Description
The present invention relates to the communication technology, more particularly, relate to a kind of method of in digital micro-honeycomb communication system (comprising that commercial PBX, wireless local loop, cordless terminal move CTM application etc.), upgrading the mobile telephone position register information on the cluster controller (BSC) based on the DECT technology.
DECT (Digital Enhanced cordless Telecommunication) standard is the digital micro-honeycomb communication standard of ETSI in issue in 1992.Multi-access mode that DECT employing FDMA/TDMA combines and the ADPCM speech coding of 32Kbps are supported bi-directional call and seamless handoff, have the ability of handling high traffic density; It not only supports voice service, also can support the data service up to 552Kbps; DECT also provides the interface with networks such as ISDN, X25, GSM, and DECT unique technique advantage and characteristics have determined it can support to comprise the multiple application of family expenses, commercial PBX, wireless local loop, CTM etc. to have vast potential for future development.
What DECT adopted in actual networking is the notion of microcellulor.The coverage of each base station (BS) is a sub-district (cell), and several cell constitute one bunch (cluster), all bunches of coverages of just having formed whole system.
Fig. 1 has illustrated this bunch control hierarchy.As shown in the figure, the position of each mobile phone and state information all are to be registered on the affiliated cluster controller (BSC), a table is arranged on each cluster controller (BSC), the details of record all mobile phones (as base station A1-A3 under the cluster controller A) in the prevariety scope, when (for example from base station A1 to base station A2) between the different base station of mobile phone under same bunch when mobile, needn't do location registers; When mobile phone moves in the base station scope of another bunch from one bunch base station scope, just should do location registers (for example from base station A3 to base station B1) automatically.And the table of the record mobile phone state in the switch such as location registers table are also bunch being unit, when certain cellphone subscriber of calling of switchboard, also be that call request is sent on the corresponding cluster controller, broadcast on each base station by cluster controller, this mobile phone of paging, if called mobile phone still will be reacted, finish the process of incoming call in bunch coverage; If called mobile phone not in bunch coverage, will cause the incoming call failure owing to paging is overtime.So the correctness of the mobile telephone position register information on the maintenance cluster controller and promptness have crucial effects for the incoming call call completing rate that improves system.
It all is to abide by ETSI GAP agreement that the design of DECT mobile phone is at present produced.This agreement has stipulated that mobile phone inserts necessary process of PSTN and element.According to GAP; mobile phone power-on and when arriving new bunch, should initiate location registers; promptly this mobile phone and positional information thereof are reported switch by BSC; as in switch, there not being corresponding register information; then register with the understanding of maintenance, but just do not have safeguard measure for situations such as mobile phone sudden power, mobile phone shutdowns to movable mobile phone state.After that is to say mobile phone shutdown or sudden power, cluster controller and switch also do not know, so for the incoming call of this mobile phone, cluster controller will carry out paging, reports switch incoming call failure after overtime.The consequence that causes like this is that the calling subscriber will just can hear the voice suggestion of call failure after waiting for certain hour, makes service performance not ideal enough.
The object of the present invention is to provide the method for the mobile telephone position register information on a kind of renewal cluster controller (BSC), make switch and cluster controller obtain the mobile telephone position register information that regularly upgrades, avoid unnecessary paging, the success rate of raising system incoming call, minimizing calling subscriber's stand-by period.
