Description

Wireless communication method, terminal device and network device

Technical Field

The embodiment of the application relates to the field of communication, and more particularly, to a wireless communication method, a terminal device and a network device.

Background

In order to be able to inform the terminal device in Radio resource control (Radio Resource Control, RRC) INACTIVE state (rrc_inactive) to enter connected state, a New Radio (NR) introduces an access network paging mechanism.

The paging process sent by the access network comprises the following steps: the Access network releases the terminal device from the connected state to the inactive state, and the Access network still stores the Access Stratum (AS) context of the terminal device. The access network configures paging area configuration information to the terminal device in the process of releasing the terminal device from the connection state to the non-activation state, wherein the paging area configuration information can include any one of the following: closed access group identity (Closed Access Group Identifier, CGI) list information, tracking area identity (Tracking Area Identity, TAI) list information, access network area code list information. The access network and the terminal equipment both maintain the paging area configuration information, if the corresponding configuration of the resident cell of the terminal equipment is not matched with any one of the paging area configuration information configured by the access network for the terminal equipment, the terminal equipment triggers the access network notification area update (RAN Notification Area Update, RNAU) so that the access network can configure new paging area configuration information for the terminal equipment; otherwise, the paging procedure sent by the subsequent access network will fail.

However, in Non-terrestrial network (Non-Terrestrial Network, NTN) systems, since satellites move at high speed relative to the ground, the residence cell of the terminal device may change frequently, and if the above RNAU trigger mechanism is continuously adopted, the problem of excessive power consumption of the terminal device may result.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" is used herein to describe association of associated objects, for example, to indicate that there may be three relationships between the associated objects, for example, a and/or B, may indicate: three cases of A alone, A and B together, and B alone exist.

In the description of the embodiments of the present application, the term "corresponding" may indicate that there is a direct correspondence or an indirect correspondence between the two, or may indicate that there is an association between the two, or may indicate a relationship between the two and the indicated, configured, or the like.

In order to clearly illustrate the ideas of the embodiments of the present application, the related technical contents of the embodiments of the present application will be briefly described first. Embodiments of the present application include at least some of the following.

The main application scenario of 5G is: enhanced mobile Ultra-wideband (Enhance Mobile Broadband, emmbb), low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC), large scale machine type communications (massive Machine Type of Communication, mctc). embbs still target users to obtain multimedia content, services, and data, and their demand is growing very rapidly. Since the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the capability and demand of the eMBB may also vary widely, and thus, a detailed analysis must be performed in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

The inactive state is a new RRC state introduced by the NR system, and is aimed at reducing the delay of the terminal device entering the connection state, where the access network still maintains the AS context of the terminal device, and in view of the core network, the terminal device still is in the connection state, because the NG interface connection of the granularity of the terminal device between the core network and the access network is still maintained, but the Uu interface connection between the access network and the terminal device is released, and compared with the idle state, the terminal device in the inactive state needs to establish a complete Un interface and an NG interface connection, and can enter the connection state only by establishing a Uu interface connection, thereby reducing the delay of the terminal device entering the connection state.

In order to be able to notify the terminal equipment in the inactive state to enter the connected state, the NR introduces an access network paging mechanism, and whenever the core network needs to send data to a certain terminal equipment and the terminal equipment is in the inactive state, the access network triggers an access network paging process to notify the terminal equipment to enter the connected state, where paging area configuration information (i.e. access network paging area configuration) is configured to the terminal equipment by the access network when the terminal equipment is released to the inactive state, where the paging area configuration information is maintained at both the access network side and the terminal equipment side, and may include any one of the following configuration forms: CGI list information, TAI list information, access network area code list information. Wherein each CGI is identified by a public land mobile network (Public Land Mobile Network, PLMN) id+cell (Cell) ID, each TAI is identified by a PLMN id+tac ID, and each access network Area Code is identified by a PLMN id+tac id+access network Area Code (RANAC) ID.

