摘要： A method of determining loss of IP packets that are transported over a network (102), where each IP packet comprises a number of data packets. The method comprises: i) extracting (501) a first data packet from a first IP packet (41), ii) extracting (502) a second data packet from a second IP packet, iii) retrieving (503, 504) a first sequence number from a first data packet and a second sequence number from a second data packet, where each of the sequence numbers is indicative of a sequence of data packets and has a value belonging to a set of a number of unique values, iv) calculating (505) a difference (Δcc) between the sequence numbers, and v) determining (506) a number (k) of lost IP packets, as a function of the difference (Δcc) between the sequence numbers. Related computer readable medium and customer equipment are also described.

摘要： A method and arrangement for dynamically adapting thresholds used for selecting a codec mode to be used is presented. Thresholds are adapted in response to the current received signal quality. An estimate of actual prevailing received signal quality is obtained on which the adaptation is based. The present invention can be applied either on the mobile terminal side or on the network side, working on the uplink and/or the downlink. The thresholds can be modified on the receiving side, or, when operating in the network and working on the downlink, the threshold adaptation can be initiated in the terminal.

摘要： A multi-channel linear predictive analysis-by-synthesis signal encoding method determines (S1) a leading channel and encodes the leading channel as an embedded bitstream. Thereafter trailing channels are encoded as a discardable bitstream exploiting cross-correlation to the leading channel.
