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 through 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 the sector among a small circle) the support of group call.Every other colony terminal is conversed simultaneously in the colony terminal that in group call, allows to have words power 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 necessarily can insert; Therefore possibly 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 through 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 from the consideration of air resource, the also free restriction at interval of the repeating transmission of beep-page message, during this time at a distance from, the colony terminal that does not insert can initiatively make a call and add already present cluster group, access promptly initiatively lags.For the method that initiatively lags and insert; The processing mode of system generally is that group system is sent message earlier at present, discharges the colony terminal that initiatively lags and insert, after colony terminal is released; Sent by colony terminal again and exhaled message, this colony terminal has been inserted through the passive flow process that inserts that lags.

The present active method idiographic flow that inserts that lags is as shown in Figure 2:

Colony terminal in 201-202, the group is initiated initiatively to lag and is inserted request, rises and exhales message to be sent to trunking dispatch server through base station system.Trunking dispatch server exhales message to judge to rising of this colony terminal, converses if find this group call, sends call rejection message to the access colony terminal that initiatively lags.

203, base station system timed sending shared channel resources information initiatively lags and inserts this information of colony terminal reception, and sets up shared channel resources.

204-205, active are sent the power of word and are asked to trunking dispatch server after lagging and inserting colony terminal access calling, and trunking dispatch server loopback words power information is to 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, possibly 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 the 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 through dialing cluster number this trunked call group of access very fast and initiatively of conversing.

Solving the technical scheme that technical problem of the present invention 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), said trunked call request is through after the authentication, trunking dispatch server informing base station system is said terminal distribution channel resource;

4), said 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 said trunked call request is through authentication, further comprise step 3a):

Whether trunking dispatch server allows the terminal to insert based on the words power situation decision of current group, if current group words power situation inserts for not allowing the terminal, the terminal is in waits for the formation of words power, and words power situation inserts for allowing the terminal until current group.

At said step 3a) also further comprise afterwards:

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

Wherein, said terminal is then refused the terminal and is inserted process ends during like the authentication of failing through the colony dispatching home location register.

Adopt the technique effect that technical scheme 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 the terminal do not start shooting, the terminal midway initiatively or passive withdrawing under the situation such as trunked call, through can obviously finding out with the comparative analysis of background technology, this type of user can said method initiatively this trunked call of access very apace; Simplify flow process widely, saved the time.

Embodiment

Below in conjunction with accompanying drawing specific embodiment of the present invention is 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 through 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, does not do in embodiments of the present invention further to introduce in detail.

The concrete implementation of technical scheme of the present invention is:
