Problems solved by technology

[0016] (1) Operators cannot define the different usage priorities of FDD, TDD LCR and TDD HCR of PLMN according to the needs of network construction or roaming agreement and other network operations;
[0017] (2) Mobile users cannot define different usage priorities of non-HPLMN FDD, TDD LCR and TDD HCR according to their own preferences for tariffs or network service experience;
[0018] (3) During use, the three-mode terminal will search for all three wireless access technologies, resulting in prolonged PLMN search time for the terminal;
[0020] (5) The paging success rate index of the wireless system to the terminal is reduced (the terminal cannot monitor the paging message during the PLMN search process), and it will affect the standby time of the terminal
[0028] In this scheme, the search for the FDD frequency band must be fruitless, so that there is an inevitable unnecessary time-consuming and power-consuming process in this scheme.

Embodiment Construction

[0064] The core of the present invention is to set a specific indication of each wireless access technology in the identification information corresponding to each PLMN in the PLMN selection list applied by the wireless terminal, so that when the wireless terminal selects the wireless access technology used by the access network , the corresponding wireless access technology can be selected accurately and quickly, and the efficiency of selecting the PLMN for the wireless terminal is improved.

[0065] In the specific implementation process of the present invention, the indication information of each radio access technology that a certain PLMN can choose to apply can be set at any position in the PLMN entry.

[0066] In practical applications, considering that according to the current stipulations of 3GPP specification TS 31.102, the first byte in the PLMN entry is used to represent the wireless access indication information, therefore, the present invention will modify the corr...

Abstract

The method comprises: in the ID information corresponding to each PLMN in the PLMN selection list, setting the indication information used for indicating each radio access approach in order to make a radio terminal capable of fast and accurately selecting the corresponding radio access approach in term of the indication message so as to improve the efficiency of selecting radio terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method for realizing the selection and application of wireless access technology. Background technique [0002] According to 3GPP 23.122, in the automatic PLMN (Public Land Mobile Network) selection mode, when the terminal is turned on and recovers from no coverage area, it should follow the RPLMN (registered PLMN), USIM (3G Subscriber Identity Module) card HPLMN ( PLMNs are searched for in the order of the home PLMN) list, the UPLMN (user PLMN) list, and the OPLMN (operator PLMN) list. When the terminal is in the roaming state, it needs to periodically search for a PLMN with a higher priority than the current VPLMN (visiting PLMN) in the HPLMN list, UPLMN list, and OPLMN list. When the terminal is turned on, the PLMN list is read from the USIM card through the Cu interface, and the list items include the PLMN number and the RAT (Radio Access Technology...
