Need to prove that it only is the module relevant with the embodiment of the invention that Fig. 1 a forms module with the PoC server shown in Fig. 1 b, and other existing module of PoC server is not shown in Fig. 1 a and Fig. 1 b.
Before the method for describing embodiment of the invention end PoC session, the process that PoC session is set up in simple description is as follows:
In order to set up PoC session, certain participant can send conversation request message to the PoC server as the session initiator, set up request (INVITE) such as session, the relevant information that comprises this participant in the INVITE request, invited other party information of this PoC session of adding etc., if the participant of being invited can normally add session, generally can send acknowledge message to the participant of initiating this PoC session, such as the 200OK response message by the PoC server.Each side's user profile that the PoC server will participate in PoC session is stored in this locality, and the PoC session of having set up is managed and controls.The specific implementation process of setting up PoC session can no longer repeat here referring to relevant PoC session related specifications.
It is emphasized that, participant carries the type identification of expression machine in conversation initialized protocol (SIP) message, the PoC server judges that according to the value of the type identification of this expression machine the participant of being invited is that machine also is non-machine, if the value of the type identification of expression machine is for really being TURE, promptly indicating the participant type is Machine Type, judges that then the participant of being invited is a machine; If the value of the type identification of expression machine is that vacation is FALSE, promptly indicating the participant type is non-Machine Type, judges that then the participant of being invited is non-machine.When the participant of being invited is machine, this machine is at sip message, be used to represent self to be the type identification of machine as carrying in the 200OK response message, the type sign can be stored in the existing Contact field of 200OK response message, such as automata field value is arranged in the Contact field is TRUE, and the sender who then represents this sip message is a machine.After the PoC server receives the 200OK response message, according to the value of the type identification of the expression machine that carries in this 200OK response message for true, be TRUE, judge that then the participant of being invited is a machine, and other user profile corresponding stored of the participant type of the participant that this quilt is invited and this machine is in the PoC server; When the session initiator is machine, be timed such as this machine and initiating the INVITE request to the PoC server sometime, at this moment, in the INVITE request, can carry to be used to represent self to be the type identification of machine, the type sign can be stored in the existing Contact field of INVITE request, after the PoC server receives the INVITE request, according to the value of the type identification of the expression machine that carries in this INVITE request for true, be TRUE, judge that then the session initiator is a machine, and with other user profile corresponding stored of this session initiator's participant type and this machine in the PoC server; When being non-machine as the session initiator or by the invitation participant, after the PoC server receives INVITE request or 200OK response message, be vacation according to the value of carrying the sign of expression participant type in this INVITE request or the 200OK response message, be false, judge the session initiator or be non-machine by inviting participant, and with other user profile corresponding stored of this session initiator or the participant type of being invited participant and this non-machine in the PoC server.
Initiate PoC session and invite certain machine to join in the session such as certain non-machine participant, implementation procedure comprises: this non-machine participant is initiated the INVITE request to the PoC server, because initiating the initiator of PoC session is non-machine, so the value of carry-on type identification is false in the INVITE request, represents that promptly this session participant is non-machine; After the PoC server of control session is received INVITE, the session initiator is carried out identity validation, simultaneously judge that according to the value of the type identification that carries in the INVITE request participant type of this participant is non-machine, and with this session initiator's participant type and this session initiator's relevant information corresponding record in the PoC server.PoC session according to PoC session related specifications regulation is set up process, and the INVITE request sends to by invited party by the PoC server that is used to control with managing conversation; As by the machine of invited party, after receiving the INVITE request message, in the Contact field of the 200OK response message that returns, carry the type identification that value is ture, after the PoC server receives the 200OK response message of this PoC device end, judge that according to the value of the type identification that carries in the 200OK response message participant type of this participant is a machine, and write down this accordingly by the participant type of invited party with this by the relevant information of invited party local.
So far, when setting up PoC session, the embodiment of the invention will participate in the participant class record of each participant of PoC session in the PoC server.
Need to prove, if the type identification that does not carry the expression machine in the message of POC session is set up in the participant request, POC server can judge that this participant is that machine also is non-machine according to the type of the participant of the strategy of operator or default value defined.
Participant type about above-mentioned judgement participant belongs to prior art, and specific implementation can be referring to related protocol.
