International Classification:

H04Q 7/20

US Classification:

455436, 455445, 4554565, 370331

Abstract:

In a telecommunications network in which a mobile handset is capable of communicating in both an IP domain and a non-IP domain, the handoff of an existing communications session between the mobile handset and a fixed user is facilitated by a handoff controller implemented in a service control point. The handoff controller implements different handoff methods depending on the status of the fixed user and the transition of the mobile user. Additionally 802. 21 Media Independent Handover Function in conjunction with SIP is used to facilitate handover between IP and Non-IP points in the system.

International Classification:

H04Q 7/20

US Classification:

455436000

Abstract:

A network-based Adaptive Seamless Mobility Controller provides a view not only of the capabilities of the specific device in use by the user but also the capabilities of the access network serving each user involved in the session. When the user equipment identifies the opportunity to enhance the communication through adaption of the session to include, for example, a video connection in addition to a voice connection, by utilizing a different access network and corresponding device, the network-based Adaptive Seamless Mobility Controller determines the end-to-end capabilities required for the session and coordinates the adaptation of the session characteristics in addition to providing seamless handover across domains.

International Classification:

H04L 12/14
H04L 12/26

Abstract:

In a method carried out in a telecommunication network, a policy decision function provides an instruction to a policy enforcement function and/or a traffic detection function. Within the instruction, some service instances of a service are identified by the order according to which the service instances are started. The instruction also indicates: (i) a service instance level reporting rule according to which the policy enforcement function and/or traffic detection function should report, or should not report, information to the policy decision function after occurrence of an event relating to any one of the identified service instances; and/or (ii) a service instance level enforcement rule that the policy enforcement function and/or traffic detection function should enforce on a received packet relating to any one of the identified service instances. The invention also relates to network nodes and computer programs.
