摘要： In one embodiment, a relationship is determined between radio link protocol (RLP) sequence numbers in received RLP packets and real-time protocol (RTP) sequence numbers in RTP packets decompressed from the received RLP packets. An RTP sequence number associated with a compressed RTP packet is determined based on the determined relationship and at least one of the RLP sequence numbers of the received RLP packet or packets forming the compressed RTP packet. An RTP time stamp may be determined in a similar manner.

摘要： The probability of a time out and the resulting waste of channel capacity in a communication system is decreased by controlling the length of the time out period so as to minimize the number of time outs that occur. The length of the time out is based on the sum of the average channel delay and four times the deviation in the channel delay. A delay is introduced into the communication channel so as to increase the deviation in the channel delay. This results in an increase in the length of time required for a time out. As a result, the number of time outs is drastically decreased which in turn decreases the number of wasteful ramp up times that results in a more efficient use of channel capacity.
摘要翻译： 通过控制超时周期的长度来减少通信系统中超时的概率和通道容量的浪费，从而最小化发生的超时次数。 超时的长度是基于平均通道延迟和通道延迟偏差的四倍之和。 在通信信道中引入延迟，以增加信道延迟的偏差。 这导致超时所需的时间长度的增加。 因此，超时次数急剧减少，从而减少浪费的上升时间，从而更有效地利用频道容量。

摘要： A method of receiving data packets. In the method of receiving data packets, a determination is made as to whether a received data packet is received out of an expected order. If the determining step determines a received packet is out of the expected order, a time period is calculated to wait for one or more missing data packets based at least in part on an expected time of receiving the one or more missing data packets.

摘要： In one embodiment, the method includes determining, at a first network element, whether to turn on compression of a header for a packet transport protocol used for a communication flow between the first network element and a second network element. The determining is based on a type of the communication flow, and the packet transport protocol is a protocol for transport of packets between the first and second network elements. The method further includes sending a compression mode indictor to the second network element along with a context identifier. The compression mode indicator indicates the determination, and the context identifier for use in identifying the communication flow.
