Apparatus, method and computer program product providing idle mode discontinuous reception

摘要

A network sends an indication of discontinuous reception period (ldle_Mode_DRX_Period) and an indication of number of paging groups (Paging_Group_Count). Paging occasions for a user equipment are determined by a predetermined formula. One exemplary formula is SFN mod IDLE_Mode_DRX_Period=(IDLE_Mode_DRX_Period div Paging_Group_Count) *(ID) mod (Paging_Group_Count); where SFN is system frame number and ID is the identifier of the user equipment, which can be IMSI or some value derived from IMSI. The UE's temporary ID is sent during a determined paging occasion, which maps to a paging channel on which the page is sent. Options for restricting the paging occasion to less than a frame, and for offsetting the paging occasions from that of the above formula are detailed.

1. A method comprising:
receiving an indication of a discontinuous reception period and an indication of a number of paging groups; determining paging occasions for a user equipment by applying the indicated discontinuous reception period, the indicated number of paging groups and an identifier of the user equipment to a predetermined formula; and monitoring a control channel during the determined paging occasions, wherein the predetermined formula comprises:
SFN mod IDLE_Mode—DRX_Period=(IDLE_Mode—DRX_Period div Paging_Group_Count)*(ID)mod(Paging_Group_Count); wherein SFN is system frame number, Idle_Mode_DRX_Period is the discontinuous reception period, Paging_Group_Count is the number of paging groups, and ID is the identifier of the user equipment which comprises an international mobile subscriber identity of the user equipment or a value derived from the international mobile subscriber identity.
