Description

Paging method, terminal and base station

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a paging method, a terminal, and a base station.

Background

In a Long Term Evolution (LTE) system, a network side device may send a page (paging) to a terminal (UE) in an IDLE state (RRC _ IDLE) and a connected state (RRC _ CONNECTION). The paging procedure may be triggered by the core network equipment or by the base station (eNodeB). The specific process is as follows: a Mobile Management Entity (MME) initiates a Paging process to each base station by using Paging messages (Paging), wherein each Paging message carries the information of a paged UE; after receiving paging messages of MME, a base station assembles paging of UE with the same paging time (PO) into a paging message, and transmits the paging message to related UE through a paging channel, and the UE calculates paging time (including Paging Frame (PF) and paging time (PO, paging subframe)) according to the following formula by combining paging parameters received by the UE through system messages and an International Mobile Subscriber Identity (IMSI) of the UE so as to receive the paging message at corresponding time:

PF：SFN mod T＝(T div N)*(UE_ID mod N)

PO：i_s＝floor(UE_ID/N)mod Ns；

Where SFN indicates a system frame number, mod indicates modulo operation, T indicates a paging cycle, div indicates division operation, UE _ ID indicates a terminal identifier, i _ s indicates an index of a paging time, floor indicates rounding-down operation, Ns ═ max (1, nB/T), N ═ min (T, nB), and nB indicates the density of POs.

However, in New Radio (NR), the paging terminals may be terminals in different states (idle or inactive states), terminals performing different types of services, terminals having different attributes, and the like, and different operators may have different deployment requirements, so that a certain binding relationship may exist between a paging message and a Synchronization Signal and/or Physical Broadcast Channel Block (SS/PBCH Block), and therefore, if a formula is used to calculate a paging occasion in a similar long term evolution system, a time corresponding to the calculated paging occasion may not be suitable for receiving the paging message.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Currently, a New Radio (NR) paging mechanism is in a 3GPP conference discussion, and there are conclusions related to paging:

1. configuring an association relationship between a Physical Downlink Control Channel (PDCCH) monitoring window containing paging (paging) Downlink Control Information (DCI) and an actually transmitted Synchronization Signal and/or Physical Broadcast Channel Block (SS/PBCH Block for short) for the Remaining minimum System message (RMSI);

2. the default association relationship between the PDCCH monitoring window (paging monitoring window) containing the paging DCI and the actually transmitted SS/PBCH BLOCK is the association relationship between the SS/PBCH BLOCK and the RMSI monitoring window;

3. at least the mode that Paging DCI is followed by Paging message (Paging message) needs to be supported, and other modes are not supported temporarily in R-15;

the length of the PO is the time of beam scanning (beam) and it is assumed that the same Paging message (Paging message) is sent once on all beams (beams);

PO can be time division multiplexed or frequency division multiplexed with SS/PBCH BLOCK;

PO calculation is based on terminal identification (UE ID) and a concept similar to reference frames in LTE.

There are two modes of PO/PF calculation tentative: mode 1: default association between pdcch monitoring window containing paging DCI and actually transmitted SS/PBCH BLOCK, mode 2: non-default association.

a) Wherein for mode 1, the calculation formula is as follows:

PF：(SFN+offset)mod T＝(T div N)*(UE_ID mod N)，

PO is determined by i _ s: i _ s ═ floor (UE _ ID/N) mod Ns; where Ns ═ max (1, nB/T), in which mode Ns can only be 1 or 2, if Ns ═ 1, it means that there is only one PO in the frame indicated by the calculated PF; if Ns is 2, it indicates that there are two POs in the frame indicated by PF, where when i _ s is 0, the PO is located in the first half of the frame, and when i _ s is 1, the PO is located in the second half of the frame.

b) For mode 2, the calculation formula is as follows:

PF：SFN mod T＝(T div N)*(UE_ID mod N)

PO: i _ s ═ floor (UE _ ID/N) mod Ns; wherein Ns ═ max (1, nB/T);

for _ s is 0, the UE detects 1st PO; i _ s is 1, the UE detects 2nd PO; i _ s is 2, the UE detects 3rd PO; i _ s is 3, the UE detects 4th PO.

