Example Embodiment

[0029] Example one:

[0030] Take the CDMA EV-DO (Code Division Multiple Access Evolution-Data only, evolution data code division multiple access) system as an example, figure 2 Shown is a two-wave networking scenario, including F1 and F2 carrier frequencies. Suppose we want to connect the terminal of DO 0 version terminal to F1 frequency, and the terminal of DO A version terminal to F2 frequency, then the preset corresponding relationship between the access terminal version and the carrier frequency priority is: F1 frequency 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

[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 the AN for the terminal to query when accessing....

Example Embodiment

[0053] Embodiment two:

[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. Refer to the method flow Figure 5 As shown, the following steps can be specifically included:

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

[0056] S502. The AN selects the access carrier frequency for the AT according to the AT version, and sends the Channel Assignment Message or Extended Channel Assignment Message on the paging channel to transfer the selected carrier The frequency is assigned to AT.

[0057] S503. The AT sends a Traffic Channel preamble (traffic channel preamble) to the AN on the designated carrier frequency to inform the AN that the traffic channel has been successfully acquired.

[0058] S504: After the wireless servi...

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, ...
