Description

The display packing of mobile terminal roaming designator and device
Technical field
The present invention relates to communication technical field, relate in particular to a kind of display packing and device of mobile terminal roaming designator.
Background technology
Portable terminal is after start, and search network can experience two processes, the one, system acquisition process, the 2nd, system identification process.
Portable terminal is after the system acquisition success, can enter the system identification stage, in this stage, whether portable terminal can relatively carry out system identification with the middle SID/NID that writes down of the middle System Records (system's table) of PRL (optimum roaming list) with SID among the Sync Channel MSG of system (Sync Channel Message) and NID (system banner and network identity), be the optimum decision system that portable terminal is provided with to determine the current system that catches.It is Roam Indicator (roaming designator) that an important content is arranged in System Records, and portable terminal determines whether showing that according to Roam Indicator roaming indication information notifies the user whether roaming has taken place just on screen.A kind of ERI of regulation in the TIA/EIA58b agreement (Enhanced Roaming Indicator strengthens the roaming designator) has stipulated that wherein numbering 3-63 is the ERI value of standard, and 64-127 is off-gauge ERI value, allows self-defined expansion.
For the processing of non-standard ERI, all can provide an ERI File (ERI file) usually at present, be pre-stored in the portable terminal internal memory, the corresponding ERI value of each clauses and subclauses among the ERI File by operator or portable terminal manufacturer.ERI File content comprises bell sound ID, prompt strings, Custom Icons.When portable terminal obtains the ERI value of current network correspondence, can remove to inquire about ERI File, find out corresponding bell sound ID, prompt strings and Custom Icons by the ERI value.Portable terminal not only can be pointed out the user by icon when roaming like this, can also play corresponding bell sound, shows corresponding character string etc., increases the user experience impression.
There is more problem in existing processing method for non-standard ERI, mainly comprises:
At first, to increase respective handling on the code to 64-127;
Secondly, the ERI File form that provides for operator and mobile-phone manufacturers needs the wholesale revision code not simultaneously, and is cumbersome;
At last, ERI File is kept in the portable terminal, and during its content changing, code is also wanted corresponding change, revises code and has not only postponed the time of launch, has brought risk also for the stability of product.
Summary of the invention
In view of above-mentioned analysis, the present invention aims to provide a kind of display packing and device of mobile terminal roaming designator, existing modification code trouble and influence problem such as product stability when handling for non-standard ERI in order to solve in the prior art.
Purpose of the present invention mainly is achieved through the following technical solutions:

Steps A: when start-up logging of mobile terminal to a new system or carried out system when switching, the system banner and the network identity that comprise in the local information that the UIM card is sent according to portable terminal, the inquiry optimum roaming list obtains the ERI value;
Step B: obtain corresponding roam prompting information according to the ERI value inquiry ERI file that inquires.
Further, the step that in advance the ERI file is kept in the UIM card specifically comprises:
Downloading the ERI file by aerial download technology is preset to the ERI file in the UIM card in the UIM card or directly.
Further, described steps A specifically comprises:
When start-up logging of mobile terminal to a new system or carried out system when switching, the UIM card requires portable terminal to issue local information with active command forms;
When portable terminal sent local information to the UIM card, the UIM card extracted system banner and network identity from local information, and obtained the ERI value according to system banner and network identity inquiry optimum roaming list.
Further, described step B specifically comprises:
Judge the validity of ERI value,, obtain corresponding roam prompting information according to ERI value inquiry ERI file, otherwise finish this handling process if effectively.
Further, also comprise:
UIM card triggering mobile terminals is pointed out the user according to the form of roam prompting information specifies.
Further, described roam prompting information comprises one or more in the following information:
Roam prompting bell sound ID, roam prompting character string and roam prompting icon.
Further, UIM card triggering mobile terminals points out user's step specifically to comprise with the form of roam prompting information specifies:
For roam prompting bell sound ID, the UIM card sends the proactive command of broadcast tone to portable terminal, requires the corresponding roam prompting bell of mobile terminal playing sound;
For roam prompting character string and/or roam prompting icon, the UIM card sends the proactive command of videotex to portable terminal, requires portable terminal to show corresponding roam prompting character string and/or roam prompting icon.
Further, also comprise:
When the ERI file upgraded, the ERI file after will upgrading by aerial download technology downloads in the UIM card to be preserved.
The present invention also provides a kind of mobile terminal roaming designator device shown, is arranged in the subscriber identification module UIM card, comprising:
Memory module is used for preserving in advance strengthening and roams designator ERI file;
Enquiry module, be used for when start-up logging of mobile terminal to a new system or carried out system when switching, the system banner and the network identity that comprise in the local information of sending according to portable terminal, the inquiry optimum roaming list obtains the ERI value, obtains corresponding roam prompting information according to ERI value inquiry ERI file then.
Further, also comprise:
Notification module is used for triggering mobile terminals and points out the user according to the form of roam prompting information specifies.
Beneficial effect of the present invention is as follows:
Be placed on the UIM card by the active order of employing UIM and with ERI File and corresponding judgment program, avoided revising the trouble of code, and can not bring any influence the stability of portable terminal product.
Other features and advantages of the present invention will be set forth in the following description, and becoming apparent from specification of part perhaps understood by implementing the present invention.Purpose of the present invention and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.
