Description

Paging method, device, equipment and storage medium based on enhanced discontinuous reception

Technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to a paging method, device, device, and storage medium based on enhanced discontinuous reception.

Background technique

3GPP (3rd Generation Partnership Project) has introduced a paging mechanism in 5G (5th-Generation) NR (New Radio).

The main functions of the paging mechanism include two aspects. On the one hand, when the terminal device is in the RRC (Radio Resource Control) IDLE (idle state) or RRC INACTIVE (inactive state), the network device can page the terminal device through the paging message (Paging Message). . On the other hand, the network equipment is made to notify the terminal equipment of system message changes or earthquake, tsunami and other public warning information through short messages. At this time, the paging mechanism is applicable to all RRC states of the terminal equipment, including the connected state. For the terminal equipment in the idle or inactive state, since there is no other data communication between the terminal equipment and the network equipment, based on the consideration of power saving of the terminal equipment, the terminal equipment can monitor the paging channel non-continuously, that is, adopt discontinuous reception Paging (Paging DRX (Discontinuous Reception)) mechanism. Under the discontinuous reception paging mechanism, the terminal device only needs to monitor the paging message during one PO (Paging Occasion, paging occasion) in each DRX cycle.

However, for low-capacity terminal devices, even if a discontinuous receiving paging mechanism is used to monitor paging messages, problems such as higher processing overhead, faster power consumption, and shorter battery life will occur. Therefore, for terminal devices in an idle state or in an inactive state, further discussion and research is needed on how to save power.

The network architecture and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that with the network architecture The evolution of and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

Please refer to FIG. 1, which shows a schematic diagram of a system architecture provided by an embodiment of the present application. The system architecture 100 may include: a terminal device 10, an access network device 20, and a core network device 30.

The terminal device 10 may refer to a UE, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, the terminal device can also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop, wireless local loop) station, a PDA (Personal Digita1 Assistant, personal digital processing), Handheld devices with wireless communication functions, computing devices, or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5GS or future evolution of PLMN (Pub1ic Land Mobi1e Network, public land mobile communication network) This is not limited in this embodiment of the present application. For ease of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 may be distributed in a cell managed by each access network device 20.

The access network device 20 is a device deployed in the access network to provide the terminal device 10 with a wireless communication function. The access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in 5G NR systems, they are called gNodeB or gNB. With the evolution of communication technology, the name "access network equipment" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. Optionally, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network device 30. Exemplarily, in the LTE system, the access network device 20 may be EUTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in EUTRAN; in the 5G NR system, access The network equipment 20 may be a RAN (Radio Access Network, radio access network) or one or more gNBs in the RAN.

The function of the core network device 30 is mainly to provide user connections, manage users, and complete the bearing of services, as a bearer network to provide an interface to an external network. For example, the core network equipment in the 5G NR system may include AMF (Access and Mobility Management Function, access and mobility management function) entities, UPF (User Plane Function, user plane function) entities, and SMF (Session Management Function, session management). Function) physical and other equipment. In an example, the core network device 30 may configure related parameters for the terminal device 10, for example, configure the terminal device 10 with parameters related to the paging process, such as DRX configuration information.

In an example, the access network device 20 and the core network device 30 communicate with each other through a certain aerial technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other through a certain aerial technology, such as a Uu interface.

3GPP has introduced a paging mechanism in the 5G NR system. The main functions of the paging mechanism include two aspects. On the one hand, the network device can page the terminal device through a paging message when the terminal device is in an idle state or in an inactive state. On the other hand, the network equipment is made to notify the terminal equipment of system message changes or earthquake, tsunami and other public warning information through short messages. At this time, the paging mechanism is applicable to all RRC states of the terminal equipment, including the connected state.

In an example, the paging channel includes PDCCH (Physical Downlink Control Channel) scrambled by P-RNTI (Paging Radio Network Temporary Identifier), and PDSCH scheduled by the PDCCH (Physical Downlink Share Channel, physical downlink shared channel). Exemplarily, the above-mentioned paging message is transmitted in the PDSCH, and the above-mentioned short message occupies 8 bits and is transmitted in the PDCCH.

