Network sharing and reverse single radio voice call continuity
First Claim
1. A method, comprising:
- requesting, handover of a user equipment from a packet switched source network to a circuit switched target network, wherein the handover request comprises a single radio voice call continuity request from the packet switched source network to the circuit switched target network; and
providing with the handover request, being handled by the circuit switched target network, a network identification of the packet switched source network,wherein the network identification comprises an identification of a public land mobile network identifying the packet switched source network, andwherein the identification of the packet switched source network is used by the circuit switched target network for selecting another target network.

Abstract
Certain networks can operate using circuit switched infrastructure, while other networks may operate using infrastructure for the long term evolution (LTE) of the third generation partnership project (3GPP). Devices can operate across the boundaries of these networks. Thus, such devices as well as the networks may benefit from network sharing in reverse single radio voice call continuity. For example, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include providing a network identification corresponding to the source network while requesting the handover. Alternatively, or in addition, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include determining the target network based on a network identification received previously.

3. An apparatus, comprising:
-
at least one processor; and at least one memory comprising computer program codes, wherein the computer program codes which, when executed by the at least one processor, cause the apparatus at least to request handover of a user equipment from a packet switched source network to a circuit switched target network, wherein the handover request comprises a single radio voice call continuity request from the packet switched source network to the circuit switched target network; and provide with the handover request, being handled by the circuit switched target network, a network identification of the packet switched source network, wherein the network identification comprises an identification of a public land mobile network identifying the packet switched source network, and wherein the identification of the packet switched source network is used by the circuit switched target network for selecting another target network. - View Dependent Claims (4, 5)
