Abstract
There is provided an apparatus comprising means for performing: determining a presence of at least one user equipment that is participating in a multicast session while in an inactive state; determining an area where handling of the multicast session for the at least one user equipment in inactive state is required; determining one or more nodes handling cells within at least a part of the determined area for handling the multicast session; in response to the determining a presence of at least one user equipment in inactive state, sending to each determined node a request to handle the multicast session for the at least one user equipment in inactive state.
Claims10
A radio access network node (RAN) for a communication network, the RAN node comprising:
- at least one processor;
- and
- at least one memory storing instructions which, when executed by the at least one processor, cause the RAN node to at least perform:
- detecting that at least one inactive user equipment that is served by the RAN node is participating in a multicast session;
- determining a distribution area of the multicast session, wherein the distribution area is an area where handling of the multicast session for the at least one inactive user equipment is required, wherein the determining the distribution area comprises:
- combining information about radio access network notification areas of respective inactive user equipment of the at least one inactive user equipment to generate information about a combined area;
- comparing the information about the combined area with information about a service area for the multicast session to determine a region of overlap between the combined area and the service area;
- and
- setting the distribution area to the region of overlap;
- determining one or more neighbour RAN nodes of the RAN node handling cells within at least a part of the distribution area of the multicast session;
- and
- sending to each respective neighbour RAN node of the one or more neighbour RAN nodes, a respective request to perform handling of the multicast session for the at least one inactive user equipment, each respective request comprising information about the distribution area of the multicast session.
A method comprising:
- detecting, by a radio access network (RAN) node, that at least inactive one user equipment that is served by the RAN node is participating in a multicast session;
- determining, by the RAN node, a distribution area of the multicast session, wherein the distribution area is an area where handling of the multicast session for the at least one inactive user equipment is required, wherein the determining the distribution area comprises:
- combining information about radio access network notification areas of respective user equipment of the at least one inactive user equipment to generate information about a combined area;
- comparing the information about the combined area with information about a service area for the multicast session to determine a region of overlap between the combined area and the service area;
- and
- setting the distribution area to the region of overlap;
- determining, by the RAN node, one or more neighbour RAN nodes of the RAN node that control cells within at least a part of the distribution area of the multicast session;
- sending to each respective neighbour RAN node of the one or more neighbour RAN nodes, a respective request to handle the multicast session for the at least one inactive user equipment, each respective request comprising information about the distribution area of the multicast session.
