Abstract: A method for downloading a multimedia file from a server (101, 201, 300, 701) to a user device (100, 200, 400, 700), at least partly via a bandwidth limited connection (202, 702), a server and a user device adapted therefore. A user device, connected to a server selects a multimedia file to be downloaded via two bit streams. In the server the selected multimedia file is divided and coded into a first, low-quality part, and into a second, high-quality part (503). When certain conditions (505) set up for the first part are fulfilled, this part is streamed via a first bit stream (506), and when certain conditions set up for the second part are fulfilled, the second part is downloaded via a second bit stream (508). In the user device, the first part is received and reproduced (603b) as a limited version, available to be played-up in real time (604), while the second part is reproduced and combined with the first part (610, in order to yield the original multimedia file.

Abstract: A method of services request in a packet switched telecommunications network comprising a Gateway GPRS Support Node (GGSN) arranged for communication with a Serving GPRS Support Node (SGSN). During activation of a subscriber session, receiving by the GGSN, from the SGSN in an Update PDP Context Request message, data comprising both 1) an Internet Protocol (IP) address and user plane tunnelling endpoint identifier (TEID) for a Radio Network Controller (RNC) and 2) an IP address and user plane TEID of the SGSN; the GGSN nominally utilizes the IP address and TEID of the RNC for the subscriber session. If an error indication is received by the GGSN indicating that the RNC has restarted, it discards the IP address and TEID corresponding to the RNC and utilizes the IP address and TEID corresponding to the SGSN, whereby the GGSN and SGSN can maintain the subscriber session in the event of an RNC restart.

Abstract: A method and apparatus that utilizes the synchronization channel (SCH) by the user equipment (UE) to obtain time synchronization information and to perform cell search. In order to perform the SCH detection, only a correlation between the known SCH signal and the received sequence is needed, hence the FFT is not involved in the synchronization step. Typically the SCH and pilot symbols are transmitted with a constant power which is the same for all base stations. Hence, based on the serving cell (SC) SCH and pilot symbols, the power relation between these signals is estimated and the ratio applied when performing time synchronization to other cells (i.e. correlation the received sequence with the SCH from that particular NC) to estimate the pilot signal strength for the NB cell.

Abstract: An objective quality assessment method for obtaining an improved estimate of a perceptual quality degradation of a processed signal, and an arrangement for executing such a method, is provided, which is executed on a processed signal and an associate reference signal. Both signals are split up into associated frame-pairs after into frames which either all or selected frame-pairs are processed further, by creating a reference residual signal and a processed residual signal for each frame-pair, calculating separate ratios of p-norms on both residual signals, and by calculating and storing a per-frame frame-pair quality estimate on the basis of the ratios of p-norms for each selected frame-pair. An objective per-signal quality estimate that is proportional to the perceptual quality Create degradation is then provided by aggregating the calculated per-frame-pair quality estimates.
