Description

Data transmission method, device and equipment

Technical Field

The present disclosure relates to the field of communications, and in particular, to a data transmission method, apparatus, and device.

Background

When the network equipment and the terminal equipment are connected, the network equipment needs to page the terminal equipment at the paging moment of the terminal equipment, and when the network equipment successfully pages the terminal equipment, the network equipment and the terminal equipment are connected.

Currently, the paging time window of the terminal device can be determined through the receiving period of the terminal device, so as to determine the paging time window of the terminal device. For example, when paging occurs, the paging message sent by the core network device to the base station may carry extended discontinuous reception eDRX (extended discontinious reception, eDRX) of the terminal device, and the terminal device and the base station may determine a paging time window of the terminal device according to eDRX, where the base station pages the terminal device. However, the coverage of the signal of the network device to the cell where the terminal device is located is discontinuous coverage, for example, when the signal of the network device 1 leaves the cell, the signal of the network device 2 does not start serving the cell yet, and when the paging time window calculated by the network device according to eDRX is located in a discontinuous coverage time period, the network device cannot page the terminal device, which results in a low success rate of paging the terminal device by the network device.

A base station may contain one or more co-sited or non-co-sited TRPs.

Terminal equipment: is a device with wireless receiving and transmitting function. The terminal device may be deployed on land, including indoors or outdoors, hand-held, wearable or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a vehicle-mounted terminal device, a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a wearable terminal device, or the like. The terminal device according to the embodiments of the present application may also be referred to as a terminal, a User Equipment (UE), an access terminal device, a vehicle terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent, or a UE apparatus, etc. The terminal device may also be fixed or mobile.

Paging time window set: the paging time window set includes at least one paging time window. The paging time window is a paging interval of the terminal device, within which the network device can successfully page to the terminal device.

The paging time window set is described below in conjunction with fig. 1.

Fig. 1 is a schematic diagram of a paging time window set according to an embodiment of the present application. Referring to fig. 1, a set of paging time windows is included. Wherein the paging time window set includes a paging time window A, a paging time window B and a paging time window C. The paging time window set shown in fig. 1 is a paging time window set within one period (e.g., one superframe period of 2.91 hours, or 24 hours). The starting position of each paging time window in the paging time window set in one superframe period can be identified by using a specific superframe number and a radio frame number, and can also be identified by using natural time. For example, the starting position of the paging time window a is the fifth radio frame in the second superframe period, or the starting position of the paging time window a is 12 hours for 3 minutes and 20 seconds, and the above scheme is repeated in the next period.

In the related art, the terminal device may determine a paging time window of the terminal device through the reception period, and further determine a paging occasion of the terminal device. For example, the terminal device may determine eDRX and determine a paging time window for the terminal device based on eDRX, and calculate all paging occasions for the terminal device within the paging time window. However, the coverage of the network device to the cell where the terminal device is located is discontinuous coverage, for example, when the signal of the network device 1 leaves the cell, the signal of the network device 2 does not start to serve the cell yet, and in this period, the network device cannot establish a connection with the terminal device, and if the paging time window of the terminal device is located in this period, the network device cannot successfully page the terminal device, so that the network device cannot establish a connection with the terminal device, and the success rate of paging the terminal device by the network device is low.

In order to facilitate understanding, the above technical problems will be described in detail with reference to fig. 2.

Fig. 2 is a schematic view of discontinuous coverage according to an embodiment of the present application. Referring to fig. 2, the network device a, the network device B, the terminal device a, and the terminal device B are included. Wherein the signal of the network device a covers the cell in which the terminal device a is located. The signal of the network device B covers the cell in which the terminal device B is located, but does not cover the cell in which the terminal device a is located yet.

Referring to fig. 2, when the coverage signal of the network device a leaves the cell range where the terminal device is located, the signal of the network device B can cover the cell where the terminal device a is located after a preset period (e.g., 30 seconds) due to the discontinuous coverage of the network device a and the network device B, so if the paging window of the terminal device a is within 30 seconds, the network device cannot page the terminal device a, which further results in a low success rate of paging the terminal device by the network device.

