Problems solved by technology

The SCCH message is sent on the idle PCH, but it cannot be prioritized over the PCH message that has not been sent
The current practice cannot guarantee that when the SCCH message traffic bursts, it will be delivered in time by borrowing the PCH

Embodiment Construction

[0017] The present invention is described in further detail below:

[0018] (1) Base station LCCH processing system

[0019] Such as image 3 As shown, the base station LCCH processing device is composed of a protocol processor and a control channel data processor.

[0020] The protocol processor completes the protocol conversion, which can be realized by CPU software. It receives the called call establishment information from the network, converts it into a paging message and sends it to the control channel data processor. When the system starts, the protocol processor initializes the BCCH message and sends it to the control channel data processor for buffering; the protocol processor receives the SCCH data from the baseband processor to record the receiving time, and performs protocol processing; 1 second minus the SCCH data processing time (SCCH The absolute time difference between the data receiving time and the current time) obtains the effective delivery duration T mi...

Abstract

The logical control channel process device in base station of wireless city phone system comprises: a protocol processor, and a control channel data processor with a command receiver, a down buffer, a calling-group processor, a buffer processor for calling information, a buffer processor for broadcast channel, and a logical control channel sending controller. This invention applies time information to label PCH and SCCH precisely for reliable sending to improve performance without adding hardware cost.

Description

technical field [0001] The invention relates to an LCCH (Logical Control Channel) processing algorithm and device of a base station in a PHS system (Personal Handyphone System, also known as a wireless local telephone system in China), which can better realize SCCH (Signalling control channel signaling) Control channel) data delivery effectively, and PCH (Paging channel paging channel) message delivery dynamic control, improve network performance. Background technique [0002] PHS base station air signal adopts TDMA / TDD (Time Division Multiple Access / Time Division Duplex, Time Division Multiple Access / Time Division Duplex) mode to work, such as figure 1 As shown, a frame every 5 milliseconds is divided into 8 time slots, 4 time slots from the downlink base station to the mobile phone, and 4 time slots from the uplink mobile phone to the base station. One of the channels is CCH ((Control channel), and the other three are TCH (Traffic channel). CCH appears every 20 cycles (10...