Defined according to the paging-search space (paging-SearchSpace):

-1st PO is the first round of beam scanning;

-2nd PO is the second round of beam scanning;

-3rd PO is the third beam sweep;

-4thPO is the fourth beam sweep.

In addition, according to the conclusion of the existing protocol, the binding relationship between the SS/PBCH BLOCK and the PO in the default association may cause the situations of limited paging capacity, waste of resources and the like, and the non-default association may also have the problem of conflict with other configurations, so that a new binding relationship may appear in the future or the binding relationship is not used, so as to alleviate the problem.

Referring to fig. 1, fig. 1 is a flowchart illustrating a paging method according to an embodiment of the present invention, where the method is applied to a terminal and includes the following steps:

step 11: determining a currently used paging mode, wherein the currently used paging mode is one of at least two selectable paging modes, and formulas for calculating paging occasions are different among different paging modes;

step 12: calculating the paging time according to the formula for calculating the paging time corresponding to the determined currently used paging mode;

step 13: receiving a paging message at a time corresponding to the paging occasion.

The paging method provided by the embodiment of the invention is suitable for NR, and different paging modes can be used for terminals in different conditions, such as terminals in different states, terminals executing different services or terminals with different attributes, so that various terminals can receive paging messages at proper time.

The above paging method is exemplified below.

As one of the optional specific embodiments: before the step of determining the currently used paging mode (i.e. step 11), the method further includes:

and receiving mode indication information sent by a base station, wherein the mode indication information is used for selecting a paging mode for the terminal as the currently used paging mode.

In the embodiment of the invention, the terminal can directly determine the currently used paging mode according to the indication or the configuration (mode indication information) of the base station.

In addition, before receiving the mode indication information sent by the base station, the terminal may also send relevant information of the terminal to the base station, so that the base station selects a paging mode for the terminal according to the relevant information of the terminal, where the relevant information of the terminal includes at least one of: capability information of the terminal, paging mode preferences, and a type of service to be performed. For example, if the terminal is initially accessed to the network, the terminal may first send its paging mode preference to the base station in MSG3(Message 3, which is an RRC Connection Request Message or an RRC reestablishment Request Message sent by the terminal to the base station), and the base station may directly select a paging mode currently used by the terminal according to the paging mode preference of the terminal and then notify the terminal through the mode indication information. Or, the base station refuses to configure the paging mode corresponding to the paging mode preference of the terminal as the paging mode currently used by the terminal, and sends other paging modes selected by the base station itself (which may be selected according to the capability of the terminal) to the terminal through the mode indication information. In addition, if the terminal is in the connected state or the inactive state, it may feedback the type of service and/or preference that the terminal is likely to perform subsequently to the base station (network) in the last data transmission to change its paging mode, so that the base station will consider the type of service and/or preference (of paging mode) that the terminal is likely to perform when configuring (selecting) the paging mode for the terminal next time.

Specifically, referring to fig. 2, the mode indication information may be carried by a system message broadcast by the base station, and specifically may be carried by an indication bit added in the system message.

