Detailed ways

As mentioned in the background art, in the prior art, if paging is performed according to the mode of the highest paging demand of the terminal, the paging resources will be wasted.

To solve the above problem, an embodiment of the present invention provides a paging method. The method includes: determining a target paging frame corresponding to the terminal according to a terminal type of the terminal; and monitoring a paging message in the determined target paging frame.

Thus, different paging strategies can be implemented for different types of terminals according to different paging requirements of the terminals, so as to save paging resources.

In order to make the above objects, features and beneficial effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a paging method according to an embodiment of the present invention. The method may specifically include the following steps:

Step S101, determining a target paging frame corresponding to the terminal according to the terminal type of the terminal;

The terminal is also called terminal equipment or user equipment (User Equipment, UE for short).

The terminal type is a type obtained by classifying terminals according to the paging requirements of each terminal. Optionally, the terminal type may be classified according to at least one of the following associated information of the terminal: Coverage Enhancement Level (CE Level for short), number of repetitions, and discontinuous reception (Discontinuous Reception, DRX for short) period.

The number of repetitions is the number of repetitions of data transmission between the terminal and the network. For example, the number of repetitions of sending a Physical Downlink Control Channel (PDCCH for short)/sending a Physical Uplink Control Channel (PUCCH for short).

Taking the coverage level as the division basis of the terminal type, the index Cate _index of the terminal type can be obtained from the mapping relationship in the following Table 1:

Table 1

Cate _index Cate _index	Ncate＝2Ncate=2	Ncate＝2Ncate=2	Ncate＝2Ncate=2	Ncate＝3Ncate=3
00	CE Level 0 CE Level 0	CE Level 0 CE Level 0	CE Level 1 CE Level 1	CE Level 0 CE Level 0
11	CE Level 1 CE Level 1	CE Level 2 CE Level 2	CE Level 2 CE Level 2	CE Level 1 CE Level 1
22				CE Level 2 CE Level 2

Wherein, Ncate is the total number of terminal types supported on the current paging resource. CE Level 0, CE Level 1 and CE Level 2 are the three levels of CE Level respectively.

The target paging frame is a wireless paging frame used by the terminal, and the terminal monitors the paging message in the target paging frame. The target paging frame is related to the terminal type of the terminal. Optionally, a mapping relationship (eg, a mapping table) between the terminal type and the target paging frame may be set, so as to determine the target paging frame corresponding to the terminal type of a terminal according to the mapping relationship.

Optionally, for a terminal capable of determining the target radio frame according to the terminal type, if the base station also supports the corresponding capability, if the terminal receives the instruction information sent by the base station to perform step S101, the terminal determines the target paging frame according to step S101. Optionally, the indication information is carried by a system message, such as a system information block (System Information Blocks, SIB for short) or a master information block (Master Information Block, MIB for short). Further, the indication manner of the system message includes:

1) Explicitly indicate whether the corresponding capability is supported through a system message, such as adding a 1-bit indication cell, and indicating whether the corresponding capability is supported through different values (eg, 0 or 1) of the cell.

2) Implicitly indicate that the corresponding capability is supported through the system message, that is, if the configuration information related to the corresponding capability is configured in the system message, that is, the support of the capability is implicitly indicated, otherwise, it is not supported.

There is indication information in the broadcast system message that indicates that the base station has differentiated paging according to the paging radio frame;

Step S102, monitoring the paging message in the determined target paging frame.

After the terminal determines the target paging frame corresponding to itself, the target paging frame is regarded as a wireless paging frame for monitoring the paging message by itself, and paging monitoring is performed on the target paging frame.

The method shown in FIG. 1 is performed by the terminal side, and through this method, the corresponding radio paging frame is determined according to the terminal type, which is called a target paging frame. The base station uses the target paging frame to send a paging message to the terminal, and the terminal monitors the paging message in the target paging frame. Thus, the network side can design different paging strategies on different target paging frames, so as to implement different paging strategies for terminals of different terminal types according to different paging requirements of the terminals, thereby saving paging resources. Further, the network side can reduce the paging delay of terminals in some terminal types by designing different paging strategies for different terminal types.

In one embodiment, in step S101 in FIG. 1 , determining the target paging frame corresponding to the terminal according to the terminal type of the terminal includes: determining the initial paging frame corresponding to the terminal according to the terminal identifier of the terminal; The initial paging frame and the terminal type determine the target paging frame corresponding to the terminal.

The initial paging frame is a wireless paging frame determined by the terminal according to an existing protocol, and is usually represented by a system frame number (System Frame Number, SFN for short).

The target paging frame corresponding to the terminal is determined according to the initial paging frame corresponding to the terminal and the terminal type of the terminal. Optionally, a mapping relationship between the target paging frame, the initial paging frame and the terminal type can be established ( Such as a mapping table, etc.), so that the terminal, the base station, and the network side can determine the target paging frame corresponding to the terminal according to the mapping relationship.

Optionally, the determining the target paging frame corresponding to the terminal according to the initial paging frame and the terminal type includes: determining the target paging frame by using the following formula (1):

SFN'=(Ncate×SFN+Cate _index )mod{Ncate×floor[max(SFN)/Ncate]} (1)

Wherein, SFN' is the target paging frame, Ncate is the total number of terminal types supported on the current paging resource, Cate _index is the index of the terminal type, and SFN is the initial paging frame.

mod() means taking the remainder of the values in the brackets, floor() means rounding down the values in the brackets, and max() means taking the maximum value of the values in the brackets. Optionally, max(SFN) is the total number of SFNs, that is, 1024.

Optionally, the SFN can be determined according to the following formula (2):

SFN mod T=(T div N)×(UE_ID mod N) (2)

Among them, T is the DRX cycle of the terminal (also called UE), N=min(T, nB), div is the integer division operation, UE_ID is the identification number (Identify, ID for short) of the terminal identification, UE_ID=IMSI mod 1024N, and IMSI is Abbreviation for International Mobile Subscriber Identity (International Mobile Subscriber Identity), nB is the number of paging occasions in the paging radio frame.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of a corresponding relationship between a target paging frame and an initial paging frame provided by an embodiment of the present invention. Terminal types are divided according to coverage levels (CE Levels). The terminal types include three types: Corresponding to Level 0 (also known as CE Level 0), Level 1 (also known as CE Level 1) and Level 2 (CE Level 2). The radio frame numbers of the initial paging frame (SFN) are represented by SF#0, SF#1...SF#1022, SF#1023, and each initial paging frame corresponds to the respective target paging frame (SFN') of the three terminal types For example, when the SFN is SF#0, if the terminal type of the terminal corresponds to level 0, the radio frame number of the SFN' of the terminal is SF#0; when the SFN is SF#1, if the terminal type of the terminal corresponds to the level 1, the radio frame number of the SFN' of the terminal is SF#1; when the SFN is SF#2, if the terminal type of the terminal corresponds to level 2, the radio frame number of the SFN' of the terminal is SF#2; And so on.

It should be noted that the manner in which the terminal determines the initial paging frame includes, but is not limited to, the method in formula (1), and other methods in the prior art may also be used.
