Embodiment Construction

[0026] In the present invention, the MAC control entity determines the MAC state transition of the user equipment according to the service volume or buffer occupancy rate measurement of the user equipment. The media access control layer of the base station and the media access control layer of the user equipment respectively maintain the MAC state of the user equipment, and the transition of the MAC state is synchronized in the above two devices. When the MAC state corresponding to the user equipment in the base station transitions, the base station notifies the user equipment to switch the MAC state through the MAC layer or physical layer control signaling; or the user equipment uses a timer to determine the corresponding MAC state transition in the base station and then controls the MAC state transition by itself .

Abstract

This invention discloses a transfer method for medfia access control state in a radio communication system including the following steps: a base station measures all PRI queue service volumes or an engross rate of the buffer region of a user device at MAC layer and enquires the MAC state of said device in the base station, if it is an active state and the service volume of all service PRI queues or the occupation rate of the buffer region are lower than set threshold and continues the set time, then the MAC state corresponding to the user device in the MAC layer is transferred to a discontinuous sending / receiving state, and the synchronous control state of the MAC of said device is transferred to the MAC discontinuous sending / receiving state, if it is the discontinuous sending / receiving state and one or the service volume of multiple service PRI quiues or the occupation rate of the buffer region is higher than the threshold value, then, the MAC state in the base station layer is transferred to the MAC active state as well as the control state, otherwise, it keeps the original one.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, in particular to a method for migrating a media access control state in a user equipment connection mode in a wireless communication system. Background technique [0002] In the third-generation mobile communication system, the user equipment (UE) can be in four states in the radio connection control (RRC) connection mode according to the service characteristics and the type of the allocated transmission channel: cell_dedicated channel state (CELL_DCH) , Cell_Forward Access Channel Status (CELL_FACH), Cell_Paging Channel Status (CELL_PCH) and Universal Terrestrial Radio Access Network (UTRAN) Registration Area_Paging Channel Status (URA_PCH), the activity of which decreases in turn. The network controls the switching of the transmission channel type and the migration between the four states through the RRC layer signaling according to the corresponding strategy, but these ope...