For the terminal equipment in the idle or inactive state, since there is no other data communication between the terminal equipment and the network equipment, based on the consideration of power saving of the terminal equipment, the terminal equipment can monitor the paging channel non-continuously, that is, the Paging DRX mechanism is adopted. . Under the Paging DRX mechanism, the terminal device only needs to monitor the paging message during one PO in each DRX cycle. In the embodiment of the present application, the PO includes a series of monitoring opportunities for the PDCCH. Optionally, the PO is composed of multiple time slots. In addition, in the Paging DRX mechanism, there is also the concept of PF (Paging Frame). PF refers to a radio frame (exemplarily, the radio frame is 10 milliseconds). Optionally, the radio frame includes At least one PO; or, the radio frame includes the start position of at least one PO.

In an example, the Paging DRX cycle (cycle) is determined by the public cycle in the system broadcast and the exclusive cycle configured in higher-level signaling (such as NAS signaling). Optionally, the terminal device takes the smallest cycle of the two It is paging DRX cycle. Exemplarily, one paging DRX cycle includes at least one PO, and the specific PO monitoring used by the terminal device is related to the identification of the terminal device. The following exemplarily shows how to determine the PF and PO of a terminal device in a paging DRX cycle:

The SFN (System Frame Number) number of PF is determined by the following formula:

(SFN+PF_offset) mod T=(T div N)*(UE_ID mod N)

Among them, T is the DRX cycle for the terminal device to receive paging. In an example, a network device will broadcast a default DRX cycle. If an RRC message or a high-level message (such as a NAS (Non Access Stratum, non-access stratum) message) configures its own DRX cycle for the terminal device, the terminal The device uses the smallest DRX cycle of the DRX cycle broadcast by the network device and the RRC message or high-level message (such as NAS message) as T; if the RRC message or high-level message (such as NAS message) does not configure its dedicated DRX cycle for the terminal device , The terminal device uses the DRX cycle broadcast by the network device as T. N is the number of PFs included in a DRX cycle. Ns is the number of PO contained in a PF. PF_offset is a time domain offset used to determine PF.

The Index (number) (i_s) where the PO is located in a PF is determined by the following formula:

i_s=floor(UE_ID/N)mod Ns

Among them, UE_ID is the remainder of the TMSI (Temporary Mobile Subscriber Identity, Temporary Mobile Subscriber Identity) of the terminal device divided by 1024.

For the terminal device, according to the above formula, the position of the PF and the Index of the PO in a paging DRX cycle can be determined. In an example, the PO is composed of at least one PDCCH monitoring occasion (monitoring occasion), and one PO includes X PDCCH monitoring occasions, where X is a positive integer, and X is equal to the SSB (Synchronization Signal Block) broadcast in the system message. Signal block) The actual number of transmissions. After the terminal device determines the position of the PF, the Index of the PO, and the number of PDCCH monitoring occurrences in the PO, it only needs to use the relevant configuration parameters to determine the starting position of the first PDCCH monitoring occurrence of the PO. The starting position can be passed by the higher layer. Signaling configuration, or obtained based on PO Index. After the terminal device determines the starting position, it can blindly check the paging message according to the determined PO.

In an example, the DRX cycle can be up to 256 SFNs. Considering that NB-IoT (Narrow Band Internet of Things, Narrowband Internet of Things) and eMTC (Enhanced Machine Type Communication) and other types of terminal equipment have a relatively single business type and low business volume activity. The terminal device is in a disconnected state most of the time. At the same time, considering that the services of these terminal devices are not sensitive to the delay requirements, in order to save power in the non-connected state, the LTE (Long Term Evolution) system introduces the eDRX mechanism for such terminal devices. A larger paging cycle can be supported, that is, the paging cycle can be greater than 256 SFNs.

For a terminal device configured with eDRX, for example, if the eDRX cycle of the terminal device is 512 SFNs, the terminal device calculates the corresponding PO based on T=512. If the eDRX cycle of the terminal device is greater than or equal to 1 H-SFN (Hyper System Frame Number), the terminal device has a corresponding PTW (Paging Time Window) within an eDRX cycle The PDCCH scrambled by the P-RNTI is monitored on the PO. Among them, PTW is the exclusive time window for terminal equipment. Exemplarily, PTW is based on PH (Paging H-SFN, paging superframe), a start time point PTW_start (paging time window start radio frame) and an end time point PTW_end (paging time The window terminates the radio frame) is determined. The following exemplarily shows how to determine PTW related parameters:

PH is an H-SFN that meets the following conditions:

H-SFN mod T _{eDRX, H} = (UE_ID_H mod T _{eDRX, H} )

Among them, UE_ID_H is obtained based on a hash ID (Identifier). _TeDRX,H is an eDRX cycle in a superframe unit. Optionally, _TeDRX,H is configured by AMF.