Wherein the mode indication information carried by the system message broadcast by the base station includes: the terminals meeting preset conditions use the same paging mode, and the preset conditions comprise at least one of the following conditions:

terminals located in the cell corresponding to the base station, that is, the cell corresponding to the base station, use a paging mode in a unified manner;

within a preset period range and in a cell corresponding to the base station, that is, within a specified period range, all terminals in the cell corresponding to the base station use a certain paging mode, and at other times except the specified period, terminals in the cell corresponding to the base station may use other paging modes;

the method comprises the steps that a preset identifier is included, and a specific base station can appoint that terminals with ID (Identity, Identity identification number) in a certain range all use a certain paging mode;

in a preset state, the preset state includes at least one of: an idle state (idle state), an inactive state (inactive state) and a connected state (connected state), that is, the base station can designate terminals in different states to respectively use different paging modes;

Executing a preset service, that is, configuring different paging modes for different service terminals, for example, all IoT (Internet of things) terminals may be specified to use a certain paging mode;

the preset version, for example, the terminal configuring the R15(Release 15) version and the terminal of the R16 version, respectively use different paging modes.

In the embodiment of the invention, the terminals which simultaneously meet the two or more preset conditions can be appointed to use the same paging mode. For example, a terminal of version R15 in an idle state may be configured to use one paging mode and a terminal of version R15 in a connected state may be configured to use another paging mode.

In the embodiment of the invention, the base station can assign the corresponding paging mode to each terminal or various types of terminals in a broadcasting mode. In other embodiments of the present invention, the mode indication information sent by the base station may also be carried by a dedicated signaling sent by the base station to the terminal, and specifically may be carried by an indication bit added in the dedicated signaling, that is, the base station may configure a paging mode for each terminal through the dedicated signaling.

Wherein the dedicated signaling comprises at least one of: RRC connection setup message, RRC reconfiguration message, and RRC connection release message.

Specifically, referring to fig. 3 and 4, when the terminal initially accesses the network, the base station may notify the terminal of the currently used paging mode designated for the terminal through an RRC connection setup message or an RRC reconfiguration message, and the terminal may monitor the paging message according to the currently used paging mode after completing the attach procedure and entering the idle state. Or, when the terminal performs state transition, the base station may notify the terminal of a paging mode used subsequently through an RRC connection release message, and the terminal may monitor the paging message according to the paging mode, with the paging mode being used as a currently used paging mode in a subsequent process.

After the currently used paging mode is determined according to the mode indication information sent by the base station, the paging occasion needs to be calculated according to the formula for calculating the paging occasion corresponding to the determined paging mode. The formula for calculating the paging occasion corresponding to the paging mode may be pre-stored in the terminal, for example, may be pre-stored when the terminal leaves a factory; or, the base station issues the paging mode in advance through the system message, that is, the base station may first inform the terminal of which paging modes exist through the system message, and then inform the terminal of which paging mode is currently used through the mode indication information; or, the mode indication information includes a formula for calculating the paging occasion corresponding to the currently used paging mode.

In addition, when the paging occasion is calculated according to the formula for calculating the paging occasion corresponding to the determined paging mode, the corresponding paging occasion can be calculated only by acquiring related paging parameters. In the embodiment of the present invention, the paging parameter may be issued by the base station, so the paging method further includes:

receiving paging parameters corresponding to a paging mode sent by a base station, wherein the paging parameters comprise at least one of the following: paging cycle, SS/PBCH BLOCK cycle, and association pattern of different paging monitoring windows with SS/PBCH BLOCK.

Specifically, the base station may issue paging parameters corresponding to each paging mode before the step of determining the currently used paging mode by the terminal, for example, when the terminal is informed of which paging modes are available through a system message, the paging parameters corresponding to the paging modes are issued. The base station can also issue the paging parameters corresponding to the paging mode after the terminal determines the currently used paging mode, and at the moment, the base station can only issue the paging parameters corresponding to the currently used paging mode determined by the terminal, so that the waste of communication resources and the storage space required by the terminal for storing the paging parameters are reduced.

In the embodiment of the present invention, if the formula for calculating the paging occasion corresponding to the currently used paging mode is not issued to the terminal together with the mode indication information, but is pre-stored in the terminal or issued by the base station through the system message in advance, after the currently used paging mode is determined, the terminal needs to obtain the formula for calculating the paging occasion corresponding to the currently used paging mode by internally reading or re-reading the system message issued by the base station in advance. Then, the paging occasions (PO and PF) are calculated according to the corresponding paging parameters issued by the base station.

