In other words, according to the application of a user (for example A), this user is registered in the home address registering section (HLR).The user of this registration is requested to be registered in visitor's address registration part (not shown) in advance.And carry out the voice mixing among the CMXU in being included in the ASS-S of MSC, so that MS is the calling party, so that between two parts or many parts, call out.Therefore when participating in a conference communication, the user of conference participation can hear themselves sound.
Fig. 3 be expression according to a flow chart of conference service method of the present invention, the algorithm that wherein is used for conference service is to carry out in the mobile multiplexer (MUX (MMUL) of the ASP in being contained in the ASS-M of MSC.
Conference service method according to the present invention is carried out by the following step: carry out basic communication (step S1) by conference communication between the user or universal telephone communication, pass through during basic communication to select conferencing function to carry out meeting (step S2) with the meeting function user, if during conference communication, had from another user's call request would make existing conference users wait for and with another telex network (step S3), during conference communication, add another user and allow conference communication to proceed (step S4); Behind step S3 and S4, carry out meeting (step S5) once more, check whether the conferencing function user has produced the user is deleted ID, and not the time meeting procedure (step S6) of execution in step S2, delete ID if produced the user at step S6, select to carry out user's delete program and return meeting step S2 (step S7) then, and delete/add access customer (step S8).
During conference communication according to the present invention, on Call Waiting step S3, as shown in Figure 4, when conference communication is undertaken by phone, if receive new user (as the user D) request for conference that the line is busy (step S3-1) of seeking a meeting function user (for example mobile radio station shown in Fig. 1 (MS) A) from one in MMUL, MMUL just determines whether to provide call waiting function (step S3-2) to the new user of the request for conference that proposes that the line is busy.The call waiting function of supposing this user is registered in by visitor's address registration that ASP the controlled part (VLR) that is loaded on the ASS-M among the MSC.
If new user assembled call waiting function, MMUL exports to call waiting signal the user of the request for conference check that is subjected to that the line is busy, for example, conferencing function user (supposing that call waiting function is registered here) is with the notice request for conference (step S3-3) that has that the line is busy.
Therefore, if the user (for example conferencing function user) of the meeting that is requested that the line is busy (has for example pressed the transmission key, " SEND " key) (step S3-4), MMUL (below, broadly be called switching system) call waiting signal is exported to all users of the communication that participates in a conference to keep communication (step S3-5).Then, the user (for example conferencing function user A) of a new user (for example user D) and the meeting that is requested that the line is busy is connected to carry out bipartite telephone communication (step S3-6).If again by sending key, switching system will determine to send the MMUL whether signal is input to ASP to the user of the meeting that is requested that the line is busy after finishing communication.
In the case, if sending key is transfused to once more, the switching system cancellation is for all users' the call waiting signal that it is waited in the conference communication process, and call waiting signal exported to a new user (step S3-8), so that be transformed into conference communication, with the existing user's that recovers to communicate by letter conference communication (step S5) with conference participation.By such operation, when input sends key, during conference communication, can repeatedly carry out the Call Waiting service.
Therefore, according to the present invention, if when the calling of a new reception is arranged in the conference communication process by phone, the user (conferencing function user) that call waiting function is housed selects to carry out the user of conference communication and the calling party of new calling by his/her key operation, so that carry out telephone communication and conference communication.So, even during the conferencing function user participated in a conference, he also can notified urgent contact.
As shown in Figure 5, during conference communication, add in the step (step S4) of access customer, if have one by the call request (step S4-1) of another user to switching system when carrying out telephone communication (step S2), then whether switching system check conferencing function user has registered the user who is used to be provided with another user and has added function (step S4-2).
At this moment, if the user that the conferencing function user does not have registration to be used to be provided with another user adds function, switching system will be ignored the calling input of setting up into another user, so that make conference communication can proceed (step S4-2).On the other hand, if having registered the user who is used to be provided with another user, the conferencing function user adds function, just switching system sends to a call waiting signal the existing user (step S4-31) who carries out telephone communication.Then, another user be provided with the user that the user adds function, promptly the conferencing function user interconnects (step S4-32), so that this two side carries out telephone communication (step S4-33).
In this case, " SEND " key that switching system determines whether to be located on conferencing function user's the phone is transfused to, if this transmission key is not transfused to (step S4-34), and execution in step S4-33 then.If this transmission key is transfused to, switching system stops that call waiting signal is sent to it and calls out the user (step S4-4) who is waited for, all user sides then, i.e. conferencing function user, another user and wait for that the user interconnects are so that all user sides carry out conference communication (step S5).
