Description

Wireless communication method, terminal equipment and network equipment

Technical Field

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

Background

In a New Radio (NR) system, when a terminal device needs to enter a connected state, the terminal device initiates a connection to a network device by performing a random procedure. However, if the camping cell of the terminal device has a problem that the uplink coverage area and the downlink coverage area are not matched, the terminal device cannot successfully send a Message (Msg) 1 and/or Msg3 to the network device, so that the terminal device cannot enter a connected state, and in this case, the terminal device needs to record a connection establishment failure (Connection Establishment Failure, CEF) report.

At present, in the moving process of the terminal equipment, if the terminal equipment continuously experiences multiple connection failures, the terminal equipment only records one CEF report, and the CEF report mainly records the specific condition of the last connection failure, the connection failure times of the terminal equipment in the cell where the last connection failure is located, and the like. If the terminal equipment enters a connection state, the terminal equipment can send the CEF report to the network equipment so that the network equipment can identify the unmatched positions of uplink and downlink coverage and further perform network optimization. At present, the way of recording only one CEF report may cause the system to miss the situation of recording some uplink and downlink coverage mismatch and corresponding positions, thereby causing the problem that network optimization is not comprehensive enough. However, if the terminal device continuously experiences multiple connection failures and the terminal device records one CEF report at each connection failure, this will lead to problems of excessive power consumption of the terminal device and excessive consumption of air interface resources. Therefore, how to more reasonably select to record the CEF report is a technical problem to be solved in the present application.

Prior to introducing the technical solutions of the present application, the following description will explain the relevant knowledge of the present application:

CEF report:

after the terminal equipment selects/reselects a resident cell or enters an inactive state according to a cell downlink measurement result, when the terminal equipment needs to enter a connection state, the terminal equipment initiates connection to the network equipment by executing a random process. However, if the camping cell of the terminal device has a problem that the uplink coverage area is not matched with the downlink coverage area, the terminal device cannot successfully send the Msg1 and/or the Msg3 to the network device, so that the terminal device cannot enter a connection state, and in this case, the terminal device needs to record a connection CEF report. At present, in the moving process of the terminal equipment, if the terminal equipment continuously experiences multiple connection failures, the terminal equipment only records one CEF report, and the CEF report mainly records the specific condition of the last connection failure, the connection failure times of the terminal equipment in the cell where the last connection failure is located, and the like.

Illustratively, the components of asn.1 reported by CEF are as follows (in terms of ts.38.331):

as can be seen, the CEF report includes the following:

(1) The downlink signal measurement result of the cell where the last connection failure is located;

(2) Position information of last occurrence of connection failure;

(3) The downlink signal measurement result of the adjacent cell before the last connection failure occurs;

(4) The number of times of connection failure occurs in the cell where the last connection failure is located;

(5) Random access related information;

(6) From connection establishment/restoration to the time when the network device request to report the CEF is received.

Further, if the terminal device enters the connection state, the terminal device may send the CEF report to the network device, so that the network device identifies a location where uplink coverage is not matched with downlink coverage, and further performs network optimization. At present, the method of recording only one CEF report may cause the system to miss some cases of uplink and downlink coverage mismatch, thereby causing a problem that network optimization is not comprehensive enough. However, if the terminal device continuously experiences multiple connection failures and the terminal device records one CEF report at each connection failure, this will lead to problems of excessive power consumption of the terminal device and excessive consumption of air interface resources. Therefore, how to more reasonably select to record the CEF report is a technical problem to be solved in the present application.

In the present application, the terminal device records only one CEF report for a plurality of connection failures occurring at the same location or at approximately the same location, and records the CEF reports corresponding to the plurality of different locations for connection failures occurring at different locations. On the one hand, the system can be ensured not to miss and record the unmatched conditions and corresponding positions of uplink and downlink coverage, and further network optimization is more comprehensive. On the other hand, the power consumption of the terminal equipment and the consumption of air interface resources can be reduced.

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

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, the method includes the following steps:

s210: when the connection of the terminal equipment fails, the terminal equipment judges whether a preset condition is met or not; wherein the preset conditions include at least one of the following: the distance between the location of the terminal device and the location of the at least one historical CEF report record is greater than or equal to a distance threshold; the time interval between the current time and the time of recording of the second CEF report is greater than or equal to a time threshold;

s220: if the preset condition is met, the terminal equipment records a first CEF report;

s230: the terminal device sends a first CEF report to the network device.

It should be understood that in this application, the terminal device connection failure is also referred to as a terminal device radio resource control (Radio Resource Control, RRC) connection failure, which is not limited by this application. The terminal device needs to enter a connection state, i.e. RRC connection state, typically after selecting/reselecting a camping cell or entering an inactive state according to a cell downlink measurement result.

In some implementations, each of the first CEF report, the second CEF report, or the historical CEF report includes at least one of, but is not limited to:

(1) Downlink signal measurement results of the cell where the secondary connection fails;

(2) Position information of the occurrence of the connection failure;

(3) Downlink signal measurement results of adjacent cells before the failure of the secondary connection occurs;

(4) The number of times of connection failure occurs in the cell where the connection failure occurs;

(5) Random access related information;

(6) From connection establishment/restoration to the time when the network device request is received to report the CEF report.

It should be noted that this connection failure can be understood as: when a certain connection of the terminal device fails, the terminal device determines that a preset condition is met, and then the connection failure can be called as the connection failure corresponding to the connection failure meeting the preset condition.

