, and terminal also supports multicast reception, the terminal pre-established for SIP, it is still desirable to issue TBCP Connect message
Go the group and pre-establish SIP session subscriber face binding, for carry it is subsequent rob power message transmitting and receiving and
Carry group's unicast voice data after subsequent multicast singulation is broadcast.I.e. by the regulation of 3GPP agreement 24380, in the step of the present embodiment
After rapid S201, before step S202, dispatcher needs all group user unicasts to the group to send TBCP Connect
Message.
The number of users of multicast group is theoretically infinity, the capacity of eating dishes without rice or wine of cell is not only restricted to, for professional cluster
User, such as public safety part, the number of users of group may reach thousands of.When establishing group, dispatcher is to thousands of
A user unicast simultaneously sends TBCP Connect message, and receives the response message of thousands of user, can not only make to eating dishes without rice or wine
Storm is accessed at signaling storm, including paging storm and space interface signaling, influences the business of other users, but also dispatcher can be given
It brings biggish signaling to send load, wastes schedules system resources, it is possible to influence the operation of other modules of system.Even more serious
It is to send a large amount of TBCP Connect message, will lead to the increase of group's setup delay, it is possible to cause information to lose problem, lead
It causes communication reliability to reduce, is unable to satisfy user demand.
TBCP Connect message is used to indicate terminal and binds the group and the SIP session subscriber face pre-established, with
It is easily carried the subsequent transmitting and receiving for robbing power message and/or carries group's unicast voice data after subsequent multicast singulation is broadcast.
However the foundation of group and release are very frequently, general activationary time was at about 20-30 seconds or so.Group it is lasting when
In, it is most likely that do not rob the switching of power or multicast to unicast.Therefore, it when group establishes, can not send
TBCP Connect message.
Cluster communication method provided in this embodiment, dispatcher establish request message according to group, send group and establish and lead to
Know message, group establishes the interim shifting of the multicast channel of the group identification that notification message includes group to be established and group to be established
Dynamic group mark TMGI, so that group user monitors group data on the multicast channel of the group, then at corresponding group of TMGI
It broadcasts on channel, multicast sends group data, reduces the time delay of group's foundation, realizes the quick foundation of multicast group.It is building
When vertical group, TBCP connection message is not sent to group user unicast, avoid the generation of signaling storm, save scheduling system
Resource improves the reliability of cluster communication.
On the basis of a upper embodiment, several specific embodiments are used separately below, robbing after establishing for group
Power process and multicast unicast handover process are described in detail.
Fig. 3 is the flow chart of the another embodiment of cluster communication method provided by the invention.As shown in figure 3, side shown in Fig. 2
On the basis of method embodiment, the method for the present embodiment can also include:
Step S301, the right of speech solicitation message that terminal is sent is received.
After group establishes, the monitor terminal in group monitors group data on the multicast channel of the group.Work as group
In monitor terminal want speech when, need to apply to become speaker's terminal to dispatcher application sending the right words message.Specifically,
Terminal can carry out the right to apply for words by the SIP REFER message indicated with the right to apply for words.
Dispatcher receives the right of speech solicitation message that terminal is sent, which can be any monitor terminal in group, adjusts
Degree machine may also receive the right of speech solicitation message that multiple terminals are sent simultaneously.
Step S302, the first response message is sent to terminal, the first response message carries right of speech and authorizes instruction information.
Dispatcher, to condition is met, can obtain the terminal of right of speech after the right of speech solicitation message for receiving terminal transmission
It sends and carries the first response message that right of speech authorizes instruction information.Finger is authorized specifically, can send to the terminal and carry right of speech
Show the 200OK message of information.
When there is multiple terminals application sending the right words message simultaneously, only one terminal can obtain right of speech, such as can be with
It is determined according to the priority of terminal.For the terminal of the right to apply for words failure, dispatcher sends to the terminal and awards without right of speech
Then the 200OK message given sends Floor Deny message and refuses the right to apply for words, terminate the terminal robs power process.Right of speech Shen
The reason of please failing, has in very much, does not repeat one by one herein.
Step S303, Talk Burst Control Protocol TBCP connection message is sent to terminal, TBCP connection message is used to indicate
Terminal binds pre-established session and group.
Due to not binding pre-established session and group when group establishes, dispatcher is determining that right of speech authorizes
Afterwards, it needs to send Talk Burst Control Protocol TBCP connection message to the terminal that will obtain right of speech, TBCP connection message is used for
Instruction terminal binds pre-established session and group.
