Secure communication network user mobility apparatus and methods are disclosed. A mobile user that is locally connected to a first communication network in which a service is provided, but is associated with an independently controlled second secure communication network, may be authenticated for access to the service by the second communication network. This allows seamless user mobility between networks in a partner extranet or other collection of trusted networks based on existing inter-network user mobility relationships. Access control, monitoring, and reporting, for example, and possibly other functions, may also be provided.
