Abstract: Providing for establishment of local Internet Protocol access (LIPA) for cellular communication is provided herein. According to particular aspects of the subject disclosure, provided are mechanisms to identify a request to establish a packet network connection as a request for a LIPA context. Once identified, a local gateway associated with the UE or with a subscriber-deployed base station is identified, and a packet context is established to support LIPA traffic for the UE. Additional mechanisms support UE mobility from one base station to another, including identifying and terminating inactive LIPA contexts. Further, a UE is described that can recognize and facilitate the establishment of a LIPA context for applications executing at the UE.

Abstract: Systems and methodologies are described that facilitate supporting mobility for UEs and relay eNBs in split-cell relay configurations. Parameters regarding communicating with one or more UEs can be provided to disparate eNBs from a donor eNB to provide mobility for one or more of the UEs or a serving relay eNB. In addition, a donor eNB can request establishment of one or more radio bearers at a target relay eNB for continuing communications with one or more UEs. Moreover, a donor eNB can provide information regarding one or more core network bearers to a target donor eNB to facilitate establishing the core network bearers at the target donor eNB for communicating with the one or more UEs. Furthermore, uplink buffer contents from a relay eNB can be provided to a target donor eNB so communications from the one or more UEs can be continued by the target donor eNB.

Abstract: Systems and methodologies are described that facilitate packet routing among relay nodes in a wireless network. Bearer quality of service (QoS) mapping is provided for internet protocol (IP) relays by utilizing differentiated services (DiffServ) code point (DSCP) values to determine a bearer for communicating related packets. In addition, SDF filtering at a gateway node can be modified to route packets over certain tunnels to provide QoS for the packets.

Abstract: Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. Packet data convergence protocol (PDCP) layer communications from a user equipment (UE) can terminate at a donor evolved Node B (eNB) and vice versa. In this regard, relay eNBs can forward PDCP layer communications over a routing protocol without locally processing the layer. The relay eNBs can, however, retrieve one or more parameters from a header of the PDCP layer for feedback to the donor eNB to assist in flow control, sequence number status transfer, and/or the like. In addition, routing identifier can be utilized to determine relay eNBs for receiving the packets. The routing identifier can additionally include an identifier of a radio bearer of the relay eNB communicating with the UE over which the PDCP layer communications are to be transmitted.

Abstract: Systems and methodologies are described that facilitate compressing headers for internet protocol (IP) relay nodes. In particular, a plurality of IP headers in a packet and at least one tunneling protocol header can be compressed to facilitate efficient communications of packets between IP relay nodes and/or a donor access point. In addition, IP relay nodes can be limited in a number of upstream bearers and can provide a greater number of downstream bearers. In this regard, the IP relay nodes can compress headers for upstream packets related to one or more downstream devices utilizing disparate context identifiers for the upstream packets. Thus, the upstream packets can be distinguished from each other while sent over the same upstream bearer.

Abstract: Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. Packet data convergence protocol (PDCP) layer communications from a user equipment (UE) can terminate at a donor evolved Node B (eNB) and vice versa. In this regard, a relay application protocol (RAPP) layer is defined to transport application layer control data among relay eNBs to facilitate appropriate routing. RAPP layer messages can be similar to control messages at other application layers, such as S1-AP, X2, etc., while additionally including a relay UE identifier for routing the messages among relay eNBs. In addition, RAPP layer messages can exclude other parameters normally defined in other application layers to protect security and encryption/decryption details.

Abstract: Systems and methodologies are described that facilitate communicating inter-eNB packets among eNBs in a cluster implemented by a donor eNB. A relay eNB can report an address received from a gateway upstream to one or more eNBs. The one or more eNBs can store the address along with one or more parameters for communicating with the relay eNB. In this regard, disparate eNBs can communicate with the relay eNB by specifying the address in an inter-eNB packet, and upstream eNBs can route the inter-eNB packet to the relay eNB based at least in part on locating the address in a routing table. In this regard, the inter-eNB packets need not pass through the gateway to reach the relay eNB.

Abstract: Systems and methods are disclosed to enable multiple neighbour base stations or access points (APs) preparation for handover robustness. The systems and methods include generating a handover request message at a source base station (BS) for user equipment (UE) if the UE detects at least one neighbour BS. The handover request message may include a handover imminent flag. The handover request message is transmitted to the neighbour BS, wherein if the handover imminent flag indicates that the handover is not imminent, the neighbour BS does not reserve a radio network temporary identifier (RNTI) for the UE.

Abstract: Systems and methodologies are described that that facilitate resource reclamation in a wireless communications system having a disjoint serving sector configuration. A mobile device can report activity on a communication link (e.g., forward link or reverse link) to a serving sector that provides a corresponding communication link. For instance, forward link activity can be reported to a reverse link serving sector and/or reverse link activity can be reported to a forward link serving sector. The activity can be analyzed to ascertain overall activity of a mobile device. Based upon the analysis, a serving sector can de-allocate resources to the mobile device.

