Abstract:
1. A method for communicating in a radio access technology (RAT) network, comprising: providing a first identifying number associated with a user equipment device (UE); selecting, via a processor, a second identifying number such that a first paging interval for the first identifying number is aligned with a second paging interval for the second identifying number; wherein the first identifying number comprises a first International Mobile Subscriber Identity (IMSI) and the second identifying number comprises a second IMSI; wherein the first paging interval is based on a first paging offset and the first paging offset is a function of the first IMSI; wherein the second paging interval is based on a second paging offset, the second paging offset is the same function of the second IMSI, and the selecting the second identifying number comprises selecting the second IMSI such that the first and second paging offsets are equal; wherein the selecting of the second identifying number comprises selecting the second IMSI from one of a plurality of solutions for equation (X div K) mod DRX_Cycle_Length=(Y div K) mod DRX_Cycle_Length, wherein X is the first IMSI, wherein Y is the second IMSI, wherein the DRX_Cycle_Length is a Discontinuous Reception Cycle Length, wherein K is a number of Secondary Common Control Physical Channels (SCCPCHs) configured for a cell, wherein X div K is the quotient of X divided by K, wherein Y div K is the quotient of Y divided by K, wherein (X div K) mod DRX_Cycle_Length equals the first paging offset, and wherein (Y div K) mod DRX_Cycle_Length equals the second paging offset; wherein the selecting the second IMSI further comprises selecting the second IMSI according to a relationship based on the first IMSI, the maximum value of K, a least common multiple (LCM) of all values of K, and the DRX_Cycle_Length; and associating the second identifying number with the UE, wherein the RAT comprises Universal Mobile Telecommunications System (UMTS).
