Specific embodiment

Inventor realize it is of the invention during notice：UE can be sent out by following two gain of parameter Serving cells Send the subframe of paging information：paging DRX（Discontinuous Reception, discontinuous reception）Cycle T and Paging density indicates parameter nB；Wherein, paging DRX cycles T is the public acquiescence DRX values of cell and the exclusive DRX values of UE Smaller value, possible value is { 32,64,128,256 }；NB is the public density instruction parameter of cell, and possible value is { 4T, 2T, T, T/2, T/4, T/8, T/16, T/32 }；Based on above-mentioned parameter T and nB, such as formula（1）And formula（2）Shown, UE can To be calculated other paging resource related parameters：

N=min（T, nB）Formula（1）

Ns=max（1, nB/T）Formula（2）

Based on parameter T, nB, N and Ns, such as formula（3）And formula（4）Shown, UE can be calculated a paging DRX The radio frames and wireless sub-frame of paging information are sent in cycle：

SFN mod T= （T div N）*（UE_ID mod N）Formula（3）

i_s = floor（UE_ID/N）Mod Ns formula（4）

Wherein, SFN is the sequence number of radio frames, can determine to send the radio frames of paging information by SFN；UE_ID= IMSI mod 1024, i.e. UE_ID by UE IMSI（International Mobile Subscriber Identity, it is international Mobile identification number）Code is obtained, in FDD（Frequency Division Duplex, FDD）And TDD（Time Division Duplexing, time division duplex）In system, the different subframe index of different Ns values correspondences, and by subframe index The wireless sub-frame for sending paging information can be drawn；As shown in Table 1 and Table 2, respectively Ns values of FDD system and TDD system Correspondence subframe index table, the wireless sub-frame for sending paging information can be determined by Ns values correspondence subframe index table.
