Abstract
Embodiments of the present invention include a method for enhanced indication of network support of SRVCC and/or Voice-over-IMS for an User Equipment UE in an Evolved Packet System EPS network, said method comprising at least one step based on taking into account support of SRVCC and/or Voice-over-IMS by Radio Access Network RAN nodes and/or by Radio Access Technologies RATs available for SRVCC for said UE in said EPS network.
Claims19
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- signal to a core network entity serving an user equipment served by said apparatus in a mobile communication network, information as to voice-over-IMS support by radio access network nodes in said mobile communication network, wherein the information as to voice-over-IMS support by radio access network nodes comprises radio access network-level-support information, said signalling allowing a voice-over-IMS indication indicating voice-over-IMS supported or voice-over-IMS not supported sent by said core network entity to said user equipment to take said radio access network-level-support information into account.
2 more elements
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- receive from a radio access network node serving a user equipment served by said apparatus in a mobile communication network, information as to voice-over-IMS support by radio access network nodes in said mobile communication network, wherein the information as to voice-over-IMS support by radio access network nodes comprises radio access network-level-support information, and
- send to said user equipment a voice-over-IMS support indication, indicating voice-over-IMS supported or voice-over-IMS not supported, taking into account said radio access network-level support information.
3 more elements
A method comprising:
- signaling to a core network entity serving an user equipment served by a radio access network node in a mobile communication network, information as to voice-over-IMS support by radio access network nodes in said mobile communication network, wherein the information as to voice-over-IMS support by radio access network nodes comprises radio access network-level-support information, said signalling allowing a voice-over-IMS indication indicating voice-over-IMS supported or voice-over-IMS not supported sent by said core network entity to said user equipment to take said radio access network-level-support information into account.
A method comprising:
- receiving from a radio access network node serving a user equipment served by a core network entity in a mobile communication network, information as to voice-over-IMS support by radio access network nodes in said mobile communication network, wherein the information as to voice-over-IMS support by radio access network nodes comprises radio access network-level-support information, and
- sending to said user equipment a voice-over-IMS support indication, indicating voice-over-IMS supported or voice-over-IMS not supported, taking into account said radio access network-level support information.