It should be understood that the location information of the occurrence of the connection failure in item (2) in the above CEF report is the location recorded by the CEF report. For the explanation of each item in the above CEF report, reference may be made to the explanation of the existing CEF report, which is not repeated herein.

It should be understood that the second CEF report is the last recorded CEF report by the terminal device. That is, if the first CEF report is referred to as a CEF report of a current or current record of the terminal device, the second CEF report is a last recorded CEF report with respect to the first CEF report.

In some implementations, the at least one historical CEF report is any one of, but not limited to: a second CEF report; all historical CEF reports of the terminal device; one particular one of these all historical CEF reports. That is, the (1) th item in the above-mentioned preset condition may be any one of the following:

(1) The distance between the position of the terminal device and the position of the second CEF report record is greater than or equal to a distance threshold;

(2) The distance between the position of the terminal equipment and the positions reported by all the historical CEFs is larger than or equal to a distance threshold value;

(3) The distance between the location of the terminal device and the location of one particular historical CEF report is greater than or equal to a distance threshold.

It should be understood that, for case (3), the specific historical CEF report may be one CEF report specified by the terminal device among all the historical CEF reports, for example: it may be the first CEF report specified in all the historical CEF reports or the second CEF report described above, which is not limited in this application. When the specific historical CEF report is the above-described second CEF report, case (3) is equivalent to case (1).

It should be understood that the (1) and (2) items in the above preset conditions can be understood as follows from a position angle and a time angle, respectively: the terminal device starts with recording at least one historical CEF report, and records the first CEF report when it moves far enough, and does not record the first CEF report when it moves small or no movement occurs. A small distance of movement is understood here to mean that the terminal device is approximately not moved.

It should be understood that if the above-mentioned at least one historical CEF report is all historical CEF reports of the terminal device, the terminal device may be understood as: the terminal device starts with recording each historical CEF report and records the first CEF report when it moves far enough away.

In some implementations, the current time may be understood as a time when the terminal device fails to connect this time, or a time when the terminal device determines whether a preset condition is met, which is not limited in this application.

In some implementations, the distance threshold and/or the time threshold are predefined, or the distance threshold and/or the time threshold are configured by the network device to the terminal device, which is not limited in this application.

In some implementations, if the time threshold is that the network device is configured to the terminal device, the time threshold is related to the speed of the terminal device, but is not limited thereto.

It should be understood that the time threshold and the speed of the terminal device may have any of the following relationships, but are not limited thereto:

The method can be realized in a first mode: the time threshold is proportional to the speed of the terminal device.

The second implementation mode is: the time threshold value is equal to the product of the time base threshold value and the speed relation value; wherein the speed relation value is determined according to the speed of the terminal device.

Illustratively, threshold = velocity_ related parameter x threshold_basedline

Where threshold represents a time threshold, velocity_ related parameter represents a velocity relationship value, and threshold_basedline represents a time base threshold.

In some implementations, the speed relationship value is proportional to the speed of the terminal device, but is not limited thereto.

The third implementation mode is: the time threshold corresponds to a speed interval to which the speed of the terminal device belongs.

For example, the network device may divide the speed of the terminal device into a plurality of intervals, each of which may correspond to a time threshold, for example: the network device divides the speed of the terminal device into three intervals { threshold_highspeed, threshold_mediaspeed, threshold_lowspeed }, which are a low-speed interval, a medium-speed interval, and a high-speed interval, respectively. Further, the network device may determine a speed interval to which the current speed of the terminal device belongs, and determine a time threshold corresponding to the speed interval as a final time threshold.

In some implementations, the time interval is timed by a timer, but is not limited thereto.

In some implementations, the starting timing time of the timer is the recording time of the second CEF report, but is not limited thereto.

In some implementations, when the preset condition includes: when the time interval between the current time and the recording time of the second CEF report is greater than or equal to the time threshold, if the timing duration of the timer reaches the time threshold, the terminal equipment records the first CEF report.

It will be appreciated that after the terminal device enters the connected state, it may send a first CEF report to the network device. The network device may identify, according to the first CEF report, a location where uplink coverage and downlink coverage are not matched, so as to perform network optimization.

It should be appreciated that the above-described locations of uplink and downlink coverage mismatch are included in the first CEF report: location information of the connection failure occurs. The reason why uplink and downlink coverage are said to be mismatched is that: the terminal device may be affected by the limited power of the terminal device at a location where the terminal device may receive the downlink signal, and the terminal device may not be able to send the uplink signal to the network device, thereby causing mismatch between uplink and downlink coverage.

In summary, in the present application, the first CEF report is only recorded when the above-mentioned preset condition is met, i.e. the terminal device starts recording at least one historical CEF report, when it moves far enough away, whereas the first CEF report is not recorded when it moves a small distance or no movement occurs. That is, the terminal device records only one CEF report for a plurality of connection failures occurring at the same location or at approximately the same location, and records the CEF reports corresponding to the plurality of different locations for connection failures occurring at different locations, respectively. On the one hand, compared with the situation that only one CEF report is recorded in the prior art, the technical scheme can ensure that the system can not miss to record the situation of mismatching uplink and downlink coverage and corresponding positions, and further enables network optimization to be more comprehensive. On the other hand, through the technical scheme, the terminal equipment can avoid recording CEF reports at the same position or approximately the same position, so that the power consumption of the terminal equipment can be reduced, and the consumption of air interface resources can be reduced.
