Method and arrangement for choosing a channel coding and interleaving scheme for certain types of packet data connections
First Claim
1. A method comprising:
- receiving a request for a specific communication connection over a radio interface between a mobile station and a base station of a cellular packet radio system;
as part of said requesting a specific communication connection, receiving a request message, said request message indicating a need for setting up a new radio bearer between the mobile station and the base station or changing the characteristics of an existing radio bearer between the mobile station and the base station, said request message further indicating a certain set of desired Quality of Service parameters selected based on an expected use of said specific communication connection, to be associated with said requested specific communication connection,allocating a channel coding and/or interleaving scheme for independent application to said specific communication connection based, at least in part, on said desired Quality of Service parameters;
mapping said desired set of Quality of Service parameters to said allocated channel coding and/or interleaving scheme as a part of the allocation of the channel coding and/or interleaving scheme; and
transmitting a communication of said allocated channel coding and/or interleaving scheme to the base station and the mobile station for them to independently apply said first channel coding and/or interleaving scheme for use in said specific communication connection.

Abstract
A method for choosing channel coding and/or interleaving scheme is applied in a communication connection over a radio interface between a terminal and a base station of a cellular packet radio system. A certain decision-making device allocates channel coding and/or interleaving schemes to communication connections. A request message is communicated (to the decision-making device, indicating a certain set of Quality of Service parameters associated with a certain first communication connection. The set of Quality of Service parameters is mapped to a certain first channel coding and/or interleaving scheme as a part of the channel coding and/or interleaving scheme allocation made by the decision-making device. The first channel coding and/or interleaving scheme is communicated to the base station and the terminal for them to apply said first channel coding and/or interleaving scheme in the first communication connection.

6. A method comprising:
-
receiving a request message at a decision-making device that allocates channel coding and/or interleaving schemes to communication connections over a radio interface between mobile stations and base stations of a cellular packet radio system, said request message indicating a need for setting up a new radio bearer between a mobile station and a base station or changing the characteristics of an existing radio bearer between the mobile station and the base station and indicating a certain set of Quality of Service parameters associated with a certain first communication connection; mapping said set of Quality of Service parameters to a certain first channel coding and/or interleaving scheme as a part of the connection-specific channel coding and/or interleaving scheme allocation made by the decision-making device; and transmitting a communication of said first channel coding and/or interleaving scheme to the base station and the mobile station for them to apply said first channel coding and/or interleaving scheme in said first communication connection; wherein the step of receiving a request message at the decision-making device further comprises; a1) receiving an indication, within said set of Quality of Service parameters, of high service precedence, short mean delay and short maximum delay when the request message concerns a certain communication connection for transmitting real-time speech and/or real-time video image, or a2) receiving an indication, within said set of Quality of Service parameters, of low service precedence, long mean delay and long maximum delay when the request message concerns a certain communication connection for transmitting non-real time data; and wherein mapping said set of Quality of Service parameters to a certain first channel coding and/or interleaving scheme comprises; b1) mapping the set of Quality of Service parameters indicating high service precedence, short mean delay and short maximum delay into a channel coding scheme with no retransmissions and a long interleaving length, or b2) mapping the set of Quality of Service parameters indicating low service precedence, long mean delay and long maximum delay into a channel coding scheme with retransmissions and a short interleaving length. - View Dependent Claims (7, 13, 14, 15)

8. An apparatus comprising:
-
a decision-making device configured to allocate channel coding and/or interleaving schemes to communication connections; a controller configured to receive requests for specific communication connections with base stations and mobile stations over a radio interface, said requests for specific communication connections including a request message to the decision-making device, said request message indicating a need for setting up a new radio bearer between a mobile station and a base station or changing the characteristics of an existing radio bearer between the mobile station and the base station, said request message further indicating a certain set of desired Quality of Service parameters based on an expected use of said specific communication connection, to be associated with said requested specific communication connection; wherein the decision making device is configured to allocate a channel coding and/or interleaving scheme for independent application to said requested specific communication connection based, at least in part, on said desired Quality of Service parameters, and is further adapted to map said desired Quality of Service parameters to said allocated channel coding and/or interleaving scheme as a part of the allocation of the channel coding and/or interleaving scheme; and wherein said controller is configured to transmit a communication of said allocated coding and/or interleaving scheme to the base station and the mobile station for them to independently apply said allocated channel coding and/or interleaving scheme for use in said specific communication connection. - View Dependent Claims (9, 10, 11, 12)
