Embodiment Construction

[0023] figure 1 An exemplary embodiment of the system according to the invention is shown. exist figure 1 In , three networks 400, 500 and 600 are shown for explanatory purposes. OID #1 is assigned as the operator identifier of the operator of network 400 , OID #2 is assigned as the operator identifier of the operator of network 500 , and OID #3 is assigned as the operator identifier of the operator of network 600 . The operator identifier may be a combination of a Mobile Country Code (MCC) and a Mobile Network Code (MNC).

[0024] exist figure 1 , a network 400 includes a Radio Access Network (RAN) 2 , a network device 3 and a registration server 4 . Network device 3 is connected to RAN 2 and registration server 4 . Furthermore, network device 3 is connected to registration servers 5 and 6 of networks 500 and 600, respectively. Networks 500 and 600 also include RAN and network equipment; however, for brevity, not in figure 1 shown in .

Abstract

The present invention relates to automatic provisioning of wireless devices. The wireless device (1) has a device identifier and a first private key generated from the device identifier. The registration server (5) has an operator identifier and a second private key generated from the operator identifier. The wireless device (1) sends a device identifier to a registration server (5), and the registration server (5) sends a subscriber identifier to the wireless device (1). The wireless device (1) generates a shared key based on the operator identifier and the first private key, and the registration server (5) generates a shared key based on the device identifier and the second private key.

Description

technical field [0001] The present invention relates to automatic provisioning of wireless devices. Background technique [0002] In current wireless networks, wireless devices need to perform an attach procedure to initiate communication over the network. Image 6 An overview of the attach procedure according to "General Packet Radio Service (GRPS) enhancement for Evolved Universal Terrestrial Radio AccessNetwork (E-UTRAN) access (Release 9)" (3GPP TS 23.401 V9.3.0) is shown. For simplicity, the registration server is represented as a single device; however, it could also be multiple devices. [0003] In step S21, the wireless device sends an attach request signal to a network device such as a Serving GPRS Support Node (SGSN), the attach request signal including a subscriber identifier called an International Mobile Subscriber Identifier (IMSI) assigned to the wireless device . In step S22, the network device sends an authentication data request signal to the registration...
