Embodiment Construction

[0030] The invention provides a control system and method for a terminal to use a network. When a terminal attempts to access the network, the network can automatically detect whether the terminal is an unauthorized terminal, and if it is an unauthorized terminal, it can be prevented from using the network.

[0031] Such as figure 2 Shown is a schematic diagram of the first embodiment of the present invention. Wherein, a network of an operator is only schematically drawn. The terminal involved in the present invention refers to a terminal that has a unique terminal equipment identifier and can obtain a network identifier assigned by an operator, such as a terminal with a SIM (Subscriber Identity Module) card, a USIM (Universal Subscriber Identity Module) card and an ISIM (IMS Mobile phones, PDAs, notebook computers and other terminal equipment such as Subscriber Identity Module) cards, and even fixed terminals (such as IMS terminals in next-generation networks). The network...

Abstract

The system at least comprises: a network switch center that can receive the logon from the terminals and a terminal device identification center intercommunicating with said network switch center. The authentication information of network subscription user is pre-stored in the terminal device identification center; the network switch center receives the logon information from terminal device, and sends the request message for requesting the authentication information about the user to the terminal device identification center, and according to the returned message decides if its access is permitted.

Description

technical field [0001] The present invention relates to the security field in mobile communication, in particular, to a control system and a control method for a terminal using a network. Background technique [0002] In mobile communication, the device identification number is used to manage the mobile terminal. For example, in a public land mobile network (Public land mobile network, PLMN), there is a functional unit called an equipment identity register (Equipment Identity Register, EIR), which is mainly responsible for managing equipment identities of mobile terminals in the network. In the GSM network, the device identification refers to the International Mobile Equipment Identity (IMEI), and in the CDMA network, the device identification refers to the Electronic Serial Number (ESN). The following uses the GSM network as an example to describe. [0003] The IMEI code in the GSM network is the unique identifier of a mobile terminal and cannot be changed. Its main purpo...
