Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a paging method, a paging device, and a computer-readable storage medium.
Background
In the Paging scheme in the prior art, a terminal cannot predict whether a Paging resource location has its own Paging message, and therefore, it is required to attempt to receive and decode a control signaling corresponding to the Paging message at all Paging Occasions (PO) corresponding to the terminal, for example, an NB-IoT terminal of a narrowband internet of things (NB-IoT), and usually monitors on a narrowband physical downlink control channel (NPDCCH channel). To further reduce the power consumption of the terminal, NB-IoT is currently studying a scheme for paging signaling in release R15.
The definition of the light paging signal is: a wake-up user, sent prior to the paging message, listens to the paging message for signals, which may have a synchronization function (referred to herein as a light paging signal). This light paging Signal includes, but is not limited to, a Wake Up Signal (WUS). One embodiment of the light paging signal may indicate whether a paging message exists on a corresponding paging resource location (e.g., PO) of the terminal by introducing the WUS, and if so, the terminal needs to decode a subsequent paging message control signaling, and if not, the terminal does not perform any operation, i.e., may still remain in an original state, such as a Power Saving Mode (PSM) state, an extended discontinuous reception (eDRX) state, or an idle state (idle). The WUS implementation complexity is lower than that of paging messages, the number of times of repetition is less, and the terminal is easier to decode, so that the power consumption of paging monitoring can be reduced to a certain extent.
The light paging signal scheme can ensure that the terminal does not influence the real-time performance of the downlink message, and reduce the frequency of monitoring the downlink paging message by the terminal, thereby achieving the purpose of reducing the standby power consumption. Currently, a specific implementation for a light paging signal scheme is under discussion, and therefore, a light paging signal scheme capable of effectively reducing power consumption of a terminal is required.

In one possible paging signal scheme, a terminal identifier group (UE _ ID group) is carried in a paging signal, different terminal identifier groups correspond to different paging signal resource locations, and terminals monitor the paging signal at the paging signal resource location corresponding to the terminal identifier group to which the terminal belongs.
For example, a grouping manner of a terminal identifier group may be the same as a Paging Occasion (PO) calculation manner of paging, that is, terminals located in the same PO belong to the same UE _ ID group, and the specific formula is as follows:
PO:i_s＝floor(UE_ID/N)mod Ns
wherein:
n represents the number of paging frames in a paging cycle, and the value is min (T, nB);
ns represents a paging opportunity contained in a paging frame, and the value is max (1, nB/T);
the UE _ ID value is IMSI mod 4096, wherein the IMSI is the international mobile subscriber identity of the terminal;
t { rf128, rf256, rf512, rf1024}, where rf128 denotes 128 radio frames;
nB＝{4T,2T,T,T/2,T/4,T/8,T/16,T/32,T/64,T/128,T/256,T/512,and T/1024}。
in the above-described light paging signal scheme, only the terminal identification (UE _ ID) is considered when performing terminal grouping. When a paged terminal is located at the edge of a cell (assuming that the coverage enhancement level of the terminal is 2), in order to ensure the receiving performance of the terminal located at the edge of the cell on a light paging signal (such as a WUS), the light paging signal needs to be transmitted by a larger number of times of repetition, so that terminals (such as terminals with coverage enhancement levels of 0 and 1 except the coverage enhancement level 2) receiving the light paging signal at the same light paging signal resource position can be awakened to monitor a paging message, thereby causing unnecessary power consumption of the terminals.
In view of the above problems, embodiments of the present invention provide a paging method, which can reduce power consumption of a terminal in a light paging signal process. Fig. 1 is a flowchart illustrating a paging method applied to a network device according to an embodiment of the present invention. Here, the network side device may specifically be a base station, and the base station will be described as an example below. As shown in fig. 1, the paging method includes:
Here, the coverage enhancement level information of the terminal to be paged is explicitly carried, and specifically, the coverage enhancement level information may be carried in a predetermined field in the first paging signal. For NB-IoT systems, coverage enhancement level information carrying 2 bits in the WUS can be considered, and a specific indication is shown in table 1:
TABLE 1
Implicitly carried, the coverage enhancement level information can be indicated by a sequence employed by the first paging signal. For example, different sequences are preset to correspond to different coverage enhancement level information, and then the coverage enhancement level information implicitly carried by the first light paging signal can be obtained according to the coverage enhancement level information corresponding to the sequence adopted by the first light paging signal.
Through the above steps, the embodiment of the present invention carries the coverage enhancement level information of the terminal to be paged in the first light paging signal, so that the terminal that does not match the coverage enhancement level information carried in the first light paging signal (for example, the terminal to be paged belongs to the same terminal identification group but has a different coverage enhancement level) can monitor the subsequent paging message without waking up, and the power consumption of the terminals can be reduced.
Considering that the number of terminals to be paged may be greater than 1, at this time, another paging method according to an embodiment of the present invention may include the following steps:
step S1, obtaining the coverage enhancement grade information of the terminal to be paged
Here, the Coverage Enhancement Level (CE Level) information reflects a requirement of Coverage Enhancement of the terminal. The terminal can select a threshold information list according to a preset physical random access channel and judge the coverage enhancement level of the terminal. For example, if the received power (RSRP) of the reference signal at the network side by the terminal is less than a threshold corresponding to the coverage enhancement level N configured in the preset physical random access channel selection threshold information list, and the terminal supports the coverage enhancement level N, the coverage enhancement level at the terminal is considered to be N. For example, the following steps are carried out: assuming that the coverage enhancement Level takes a value from 0 to 2, namely CE Level is divided into three levels, if the physical random access channel selection threshold information list of one cell is (-112dBm, -122dBm), when the RSRP measured by the terminal is > -112dBm, the terminal is in the coverage enhancement Level 0; when the RSRP is less than or equal to-112 dBm and is less than-122 dBm measured by the terminal, the terminal is in a coverage enhancement level 1; when the terminal measures RSRP ≦ -122dBm, the terminal is at coverage enhancement level 2.
In general, the base station may select the corresponding number of information retransmissions, such as the number of transmissions of the paging signal, according to the CE Level of the terminal. Specifically, the base station may obtain coverage enhancement level information of the terminal to be paged from a Mobility Management Entity (MME) through an S1 interface, or the base station may locally maintain the coverage enhancement level information of the terminal in a random access process, and further obtain the coverage enhancement level information of the terminal to be paged according to the locally maintained coverage enhancement level information of the terminal to be paged in a latest random access process.
Step S2, if the terminal to be paged only includes one terminal, or includes at least two terminals with the same coverage enhancement level information, then a first light paging signal is sent at a light paging signal resource location corresponding to the terminal to be paged, where the first light paging signal explicitly or implicitly carries the coverage enhancement level information of the terminal to be paged.
Here, the terminals to be paged may include one or at least 2. When the terminal to be paged only includes one terminal, or the coverage enhancement level information of each terminal in the terminal to be paged is the same, the embodiment of the present invention sends the first paging signal.
In the embodiment of the present invention, if the terminal to be paged includes terminals with different coverage enhancement level information, that is, there are at least two different types of coverage enhancement level information in the coverage enhancement level information of the terminal to be paged, at this time, the base station sends a second light paging signal at a light paging signal resource location corresponding to the terminal to be paged, where the second light paging signal does not carry the coverage enhancement level information of the terminal to be paged.
Here, the location of the light paging signal resource corresponding to the terminal to be paged may be determined based on the terminal identification group (UE _ ID group). Generally, different terminal identifier groups correspond to different locations of the light paging signal resource, and the terminals monitor the light paging signal at the locations of the light paging signal resource corresponding to the respective terminal identifier groups. In the embodiment of the invention, the first light paging signal carries the coverage enhancement level information of the terminal to be paged explicitly or implicitly, so that the terminal in the first light paging signal is monitored, and the subsequent paging message is monitored only when the coverage enhancement level information of the terminal is matched with the coverage enhancement level information carried in the first light paging signal, if the terminal is in a PSM/eDRX/idle state currently, the terminal needs to be awakened first, and then the paging message is monitored; if the two coverage enhancement level information do not match, the terminal abandons monitoring subsequent paging messages, and at this time, the terminal may maintain the current state of the terminal (e.g., PSM/eDRX/idle state) unchanged.
In step S2, the base station may determine resource scheduling information used by the first light paging signal according to the coverage enhancement level information of the terminal to be paged, where the resource scheduling information includes a number of repeated transmissions and/or a Modulation and Coding Scheme (MCS), and then transmit the first light paging signal at a light paging signal resource position corresponding to the terminal to be paged according to the resource scheduling information used by the first light paging signal. For example, the first paging signal is repeatedly transmitted according to the number of repeated transmissions.
After step S2, the base station may further send a paging message for the terminal to be paged in a paging resource location (e.g., paging occasion PO) corresponding to the terminal to be paged, so as to page the terminal to be paged.
In the paging method of the embodiment of the present invention, in step S1, if it fails to acquire the coverage enhancement level information of the terminal to be paged (for example, the coverage enhancement level information of the terminal to be paged is not acquired from an MME, or the base station does not locally maintain the coverage enhancement level information of the terminal to be paged, etc.), or a non-first paging for the terminal to be paged is initiated, the base station may further send a second light paging signal on a light paging signal resource location corresponding to the terminal to be paged, where the second light paging signal is different from the first light paging signal and does not carry the coverage enhancement level information of the terminal to be paged, so as to improve a paging success rate. Here, the non-first paging may include a paging after the first paging fails, and specifically, may include a second paging, a third paging, a greater number of times of paging, and the like after the first paging. The specific maximum number of pages may have different values depending on different network configurations. The reason for the paging failure is various, for example, the terminal to be paged may move, move out of the previous cell, and the like.
