Abstract
A downlink signaling counter management method for a communication device is adapted to be simultaneously associated with at least two subscriber identities and to simultaneously provide radio receiving capabilities to less than all of the subscriber identities. For each decoding of a paging block for a subscriber identity, it is determined whether the paging block decoding was correct and whether a previous paging block decoding condition is fulfilled. The downlink signaling counter is updated with different values depending on this determination results, and on whether the paging block decoding was based on a maximum number of paging bursts.

A downlink signaling counter management method for a communication device adapted to be simultaneously associated with at least two subscriber identities and adapted to simultaneously provide radio receiving capabilities to less than all of the at least two subscriber identities, the method comprising:
- for each decoding of a paging block for a subscriber identity,
- determining whether a paging block decoding is correct;
- determining whether a previous paging block decoding condition is fulfilled;
- when it is determined that the paging block decoding is correct and that the previous paging block decoding condition is fulfilled, adjusting the downlink signaling counter by a first value;
- when it is determined that the paging block decoding is correct and that the previous paging block decoding condition is not fulfilled, adjusting the downlink signaling counter by a second value;
- when it is determined that the paging block decoding is not correct, that the paging block decoding was based on a maximum number of paging bursts, and that the previous paging block decoding condition is fulfilled, adjusting the downlink signaling counter by a third value;
- and
- when it is determined that the paging block decoding is not correct, that the paging block decoding was based on a maximum number of paging bursts, and that the previous paging block decoding condition is not fulfilled, adjusting the downlink signaling counter by a fourth value,
- wherein the adjustment by the first and second values adjusts the downlink signaling counter away from a condition for triggering a downlink signaling failure event and the adjustment by the third and fourth values adjusts the downlink signaling counter towards the condition for triggering the downlink signaling failure event.
A downlink signaling counter, DSC, management system for a communication device adapted to be simultaneously associated with at least two subscriber identities and adapted to simultaneously provide radio receiving capabilities to less than all of the at least two subscriber identities, the system comprising:
- a paging decoding unit configured to decode paging blocks for each of the subscriber identities;
- a downlink signaling counter configured to update a DSC value for each of the subscriber identities;
- and
- a determination unit configured, for each of the subscriber identities,
- to determine whether a paging block decoding was correct;
- to determine whether a previous paging block decoding condition is fulfilled;
- when it is determined that the paging block decoding is correct and that the previous paging block decoding condition is fulfilled, to cause the downlink signaling counter unit to update the DSC value with a first value;
- when it is determined that the paging block decoding is correct and that the previous paging block decoding condition is not fulfilled, to cause the downlink signaling counter to update the DSC value with a second value;
- when it is determined that the paging block decoding is not correct, that the paging block decoding was based on a maximum number of paging bursts, and that the previous paging block decoding condition is fulfilled to cause the downlink signaling counter to update the DSC value with a third value;
- and
- when it is determined that the paging block decoding is not correct, that the paging block decoding was based on a maximum number of paging bursts, and that the previous paging block decoding condition is not fulfilled to cause the downlink signaling counter to update the DSC value with a fourth value,
- wherein the adjustment by the first and second values adjusts the downlink signaling counter away from a condition for triggering a downlink signaling failure event and the adjustment by the third and fourth values adjusts the downlink signaling counter towards the condition for triggering the downlink signaling failure event.