In this embodiment of the present invention, the formula for calculating the paging occasion corresponding to the paging mode is one of the following formulas (different paging modes correspond to different formulas for calculating the paging occasion):

PF:SFN mod T＝(T div N)*(UE_ID mod N)，PO：i_s＝floor(UE_ID/N)mod Ns，

indicates the total number of slots in a frame, and offset indicates the interval between two adjacent POs in a paging cycle;

PF：(SFN+offset)mod T＝(T div N)*(UE_ID mod N)，

PO：i_s＝floor(UE_ID/N)mod Ns，

wherein, SFN represents a system frame number, offset represents an interval between two adjacent POs in one paging cycle, offset is an integer, when nB is T/2, offset may take 0 or 1, when nB is T/4, offset may take 0 or 1 or 2 or 3, when nB is T/8, offset may take any integer of 0-7 (including 0 and 7), when nB is T/16, offset may take any integer of 0-15 (including 0 and 15), mod represents modulo operation, T represents a paging cycle, div represents division operation, N is min (T, nB), nB represents a density of POs, UE _ ID represents a terminal identifier, i _ s represents an index of a paging time, floor represents rounding-down operation, and Ns is max (1, nB/T);

and μ is defined in protocol 38.213.

The second embodiment of the present invention provides another paging method, which is applied to a terminal, and is different from the first embodiment in that: and the mode indication information is sent by the base station and used for selecting one paging mode for the terminal as the currently used paging mode, or used for selecting at least two paging modes for the terminal to select one paging mode from the paging modes as the currently used paging mode. And, when only one paging mode is included in the mode indication information, the terminal does not agree to adopt the paging mode as a currently used paging mode.

When the mode indication information is carried by the system message broadcasted by the base station, the terminal obtains one or more paging modes indicated by the base station. When the mode indication information is sent to the terminal by the base station through dedicated signaling, the terminal obtains a paging mode indicated by the base station.

Optionally, after the step of receiving the mode indication information sent by the base station, the method further includes:

When the mode indication information is carried by the system message broadcast by the base station, if the terminal is initially accessed to the network, the terminal may feed back its capability information and/or paging mode preference in MSG3 or MSG5 to select one paging mode in the mode indication information as a currently used paging mode or select other paging modes other than the paging mode in the mode indication information as the currently used paging mode. The MSG3(Message 3) is an RRC Connection Request (RRC Connection Request) Message or an RRC reestablishment Request Message transmitted by the terminal to the base station, and the MSG5(Message 5) is an RRC Connection Setup Complete (RRC Connection Setup Complete) Message or an RRC reestablishment Complete Message transmitted by the terminal to the base station.

When the mode indication information sent by the base station is carried by the dedicated signaling sent by the base station to the terminal, the terminal may send its own paging mode preference and/or capability information to the base station in MSG3 or MSG 5.

In the embodiment of the present invention, the terminal needs to select one of at least two paging modes indicated in the mode indication information as a currently used paging mode in consideration of its own capability, a service to be performed, and the like. Or, when the terminal does not agree to use the paging mode in the mode indication information sent by the base station as the currently used paging mode, the terminal may negotiate with the base station to select another more suitable paging mode as the currently used paging mode. When the base station selects the paging mode for the terminal, if the terminal is not selected according to the relevant information of the terminal sent by the terminal or the terminal does not send the relevant information of the terminal to the base station, the situation that the terminal does not adopt the paging mode selected by the base station may occur.

