Abstract: Methods and systems are provided for conserving resources of a wireless communication device (WCD). A WCD may be configured to operate in one of two modes while in communication with the RAN. In a high-power mode, the WCD operates with a filtering component having a first filtering bandwidth. The first a filtering bandwidth generally enables the WCD to provide high quality audio signals based on a first audio bandwidth of an audio codec. In a low-power mode, the WCD operates with the filtering component having a second filtering bandwidth. The second filtering bandwidth enables the WCD to provide a lower quality audio signal based on a second audio bandwidth having a narrower audio bandwidth than the first audio bandwidth.

Abstract: A method and apparatus for transmitting a transport network layer (TNL) address in a wireless communication system is provided.

Abstract: The techniques described herein present opportunities for service providers and/or network providers to optimize the Quality of User Experience (QoE) for data services by determining, using a broader network-based approach, the root cause of problems causing a service degradation. To determine the root cause of the problems, the techniques may collect different trace files from multiple different nodes in the telecommunications network. Each trace file includes a log of trace identifiers for numerous different data packets that have been generated, received, transmitted, relayed, and/or routed via the node in the telecommunications network, and each trace file log entry may be associated with a timestamp. Once collected, the techniques may correlate the different trace files from the multiple different nodes to identify, using a broader network-based analysis, service optimization opportunities.

Abstract: A communication method of a terminal that can operate in a relay mode or a base station mode is provided. When the terminal, having received a service from a first base station, detects that a service connection to the first base station is unavailable, the terminal searches for a second base station, which is an available neighboring base station. The terminal transmits a ranging request message including a base station identifier of the first base station to the second base station.

A transition time gap for switching from transmission to reception may be inserted to an end of the synchronization channel preamble part.

Abstract: A unique RVID is used for each spoke node to identify traffic flowing from that spoke node to the hub and from the hub to the spoke. Spoke nodes perform MAC learning on any frame containing their assigned unique RVID and only bridge traffic received on the ring to a client port if the traffic contains their assigned RVID. Thus, MAC learning at the spoke is localized to client routes, or to routes of interest that pass through the hub. The hub node learns C-VID/RVID-ringport bindings for traffic on the ring. When a frame is received on the ring, the hub will use the C-VID and RVID to determine the I-SID and forward the traffic onto the external network. When a frame is received from the external network, the hub node will use the I-SID & C-VID to determine the RVID of the spoke node, and then use the C-VID & RVID to determine, from its forwarding database, which ringport should be used to output the frame.
