Description

The method and the device of a kind of POC service group member condition notice

Technical field

The present invention relates to the mobile communication technology field, relate in particular to the method and the device of a kind of POC service group member condition notice.

Background technology

The professional notion of POC (PTT over Cellular is based on the putting call through immediately after connection of cellular system) comes from intercom.The member of (Floor) of only obtaining the floor in the group could speak, and other members answer.The user need not dialing by preestablishing talk group during conversation, pin specific button, just can simultaneously speech be sent to other all members in the group, and button says that promptly calling and conversation connection procedure were finished in moment.The recipient need not any response and just can answer, and communication process adopts semiduplex mode, and a side is when speaking, and other members can only answer mute.

When the POC terminal use initiates the predefine group call, POC server will be according to member's tabulation of group, one by one the member in member's tabulation is invited to cluster conversation, these called members can select to answer POC invitation also can refuse POC invitation, and called member can call out maintenance or withdraw from session voluntarily simultaneously.Each group member all will write down corresponding state in POC server when doing these operations, for example, and connection status, not-connected status, calling hold mode, or the like.

If group member is all in advance at XDMS (XML Document Management Server, the XML document management server, be the server of data such as storage POC group information, individual contact list in the POC system) subscribed to the state of this group in the server, then when the POC calling terminal is initiated this group call, POC server will send the state that the group member state notification message is informed each member in the group to group member in calling procedure, at this moment, the member just can have at fingertips to each the member condition situation in the cluster conversation immediately in the group.

In the prior art, mainly be the notice that realizes the group member state by following technical scheme.

Suppose that POC terminal 1 creates a POC group in the XDMS server, for example, the ID of its group is: " POC Group "＜sip:POC-Group@networkA.net 〉, 3 POC users have been comprised in member's tabulation of this group: POC terminal 1, POC terminal 2, POC terminal 3, corresponding user ID is respectively: " POC UserA "＜sip:PoC-UserA@networkA.net 〉, " POC UserB "＜sip:POC-UserB@networkB.net 〉, " POC UserC "＜sip:PoC-UserC@networkC.net 〉).

The ID of group on being with in INVITE when POC terminal 1 makes a call, POC server is tabulated according to the ID of group will obtain this group from the XDMS server member, and makes a call one by one to each called member according to member's tabulation.

Fig. 1 is that POC terminal 1 is called out the part call flow diagram of POC group " POC Group ", prerequisite is POC terminal 1, POC terminal 2, POC terminal 3 have all been subscribed to this group in the XDMS server a state, when promptly this group and member condition thereof change in calling procedure, POC server will be notified and respectively subscribe to the terminal use.

As shown in Figure 1, corresponding processing procedure is as follows:

1 group of step 11:POC terminal use is the ID of group (" POC Group "＜sip:POC-Group@networkA.net 〉), POC terminal 1 will send INVITE (invitation) message to POC server by IMS (IP Multimedia System) network, in the message with the necessary information that goes up ID of group and calling.

Step 12:POC server is received the INVITE request that POC terminal 1 is sent, and will obtain member's tabulation from the XDMS server according to the ID of group, comprises POC terminal 1,2,3, and initiates to invite to each member except that caller according to member's tabulation.This moment, POC server was initiated the INVITE request to POC terminal 2.

Step 13:POC server is initiated the INVITE request to POC terminal 3.

Step 14:POC terminal 2 has been accepted group call invitation, and echoes and answer 200 OK message, the necessary medium interactive information of band in the message.

Step 15:POC server returns ACK (affirmation) message after receiving 200 OK message of POC terminal 2 immediately, and POC server is updated to connection status with the state of POC terminal 2 simultaneously.

Step 16:POC server has been received the successful respond that POC is called, and the expression session is set up, and will send at caller POC terminal 1 establishment 200 OK message and to POC terminal 1.

Step 17:POC terminal 1 is returned ACK message after receiving 200 OK immediately, after POC server is received the ACK message of POC terminal 1, the state of POC terminal 1 is updated to connection status.

Step 18:POC server detects that POC terminal 1 and POC terminal 2 have entered connection status in the group, is not in not-connected status but POC terminal 3 also enters session.POC server will send to POC terminal 1 with POC terminal 1, POC terminal 2, POC terminal 3 each member's state by NOTIFY (notice) message this moment.

