  • Method and apparatus for triggering and synchronizing machine type communication devices
    Patent number: 9020540
    Abstract: Methods and apparatus for triggering and synchronizing a machine type communication (MTC) device are described. MTC devices may operate in a time controlled mode, where the MTC device attaches to a network at specified intervals to report to a network. The time controlled mode may include two time controlled cycles, a reporting cycle and a control cycle. Methods are also described for communicating the reporting and control cycles between the MTC device and the network or MTC server. These cycles may be communicated on an application layer, by an MTC server using an MTCsp interface or via MTC configuration. In addition, triggering cycles may be sent via the Non-Access-Stratum (NAS) layer by extending discontinuous reception (DRX) cycles or by allowing a network to send the cycles over a broadcast channel by defining new System information block (SIB) information.

  • Method and apparatus for synchronizing mobile station media flows during a collaborative session
    Patent number: 9014170
    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.

  • SPONSORING OF A MOBILE STATION SESSION BY ANOTHER MOBILE STATION IN A WIRELESS NETWORK
    Publication number: 20150044989
    Abstract: An apparatus and method are described for sponsoring service and preferential traffic handling, (i.e., data connectivity) by wireless transmit/receive units (WTRUs). A first WTRU may initiate user sponsoring of a second WTRU via an application server (AS). The first WTRU may receive a service trigger from the AS and forward the service trigger to the second WTRU. The second WTRU may then initiate a sponsored session with the AS using the service trigger in order to receive a service from the AS. The first WTRU may also request the AS to transfer a credit to the second WTRU. The AS may establish a direct communication link with a charging system including an online charging function (OCF) and a charging data function (CDF). The AS may send a request to a network to provide preferential traffic handling needed to deliver content to the second WTRU.

  • METHOD AND APPARATUS FOR IMPLEMENTING A HANDOFF BETWEEN RADIO ACCESS NETWORKS DEPLOYED UNDER DIFFERENT RADIO ACCESS TECHNOLOGIES
    Publication number: 20150024755
    Abstract: A method and apparatus for implementing a handoff between radio access networks (RANs) deployed under different radio access technologies (RATs) are disclosed. A wireless transmit/receive unit (WTRU) is equipped with at least two radio units to support the RATs. Each RAN sends a list of co-located RANs in the coverage area of the RAN to the WTRU. The WTRU stores the list and determines whether handoff criteria is met by one of the co-located RANs. The WTRU then initiates a handoff from a current RAN to a target RAN if the handoff criteria is met by the target RAN. Alternatively, the WTRU may send a measurement report to the current RAN, whereby the current RAN determines whether handoff criteria is met by a selected one of the co-located RANs and initiate a handoff to the selected RAN if the handoff criteria is met.

  • INTER-UNIT TRANSFER SUPPORT USING MOBILE INTERNET PROTOCOL
    Publication number: 20150003438
    Abstract: A WTRU may receive a first data flow from a source device such as a correspondence node and perform a seamless IUT such that the correspondent node is unaware that the flow has been transferred to a different WTRU. The WTRU may register with a first home agent, wherein the first home agent receives a plurality of messages addressed for a home address. The home agent may forward the messages to the WTRU at a first care-of-address. The WTRU may send a binding update to the first home agent. The binding update may comprise a second traffic selector and a second action. The second action may specify that a second message of the plurality of messages is to be forwarded to a different WTRU when the second message matches the second traffic selector.

  • Method and apparatus for handover and session continuity using pre-registration tunneling procedure
    Patent number: 8843135
    Abstract: A method and apparatus for session continuity using pre-registration tunneling procedure are disclosed. For session continuity, a tunnel is established between a multi-mode wireless transmit/receive unit (WTRU) and a core network of a target system via a source system while the WTRU is still connected with the source system. An access procedure is performed toward the target system using the tunnel. A handover is the performed from the source system to the target system once the access procedure is complete. The access procedure includes session initiation protocol (SIP) registration, authentication of the WTRU at the target system, and internet protocol (IP) configuration. The handover may be from a third generation partnership project (3GPP) system to a non-3GPP system, or vice versa.

  • METHOD AND APPARATUS FOR MANAGING CONTENT STORAGE SUBSYSTEMS IN A COMMUNICATIONS NETWORK
    Publication number: 20140237078
    Abstract: A method and apparatus for managing content storage subsystems in a communications network are disclosed. The communications network is equipped with a plurality of content storage subsystems. The content storage subsystems store local copies of content to facilitate the delivery and distribution of the content to wireless transmit/receive units, WTRUs. The network, which is equipped with a proxy server and an entry server, receives requests for content or general-purpose data referencing content and determines whether the content is stored in the storage subsystems. In addition, the network also performs content ingestion in order to store copies of the content in the storage subsystems and content modification in order to move content from one storage location to another to achieve optimal content storage and distribution.

  • METHOD AND APPARATUS FOR DELIVERY OF DATA-BASED/VOICE SERVICES OVER PICONETS AND WIRELESS LANs (WLANs) COUPLED TO 3GPP DEVICES INCLUDING PROTOCOL ARCHITECTURE AND INFORMATION ELEMENTS RELATING TO SHORT MESSAGE SERVICE (SMS) OVER WLANs
    Publication number: 20140119285
    Abstract: Method and apparatus delivering voice/data services within a piconet operating over a limited range or over a WLAN communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN. The service is short message service (SMS). Upon receipt of an SMS message, relevant routing information is retrieved. A PDGW address for the SMS message is identified and is sent to the PDGW address which identifies the WLAN user equipment (UE) for receiving the SMS and reformats the SMS message into IP format (text or encapsulation) for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN through two alternative mechanisms, i.e., SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN. The invention enhances standard 802.11 in the context of UMTS and CDMA 2000; as well as other scenarios.
