Description

technical field

Background technique

In the New Radio (NR) system, when a terminal device needs to enter the connection state, the terminal device initiates a connection to the network device by performing a random process. However, if there is a mismatch between uplink and downlink coverage in the cell where the terminal device resides, the terminal device cannot successfully send the message (Message, Msg) 1 and/or Msg3 to the network device, resulting in the terminal device being unable to enter the connected state. In this case, the terminal device needs to record a Connection Establishment Failure (CEF) report.

At present, during the mobile process of the terminal device, if the terminal device has experienced multiple connection failures in a row, the terminal device only records one CEF report, which mainly records the specific situation of the last connection failure, and the last connection failure of the terminal device.

The current method of only recording one CEF report may cause the system to omit to record some situations where the uplink and downlink coverage do not match and the corresponding locations, resulting in insufficient network optimization.

The small cell here may include: Metro cell, Micro cell, Pico cell cell), Femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

Before introducing the technical solution of this application, the relevant knowledge of this application is described below:

CEF report:

After the terminal device selects/reselects the cell to reside on or enters the inactive state according to the downlink measurement results of the cell, when the terminal device needs to enter the connection state, the terminal device initiates a connection to the network device through a random process. However, if there is a mismatch between uplink and downlink coverage in the residential cell of the terminal device, the terminal device cannot successfully send Msg1 and/or Msg3 to the network device, resulting in the terminal device being unable to enter the connected state. In this case, the terminal device The connection CEF report needs to be logged. At present, during the mobile process of the terminal device, if the terminal device has experienced multiple connection failures in a row, the terminal device only records one CEF report, which mainly records the specific situation of the last connection failure, and the last connection failure of the terminal device. The number of connection failures of the cell where the connection failure occurs, etc.

Exemplarily, the components of ASN.1 reported by CEF are as follows (according to TS.38.331):

It can be seen that the CEF report includes the following:

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

(2) The location information of the last connection failure;

(3) The downlink signal measurement results of neighboring cells before the last connection failure;

(4) The number of connection failures that occurred in the cell where the last connection failure occurred;

(5) random access related information;

(6) The time from connection establishment/restoration to receiving a request from a network device to report a CEF.

Further, after the terminal device enters the connected state, the terminal device can send the CEF report to the network device, so that the network device can identify the location where the uplink and downlink coverage do not match, and then perform network optimization. The current method of only recording one CEF report may cause the system to omit to record some situations where the uplink and downlink coverage do not match, resulting in insufficient network optimization. However, if the terminal device experiences multiple connection failures in a row, and the terminal device records a CEF report each time the connection fails, this will lead to excessive power consumption of the terminal device and excessive consumption of air interface resources. Therefore, how to select and record the CEF report more reasonably is a technical problem to be solved urgently in this application.

In this application, the terminal device only records one CEF report for multiple connection failures occurring at the same location or near the same location, and for connection failures occurring at different locations, the terminal device must record these multiple different CEF reports respectively. The location corresponds to the CEF report. On the one hand, it can ensure that the system will not omit to record some situations where the uplink and downlink coverage do not match and the corresponding locations, thereby making network optimization 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 present application will be described in detail below:

Fig. 2 is an interaction flowchart of a wireless communication method provided by the embodiment of the present application. As shown in Fig. 2, the method includes the following steps:

S210: When the terminal device fails to connect, the terminal device judges whether the preset condition is met; wherein the preset condition includes at least one of the following: the distance between the position of the terminal device and the position recorded in at least one historical CEF report is greater than or equal to the distance Threshold; the time interval between the current time and the recording time reported by the second CEF is greater than or equal to the time threshold;

S220: If the preset condition is met, the terminal device records the first CEF report;

S230: The terminal device sends a first CEF report to the network device.

It should be understood that, in this application, a 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 in this application. Usually, after a terminal device selects/reselects a cell to reside on or enters an inactive state according to a downlink measurement result of a cell, the terminal device needs to enter a connected state, that is, an RRC connected state.

In some implementable manners, each CEF report in the first CEF report, the second CEF report, or the historical CEF report includes at least one of the following, but is not limited thereto:

(1) The downlink signal measurement result of the cell where the connection failed;

(2) The location information where the connection failure occurred;

(3) The downlink signal measurement results of neighboring cells before the connection failure occurs;

(4) The number of connection failures in the cell where the connection failure is located;

(5) random access related information;

(6) Time from connection establishment/restoration to receiving a request from a network device 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 the preset condition is met, then it can be said that the connection failure is the corresponding connection failure when the preset condition is met. .

