Abstract

A method of mobility management in a cellular system includes determining from a first received indication that at least one communication device intends to receive a multimedia broadcast multicast service or is receiving a multimedia broadcast multicast service. The information is sent to the at least one communication device relating to at least one multimedia broadcast multicast service capable cell. The method further includes receiving from the at least one communication device a report including measurement information of the at least one multimedia broadcast multicast service capable cell. The method finally includes initiating selecting at least one cell on at least one carrier for the at least one communication device, the at least one carrier including one or more cells capable of providing a multimedia broadcast multicast service.

Claims38

Dependent claims

An apparatus comprising:

at least one processor;
and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
for mobility management in a cellular system perform:
determining, with a network node, from a first indication received from at least one mobile communication device that the at least one mobile communication device intends to receive a multimedia broadcast multicast service or is receiving a multimedia broadcast multicast service;
based on the determining sending, with the network node, to the at least one mobile communication device first information relating to cells, wherein the first information excludes information relating to cells which do not support multimedia broadcast multicast services;
receiving, with the network node, from the at least one mobile communication device a second indication that the at least one mobile communication device no longer intends to receive the multimedia broadcast multicast service or is no longer receiving the multimedia broadcast multicast service;
based on the second indication, sending, with the network node, to the at least one mobile communication device second information relating to cells, wherein the second information no longer excludes information related to cells which do not support multimedia broadcast multicast services;
and
in response to the second information, receiving, with the network node, from the at least one mobile communication device a report comprising measurement information based on the second information.

An apparatus comprising:

at least one processor;
and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
send to a network node in a cellular system a first indication that the apparatus intends to receive a multimedia broadcast multicast service or is receiving a multimedia broadcast multicast service, wherein the apparatus comprises a mobile communication device;
in response to the first indication, receive from the network node in the cellular system first information relating to cells, wherein the first information excludes information related to cells which do not support multimedia broadcast multicast services;
send to the network node in the cellular system a second indication that the apparatus no longer intends to receive the multimedia broadcast multicast service or is no longer receiving the multimedia broadcast multicast service;
based on the second indication, receive from the network node second information relating to cells, wherein the second information no longer excludes information related to cells which do not support multimedia broadcast multicast services;
and
send to the network node a report comprising cell measurements based on the second information.

A method, comprising:

determining, by a network node, from a first indication received from at least one mobile communication device that the at least one mobile communication device intends to receive a multimedia broadcast multicast service or is receiving a multimedia broadcast multicast service;
based on the determining, sending, by the network node, to the at least one mobile communication device first information relating to cells, wherein the first information excludes information relating to cells which do not support multimedia broadcast multicast services;
receiving, by the network node, from the at least one mobile communication device a second indication that the at least one mobile communication device no longer intends to receive the multimedia broadcast multicast service or is no longer receiving the multimedia broadcast multicast service;
based on the second indication, sending, by the network node, to the at least one mobile communication device second information relating to cells, wherein the second information no longer excludes information relating to cells which do not support multimedia broadcast multicast services;
and
in response to the second information, receiving, by the network node, from the at least one mobile communication device a report comprising measurement information based on the second information.