Thereby, can carry out key operation and in the process of carrying out telephone communication, add access customer one by one by user that the user adds function wherein is housed.In other words, a plurality of users communication that can participate in a conference.In addition, the user who does not need to participate in a conference can be ostracised outside meeting according to conferencing function user's selection.
According to conference communication of the present invention, delete in the step (step S7) the user shown in Fig. 3, if in the process of carrying out conference communication (step S2 or S5), imported key signals, then carry out and determine whether enter key is the interim step of user's removal request ID (for example being changed to ' ★ ').
In the case, be transfused to, delete step S7 just carry out the user if the user deletes ID.
In other words, switching system determines whether the user of input user removal request ID is provided with conferencing function user delete function.If, switching system just from meeting deletion with by conferencing function user and the corresponding specific user of removal request key requesting users sign indicating number, and allow other user to continue conference communication.
In other words, delete on the step S7 user of the present invention, if the user (conferencing function user) that user's delete function is housed is in turn by ' ★ ' key (user's removal request ID key), specific user's sign indicating number key and delete key (for example ' SEND ' key), switching system is carried out delete function by deletion from conference communication with the corresponding specific user of specific user's sign indicating number, turns back to meeting step S2 then.
Here, specific user's sign indicating number is that the order by the communication that participates in a conference provides, ' 1 ' user (conferencing function user) who gives at first to ask conference communication wherein, and ' 2 ' give to call out and coupled user by sending to the first request user.Specific user's sign indicating number is provided with in this wise, promptly provides sequence number with the user's order that participates in a conference.This user code can use when deletion user from conference communication.
Thereby, when using phone to carry out conference communication, the specific user who communicates by letter that participates in a conference is deleted the operation of key one by one by the conferencing function user, deletes the specific user who finishes preplanned mission during conference communication thus, the communication so that this specific user no longer participates in a conference.
In switching system (MSC), carrying out as shown in Figure 3 in the user's deletion/adding step during the conference communication of the present invention.As expression in detail in Fig. 6, when carrying out conference communication (step S2 or S5) by phone, if a key signals is input to MSC (step S6-1) from the conferencing function user, determine then whether enter key is conversion (deletion) key (for example ' ★ ' key), and when not being (step S6-2), carry out the operation that depends on this input key signal.But, be conversion key as determining this enter key, whether whether MSC will check corresponding translation function (delete function) to provide to this conferencing function user, finish thus being the check (step S6) that the user deletes ID key (delete key, for example ' ★ ' key).
After step S6-3, switching system is waited for, till user code to be deleted is imported from the conferencing function user (step S8-1), deletes corresponding user (step S8-2) when being transfused to if reach corresponding sign indicating number (user code to be deleted).Then, if desired, determined whether to import call number to be added, and if do not import call number to be added and will proceed conference communication (step S8-3).If imported call number to be added, switching system control produces call waiting signal (step S8-4) simultaneously to all conferencing function users, and allows to communicate (step S8-5) by the user who connects the additional input call number.MSC will wait for, till pressing the essential any transmission key (for example ' SEND ' key) that is used for conferencing function, promptly MSC will wait by the time received (step S8-6) till ' SEND ' key signals.If pressed the transmission key, all users just are connected, so that the user who waits for and the user of adding carry out conference communication (step S8-7) together, finish user's deletion/adding step S8 thus.
Here, conferencing function user code in step S8-1 is to provide with the user's order of communicating by letter that participates in a conference, ' 1 ' user (conferencing function user) who gives at first to ask conference communication wherein, and ' 2 ' give to call out and coupled user by sending to the first request user.Specific user's sign indicating number is provided with like this, so that sequence number provides with the user's order that participates in a conference.
At this moment, if do not import ringing number to be added, will in not deleted existing conferencing function user, proceed conference communication (step S8-3).If imported ringing number to be added, then in not deleted existing conferencing function user, proceed conference communication, and the conferencing function user who call waiting signal is sent to other to be keeping all users, but is equipped with except the conferencing function user of conferencing function and these two kinds of functions of user's deletion/adding function.Then, the user of additional input call number and conferencing function user are connected, so that carry out telephone communication (step S8-5) between this two side.
In the case, if the conferencing function user is by sending signal key (for example ' SEND ' key) (step S8-6), the existing conferencing function user of all waits connects (step S8-7), so that each side carries out conference communication.
Thereby, can in the process of carrying out conference communication, delete specific conferencing function user and add other user to carry out conference communication.During conference communication, can delete unnecessary user and add necessary user to carry out conference communication.
