RADIO RESOURCE CONTROL RRC REESTABLISHMENT METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17966524 titled 'RADIO RESOURCE CONTROL RRC REESTABLISHMENT METHOD AND APPARATUS
Simplified Explanation
The present disclosure is about methods and apparatuses for radio resource control (RRC) reestablishment. In one example method, a terminal device selects a target cell that supports an expected network slice. The terminal device then sends an RRC reestablishment request message using the target cell. The expected network slice can be a network slice that the terminal device wants to access or a network slice corresponding to a PDU session established by the terminal device using its last serving access network device. The terminal device selects the target cell within a preset time period, starting a first timer when it begins selecting the target cell and selecting the target cell during the running of the first timer. The first timer can be specific to one or more network slices or all network slices.
- Terminal device selects a target cell that supports an expected network slice
- Terminal device sends an RRC reestablishment request message using the target cell
- Expected network slice can be the desired network slice or the network slice corresponding to a previous PDU session
- Terminal device selects the target cell within a preset time period
- First timer is started when the terminal device begins selecting the target cell
- Terminal device selects the target cell during the running of the first timer
- First timer can be specific to one or more network slices or all network slices

Original Abstract Submitted
The present disclosure relates to radio resource control (RRC) reestablishment methods and apparatuses. In one example method, a terminal device selects a target cell, where the target cell supports an expected network slice. The terminal device sends an RRC reestablishment request message by using the target cell. The expected network slice may include a network slice that the terminal device expects to access, or a network slice corresponding to a PDU session established by the terminal device by using a last serving access network device of the terminal device. The terminal device may select the target cell within a preset time period. For example, the terminal device starts a first timer when the terminal device starts selecting the target cell, and selects the target cell during running of the first timer. The first timer may be specific to one or more network slices or all network slices.
