Access method, user equipment and server

Abstract

The embodiment of the invention provides an access method. The access method comprises the following steps of: establishing a first link between user equipment and a first mobile communication network according to a first user identification code; requesting a server for distributing a second user identification code to the user equipment through the first link, wherein the second user identification code is a user identification code corresponding to one SIM card in the server; and furthermore, the second user identification code is a local user identification code at the position, where the user equipment is currently; obtaining the second user identification code distributed by the server through the first link; and establishing a second link between the user equipment and a second mobile communication network in the current position according to the second user identification code. By means of the embodiment of the invention, the roaming charge can be reduced; and the communication quality can be improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to an access method, user equipment and server. Background technique [0002] When users roam abroad, all communication services are provided by overseas operators, resulting in high roaming charges for international roaming. With the increasingly frequent international exchanges, high roaming charges have become an urgent problem to be solved in international exchanges. [0003] In the prior art, when a user is abroad, he usually directly purchases a Subscriber Identity Module (Subscriber Identity Module, hereinafter referred to as a SIM card) from a foreign local operator, and replaces the SIM card in the mobile phone with a local SIM card, thereby directly using the local card for communication. , avoiding expensive international roaming charges. However, if the user replaces the SIM card on the User Equipment (hereinafter referred to as U...

Problems solved by technology

However, if the user replaces the SIM card on the User Equipment (hereinafter referred to as UE) with a local SIM card, the personal data stored on the original SIM card cannot be easily transferred to the newly purchased local SIM card, and once the user leaves The region that supports the purchased SIM card will inevitably involve the need to purchase a new SIM card for the newly arrived region, which undoubtedly increases the cost and is inconvenient to use