As one implementation, the paging range of the second paging signal may be the same as the paging range of the first paging signal, e.g., the first paging signal and the second paging signal are transmitted in the same cell. In order to improve the paging success rate, the paging range of the second paging signal may also be larger than the paging range of the first paging signal, for example, compared to the first paging signal, the embodiment of the present invention transmits the second paging signal in more cells. Of course, the second paging signal may be sent in the same paging range as the first paging signal and the paging message may be sent in the PO corresponding to the terminal to be paged, and if the paging fails, the second paging signal may be further sent in a larger range, for example, the second paging signal may be sent in a cell list of a Tracking Area (TA) list of the terminal to be paged.
In addition, when sending the second paging signal, the embodiment of the present invention may determine resource scheduling information adopted by the second paging signal according to the maximum coverage enhancement level information of the cell where the terminal to be paged resides, wherein the resource scheduling information includes a number of repeated transmissions and/or a Modulation and Coding Scheme (MCS); and then, according to the resource scheduling information adopted by the second light paging signal, sending the second light paging signal at the light paging signal resource position corresponding to the terminal to be paged. For example, the coverage enhancement level information of the cell includes 0 and 1, and the resource scheduling information, e.g., the number of repeated transmissions, may be determined according to the maximum value (i.e., 1) thereof. In general, the number of repeated transmissions is positively correlated with the coverage enhancement level information, and the MCS is negatively correlated with the coverage enhancement level information. Namely, the larger the coverage enhancement level information is, the larger the corresponding repeated transmission times are; the larger the coverage enhancement level information is, the smaller the value of the corresponding MCS is. Here, the embodiment of the present invention determines the resource scheduling information according to the maximum coverage enhancement level information of the cell, and compared with a method of directly determining the resource scheduling information according to the maximum value of the coverage enhancement level information (for example, in some scenarios, the maximum value of the coverage enhancement level information is 2), the embodiment of the present invention can reduce resource overhead caused by repeated transmission, MCS, and the like.
The paging method according to the embodiment of the present invention is explained above from the base station side, and is further explained below from the terminal side. Referring to fig. 2, a paging method according to an embodiment of the present invention, when applied to a terminal side, includes:
and step 21, monitoring a first paging signal sent by a network on a paging signal resource position corresponding to the terminal, wherein the first paging signal explicitly or implicitly carries coverage enhancement level information of the terminal to be paged.
Here, the terminal monitors the light paging signal at the light paging signal resource position corresponding to the terminal identification group to which the terminal belongs, and if the light paging signal is monitored, the terminal tries to acquire the coverage enhancement level information of the terminal to be paged carried in the light paging signal resource position. The light paging signal that carries the coverage enhancement level information explicitly or implicitly is referred to herein as the first light paging signal. For example, for explicit carry, the terminal may extract the coverage enhancement level information from a predetermined field of the first light paging signal; for implicit carry, the terminal may obtain the coverage enhancement level information implicitly carried by the first paging signal according to the coverage enhancement level information corresponding to the sequence adopted by the first paging signal.
And step 22, when the coverage enhancement level information of the terminal is matched with the coverage enhancement level information carried by the first light paging signal, continuously monitoring the paging message sent by the network at the paging resource position corresponding to the terminal.
Here, the terminal compares the coverage enhancement level information carried by the first paging signal with its own coverage enhancement level information, and if the coverage enhancement level information is matched with the coverage enhancement level information, the terminal continues to monitor a paging message sent by a subsequent network at a paging resource location (such as a paging occasion PO) corresponding to the terminal; if not, the terminal does not need to monitor the subsequent paging message, at this time, the terminal ignores the first paging signal and maintains the state of the terminal as the state before monitoring the first paging signal, for example, the state of the terminal before monitoring the first paging signal is the PSM/eDRX/idle state, and at this time, the state of the terminal continues to be maintained in the PSM/eDRX/idle state.
Because the network may also send a second paging signal that does not carry coverage enhancement level information of the terminal to be paged, if the terminal monitors the second paging signal sent by the network at a corresponding paging signal resource location, it may continue to monitor a paging message sent by a subsequent network at a paging resource location (e.g., paging occasion PO) corresponding to the terminal.
Of course, in the embodiment of the present invention, if the terminal does not monitor any paging signal in the paging signal resource location corresponding to the terminal, the terminal will abandon to continue monitoring the paging message subsequently sent by the network, and maintain the state of the terminal as the state before the monitoring action, for example, if the state before the monitoring is the PSM/eDRX/idle state, the state of the terminal will continue to be maintained in the PSM/eDRX/idle state at this time.
Through the steps, the terminal monitors the subsequent paging message only when the coverage enhancement level carried by the terminal is matched with the terminal after receiving the first light paging signal, so that the awakening times of the terminal can be reduced, and the power consumption of the terminal can be reduced.
Fig. 3 shows an example of a paging method provided by the embodiment of the present invention, and fig. 4 shows a comparative example of a paging method not adopting the embodiment of the present invention. It can be seen that, after the paging method of the embodiment of the present invention is adopted, the number of terminals which need to be awakened is reduced, and thus the power consumption of the terminals can be reduced.
Based on the method, the embodiment of the invention also provides equipment for implementing the method.