In order to solve the technical problem that in the related art, the success rate of paging terminal equipment by network equipment is low, the embodiment of the application provides a data transmission method, and the terminal equipment sends first information to core network equipment, wherein the first information is used for determining a paging time window set for receiving paging by the terminal equipment, the first information comprises a second paging time window set of the terminal equipment, or at least one network equipment serves the time information of the terminal equipment, and the terminal equipment receives the first paging time window set of the terminal equipment sent by the core network equipment. In the above method, since the terminal device can negotiate with the core network device about the paging time window set that the network device can page the terminal device, after the core network device sends the paging time window to the network device, the network device and the terminal device use the same paging time window that can page, and since the time information is the time information of the cell where the network device starts to serve the terminal device, the paging time window of the terminal device is in the period of the serving cell of the network device, even if the signal coverage of the network device to the cell where the terminal device is located is discontinuous coverage, the network device can accurately page the terminal device according to the paging time window, thereby improving the success rate of the network device paging the terminal device.

Next, an application scenario of the embodiment of the present application will be described with reference to fig. 3.

Fig. 3 is a schematic view of an application scenario provided in the embodiment of the present application. Referring to fig. 3, the network device, the terminal device and the core network device are included. The core network device is respectively in communication connection with the network device and the terminal device. The terminal device may send the paging time window set of the terminal device to the core network device, and after the core network device receives the paging time window set, the core network device may send the paging time window set to the network device. After the network device receives the paging time window set of the terminal device, a page may be initiated to the terminal device within the paging time window set. Because the paging time window set of the terminal equipment is determined according to eDRX and the moment when the network equipment starts to serve the cell where the terminal equipment is located, the paging time window set of the terminal equipment is in the period of coverage of the cell by the network equipment, even if the signal coverage of the cell where the terminal equipment is located by the network equipment is discontinuous coverage, the network equipment can accurately page the terminal equipment according to the paging time window set, and further the success rate of paging the terminal equipment by the network equipment is improved. The technical scheme shown in the application is described in detail through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and for the same or similar content, the description will not be repeated in different embodiments.

Fig. 4 is a flow chart of a data transmission method according to an embodiment of the present application. Referring to fig. 4, the method may include:

s401, the terminal equipment sends first information to the core network equipment.

The execution body of the embodiment of the application may be a terminal device, or may be a data transmission device provided in the terminal device. Alternatively, the data transmission device may be implemented by software, or may be implemented by a combination of software and hardware.

The first information is used to determine a set of paging time windows for which the terminal device receives pages. The paging time window is a period in which the terminal device receives a page. For example, the terminal device may receive a page of the network device during a paging time window period, and the network device may page the terminal device during the paging time window period. The paging time window set includes paging time windows in which at least one network device can page the terminal device.

The first information comprises a second set of paging time windows for the terminal device or time information for at least one network device to serve the terminal device. The second set of paging time windows is a set of paging time windows determined by the terminal device. For example, the second paging time window set may be a paging time window set obtained by the terminal device according to eDRX and time information.

The second paging time window set of the terminal device includes: within a preset period range, the starting time information of each paging time window and the window length information of each paging time window, or the ending time information of each paging time window and the window length information of each paging time window; or, in a preset time period, the starting time information of each paging time window and the window length information of each paging time window, or the ending time information of each paging time window and the window length information of each paging time window. For example, start-stop time information of each paging time window, or end time and window length information of each paging time window, is within 1024 superframes.

The time information of the network device serving the terminal device may include at least one of the following information: the network equipment starts to serve the first time information of the terminal equipment, the network equipment ends to serve the second time information of the terminal equipment, and the duration of the network equipment serving the terminal equipment.

