Abstract: The number of handover-related failures that occur in a communication system may be reduced by taking target access point conditions into account when declaring radio link failure and/or by delaying certain handover operations. In some aspects, criteria for radio link failure detection and access terminal-controlled mobility may take into account access point parameters related to neighboring cells that may be available as mobility targets. For example, filtering mechanisms for detecting radio link failure based on radio layer problem reports may also take into account the availability of various neighbor access points and their measured signal strengths. In addition, a handover command may be sent earlier than in conventional systems (e.g., the handover command may be sent even though the target access point is weaker than the source access point) and include an indication that instructs the access terminal to delay handover until a specified condition is met.

Abstract: Devices and methods are provided for the patching of a UE context via retrieval of partial contexts when a UE transitions from a source system (e.g., UTRAN) to a target system (e.g., an LTE network). In one embodiment, the method may involve receiving a first identifier for a source system server (e.g., SGSN) storing first context information, and a second identifier for a target system server (e.g., MME) storing second context information. The method may involve retrieving and combining the first and second context information to generate the patched context for the UE.

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.

Abstract: Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. A donor eNB can create at least a portion of a tunnel endpoint identifier (TEID) for a relay eNB communicating with a UE or other device. In addition, the relay eNB communicating with the UE can create a portion of the TEID. Upon receiving packets with a TEID, the donor eNB can route the packets to downstream eNBs based on the portion of the TEID that it created. Other downstream eNBs can continue to route packets to next hop eNBs based on the portion of the TEID created by the donor eNB or the downstream eNBs themselves. The relay eNB communicating with the UE can route packets to the UE based on the portion of the TEID it created and/or the portion created by the donor eNB.

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 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: Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

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 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.

Abstract: Systems and methodologies are described that facilitate compressing packet headers for cell relay communications. Since cell relays can support a number of evolved packet system (EPS) bearers over a given dedicated radio bearer (DRB), robust header compression (RoHC) can be multiplexed for communications to/from a given cell relay. Thus, an upstream node compressing one or more packet headers can indicate a RoHC context, which can be represented by a RoHC context identifier in a RoHC header. A receiving entity can decompress the headers based on determining the RoHC context. Alternatively, the RoHC context can be associated with an identifier of a related UE bearer such as a tunnel endpoint identifier (TEID), a relay identifier, and/or the like, that is received in a tunneling protocol header to facilitate packet routing.

Abstract: Systems and methodologies are described that facilitate assigning TEIDs, or portions thereof, to UEs or other devices during network attachment and/or dedicated bearer activation using one or more cell relays. Relay eNBs can request bearer establishment from a UE, which can be based on receiving an attach accept from an upstream node during attachment for the UE, receiving a bearer setup request from the upstream node, and/or the like. Once a bearer establishment response is received from the UE, the relay eNBs can store a TEID relating to the bearer. This can be a TEID that is at least partially received in the attach accept or bearer setup message, generated for the UE upon receiving the bearer establishment response, and/or the like. The TEID, or portion thereof, can be utilized for subsequent packet routing to the UE through one or more cell relays.

Abstract: Apparatus and methods of hand-in of a call from a macro node to a femto node include receiving, at a target interface to a plurality of access points, a handoff request to handoff a call of a mobile station, wherein the handoff request comprises a cellular identifier corresponding to a pilot identifier of a pilot signal. Further, the apparatus and methods include determining that the plurality of access points share the cell identifier, and forwarding the handoff request to the plurality of access points that share the cell identifier. Additionally, the apparatus and methods include generating a handoff request acknowledgement comprising a pre-reserved resource that is common to the plurality of access points, wherein the pre-reserved resource enables the mobile station to communicate with the plurality of access points, and transmitting the handoff request acknowledgement to initiate the hand-in to one of the plurality of access points.

Abstract: Systems and methods for communication include components and methods for detecting, at an access point base station, location-verification data transmitted by at least one macro cell. Further, the components and method include transmitting a response message, including location information, via a backhaul network to a location authentication component to authenticate a location of the access point base station based on the location information, wherein the location information includes location data that is a function of the location-verification data. In some aspects, an operation of the access point base station may be allowed or disallowed based on an authentication of the location information.

Abstract: A method for establishing a radio resource control connection is disclosed. A wireless communication device may establish a radio resource control connection with a first base station. The wireless communication device may send a message to a second base station that requests re-establishment of the radio resource control connection. The wireless communication device may receive a message from the second base station that initiates setup of a new radio resource control connection.

Abstract: A method for synchronizing a wireless communication system is disclosed. A silence duration for a base station is determined based on the time required for a neighbor base station to obtain or maintain synchronization. All transmissions from the base station are ceased for the silence duration. Multiple base stations level may cease transmissions at the same time, thus mitigating interference.

Abstract: Paging load and/or registration load in a network is reduced by using different types of identifiers to specifying which nodes page an access terminal in the network. In some aspects, the network maintains a list that specifies that certain individual nodes (e.g., cells or sectors) are to page a given access terminal and/or that one or more zones (e.g., tracking areas) are to page the access terminal. In some aspects, an access terminal in a network may be configured to provide a forward-looking paging list to the network. The list provided by an access terminal may specify different types of node identifiers (e.g., individual node identifiers, subscriber groups, etc.). The network may then use the list to determine which nodes are to page a given access terminal such that when the access terminal moves to a different node, that node may already be configured to page the access terminal.

Abstract: A method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. A receiver receives a first broadcast controller identification from a first base station, and a second broadcast controller identification from a second base station. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services.

Abstract: Systems and methodologies are described that facilitate synchronizing base stations in a wireless communication environment. A base station can receive a synchronization signal sent via a low reuse channel, which can be shared by a group of base stations. Further, the base station can align a clock associated therewith to the received synchronization signal. Moreover, the base station can coarsely align the clock to a first synchronization signal received upon a first subset of resources of the low reuse channel, and finely align the clock to a second synchronization signal received upon a second subset of resources (e.g., of the low reuse channel, of a separate channel, . . . ), where the second subset of resources can be reserved for transmission from at least one base station with at least a predetermined level of synchronous accuracy.

Abstract: Systems and methodologies are described that facilitate providing relay nodes in wireless networks. In particular, cluster nodes, which can be regular eNBs, can provide wireless network access to the relay nodes over a backhaul link, and the relay nodes can offer access to devices or other relay nodes to expand network coverage and/or provide increased throughput. User equipment (UE) relays can function as UEs according to a cluster node such that UE relays receive network addressing and can tunnel communications through the cluster node using the backhaul link. Cell relays can function as a cell of the cluster node, such that transport layer communications terminate at the cluster node. In this regard, cell relays can define transport layers to use in communicating with the cluster nodes over the backhaul and with other devices over a provided access link.