PTW_start is an SFN that meets the following conditions:

SFN=256*i _eDRX

i _eDRX = floor(UE_ID_H/T _eDRX,H )mod 4

PTW_end is an SFN that meets the following conditions:

SFN=(PTW_start+L*100-1)mod 1024

Among them, L is the window length of PTW, and the unit is milliseconds. Optionally, L is configured by AMF.

However, the above example is a further power-saving solution for low-capacity terminal devices in an unconnected state in LTE to monitor paging messages, and for low-capacity terminal devices in an idle or inactive state in a 5G NR system to monitor paging messages, There is no further power saving plan. Moreover, it can be seen from the manner of determining PTW_start shown in the above example that the determination of PTW_start is related to the UE ID, eDRX cycle, and the maximum supported DRX cycle (that is, 256 SFNs). In the above example, the PTW_starts of different terminal devices are first evenly distributed to different H-SFNs in an eDRX cycle. For different terminal devices mapped to the same H-SFN, these terminal devices are further evenly distributed to 4 PTW_start at equal intervals. Among them, the 4 PTW starting points in an H-SFN are determined by the maximum DRX cycle that can be supported. Since one H-SFN has 1024 SFNs, the maximum DRX cycle that can be supported is 256 SFNs, thus one H-SFN There can be 4 PTW_starts at equal intervals. In fact, different DRX cycles can be configured for different terminal devices. When the DRX cycle is less than 256 SFNs, more than 4 PTW_starts can be determined according to the DRX cycle. However, in the eDRX mechanism in LTE, terminal devices with different DRX cycles are distributed in accordance with the maximum DRX cycle. On PTW_start, furthermore, for a terminal device with a DRX cycle less than 256 SFNs, the moment when it monitors the paging message is not evenly distributed on all POs on the entire time axis. On the one hand, this will bring about the problem of unbalanced load among different POs. On the other hand, for POs with a heavier load, it will also increase the probability of paging false alarms.

Based on this, the embodiment of the present application provides a paging method based on enhanced discontinuous reception, and provides an enhanced discontinuous monitoring paging message method for a terminal device in an idle state or an inactive state. Compared with the related technology based on the discontinuous monitoring of the paging message in the DRX cycle, the embodiment of this application is based on the non-continuous monitoring of the paging message in the eDRX cycle. Since the number of SFNs corresponding to the eDRX cycle is greater than the number of SFNs corresponding to the DRX cycle, this application By increasing the period of discontinuous monitoring, the embodiment reduces the power consumption and monitoring overhead of the terminal device, which helps to save the power of the terminal device, especially for low-capacity terminal devices, which can further extend the battery life.

Hereinafter, the technical solution of the present application will be introduced and explained through several exemplary embodiments.

Please refer to FIG. 2, which shows a flowchart of a paging method based on enhanced discontinuous reception provided by an embodiment of the present application. The method can be applied to the system architecture shown in FIG. 1, for example, in an idle state. Or in an inactive terminal device, the method may include the following steps:

Step 210: The core network device sends eDRX configuration information to the terminal device, where the eDRX configuration information includes an eDRX cycle.

The terminal device can receive eDRX configuration information from the core network device. Optionally, the core network device is the aforementioned AMF; the eDRX configuration information is a NAS message.

The eDRX configuration information is used to indicate eDRX-related parameters. Optionally, the eDRX configuration information is determined by the core network device and sent to the terminal device for direct use by the terminal device; or, the eDRX configuration information is negotiated and determined by the terminal device and the core network device For example, the terminal device can carry eDRX-related parameters in the registration request sent to the core network device, and the core network device parses the eDRX-related parameters after receiving the registration request, and sends a confirmation message to the terminal device to complete the eDRX configuration Information negotiation process. The embodiment of this application does not limit the content of the eDRX configuration information. Optionally, the eDRX configuration information includes at least one of the following: eDRX cycle T _eDRX , PTW window length L, PTW_start, and so on.

