  • Patent number: 6680955
    Abstract: A timer based header compression/decompression technique and timer and reference based technique are provided. A source generates a header field, such as an RTP time stamp. A packet including the header field is sent to a compressor which calculates a compressed header field based on the header field of the packet from the source and a jitter quantity. The compressed header field is calculated by calculating a jitter effect the network before the compressor has on the transmission of packets and calculating a jitter effect the network between the compressor and a decompressor has on the transmission of packets. The packet including the compressed header field is transmitted to a decompressor which includes a local timer. The decompressor decompresses the compressed header field by calculating an approximation of the header field based on the elapsed time since the arrival of a previous packet and the field value in the previous packet.

  • Publication number: 20040010671
    Abstract: The present invention relates to a method, a memory adapter and a system for handling data in a fixed memory of a mobile device. The inventive concept provides non-volatile memory as a kind of cache memory for accessing mass storage, wherein the fixed memory comprises at least one non-volatile memory and at least one mass storage. An advantage of the invention is that in case of an unexpected power failure, the corruption of data can be avoided, which is particularly important when operating mobile devices. Further, the non-volatile memory acting as a cache memory increases the access speed of the mass storage. Moreover, from the terminal point of view, the access to the mass storage is simplified since data is only stored and retrieved from the non-volatile memory independent of the kind of mass storage combined with the non-volatile memory.

  • Patent number: 6678249
    Abstract: When employing HARQ in soft handover (SHO) in a mobile communication system, a mobile station in communication with multiple base stations is signaled by each of the base stations when a packet sent by the mobile station is correctly received. However, while one or more base stations may have received the transmission correctly, others may not have, and retransmission may be called for. To address the possibility of having to resend such a packet, the mobile station of the invention retransmits only if a selected number of the base stations received the transmission incorrectly and does not if at least one base station received the original transmission correctly. The mobile transmits at a rate selected according to a rule from data rate information or signaling received from one or more of the base stations. The network is then able to retrieve the packet from one or more of the base stations which have received it correctly and to supply it to another or others which have not.

  • Patent number: 6678531
    Abstract: According to the invention, time is divided into power correction intervals. A target power or a target energy per bit and correction step limits are determined for each base station. The parameters are signalled to the base stations. Each base station subsequently executes a power correction algorithm. Each base station compares the used transmission power or energy per bit to said target power or said target energy per bit, respectively. The result of the comparison is further divided by a predetermined number of power correction steps within said power correction interval, the number preferably equals with the number of repetitions of downlink power control commands within said power correction interval, to provide a power correction step. The power correction is then executed in combination with the downlink closed loop power control.
