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.

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:
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.

Systems and methods for reducing interference and saving power for home Node Bs are disclosed. Home Node Bs can be configured to remain in sleep mode until needed based on various criteria, periodically operating transmit and receive components in order to detect mobile devices that may need the services of the home Node B. Mobile devices can indicate one or several target home Node Bs using one or more node identifiers within a proximity indication message. Closed subscriber group identifiers and membership data may also be included in a proximity indication message. Node or cell identities, along with membership data, may be stored in a fingerprint database or white-list on a mobile device.

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.

Methods are presented wherein a WTRU may determine, based on measurements, that it is a victim of interference from another cell such a closed subscriber group (CSG) cell. In addition, methods are presented for the UE to inform the CSG cell that UE is present and is a victim UE. Methods for informing the CSG cell may include the grant of temporary membership to a victim UE, the use of a connected WTRU as a relay, and/or indicating victim status in a control message. The indication may trigger an interference management procedure. Methods for the WTRU to stop interference management at the CSG cell, methods to allow the use of a training period by the CSG eNB to allow for non-CSG WTRUs to report their presence, and methods to indicate how to perform UE Victim Indication are also presented.

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.
