Problems solved by technology

[0005] It can be seen from the above that the synchronous / asynchronous message transmission between the physical layer and the upper layer protocol is too frequent, so the overhead of system signaling is increased, and the efficiency of physical layer synchronization / out-of-synchronization reporting is reduced

Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Referring to FIG. 2 , a method for reporting synchronization / out-of-synchronization according to an embodiment of the present invention is briefly described. As shown in Figure 2, the reporting of the synchronization / out-of-synchronization status of the physical layer is divided into two stages. The first stage is the establishment stage of the initial synchronization, and the second stage is the stage after the initial synchronization is established. Among them, the second stage is further divided into a synchronous state and an out-of-synchronization state. If the physical layer judges that the initial synchronization condition is satisfied in the first stage, it will report the synchronization to the upper layer protocol, and then the state will transfer to the second stage of the synchronization state. In the synchron...

Abstract

The present invention discloses a synchronizing or desynchronizing state reporting method for downlinks of physical layers, which includes steps below: In an initial synchronizing phase, a physical layer judges whether initial synchronizing conditions are met and then reports synchronizing state information of downlinks to a senior layer of protocol to enter into a synchronizing state. The protocol approves downlinks to create initial synchronization according to state information reported by the physical layer. In synchronizing state, the physical layer verifies whether desynchronizing conditions are met, the physical layer reports desynchronizing state information of downlinks to the senior layer of protocol. In desynchronizing state, the physical layer verifies the synchronizing condition is satisfied and reports synchronizing state information of downlinks to the senior layer of protocol to enter into the synchronizing state. The present invention can reduce remarkably synchronizing and desynchronizing message volume reported by the physical layer, save system signaling consumption and improve system efficiency.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for reporting the synchronization or out-of-synchronization state of the physical layer downlink. Background technique [0002] At present, the WCDMA mobile phone physical layer checks the synchronization status of the downlink dedicated physical channel every 10ms wireless frame, and the synchronization / out-of-synchronization status reporting of the physical layer is divided into two stages. The first stage is the establishment of initial synchronization. If the quality of the dedicated physical control channel in the last 40 ms is better than the threshold Qin after the upper-layer protocol initiates the establishment of the dedicated physical channel, the physical layer will report the synchronization to the upper-layer protocol. After the upper-layer protocol confirms the synchronization Send a physical channel establishment confirmation to the physi...
