Embodiment 1

[0040] Through analysis, due to the conflict between the 3GPP 38.331 protocol and the 38.413 protocol definition in the 3GPP protocol: when the INITIAL CONTEXT SETUP REQUEST message does not configure PDU SESSION resources, the 5G-NR base station will not configure the DRB bearer when configuring SRB2 resources for the UE, which is different from 38.331 The agreement clearly requires that at least one DRB bearer must be configured when configuring the SRB2 bearer. At this time, the UE will fail to verify the parameter (SRB2 / DRB) configuration, and fail to access the NR network, resulting in a decrease in the success rate of UE network access. Therefore, this embodiment proposes a method for improving the success rate of UE accessing a 5G-NR base station. The method is: by modifying the 3GPP protocol, it is ensured that the UE must pass the verification of the SRB2 / DRB configuration during the network access process.

Embodiment 2

[0048] This embodiment implements a method for a UE to access a 5G-NR base station. The method for the UE to access a 5G-NR base station is modified based on the method for improving the success rate of UE accessing a 5G-NR base station described in Embodiment 1. The 3GPP protocol implements a UE network access process. The UE network access process combines image 3 It can be seen that it will not be repeated here.

Abstract

The invention provides a method for improving the success rate of UE accessing a 5G-NR base station. According to the method, by modifying a 3GPP, the UE is ensured to pass the verification of SRB2 / DRB configuration in a network access process. The invention also provides a method for accessing the UE to the 5G-NR base station. The method for accessing the UE to the 5G-NR base station realizes a UE network access process based on the modified 3GPP protocol in the method for improving the success rate of accessing the UE to the 5G-NR base station. According to the invention, the compatibility problem caused by parameter configuration verification failure due to protocol conflicts can be solved by modifying the 3GPP protocol, so that the success rate of accessing the commercial UE to the 5G-NR base station is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular, to a method for improving the success rate of UE accessing a 5G-NR base station and a UE network access method. Background technique [0002] The 3GPP wireless NR system protocol defines the process for commercial UEs to access 5G-NR base stations in independent networking mode. The core network, 5G-NR base station and commercial UE cooperate to realize complete access functions: [0003] (1) The UE initiates a random access request to the 5G-NR base station due to business needs (calling, surfing the Internet, being called, location update, etc.); [0004] (2) The 5G-NR base station prepares resources for random access for the UE, sends a random access response to the UE, and establishes bearer SRB0 on ​​the air interface; [0005] (3) The UE obtains a random access response, and requests the 5G-NR base station to establish an RRC connection through the RRC conn...