After step 19:POC terminal 1 is received NOTIFY, each member's of group state is shown to the terminal use, POC terminal 1 is returned 200 OK to POC server immediately simultaneously.

Step 110: almost take place simultaneously with step 18, POC server sends to POC terminal 2 with each member's of group state by NOTIFY.

After step 111:POC terminal 2 is received NOTIFY, know the state of each member in the group, return 200 OK to POC server immediately.

Step 112: POC terminal 3 enters session than later for some reason, for example: POC terminal 3 enters session than 2 late 1-2 seconds of POC terminal, after POC terminal 3 is received the INVITE of step 13, return 200 OK message, the necessary medium interaction message of band in the message to POC server.

After step 113:POC server is received the success response of POC terminal 3, will give 3 times ACK of POC terminal immediately, the state with POC terminal 3 is updated to connection status simultaneously.

Step 114-115: because POC terminal 3 state variation, POC server is notified to POC terminal 1 with the state of POC terminal 3 by NOTIFY.

Step 116-117: because POC terminal 3 state variation, POC server is notified to POC terminal 2 with the state of POC terminal 3 by NOTIFY.

Step 118-119:POC server is told POC terminal 3 with the state of each member in the group by NOTIFY, and POC terminal 3 will be shown to the user, and the user of POC terminal 3 just knows at present for which member in the group, and each member's state how.

In the POC group calling, each group member can not all be in activated state in the connection status that PPP connects or PDP connects of packet domain, some POC terminal called is set to manual answering simultaneously needs the user to confirm, so each called member responds the time of POC server difference is arranged, for example, in wireless network, because the called data service of POC that has is in dormant state, after needing an activation, INVITE just can arrive terminal called, and the time that this moment, these users entered session will postpone longer.Change will notify group each member immediately if certain called member one enters session status.POC server will repeatedly notify group each member, and for example, the laggard called member who goes into session has 10, but these 10 members' the time span that enters session may be 2 seconds even longer, and the number of times of NOTIFY will be very many this moment.Be example with above-mentioned call establishment again, have 3 users in the group, POC server has just been sent out 5 times NOTIFY altogether.

Therefore, according to present scheme, as long as each User Status POC server that changes just is notified to each member of group at once in the group, at this moment, NOTIFY will become how much ranks increases, and the load of network and each POC terminal will greatly increase.

Summary of the invention

In view of above-mentioned existing in prior technology problem, the purpose of this invention is to provide the method and the device of a kind of POC service group member condition notice, reduce the scheme that NOTIFY sends frequency, reduce the live load of network and POC terminal.

The objective of the invention is to be achieved through the following technical solutions:

The invention provides the method for a kind of POC service group member condition notice, described method specifically comprises:

A, POC terminal are created POC service group in xml document management server XDMS, perhaps, after the POC terminal is created temporary group calling group, initiate to invite by POC server other POC terminals in POC service group or POC terminal establishment temporary group calling group;

B, POC server are initiating to invite to described other POC terminals, and after the predetermined delay time section of time-delay, state notifying POC service group or the POC terminal of each member in the group are created each member in the temporary group calling group.

Described steps A comprises:

A1, POC terminal have the ID of group in inviting INVITE when initiating to invite, perhaps, be with all called ID in INVITE;

A2, POC server are tabulated according to the member that the described ID of group obtains this group, and initiate to invite to other POC terminal according to member's tabulation of described group, perhaps, initiate invitation according to all the called ID in the message to corresponding POC terminal.

Described step B comprises:

Initiate notification timer when B1, POC server initiate to invite to other POC terminal;

B2, when the notice timer expiry, POC server detects each member's of group state, and each member of notice group.

Described method also comprises:

C, POC server pass through for the second time or time delays repeatedly again, reach behind each predetermined delay time each member in the state notifying group of each member in the group.

Described step C comprises:

C1, POC server be the initiate notification timer once more or repeatedly;

C2, when the notice timer expiry, POC server detects each member's of group state, the member condition information that collection status changes, and each member of notice group.

The second time among the described step C or repeatedly predetermined delay time are less than the predetermined delay time of last time.

Described step C also comprises:

When each member's of group state does not change, then needn't notify.

Described step C comprises:

Embodiment

Core of the present invention is at the very high situation of NOTIFY transmission frequency, the scheme that a kind of NOTIFY of minimizing sends frequency has been proposed, because each group member can not all be in activated state in the connection status of packet domain, some POC terminal called is set to manual answering simultaneously needs the user to confirm, so each called member responds the time of POC server difference is arranged, but each member's response time span not very big.Therefore, the present invention can increase a notice timer in POC server each cluster conversation, and this timer duration can be revised.POC server is at initiate notification timer when each called initiation is invited, and when the notice timer expiry, the state unification that POC server detects each member of group is notified to each group member.When becoming connection status, the called member condition that enters session at last notifies immediately.

Be described in detail below in conjunction with the specific implementation process of accompanying drawing, as shown in Figure 2, specifically comprise following processing procedure the method for the invention:

Step 21, a POC terminal have the ID of group in inviting INVITE when initiating to invite;

Step 22, POC server obtain member's tabulation of this group according to the described ID of group;

Step 23, POC server initiate to invite to other POC terminal according to member's tabulation of described group, and while execution in step 24 and step 28;

Step 24, the predetermined delay time initiate notification timer of basis;

Step 25, when the notice timer expiry, execution in step 26, otherwise continue to wait for;

Step 26, POC server are with each member of detected each member's of group state notifying group;

Step 27, judge whether to require time-delay again to wait for that execution in step 24 in this way, otherwise execution in step 210;

Step 28, judge whether all group members are connection status, and execution in step 29 in this way, otherwise, continue to wait for;

Step 29, immediately with all members of each member's of group state notifying group.

Step 210, this notification procedure that finishes.

The setting of predetermined delay time can change in the above-mentioned step 24, generally be the delay time of being scheduled to and the delay time of being scheduled to that reaches each time later on for the second time that in POC server, sets in advance first, also can configure for the second time and the delay time of being scheduled to of each time later on and the conversion relation of predetermined delay time first.For example, establish predetermined delay time first, from for the second time, delay time reduces gradually, and generally can adopt next time predetermined delay time is last half.Bide one's time when return the time-delay that to carry out again etc. from step 27, at first obtain predetermined delay time that this time-delay waits for and carry out this step 24 again.

Carry out POC server in the above-mentioned step 26 each member's of state notifying group of detected each member of group process is also comprised as shown in Figure 3 process, specific as follows:

Step 31, judge whether each member's of group state changes, in this way, execution in step 32, otherwise, execution in step 34;

Step 32, the state among each member of group the distinguished member that member and state do not change that changes;

Step 33, POC server are notified to the member who once notified with the member condition information that state changes, and simultaneously all member condition information are notified to the member who newly enters session.

Step 34, execution in step 27.

Carry out POC server in the above-mentioned step 29 immediately with all members' of each member's of group state notifying group process, because all group members are connection status, then showing necessarily has the state of group member that variation has taken place; Its concrete process is as follows as shown in Figure 4:

Step 41, the state among each member of group the distinguished member that member and state do not change that changes;

Step 42, POC server are notified to the member who once notified with the member condition information that state changes, and simultaneously all member condition information are notified to the member who newly enters session.

Step 43, execution in step 210.

What also have explanation here is, after the concluding time time-delay, changes if any the group member connection status, as enters session or connect when disconnecting, and notifies all group members immediately.

The present invention also provides the device of a kind of POC service group member condition notice, specifically as shown in Figure 5, comprising: notice timer and predetermined delay time are provided with module, wherein:

Notice timer: be used in POC server record invitation time when other POC terminal is initiated to invite; And after surpassing predetermined delay time, notify POC server;

Predetermined delay time is provided with module: the predetermined delay time that each time is set that is used to notify timer.

For ease of understanding the present invention, the invention will be further described for example below.

For example, POC terminal 1 has been created a POC group in the XDMS server, has comprised 6 POC users in member's tabulation of this group: POC terminal 1, POC terminal 2, POC terminal 3, POC terminal 4, POC terminal 5, POC terminal 6.The ID of group on being with in INVITE when POC terminal 1 makes a call, POC server is tabulated according to the ID of group will obtain this group from the XDMS server member, and makes a call one by one to each member according to member's tabulation.

The precondition here is that each member of group has subscribed to the state of this group.

Can dispose the NOTIFY timer duration in the POC server, NOTIFY_TIMER is 6 seconds such as configuration.

Figure 6 shows that the flow process of POC terminal 1 initiation group call, this flow process purpose is how to control the transmission frequency of NOTIFY in order to introduce POC server, so do not mark in the drawings for the ACK affairs of INVITE and 200 OK of NOTIFY.

As shown in Figure 6, the processing procedure of POC terminal 1 initiation group call specifically may further comprise the steps:

Step 61:POC terminal 1 is initiated to initiate group call according to the ID of group, will send INVITE to POC server by the IMS network, band ID of group and respective media attribute in the message.After POC server is received INVITE, judge this session and do not set up, will from the XDMS server, obtain member's tabulation of this group according to the ID of group.Initiate invitation to each called member before, it is the NOTIFY_TIMER timer that POC server starts duration, will check each member condition of group when overtime and send each group member state to the member who has connected.

Step 62～66:POC server is invited to each called initiation according to the group member tabulation.

Step 67,69,610:POC terminal 2,3,4 are in activated state because its packet domain connects, echoing to POC server soon should, after but POC server is received the response of these terminals, do not issue the group member state notifying to them immediately, must continue to wait for before the NOTIFY timer expiry, whether to also have other terminal to enter.

Step 68, POC server have been received the successful respond that POC is called, and the expression session is set up, and will send at caller POC terminal 1 establishment 200 OK message and to POC terminal 1.

Process is for example carried out here, when the NOTIFY of POC server timer expiry, detect that POC terminal 1,2,3,4 is in connection status in this group, but POC terminal 5,6 is in not-connected status.

At this moment, will carry out following process:

Step 611～614:POC server will be constructed NOTIFY, in the message all members' of group state is listed, issue the member who is in connection status then, and in the status attribute of POC terminal 1,2,3,4, indicate and issued NOTIFY, when issuing NOTIFY for POC terminal 1,2,3,4 next time only with the member condition of state variation in the group.Start the NOTIFY timer simultaneously, duration is NOTIFY_TIMER/2 second.Certainly follow-up timer duration can change according to certain rule to be set.

Step 615: because POC terminal 5 is before receiving INVITE invitation, possible its packet domain is connected to dormant state, need the packet domain connection status be activated by the network equipment, INVITE just can be dealt on the POC terminal 5 then, the time of answering so echo is slow a little, receive that again the successful respond of POC terminal 5 responds after POC server has sent a NOTIFY, POC server is updated to connection status with the state of POC terminal 5.But do not issue the state variation that NOTIFY informs each member POC terminal 5 immediately.Also do not issue NOTIFY to POC terminal 5 immediately and inform all group member state status.

Step 616:POC terminal 6 is similar with POC terminal 5, and POC server is updated to connection status with the state of POC terminal 6.But do not issue the state variation that NOTIFY informs each member POC terminal 6 immediately.Also do not issue NOTIFY to POC terminal 6 immediately and inform all group member state status.

When the NOTIFY of group timer expiry, POC server detects in each member's the state of group, and the state of POC terminal 5,6 becomes connection status by not connecting, and the state of POC terminal 1,2,3,4 still is in connection status and does not change.

Step 617～620:POC server will be constructed NOTIFY and be sent to the current state that POC terminal 1,2,3,4 is informed their POC terminal 5,6 respectively, because POC server has been informed all member conditions of POC terminal 1,2,3,4 by NOTIFY, the member condition that this moment, carrier state changed in NOTIFY is promptly only with the state of POC terminal 5,6.

Step 621～622: simultaneously, POC server will be constructed NOTIFY and be sent to the state that POC terminal 5,6 is informed all members in their group respectively, owing to be to send NOTIFY to POC terminal 5,6 for the first time, need with all member conditions in all message.

Among the present invention, in subsequent process, after each member condition changes, POC server will be notified by NOTIFY immediately.

The present invention can also be applicable to the situation of temporary group calling, in the POC terminal when POC server is initiated temporary group calling, in corresponding INVITE, increase all called id informations, POC server initiates to invite to corresponding POC terminal according to each the called id information in the message, follow-up processing procedure is with identical at the processing procedure of common POC group, so no longer describe in detail.

The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
