Embodiment Construction
[0054] The present invention provides a wireless access network architecture and a method for realizing lossless migration of real-time services. The core of the present invention is that the distributed E_RLC protocol is used to replace UE context transfer, which simplifies the migration process.
[0055] The wireless access network architecture proposed by the present invention is a new two-layer node network architecture. This architecture redesigns the functions of ERS and IAGW of the existing two-layer node network architecture. details as follows:
[0056] The air interface protocol stack in ERS has evolved from the original MAC / RLC / PDCP to E-MAC (extended MAC) / distributed E-RLC (extended RLC), where E-MAC retains the original MAC layer functions. For data services carried in AM (Answer Mode) mode, the distributed E-RLC inherits the original ARQ (Automatic Repeat Request) function of the RLC layer to perform buffering and retransmission mechanisms to ensure the sequenti...
