Abstract:
The invention relates to interpreting the change in the increment of the RTP TS field as occurring either due to silence suppression for a voice flow or a change in sampling/frame rate of a video flow. By interpreting this change correctly, the value of the TS_STRIDE field in robust header compression may be correctly calculated leading to efficient header compression performance. In one aspect, there is disclosed a method of improving ROHC between an Access Network (AN) having a compressor and an Access Terminal (AT) having a decompressor, comprising providing flow information to the compressor relating to a change in the increment of an RTP TS field of a header; determining the change in the increment of an RTP TS field as occurring either due to silence suppression or due to a change in a sampling/frame rate; and taking appropriate action for TS_STRIDE.

Abstract:
The present invention comprises a method of communicating background noise comprising the steps of transmitting background noise, blanking subsequent background noise data rate frames used to communicate the background noise, receiving the background noise and updating the background noise. In another embodiment, the present invention comprises an apparatus for communicating background noise comprising a vocoder, at least one smart blanking apparatus operably connected to the vocoder, a de-jitter buffer operably connected to the smart blanker; and a network stack operably connected to the input of the de-jitter buffer and the an output of the smart blanking apparatus.
Abstract:
A method of communication performed by a base station (105) as well as a base station (105) are described. The method comprising receiving (1705) a buffer status report, BSR, comprising a first content size indicating an amount of data packets currently stored in an uncompressed buffer (205) of a user equipment, UE (115), receiving (1710) a compressed data packet from the UE (115), determining (1715) a compression gain by computing a ratio of a size of the compressed data packet and a size of a corresponding uncompressed data packet, adjusting (1720) the received BSR based at least in part on the compression gain and assigning (1725) a grant to the UE (115) based at least in part on the adjusted BSR.
Abstract:
A message may be too long to be sent all at once. For example, there may be a limit on the number of bits that can be transmitted by a device operating in a power-save mode. The disclosure relates in some aspects to sending a message over packet boundaries (e.g., several frames or sub-frames). The disclosure relates in some aspects to segmenting a Broadcast Information Block and sending the resulting segments over broadcast information window boundaries. In some aspects, this information may be sent via overhead channels. To facilitate this segmentation, information about the segmentation may be included in the information sent from the transmitter to the receiver. For example, a first segment may indicate the number of segments and subsequent segments may indicate the segment number.
Abstract:
Apparatus and methods of mobility management include identifying a target cell as an active set candidate. The apparatus and methods further include determining that a trigger adjustment condition exists, wherein the trigger adjustment condition triggers an adjustment of a timing value that indicates a sending time of a target cell add message to a serving cell. Moreover, the apparatus and methods include sending the target cell add message including the target cell to the serving cell based on determining that the trigger adjustment condition exists.
