    Best Mode for Carrying Out the Invention Hereinafter, embodiments of the invention will be described with reference to the drawings.
    The present invention provides a method for allocating dispensing areas, which can meet the requirements for performing the service functions, such as indication for outside the dispensing area, service area selection and etc. a trunk system. The method for allocating dispatch areas in a CDMA trunk system is provided by the present invention which relates to a trunk system network consisting of PDS (PTT dispatch server), PDC (PTT dispatch client), BSS (base station system) and PHR (PTT home register). ), as shown in Figure 1, wherein the method comprises the following steps: step 101, a base station system divides a service area into DLA (dispatch location area) according to the geographical location, wherein the DLA may comprise one or more cells and does not overlap. geographically and each DLA is unique under a single PHR, step 102, assigns DSA (dispatch server area) for each fleet on the PHR, said DSA comprising a DLA or a plurality of DLAs and acting as a work area for said fleet , 535 TQE step 103, allocates dispatch service area for groups of said fleet, whereby dispatch service areas of the groups would be the whole set or is a subset of the dispatch server area of the fleet, step 104, synchronizes dispatch area information from the network side to the mobile station by updating user information, step 105, creates system parameter message at the base station to have the dispatch location information (DLA) to which this cell belongs, for to inform whether the mobile station is outside the dispatch service area.
    Figure 2 shows a network structure diagram of the trunk system for realizing the arrangement of the dispensing area.
    It can be seen from the figure that the entire network consists of forwarding server 203, forwarding client 202, base station system 201 and PTT home register 204. Base station system 201 is connected to forwarding client 202 via interface A8d / A9d, where A8d carries service traffic and A9d carries signaling. the forwarding client 202 is connected to the forwarding server 203 via the Al0d / Alld interface, where Al0d carries service traffic and Alld carries signaling. The PDS 203 and the PHR 204 are connected to each other via RADIUS (remote authenticated call user service) interfaces, the PHR mainly storing trunk user information and performing authentication, authorization and accounting.
    Figure 3 shows the diagram of the procedure for allocating dispatch areas at the base station side.
    In the figure, each hexagon indicates a cell and BSC1 and BSC2 belong to a single PHR. It can be seen from the figure that the DLA may comprise a cell or a plurality of cells and does not overlap geographically under a single PHR. DSA for a fleet may include a DLA or multiple DLAs. Furthermore, the DLAs included in a DSA for a single fleet may or may not be contiguous, or they may also belong to different BSCs. For example, the fleet DSA may either include DLA1 and DLA4 simultaneously or include DLA2 and DLAS.
    Figure 3 shows a diagram in which a user of a fleet makes a trunk call; the process by which the user performs a truncation call includes the following steps: Step 301, start.
    Step 302, the base station receives a calling call message sent from a mobile station and transmits it to a forwarding client.
    Step 303, the forwarding server requesting the PHR (PTT Home Register) for authorization upon receipt of a PTT call request message.
    Step 304, the PHR sends an "authorized" message to the PDS, the authorized message containing information about a group and the group information including DSA (dispatch server area) for the group.
    Step 305, the PDS judges whether or not the DLA of the cell as the calling call belongs to the DSA of the group; by going through the normal call procedure 306 in the case of "yes", and going through the release procedure 3061 in the case of nne fi u.
    Step 306, the PDS sends a call set-up request message to the creator and a call search message to all terminators of the PDC, the search message for the terminators containing DSA information for the group.
    Step 3061, sends a call rejection message to the PDC and the reason for rejection is that the creator is outside the distribution area.
    Step 3062, the base station sends a release message to the creator.
    Step 3063, after receiving the release message, the creator shows on the screen that the reason for the call set-up failure is that the call is created outside the forwarding area.
    Step 307, the base station searches for the terminators within the dispatch service area.
    Step 308, the base station establishes radio resources for the group and informs the PDS that the call set is complete.
    Step 309, the PDS authorizes the creator to speak, the group talk set is complete and trunk talk begins.
    The performance of the trunk area function in a trunk network provided by the present invention effectively reduces the load on search channels, realizes the important trunk functions, such as service area selection, out-of-bounds area indication, etc. in a convenient manner and provides a flexible allocation area allocation method.
    Of course, this invention can be realized with a number of other cases, where one who is technically proficient in the field can make any changes or corresponding exchanges without departing from the spirit and essence of the invention, but the corresponding changes of this invention should be under the protection of the requirements of the rights claimed.
    Industrial Applicability The present invention divides the service area of the base station system into a plurality of dispatch site areas that do not overlap geographically and allocates one or more of said dispatch site areas as dispatch service area to each fleet to cause dispatch service areas of a group to be said vehicle. a whole set or a partial set of said dispatch service area for the fleet, thus the dispatch service area function is realized in a trunk network, it can reduce the load of search channels effectively, perform the important trunk functions, such as area selection, indication of outside and dispatch area etc. provide a flexible procedure for allocating service areas for fleet forwarding. The method of the present invention is applicable to the field of dispatch service area device in a trunk communication system according to the standard code division multiple access.