The first time information includes a time at which the at least one network device starts serving the cell in which the terminal device is located. For example, the first time information may include ephemeris information for a plurality of network devices. For example, when the time when the network device a starts to serve the cell where the terminal device is located is time a, and when the time when the network device B starts to serve the cell where the terminal device is located is time B and the time when the network device C starts to serve the cell where the terminal device is located is time C, the first time information includes time a, time B and time C. Optionally, if the first time information includes a plurality of time instants, the plurality of time instants may be arranged in time sequence. For example, the first time information includes a time a and a time B, and if the time of the time a is before the time of the time B, the time a is before the time B in the first time information.

Alternatively, the moment when the network device starts serving the cell in which the terminal device is located may be an absolute time. For example, the moment when the network device starts serving the cell in which the terminal device is located may be a specific absolute time point (e.g., 8 points, 9 points, etc.) within a time period (e.g., 24 hours).

The second time information includes a time at which the at least one network device ends serving the cell in which the terminal device is located. For example, the second time information may include ephemeris information for a plurality of network devices. For example, when the time when the network device a ends the cell in which the service terminal device is located is time a, and when the time when the network device B ends the cell in which the service terminal device is located is time B and when the time when the network device C ends the cell in which the service terminal device is located is time C, the second time information includes time a, time B, and time C.

Alternatively, the time at which the network device ends serving the cell in which the terminal device is located may be absolute time. For example, the moment when the network device ends serving the cell where the terminal device is located may be a specific absolute time point (e.g., 8 points, 9 points, etc.) within a time period (e.g., 24 hours).

The duration of the network device for serving the terminal device is a period between the time when the network device starts serving the terminal device and the time when the network device ends serving the terminal device. For example, if the time when the network device starts to serve the cell in which the terminal device is located is time a, the time when the network device ends to serve the cell in which the terminal device is located is time B, and the duration of the network device serving the terminal device is the time difference between time B and time a.

Alternatively, the terminal device may receive the time information sent by the network device. For example, the network device may broadcast time information such as a time when the network enters a cell in which the terminal device is located, a time when the network device leaves the cell in which the terminal device is located, and the terminal device may receive the broadcast to obtain time information when the network device serves the terminal device.

Optionally, when the first information is the second paging time window set, the terminal device may determine the second paging time window set according to eDRX and time information of the network device serving the terminal device. When the first information is time information of at least one network device serving a terminal device, the terminal device sends the first information to a core network device specifically: the terminal equipment receives the time information of the service terminal equipment sent by the at least one network equipment, and the terminal equipment sends the time information of the service terminal equipment of the at least one network equipment to the core network equipment. For example, the terminal device may receive time information broadcast by the network device, and after the terminal device obtains the time information of the network device, send the time information of the network device to the core network device.

Optionally, the terminal device may send the first information to the core network device through the following possible implementation manner: the terminal device sends the first information when sending a tracking area update request message or an attach request message to the core network device. For example, when the terminal device and the core network device perform tracking area update, the first information may be carried in a tracking area update request message sent by the terminal device to the core network device.

S402, the core network device sends a first paging time window set of the terminal device to the terminal device and the network device.

Optionally, when the first information sent by the terminal device to the core network device is a second paging time window set of the terminal device, the core network device may determine the first paging time window set according to the second paging time window set, and send the first paging time window set to the terminal device and the network device respectively. Alternatively, the first set of paging time windows may be the same as or different from the second set of paging time windows. For example, when the terminal device sends the second paging time window set to the core network device, the core network device may adjust the second paging time window set (e.g., shift left or shift right for a period of time) to obtain the first paging time window set, and if the core network device does not need to adjust the second paging time window set, the first paging time window set is the same as the second paging time window set. Therefore, after the core network equipment adjusts the second paging time window set, the network equipment and the terminal equipment can obtain the same paging time window set, so that the network equipment can successfully page the terminal equipment in the period of the paging time window set, and the success rate of paging the terminal equipment by the network equipment is improved.

