Abstract
The invention discloses a method and a system for querying the status of a called party in paging, which are applied in a digital trunking communication system. The method comprises that: after a calling user initiates a voice call, a network pages a called user; if the called user participates in trunking call as a conventional member, the network sends a query request to the called user and learns that the called user accesses the trunking call from the query response fed back by the called user; and after learning that the called user accesses the trunking call, the network stops paging the called user and broadcasts a user busy prompt voice to the calling user. When the technical scheme of the invention is used, an exchange subsystem can acquire the status of a called party which is a conventional member through query.
Description
Technical field
The present invention relates to communication technical field, more specifically, relate to the method and system of inquiry called state in a kind of paging.
Background technology
Trunked communication system is a kind of mobile communication system that is used for group's dispatch control communication, is mainly used in professional moving communicating field, as public safety, communications and transportation, social interlock, municipal administration, hydraulic and electric engineering, industrial enterprise etc.Different with common mobile communication, the characteristics of trunking communication maximum are that Speech Communication adopts PTT (Push To Talk, PoC) button continues in a mode that pushes to talk, called need not can answering by off-hook, and the speed that continues is very fast, and can support functions such as group call.
The group system network configuration of correspondence of the present invention is seen Fig. 1, and each part is described as follows:
(1) terminal: possess the terminal equipment of group service function, also possess multiple business abilities such as interconnect call business, Packet data service, short message service simultaneously, can in the system whole-network coverage, roam.
(2) base station sub-system: finish the access function of terminal, and use type of service to distribute corresponding subsystem processes according to the user.
(3) switching subsystem: finishing control and function of exchange to terminal interconnect call business in its coverage, is the control centre of interconnect call business.Switching subsystem is by PSTN (PublicSwitched Telephone Network, PSTN) network interconnection.
(4) scheduler subsystem: finishing control and management function to termination set group business in its coverage, is the control centre of group service.Scheduler subsystem interconnects by IP network.
(5) grouped data subsystem: finishing control and access function to end packet data service in its coverage, is the control centre of Packet data service.The grouped data subsystem interconnects by IP network.
On the basis that above basic subsystem is formed, for abundanter business is provided, can also dispose the short message subsystem, parts such as intelligent network subsystem, positioning subsystem.
In the described group system, every class business (as interconnect call business, group service, Packet data service etc.) is all carried out control and treatment by corresponding subsystem (as switching subsystem, scheduler subsystem, grouped data subsystem etc.), and the roaming support of every class business all provides carrying by the interference networks between the corresponding subsystem.Interference networks between these subsystems with each regional group system, have constituted the group system network of network-wide basis, and the roaming support of all kinds of business of network-wide basis is provided for the user.
In the described group system, the composition structure of scheduler subsystem is seen Fig. 2, and each functional node is described as follows:
(1) dispatch server: realize the calling control and the right of speech management of trunked call.
(2) dispatching home location register: preserve the log-on message and the positional information of cluster user and group, realize authentication, mandate and billing function, and the position is upgraded and group management function to cluster user.
(3) dispatching desk server: safeguard the session of each dispatching desk, turnkey console, realize turnkey console and dispatching desk administering and maintaining to colony dispatching.
In scheduler subsystem, the paging mode of trunked call is divided into two kinds of traditional type paging and enhanced pagings by channel resource allocation mode difference.
Described traditional type paging is characterized by base station sub-system and does not distribute air traffic channel separately for each user, but is the shared air traffic channel of each group allocation.Because a group only is assigned the shared service channel in a sub-district, like this can be so that the number of members of single group is unrestricted.This kind paging mode and conventional cluster system are similar, so be referred to as the traditional type paging.
Described enhanced paging is characterized by the paging mode of base station sub-system by CDMA (Code Division MultipleAccess, code division multiple access) 2000lx normal voice calls, for each user distributes air traffic channel separately.Each user has oneself independently forward direction and reverse control channel, and finishes access procedure separately separately.Compare with the traditional type paging, respond this kind paging mode and the user that inserts calling can realize more supplementary service, so be referred to as the enhanced paging.
Correspondingly, member's identity is divided into two kinds of enhancement mode member and traditional members by paging mode difference in the trunked call.
Described enhancement mode member is meant the member who adopts enhanced paging mode.This type member is in case after inserting calling, base station sub-system can be notified the success of switching subsystem channel assignment, so switching subsystem knows that clearly it is in the trunked call busy condition.This type member is in case after inserting calling, base station sub-system can be notified scheduler subsystem paging success, so scheduler subsystem knows clearly whether it inserts calling.
Described traditional member is meant the member who adopts traditional type paging mode.This type member calls out even insert, and base station sub-system can not notified the success of switching subsystem channel assignment yet, so switching subsystem can't know that it is in the trunked call busy condition.This type member calls out even insert, and base station sub-system can not notified scheduler subsystem paging success yet, so scheduler subsystem can't know whether it inserts calling.
There are the following problems in the prior art: when audio call is initiated in caller, if it is called with traditional member's identity access set groupcall, then because switching subsystem can't be learnt called state, still can be to called transmission paging, behind paging failure, point out caller " called temporarily can't connect ", and in fact called just busy, thereby influenced the user experience of caller.
