Best effort call routing preference setting
First Claim
1. A method of providing call control within a mobile network with respect to a subscriber associated to one or a plurality of user equipments (UEs), the mobile network comprising a packet switched (PS) access domain, a circuit switched (CS) access domain, and an application server (AS) responsible for an access domain selection, the application server performing the following steps:
- receiving, from a UE, a routing request to establish a call to the subscriber, the request including an indication identifying a preferred access domain for routing the call;
receiving, from a Home Subscriber Server (HSS), access network capability information associated with the subscriber;
selecting an access domain for routing the call, where the access domain selection further comprises selecting the PS access domain responsive to determining that the access network capability information indicates that IP Multimedia Subsystem (IMS) Voice over PS is supported or selecting the PS access domain responsive to determining that the access network capability information indicates that IMS Voice over PS is not supported but that the received indication identifies the PS access domain as the preferred access domain; and
causing the call to be routed via the selected access domain.

12. An application server, in a network including a packet switched (PS) access domain and a circuit switched (CS) access domain, comprising:
-
a receiver adapted to; receive, from a user equipment (UE), a routing request to establish a call to a subscriber, the request including an indication identifying a preferred access domain for routing the call, and receive, from a Home Subscriber Server (HSS), access network capability information associated with the subscriber; and a processor adapted to; select an access domain for routing the call, where the access domain selection further comprises selecting the PS access domain responsive to determining that the access network capability information indicates that IMS Voice over PS is supported or selecting the PS access domain responsive to determining that the access network capability information indicates that IMS Voice over PS is not supported but that the received indication identifies the PS access domain as the preferred access domain; and cause the call to be routed via the selected access domain.