Abstract: Certain embodiments of the present disclosure propose methods for supporting multicarrier in a radio link control (RLC) communication layer. The proposed methods reduce the processing required when scheduling information for each carrier becomes available by generating protocol data units (PDUs) in advance, and storing the PDUs in buffers associated with each carrier.

Abstract: Receiver diversity in a wireless device is controlled in response to operating conditions, transmission requirements, and control settings. The control of diversity reduces power consumption by enabling receive diversity on given conditions. Operating conditions, transmission requirements, and control settings are used separately or used in conjunction to determine whether benefits of multi-antenna receive diversity, such as higher link capacity, higher data throughput, lower transmit power, and lower error rate, warrant the higher power cost of the diversity.

Abstract: Systems and methodologies are described that facilitate fetching a native security context between network nodes in a core network after an inter-system handover of a mobile device. For instance, a mobility message that is integrity protected by a security context (e.g., the native security context, a mapped security context, . . . ) can be obtained at a network node from the mobile device. Further, the network node can send a request to a disparate network node within a core network. The request can include information that can be used by the disparate network node to establish that the mobile device is authenticated. Moreover, the native security context can be received from the disparate network node in response to the request. Accordingly, the native security context need not be recreated between the network node and the mobile device.

Abstract: Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.

Abstract: Techniques for originating a voice call by a UE after performing reselection with reprioritization are described. The UE may operate in an idle mode and may camp on a first wireless network of a first radio access technology (RAT), which may not support voice service. The first wireless network may have the highest priority among all wireless networks detected by the UE. The UE may receive an indication to originate a voice call. The UE may then perform reselection from the first wireless network to a second wireless network of a second RAT by modifying the priorities of the frequencies of the first wireless network and/or the second wireless network. The UE may then originate the voice call with the second wireless network, instead of the first wireless network, in order to avoid having to perform circuit-switched (CS) fallback from the first wireless network to the second wireless network.

The method comprises transmitting a SectorParameters message over a Forward Traffic Channel Medium Access Control(MAC) in superframe number wherein the superframe number is divisible by NOMPSectorParameters, setting a SectorSignature field of an ExtendedChannelInfo message to the SectorSignature field of a next SectorParameters message, determining if a multi-carrier mode is MultiCarrierOn and transmitting the SectorParameters message on each carrier.

Abstract: Systems and methodologies are described that facilitate providing a relay protocol to facilitate communicating upper layer protocol data among relay and donor nodes. In particular, a donor node can create a relay protocol packet upon receiving data for a relay node from a core network. Donor node can indicate an assigned relay identifier in the relay protocol packet header to facilitate routing the packet among related downstream relay nodes to arrive at the appropriate relay node, which can process the upper layer protocol data. In addition, a relay node can formulate a relay protocol packet for communication to a donor node through zero or more intermediary upstream relay nodes. Similarly, the relay node can insert the assigned relay identifier in the header to allow the donor node to associate response or related packets from the core network with the relay node.

Abstract: Systems and methodologies are described that facilitate mapping multiple evolved packet system (EPS) bearers to a single relay eNB radio bearer. In particular, an upstream eNB can select a radio bearer of a downstream eNB for association to an EPS bearer; the selection can be based on a best effort match or substantially any logic. The upstream eNB can store an association between the radio bearer and EPS bearer for subsequent downstream packet routing. The upstream eNB can also provide an indication of the selected radio bearer to the downstream relay eNB to facilitate upstream packet routing therefrom. The upstream eNB can alternatively select the radio bearer of the downstream eNB for association to the EPS bearer based on a quality of service (QoS) class identifier (QCI) of the EPS bearer.

Abstract: Systems and methodologies are described that facilitate performing intra-cluster and inter-cluster reselection for relay eNBs. In intra-cluster reselection, a relay eNB can reselect a disparate relay eNB and indicate its identifier in a bearer list update message. The disparate relay eNB and upstream eNBs (including the donor eNB) can update routing tables based at least in part on the identifier. In addition, the relay eNB can provide identifiers of downstream relay eNBs to facilitate updating routing tables for those identifiers as well. In an inter-cluster reselection, relay eNBs can release connection to downstream relay eNBs and re-attach to a wireless network to receive an identifier from a new donor eNB in the new cluster. Alternatively, the relay eNB can request an identifier from the donor eNB during reselection, notify downstream relay eNBs of the reselection, and/or request identifiers for one or more downstream relay eNBs.

Abstract: Systems and methodologies are described that facilitate attaching cell relays to a wireless network. During the attachment procedure, a relay eNB can request assignment of an identifier, or a portion thereof, from a donor eNB for subsequent packet routing to the relay eNB. This can occur through one or more intermediary relay eNBs, where present. Donor eNB can assign an identifier or portion thereof (or confirm/deny an explicit identifier request from the relay eNB) and can forward establishment information downstream to the relay eNB. Donor eNB and intermediary relay eNBs, where present, can store the identifier for subsequent use in routing packets to the relay eNB. The identifier can be a terminal endpoint identifier (TEID) utilized in a tunneling protocol, a relay identifier utilized in a relay protocol, and/or the like.
