摘要:
A method and apparatus for performing non-voice emergency services (NOVES) between a wireless transmit/receive unit (WTRU) and a public safety answering point (PSAP) is disclosed. A NOVES session may be initiated by sending a NOVES initiation request message that includes information relating to the NOVES capabilities of the WTRU, and information relating to an emergency situation. The information relating to the NOVES capabilities of the WTRU may include an indication of whether the WTRU supports a fake power-off mode, or whether the WTRU supports PSAP control. Other methods are disclosed that include a method for a PSAP combining a multiple NOVES sessions, and a method for handing over a NOVES session having multiple media streams.

A method and apparatus for providing wireless communication services, (e.g., multimedia broadcast multicast services (MBMS)), are disclosed. A wireless transmit/receive unit (WTRU) detects a plurality of target cell evolved Node-Bs (eNodeBs) that neighbor a serving cell eNodeB. The WTRU evaluates cell reselection criteria and determines a neighboring target cell eNodeB to reselect. The WTRU receives and reads master information block (MIB) and system information messages of the neighboring target cell eNodeB, and confirms that the determined neighboring target cell eNodeB is not part of a multimedia broadcast single frequency network (MBSFN). The WTRU identifies the neighboring target cell eNodeB to the serving cell eNodeB. The WTRU then receives and reads MIB messages of the neighboring target cell eNodeB again to determine whether the system information has changed and, if so, the WTRU reads the system information and reselects to the neighboring target cell eNodeB, which provides the wireless communication services.

Disclosed herein are systems and methods for handling closed subscriber group (CSG) based local/remote IP traffic offload and selective IP traffic offload. According to an aspect, a method may be implemented at user equipment (UE). The method may include determining that a service to the UE requires a predetermined quality of service (QoS). The method may also include selecting a gateway from among a plurality of gateways in response to determining that the service to the UE requires the predetermined QoS.

A method and apparatus are disclosed for prioritizing logical channels when a new transmission is performed. Logical channel resources are allocated for available data to a plurality of logical channels. A maximum bit rate (MBR) credit (i.e., token) is decremented in a buffer (i.e., bucket) associated with a particular one of the logical channels by the size of a medium access control (MAC) service data unit (SDU). The MBR credit may have a negative value. If any of the allocated channel resources remain, the logical channels are served n a decreasing priority order until the data is exhausted. A radio link control (RLC) SDU is not segmented if the whole RLC SDU fits into the remaining resources. The MAC SDU excludes a MAC PDU header and MAC padding.

A method and apparatus may be used to cancel a communication session. The apparatus may transmit a first message to initiate a communication session and then transmit a second message that indicates a request to cancel the communication session. If the apparatus determines that there is an ongoing Packet Switched (PS) session, the apparatus may continue the ongoing PS session on a current Radio Access Technology (RAT) without performing an intersystem change. If the apparatus receives a handover (HO) command, the apparatus may transmit a message to reject the HO command, or it may ignore the HO command.

A method and apparatus for generating a measurement report request including media independent handover (MIH) information at a medium access control (MAC) device for use in configuring a physical layer measurement device to measure the physical layer and generate a MIH event report are provided. The request is sent to a physical layer measurement device which is configured using the MIH information. A physical channel is then measured based on the MIH information. A MIH event is generated at the physical layer device and sent to a higher layer device.

Techniques for supporting home NodeB (HNB) mobility and virtual active set management in support of soft handover are disclosed. A source HNB may decide to initiate a relocation of a wireless transmit/receive unit (WTRU) from the source HNB to a target HNB, and may initiate an access control for the WTRU to determine whether the WTRU is allowed to receive a service provided via the target HNB. The source HNB may send an access control query to either a core network (CN) or an HNB gateway (HNB-GW) for verifying that the WTRU is allowed to receive a service provided via the target HNB. The access control query response may include access control information for all or a subset of subscriber groups that the WTRU is a member of. The WTRU may maintain a virtual active set (VAS) including at least one macro cell and at least one femto cell.

A Media Independent Handover (MIH) server communicates with nodes in a cellular network to perform handover of a wireless transmit/receive unit (WTRU) in the event of an incoming circuit-switched (CS) call. A Gateway Mobile Switching Center (GMSC) and/or Home Location Register (HLR) receive an indication of an incoming call, and may communicate with the MIH server. A determination is made regarding whether the WTRU is active in the cellular network. When required, the MIH server initiates an MIH handover of the WTRU to the cellular network. The WTRU hands over to the cellular network and receives the call. Additionally, an MIH server and a HLR communicate location information associated with a WTRU. The location information may be used by the MIH server and HLR to perform their respective MIH and HLR functionality, and/or to handover the WTRU to a cellular network in the event of an incoming CS call.

A method and apparatus are described for processing emergency calls by simplifying call setup procedures and minimizing call setup delay. In one scenario, a system information (SI) broadcast may include emergency services support information that conveys various emergency call network support levels and setup procedures. The SI broadcast is decoded to retrieve system parameters used to process an emergency call. The SI broadcast may include a bitmap or at least one information element (IE), that indicates the various emergency call network support levels. In another scenario, an extended service request message indicating circuit switched fallback (CSFB) for an emergency call is transmitted to a packet switched (PS) radio access technology (RAT) network during a PS session. An inter-system change is performed from the PS RAT network to a circuit switched (CS) RAT without a PS handover, and a CS emergency call is initiated via the CS RAT network.
