Method for accessing a second data communication network and corresponding device and system

摘要

The invention relates to a method for accessing a second data communication network 120. According to the invention, a first data communication network 100 includes a network detection entity 110. The method comprises the following steps. The network detection entity detects a device 14 under a radio coverage of the first data communication network. The network detection entity sends to a first remote server 112 information 26 and at least one identifier relating to a device. The first remote server is included within the first data communication network. The first remote server retrieves an identifier relating to an access point 114 that is associated with the information. The access point is included within a second data communication network. The first remote server sends to the device at least one first message 28 comprising the identifier relating to an access point. And the device sends to the access point a request 220 for launching an authentication procedure. The invention also pertains to corresponding device and system.
