Abstract
The invention discloses a method for identifying geographic locations of mobile terminals. The method includes that firstly, the mobile terminals receive and read broadcast channel information and acquire location area identification codes; and secondly, the geographic locations of the mobile terminals can be identified according to the location area identification codes. The mobile terminals can actively quickly identify geographic locations thereof and synchronize time zones, and accordingly, quick network registration of the mobile terminals can be realized according to relevant network information corresponding to the geographic locations.
Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the geographic location recognition methods of a kind of portable terminal.
Background technology
Portable terminal is leaving this area or this country, can continue to use in another area arrived or country, and this process is promptly roamed.Roaming can only be compatible at network formats and the domestic city of having networked between or signed between area or the country of bilateral roaming agreement and carried out; Portable terminal is through after being registered to the signatory network of location or country again, the service that can use this Virtual network operator to provide.
In the prior art, portable terminal can be attempted in its all-network that can insert, registering after arriving another area or country, owing to possibly have not signatory situation in its all-network that can insert, the unsuccessful situation of registration promptly occurs.Wasted the time that successfully is registered to new network and uses its service like this, undoubtedly.In addition, possibly there are the time difference in new network's coverage area that portable terminal arrived and the network's coverage area that belongs to before it, also do not have portable terminal time zone update mechanism initiatively at present.
Summary of the invention
The technical problem that (one) will solve
The technical problem that the present invention will solve is: provide a kind of mechanism of active identification of geographic location that can be through portable terminal to save it and land and the portable terminal geographic location recognition methods of time of registered network.
(2) technical scheme
For addressing the above problem, the invention provides the geographic location recognition methods of a kind of portable terminal, comprise step:
S1. portable terminal receives and reads broadcast channel message, and obtains the lane place identification code;
S2. discern the geographical position at said portable terminal place according to said lane place identification code.
Preferably; In step S2; Through said lane place identification code being comprised part or all of number and ownership place question blank to recently discerning the geographical position at said portable terminal place, said ownership place question blank is the tabulation in the part or all of number that comprised of said lane place identification code and corresponding geographical position thereof.
The information of the network that preferably, also comprises each geographical position in the said ownership place question blank and covered.
Preferably, said ownership place question blank is stored in the said portable terminal.
Preferably, in step S2, also comprise time zone and the prompting renewal of confirming the current place of said portable terminal according to said broadcast channel message.
Preferably, said broadcast channel message comprises BCCH message, comprises said lane place identification code in the said BCCH message.
Preferably, said broadcast channel message also comprises Sync Channel Message, in step S2, confirms the time zone at the current place of said portable terminal and points out renewal according to the positional information that is comprised in the said Sync Channel Message.
Preferably, said portable terminal is the single mode portable terminal that is operated in the GSM network, or comprises the multi-module mobile terminal of GSM network for job network.
(3) beneficial effect
Method of the present invention can realize portable terminal identification of geographic location initiatively and fast, and time zone synchronously, thereby can realize registered network apace according to the pairing network of relation information in this geographical position.
Description of drawings
Fig. 1 is the portable terminal geographic location recognition methods flow chart according to one embodiment of the present invention.
Embodiment
The portable terminal geographic location recognition methods that the present invention proposes is described with reference to the accompanying drawings as follows.
Method of the present invention especially is applied in the single mode portable terminal that is operated in the GSM network, or job network comprises on the multi-module mobile terminal of GSM network.As shown in Figure 1, the portable terminal geographic location recognition methods that accordings to one embodiment of the present invention comprises step:
S1. portable terminal receives and reads broadcast channel message, and obtains the lane place identification code.
Portable terminal from this area or this country leave and arrive another area or when national,, then in powering up start process, receive and read GSM broadcast channel (BCH) message if be in off-mode; If be in open state, then at first will lose the signal of former network, receive and read the GSM broadcast channel message again.
S2. portable terminal is according to the geographical position at lane place identification code (LAI) identification portable terminal place.Particularly, through part or all of number that LAI is comprised and ownership place question blank to recently discerning the geographical position at portable terminal place.Wherein, LAI comprises mobile national number (MCC), moves network No. (MNC) and lane place number (LAC), also is that the number structure of a string LAI is: LAI=MCC+MNC+LAC.The ownership place question blank is the tabulation in the part or all of number that comprised of lane place identification code and corresponding geographical position thereof, and the ownership place question blank is stored in the portable terminal.In addition, also comprise the network information that covers the corresponding geographical position in this tabulation, the information of subscription network especially, thus objective network can registered and be registered to portable terminal targetedly, shortened the time of registered network.
This BCH message comprises: frequency correction channel (FCCH) message, synchronizing channel (SCH) message and BCCH (BCCH) message, and this LAI is included in the BCCH message.In addition, in step S2, portable terminal also can be confirmed the time zone at the current place of portable terminal and point out the user to upgrade according to the positional information that is comprised in the SCH message.
Above execution mode only is used to explain the present invention; And be not limitation of the present invention; The those of ordinary skill in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
Claims (8)
