Abstract: A mobile communication network includes a plurality of access nodes that can serve different roles in support of a communication session with a mobile station. An access node can serve as a connecting node that receives access requests the mobile station, as an anchor node to anchor a radio packet connection with a core network for the communication session; or as a primary node to store session information for the communication session. One or more monitoring entities monitor the availability of the access nodes and broadcast notification messages to other access nodes when an access node failure is detected. The broadcast message includes the identity of the failed access node. Other access nodes may take action to restore connections and recover session information maintained by the failed access node.

Abstract: An approach to controlling packet forwarding in a wireless communications system that helps limit the burden placed on internal communication links while maintaining some or all of the advantages of diversity gain on the reverse link. A primary base station sends its peers a forwarding control message if a packet is successfully received. If the forwarding control message is received at the peer base stations before a timer elapses, the peer base stations refrain from forwarding their versions of the packet to the call anchor. The timer's duration may be varied as appropriate, and the forwarding control message process may be bypassed for small packets and/or certain application types.

Abstract translation: 控制无线通信系统中的分组转发的方法，其有助于限制内部通信链路的负担，同时保持反向链路上的分集增益的一些或全部优点。 如果成功接收到分组，则主基站向其对等体发送转发控制消息。 如果在定时器过去之前在对等基站处接收到转发控制消息，则对等基站避免将其分组的版本转发到呼叫锚点。 定时器的持续时间可以适当地改变，并且转发控制消息进程可以被绕过小分组和/或某些应用类型。

Abstract: A wireless communication network uses a shared packet data channel to broadcast information intended for all or a subset of the mobile stations monitoring the shared channel, based on using an associated packet data control channel to identify which shared channel transmissions comprise broadcast information rather than mobile-specific packet data traffic. For example, in a 1xEV-DV wireless communication network, a base station system can be configured to send broadcast messages on a Forward Packet Data Channel (F-PDCH) based on identifying those broadcasts via an associated Forward Packet Data Control Channel (F-PDCCH). In one such embodiment, one or more Medium Access Control (MAC) IDs are designated as broadcast identifiers. Thus, the receipt of a broadcast MAC ID in one or more timeslots of the F-PDCCH by a mobile station indicates to that mobile station that the corresponding timeslot(s) on the F-PDCH carry broadcast information rather than mobile-specific packet data traffic.

Abstract: Noise is measured at one or more base stations in a mobile communication system during periodic silence periods. A periodic silence period is defined for at least one carrier that is independent of reverse link channel frame boundaries. The radio base stations transmits silence parameters defining the periodic silence period to mobile stations, which stop transmitting during the periodic silence periods. A time reference is provided to the mobile stations to synchronize the silence periods for all mobile stations.

Abstract: Techniques to configure quality of service (QoS) and utilize radio resources for a call in a WLAN are described. In an aspect, a station ensures that an access point in the WLAN is suitable for receiving service prior to performing registration to receive services via the WLAN. In another aspect, the station first requests for radio resources for traffic flows, then requests for radio resources for signaling flows, and sends signaling as best effort traffic if radio resources are not granted for the signaling flows. In yet another aspect, the station aggregates QoS for multiple applications and requests for radio resources based on the aggregated QoS. In yet another aspect, the station releases extra radio resources corresponding to the difference between the QoS granted by the WLAN and the QoS proposed by a remote terminal for the call. In yet another aspect, the station requests for the same QoS or lower from a new access point during handoff.

Abstract: Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

Abstract: A method is performed by a device. The method includes determining whether the device is allowed to attach to an operator network based at least partially on whether all access point names in a minimum access point name list are enabled in the device. The device allows itself to attach to the operator network if it is determined that the device is allowed to attach to the operator network. The device prevents itself from attaching to the operator network if it is determined that the device is not allowed to attach to the operator network. The device can wirelessly receive a command to disable an access point name in the device. If an access point name on a detach access point name list is disabled, then the device detaches from the operator network and prevents itself from reattaching until an integrated circuit card in the device is removed and replaced.

Abstract: Systems, methods and apparatus for non-optimized handoffs for wireless communication are provided. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network.

Abstract: Apparatus and methods are described herein for managing data network connections. When a gateway or user equipment receives a message indicating the active data network connections associated with the sending party, the gateway or user equipment checks a locally stored list of active data network connections to determine whether there is a match. If at least one active data network connection does not match, the receiving device sends a message to the sending party indicating the locally stored active data network connections.
