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 improved signaling. For example, certain communication systems may benefit from improved signaling before network access is revoked through a citizens broadband radio service. A method may include receiving at a network entity from a citizens broadband radio service device a warning message. The warning message may include a drop time after which communication between a network and a user equipment using the citizens broadband radio service will terminate. The method may also include triggering the performing of an action based on the warning message by the network before the drop time.

Abstract: In the area of mobile telecommunications, the performance of single radio voice call continuity (SRVCC) can be enhanced so as to provide video single radio voice call continuity (vSRVCC). Particularly, SRVCC/vSRVCC procedures can be configured for more efficient use of radio resources. A method includes receiving a query to determine in a multi-session scenario whether a last active session is a voice only session or a video session. A method also includes sending a response to the query indicating whether the last active session is the voice only session or the video session.

Abstract: Methods and apparatus, including computer program products, are provided for controlling emergency calling. In some example embodiments, there may be provided a method that includes receiving, at a user equipment, an indication for controlling whether the user equipment makes an emergency call over a fifth generation radio access technology or over another radio access technology as a fallback; and making, by the user equipment, the emergency call based on the received indication. Related systems, methods, and articles of manufacture are also described.

Abstract: Various communication systems may benefit from being able to communicate without requiring certain identifiers to be assigned. For example, certain wireless communication systems may benefit from machine type communication using mobile originated short messaging service without a mobile station international subscriber directory number. A method can include preparing, at a user equipment, a mobile originated short message service message. The method can also include identifying, in the message, a particular external identifier from a set of external identifiers assigned to an application.

Abstract: Various communications may benefit from enhancements for group communication. For example, evolved packet system including an evolved multimedia broadcast/multicast service may benefit from such enhancements. For example, a method may include preparing a list of area names, identities, or both area names and identities to a network element. Moreover, a method may also include requesting the network to broadcast data to a broadcast area defined by the list. The list can define an allowed area, a broadcast area, or both.

Abstract: A UE activates a PS Data Off service to block downlink and uplink services except the exempted services determined by the HPLMN. To activate PS Data Off, the UE sends an indication to the MME or SGSN, or additionally to a S-CSCF or an IMS network. The UE may receive a confirmation of the PS Data Off activation and/or a list of exempt services. The MME may contact the HSS to notify about the activation of the PS Data Off and receive indication of support of the service or list of exempted services and send the indication and/or packet filtering per PDN to PDN GW(s). The PDN GW may contact a PCRF to get policy rules. The HSS may provide a list of exempt services to the S-CSCF.

Abstract: Various communication systems may benefit from improved voice call support. For example, it may be helpful for a user equipment in a first radio access technology that may not support voice calls to initiate a voice call with a second radio access technology. A method includes initiating a voice call between a user equipment to an entity in a second radio access technology cell. The user equipment is located in a first radio access technology cell. The method also includes registering the user equipment with the second radio access technology cell. In addition, the method includes conducting the voice call with the entity via the second radio access technology cell.
