Description
Technical field
The present invention relates to code division multiple access (CDMA, Code Division Multiple Access) terminal technology, refer to especially a kind of CDMA20001x of having and CDMA20001x-EV-DO mixed mode function portable terminal emitter and realize the signal method for transmitting.
Background technology
CDMA2000 is the next-generation technology of narrowband CDMA, and according to different technology implementation procedures, CDMA2000 is divided into two technological phases, and the phase I is called CDMA20001x Radio Transmission Technology (CDMA20001xRTT), abbreviates CDMA20001x as; Second stage is divided into CDMA20003xRTT, CDMA20001xEV-DO and three kinds of modes of CDMA20001xEV-DV again.Wherein, 1x refers to that the frequency bandwidth of the frequency bandwidth of CDMA2000 and narrowband CDMA is the same among the CDMA20001x, also is 1.25MHz.CDMA20001x has realized backward compatible to narrowband CDMA.
The CDMA20001xEV-DO system configuration can be regarded the new wireless network part that superposeed as in the CDMA20001x system.Wherein, the 1x system is responsible for providing voice service and middle low-speed data service, and the 1xEV-DO system only is responsible for transmitting high-speed packet data service.In addition, use different carrier frequency transport services, can be optimized respectively at voice with at the business of HRPD (high rate packet data) like this, to reach best separately performance in 1xEV-DO system and 1x system.
Include the terminal (being also referred to as the terminal with mixed mode) of the structure of 1xEV-DO system and 1x system, present existence form is the portable terminal with function of surfing the Net.Defective based on the terminal that has mixed mode now is, when 1x EV-DO system is in communication (Traffic) state, if the 1x system carries out any type of firing operation, the network speed of 1x EV-DO system can be affected, and this influence is when high-speed mobile, because the switching between the base station will inevitably take place.
