Embodiment Construction

[0018] Since the third generation mobile communication cooperation project (3GPP: The 3 rd Generation Partnership Project), terminal capabilities are identified by version numbers released in different periods, so judging the terminal capability of a mobile terminal can be judged by looking at the version numbers in different periods corresponding to the binary code. Based on the 3GPP regulations, the present invention uses the core network equipment to judge the terminal capability of the user terminal, and selectively distributes the EPLMN list, avoiding the terminal error or even the inability to log in due to the failure of the user terminal to receive the EPLMN list network problem.

[0019] The present invention is applicable to networks of various standards, and each standard network has a corresponding wireless access network and a core network, and the wireless access network can be divided into a wireless access network of a GSM network, a wireless access network of...

Abstract

Present invention relates to a method for enhancing equal public land mobile network ( EPLMN ) functional. It includes 1, wireless subsystem receiving mobile terminal originated request, and transmitting core network equipment, 2, equipment extracting terminal capability message, and judging whether mobile terminal is R99and afterwards version, if it is then executing 4, otherwise executing 3, 3, core network equipment transmitting confirmed message to mobile terminal, then executing 6, 4, core network equipment adding EPLMN list to confirmed message and transmitting acknowledge information to mobile terminal, 5, mobile terminal storing EPLMN list, 6, mobile terminal access network operation. Said invention executes terminal capability checking before EPLMN list, to avoid problem resulting from user terminal no EPLMN function but received EPLMN list.

Description

technical field [0001] The present invention relates to a method for enhancing the function of Equivlent Public Land Mobile Network (EPLMN for short), especially a method for enhancing the function of EPLMN by issuing an EPLMN list through the terminal capability reported by a user terminal in the field of mobile communication. Background technique [0002] With the advent of 3G-based wireless technology, the types of services that wireless communication users can choose continue to increase. Correspondingly, mobile operators can simultaneously have multiple 2G and 3G networks to provide services. For example, for a certain mobile operator, when he owns a 3G network and a 2G network at the same time, he needs to apply for two corresponding network numbers respectively. During the use of the wireless service users of the operator, the users of the 3G network will automatically migrate to the 2G network. Obtain the International Mobile Subscriber Identity (IMSI) from the Uni...
