  • Publication number: 20160295504
    Abstract: Methods and apparatus may be used for selecting power saving mechanisms in a wireless transmit/receive unit (WTRU). For example, a WTRU may support at least power saving mode (PSM) and/or extended discontinuous reception (eDRX) mode. The WTRU may send a request message including parameters associated with the supported power saving mechanisms, such as an active time for PSM and a preferred DRX value for eDRX mode. The WTRU may receive an accept message including at least one selected parameter indicating the power saving mechanism for the WTRU selected by the network (NW). The WTRU may activate the selected power saving mechanism, and may start a validity timer to define the duration of use of the selected power saving mechanism. In another example, a WTRU configured to use eDRX may receive paging signals for system information (SI) change over a prolonged Broadcast Control Channel (BCCH) modification period.

  • Patent number: 9445318
    Abstract: Method and apparatus for providing inbound mobility to closed subscriber group (CSG) and hybrid cells are described. A wireless transmit/receive unit (WTRU) reads the cell global identity (CGI) of a neighbor cell and reports it to a network of CSG cells. The network maps the CSG cell's physical cell identity (PCI) to the CSG CGI and, if required, requests the WTRU to read the CGI at handover.

  • Patent number: 9426305
    Abstract: An apparatus and method are described for sponsoring service and preferential traffic handling, (i.e., data connectivity) by wireless transmit/receive units (WTRUs). A first WTRU may initiate user sponsoring of a second WTRU via an application server (AS). The first WTRU may receive a service trigger from the AS and forward the service trigger to the second WTRU. The second WTRU may then initiate a sponsored session with the AS using the service trigger in order to receive a service from the AS. The first WTRU may also request the AS to transfer a credit to the second WTRU. The AS may establish a direct communication link with a charging system including an online charging function (OCF) and a charging data function (CDF). The AS may send a request to a network to provide preferential traffic handling needed to deliver content to the second WTRU.

  • Patent number: 9426698
    Abstract: Methods and apparatus for transmitting extended service request messages in a congested network are described. An apparatus includes a timer, a receiver and a processor. The receiver receives a message that includes a timer value. The processor sets the timer based on the timer value, activates the timer, and attempts mobile-originated circuit switched fallback for an emergency call during a period that corresponds to the timer value and during which mobile-originated circuit switched fallback is otherwise prohibited.

  • Patent number: 9426756
    Abstract: Method and apparatus are disclosed for determining a physical uplink power level for transmissions on a physical uplink channel. In one embodiment, a random access channel (RACH) uplink message is transmitted. The RACH uplink message includes a RACH message power level and/or a downlink pathloss figure. A downlink message including a power offset value is received. The physical uplink power level is set for transmissions on the physical uplink channel based on the power offset value. In another embodiment, a RACH uplink message is transmitted and a downlink message including a relative power offset value is received. The physical uplink power level for transmissions on the physical uplink channel is then set based on the relative power off set value.

  • Patent number: 9398555
    Abstract: 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.

  • Patent number: 9312992
    Abstract: A method and apparatus for implementing data security and automatic repeat request (ARQ) in a wireless communication system are disclosed. Cipher entities are included in a wireless transmit/receive unit (WTRU) and an access gateway (aGW), and outer ARQ, (or radio link control (RLC)), entities are included in the WTRU and an evolved Node-B (eNode-B). Each cipher entity is located on top of an outer ARQ entity. The cipher entities cipher and decipher a data block by using a generic sequence number (SN) assigned to the data block. The outer ARQ entities may segment the ciphered data block to multiple packet data units (PDUs), may concatenate multiple ciphered data blocks to a PDU, or may generate one PDU from one data block. The outer ARQ entities may segment or re-segment the PDU when a transmission failure occurs.
