Embodiment 1

[0030] Taking the CDMA EV-DO (Code Division Multiple Access Evolution-Data only) system as an example, figure 2 Shown is a two-wave networking scenario, including two carrier frequencies F1 and F2. Assuming that we want to connect DO version 0 terminal terminals to F1 frequency point and connect DO A version terminal terminals to F2 frequency point, the preset corresponding relationship between access terminal version and carrier frequency priority is: F1 frequency point Priority access to DO 0 version terminals, F2 frequency point priority access to DO A version terminals. The above corresponding relationship can be expressed in the form of Table 1:

[0031] terminal version type

Priority access to carrier frequency

DO 0

F1

DO A

F2

[0032] Table 1

[0033] Table 1 shows the corresponding relationship between the version of the access terminal and the priority of the carrier frequency. The above relationship will be stored in th...

Embodiment 2

[0054] This embodiment will introduce a method for selecting a carrier frequency for an access terminal according to the access version terminal in a CDMA 1x system. For the method flow, refer to Figure 5 As shown, specifically, the following steps may be included:

[0055] S501. The AT sends an Origination Message (origination message) to the AN on the access channel of the air interface. The message carries a version field, which can identify whether the AT is version 95 or version 2000.

[0056] S502. The AN selects an access carrier frequency for the AT according to the version of the AT, and transmits the selected carrier frequency by sending a Channel Assignment Message (channel assignment message) or an Extended Channel Assignment Message (extended channel assignment message) on the paging channel. The frequency is assigned to the AT.

[0057] S503. The AT sends a Traffic Channel preamble (traffic channel preamble) to the AN on the specified carrier frequency, informi...

Abstract

The implementation of the invention discloses a method, device and system for selecting access carrier frequency. The method for selecting access carrier frequency includes the steps of acquiring version information of access terminal and selecting carrier frequency corresponding to the version information of access terminal as the access frequency of the access terminal according to preset correspondence of the version information of terminal and carrier frequency superiority. The system for selecting access carrier frequency comprises a network side device and an access terminal; the network side device is used for acquiring the version information of the access terminal; carrier frequency corresponding to the version information of the access terminal is selected according to preset correspondence of the version information of terminal and carrier frequency superiority; and the access terminal is used for accessing the carrier frequency assigned by the network side device according to an assignment message sent by the network side device. The technical scheme can avoid that terminals in different versions are coexisted in the same access carrier frequency, thus improving throughout of carrier frequency and improving experience of terminal user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for selecting an access carrier frequency. Background technique [0002] With the promotion of wireless network applications, multi-frequency point networking technology is gradually becoming popular. Among them, how to schedule and allocate traffic between multiple frequency points is one of the key problems to be solved in the multi-frequency point networking technology. [0003] At present, there are multiple versions of an AT (Access Terminal, access terminal) of a multi-frequency point network. Higher versions of terminals can support higher data rates and more complete scheduling mechanisms, bringing better experience to users. However, in the current multi-frequency point network, it is common for terminals of different versions to access the same carrier frequency. As the number of access terminals of lower versions increases, ...
