Abstract: A mobile station (100) and a compression/decompression node in a wireless network (5), preferably the GGSN 30 (30), agree on whether to apply compression/decompression, and what compression/decompression scheme to use either by pre-configuration (when the GGSN 30 is in the home network of the mobile terminal) or by signalling (when the GGSN 30 is in a visited or a roamed-to network). Additional information, such as a profile-specific dictionary, may be used to increase the compression efficiency, particularly during start-up. Dynamic data can also be accommodated. The compression/decompression may be turned on and off on a packet-by-packet basis, depending on whether the compression actually results in a smaller packet. A compressed/uncompressed indicator bit or bits can be inserted explicitly on a per packet basis, and/or the compressed/uncompressed indication can be derived implicitly.

Abstract: A “loose ACK” method by which a radio access network of a cellular network monitors wireless transmission of packets according to a layered protocol including a radio layer (near the physical layer) and an upper layer, the method including: a step (23) of slow release—in what is called normal buffer management—in which the upper layer removes from a buffer maintained by the upper layer the oldest packet in the buffer when the buffer is full and a new packet arrives, and does so independently of whether the packet being removed has been acknowledged by the radio layer of the terminal; and a step (24) of local acknowledgement in which the radio layer sends an acknowledgement to the upper layer on the occurrence of a predetermined event. The local acknowledgement can trigger either special mode buffer management or release of the buffer to a target (entity or layer).

Abstract: A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity.
