Abstract
Description
technical field
[0001] The invention relates to the field of communication technology, in particular to a method, system and device for realizing enhanced CELL-FACH state and CELL-DCH state transfer. Background technique
[0002] In the traditional CELL-FACH state, the terminal sends uplink data through the random access channel (Random Access Channel, RACH), receives downlink data through the forward access channel (Forward Access Channel, FACH), all state control and data The transmission is all completed through interaction with a radio network controller (Radio Network Controller, RNC).
[0003] However, in the enhanced CELL-FACH state, the base station needs to calculate the scheduling time for terminal data and process the information fed back by the terminal. Therefore, the base station needs to maintain the context information of the terminal in the enhanced CELL-FACH state. And in the prior art, the configuration parameters used when in the CELL-DCH state and the e...