In an example, the terminal device may also receive DRX configuration information sent by the core network device. The DRX configuration information includes the DRX cycle. The DRX cycle is the exclusive cycle of the terminal device described above, that is, the core network device may be The terminal device configures its dedicated DRX cycle. Optionally, the core network device is AMF; the DRX configuration information is a NAS message. The embodiments of this application do not limit the way the core network device sends DRX configuration information and eDRX configuration information. Optionally, the core network device sends DRX configuration information and eDRX configuration information to the terminal device separately; or, the core network device sends the DRX configuration information and eDRX configuration information to the terminal device at the same time. Sending DRX configuration information and eDRX configuration information; wherein, the DRX configuration information and eDRX configuration information are carried in the same NAS message, and the core network device sends the NAS message to the terminal device.

In another example, the terminal device may also receive paging configuration information from the access network device, and the paging configuration information is used to configure information related to the paging search space. Optionally, the paging configuration information is carried in the system broadcast. The embodiment of this application does not limit the specific content of the paging configuration information. Optionally, the paging configuration information includes at least one of the following: a default DRX cycle, the number of PFs included in a DRX cycle, N, and a PF. The number of POs included N _s , a time domain offset PF_offset used to determine the PF, and so on.

After the terminal device receives the configuration information from the core network device and the access network device, it can determine the PF and PO based on the configuration information. For the determination method of PF and PO, please refer to the foregoing embodiment, which will not be repeated here. One point that needs to be explained is that for a terminal device configured with an eDRX cycle, when the eDRX cycle is less than one superframe, the terminal device _{determines the above PF and PO based on T=T eDRX} ; when the eDRX cycle is greater than or equal to one superframe Next, the terminal device does not _{determine the above PF and PO based on T=T eDRX} , but determines T based on at least one of the following DRX cycles: the DRX cycle configured by the core network device (that is, the DRX cycle exclusive to the terminal device), and the system message broadcasts The DRX cycle (that is, the above-mentioned default DRX cycle) and the DRX cycle configured by the access network device, for example, the terminal device may use the DRX cycle with the smallest value among the above-mentioned DRX cycles as T.

Step 220: The terminal device determines a paging time window when the eDRX cycle is greater than or equal to one superframe.

It can be seen from the analysis of the foregoing embodiment that when the eDRX cycle is greater than or equal to one superframe, the terminal device monitors the paging message on the corresponding PO within the PTW in one eDRX cycle. Therefore, the eDRX cycle is greater than or equal to one superframe. In the case of frames, the terminal device needs to determine the paging time window (PTW). The embodiment of the present application does not limit the manner in which the terminal device determines the PTW. Optionally, the terminal device determines the PTW through calculation; or, the terminal device determines the PTW according to the configuration of the network device. Please refer to the following method embodiment for the description of the terminal device determining the PTW, which will not be repeated here.

Step 230: The terminal device monitors the paging message at the paging occasion corresponding to the terminal device within the paging time window.

In the embodiment of this application, since the determination of the paging occasion (PO) is based on the identification of the terminal device, there is a corresponding relationship between the terminal device and the PO. The paging message is monitored on the corresponding PO. The embodiment of the present application does not limit the source of the paging message. Optionally, the paging message is sent by the access network device to the terminal device; or the paging message is sent by the control plane device to the terminal device. The embodiment of this application does not limit the content of the paging message. Optionally, the paging message includes the identification of the terminal device, the type of service to be carried out, the data size of the service, and so on.

In summary, the technical solution provided by the embodiments of the present application receives the eDRX configuration information sent by the core network device through a terminal device in an idle or inactive state, and the eDRX period in the eDRX configuration information is greater than or equal to one superframe In the case of determining the paging time window, and then monitoring the paging message on the paging occasion corresponding to the terminal device in the paging time window, it provides an enhanced discontinuous monitoring for the terminal device in the idle state or inactive state Method of paging messages. Compared with the related technology based on the discontinuous monitoring of the paging message in the DRX cycle, the embodiment of this application is based on the non-continuous monitoring of the paging message in the eDRX cycle. Since the number of SFNs corresponding to the eDRX cycle is greater than the number of SFNs corresponding to the DRX cycle, this application By increasing the period of discontinuous monitoring, the embodiment reduces the power consumption and monitoring overhead of the terminal device, which helps to save the power of the terminal device, especially for low-capacity terminal devices, which can further extend the battery life.

