Problems solved by technology

For such bursty data services, using connection-based data transmission methods is not only not easy to achieve high efficiency, but also has the following disadvantages: due to the bursty nature of data, it will require frequent disassembly and construction of connections between terminals and base stations , which leads to more power consumption of the terminal and lower processing efficiency of the base station; in addition, transmitting small data packets on the high-speed data channel is also a waste of the air interface resource i

Embodiment Construction

[0074] figure 1 A flow chart of the method for selecting the access channel rate for the present invention, such as figure 1 As shown, it mainly includes:

[0075] Step 100: Negotiate between the terminal and the base station the supported access channel rate class including the support capability of the lowest rate class.

[0076] In this step, more access rate levels are introduced for the access channel. For example, the access channel is required to support the following rate levels of 2.4kbps, 4.8kbps, 9.6kbps, 19.2kbps, 38.4kbps, and 76.8kbps, a total of six rate levels. The load conditions corresponding to each access channel rate level are shown in Table 1.

Abstract

The present invention discloses a method and a system for selecting access channel rate. The method includes the following steps: a terminal negotiates with a base station about the supported access channel rate level including the lowest rate level support ability (100); the terminal selects the access channel rate between the maximal access rate and minimal access rate of the access channel levels supported by the both sides (101).The method of the present invention introduces more access rate level for the access channel, and increases the corresponding field marks, and insures the effective selection of access channel data transmission rate which meets the data transmission requirement and considers the network load.

Description

technical field [0001] The present invention relates to the access technology of the wireless communication system, in particular to a method and system for selecting access channel rate. Background technique [0002] In the wireless communication industry, at present, the enhancement of Code Division Multiple Access (CDMA, Code Division Multiple Access) technology is a hot spot in the industry. [0003] With the application of networks and terminals, CDMA technology, such as High Rate Packet Data (HRPD, also known as 1xEVDO) system, has been more and more commercially available, and various data services based on this type of bearer network are also emerging. The most typical services include ftp download, video call and so on. Compared with the original 2G or 2.5G wireless communication network, the HRPD system has higher uplink and downlink data rates and higher system capacity. Therefore, the HRPD system can bring good user experience to users using the above data servi...
