Abstract: Handling of related identities may be valuable in communication systems. More particularly, in areas such as long term evolution advanced (LTE-A) proximity services (ProSe), it may be useful to provide for handling of ProSe device to device (D2D) related identities at the radio access network (RAN) level. A method can include deriving an initial layer one identifier corresponding to a target user equipment or group. The method can also include determining whether the initial layer one identifier collides with another layer one identifier corresponding to a different target user equipment or group. The method can further include communicating with the target user equipment or group based on the determination of whether the initial layer one identifier collides with another layer one identifier in use.

Abstract: A method of transmission of excess data associated with a multicast service is scheduled on another radio communication resource. The multicast service may be MBMS or push-to-talk. The method includes determining, at the eNodeB base station, that an amount of data to be multicast during an upcoming scheduling period exceeds the associated multicast communication resource, and accordingly temporarily allocate additional resources on another multicast service communication resource, or else on resources dedicated to conventional services, or else on both kind of resources simultaneously. The base station transmits an indication to the UE(s) about the additional allocation(s) by using MCH scheduling information, such signaling comprising a logical channel identification, LCID, field.

Abstract: Various communication systems may benefit from network location reporting. For example, such reporting may be beneficial in the establishment of a multimedia broadcast/multicast service bearer for media traffic delivery from a group communication service application server or other similar device or system. A method can include reporting at least a first set of user equipment location information and at least a second set of user equipment location information from the user equipment to at least one network node for broadcast bearer management. The first set of user equipment location information can include a serving cell identity of the user equipment. The second set of user equipment location information can include at least one identity of at least one network service area for media broadcasting.

Abstract: Systems, methods, apparatuses, and computer program products for supporting local MBMS distribution are provided. One method includes receiving, by a broadcast multicast service center (BM-SC), an activate multimedia broadcast multicast service (MBMS) bearer request message to initiate an activate multimedia broadcast multicast service (MBMS) bearer request procedure. The activate MBMS bearer request message comprises at least one of information on local MBMS distribution received from a local MBMS entity (LME), or a destination area, or a destination area and an indication that preferred delivery is via local distribution. The method may further include determining whether local distribution path will be used based on at least one of information received in the activate MBMS bearer request message, or stored information about local MBMS entities.

Abstract: Various communication systems may benefit from a dynamic streaming service. For example, certain streaming services may benefit from an improvement in the switching between broadcast delivery and unicast delivery for a streaming service in a cellular system. A method includes receiving information about a streaming service. The method also includes determining by a network entity in a radio access network whether to deliver data for the streaming service via multimedia broadcast or unicast based on the information and predetermined criteria for evaluating the information. In addition, the method includes triggering a sending of the data via the multimedia broadcast or the unicast.