It should be understood that the location information where the connection failure occurred in item (2) of the above CEF report is also the location recorded in 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 will not be repeated in this application.

It should be understood that the second CEF report is the last recorded CEF report of the terminal device. That is to say, if the first CEF report is called the current or current recorded CEF report of the terminal device, then the second CEF report is the last recorded CEF report relative to the first CEF report.

In some implementable manners, the at least one historical CEF report is any of the following, but not limited thereto: a second CEF report; all historical CEF reports of the terminal device; a specific historical CEF report among all the historical CEF reports. That is to say, item (1) of the above preset conditions may be any of the following:

(1) The distance between the location of the terminal device and the location recorded in the second CEF report is greater than or equal to the distance threshold;

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

(3) The distance between the location of the terminal device and the location reported by a specific historical CEF is greater than or equal to the distance threshold.

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

It should be understood that items (1) and (2) in the above preset conditions can be understood from the perspective of location and time respectively: since the terminal device records at least one historical CEF report, when it moves a sufficient distance The first CEF report is only recorded when it is far away, and on the contrary, the first CEF report is not recorded when the moving distance is small or no movement occurs. The small moving distance here can be understood as that the terminal device does not move approximately.

It should be understood that if the above at least one historical CEF report is all historical CEF reports of the terminal device, then the terminal device records at least one historical CEF report and only records the first CEF report when it moves far enough, which can be It is understood that: the terminal device starts recording each historical CEF report, and only records the first CEF report when it moves far enough.

In some implementable manners, the above current time may be understood as the time when the terminal device fails to connect this time, or the time when the terminal device judges whether the preset condition is satisfied, which is not limited in the present application.

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

In some implementable manners, if the time threshold is configured for the terminal device by the network 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:

Achievable way 1: the time threshold is proportional to the speed of the terminal device.

Realization mode 2: the time threshold is equal to the product of the time base threshold and the speed relation value; wherein, the speed relation value is determined according to the speed of the terminal device.

Exemplarily, threshold=velocity_related parameter*threshold_basedline

Among them, threshold represents the time threshold, velocity_related parameter represents the velocity relationship value, and threshold_basedline represents the time base threshold.

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

Realizable way three: the time threshold corresponds to the speed range to which the speed of the terminal device belongs.

Exemplarily, the network device may divide the speed of the terminal device into multiple intervals, each interval may correspond to a time threshold, for example: the network device divides the speed of the terminal device into three intervals {threhold_highspeed, threshold_mediumspeed, threshold_lowspeed}, which The three sections are low-speed section, medium-speed section and high-speed section. Further, the network device may determine the speed interval to which the current speed of the terminal device belongs, and determine the time threshold corresponding to the speed interval as the final time threshold.

In some implementation manners, the time interval is obtained by counting a timer, but it is not limited thereto.

In some implementation manners, the starting time of the timer is the recording time of the second CEF report, but it is not limited thereto.

In some practicable manners, when the preset condition includes: 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, at this time, if the timing duration of the timer reaches the time threshold, the terminal device Record the first CEF report.

It should be understood that, after the terminal device enters the connection state, it may send the first CEF report to the network device. Wherein, the network device may identify a location where uplink and downlink coverage do not match according to the first CEF report, and then perform network optimization.

It should be understood that the location where the uplink and downlink coverage do not match is included in the first CEF report: information about the location where the connection failure occurred. The reason why it is said that the uplink and downlink coverage do not match is that the terminal equipment may be affected by the limited power of the terminal equipment at the position where the downlink signal can be received, and the terminal equipment cannot send the uplink signal to the network equipment, resulting in uplink and downlink Coverage mismatch.

To sum up, in this application, only when the above preset conditions are met, that is, the terminal device records at least one historical CEF report since recording at least one historical CEF report, and only records the first CEF report when it moves far enough. When the distance is small or no movement occurs, the first CEF report is not recorded. That is to say, the terminal device only records one CEF report for multiple connection failures that occur at the same location or similar to the same location, and for connection failures that occur at different locations, the terminal device must record these multiple different locations Corresponding CEF report. On the one hand, compared to the case where only one CEF report is recorded in the prior art, the technical solution of the present application can ensure that the system will not omit to record some cases where the uplink and downlink coverage do not match and corresponding locations, thereby making network optimization more comprehensive. On the other hand, through the technical solution of the present application, the terminal device can avoid recording the CEF report at the same location or approximately the same location, thereby reducing the power consumption of the terminal device and the consumption of air interface resources.
