Terminal device adaptation and method for supporting terminal device adaptation, and terminal

Abstract

The invention discloses adaptation of terminal equipment as well as a method and terminal for supporting the adaptation of the terminal equipment. The method comprises the following steps: transmitting network side adaptive signals according to a calling process; receiving and detecting terminal equipment adaptive signals feedback according to the network side adaptive signals, and switching to a corresponding working pattern according to the terminal equipment type contained in the adaptive signals of the terminal equipment; receiving the network side adaptive signals, and acquiring network side adaptive requests through detecting the network side adaptive signals; and transmitting the terminal equipment adaptive signals containing the terminal equipment type according to the network side adaptive requests. In the invention, the corresponding work pattern is adapted automatically by using the adaptive signals to identify the type of the terminal equipment, the adaptation of a network side and a terminal can be finished rapidly with less occupied resources, the influence from a device, a user and the external environment can be prevented, the adaptation accuracy is higher, and the user experience is promoted further.

Description

technical field [0001] The present invention relates, in particular, to an adaptation of terminal equipment and a method for supporting the adaptation of terminal equipment and a terminal, belonging to the technical field of network communication. Background technique [0002] Traditional voice is generally called narrowband voice (Narrow Voice), and its limited voice frequency band is 4KHZ, including narrowband voice terminals (such as telephones) and network-side devices (such as switches, access devices), all of which limit the voice frequency band. At the same time, the network side equipment generally uses 8K sampling frequency to digitize the analog signal, and uses the ITU-T G.711 standard to compress the voice. The wideband voice standard expands the voice spectrum to 7KHZ, which technically requires the voice terminal and network-side equipment to be able to expand the voice spectrum to 7K. At the same time, the network-side equipment needs to use 16KHZ sampling fre...

Problems solved by technology

[0006] Due to the need to separately configure the terminal equipment docked on the network side, it requires a lot of manpower and equipment resources; and the method of judging the type of terminal equipment through a specific terminal equipment identification circuit and algorithm is affected by equipment, users and external environments. In addition, if the environmental noise of the place where the phone is used is relatively large, the output frequency bands of different phones will vary greatly, which may also cause misjudgment by the identification circuit, or the identification circuit may be misjudged at different times. Judging the different types of phones will cause frequent switching of the communication system, which will have a great impact on the call; this identification method will also have a greater impact on the called party, because the phone can only be judged after the called user picks up the phone If there is no signal output for a short time after the called party picks up the phone, the circuit cannot judge, which will cause the phone to still be unable to judge the type of the called party within a period of time after the call is established, which will have a certain impact on the call quality.
