    Abstract: An Internet Protocol (IP) multimedia subsystem (IMS) network node receives a first collaborative session control signaling from a first wireless transmit/receive unit (WTRU) for an existing IMS collaborative session between at least the first WTRU and a second WTRU. The first WTRU is the initial controller of the session. The IMS network node detects that the first collaborative session control signaling from the first WTRU is degraded, and responsively initiates transfer of control of the session to the second WTRU at least in part by: transmitting an IMS-network-node-initiated collaborative session control transfer request to the second WTRU, receiving an acceptance from the second WTRU, and receiving a second collaborative session control signaling for the session from the second WTRU. The session is maintained, at least in part, through the IMS network node both before and after the second WTRU becomes the new controller.

    Abstract: Systems, methods, and instrumentalities are provided to determine routing associated with a short message. A SMS-SC may send a first routing request to a home subscriber server (HSS). The first routing request may be associated with the short message. The SMS-SC may receive a first routing reply. The first routing reply may include one of an indication that the short message is associated with a service capability server (SCS) or a first control plane routing associated with the short message. The SMS-SC may send the short message to an SCS serving node. The first routing reply may include the indication that the short message is associated with a service capability server (SCS). The SMS-SC may send a second routing request to a SCS subscription database. The SMS-SC may receive a second routing reply from the SCS subscription database, which may indicate a second control plane routing for the short message.

    Abstract: A wireless transmit/receive unit (WTRU) may communicate using a data flow that is defined according to flow identification information (FII). The WTRU may participate in the transfer of the data flow between access networks of diverse radio access technologies. The WTRU may communicate with a mobility function to obtain access network and mobility policy information. The mobility function may be, for example, an Access Network Discovery Function (ANDSF). The mobility policy information may describe the conditions by which the transfer of data flows between access networks may be permitted.

    Abstract: A method and apparatus are described for synchronizing mobile station (i.e., wireless transmit/receive unit (WTRU)) media flows during a collaboration session. Inter-WTRU transfer request messages, flow addition request messages and session update request messages may be exchanged between a plurality of WTRUs and a session continuity control application server (SCC-AS). Each of the messages may include a session description protocol (SDP) attribute line containing time synchronization information (e.g., a presentation time offset (PTO) information element (IE), a media flow group identity (ID) and a synchronization tolerance IE). The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.

    Abstract: Methods and apparatus are provided for performing group-based machine-to-machine communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in MTC groups. MTC WTRUs belonging to the same MTC group may use a group-based International Mobile Subscriber Identity (IMSI) and a group-based IP address for data transmission. Group-based network registration may be performed. A group-based IP address and radio resources may be proactively allocated for an MTC group. A master MTC may perform network registration/attachment process on behalf of the MTC group. A group of MTC WTRUs may transmit data according to staggered time windows.
