Problems solved by technology

[0022] The purpose of the present invention is to provide a method for improving the state transition speed of the user equipment, so as to overcome the need to reselect the SCCPCH to establish the corresponding channel when the UE switches between the CELL_PCH state and the CELL_FACH state in the prior art, which makes the internal signaling processing of the UE complex and cumbersome. The shortcoming of long time simplifies UE internal signaling processing and improves the transition rate of UE between CELL_PCH and CELL_FACH states

Embodiment Construction

[0037]The core of the present invention is that when the UE transitions from the CELL_FACH state to the CELL_PCH / URA_PCH state, the UE RRC does not delete the FACH / RACH public transport channel of the MAC and physical layer, nor deletes the physical layer PRACH / SCCPCH public physical channel, and only needs to indicate The physical layer cannot use the FACH channel now, and at the same time indicates that RLC and PDCP have entered the CELL_PCH / URA_PCH state at this time, and cannot send data. In this way, each protocol entity of the UE enters a state where it cannot send data or receive FACH data, achieving consistency. After entering the CELL_PCH state, if there is PS (packet switched) domain service transmission, other signaling transmission or the network side notifies the UE to leave the CELL_PCH state through paging, then RRC starts the operation of leaving the CELL_PCH state and entering the CELL_FACH state. This operation only It is only necessary to instruct RLC and PD...

Abstract

The invention relates to a method for improving the state transition speed of user device. Wherein, it comprises: when the user device receives the wireless load reset complete message sent by the network, at the condition that region is forward accessed into channel CELL_FACH state, to send message to the layer-2 protocol solid and the physical layer, to instruct it into the region paging channel CELL_PCH state; the layer-2 protocol solid and physical layer process relative operations, to make the user device enter into CELL_PCH state; when the user device receives the paging message that needed sending number from the network or itself trigger region refresh, to send message to the physical layer and the layer-2 protocol solid, to instruct it into CELL_FACH state; and the layer-2 protocol solid and physical layer process relative operations, to make user device enter into CELL_PCH state and start the region refresh process. With said invention, the internal signal process of user device can be simplified to improve the transition speed.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for improving the state transition speed of user equipment. Background technique [0002] In a mobile communication system, UE (User Equipment) has two basic operating modes: idle mode and connected mode. The UE stays in the idle mode when it is powered on, and through the non-access stratum identification such as IMSI (International Mobile Subscriber Identity), TMSI (Temporary Subscriber Identity) or P-TMSI (Packet TemporaryMobile Subscriber Identity, packet temporary mobile subscriber identity), etc. signs to distinguish. UTRAN (Terrestrial Radio Access Network) does not store the information of UEs in idle mode, and can only page all UEs in a cell or all UEs at the same paging time. When the UE completes RRC (Radio Resource Control) connection establishment, the UE transitions from idle mode to connected mode. In the RRC connection mode of the UE, ther...
