Description

Method for setting short message coding range based on attribution language, positioning information and short message content

Technical Field

The invention relates to the field of short message language coding, in particular to a method for setting a short message coding range based on a home location language, positioning information and short message content.

Background

When the terminal roams to a foreign network, the terminal can send short messages to communicate with the foreign network by using foreign local language characters with high probability. At this time, when the user terminal communicates with the foreign user, the user terminal generally communicates with the foreign user through the foreign language and character short message. The prior art can only inquire a corresponding GSM7 default code alternative table and a GSM7 extended code alternative table according to the country code of a SIM card inserted by a user terminal. When there are multiple language codes in a country (the same MCC) (for example, india) and the languages corresponding to different bangs are different, the GSM7 extension code substitution table corresponding to the language cannot be accurately loaded and confirmed in time only by the MCC of the SIM card.

Disclosure of Invention

The invention provides a method for setting a short message coding range based on a home location language, positioning information and short message content, which solves the problem that a GSM7 extended code substitution table corresponding to a language is timely and accurately loaded and confirmed under the condition that a plurality of language codes exist in one country.

The technical problem to be solved by the invention is realized by the following technical scheme:

the invention provides a method for setting a short message coding range based on a home location language, positioning information and short message content, which is characterized by comprising the following steps: after the terminal roams to a foreign network, searching which country the roaming network belongs to through a currently registered Public Land Mobile Network (PLMN); confirming the specific operator of the user and the city or area matched with the operator through the registered MCC and MNC information, and confirming the city information; when the user terminal is located in a city or region of a country, it is determined which language code is used according to the language use habit of the region, and the corresponding GSM7 default code replacement table and GSM7 extended code replacement table combination are inquired and set in the terminal.

Preferably, when editing the short message, the GSM7 extended code substitution table of the country is traversed preferentially.

Preferably, when the user uses the terminal to communicate with the foreign user by short messages, the country code is determined by judging the home location of the foreign user number, the user selects between the country to which the roaming network belongs and the country of the foreign user, and then the corresponding combination of the GSM7 default code replacement table and the GSM7 extended code replacement table is inquired according to the country code and is set in the terminal.

Preferably, when the user uses the terminal to communicate with the foreign user short message, the user can judge which country character is according to the foreign language character contained in the short message, the user selects between the country to which the roaming network belongs and the country of the foreign user, and then the corresponding GSM7 default code replacement table and the GSM7 extended code replacement table are inquired according to the country code and set in the terminal.

The invention has the advantages that when a plurality of language codes exist in a country, the GSM7 extension code alternative list corresponding to the language can be timely and accurately loaded and confirmed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 is a flow chart of querying through roaming information by the method for setting a short message encoding range based on a home language, positioning information and short message content according to the embodiment. When a user uses the terminal to roam to a foreign network, the terminal can inquire the current registered PLMN, the PLMN is composed of MCC and MNC, and the country in which the terminal roams can be confirmed according to the MCC. The specific operator of the subscriber can be identified by the registered MCC MNC information. Some operators in countries such as India only match with fixed cities, can confirm city information through the information of the operators, inquire the corresponding GSM7 default code replacement table and the GSM7 extended code replacement table combination to be arranged in a terminal, when editing short messages, preferentially traverse the GSM7 extended code replacement table of the country, reduce interface delay and performance reduction caused by excessive traverse of the GSM7 language code table, and also reduce the byte length of short message transmission. For example, the operator corresponding to indian andela bang is aiccel, the MCC MNC of the operator at indian andela bang is 405801, when the terminal takes the MCC MNC information, it can be confirmed that the operator is at andela bang, the common language corresponding to the bang is tylugu, and at this time, the GSM7 default code substitution table and the GSM7 extended code substitution table corresponding to tylugu are automatically loaded, so as to reduce the occupation of more channel resources by the user input characters in transmission. If not, the method must be converted into UCS2 coding, UCS2 codes a character occupies 2 bytes, and GSM 7bit Default Alphabet and GSM 7bit extension codes corresponding to Telugu language only occupy 7 bits.

When a user uses a terminal to exchange short messages with foreign users, the country code of the user is determined by judging the home location of the foreign user number, the user selects between the country to which the roaming network belongs and the country of the foreign user, then the corresponding combination of the GSM7 default code replacement table and the GSM7 extension code replacement table is inquired according to the country code and is arranged in the terminal, when the short messages are edited, the GSM7 extension code replacement table of the country is preferentially traversed, the interface delay and the performance reduction caused by too many traversed GSM7 language code tables are reduced, and the byte length sent by the short messages can be reduced. For example: when the user terminal carries out short message communication with the mobile phone number of the Turkish, the user terminal can take the number of the Turkish, and judge that the number prefix is at the beginning of 90, the user terminal can be considered to be in short message communication with the user of the Turkish, so that a GSM7 Default code replacement Table and a GSM7 extended code replacement Table of the Turkish can be loaded according to the country code of the Turkish, and a GSM 7bit Default letter Table can be replaced by a Turkish National Language Locking Shift Table, so that more channel resources occupied by the user input characters in transmission can be reduced.

When a user uses a terminal to exchange with a foreign user short message, the user judges which country character is according to foreign language characters contained in the short message, the user selects between the country to which the roaming network belongs and the country of the foreign user, then the corresponding GSM7 default code replacement table and the GSM7 extension code replacement table are inquired according to country codes and are arranged in the terminal, when the short message is edited, the GSM7 extension code replacement table of the country is preferentially traversed, and the problem that the GS replacement table is traversed due to the fact that the GS is traversed is reducedThe excessive M7 language coding tables cause interface jamming and performance degradation, and can also reduce the byte length of short message transmission. For example: when traversing the content of the short message, the short message is found to contain

When the letters of Turkish are used, the user can be determined to be exchanging with the short message of the Turkish user, so that the GSM7 Default code substitution Table and the GSM7 extended code substitution Table of the Turkish can be loaded according to the country code of the Turkish, and the GSM 7bit Default code Shift Table can be replaced by the Turkish National Language Locking Shift Table, so that more channel resources are occupied by the user input characters in transmission. If not, the method must be converted into UCS2 encoding, UCS2 encoding one character occupies 2 bytes, and one character of 'GSM 7bit Default alpha beta' and 'Turkish National Language Locking Shift Table' only occupies 7 bits.
