摘要:
Disclosed herein are systems and methods for managing home nodeB (HNB) mobility in forward access channel (Cell_FACH) states. According to an aspect, a method may be implemented at a Wireless Transmit/Receive Unit (WTRU). The method may include determining whether to communicate an indication to a network node for extended measurement occasion. Further, the method may include communicating the indication to the network node in response to determining to communicate the indication.

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.

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.

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 an apparatus for operating a timer in a wireless transmit receive unit (WTRU) are described. In one scenario, the method includes the WTRU receiving a circuit switched (CS) call request and a CS service notification, transmitting an evolved packet system mobility management service request (ESR) message, starting the timer, and stopping the timer upon reception of a handover command or a cell change command to indicate a successful CS fallback procedure. In another scenario, the method includes the WTRU receiving a CS call request and a CS service notification, transmitting an ESR message including a CS call rejection indication, starting the timer, and stopping the timer upon reception of an acknowledgement that the ESR message was transmitted or received to indicate a successful CS fallback procedure.
摘要:
Disclosed herein are techniques for inhibition of allowed closed subscriber group list. According to an aspect, a method may be implemented at a wireless transmit/receive unit (WTRU). The method may include identifying a public land mobile network (PLMN) in which the WTRU is operating. Further, the method may include controlling closed group subscriber (CSG) selection based on the identified PLMN. For example, on a per PLMN basis, the WTRU may display to the user all CSGs or only CSGs in an operator CSG list.
摘要:
Method and apparatus efficiently signal and use resources for wireless communications supporting circuit switched (CS) and packet switched sessions (PS). Signaling and interaction between the wireless transmit/receive unit (WTRU), and various network entities, such as the Mobility Management Entity (MME), the Visitor Location Register (VLR), and Base Stations (BS), are used to implement circuit switched fall back (CSFB) in a PS system.
摘要:
Method and apparatus for controlling connectivity to a network for intermittent data services are disclosed. A new dormant mode is defined such that a wireless transmit/receive unit (WTRU) may transition from a connected state or an idle state to the dormant mode based on triggering conditions. The WTRU may transition from a connected state or an idle state to a dormant mode if the characteristic or the priority of the data matches a characteristics or a priority for the dormant mode and operate using configuration which is different from configuration used for the connected state or the idle state. The WTRU in the dormant mode may perform a WTRU-controlled mobility procedure. The WTRU in the dormant mode may maintain a dedicated resource, such as a cell radio network temporary identity (C-RNTI), for receiving a unicast traffic from the network.
摘要:
Methods and systems are disclosed for an evolved node-B (eNB), or home evolved node-B (HeNB), which may be a part of a communication network. The eNB or HeNB may receive a first information regarding a handover from another node of the communication network and calculate a second information based on the first information. The eNB or HeNB may provide handover information based on the second information to a node designated to receive the handover.
