Description
Technical field
The present invention relates to the automatic dial technology of mobile phone, particularly a kind of method of adding roaming IP number when roaming handset dialing automatically.
Background technology
GSM mobile termination (mobile phone) is registered as long as start just receives the operational factor of its base station, region whenever and wherever possible, and send this machine identification code and possession (or registered place) identification code to new base station.This answering is carried out automatically on the backstage, does not have demonstration on the screen and also need not user intervention.Can allow mobile phone that the base station operational factor is shown by the AT instruction, by base station identity code BSIC and the cell ID CI data of extracting, just can by GIS (GIS-Geographic Information System) system interface that operator provides know mobile phone current be somewhere.
Specific as follows:
Mobile communication system is the widest public communication systems of the maximum coverages of present user.The GSM net adopts cellular structure, and the area of coverage is divided into several sub-districts (Microcell even picocell), and the scope of sub-district varies according to user what and geographical environment; Big cell operation radius reaches more than ten kilometer, and little cell operation radius only has below hundred meters.
Each MSC comprises several lane place (LA), distinguishes each interior LA of MSC by lane place identification code (LAI); Each LA is divided into several base station areas again, generally is made up of several BSC; Be further divided into several cellular cells in the base station area, a base station is arranged in each cellular cell, when traffic carrying capacity increases, can carry out cell splitting, to satisfy the demand of traffic carrying capacity.Base station area in each LA district is distinguished by cell global identity (CGI=LAI+CI), and CI (Cell Identity) is a cell ID, is used to distinguish the sub-district in the LA district, uses 16bits at most.Yet the some cellular cells under the base station area are used for travelling carriage and discern adjacent different base station by BSIC (BaseStation Identity Code base station identity code) identification.Therefore need use CI and BSIC simultaneously.
Cell identification CI is used for each sub-district among unique expression PLMN, and CI is made up of two bytes, value between decimal system 0-65535, and cannot there be two identical cell IDs in the same position district.Base station identity code is a local colour coding distributing to the base station, makes travelling carriage can distinguish different adjacent sub-districts, sends during the sub-district on the synchronizing channel (SCH) of sub-district is described.BSIC one has 6 bit long, and its structure is as follows: BSIC NCC (network colour code)--Network Color Code, form by 3 bits, and be used to discern adjacent different GSM PLMN; In many cases, different GSM PLMN have adopted identical frequency resource, can also access network for travelling carriage in this case, and general adjacent GSM PLMN selects different NCC.BCC (BaseStation Colour Code)--BCC is made of the training sequence number of the base station that is used for discerning same GSM PLMN and notice travelling carriage BCCH 3 bits.BSIC comprises PLMN colour coding and BCC.Be used to distinguish different network operators or the identical different districts of same network operator's Broadcast Control Channel frequency.BSIC is used for the different base station of travelling carriage identification same carrier, be used in particular for distinguishing the base station of adopting same carrier and facing mutually in the forntier region of country variant, BSIC is a 6bit coding: BSIC=NCC (3bit)+BCC (3bit), be used for discerning the PLMN net BCC:BTS colour coding of facing mutually, be used for discerning the different base station of same carrier.
BSIC is mainly used in the sub-district that identical BCCH carrier frequency is used in difference, mainly contains following several situation:
, when travelling carriage asks to insert on RACH, adjacent sub-district might receive, and for fear of the generation of this situation, with RACH burst and this sub-district BSIC XOR mutually of encoding, has only the burst that decodes that correct sub-district just can be correct.
, notify the mobile playscript with stage directions sub-district training sequence TSC that common signaling channel is adopted, corresponding TSC is by the BCC decision of this sub-district.
3., under the connection mode, travelling carriage is gone up the regulation of relevant adjacent area table according to BCCH, measure, in up measurement report, for each beacon frequency, all need indicate corresponding BSIC, if adjacent sub-district has two or more to contain identical BCCH carrier frequency, then the base station can rely on BSIC to distinguish, and avoids wrong and switches.
4., travelling carriage is under connection mode, carry out up measurement report, only report and current area have the cell conditions of handoff relation really, and the NCC among the BSIC promptly is used for this purpose, and the network operator can only report NCC adjacent area situation in allowed band by " NCC that allows " control travelling carriage.
Gsm system all has sending and receiving base station and base station information processing center in each basic cellular cell.Manage and charge in order to realize mobile phone roaming communication and to be convenient to, the GSM net is provided with a cover user's location registers and a registration management system, and each base station all has dedicated channel to launch the network operation parameter of this base station.Network operation parameter comprises channel CH, base station identity code BSIC, data such as cell ID CI and signal strength signal intensity SS.And base station identity code BSIC and cell ID CI just corresponding the geographical position of unique this base station.
GSM travelling carriage (mobile phone) just receives the base station operational factor of region whenever and wherever possible as long as start shooting, and sends this machine identification code and original position ownership (registration) district identification code to new base station, registers.This course of work is mobile phone not showing of carrying out automatically also to need not user intervention.If being provided with AT, mobile phone instructs then that mobile phone can show the base station operational factor. we also available AT instructs the base station address code is extracted, weave into short message, send to another mobile phone (Surveillance center) by mobile phone, if user (Surveillance center) has the base station identity code of respective regions, base station address date handbook or cartographic information system, just know the actual present position and the state of front end mobile phone, perhaps CI and the BSIC that mobile phone extracts sent to this interface as input parameter by operator's geographical information system interface, obtain the city coded message, obtain the city title by city coded message table.
Summary of the invention
The object of the present invention is to provide a kind of method of adding roaming IP number when roaming handset dialing automatically.
A kind of method of adding roaming IP number when roaming handset dialing automatically, dynamically locate current city according to the base station address code information, whether the mobile phone of judging the user is in roaming state now, and the cellie needn't worry about effort, can be pursuits of the present invention for the user saves the communication rate.
Technical scheme of the present invention is as follows:
A kind of method of adding roaming IP number when roaming handset dialing automatically is characterized in that mobile phone determines by the GIS-Geographic Information System of base station identity code BSIC and cell ID CI and operator which city mobile phone is at present; Find the area code in this city according to city name; By area code that compares city, the current place of mobile phone and the area code that is stored in the mobile phone ownership place in the SIM card, judge whether mobile phone is in roaming state; If be in roaming state, then when dialing, add the roaming IP number that the appropriation family sets in advance automatically.
