Embodiment

The present invention is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to figure 5, this figure is the block diagram of CDMA wireless net card terminal device of the present invention, and this terminal installation comprises radio access module 5, main processing block 1, memory module 2, voice interface module 3 and to the interface module 4 of PC.

The radio access module 5 of this device can be finished the access of 1x wireless network and EVDO wireless network signal, and the air interface at the antenna place of this radio access module 5 satisfies CDMA access system 2000-1xEVDO standard, and backward compatible IS95.

The memory module 2 of this device is used to deposit program in machine code, and operation code, storehouse, memory pool etc. in addition, also can carry out storage of subscriber data, as the storage of yellow pages, calibration data, network interface card configuration information etc.

The voice interface module 3 of this device can external earphone etc. equipment, wait other modules to finish voice call function jointly with voice service processing module 3 in the main processing block 1.

Interface module 4 to PC can realize this device and personal computer, and particularly notebook computer connects, thereby realizes the high-speed data exchange between this device and the computer.

The main processing block 1 of this device comprises control handover module 11, timesharing scheduler module 12,1x protocol process module 13, EVDO protocol process module 14 and application processing module 15, timesharing scheduler module 12 links to each other with control handover module 11,1x protocol process module 13, EVDO protocol process module 14 respectively, and application processing module 15 comprises voice service processing module 151, data service processing module 152 and other processing modules 153.This main processing block 1 can be used for finishing the application processing relevant with the EVDO network of the protocol processes of 1x network data and EVDO network data and 1x network, the spread spectrum/despreading of data, modulating/demodulating, functions such as encoding and decoding.

When radio access module 5 searches when having only the 1x network to exist, control handover module 11 just switches to 1x network work pattern to this dual-mode device, allows this device be operated under the 1x network schemer, realizes the data function or the phonetic function of 1x network; When radio access module 5 searches when having only the EVDO network to exist, control handover module 11 just switches to EVDO network work pattern to this dual-mode device, allows this device be operated under the EVDO network schemer, realizes the data function in the EVDO network; When 1x network and EVDO network exist simultaneously (system's mixed networking), control handover module 11 and timesharing scheduler module 12 are coordinated this device work simultaneously, this terminal installation can be realized in the 1x network time-sharing multiplex of data function in the phonetic function and EVDO network, thereby realizes support voice and data function simultaneously.The specific implementation method is: the 1x network uses different carrier waves, 1x network carriers carry voice traffic, EVDO network carriers bearing data service with the EVDO network.When carrying out the EVDO data service, radio access module 5 can be locked on the carrier frequency of EVDO network, timesharing scheduler module 12 can notify radio access module 5 to go to scan the paging channel of 1x network at set intervals, when receiving the information of the discovery 1x ICQ message that radio access module 5 returns, notice control handover module 11 switches to the 1x speech business from the EVDO data service, begin to carry out the 1x voice protocol, radio access module 5 carrier frequency switch on the voice carrier frequency of 1x simultaneously, the carrier frequency of EVDO network enters hibernation (hibernate) state, thereby change the voice carrier frequency over to, be used to carry out speech business.When the 1x speech business finished, timesharing scheduler module 12 notice control handover modules 11 switched to the EVDO data service from the 1x speech business.The rule that timesharing is switched and scheduling is adopted is the preferential modes of voice, and is stronger because speech business requires for real-time, and data service is stronger for reliability requirement, a little less than requiring for real-time.Thereby realized the time-sharing multiplex of 1x speech data and EVDO data service.

This device is a dual-mode wireless network interface card terminal installation of supporting 1x network and EVDO network, and it can support voice service function and data, services function, especially when 1x network and EVDO network were simultaneous, it can realize support voice and data function simultaneously.When mixed networking, promptly under the condition that 1x network and EVDO network cover simultaneously, the user can use this wireless network card device, when enjoying a trip to the Internet on computers, freely connects and makes a phone call.
