Embodiment Construction
[0044] The main problem of the current equipment identification legality inspection scheme is: under the background that the global EIR cooperation has not been well developed, when the user is located in the visited network, the visited network needs to check the legality of the equipment identification in the EIR of the home network , the resource management control node of the visited network needs to transmit the device identifier of the terminal used by the user to the gateway node and / or user subscription data storage node of the home network, and query the EIR of the home network through the gateway node or user subscription data storage node of the home network. A further device identification check is performed. This solution needs multiple network elements in the visited network and the home network to forward the device identification check request message to realize the legality check of the device identification. It can be seen that the existing device identificati...

The invention discloses a method and a device for checking the validity of device identification to reduce the network resource consumed in the checking process and shortening the time delay in the checking process. The method comprises the following procedures: resource management controlling nodes of a visiting network obtains the EIR address of a home network according to the relevant information about users; the resource management controlling nodes of a visiting network sends a piece of device identification checking request information to the obtained EIR address and the information carries along with the device identification of the users; the resource management controlling nodes of a visiting network receives the checking result to the validity of device identification from the EIR. The resource management controlling unit is arranged in the visiting network and comprises an obtaining cell used for obtaining the EIR address of the home network according to the relevant information about users, a sending cell used for sending device identification checking request information which carries along with the device identification of the user to the EIR address, and a receivingcell used for receiving the returned checking result to the validity of device identification.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and a device for checking the legitimacy of equipment identification. Background technique [0002] The current architecture of mobile packet domain networks, see figure 1 As shown, GGSN (Gateway GPRSSupporting Node, gateway GPRS support node) is the gateway between the mobile communication network and the IP network, and is responsible for assigning an IP address to the UE (User Equipment, user terminal), so that the UE can access the IP network. The SGSN (Serving GPRS Support Node, Serving GPRS Support Node) is responsible for resource management and control, selects a suitable GGSN for the user, and provides a channel for communication between the UE and the GGSN. HLR / HSS (Home Location Register, Home Subscription Storage, Home Subscription Storage) is responsible for storing user subscription data. After 3GPP R7, the user plane data is allowed to be directly transmitted b...
