An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- signal said radio access network-level support information to said core network entity in a dedicated message.
An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- determine said radio access network-level support information.
An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- determine said radio access network-level-support information using at least one of information as to radio capabilities of said user equipment, and radio access network configuration information.
An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- receive information as to radio capabilities of said user equipment signalled to said apparatus by said core network entity.
An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- receive information as to radio capabilities of said user equipment signalled to said apparatus by said core network entity during at least one of an attach procedure and a mobility management procedure for said user equipment.
An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- receive information as to radio capabilities of said user equipment signalled to said apparatus by said core network entity in a dedicated message.
An apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- during a procedure triggered by said core network entity, first receive user equipment radio capabilities in a downlink signaling message, and then respond with said radio access network-level-support information sent to said core network entity.
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.
An apparatus according to claim 10, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- receive said radio access network-level-support information during one of an attach procedure and a mobility management procedure for said user equipment.
An apparatus according to claim 10, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- receive said radio access network-level support information in a dedicated message.
An apparatus according to claim 10, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- signal information as to radio capabilities of said user equipment to said serving radio access network node.
An apparatus according to claim 10, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- signal said information as to radio capabilities of said user equipment to said radio access network node during one of an attach procedure and a mobility management procedure for said user equipment.
An apparatus according to claim 10, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- signal said information as to radio capabilities of said user equipment to said serving radio access network node in a dedicated message.
An apparatus according to claim 10, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- trigger a procedure whereby user equipment radio capabilities are first sent to the serving radio access network node in a downlink signaling message, and then the apparatus receives said radio access network-level-support information from said serving radio access network node.
An apparatus according to claim 10, wherein the radio access network-level support information takes into account information as to radio capabilities of said user equipment and/or radio access network configuration information.
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.
