Problems solved by technology

like figure 1 As shown, at present, there are many types of access terminals in the market, but due to volume limitations, it is impossible to design a digital dial pad and handset in its structure. Therefore, the support for CS voice services is realized by connecting a fixed telephone 2 through the RG11 interface. CS voice service between fixed phone 2 and terminal 4
The dependence on the external fixed phone 2 greatly affects its portability and limits the support of such products for CS voice services

Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] refer to figure 2 , image 3 , an embodiment of a method for implementing CS voice by a wireless mobile broadband access terminal in the present invention is proposed. figure 1 Shown is the system architecture diagram of this embodiment, and this embodiment is based on the following conditions:

[0041] (1) At present, almost all terminals such as PCs 5 and mobile phones support multimedia functions and have audio collection and playback functions. Therefore, the audio equipment on such terminals can be used to complete the support of the access terminal 3 for CS voice services. The following uses the PC 5 as an example for illustration, but this embodiment is also suitable for a terminal that has audio collection and playback functions and can establish a connection with the access terminal 3 at the same ti...

Abstract

The invention discloses a method for realizing CS (circuit switched) voice at access terminal of wireless mobile broadband. The method includes: when a signal for triggering a call is received, a transmitting a calling request to the access terminal of the wireless mobile broadband to enable the access terminal to be called; or when an incoming call message is received by the access terminal, answering an incoming call according to selection of a user; when the call gets through, acquiring audio signals; coding the acquired audio signals into voice data; and transmitting the voice data to the access terminal via a wireless network so as to enable the access terminal to transmit the voice data to a called terminal. The invention further provides a corresponding device. By the aid of the method and the device for realizing CS voice at the access terminal of the wireless mobile broadband, support to CS voice business is realized at the portable access terminal.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a method, device and system for realizing CS voice by a wireless mobile broadband access terminal. Background technique [0002] Wireless communication is undoubtedly the fastest-growing part of the communication field. With the rapid development of mobile broadband networks and the popularization of smart terminals, the growth point of wireless communication has gradually shifted from simple data services to mobile Internet with broadband multimedia services as the core. . On this basis, portable wireless mobile broadband access terminals supporting mobile broadband networks are gaining popularity rapidly. This type of portable access terminal accesses the wireless mobile broadband of the operator in the uplink, and provides Wi-Fi coverage in the downlink. Terminals such as PCs and mobile phones can complete access through their own Wi-Fi clients. The product is small in s...