Optionally, the terminal device receives the first paging time window set sent by the core network device when receiving the tracking area update response message or receiving the attach response message.

Optionally, when the first information sent by the terminal device to the core network device includes time information of at least one network device serving the terminal device, the core network device may determine a first paging time window set of the terminal device according to eDRX and the time information, and send the first paging time window set to the terminal device and the network device. Because the time information is the time information of the cell where the terminal equipment is served by the network equipment, the first paging time window set of the terminal equipment is in the time zone of the serving cell of the network equipment, even if the signal coverage of the network equipment to the cell where the terminal equipment is located is discontinuous coverage, the network equipment can accurately page the terminal equipment according to the paging time window set, and in this way, the time zone of the paging time window set received by the network equipment and the terminal equipment can be ensured to be the same, so that the network equipment can successfully page the terminal equipment in the time zone of the paging time window set, and the success rate of paging the terminal equipment by the network equipment is improved.

The embodiment of the application provides a data transmission method, in which a terminal device sends first information to a core network device, where the first information is used to determine a paging time window set for receiving paging by the terminal device, the first information includes a second paging time window set of the terminal device, or at least one network device serves time information of the terminal device, and the terminal device receives the first paging time window set of the terminal device sent by the core network device. In the above method, since the terminal device and the core network device can negotiate the paging time window set that the network device can page the terminal device, after the core network device sends the paging time window set to the network device, the network device and the terminal device use the same paging time window set that can page, and since the time information is the time information of the cell where the network device starts to serve the terminal device, the paging time window set of the terminal device is in the period of the serving cell of the network device, even if the signal coverage of the network device to the cell where the terminal device is located is discontinuous coverage, the network device can accurately page the terminal device according to the paging time window set, thereby improving the success rate of the network device paging the terminal device.

On the basis of the embodiment shown in fig. 4, there are two cases that the terminal device sends the first information to the core network device, and when the first information is different, the process of the data transmission method is also different, and the process of the two data transmission methods will be described below with reference to fig. 5 to 8.

Fig. 5 is a flowchart of another data transmission method according to an embodiment of the present application. In the embodiment shown in fig. 5, the execution body may be a terminal device, the first information includes a second paging time window set of the terminal device, and referring to fig. 5, the method includes:

s501, the terminal equipment determines at least one third paging time window according to the terminal equipment identification and the eDRX.

Optionally, the terminal device determines, according to the identifier of the terminal device and eDRX, at least one third paging window as the prior art, which is not described in detail in the embodiment of the present application.

S502, the terminal equipment determines a second paging time window set according to the second information.

The second information includes at least one of the following information: the method comprises the steps of at least one third paging time window, a terminal equipment identifier, extended discontinuous reception eDRX, ephemeris information, first time information that at least one network equipment starts to serve the terminal equipment, second time information that the at least one network equipment ends to serve the terminal equipment, and duration that the at least one network equipment serves the terminal equipment.

Optionally, the terminal device may obtain eDRX of the terminal device and an identifier of the terminal device according to the network configuration information. For example, the network configuration information of the terminal device includes the eDRX cycle of the terminal device and the identity of the terminal device, and thus, the eDRX cycle and the identity of the terminal device can be obtained through the network configuration information. Optionally, the terminal device obtains a third paging time window according to eDRX and the identifier of the terminal device.

Optionally, for any third paging time window in the second information, the terminal device may determine the second paging time window set by using the following possible implementation manner: it is determined whether there is a time in the first time information that is the same as the starting time of the third paging time window. Wherein the starting time is the time when the third paging time window starts. For example, the third paging window starts at time 1, and the starting time is time 1. For example, the first time information includes time 1, time 2, time 3, and time 4, and if the start time is time 1, time 2, time 3, or time 4, it is determined that the first time information has the same time as the start time, and if the start time is time 5, it is determined that the first time information does not have the same time as the start time.

