Description
Technical field
The present invention relates to the digital cluster communication field, more specifically, relate to a kind of busy calling forwarding method, be used for realizing calling forwarding on busy of traditional terminal in digital clustering communication system.
Background technology
In recent years, the Digital Clustering technology has obtained development apace, and digital clustering communication system becomes an important branch of mobile communication system day by day, is progressing into the daily life of ordinary consumer.Along with popularizing of the development of Digital Clustering technology and application, digital cluster system basic call such as group calling, the individual calling business efficiently that not only needs to provide convenience needs also to provide that kind is abundant, the supplementary service of complete function, thereby satisfies user's individual demand.Calling forwarding on busy is exactly a kind of in numerous supplementary services, and the user provides call transfer service in calling in order to be in for it, thereby guarantees that the user also can accept the group system service when being in busy condition.
In existing group system, the paging of user terminal is mainly contained dual mode, a kind of is to be the enhanced paging, and another is the traditional type paging.Wherein, carry specific user's terminal iidentification in the enhanced beep-page message, when user terminal response enhanced paging and after inserting calling, can send the message that pages reply to system, show that it has inserted calling, and carry the group identification of particular demographic in the traditional type beep-page message, and when the traditional paging of the terminal response of user in the group and after inserting calling, can be to any response message of system feedback.This shows behind the call setup, whether system can not know for sure has the user to respond the traditional type paging and insert calling.
Insert the mode of calling out according to group member in the group system, the group member can be divided into enhancement mode member and traditional member.So-called enhancement mode member, respond the enhanced paging exactly and insert the member of calling, for this class members, system knows clearly whether it inserts calling, and so-called traditional member, respond the traditional type paging exactly and insert the member of calling, for this class members, system does not also know whether it truly is linked in the calling.Because enhancement mode member and traditional member cause existing implementation method of calling forwarding on busy can't finish traditional member's the function of calling forwarding on busy realizing technical difference.
Fig. 3 is the flow chart of the traditional member implementation procedure of calling forwarding on busy.As shown in Figure 3, may further comprise the steps:
Step S301, PDS308 is in setting up new calling procedure, need calling user A302, so concentrated message table of inquiring user A302, obtain the current state information of user A302, if find user A302 current may be with traditional member's identity added certain conventional group calling in, then send traditional member condition inquiry request message to user A302;
Step S302, after user A302 terminal is received traditional member condition query requests, return traditional member condition inquiry response to PDS308, PDS308 just clearly knows that user A302 is current online in certain group like this, i.e. user A302 current " just busy ";
Step S303, PDS308 send the authentication request of calling forwarding on busy of user A302 to PHR310;
Step S304, PHR310 return the authentication responses of calling forwarding on busy of user A302 to PDS308;
Step S305, PDS308 sends the enhanced paging request message to the preceding commentaries on classics third party user B304 of user A302; And
Step S306, the terminal of user B304 is returned the message that pages reply to PDS308 after receiving the paging request.
Like this, just finished the flow process of calling forwarding on busy of both legacy users.Yet, in above-mentioned step S302, if (it represents that traditional member condition query timeout at interval to PDS308 in the time of expection, can be pre-configured) do not receive the traditional member condition inquiry response of user A302, then prove user A302 current " not being in a hurry ", like this, PDS308 just directly sends the paging request to user A302, does not just have follow-up step S303 to S306.
According to the handling process of Fig. 3, if the active user is A302 " not being in a hurry ", then also must after step S301 and S302, just begin paging A302, the time of user A302 access calling has just been prolonged greatly like this.
