example 1

[0130] This example proposes an exception handling method for obtaining system information on demand, which is applicable to all scenarios of obtaining system information on demand in New Radio (NR). Application scenarios of system messages.

[0131] This example provides an exception handling method when the maximum number of random accesses is reached or the monitoring clock times out in the process of obtaining system messages on demand.

[0132] In an example, the base station configures abnormality management parameters. The abnormality management parameters may be consistent with parameters in other random access scenarios, or an independent set of parameters may be defined for the on-demand system information request abnormality scenario. This set of abnormal management parameters is used to instruct the UE to adjust the cell residence threshold within a certain period of time after a certain number of failures, and the threshold also affects cell reselection.

example 2

[0141] Such as Figure 6 As shown, this example provides an exception handling method for obtaining system messages, including:

[0142] Step 101: UE RRC layer instructs UE MAC layer to obtain system information as required;

[0143] Step 102: UE MAC sends a request carrying a preamble (preamble) according to the mapping relationship between Msg1 and SI;

[0144] Step 103: The UE does not receive a matching RAR within the time window for receiving the RAR, specifically including: the next generation base station (gNB) does not receive the RAR or there is no matching preamble identifier in the returned RAR, where the preamble identifier can be is identification information such as the serial number of the preamble sent in step 102.

[0145] Step 104: UE MAC layer continues to send the preamble and fails to reach the maximum number of times;

[0146] Step 105: The UE MAC layer instructs the UE to send the RRC preamble up to the maximum number of times;

[0147] Step 106: The U...

example 3

[0154] like Figure 7 As shown, this example provides an exception handling method for obtaining system messages, including:

[0155] Steps 201-207: Same as steps 101-107;

[0156] Step 208: The RRC layer of the UE detects that the number of consecutive failures reaches N times, and then increases the cell residence threshold. After the threshold is increased, the UE reselects to the cell gNB2;

[0157] Step 209: UE starts to receive the system message broadcast and sent by gNB2;

[0158] Step 210: UE RRC instructs UE MAC to initiate a process of obtaining system information on demand;

[0159] Step 211: UE initiates a new round of on-demand acquisition of system information on gNB2;

[0160] Step 212: The UE continues to execute the process of acquiring system information on demand on gNB2.

Abstract

The embodiment of the invention discloses a method of processing of abnormal obtaining of a system message, user equipment and a storage medium. The method of processing of abnormal obtaining of a system message applied in the user equipment (UE) comprises the steps of: when the number of times of failure of obtaining the system message reaches the predetermined number of times by employing randomaccess and when the number of times of failure of obtaining the system message reaches the first predetermined number of times by employing the random access, reducing the resident priority of the cell where the UE is resident; and employing the reduced resident priority to perform cell reselection.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an exception handling method for acquiring system messages, user equipment and a storage medium. Background technique [0002] In the fifth generation (5G), the system information packets issued by the base station are divided into basic minimum system information (Minimum System Information, MSI) and other system information (Other System Information, OSI) other than the minimum system information. The MSI includes only the information required by the UE for initially accessing the cell. The terminal may also be referred to as user equipment (User Equipment, UE) and subsequently request the required OSI from the base station through the first message (Msg1) or the third message (Msg3) in the random access process according to its needs. In this way, the base station will send the OSI requested by the UE in the corresponding subframe after receiving the Ms...