Specifically, referring to fig. 5, in an embodiment, after the step of sending the information related to the terminal to the base station, the method further includes:

In this embodiment, the terminal may send the paging mode preference to the base station to negotiate with the base station to adopt the paging mode corresponding to the paging mode preference as the currently used paging mode. And if the base station agrees, sending confirmation information to the terminal to confirm that the paging mode corresponding to the paging mode preference is taken as the currently used paging mode. The terminal can also send the capability information of the terminal to negotiate the currently used paging mode with the base station, and after receiving the capability information fed back by the terminal, the base station can directly adapt a proper paging mode to the terminal according to the capability information of the terminal and send confirmation information to the terminal.

Further, after the step of receiving the acknowledgement information sent by the base station, the method further includes:

In the embodiment of the invention, if the formula for calculating the paging occasion corresponding to each paging mode is not prestored in the terminal, the formula for calculating the paging occasion corresponding to each paging mode is not issued by the base station through the system message in advance, and only the formula for calculating the paging occasion corresponding to the paging mode in the mode indication information is issued, the base station needs to issue the formula for calculating the paging occasion corresponding to the finally determined paging mode. In addition, if the base station does not issue the paging parameters corresponding to each paging mode before, but only issues the paging parameters corresponding to the paging mode in the mode indication information, the base station needs to re-issue the paging parameters corresponding to the finally determined paging mode.

In another embodiment, after the step of sending the information related to the terminal to the base station, the method further includes:

receiving feedback information sent by the base station, wherein the feedback information is used for informing the terminal of refusing to take a paging mode corresponding to the paging mode preference of the terminal as a paging mode currently used by the terminal, and the feedback information can be sent through a special signaling;

In the embodiment of the present invention, if the base station does not agree with the paging mode proposed by the terminal as the currently used paging mode, specifically, it may disagree with the paging mode corresponding to the preference of the paging mode of the terminal as the currently used paging mode, then send feedback information to the terminal to notify the terminal that the change of the paging mode is failed, and may carry a reason (cause value), for example, a large false-wake probability may be brought about due to an excessive number of terminals in the paging mode. In addition, the base station may send the terminal other, possibly suitable, paging modes for selection by the terminal or may directly select another paging mode for the terminal.

Similarly, if there is no formula and/or paging parameter for calculating the paging occasion corresponding to the other paging modes selected by the base station in the terminal, the base station needs to additionally issue the paging occasion to the terminal. The method comprises the following specific steps:

after the step of receiving another paging mode selected by the base station for the terminal, the method further includes:

receiving a formula and/or paging parameters for calculating paging occasions corresponding to the other paging modes, which are sent by the base station; alternatively, the first and second electrodes may be,

after the step of receiving at least two other paging modes selected by the base station for the terminal, the method further includes:

In the embodiment of the invention, after one or more rounds of negotiation with the base station, the terminal confirms the currently used paging mode, and after a formula for calculating the paging occasion corresponding to the paging mode is obtained through internal reading (prestored in the terminal), or re-reading of a certain system message (previously issued by the base station) or re-issued by the base station, the paging occasion is calculated according to other paging parameters configured by the network.

The method further comprises the following steps:

Sending paging parameters corresponding to a paging mode to the terminal, wherein the paging parameters comprise at least one of the following: paging cycle, SS/PBCH BLOCK cycle, and association pattern of different paging monitoring windows with SS/PBCH BLOCK.

In the embodiment of the invention, after the base station sends at least two other paging modes selected for the terminal to the terminal, the base station can start a timer to ensure that the terminal completes the selection within a certain time, and if the terminal does not complete the selection after time out, the base station can directly designate one of the at least two other paging modes as the currently used paging mode.

In addition, after the base station sends the at least two other paging modes selected for the terminal to the terminal, the base station may not receive a reply message of the terminal for some reason (for example, poor channel quality), and if a certain time is exceeded, the base station considers that the negotiation fails, and then sends the message for allowing the terminal to select again. Therefore, the base station may also start a counter to ensure that the terminal completes the selection of the paging mode within a certain number of times. If the number of times exceeds the set number, the base station may also directly designate one of the at least two other paging modes as the currently used paging mode.