The following describes how the terminal device determines the paging time window (PTW).

In an example, the above step 220 includes the following steps:

Step 222: The terminal device determines the first superframe where the start radio frame of the paging time window is located.

It can be seen from the description of the foregoing embodiment that determining the PTW actually determines the three parameters of PH, PTW_start, and PTW_end. The terminal device needs to determine the PH first, then determine the PTW_start within the determined PH, and then further determine the PTW_end according to the PTW_start. In the embodiment of the present application, terminal devices with the same eDRX cycle will be distributed in different superframes, so that the situation of paging false alarms can be avoided. Optionally, the terminal device determines the first superframe according to the first identifier and the eDRX cycle; where the first identifier is used to indicate the device identifier of the terminal device. The following exemplarily shows the determination method of the first superframe, and the first superframe is an H-SFN that satisfies the following conditions:

H-SFN mod T _{eDRX, H} = (UE_ID1 mod T _{eDRX, H} )

Among them, _{TeDRX and H} are TeDRX in units of _superframes . UE_ID1 is the first identifier. Optionally, the above method further includes: acquiring the TMSI of the terminal device; determining the first identifier according to the TMSI, that is, the first identifier is calculated by the TMSI based on a certain rule. It is not limited, and optionally, the rule is a hash operation.

Step 224: The terminal device determines the start radio frame of the paging time window in the first superframe.

After the terminal device determines the superframe in which its corresponding paging time window is located, it can determine the start radio frame (PTW_start) of the paging time window in the superframe. The embodiment of the present application provides several ways to determine PTW_start, and these several ways are introduced and explained below.

Exemplarily, the above step 224 includes: the terminal device determines the start radio frame of the paging time window in the first superframe according to the first information, the first information includes a first identifier and a first period; wherein, the first identifier is used To indicate the device identifier of the terminal device, the first period is used to indicate the paging period.

That is, the terminal device can determine PTW_start through calculation. The basis for the terminal device to calculate PTW_start is the first information. The embodiment of the present application does not limit the content of the first information. Optionally, the first information includes the first identifier and the first period; or, the first information further includes the eDRX period. For the introduction and description of the first identifier, please refer to the above step 222, which will not be repeated here. The first period T is used to indicate the paging period. When the eDRX period is less than one superframe, the terminal device _{determines the above PF and PO based on T=T eDRX} , and monitors the paging message on the determined PO, that is, At this time, the terminal device does not need to determine the paging time window, and therefore does not need to determine the parameters related to the paging time window; in the case that the eDRX cycle is greater than or equal to one superframe, the terminal device needs to determine the paging time window based on The paging time window monitors paging messages. In the process of determining the relevant parameters of the paging time window by the terminal device, the first period T needs to be determined. Optionally, the terminal device determines the first period T based on at least one of the following DRX periods: the DRX period configured by the core network device (that is, The above-mentioned terminal device exclusive DRX cycle), the DRX cycle broadcasted in the system message (that is, the above-mentioned default DRX cycle), the DRX cycle configured by the access network device, optionally, the terminal device satisfies the first in the above several cycles The period of the condition is determined as the first period T. Optionally, the first condition includes that the period value of the DRX cycle is the smallest, that is, the terminal device uses the smallest DRX cycle among the foregoing cycles as the first cycle T.

That is, the above PTW_start is an SFN that meets the following conditions:

SFN=T*i _eDRX

The core network device configures PTW_start for each terminal device in the eDRX configuration information. After each terminal device determines the superframe in which it is located, it can determine the paging time window according to the PTW_start configured by the core network device.

In an example, the above step 220 further includes step 226: the terminal device determines the end radio frame of the paging time window according to the start radio frame of the paging time window and the window length of the paging time window. Optionally, the end radio frame (PTW_end) of the paging time window is an SFN that meets the following conditions:

SFN=(PTW_start+L-1)mod 1024

Among them, L is the window length of the paging time window, and the L is in units of radio frames. When L is in milliseconds, L can be multiplied by 100 and substituted into the above formula to determine PTW_end.
