Determining paging location information corresponding to the paging radio frame;

The paging location is determined based on paging location information corresponding to the paging radio frame.

Determining the paging location information corresponding to the paging radio frame includes:

Determining the paging radio based on the identity (ID) number of the UE, the number of radio frames used for paging in a paging radio frame period, and the number of subframes used for paging in a paging radio frame. Paging location information of the corresponding UE in the frame.

The principle for determining the value of paging location information is:

All UEs are evenly distributed according to the ID number of the UE to a radio frame that can be used for paging in a paging radio frame period, according to which the paging radio frame of the UE can be determined;

After the paging radio frame is determined, the principle of determining the paging location information of the UE in the paging radio frame is: uniformly mapping all UEs corresponding to one paging radio frame to different homing according to the identifier ID number of the UE. Call location information. It should be noted that the number of paging location information values and one The number of subframes available for paging in a paging radio frame is the same.

Wherein, each paging location information corresponding to the paging radio frame is determined according to the following formula:

I_s=floor(UE_ID/N)mod Ns,

Where i_s is the paging location information of the paging radio frame, UE_ID is the ID number of the UE, UE_ID=IMSI mod 1024, IMSI is the international mobile subscriber identity, and N is the radio for paging in a paging radio frame period. The number of frames, Ns is the number of subframes used for paging in a paging radio frame, mod is the remainder, and floor is rounded down.

Embodiments of the present invention map i_s to multiple paging locations. The UE is evenly distributed by UE_ID into all paging subframes within one paging radio frame period. When determining the paging radio frame, the method is to uniformly distribute the UE according to the UE_ID to N radio frames (paging radio frames) that can be used for paging in a paging cycle length range, wherein the following formula is satisfied. SFN (System Frame Number) as a paging radio frame (PF):

SFN mod T=(T div N)*(UE_ID mod N),

Where T is the Paging Cycle of the paging radio frame in which the UE listens to the paging message, in units of radio frames; UE_ID is the ID (Identity) of the UE, UE_ID=IMSI mod 1024, and IMSI is International Mobile Subscriber Identity (International Mobile Subscriber Identity); N is the number of radio frames used for paging within the length of a paging cycle, mod is the remainder, and div is the divisor;

In the embodiment of the present invention, by configuring multiple paging locations in a paging radio frame, the UE can have more paging opportunities, thereby reducing the delay.

A method for a UE to configure multiple paging locations in a paging radio frame is as follows:

Step 1: After determining a paging message for the network transmitting UE and a paging radio frame (PF) for the UE to listen to the paging message, calculate a paging available in the paging radio frame for the network transmitting UE The information and the information i_s, i_s of the paging position at which the UE listens to the paging message are calculated as follows:

I_s=floor(UE_ID/N)mod Ns,

Where i_s is the paging location information that can be used for paging of the UE in the paging radio frame, and the location of the downlink subframe that i_s can use for paging has a certain correspondence, and the location of the downlink subframe used for paging is The form of the sub-frame number is embodied. UE_ID is the ID (Identity) number of the UE, UE_ID = IMSI mod 1024; N is the number of radio frames available for paging within a paging cycle time length; Ns is a paging radio frame (PF) available for paging The number of sub-frames.

Optionally, there are two options for determining the number of subframes Ns that can be used for paging in a paging radio frame (PF):

Solution 1: Ns=max(1, nB/T), where nB is a cell broadcast by the system, and the value range may be {4T, 2T, T, T/2, T/4, T/8, T/. 16, T / 32}, at this time the maximum value of Ns is 4;

Solution 2: Further increasing the value range of the number of subframes Ns available for paging in a paging radio frame (PF), optionally by increasing the value range of the cell nB in the system broadcast. The value range of nB includes values greater than 4T, such as the range of {10T, 4T, 2T, T, T/2, T/4, T/8, T/16, T/32}. Moreover, considering that Ns is limited by the number of downlink subframes N_dlsf in one radio frame, the method for determining Ns may be Ns=Min(max(1, nB/T), N_dlsf), and for FDD mode, N_dlsf=10, For TDD mode, N_dlsf needs to be determined according to UL/DL Configuration.

Step 2: After determining the paging message available for the network transmitting UE in the paging radio frame and the information i_s of the paging location of the paging message of the UE, the mapping relationship between the i_s and the paging location PO may be adopted. A paging message available in the paging radio frame for the network to transmit the UE and a paging location PO in which the UE listens to the paging message are determined. A paging location information can be mapped to one or more subframes.

Let the number of POs to which an i_s is mapped be Npo, and the number of subframes that can be used for paging in a radio frame is Ns, then 1<=Npo<=Ns. According to Ns and Npo, the mapping relationship between i_s and PO can be obtained. Among them, Npo can be configured by the network or fixed to a certain value.

When the maximum value of Ns is 4 (that is, in step 1, when the Ns scheme is determined), the value of Npo may be {1, 2, 4}, and the mapping relationship between i_s and PO may be selected as :

FDD (Frequency Division Duplexing) system:

Ns	Npo	PO when i_s=0	PO when i_s=1	PO when i_s=2	PO when i_s=3
1	1	9	N/A	N/A	N/A
2	1	4	9	N/A	N/A
2	2	4,9	4,9	N/A	N/A
4	1	0	4	5	9
4	2	0,5	4,9	0,5	4,9
4	4	0,4,5,9	0,4,5,9	0,4,5,9	0,4,5,9

among them,

Ns is the number of paging subframes in a paging radio frame;

I_s is the "position indication information of the paging subframe" calculated according to the formula;

PO (Paging Occasion) is the "Paging Subframe Position" and is the subframe number in the paging radio frame.

If Ns=2, and the calculated i_s is 0, according to the above mapping table, PO is 4 when Npo=1, indicating that the subframe numbered 4 in the paging radio frame is used as the paging subframe of the UE. . On the other hand, when Npo=2, PO is 4 and 9, indicating that two subframes numbered 4 and 9 in the paging radio frame are used as paging subframes of the UE.

TDD (Time Division Duplexing) system (all UL/DL configurations):

Ns	Npo	PO when i_s=0	PO when i_s=1	PO when i_s=2	PO when i_s=3

2	1	0	5	N/A	N/A
2	2	0,5	0,5	N/A	N/A

In different uplink and downlink configurations, downlink subframes in one radio frame. The distribution is different. Here, "all" means that this table is suitable for all uplink and downlink configurations, and the query mode is consistent with the FDD system.

When the maximum value of Ns is greater than 4 (that is, when the Ns scheme 2 is determined in step 1), after the number of subframes used for paging in one radio frame is increased, the mapping relationship between i_s and PO can still adopt a fixed mapping. The way the table is queried. The number of POs that can be mapped by an i_s can be {1, 2, 4, 10}. In this case, the mapping table of i_s and PO can be selected as shown in the following table.

TDD (all UL/DL configurations):

It should be noted that the actual Npo is less than or equal to Ns, that is, for the TDD mode, if the configured Npo is equal to 10, which is greater than the number of downlink subframes that can actually be provided in one radio frame, all downlink subframes are indicated. Both can be used as PO.
