摘要:
A method and apparatus of performing selective internet protocol (IP) selective offload (SIPTO) or local IP access (LIPA) is disclosed. A wireless transmit receive unit (WTRU) receives a broadcast message from a Node-B. Then the WTRU receives a message from the Node-B that SIPTO service, or LIPA service is available for that WTRU. The WTRU then communicates using the SIPTO or LIPA service. A method an apparatus for receiving a paging message for SIPTO or LIPA services is also disclosed. The paging message includes an indicator that indicates that the message is for SIPTO or LIPA communications. The indicator may be a temporary mobile subscriber identity (TMSI) assigned by the network specifically for SITPO or LIPA communications. The indicator may also be a single bit designated to indicate that a paging message is a for SIPTO or LIPA traffic.

Methods and apparatus for enabling short message service (SMS) and supplementary services (SS) in a long term evolution (LTE) network via evolved packet system (EPS) mobility management (EMM) over the LTE control plane are described. In one embodiment, the radio resource control (RRC) connection signaling radio bearer (SRB) is used for SMS and SS transport over the LTE control plane between a wireless transmit/receive unit (WTRU) and a mobility management entity (MME). EMM interfaces and primitives are defined for actions towards SMS and SS entities for enabling SMS and SS services in LTE via the LTE control plane media. Message formats for SMS and SS message transport are also disclosed for sending SMS and SS messages within EMM uplink (UL) non-access stratum (NAS) transport and downlink (DL) NAS transport messages.

A method and an apparatus for operating a timer in a wireless transmit receive unit (WTRU) includes the WTRU receiving a circuit switch (CS) call request, transmitting an enhanced packet switch mobility management service request (ESR) in response to the CS call request, starting the timer in response to the transmittal of the ESR, receiving a handover command in response to the transmittal of the ESR and stopping the timer upon reception of the handover command.
摘要:
A method, wireless transmit/receive unit (WTRU), and base station for access network interworking. Temporary identity mapping rules are defined for use during access network reselection. Mapping rules for tracking area identity, routing area identity, temporary mobile subscriber identity (TMSI), packet TMSI, and S-TMSI identity are used when reselecting UTRAN, E-UTRAN, and GERAN access networks. Depending upon access network support, a WTRU may indicate a type of identity (TMSI, P-TMSI, or S-TMSI) that is included in an access network reselection request.
摘要:
Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message, in addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told, by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.
摘要:
A method and apparatus are described for providing non-packet switched service to a target radio access technology (RAT) network. A circuit switched (CS) service notification message is received by a wireless transmit/receive unit (WTRU). If the WTRU has been allocated a valid temporary mobile subscriber identity (TMSI), a paging response message including the valid TMSI is transmitted after an inter-system change is performed from a source RAT network to a target RAT network. The CS service notification message is for terminating a CS call request. The source RAT network may be a long term evolution (LTE) network, and the target RAT network may be a third generation partnership project (3GPP) network. Alternatively, if the WTRU has not been allocated a valid TMSI, a paging response message including an international mobile subscriber identity (IMSI) that identifies the WTRU is transmitted after the inter-system change.
摘要:
Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.

摘要:
Circuit switched fallback (CSFB) requests may be managed. A mobile management entity (MME) can detect one or more pending CSFB requests. In response to detecting the pending CSFB request(s), the MME can generate a message that indicates the one or more pending CSFB requests, and can communicate the message to one of a mobile switching center (MSC) and a virtual location register (VLR).
摘要:
A method and apparatus are described for transmitting service request messages in a congested network. In one embodiment, a message including a timer value may be received by a wireless transmit/receive unit (WTRU) having a timer that is set based on the timer value. Once the timer is activated, the WTRU may not attempt to transmit a service request message to a network for mobile originated (MO) services, except for MO emergency calls, until the timer expires. In another embodiment, the timer may be deactivated in response to receiving a page for a mobile terminated (MT) call. The congested network may include a mobility management entity (MME) and a mobile switching center (MSC)/visitor location register (VLR). The MME may apply a congestion control criteria to the WTRU based on whether a timer in the MME is activated or expired.
