Embodiment Construction
[0051] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0052] The present invention is a method for realizing PHS base station channel data exchange and rate adaptation, that is, realizing the channel data exchange and channel rate adaptation method required by PHS base station for voice and data services through pure software, under the control of CPU , can complete the exchange and rate adaptation of the channel data between the wireless channel and the wired channel required by the base station in real time in real time.
[0053] See attached figure 1 , is a flow chart of the steps of the inventive method, and the steps for realizing the method are as follows:
[0054] Step 1: On the hardware, introduce the code stream with the information rate of the uplink channel at 32Kbps and the 64Kbps PCM code stream after the ADPCM / PCM conversion of the 32Kbps information on the uplink channel i...

The invention discloses a method and equipment for realizing channel data exchange and rate adaptation by using a programmable device, comprising: introducing the uplink 32Kbps code stream and the uplink 64Kbps code stream of the base station into the data exchange and rate adaptation unit of the base station equipment, The downlink 64Kbps code stream and the downlink 32Kbps code stream are introduced into the data exchange and rate adaptation unit; the four code streams are respectively serial / parallel converted under the control of the clock control unit, and are latched into the channel data register group according to the channel; the external The CPU selects the channel data storage unit to be output by controlling the exchange switch unit according to the service type and user channel allocation; under the control of the clock control unit, the channel data storage unit selected by the exchange switch unit passes through the parallel / serial conversion unit. line output. The invention is realized by performing software programming on the programmable device, does not use a dedicated switching chip, saves system cost, and facilitates system upgrade.
Description
technical field [0001] The present invention relates to a method and equipment for implementing channel data exchange and rate adaptation by a mobile communication wireless base station, and in particular to a wireless base station in the field of mobile communication, which realizes channel wireless side channel data and wired side channel data exchange and communication when providing voice services and data services. Method and device for rate adaptation. Background technique [0002] (1) Current situation [0003] At present, the development and popularization of mobile communication is extremely fast. The clear and cheap voice service provided by the mobile communication system is not only loved by more and more people, but also the high-speed data service volume it provides is also increasing. However, in mobile communication systems, different types of services require different channel data exchange methods and rate adaptation methods. Generally, dedicated switching...
