International signaling transfer point and working method

Abstract

The invention discloses an international signaling switching point device and a working method. The international signaling switching point device comprises a data storage module, a signaling processing front end computer and an operation and maintenance console; wherein, the number of a visitor locator register and the preferential relationship to which the VLR corresponds are configured in the data storage module by utilizing the operation and maintenance console and the signaling processing front end computer intercepts a request message for location update and analyzes the VLR number and the user information from the request information, and carries out the unvarnished transmission of the update information to the home location register HLR for registration when deciding that the VLR satisfies the preference relationship, otherwise, the signaling front end computer denies the registration through the VLR of the users. The international signaling switching point device and the working method of the invention 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, and in particular to an international signaling transfer point device and its work on the home country side of a mobile communication network that controls international visiting users (that is, users roaming from their own country to other countries) to register with the operator network of the roaming country 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 re...

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