The reason for the access network maintaining paging area configuration information is that: the configuration is needed to send the paging message of the access network, so that the paged terminal is found, and the terminal equipment also needs to maintain the configuration, so that the consistency of the understanding of the access network and the terminal equipment is realized, if the corresponding configuration of the resident cell of the terminal equipment is not matched with any configuration in the paging area configuration information configured to the terminal equipment by the access network, the terminal equipment triggers the RNAU, so that the access network can configure new paging area configuration information for the terminal equipment; otherwise, the paging procedure sent by the subsequent access network will fail.

As described above, in the NTN system, since the satellite moves at a high speed relative to the ground, the residence cell of the terminal device may change frequently, and if the RNAU trigger mechanism as described above is continuously adopted, the problem of excessive power consumption of the terminal device may be caused.

The technical scheme of the application will be described in detail as follows:

example 1

Fig. 2 is an interaction flow chart of a wireless communication method according to an embodiment of the present application, as shown in fig. 2, where the method includes:

s210: the network device sends the first configuration information to the terminal device.

S220: and the terminal equipment performs RNAU according to the first configuration information and the motion information of the terminal equipment.

Wherein the first configuration information includes: configuration information of the periodically triggered RNAU and/or configuration information of the event triggered RNAU. Configuration information of the event-triggered RNAU comprises: and the displacement related information of the terminal equipment and/or the position related information of the terminal equipment.

Optionally, the first configuration information is carried in a system broadcast message or dedicated signaling, but is not limited thereto.

Alternatively, the dedicated signaling is connection release signaling, but is not limited thereto.

Optionally, the configuration information of the periodically triggered RNAU includes: the default execution period of the RNAU, the displacement evaluation period of the terminal device, and at least one displacement evaluation threshold of the terminal device.

It should be understood that the period of the RNAU refers to how often the terminal device performs the RNAU.

Optionally, the configuration information of the periodically triggering RNAU further includes: at least one adjustment parameter of the default execution cycle of the RNAU.

It should be understood that the displacement evaluation period of the terminal device refers to a period for performing displacement evaluation on the terminal device.

It should be appreciated that the at least one displacement evaluation threshold constitutes a plurality of displacement evaluation threshold ranges, each displacement evaluation threshold range corresponding to one of the adjustment parameters of the default execution cycle described above.

Optionally, the adjustment parameter of the default execution period is used to adjust the default execution period, where the terminal device may adjust the default execution period according to the adjustment parameter by at least one of the following manners, but is not limited thereto:

adding an adjustment parameter on the basis of a default execution period, wherein the value of the adjustment parameter can be positive or negative;

multiplying the adjustment parameter on the basis of the default execution period.

It should be understood that the present application does not limit the above adjustment parameters.

Optionally, the displacement related information of the terminal device includes at least one displacement threshold, but is not limited thereto.

Optionally, the location related information of the terminal device includes: the location reference information, or the location related information of the terminal device includes at least one of the following: at least one CGI, at least one TAC, at least one RANAC.

It should be understood that in the present application, each location information of the terminal device is represented using latitude and longitude information or spatial coordinates.

Optionally, the motion information of the terminal device is a displacement amount of the terminal device in a displacement evaluation period, or the motion information of the terminal device is current position information of the terminal device.

In summary, in the present application, the terminal device performs the RNAU according to the first configuration information and the motion information of the terminal device, and compared with the existing RNAU triggering manner, this manner does not cause frequent triggering of the RNAU, so that power consumption of the terminal device can be reduced.

Example 2

As described above, the terminal device may perform the RNAU according to configuration information of periodically triggering the RNAU and motion information of the terminal device. This is described in detail below:

optionally, the motion information of the terminal device is a displacement amount of the terminal device in a displacement evaluation period. The terminal equipment determines a displacement threshold range corresponding to the displacement amount in the displacement evaluation period according to at least one displacement evaluation threshold, determines a first adjustment parameter in at least one adjustment parameter of a default execution period according to the displacement threshold range, and finally adopts the default execution period to perform RNAU, or adjusts the default execution period according to the first adjustment parameter to periodically perform RNAU.

It should be understood that it is assumed that the terminal device multiplies the adjustment parameter on the basis of the default execution period to adjust the default execution period. Then when the first adjustment parameter determined by the terminal device is 1, this indicates that no adjustment of the default execution period is required, and therefore the terminal device uses the default execution period to perform the RNAU. Alternatively, it is assumed that the terminal device adds an adjustment parameter on the basis of the default execution period to adjust the default execution period. Then when the first adjustment parameter determined by the terminal device is 0, this indicates that no adjustment of the default execution period is required, and therefore the terminal device uses the default execution period to perform the RNAU.

Optionally, the larger the displacement amount of the terminal device in the displacement evaluation period is, the smaller the adjusted period of the RNAU is, and the smaller the displacement amount of the terminal device in the displacement evaluation period is, the larger the adjusted period of the RNAU is, but not limited thereto.

Example 1, assume that a terminal device is configured with two displacement evaluation thresholds, S1 and S2, respectively, where S1< S2. Thus, the two displacement evaluation thresholds constitute three displacement evaluation threshold ranges, respectively being less than or equal to S1, less than S1 and greater than or equal to S2, and greater than S2. Assuming that these three displacement evaluation threshold ranges are referred to as a displacement evaluation threshold range 1, a displacement evaluation threshold range 2, and a displacement evaluation threshold range 3, it is assumed that the terminal device multiplies the adjustment parameters on the basis of the default execution period, and the adjustment parameters corresponding to the displacement evaluation threshold range 1, the displacement evaluation threshold range 2, and the displacement evaluation threshold range 3 are 1,2, and 3, respectively. If the terminal equipment determines that the displacement evaluation threshold range to which the displacement amount in the displacement evaluation period belongs is a displacement evaluation threshold range 1, the terminal equipment is in a normal state or a normal state, and the corresponding adjustment parameter is 1, namely the terminal equipment adopts a default execution period to perform RNAU. If the terminal equipment determines that the displacement evaluation threshold range to which the displacement amount in the displacement evaluation period belongs is a displacement evaluation threshold range 2, the terminal equipment is in a medium speed state, and the corresponding adjustment parameter is 2, namely the terminal equipment adopts T/2 to carry out RNAU. T represents a default execution period. If the terminal equipment determines that the displacement evaluation threshold range to which the displacement amount in the displacement evaluation period belongs is a displacement evaluation threshold range 3, the terminal equipment is in a high-speed state, and the corresponding adjustment parameter is 3, namely the terminal equipment adopts T/3 to perform RNAU.

Example 2, assume that a terminal device is configured with two displacement evaluation thresholds, S1 and S2, respectively, where S1< S2. Thus, the two displacement evaluation thresholds constitute three displacement evaluation threshold ranges, respectively being less than or equal to S1, less than S1 and greater than or equal to S2, and greater than S2. Assuming that these three displacement evaluation threshold ranges are referred to as a displacement evaluation threshold range 1, a displacement evaluation threshold range 2, and a displacement evaluation threshold range 3, it is assumed that the terminal device adds the adjustment parameters on the basis of the default execution period, and the adjustment parameters corresponding to the displacement evaluation threshold range 1, the displacement evaluation threshold range 2, and the displacement evaluation threshold range 3 are 0, -1, and-2, respectively. If the terminal equipment determines that the displacement evaluation threshold range to which the displacement amount in the displacement evaluation period belongs is a displacement evaluation threshold range 1, the terminal equipment is in a normal state or a normal state, and the corresponding adjustment parameter is 0, namely the terminal equipment adopts a default execution period to perform RNAU. If the terminal equipment determines that the displacement evaluation threshold range to which the displacement amount in the displacement evaluation period belongs is a displacement evaluation threshold range 2, the terminal equipment is in a medium speed state, and the corresponding adjustment parameter is-1, namely the terminal equipment adopts T-1 to perform RNAU. If the terminal equipment determines that the displacement evaluation threshold range to which the displacement amount in the displacement evaluation period belongs is a displacement evaluation threshold range 3, the terminal equipment is in a high-speed state, and the corresponding adjustment parameter is-2, namely the terminal equipment adopts T-2 to perform RNAU.