Fig. 2 is the embodiment flow chart that the embodiment of the invention finishes PoC session, suppose that the PoC server determines whether finishing current sessions according to the number of session participant and the type of participant, and be provided with the participant type detection module of the participant type that is used to discern the PoC session participant in the PoC server, each participant of participation PoC session has been set up PoC session and has been in the PoC session, and the described end PoC session of the embodiment of the invention specifically may further comprise the steps:
Step 200～step 201: during current PoC session carried out, the PoC server judged whether to satisfy to trigger and finishes the PoC session treatment conditions, if do not satisfy, then returns step 200; Otherwise, enter step 202.
Trigger being provided with and being provided with in the PoC server by operator of PoC session treatment conditions, the participant that can be PoC session changes, change such as the type that has participant to withdraw from current PoC session or participant, such as switching to non-machine from machine or switching to machine etc. from non-machine; Also can be regularly to trigger PoC session handling process or the like.
Step 202:PoC server judges whether the participant number that is present in the current PoC session is less than or equal to one, if then enter step 204; Otherwise, enter step 203.
The PoC server has the PoC session processing capacity, therefore the group information that can form according to each participant of the participation PoC session that is stored in the PoC server of PoC server, judge whether the participant number that is present in the current PoC session is less than or equal to one, if do not have the user or have only a user in the group information, then the PoC server judges that the participant number in the current PoC session is less than or equal to one; If a more than user in the group information, then the PoC server judges that participant number in the current PoC session is greater than one.Specific implementation can no longer repeat here referring to the PoC session related specifications.
In this step, if the only surplus next bit of PoC session participant, no matter then this participant is non-machine, or machine; Perhaps do not have participant to exist, the PoC server all will enter step 204.If more than one of remaining PoC session participant, then the PoC server enters step 203 and does further judgement.
Step 203:PoC server judges whether the participant of PoC session is machine, if then enter step 204; Otherwise, return step 200.
Participant type detection module in the PoC server is judged the participant in the current PoC session according to being recorded in local information, if the participant type in the information of each participant shows that all participant is the type of machine, then the PoC server judges that the participant of PoC session this moment is machine; Otherwise, judge that the participant of PoC session this moment is not a machine entirely, continue this PoC session.
Here need to prove that the execution of step 202 and step 203 is order in no particular order.
Step 204:PoC server finishes current PoC session and discharges the Session Resources of each participant.
The PoC server sends end session message to each participant, such as BYE message, finishes current PoC session and discharges the Session Resources of each participant.
Need to prove, if in PoC session, certain non-machine participant switches to machine with self, or certain machine participant is switched to non-machine, the participant that switches to all can pass through type notification message with self participant type, as sip message, as INVITE, 200OK response message untill further notice PoC server, specific implementation can no longer repeat here referring to existing related specifications.
In addition, need to prove that if allowed before setting up PoC session, participant or PoC server administrators or operator dispose current PoC session at the PoC server and finish additional conditions, before each participant sent end session message, this method also comprised at the PoC server:
Step 2031:PoC server judges whether to have preset current PoC session and finishes additional conditions, if not default, then enters step 204; Otherwise, enter step 2032.
Step 2032:PoC server judges whether to satisfy and should finish additional conditions by default current PoC session, if do not satisfy, then returns step 200; If satisfy, then enter step 204.
Except before setting up PoC session, disposing current PoC session at the PoC server finishes outside the additional conditions, in current PoC session, participant can be used for sending to the PoC server to the message of PoC server transmission configuration information by current PoC session end additional conditions being carried at the existing subscriber.Here, the message that the user is used for to PoC server transmission configuration information can be sip message, such as: PUBLISH, or INVITE, or Re-INVITE message, or UPDATE message, or SUBSCRIBE message, or REGISTER message etc.
Default current PoC session finishes additional conditions in the PoC server has: participant add or return PoC session stand-by period length, timing finishes PoC session, certain participant withdraws from session and then finishes PoC session or the like.Such as: certain non-machine participant has been preset the stand-by period length that adds or return PoC session, promptly when the PoC server is judged the current PoC session of end, need the PoC server to wait for the time span of setting, if in set time span, this non-machine participant adds or has returned current PoC session, and then the PoC server is judged the satisfied default current PoC session termination condition that is somebody's turn to do; If in set time span, this non-machine participant does not add yet or returns current PoC session, and then the judgement of PoC server is satisfied and should be finished additional conditions by default current PoC session.In addition, regularly finish PoC session, certain participant and withdraw from session then to finish the realization and the said method of condition of PoC session similar, be not described in detail here.
