    Abstract: An authentication server may be adapted to (a) authenticate an authentication peer seeking to establish communications via a first network access node; (b) retrieve user profile information associated with the authentication peer; and/or (c) send the user profile information to a network gateway node that facilitates communication services for the authentication peer. A PMIP network node may be adapted to (a) provide wireless network connectivity to an authentication peer via a first network access node; (b) provide a PMIP key to both ends of a PMIP tunnel between the first network access node and a PMIP network node used to provide communications to the authentication peer; (c) provide the PMIP key to a first authenticator associated the first network access node; (d) receive a request at the PMIP network node from a requesting entity to reroute communications for the authentication peer; and/or (e) verify whether the requesting entity knows the PMIP key.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive data from both a source base station and a target base station during handover. For example, the UE may refrain from resetting or reestablishing media access control (MAC) and packet data convergence protocol (PDCP) layer configurations until after a successful access procedure is performed with the target base station. In some cases, a single radio link control (RLC)/PDCP stack may be used during handover procedures. A source base station may, for example, forward data to a target base station after receiving a handover execution message. A UE may identify and resolve any duplicate data sent by both base stations during the transition. Additional signaling may be used (e.g., during the radio resource control (RRC) configuration) to indicate that a UE supports dual link handover.

    Abstract: Certain aspects relate to methods and apparatus for wireless communications, comprising determining to use a reduced paging cycle to page a user equipment (UE) of a first type that supports the reduced paging cycle, the reduced paging cycle having a shorter period relative to a paging cycle used with UEs of a second type which do not support the reduced paging cycle, and paging the UE of the first type in accordance with the reduced paging cycle. Certain aspects relate to methods and apparatus for conveying system information by a base station, comprising broadcasting a first system information common to each cell of a group of cells in an area and broadcasting a second system information that can vary between cells in the group of cells, wherein the second system information is broadcast more frequently than the first system information.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a service through an MBMS session. The apparatus receives a first notification of an upcoming suspension of the MBMS session. The apparatus requests establishment of a unicast bearer prior to the upcoming suspension of the MBMS session upon receiving the first notification. The apparatus receives a corresponding unicast version of the service of the MBMS session via unicast when the unicast bearer is established. In an aspect, the first notification may be received during a first MCCH modification period, the corresponding unicast version of the service is received via unicast during a second MCCH modification period. In an aspect, the apparatus may further receive a second notification that the MBMS session is suspended during the second MCCH modification period.

    Abstract: Systems and methods for communicating in a wireless communication system are described. One implementation is provided for controlling aspects of a wireless communication system network via a traffic detection function at the user equipment. The method includes obtaining, at an electronic device, an application configuration, the application configuration including an application identifier identifying an application of a plurality of applications and a network communication characteristic corresponding to each of the plurality of applications. The method further includes detecting, at the electronic device, the application identifier in a packet of network traffic. The method also includes transmitting, from the electronic device, the packet of network traffic based on the network communication characteristic corresponding to the detected application identifier. By providing an application identifier, fine grained (e.g., application specific) network controls may be implemented such as quality of service, charging/accounting, idle handoff, and traffic redirection/load balancing.
