Abstract: Various example embodiments are disclosed herein. According to an example embodiment, a technique may include allocating periodic resources to a mobile station in a wireless network for transmission of voice data, receiving from the mobile station an indication of a start of a silence period, and adjusting, based on the receiving of the indication of a start of silence period, the allocating of the periodic resources from a size and period of resource for the voice data to a size and period of resource for a silence indication (SID) frame. Alternatively, in response to receiving an indication of a start of silence period, the allocating of periodic resources for the VoIP voice data may be temporarily stopped during the silence period.

Abstract: A system and method for including aggregation control information in an aggregate frame that facilitates enhanced power efficiency is provided. Aggregation control information may include lengths of frames addressed to different stations and/or transmission opportunities to different stations. A receiving station is then able to calculate an offset within the aggregate frame that identifies the position of frames addressed to the receiving station and/or offset when it can use the medium to transmit it's data. The receiving station may then enter a sleep mode and awaken at a proper time for using the medium to either receive, or transmit data on the medium. Additionally, aggregation control information may include rate information to facilitate aggregation of multi-rate data in an aggregate frame.

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.
