摘要:
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.

Methods, apparatus, systems and computer program products are defined that provide for in-order deliver of data packets during hand-off. The aspects provide for in-order delivery at Forward Link Serving eBS/Data Attachment Point (FLSE/DAP) switch and Reverse Link Serving eBS/Data Attachment Point (RLSE/DAP) switch. As such, present aspects provide for significant improvement in the throughput of applications, such as applications relying on Transmission Control Protocol (TCP), during handoff, in such networks as Ultra Mobile Broadband (UMB) and the like.

The disclosure relates to video rate adaptation techniques that may use information from a medium access control (MAC) layer and radio link protocol (RLP) layer. The techniques may greatly reduce video delay by adjusting video encoding rate. For real-time video telephony (VT) applications, these techniques may provide graceful quality degradation and improve user experience, especially when the channel conditions degrade.
摘要:
A method for resource management in a communication network may include monitoring whether a Proxy Mobile Internet Protocol (PMIP) tunnel between a network entity and another network entity is still needed. The method may also include detecting an event which indicates that the PMIP tunnel is no longer needed. The method may also include cleaning resources of the network entity that support the PMIP tunnel.

Embodiments described herein relate to providing adaptive encoding of real-time information in packet-switched wireless communication systems. In an embodiment, a rate-adaptation unit may be configured to receive local as well as end-to-end feedback information associated with data transmission (such as data delay, packet loss, transmit power headroom, channel condition, sector loading, the amount of buffered data, etc.) from a wireless access module in communication with wireless/wired networks, and adapt the real-time information encoding in accordance with such feedback information.

Embodiments described herein relate to connected-state radio session transfer in wireless communications. A source access network controller may lock a source radio session associated with an access terminal (e.g., in response to detecting a handoff condition associated with the access terminal), where the source access network controller may be in communication with a data network. The source access network controller may also instruct a target access network controller to create a target radio session corresponding with the source radio session, and to establish a communication route between the data network and the access network via the target ANC. The source access network controller may then freeze a state associated with the source radio session and transmits the frozen state to the target access network controller. The target access network controller may subsequently unfreeze the received state and further unlock the radio session, hence resuming control of the access terminal.

Systems and methodologies are described that facilitate multiplexing communications from multiple downstream access points to one or more mobility management entities (MME). In particular, a concentrator component is provided that can establish a single transport layer connection with an MME along with multiple application layer connections over the single transport layer connection for each of multiple downstream access points and/or related mobile devices. The downstream access points and/or mobile devices can provide identifiers to the concentrator component, which can utilize the identifiers to track communications with the MME. In this regard, the MME can additionally include identifiers received from the concentrator component in subsequent communications to facilitate identifying the appropriate downstream access point and/or mobile device.
摘要:
Relays can be used to facilitate communication of a packet, such as from a base station to a mobile device. The packet can include a header that designates an intended destination for the packet. The header can transfer such that the intended destination designation can be sent with or without being decompressed at a relay. If there is more than one relay involved in communication, then the header can configure such that the header is accessible without performing decompression. However, if there is one relay stop, then the header can compress the designator in such a way that decompression should occur.
摘要:
A heterogeneous communication system enables femto Access Points (APs) to advertise handoff related information on a first Radio Access Technology (RAT), such as for receipt by a multi mode mobile device (e.g., a mobile device capable of operation on a plurality of RATs), wherein the handoff related information permits the multi mode mobile device to identify the femto access point on a second RAT. The multi mode mobile device can be connected to a macro node (e.g., a macro base station, an evolved Base Node, etc.) using the first RAT via a Wireless Wide Area Network (WWAN) air-interface (e.g., 1×, HRPD, eHRPD), while independently reading/decoding overhead messages on the second RAT for connection thereto (e.g., connection to the femto access point on the second RAT.) The second RAT can be another WWAN, a Wireless Local Access Network (WLAN) or a Personal Access Network.

Systems and methodologies are described that facilitate provisioning cell information to mobile devices via provisioning mechanisms. The cell information relates to cell characteristics within a wireless communication network. The cell information can be stored on the mobile devices and employed to detect the cell characteristics and adjust the handoff behavior based at least in part on characteristics of signals received from one or more base stations.