Step S304, the second response message that terminal is sent is received, the second response message is the sound to TBCP connection message
It answers.
The second response message that terminal is sent is received, the second response message is the response to TBCP connection message.Specifically,
Second response message is terminal in the TBCP connection message for receiving dispatcher transmission, according to the TBCP connection message, by built in advance
After vertical session and the group is bound, sent to dispatcher.
Step S305, right of speech grant message is sent to terminal, right of speech grant message is used to indicate terminal and successfully obtains group
Right of speech.
Dispatcher sends right of speech grant message after receiving the second response message, to terminal, and right of speech grant message is used
The right of speech of group is successfully obtained in instruction terminal, becomes speaker's terminal, can be talked.Specifically, TBCP can be passed through
Floor Granted message instruction terminal.At the same time, other terminals of dispatcher into the group send right of speech and occupy instruction
Information, specifically, can be indicated by TBCP Floor Taken message.
Step S306, the group data that terminal unicast is sent is received.
Once the right to apply for words success, which becomes speaker's terminal, and uplink unicast sends group data, no longer reception group
Downlink unicast or multicast channel.Dispatcher receives the group data of terminal unicast transmission, and group data is believed in multicast
Multicast is sent to group user on road.
For example, for a group with 1000 group users, if during the group continues only
The primary power of robbing only has occurred, dispatcher meeting unicast when group establishes sends 1000 TBCP Connect and disappears in the prior art
Breath, and method provided in this embodiment only needs unicast to send 1 TBCP Connect message, avoids signaling storm, saves
Resource has been truly realized on-demand transmission.
Cluster communication method provided in this embodiment, dispatcher are not sent when establishing group to group user unicast
TBCP connection message only sends TBCP connection message to the terminal that will obtain right of speech, is used to indicate terminal in robbing power process
Pre-established session and group are bound, the group data that terminal unicast is sent is received in the carrying of session, is realized
The right to apply for words avoids signaling storm, saves resource, has been truly realized on-demand transmission.

On the basis of method embodiment, the method for the present embodiment can also include:
Step S401, the state report information that terminal is sent is received, state report information is used to indicate terminal can not be in group
It broadcasts and is properly received group data on channel.
Terminal monitors group data on multicast channel, when terminal can not be properly received group data on multicast channel
When, it can be to dispatcher status report information.For example, when terminal passes through real-time transport protocol (Real-time Transport
Protocol, abbreviation RTP) voice quality detection algorithm judges that multicast channel quality is deteriorated or can not receive group data
When, MBMS listening status report message is reported, indicates that current group's voice TMGI can not be received.
Step S402, Talk Burst Control Protocol TBCP connection message is sent to terminal, TBCP connection message is used to indicate
Terminal binds pre-established session and group.
Dispatcher receive terminal send state report information after, need by the communication between the terminal and dispatcher by
Multicast is switched to unicast, to ensure that terminal can be properly received group data.Due to when group establishes, not by pre-established meeting
Words and group are bound, and therefore, it is necessary to send Talk Burst Control Protocol TBCP connection message, TBCP connection message to terminal
Terminal is used to indicate to bind pre-established session and group.
Step S403, the third response message that terminal is sent is received, third response message is the sound to TBCP connection message
It answers.
The third response message that terminal is sent is received, third response message is the response to TBCP connection message.Specifically,
Third response message is terminal in the TBCP connection message for receiving dispatcher transmission, according to the TBCP connection message, by built in advance
After vertical session and the group is bound, sent to dispatcher.
Step S404, group data is sent to terminal unicast in the carrying of session.
After receiving third response message, dispatcher can send group number to terminal unicast in the carrying of session
According to.
For example, for a group with 1000 group users, if during the group continues, only
Only 5 terminals need to be switched to unicast by multicast, and dispatcher can unicast transmission 1000 when group establishes in the prior art
TBCP Connect message, and method provided in this embodiment only needs unicast to send 5 TBCP Connect message, avoids letter
Storm is enabled, resource is saved, has been truly realized on-demand transmission.
Cluster communication method provided in this embodiment, dispatcher are not sent when establishing group to group user unicast
TBCP connection message only sends TBCP connection message to the terminal needed from multicast to unicast handover, and being used to indicate terminal will be pre-
The session of foundation and group are bound, and are sent group data to terminal unicast in the carrying of session, are realized multicast to list
The switching broadcast, avoids signaling storm, saves resource, has been truly realized on-demand transmission.
