Service control network and its control method

A control method of a service control network comprising an authentication server device for performing user authentication, an edge device for performing Layer-3 service processing for a mobile terminal managed by said edge device, and a service control device for performing Layer-7 service control for the mobile terminal, wherein:

• the mobile terminal transmits an authentication request message to said edge device;
• said edge device transmits said authentication request message to said service control device;
• said service control device transmits the authentication request message concerned to said authentication server device;
• said authentication server device transmits an authentication response message together with a dependent Layer-3 profile and an independent Layer-3 profile related to a Layer-7 profile concerned at the success of the authentication of the mobile terminal;
• said service control device caches a Layer-7 profile of said authentication response message and an independent Layer-3 profile of another edge device which will be a communication partner of said service control device;
• said edge device caches an independent Layer-3 profile and/or a dependent Layer-3 profile of said edge device of said authentication response message;
• said edge device performs Layer-3 service processing for packets which have been received from the mobile terminal and match the independent Layer-3 profile, and transfers packets, which have been received from the mobile terminal and match the dependent Layer-3 profile, to said service control device;
• and
• said service control device transfers the independent Layer-3 profile to said another edge device, and controls the implementation of a Layer-7 service concerned for packets which have been received from said edge device and match the Layer-7 profile.