Finish the method for PoC session finds out easily from the invention described above embodiment, embodiment of the invention method is by the type identification of the machine of participation PoC session, distinguish to participate in the machine of PoC session and the type of non-machine, and with the participant class record of participant in the PoC server.Under a plurality of participants are present in situation in the PoC session, when participant type detection module default in the PoC server according to the participant type detection of each participant that is recorded in the PoC server when participant is machine, the PoC server sends to each participant and finishes PoC session message, after finishing current PoC session and discharging the Session Resources of each participant.Irrational PoC session state that this method has avoided nobody to participate in reasonably finishes PoC session, has avoided the waste of the Session Resources of PoC system simultaneously effectively.
In the flow chart shown in Figure 2, the step 202 that enters in step 200～step 201 is changed into and enters step 203, can reach embodiment of the invention purpose equally like this, become the other method that the embodiment of the invention finishes PoC session.
Fig. 3 is another embodiment flow chart that the embodiment of the invention finishes PoC session, in PoC session, suppose that when the participant type of PoC server record PoC session participant noting the participant type simultaneously is the non-machine participant quantity of non-machine, and the default number that finishes.After the PoC server judged that satisfying triggering finishes the PoC session treatment conditions, this method comprised following two steps:
The quantity that step 300:PoC server is non-machine according to the described participant type of noting judges whether current non-machine participant quantity is less than or equal to the default number that finishes of PoC server, if then enter step 301; Otherwise, continue current PoC session and wait for that described triggering finishes to return step 300 after the PoC session treatment conditions satisfy;
Step 301:PoC server finishes current PoC session, and discharges the Session Resources of described participant
Described default end number can be preset as one such as this end number by the promoter of operator, PoC session, keeper or through the user who the authenticates decision that the keeper authorizes.
After above-mentioned PoC server judges that non-machine participant quantity is less than or equal to default end number in the current PoC session, enter before the step 301, this method can also comprise: the PoC server further judges whether the machine participant in the current PoC session has intelligence machine, as intelligent computer etc., if any, then return step 300, otherwise, step 301 entered.
Here intelligence machine is meant that this machine can carry out mutual machine with non-machine participant such as people, such as intelligent computer, content server etc.
The PoC server judges whether the machine participant in the current PoC session is intelligence machine, can judge by the function of the machine participant in the session.Can distinguish the machine participant according to the network address of machine participant such as the PoC server is intelligence machine, or non intelligent machine, such as, contain " computer " character in the network address of general intelligence computer, but not intelligence machine contains " recorder " character in the network address as recorder.Can also in PoC session, write down the Function Identification of the function that is used to represent the machine participant, can judge that the machine participant is an intelligence machine by the Function Identification of machine participant like this, or non intelligent machine, show that such as Function Identification pairing machine participant is an intelligence machine, then the PoC server judges that this machine participant is an intelligence machine; Function Identification shows that pairing machine participant is non intelligent machine, and then the PoC server judges that this machine participant is non intelligent machine.
At this moment, if allowed before setting up PoC session, participant or PoC server administrators or operator dispose current PoC session at the PoC server and finish additional conditions, at the PoC server before each participant sends end session message, the PoC server judges whether to have preset current PoC session and finishes additional conditions, if not default, then enter step 301; Otherwise the PoC server further judges whether to satisfy and should finish additional conditions by default current PoC session, if do not satisfy, then returns step 300; If satisfy, then enter step 301.
Be three kinds of specific embodiments that finish PoC session of the embodiment of the invention in the foregoing description, flow process enters step 204 or step 301 illustrates the current described PoC session termination condition that satisfies; Otherwise the current described PoC session termination condition that do not satisfy is described.
Need to prove, when only there is the machine participant in the embodiment of the invention in PoC session or the participant type be that the quantity of non-machine is less than or equal to when the PoC server is default to finish number, finish the method for PoC session, can distinguish separately as the condition that finishes PoC session, also can be jointly as the condition that finishes PoC session, can also be used in combination with the ending method of existing PoC session, common as the reason that finishes PoC session.The ending method of existing PoC session comprises: when the PoC keeper sends the method that finishes to finish when PoC session instructs PoC session, when last participant leaves in the PoC session, finish the method for PoC session, when leaving, the PoC session initiator finishes the method for PoC session, when leaving, finishes the PoC of appointment participant the method for PoC session, when being less than a certain numerical value, the quantity of participant finishes the method for PoC session, when leaving session, the promoter of session finishes the method for PoC session, when arriving, Preset Time finishes the method for PoC session or the method for end PoC session when in Preset Time, not having the participant speech.
The method that the PoC session ending method is used in combination can be for a PoC session is provided with a plurality of PoC session methods, as long as the reason that has a PoC session to finish satisfies, just finishes PoC session.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
