Abstract

The embodiment of the invention discloses an establishment method and an establishment device of communication links. The method comprises the steps of allowing a mobile terminal to establish the first communication link with a first wireless communication network side in a roaming place by utilizing a built-in SIM (Subscriber Identity Module) card and to obtain a mobile country code or a location area code of a first wireless communication network, allowing the mobile terminal to obtain a USIM (Universal Subscriber Identity Module) card corresponding to the mobile country code or the location area code from a cloud management center, and allowing the mobile terminal to establish the second communication link with a second wireless communication network side by utilizing the USIM card and to release the first communication link. In the method, the mobile terminal utilizes the built-in SIM card to obtain the USIM card from the cloud management center and then utilizes the USIM card to establish connection with equipment on the wireless communication network side in the roaming place, so that high roaming charges of a roaming subscriber caused by using roaming data flow in the roaming place are saved, the usability of the mobile terminal is improved, and the operating cost is lowered.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for establishing a communication link. Background technique [0002] With the rapid development of mobile communications, dual-card dual-standby mobile terminals (such as mobile phones) are gradually becoming popular. In a dual-card dual-standby mobile terminal, two card slots for user identification are provided, two cards (such as a customer identification module (SIM, Subscriber Identity Module) card and a global subscriber identification module (USIM, Universal Subscriber Identity) Module) cards can be in the standby state at the same time, and the user can operate two cards with one mobile terminal. [0003] In the existing technology, if you use a SIM card or USIM card to surf the Internet in a roaming area, a large amount of roaming fees will be generated; if you replace it with a local SIM card or a local USIM card in a roaming area, the...
