Title:
METHOD AND DEVICE FOR ESTABLISHING RADIO RESOURCE CONTROL CONNECTION
Document Type and Number:
WIPO Patent Application WO/2021/072629
Kind Code:
A1
Abstract:
Provided are a method and device for establishing an RRC connection. The method comprises: a terminal device being able to use a second user identity to establish an RRC connection of the second user identity according to configuration information comprised in a first RRC message of a first user identity. A terminal device needing to use a second user identity to re-initiate random access and to independently re-establish an RRC connection is prevented, and the situation whereby the terminal device fails as a result of initiating random access by means of the second user identify can also be prevented, thereby facilitating improving the success rate of random access, and even leading to the terminal device not needing to use the second user identity to initiate random access and instead directly inheriting an RRC connection of a first user identity, so that the resource overhead caused by random access can also be avoided, thereby facilitating improving the transmission performance.
