Abstract

The invention relates to a multimode terminal which is provided with a disable EHPLMNs list used for recording a disable EHPLMN network number and a corresponding disable EHPLMN access technology as well as an unregistered EHPLMN access technology keeping terminal support. With the communication method of the multimode terminal, whether a selected PLMN (Public Land Mobile Network) is the disable EHPLMN or not can be judged and an unallowed PLMN can be placed in the disable EHPLMNs list, thereby effectively preventing the terminal from frequently updating position or route on the unregistered EHPLMN, being capable of avoiding that a user can not carry out communication service normally because of being in a process of selecting networks for a long time without influencing a user to update a position or route on a registered access technology under the PLMN network number.

Description

【Technical field】

[0001] The present invention relates to a multi-mode terminal and a communication method thereof, and more specifically, relates to a multi-mode terminal and a communication method thereof for effectively processing disabled EHPLMNs. 【Background technique】

[0002] 3GPP (3rd Generation Partnership Project) is a new standard for transmitting multimedia content through high-speed wireless networks. It is specially designed for mobile devices and can provide high-quality pictures and sound at low data rates. Since an operator has multiple MNC (Mobile Network Number) numbers, 3GPP proposed in its R7 series of specifications a technical mechanism for terminals to map HPLMN (home network) multiple times (that is, EHPLMN access technology), and also stipulates that EHPLMN cannot Put it in the list of banned PLMNs.

[0003] PLMN (Public Land-Mobile Network, Public Land-Mobile Network) is a mobile network equivalent to the Public Switched Telephone Network (PSTN). ...
