Abstract
A method for resetting a communication connection between a first communication device and a second communication device in a cellular radio system, comprising:- detecting (201, 404) the need for resetting the communication connection,- transmitting (202, 219, 408) from the first communication device to the second communication device a reset protocol data unit, RESET PDU, (203, 210, 220) indicating the need for resetting the communication connection,- performing a resetting procedure (205,422) at the second communication device, and- transmitting (206, 213,424) from the second communication device to the first communication device a reset acknowledgement protocol data unit, RESET ACK PDU, (207, 214) indicating the completion of the resetting procedure with respect to the second communication device, characterized in that it comprises inserting into said reset protocol data unit (203, 210) a reset sequence number, which is configured t0 establish an indication of an effective number of certain resetting operations associated with a certain detected need for resetting the communication connection, setting a limit for maximum number of times of attempting the resetting procedure means for increasing a hyper frame number, HFN, value if a reset . acknowledgement protocol data unit, RESET ACK PDU, is received at the first communication device from the second communication device or a reset protocol data unit, RESET PDU, is received at the second communication device from the first communication device, but not if the Reset Protocol Data Unit, RESET PDU, has a reset sequence number the value of which is the same as the value of the reset sequence number of a last already received reset protocol data unit, RESET PDU.

Claims (6)
- A method for resetting a communication connection between a first communication device and a second communication device in a cellular radio system, comprising: - detecting (201, 404) the need for resetting the communication connection, - transmitting (202, 219, 408) from the first communication device to the second communication device a reset protocol data unit, RESET PDU, (203, 210, 220) indicating the need for resetting the communication connection, - performing a resetting procedure (205,422) at the second communication device, and - transmitting (206, 213,424) from the second communication device to the first communication device a reset acknowledgement protocol data unit, RESET ACK PDU, (207, 214) indicating the completion of the resetting procedure with respect to the second communication device, characterized in that it comprises inserting into said reset protocol data unit (203, 210) a reset sequence number, which is configured t0 establish an indication of an effective number of certain resetting operations associated with a certain detected need for resetting the communication connection, setting a limit for maximum number of times of attempting the resetting procedure means for increasing a hyper frame number, HFN, value if a reset . acknowledgement protocol data unit, RESET ACK PDU, is received at the first communication device from the second communication device or a reset protocol data unit, RESET PDU, is received at the second communication device from the first communication device, but not if the Reset Protocol Data Unit, RESET PDU, has a reset sequence number the value of which is the same as the value of the reset sequence number of a last already received reset protocol data unit, RESET PDU.
- A method according to claim 1, wherein it comprises inserting into said reset protocol data unit said reset sequence number so that its value remains the same, after the need for resetting the communication connection has been detected, from the first step of transmitting from the first communication device to the second communication device said reset protocol data unit to the next step of faultlessly receiving, at the first communication device, a reset acknowledgement protocol data unit from the second communication device.
- A method according to claim 2, wherein said reset sequence number, RSN, is a single reset sequence number bit, the value of which remains the same, after the need for resetting the communication connection has been detected, from the first step of transmitting from the first communication device to the second communication device said reset protocol data unit to the next step of faultlessly receiving, at the first communication device, a reset acknowledgement protocol data unit from the second communication device.
- A method according to claim 2, wherein it comprises: - at the second communication device, checking whether a reset protocol data unit, RESET PDU, which is received at the second communication device from the first communication device and indicates the need for resetting the communication connection, has a reset sequence number the value of which is the same as the reset sequence number of an already received reset protocol data unit, which was received at the second communication device from the first communication device, and - only as a response to a negative finding in said checking, performing a complete resetting procedure at the second communication device.
- A method according to claim 4, wherein it comprises: - only as a response to a negative finding in said checking, increasing the value of a certain frame structure number at the second communication device.
- A communication device for communicating with another communication device within a cellular radio system over a communication connection, comprising: - means for detecting a need for resetting the communication connection, - transmission means for transmitting to the other communication device reset protocol data units, RESET PDUs, indicating the need for resetting the communication connection and reset acknowledgement protocol data units, RESET ACK PDUs, indicating the completion of the resetting procedure, - receiving means for receiving reset protocol data units and reset acknowledgement protocol data units from the other communication device, and - resetting means for performing a resetting procedure for the communication connection, characterized in that it comprises: - means for inserting a reset sequence number into a reset protocol data unit transmitted to the other communication device, said reset sequence number being configured to establish an indication of an effective number of certain resetting operations associated with a certain detected need for resetting the communication connection, - means for setting a limit for maximum number of times of attempting the resetting procedure, and - meansfor increasing a hyper frame number, HFN, value if a reset acknowledgement protocol data unit, RESET ACK PDU, or a reset protocol data unit, RESET PDU, is received at the communication device from the other communication device, but not if the reset protocol data unit, RESET PDU, has a reset sequence number the value of which is the same as the value of the reset sequence number of a last already received reset protocol data unit, RESET PDU.
