摘要:
A method and system for controlling access to a wireless communication medium are disclosed. The system includes at least one access point (AP) and at least one station (STA). The AP defines a superframe for transmission of data in a time domain having a high throughput (HT) period which includes at least one scheduled resource allocation (SRA) and at least one management SRA (MSRA). The AP broadcasts an extended beacon (EB) including information about the SRA and MSRA. The SRA is defined for transmitting traffic data between the AP and the STA, and the MSRA is defined for transmitting management and control data between the AP and the STA. The system reduces station battery consumption, supports higher throughput for non-real time (NRT) traffic and is more efficient for real time (RT) traffic while maintaining full compatibility.

A method and apparatus for supporting a handoff (HO) from a general packet radio service (GPRS), global system for mobile communication radio access network (GERAN), and long term evolution (LTE) evolved universal terrestrial radio access network (EUTRAN) includes receiving an LTE measurement report. An HO is initiated to the LTE network and a relocation request signal is transmitted. A relocation command signal that includes an evolved Node-B (eNB) identifier (ID) is received.
摘要:
A method and apparatus for interworking between a mobile network operator and an application provider are disclosed. A network application function (NAF) may be co-located with an OpenID provider such that an application server may communicate with the NAF to access a home subscriber server (HSS) via a bootstrapping server function (BSF). The interfaces between BSF and HSS, and between BSF and NAF may be enhanced to carry information that is available through Sh interface between the application server and the HSS. When the WTRU is roaming in a visited network, the application server may communicate with the visited network for charging and policing for serving the service request from the WTRU. The application server may be co-located with an NAF, and may authenticate the WTRU using Generic Bootstrapping Architecture, and may communicate with a BSF in a home network via an eZn-proxy function to access an HSS.
摘要:
A method for enabling coder selection and rate adaptation in a UMTS Terrestrial Radio Access Network (UTRAN)/enhanced UTRAN (E-UTRAN), the method comprising receiving a media stream from a server at a first data rate, transmitting a feedback signal to the server indicating conditions at the UTRAN/E-UTRAN, wherein the feedback signal includes an indication of available buffer space, roundtrip time, data packets received at the UTRAN/E-UTRAN, data packets played out, and an air link condition, and receiving the media stream at an adjusted second data rate based on the feedback signal transmitted to the server.
摘要:
A method and apparatus are described for performing a selected Internet protocol (IP) traffic offload (SIPTO) procedure. A network node, (e.g., a mobility management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN)), may receive a packet data network (PDN) connectivity request from a wireless transmit/receive unit (WTRU). A determination may be made to perform SIPTO at a local network, and the WTRU may perform a PDN release and reconnection procedure. The determination may be based on at least one of a closed subscriber group (CSG) identity (ID), a home evolved Node-B (HeNB) ID or a local network ID. An access network discovery and selection function (ANDSF) may be queried for IP interface selection (OPIIS) rules, a local access point name (APN) that supports per flow SIPTO at a local network, and IP flows that may be routed to the local APN.
摘要:
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.

In a wireless communication system, a wireless transmit receive unit (WTRU) adapted to bundle a plurality of services into radio access bearer (RAB) in an uplink signal and unbundle a plurality of services from a RAB in a downlink signal. The WTRU is adapted to communicate with a plurality of services through a communications tunnel.
摘要:
A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.
摘要:
A method and system for interworking between cellular networks and wireless local area networks (WLANs) are disclosed. At least one cellular network, at least one WLAN and an IP network are deployed. A wireless transmit/receive unit (WTRU) first establishes a connection to a WLAN and a tunnel between an access point (AP) and a packet data gateway (PDG) is established. The PDG further establishes a tunnel to an IP network. The WTRU then invokes a service which is delivered through the WLAN. As signal quality from the AP degrades below a predetermined threshold, a handover from the WLAN to the cellular network is performed. A new connection to the cellular network may be established either before or after breaking the current connection to the WLAN or the two connections may be maintained simultaneously.
