Abstract
A retransmission correction performed by counting means (70) provided in a controlling radio network controller (RNC) (4a-c) within a radio access network (3) in the counting of multimedia service joined mobile terminals (7) located in a cell (6) for a PTP/PTM transmission decision, in the case of a repetition of a multimedia service session. The retransmission correction uses an estimated number of the mobile terminals having received a previous transmission of said multimedia service session from any radio network controller.
Claims24
A method in a controlling radio network controller (RNC) within a radio access network for counting of multimedia service joined mobile terminals located in a cell for a PTP/PTM transmission decision, characterised by a retransmission correction of a counted number of mobile terminals in case of a repetition of a multimedia service session, using an estimated number of the mobile terminals having received a previous transmission of said multimedia service session from any radio network controller, said retransmission correction comprising the steps of:
- Receiving a repetition indicator in the multimedia session start notification from the core network;
- Collecting PTP/PTM information regarding previous transmissions of said multimedia service session stored in the mobile terminal contexts and in mobile terminal links received from serving radio network controllers;
- Calculating a repetition correction value using said collected PTP/PTM information;
- Correcting a counted number of multimedia service joined mobile terminals using said repetition correction value;
- Storing said repetition indicator and PTP/PTM information regarding said repetition of the multimedia service session in the mobile terminal contexts and in mobile terminal links transferred to serving radio network controllers .
A radio network controller capable of functioning as a controlling radio network controller (CRNC) within a radio access network, the radio network controller provided with counting means for counting of multimedia service joined mobile terminals located in a cell for a PTP/PTM transmission decision, characterised by the counting means comprising retransmission correction means ( arranged to correct a counted number of mobile terminals in the case of a repetition of a multimedia service session, using an estimated number of the mobile terminals having received a previous transmission of said multimedia service session from any radio network controller, wherein the retransmission correction means further comprises:
- Reception means for receiving a repetition indicator in the multimedia session start notification from the core network;
- Collection means for collecting PTP/PTM information regarding previous transmissions of said multimedia service session stored in the mobile terminal contexts and in mobile terminal links received from serving radio network controllers;
- Calculating means for calculating a repetition correction value using said collected PTP/PTM information;
- Correction means for correcting a counted number of multimedia service joined mobile terminals using said repetition correction value;
- Storing means ( for storing said repetition indicator and PTP/PTM information regarding said repetition of the multimedia service session in the mobile terminal contexts and in mobile terminal links transferred to serving radio network controllers .
