Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0049] The first embodiment of the present invention relates to a hand-held terminal (such as a mobile phone) intercom method, and its specific flow chart is as follows figure 2 shown.

[0050] In step 201, before initiating the voice intercom, the calling mobile phone sends all voice codec methods supported by the mobile phone to the called mobile phone via SMS, and agrees with the called mobile phone on the voice codec methods used in the intercom process.

[0051] In step 202, the called mobile phone selects one of the received voice codec methods supported by the mobile phone, and sends the selected result to the calling mobile phone through a short message to complete the agreement.

[0052] In step 203 and step 204, the calling mob...

Abstract

The invention discloses a hand-held terminal intercommunication method and a hand-held terminal having an intercommunication function, wherein a caller and a callee make an appointment of coding and decoding in advance, so that in a calling process a network side does not have to start two operations of voice coding and decoding, steps of middle coding and decoding of voice data are reduced in the intercommunication process, and damage to voice caused by coding and decoding is avoided at the network side, voice communication quality is improved, and time delay in a voice transmission process can be reduced partially. Moreover, business data (voice data) is transmitted on a signaling channel, and a communication to a counter part can be established rapidly by a signaling channel, such that the method avoid efficiently time loss due to frequent connection and disconnection of a business channel to reduce a calling delay.

Description

technical field [0001] The invention relates to a walkie-talkie technology, in particular to a mobile phone walkie-talkie technology. Background technique [0002] As the use of mobile phones becomes more and more popular, there are more and more mobile phones of various models and styles. However, for some users, the caller is often fixed, and the actual distance between the caller is not too far. It’s just that face-to-face communication is difficult due to other factors. If you still use a mobile phone to make calls at this time, due to the frequent calls, the corresponding costs will be increased; while using communication tools such as walkie-talkies, you must carry some additional communication tools, causing certain Inconvenience. For some people who adopt both mobile phone communication and walkie-talkie communication, they often need to carry both mobile phone and walkie-talkie, which is very inconvenient. Moreover, there are often differences in the operation of t...