And if the first time information has the same time as the starting time, determining the third paging time window as a second paging time window of the terminal equipment. For example, if the first time information includes the same time as the starting time, it indicates that the network device has started to serve the cell in which the terminal device is located at the starting time, and therefore, the network device may successfully page the terminal device in the third paging time window.

If the first time information does not have the same time as the starting time, determining adjacent time adjacent to the starting time in the first time information according to the starting time. For example, the first time information includes time 1, time 2, and time 3, where time 1 is earlier than time 2, time 2 is earlier than time 3, and if the start time is between time 1 and time 2, the adjacent time adjacent to the start time is time 1 and time 2.

And determining a second paging time window of the terminal equipment according to the starting time and the adjacent time. Optionally, the second paging time window of the terminal device is determined according to the starting time and the adjacent time, where the following two situations exist:

case 1: the number of adjacent moments of the start moment is 1.

If the number of the adjacent time points is 1, the starting time point of the third time window is moved to the adjacent time point, and a second paging time window of the terminal equipment is obtained. For example, if the starting time is the earliest or latest among the multiple times in the first time information, only one adjacent time exists in the starting time, and at this time, the starting time of the third time window is moved to the adjacent time, so as to obtain the second paging time window of the terminal device.

The procedure for determining a second paging window in this case is described below with reference to fig. 6.

Fig. 6 is a schematic diagram of determining a second paging time window according to an embodiment of the present application. Please refer to fig. 6, which includes first time information. The first time information includes a time a, a time B, and a time C, where time a is earlier than time B, and time B is earlier than time C.

Referring to fig. 6, when the start time is earlier than the time a, the adjacent time of the start time in the first time information is the time a, and at this time, the third paging time window is moved rightward until the start time coincides with the time a, so as to obtain the second paging time window. And when the starting time is later than the time C, the adjacent time of the starting time in the first time information is the time C, and at the moment, the third paging time window is moved leftwards until the starting time coincides with the time C, so that the second paging time window is obtained.

Case 2: the number of adjacent moments of the start moment is 2.

If the number of adjacent moments is 2, the time difference between the starting moment and the second moment is obtained. Wherein the second time is an adjacent time after the start time. For example, if the start time is later than the earliest time in the first time information and earlier than the latest time in the first time information, the number of adjacent times of the start time is 2. For example, the first time information includes a time a, a time B, and a time C, where the time a is earlier than the time B, the time B is earlier than the time C, and if the start time is between the time a and the time B, the adjacent time of the start time is the time a and the time B, and the time B is later than the start time, so the second time is the time B.

Alternatively, the time difference may be determined by the start time and the second time. For example, if the start time is 9 points and the second time is 9 points and 15 minutes, the time difference between the start time and the second time is 15 minutes.

And determining a second paging time window of the terminal equipment according to the time difference. Optionally, determining a second paging time window of the terminal device according to the time difference, specifically includes: if the time difference is smaller than the first threshold, the starting time is moved to the second time, and a second paging time window of the terminal equipment is obtained. For example, if the starting time is 9 points, the second time is 9 points and 5 minutes, and the first threshold is 10 minutes, the time difference between the starting time and the second time is 5 minutes, and the time difference is smaller than the first threshold, so that the third paging time window is moved rightward for 5 minutes until the starting time and the second time overlap, and the second paging time window is obtained.

If the time difference is greater than or equal to the first threshold, the starting time is moved to a third time, and a second paging time window of the terminal equipment is obtained. Wherein the third time is an adjacent time before the start time. For example, if the time adjacent to the start time is time a and time B, the start time is later than time a and earlier than time B, time a is determined as the third time.

The procedure of determining the second paging time window of one terminal device in this case will be described with reference to fig. 7.

Fig. 7 is a schematic diagram of another determination of a second paging time window according to an embodiment of the present application. Please refer to fig. 7, which includes first time information. The first time information includes a time a, a time B, and a time C, where time a is earlier than time B, and time B is earlier than time C.