It should be understood that the division manner of determining the displacement evaluation threshold range according to the displacement evaluation threshold in examples 1 and 2 is not limited to the above-described division manner, for example: three displacement evaluation threshold ranges, respectively, are less than S1, greater than or equal to S1 and greater than or equal to S2, and greater than S2. Alternatively, the three displacement evaluation threshold ranges are respectively less than S1, greater than or equal to S1 and greater than S2, and greater than or equal to S2.

In summary, in the present application, the terminal device performs the RNAU according to configuration information of periodically triggering the RNAU and motion information of the terminal device. Compared with the existing RNAU triggering mode, the mode does not cause frequent RNAU triggering, and therefore power consumption of terminal equipment can be reduced.

Example 3

As described above, the terminal device may perform the RNAU according to configuration information of the event-triggered RNAU and motion information of the terminal device. This is described in detail below:

optionally, the configuration information of the event triggering RNAU includes: and the position related information of the terminal equipment. The location related information includes: position reference point information. The motion information of the terminal equipment is the current position information of the terminal equipment. Based on this, the terminal device determines a first relative distance of the terminal device with respect to the position reference point information based on the current position information and the position reference point information.

If the first relative distance is greater than or equal to a first displacement threshold, the terminal equipment performs RNAU; or,

if the first relative distance is smaller than or equal to the second displacement threshold, the terminal equipment performs RNAU; or,

if the first relative distance is larger than the second displacement threshold and smaller than the first displacement threshold, the terminal equipment performs RNAU; or,

if the first relative distance is larger than a first displacement threshold, the terminal equipment performs RNAU; or,

if the first relative distance is smaller than the second displacement threshold, the terminal equipment performs RNAU; or,

if the first relative distance is greater than or equal to the second displacement threshold and less than or equal to the first displacement threshold, the terminal equipment performs RNAU; or,

if the first relative distance is larger than the second displacement threshold and smaller than or equal to the first displacement threshold, the terminal equipment performs RNAU; or,

and if the first relative distance is larger than or equal to the second displacement threshold and smaller than the first displacement threshold, the terminal equipment performs RNAU.

Optionally, the first displacement threshold is greater than the second displacement threshold.

Optionally, the configuration information of the event triggering RNAU further includes: and the displacement related information of the terminal equipment. The displacement-related information includes: a first displacement threshold and/or a second displacement threshold.

It should be understood that the first displacement threshold and/or the second displacement threshold may not be included in the configuration information of the event-triggered RNAU, for example: the first displacement threshold and/or the second displacement threshold are predefined, and in any case, the method for obtaining the first displacement threshold and/or the second displacement threshold is not limited in this application.

In summary, in the present application, the terminal device performs the RNAU according to configuration information of the event-triggered RNAU and motion information of the terminal device. Compared with the existing RNAU triggering mode, the mode does not cause frequent RNAU triggering, and therefore power consumption of terminal equipment can be reduced.

Example 4

optionally, the configuration information of the event triggering RNAU includes: and the displacement related information of the terminal equipment. The displacement-related information includes: and a third displacement threshold. The motion information of the terminal equipment is the current position information of the terminal equipment. Based on this, the terminal device may determine a second relative distance of the terminal device with respect to the default position reference point information based on the current position information and the default position reference point information.

If the second relative distance is greater than or equal to a third displacement threshold, the terminal equipment performs RNAU; or,

and if the second relative distance is larger than the third displacement threshold, the terminal equipment performs RNAU.

Optionally, the default location reference point information is a geographical location when the terminal device is released to the inactive state last time or a geographical location when the terminal device receives the first configuration information last time, but is not limited thereto.

Example 5

optionally, the configuration information of the event triggering RNAU includes: position-related information of the terminal device and displacement-related information of the terminal device; the location related information includes: position reference point information; the displacement-related information includes: and a third displacement threshold. Based on this, the terminal device may determine a first relative distance of the terminal device with respect to the position reference point information according to the current position information and the position reference point information; and determining a second relative distance of the terminal equipment relative to the default position reference point information according to the current position information and the default position reference point information.

If the first relative distance is greater than or equal to the first displacement threshold and the second relative distance is greater than or equal to the third displacement threshold, the terminal equipment performs RNAU; or,
