Voice plays call right(Rise and exhale instruction)
Voice end call right
There are business option and the major class of start and end call right two in list, when the type of this business is present in the business option of list simultaneously and meets start and end call right, then it is assumed that this business meets the requirement of service authority, can allow.
Fig. 2 is the flow chart that the present embodiment realizes the mobility limitation based on business, is comprised the following steps:Step 201, the scope covered to mobile network, pre-sets several restricted area, and the mapping table that each restricted area in its coverage includes cell with the restricted area is configured in MSC.In attaching position register(HLR in), the logical identifier of its several restricted area registered and corresponding service authority list is preserved for each user, is stored in customer data base;
Step 202, when mobile terminal is registered, during such as start or when being moved to another MSC institutes control area, to base station controller(BSC registration message) is sent(Corresponding to the step 301 of the Signalling exchange flow shown in Fig. 3), BSC is again to MSC/VLR (mobile switching center/visitor location registers)Send position updating request(Corresponding to step 302), VLR sends registration notification request message to HLR(Corresponding to step 303), HLR is according to the mark for the MSC for sending request message, and the restricted area related to the MSC for taking out mobile terminal registration (includes user and be currently located the limit that MSC controls cell Area processed)And its corresponding service authority list, with the business list data in the user common service area together, VLR (corresponding to step 304) is returned in enrollment response message, is preserved in the local database by VLR, then MSC/VLR returns location updating response to BSC(Corresponding to step 305), BSC returns registration received message to mobile terminal again(Corresponding to step 306);
Step 203, when mobile terminal carries out business operation, including rise and exhale, exhale and switch eventually, report the multiple pilot signals of the intensity that receives more than T-ADD;
If BSC only indicates that mobile terminal works as previous cell in service message, the mobile terminal positioned at two abutting subdistricts can be caused, even if position is constant, due to the fluctuation of on-air radio signal, the signal intensity of adjacent cells is more than current area, so as to which different cells may be carried in service message, the business of user is caused to be rejected.To solve this problem, when mobile terminal carries out business operation, multiple pilot signals of the intensity received more than T-ADD are reported, the cell that the corresponding cell of the plurality of pilot signal is all currently located as mobile terminal can so increase the possibility that business is allowed to.
Step 204, above-mentioned pilot signal is converted into cell list, and be sent to MSC by service message by BSC according to configuration;
Step 205, MSC finds the mobile terminal obtained from VLR in the restricted area of the business list of common service area and its registration and the list of correspondence service authority, to each restricted area, its one group of cell included is obtained from the mapping table of configuration, compared with the cell list obtained from service message, if both have coincidence, illustrate that mobile terminal is located in the restricted area.After completeer to each restricted area, judge whether mobile terminal is located in one or more restricted area of its registration, if it is, performing step 206, otherwise, perform step 207;
Step 206, MSC is according to mobile terminal present type of service and one or more restricted area at place, the list of the restricted area registered using mobile terminal and corresponding service authority, examine service authority of Check this business of mobile terminal in each restricted area, if this business is allowed in some restricted area, then it is assumed that this business is allowed to;Otherwise, if in all restricted area, this business is without authority, then it is assumed that this business does not allow, and performs step 208;
Step 207, when multiple cells in service message are not located in the restricted area that any user registers, MSC is checked the authority of this business of mobile terminal using the business list in common service area; Step 208, MSC judges whether this business of user is allowed to, if it is, performing step 209, otherwise, performs step 210;
Step 209, this flow is jumped out, continues normal operation flow, is terminated;
Step 210, to different types of service, different operations are performed:Exhaled for voice, circuit type data service rises and exhaled, in a suitable form(Such as voice)Discharged after prompting the user with;Exhaled eventually for voice, Packet data service rises and exhaled, in a suitable form(Such as short message)Discharged after prompting the user with;For the switching of conversation state, in a suitable form(Such as short message, Flash) prompt the user with, timer is set(Timer duration is that 0 expression is not to wait for, and is discharged immediately)Wait, if user returns to business before timer expiry and allows area, remove timer and continue normal business, otherwise discharged after timer expiry;For other types of service, discharge immediately.
It can be seen that from above-mentioned flow, with the present embodiment method, generally, VLR just needs to interact with HLR only when starting shooting or being moved to another MSC institutes control area, thus while the mobility limitation using cell as least unit is realized, network load will not be impacted.
Fig. 4 is that mobile terminal carries out the schematic flow sheet that voice acts execution mobility limitation when exhaling, and illustrates that calling mobile terminal acts situation when exhaling and occur because of movement cell switching.Wherein MSC/VLR processing rises to exhale for circuit type data service acts the equipment for exhaling the Other in all same, figure to represent called side with Packet data service.Comprise the following steps-step 401, mobile terminal rises and exhaled, and BSC sends service request to MSC;
Step 402, MSC sends assignment request to BSC;
Step 403, BSC is the resources such as mobile terminal assignment air traffic channels, after the completion of, refer to match somebody with somebody completion message to MSC;
Step 404, the pilot signal that the intensity of mobile terminal reporting is more than T-ADD is converted into corresponding cell identification list by BSC, and MSC is sent to by handoff completion message specified in standard;
Step 405, MSC uses the cell list, the restricted area list registered with reference to the user and restricted area and the corresponding relation of cell of configuration, obtain all restricted area that mobile terminal is currently located, if mobile terminal is located in one or more restricted area, then checked respectively using the service authority of these restricted area, as long as in some restricted area there is authority can allow this business;If mobile terminal not position In in any restricted area, then authority is judged using the business list in common service area.In this example, it is assumed that business is allowed to, continue to call to called set up;
Step 406, access success continues, called terminal ringing;
Step 407, called party answer;
Step 408, calling and called both sides enter talking state; '
Step 409, calling mobile terminal is moved, and occurs cell switching in conversation state, and BSC sends handoff completion message to MSC;
Step 410, MSC uses the cell list in handoff completion message, judges whether mobile terminal has service authority in the cell list switched using the method same with step 405.In this example, it is assumed that no service authority, then MSC is prompted the user with using short message or other modes, sets timer to wait;
Step 411, MSC is judged before timer expiry, and mobile subscriber, which does not switch back into business, allows region, then notifies called and BSC to remove calling;
Step 412, BSC is returned to MSC and is removed completion message.
Fig. 5 ' is the schematic flow sheet that mobile terminal performed when voice is exhaled eventually mobility limitation.Wherein MSC/VLR processing exhales all identical for the end of packet-type and circuit type data service, the equipment that the Other in figure represents caller side, as illustrated, the flow comprises the following steps:
Step 501, some fixed telephone subscriber calls the mobile terminal, and MSC receives the call setup message that other interchangers are sent;
