Abstract

The invention discloses an active delay access method used in a trunking communication system, which comprises that: a trunking terminal launches a trunking calling request to groups which want to access; a base station system transmits the received trunking calling request to a trunking dispatching server which requests authentication to a trunking dispatching home location register; after the trunking calling request is authenticated, the trunking dispatching server notifies the base station system to distribute channel resources for the terminal; the trunking terminal constructs service channel access groups according to the channel resource information distributed by the base station system. The method leads the trunking terminal to access the trunking calling extremely rapidly and actively, thus greatly simplifying the procedures and saving time.

Description

Active delay access method in a kind of trunked communication system

Technical field

The invention belongs to the digital cluster communication technical field, relate in particular to the method that lags fast and insert of a kind of code division multiple access CDMA (Code Division Multiple Access, code division multiple access inserts) standard group communication system.

Background technology

Trunked communication system based on mobile communication is that cellular telecommunication art and specific schedule communication system are combined, and adopts the communication system of half-duplex operation mode, can realize continuing fast, supports group call (being the method for calling of one-to-many).Such trunked communication system can be widely used in the departments of commanding, scheduling feature is had relatively high expectations such as enterprises and institutions, public security, police and army.

So-called group call is one of service feature important in the group system, method by reverse traffic channel before under the sector, sharing, provide that (group can comprise hundreds of user terminal to big capacity group among a small circle, user terminal in the present invention also can be referred to as colony terminal, and these colony terminals all are positioned under among a small circle the sector) the support of group call.Every other colony terminal is conversed simultaneously in the colony terminal that allows to have right of speech in group call and the group, that is to say in the group that except the colony terminal of speaking, other colony terminals must all listened to.

The special character that trunking communication makes a call is: owing to need the colony terminal of calling numerous, be difficult to guarantee that all colony terminals of per call all one insert surely, therefore may exist the called colony terminal of part can not insert in the very first time, most of group systems access function that all lags because of cause specific.The general implementation method of the so-called access function that lags is ceaselessly to send beep-page message by group system to the colony terminal that does not insert, and is embodied as the access function that lags that inserts the user, the promptly passive access that lags.But for the consideration of air resource, the also free restriction at interval of the repeating transmission of beep-page message, during this time every in, the colony terminal of Jie Ruing can initiatively not make a call and add already present cluster group, i.e. the active access that lags.For the method that initiatively lags and insert, the processing mode of system generally is that group system sends message earlier at present, discharges the colony terminal that initiatively lags and insert, after colony terminal is released, send call message by colony terminal again, this colony terminal is inserted by the passive flow process that inserts that lags.

Present active lags the method idiographic flow that inserts as shown in Figure 2:

Colony terminal in 201-202, the group initiates initiatively to lag to insert request, and call message is sent to trunking dispatch server by base station system.Trunking dispatch server is judged the call message of this colony terminal, converses if find this group call, sends call rejection message to the access set group terminal that initiatively lags.

203, base station system timed sending shared channel resources information, the access set that initiatively lags group terminal receives this information, and sets up shared channel resources.

204-205, initiatively lag after the access set group terminal insert to call out, send the right of speech request to trunking dispatch server, trunking dispatch server loopback right of speech information is given colony terminal.

Though the function that said method equally can be realized lagging and insert, interacting message is many, and the passive access process that lags is obviously slow than normal access on access speed, may also can't satisfy user's requirement in actual applications.

Summary of the invention

Technical problem to be solved by this invention is: in the process that trunked call is being conversed, for some reason, when initiating such as trunked call terminal do not start shooting, colony terminal midway initiatively or passive withdrawing under the situation such as trunked call, this type of trunking terminal user can be by dialing cluster number this trunked call group of access very fast and initiatively of conversing.

The technical scheme that solution the technology of the present invention problem is adopted is:

The active delay access method comprises the steps: in a kind of trunked communication system

1), colony terminal is initiated the trunked call request to the group that desire inserts;

2), base station system is transmitted to trunking dispatch server with the trunked call request of receiving, trunking dispatch server is carried out authentication to the request of colony dispatching home location register;

3), described trunked call request is by after the authentication, trunking dispatch server informing base station system is described terminal distribution channel resource;

4), described colony terminal inserts group according to the channel resource information structuring Traffic Channel of base station system distribution.

Further, the trunked call request of described terminal initiation is a group calling message.

After described trunked call request is by authentication, further comprise step 3a):

Whether trunking dispatch server allows terminal to insert according to the word right situation decision of current group, if current group word right situation inserts for not allowing terminal, terminal is in waits for the right of speech formation, and be to allow terminal to insert until current group word right situation.

At described step 3a) also further comprise afterwards:

3b), after base station system receives the message of trunking dispatch server, judge according to group identifier whether described group has assignable resource, if having, then construct a resource description message that includes right of speech information and send to terminal; If no, then redistribute resource and give terminal, construct a resource description message that includes right of speech information and send to terminal.

Wherein, described terminal is then refused terminal and is inserted process ends during as the authentication of failing by the colony dispatching home location register.

Adopt the technique effect that technical solution of the present invention produced to be: in the process that trunked call is being conversed, for some reason, when initiating such as trunked call terminal do not start shooting, terminal midway initiatively or passive withdrawing under the situation such as trunked call, by can obviously finding out with the comparative analysis of background technology, this type of user can described method initiatively this trunked call of access very apace, simplify flow process widely, saved the time.

Embodiment

Below in conjunction with accompanying drawing specific embodiments of the invention are described in detail:

As shown in Figure 1, the network configuration of present group system based on CDMA is by constituting with lower module: colony terminal, base station system system, trunking dispatch server and cluster home location register are formed.Colony terminal mainly provides to user's communication and uses, and also can be referred to as cluster mobile telephone, and colony terminal is realized communicating by letter with the base station system system by eating dishes without rice or wine, and described each base station system system concentrates with trunking dispatch server and communicates.Network architecture for trunked communication system belongs to prior art, is not further detailed in embodiments of the present invention.

Technical scheme specific implementation of the present invention is:

1), terminal initiates the trunked call request to the group that desire inserts, the trunked call request that wherein said terminal is initiated is a group calling message.

2), base station system is transmitted to trunking dispatch server with the trunked call request of receiving, trunking dispatch server is carried out authentication to the request of cluster home location register, described colony dispatching home location register is carried out authentication to described trunked call request, described terminal is during as the authentication of failing by the colony dispatching home location register, then refuse terminal and insert process ends.

3), described trunked call request is by after the authentication, trunking dispatch server informing base station system is described terminal distribution channel resource, and notifies terminal by described base station system;

4), the message constructing Traffic Channel returned according to base station system of described terminal, insert group, judge self talking state according to right of speech information simultaneously, begin conversation or wait.

In the described step 3), after described trunked call request is by authentication, further comprise step 3a): whether trunking dispatch server allows terminal to insert according to the word right situation decision of current group, if current group word right situation inserts for not allowing terminal, terminal is in waits for and the right of speech formation be the access of permission terminal until current group word right situation.

Described step 3a) also further comprise afterwards:

The present invention directly judges the user's speech privilege state by dispatch server, and in conjunction with the direct judgement of base station system to resource allocation, initiatively lagging the user who inserts can be with minimum interacting message, and the fastest speed inserts current group call.

The present invention is further illustrated below by example:
