Abstract:
1. A method of transmitting from a first packet communication station to a second packet communication station information including context control information, the context control information used to maintain consistency between header compression contexts respectively associated with the first and second packet communication stations, comprising: transmitting information other than context control information between the first and second packet communication stations according to a first transmission parameter; determining that context control information is to be transmitted from the first packet communication station to the second packet communication station; in response to the determination that context control information is to be transmitted from the first packet communication station to the second packet communication station, providing a second transmission parameter according to which the context control information can be transmitted from the first packet communication station to the second packet communication station with a probability of delivery that exceeds a probability of delivery associated with said step of transmitting information other than context control information according to the first transmission parameter; and transmitting the context control information from the first packet communication station to the second packet communication station according to the second transmission parameter, wherein the first or second transmission parameter are selected from the group consisting of a factor indicating output power, channel coding rate, number of consecutive packets, and frequency of broadcasting the number of consecutive packets.
