Device and method for controlling international visit user to log into preferred operator network

Abstract

The invention discloses a device which controls internationally visiting users to preferentially register on an operator network. The device is located between an internationally signaling transfer point and an import and export bureau of roaming country. The invention comprises a data storage module, a front end processor for processing signals and an operation maintenance platform; wherein, theoperation maintenance platform is applied to allocating number of a Visitor Location Register (VLR) and corresponding preferential relation of the VLR; the front end processor for processing signal intercepts a request message for updating location, analyzes the number of the VLR and user information, judges if the VLR meets the preferential relationship and transmits the message for updating location to a Home Location Register (HLR) for registration; otherwise, the user is refused to carry out registration through the VLR. The device can ensure that a terminal user can be registered on a preferential network according to predetermined operator preferential relationship when the terminal user visits other countries from homeland.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a device for controlling an international visiting user (ie, a user roaming out of the home country to other countries) to register with a preferred operator network (ie, a roaming country operator that has signed a preferred agreement with the operator in the country) and method. Background technique [0002] In a traditional mobile communication network, when an end user with international roaming rights roams out of the country, it will be registered in the MSC / VLR (MSC: Mobile Switching Centre, visiting mobile switching center; VLR: Visitor Location Register) of the mobile communication network in the roaming country. , Visiting Location Register) to register, and send a location update request message to the HLR (HLR: Home Location Register, Home Location Register) of the user's home operator to request location registration. After the HLR receives the location up...

Problems solved by technology

[0004] Although many mobile terminals currently allow users to manually select which operator network to register with, it is unrealistic for every roaming user to register with the corresponding network according to the agreement between operators, so an effective method must be adopted. The control method automatically controls the network registered by the end user when roaming abroad, so as to ensure the priority setting of the preferred network to the maximum extent

[0005] Currently, there is no solution
