Abstract
A context relocation method used for header compression when seamless SRNS relocation is performed in an asynchronous IMT-2000 system transmits respective SN field values of compressor context and decompressor context together with SSR information from a source RNC or a target RNC to a UE when an SRNC, which manages dedicated radio resource assigned to a user equipment, performs SSR, and therefore, transmission efficiency can be improved as well as the UE and the target RNC which became the SRNC after SSR can be synchronized with the contexts of each other after the relocation..
Claims20
A context relocation method characterized in that a source radio network controller (RNC) or a target RNC transmits seamless SRNS relocation (SSR) information and sequence number (SN) field values of compressor context and decompressor context to a user equipment (UE) when a serving radio network controller (SRNC), which manages dedicated radio resource assigned to a user equipment, performs seamless SRNS relocation (SSR).
A context relocation method comprising:
- a step of transmitting compressor context and decompressor context from a source RNC to a target RNC;
- a step of transmitting SSR information and respective SN field values of the compressor context and the decompressor context from the source RNC to a UE;
- and
- a step of updating respective SN field values of the compressor context and the decompressor context stored in the UE.
