Abstract: Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

Abstract: Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering/aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes.

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: A novel key management approach is provided for securing communication handoffs between and access terminal and two access points. This approach provides for securely handing off communications between an access terminal and access point without risking exposure a master key for the access terminal. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. In one aspect, a distributive key management scheme is provided in which a current access point generates a new security key (based on its own security key) that is used by the next access point with which an access terminal communicates. In another aspect, a centralized key management scheme is provided in which a central authenticator maintains, generates, and distributes new security keys (based on a master security key associated with the access terminal) to access points.

Abstract: Apparatus and methods for performing mobile-based positioning in a wireless communications system are presented. A position estimate is computed based on assistance data intended for a first position method. The mobile device ignores if a second positioning method is not specifically supported by a network and computes a position estimate using the second position method and a subset of assistance data intended for the first positioning method, which is supported by the network and is different from the second positioning method.

Abstract: An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

Abstract: The disclosure relates to techniques for maintaining minimum quality of service (QoS) communication sessions with a wireless communication device (WCD) over a data-based communication network during a hard handoff between access networks for the WCD. More specifically, the techniques determine whether a closed connection between the WCD and a first access network during a minimum QoS communication session is due to a hard handoff between the first access network and a second access network. In the case of a hard handoff, the techniques maintain open QoS reservations associated with data flows included in the minimum QoS communication session for a predetermined period of time to enable a new connection to be established between the WCD and a second access network. The techniques described herein may especially useful when performing a voice over Internet Protocol (VoIP) call over an Evolution-Data Optimized (EVDO) communication network.

Abstract: Systems and methodologies are described that facilitate providing hybrid cell access points that can support closed subscriber groups (CSG) while providing at least a minimum level of service to wireless devices excluded from the CSG. Hybrid cell access points can allow non-member wireless devices to camp and receive paging signals. Upon receiving a request for resources from non-member wireless devices, hybrid cell access points can handover the non-member wireless devices to an access point that can serve the non-member wireless devices, provide a portion of resources compared to a disparate portion provided to member wireless devices, and/or the like. In addition, hybrid cell access points can vary levels of service and downlink transmission power to provide load balancing for access points. Varying levels of service and downlink transmission power can facilitate additional functionality, such as reducing transmission power to serve member devices while mitigating interference to non-member devices.

Abstract: Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).

Abstract: Systems and methods of decoupling session management from connection management of a wireless network by enabling transfer of a session between session controllers. A session transfer component transfers ownership of a session from a source session controller to a target session controller, wherein the session transfer does not necessarily require moving the associated connections therewith. Such transfer employs a Unicast Access Terminal Identifier (UATI) that is updated to inform the related base stations regarding transfer of the session.

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: In a communication system in which a mobile station accessing the main network via a plurality of base stations, the mobile station can freely select any of the base stations as a forward link (FL) serving station. In addition, the mobile station can also freely select another or the same base station as a reverse link (RL) serving station. The mobile station has stored in its memory a plurality of routes corresponding to the plurality of base stations, with each route dedicatedly assigned to a particular base station. During handoff of one base station to another as either the FL or the RL serving station, exchanged data packets are processed in the respective routes of the base stations involved.

Abstract: Apparatus and methods for facilitating a handover of a wireless communication device on a first wireless communication network to a second wireless communication network, wherein the first and second wireless communication networks include communications protocols that are incompatible, are disclosed. The facilitation can include establishing communications between the wireless communication device and an interworking component of the second wireless communication network using a transparent tunnel through the first wireless communication network so that a message containing session information for the second wireless communication network can be exchanged. The facilitation further includes creating a profile on the second wireless communication network for a communication session between the wireless communication device and the second wireless communication network.

Abstract: Methods and apparatuses are provided that facilitate allowing position determination of devices in wireless networks with home evolved Node Bs (HeNB). An HeNB can determine its location based at least in part on positioning measurements from one or more devices. The HeNB can additionally or alternatively register its location or other location parameters with a positioning server for subsequent provisioning as assistance information for determining a device position. Moreover, a device can request assistance information related to a different base station where the HeNB is not registered with the positioning server.

Abstract: A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

Abstract: Methods and apparatuses are provided that facilitate compressing packet headers for communicating among access points. An access point can advertise compression profiles to one or more disparate access points, and the one or more disparate access points can select at least one compression profile for compressing/decompressing packets related to the one or more disparate access points and/or devices communicating therewith. The one or more disparate access points can notify the access point of the selected compression profile, a compression context identifier, and/or static data related to identifying associated packets. In this regard, the access point can compress packets that have the associated static data according to the compression profile and compression context identifier. Similarly, the access point can decompress packets from the one or more disparate access points based on the compression context identifier.