Referring to fig. 7, when the start time is between time a and time B, adjacent times of the start time in the time information are time a and time B. And determining the time difference between the starting time and the time B, and when the time difference is smaller than the first threshold value, moving the third paging time window to the right until the starting time and the time B coincide, so as to obtain a second paging time window because the time B is the second time. When the time difference is greater than or equal to the first threshold, the time A is the third time, so that the third paging time window is moved leftwards until the starting time coincides with the time A, and the second paging time window is obtained. Thus, for any one of the third paging time windows, a corresponding second paging time window can be obtained, and a second paging time window set is further obtained.

Alternatively, the starting time may be an absolute time within a time period. For example, when 24 hours are around one time, the starting time may be 9, 10, 11 or other absolute times. Alternatively, the starting time may be a relative time of the serving cell of the network device. For example, when the time when the network device starts to serve the cell where the terminal device is located is 0, the starting time may be further noted with respect to the time. For example, the start time may be 5 minutes after the time at which the network device starts serving the cell in which the terminal device is located. Thus, the network equipment can accurately page the terminal equipment, and the success rate of paging the terminal equipment by the network equipment is improved.

S503, the terminal equipment sends a second paging time window set to the core network equipment.

After the terminal device determines the second set of paging time windows, the terminal device may send the second set of paging time windows to the core network device. For example, the terminal device and the core network device may send the second set of paging time windows to the core network device during an attach procedure or a tracking area update procedure.

S504, the core network device sends a first paging time window set to the terminal device and the network device.

It should be noted that the execution process of step S504 is the same as the execution process of step S402, and this will not be described in detail in the embodiment of the present application.

S505, the network equipment pages the terminal equipment according to the first paging time window set.

Optionally, after the network device receives the first paging time window set of the terminal device sent by the core network device, the network device may page the terminal device in a period of the first paging time window set.

The embodiment of the application provides a data transmission method, a terminal device determines at least one third paging time window according to a terminal device identifier and eDRX, and the terminal device determines a second paging time window set according to second information, wherein the second information comprises at least one of the following information: the at least one third paging time window, the terminal equipment identifier, the extended discontinuous reception eDRX, the ephemeris information, the first time information that the at least one network equipment starts to serve the terminal equipment, the second time information that the at least one network equipment ends to serve the terminal equipment, the duration that the at least one network equipment serves the terminal equipment, the terminal equipment sends a second paging time window set to the core network equipment, the core network equipment sends a first paging time window set to the terminal equipment and the network equipment, and the network equipment pages the terminal equipment according to the first paging time window set. In this way, the terminal device can determine the paging time window set of the terminal device according to eDRX and time information, and because the time information is the time information of the network device serving the terminal device, the paging time window set of the terminal device is in the period of the network device serving the cell, even if the signal coverage of the network device to the cell where the terminal device is located is discontinuous coverage, the network device can accurately page the terminal device according to the paging time set window, thereby improving the success rate of the network device paging the terminal device.

Referring to fig. 9, the network device a, the network device B, the network device C, and the terminal device are included. The terminal device may receive the time a transmitted by the network device a, the time B transmitted by the network device B, and the time C transmitted by the network device C.

And the terminal equipment obtains first time information according to the time A, the time B and the time C. The first time information includes a time a, a time B, and a time C, and since the time a is earlier than the time B, the time B is earlier than the time C, and therefore, in the time information, the time a is before the time B, and the time B is before the time C.

Optionally, in the actual application process, since the terminal device may connect to the network signal of the neighboring cell of the cell where the terminal device is located, the first time information may also include a time when the network device starts to serve the neighboring cell. For example, if the time when the network device serves the cell where the terminal device is located is time 1 and the time when the network device serves the neighboring cell is time 2, the first time information may include time 1 and time 2. Optionally, the time information may also be time information of a cell adjacent to the cell where the network device serves the terminal device, which is not described in detail in this embodiment of the present application.
