Abstract

The method comprises: when a member not capable of accessing the system when call is established is provided with the access condition, he informs the scheduling server; the scheduling server enquiries the call state where said member locates at; if there is a only one group being in calling state, makes paging for said member to let him participate the group; if there are multi groups being in calling state, the scheduling server gets the priority of group, and selects a group with highest priority, makes paging for said member to let him participate the selected group; said member responses the paging, establishes the call, joins the group and starts to listen in the speech sound.

Description

A kind of method that realization lags and inserts in trunking communication

Technical field:

The present invention relates to a kind of method that realization lags and inserts in trunked communication system, relate in particular to digital cluster communication based on CDMA (Code Division Multiple Access).

Background technology:

Trunking communication is an important branch of radio communication, is mainly used in professional moving communicating field.Trunked communication system based on CDMA (code division multiple access) technology then combines CDMA technology and specific schedule communication system, both expanded the scope of business of cellular communication system, and made trunked communication system break away from the specific-dispatching communication system again in function and regional limitation.CDMA group system network is made up of equipment such as colony terminal, base station system/dispatching client and dispatch servers.

In the common cdma communication system, if a side can't insert when call setup, this call failure; And in trunked call, as long as comprise that two users of caller successfully insert in the group calling, even if this time call out success.Other users that temporarily fail to insert also can join in the group calling after possessing access conditions automatically, are called the access that lags.

Summary of the invention:

To be solved by this invention is to realize the function that lags and insert in the trunked call.For achieving the above object, the step of call prompt of the present invention comprises:

Step 1, the member that can't insert when group calling is set up have possessed access conditions, register to dispatch server;

Step 2, dispatch server are received after the registration, inquire about the talking state of the group at this member place, if when having only a group conversing, this member of paging joins in this group; If when having a plurality of groups conversing, dispatch server obtains group's priority, select the highest group of priority, this member of paging makes it join the highest group of priority.

Step 3, this member respond paging, set up and call out, and join in this group, can begin to listen to speech.

Described can't the access comprises this member's shutdown when group calls in several is set up, or out of reach, or is in other same priority or the high-priority service, and temporarily can't insert.

Described possessed access conditions and comprised that simultaneously this member enters service area, starts shooting, is in Idle state, successfully registers four conditions to dispatch server.

Described group priority is definite when distributing telephone numbers.

Adopt the method for the invention, compared with prior art, realized that the member that can't insert when group calling is set up has possessed the function that inserts at once behind the access conditions, make the trunked call function more powerful, more adapt to the needs in market.

Description of drawings:

Fig. 1 is the flow process that lags and insert of starting up of terminal registration;

Fig. 2 is the flow process that terminal enters the access high-priority call that lags after service area is registered;

Execution mode:

Enforcement below in conjunction with a pair of technical scheme of accompanying drawing is described in further detail:

MS1 in the accompanying drawing 1, MS2, MS3 is among the group that the coexists A.

Step a:MS1 is in off-mode;

Step b: group calling A sets up;

Step c:MS1 start;

Steps d: MS1 sends the start registration through BS to PDS (PTT Dispatch Server dispatch server, wherein PTT refers to PushTo Talk);

Step e:PDS receives after the start registration of MS1, inquires the affiliated group calling A of MS1 and converses;

Step f:PDS is through BS paging MS1;

Step g: MS1 joins among the group calling A.

Enforcement below in conjunction with two pairs of technical schemes of accompanying drawing is described in further detail:

MS1 had both belonged to group A and had also belonged to group B in the accompanying drawing 2, and MS2 belongs to group A, and MS3 belongs to group B.

Step a:MS1 is in outside the service area;

Step b: group calling A sets up, and comprises MS1 in this group;

Step c: group calling B sets up, and also comprises MS1 in this group;

Steps d: MS1 enters service area

Step e:MS1 initiates registration through BS to PDS;

Step f:PDS receives after the registration of MS1, inquires MS1 affiliated A of group and the B of group and converses, and through inquiry priority, distinguishes the priority height of the A of group;

Step g: PDS is through BS paging MS1, and instruct MS 1 adds the A of group;

Step h:MS1 joins among the group calling A.

Adopt this kind method, can make because out of reach or not have start and user that temporarily can't access group calling can insert at once after entering service area or starting shooting, enrich the function of trunked call more, adapted to the needs in market, improved user's satisfaction.

Claims

1. method that realizes lagging and inserting in trunking communication is characterized in that this method may further comprise the steps:

1.1, the member that can't insert when group calling is set up possessed access conditions, register to dispatch server;

1.2, dispatch server receives after the registration, inquires about the talking state of the group at this member place, if when having only a group conversing, this member of paging joins in this group; If when having a plurality of groups conversing, dispatch server obtains group's priority, select the highest group of priority, this member of paging joins in the highest group of priority it;

1.3, this member responds paging, sets up and calls out, and joins in this group, can begin to listen to speech.

2. method according to claim 1 is characterized in that, the described member that can't insert of step 1.1 is meant this member's shutdown when group calls in several is set up, or out of reach, or is in other same priority or the high-priority service and can't inserts.

3. method according to claim 1 is characterized in that, step 1.1 is described have been possessed access conditions and comprise that simultaneously the member enters service area, starts shooting, is in Idle state, successfully registers four conditions to dispatch server.

4. method according to claim 1 is characterized in that, the described group of step 1.2 priority is definite when distributing telephone numbers.
