With reference to Fig. 1, system 100 can comprise communication network 110, and communication network 110 can have the one or more network stations 112 that can communicate by letter with a plurality of mobile units 114 (such as, base station).At least three such mobile units 114 can form PTT group 116, and wherein at least one mobile unit 114 among the PTT group 116 serves as the unit 118 that starts.In a scheme, network 110 can be supported PTT communication, and in example more specifically, network 110 can be supported PoC communication.
As below explaining, the unit 118 that starts can produce to other mobile unit 114 participation in group call of PTT group 116 invitation.Then, based on the availability of other mobile units 114, network 110 can send session to the unit 118 that starts and begin message with the beginning groupcall.Although processing described above is undertaken by network, it will be apparent to one skilled in the art that and in no system, asynchronous communication environment, to realize this idea.
With reference to Fig. 2, show the example of the unit 118 that starts.Configuration described herein also can be applicable to other mobile units 114.The example of network station 112 also is illustrated among Fig. 2.In a scheme, the unit 118 that starts can comprise user interface 150, transceiver 152 and processor 154, processor 154 can be coupled to user interface 150 and transceiver 152 the two.As example, user interface 150 can comprise display, although other suitable components can be used as user interface 150.
In another program, network station 112 can comprise transceiver 160, memory 162 and processor 164, processor 164 can be coupled to transceiver 160 and memory 162 the two.In addition, memory 162 can be the part of processor 164, perhaps can be the independent unit under the control of processor 164.To provide description below to the operation of these parts.
With reference to Fig. 3, show the method 300 of groupcall.In order to describe this method 300, with reference to Fig. 1 and Fig. 2, although should be appreciated that, can in any other suitable system, use any other suitable components to come implementation method 300.In addition, the step of method 300 particular order that is not limited to provide in the accompanying drawings.In addition, method 300 can have than the step of the step greater number shown in the accompanying drawing or the step of smaller amounts.
In step 310, in the unit that starts, definable PTT group, wherein, PTT group has a plurality of members, and at least some members are essential members.In step 312, can produce the invitation message of the member's who comprises PTT group sign, and invitation message can be used for initiating groupcall.In step 314, invitation message can be transmitted into PTT group's member, and, in case launched invitation message, then can monitor at least some members' of PTT group usability status, shown in step 316.
After step 316, there are at least two options.For example, in step 318, when each of PTT group must the member can be used for carrying out groupcall, can receive session and begin message.As an alternative, shown in step 320, when at least one must the member be not useable for carrying out groupcall, can receive conversation failure message in the unit that starts.In addition, in step 322, can provide the indication of the member's who indicates PTT group availability by user interface in the unit that starts.
For example, see figures.1.and.2, in the unit 118 that starts, the user can be such as creating PTT group 116 by user interface 150.This PTT group 116 can comprise that the user wishes the contact person who gets in touch by the PTT groupcall.PTT group 116 can be the previous predefined group who produces of user, maybe can be the group that the user creates when the user wishes to initiate groupcall.At least some members of PTT group 116 can be essential members, and it is necessary that participation that must the member is proceeded groupcall for the user.The member of any suitable quantity can be essential member among whole members of PTT group 116, comprises PTT group 116 all members or a part of member.Which member the user of unit 118 of starting can specify is essential member, or can finish this point automatically based on predefined rule.
In case selected PTT group 116, the processor 154 of the unit 118 that then starts can produce invitation message, and this invitation message comprises PTT group 116 member's sign.This invitation message can be used to initiate the PTT groupcall.Then, the start transceiver 152 of unit 118 can be transmitted into this invitation message the transceiver 160 of network station 112.In case receive invitation message, the processor 164 of network station 112 can be determined PTT group 116 member's availability.
In a scheme, 112 the transceiver 160 of standing can be transmitted to invitation message PTT group 116 member's mobile unit 114.But participation in group call mobile unit 114 can make response to this invitation message, 112 the processor 164 of standing can monitor the response of reception, and their daily record is remained on such as in the memory 162.
As another example, one or more mobile units 114 can be relevant with network 110, so that mobile unit 114 can offer network 110 with available information before the unit 118 emission invitation message that start.Specifically, these mobile units 114 can send the information relevant with the availability of mobile unit according to predetermined scheduling, to receive transmission from network 110 or any other suitable source.Therefore, processor 164 may be stored in the availability of some mobile unit 114 in the memory 162, may not need to these mobile units 114 emission invitation message.In fact, can be before the user wish to set up groupcall, the availability of these mobile units 114 is sent to the unit 118 that starts.Like this, can send the invitation message of the sign that comprises these specific mobile units 114.
For purpose clear rather than restriction, the user that will provide the unit 118 that starts below wishes to begin with three contact persons the example of PTT groupcall.In these three members, two members in them can be essential member.Can suppose that also one in these mobile units 114 registers to network 110 in advance, this unit 114 can participate in the PTT groupcall, and is assigned as essential member.Like this, needn't send invitation message to this unit of registering in advance 114.
Yet network station 112 can be transmitted to invitation message the mobile unit 114 of not registered in advance.Continue this example, belonging to one of these unit 114 that residue must the member may currently can not participate in the PTT groupcall.For example, this must the member may carry out another calling or other transmission, may outside communication range his unit 114 be closed.PTT group's residue member's (only being nonessential member) mobile unit 114 can be made response to invitation message.
At this moment, stand 112 processor 164 can determine one must the member (that is, a member of registration) in advance and a nonessential member can participate in the PTT groupcall.Processor 164 can be stored in the usability status of these two unit 114 in the memory 162.As example, the state of two unit 114 can continue to be stored, up to the availability of having determined that at least all must the member.
Yet if the essential member's of residue mobile unit 114 is not made response, 112 the processor 164 of standing can produce conversation failure message, transceiver 160 with this conversation failure forwards to starting unit 118.Can be sent in the invitation message of specific quantity after the no response unit 114, or after measuring at the fixed time, produce this conversation failure message.In case receive conversation failure message, if necessary, the user of the unit 118 that then starts can attempt another groupcall after a while.
Begin message or conversation failure message no matter receive session, PTT group's member's the indication of availability all can be provided to the user of the unit 118 that starts in the unit 118 that starts.For example, if determine that PTT group's member is current available, then when showing the contact person on the display of unit 118, available particular color is played up (imbue) this contact person.This color can reflect contact person's availability.Similarly, can use another color to indicate that particular contact is current can not to participate in the PTT groupcall.If contact person's availability changes, then renewable contact person's color can participate in calling out so that this contact person to be shown now.Also can show special symbol, pattern or different colours, this user to the unit 118 that starts provides why disabled reason of special member, such as, member's mobile unit 114 outside coverage, be closed or currently carrying out another calling.
Although be described as in network 110, carrying out above method, it must be understood that, can in no system, asynchronous communication environment, carry out above method.Under this situation, a plurality of mobile phones can communicate with one another under the help that does not have network.In this example, the unit 118 that starts can be transmitted directly to invitation message PTT group's mobile unit 114, and can determine whether PTT group's member can be used for carrying out groupcall.
Although illustrated and described various embodiment, be noted that and so do not limit theme required for protection.Under the situation that does not break away from the spirit and scope of the present invention that are defined by the following claims, those skilled in the art will expect various modifications, change, variation, replace and be equal to.
