Embodiment Construction

[0026] The method for selecting a call by a communication terminal in call waiting in the present invention will be described below with reference to the accompanying drawings and taking mobile communication as an example. At this time, the communication terminal is a mobile station (Mobile Station, MS for short).

[0027] The present invention sets a delete operation code on the first communication terminal, and the delete operation code includes an operation code such as 1 for deleting a call terminal and an operation code for deleting a waiting or held terminal such as 2, wherein the operation code for deleting a call terminal is used to indicate to delete the call terminal The communication terminal, delete waiting or held terminal operation code is used to instruct to delete the communication terminal in waiting state or held state.

[0028] Such as figure 2 , 3 As shown, when the first communication terminal MS11 talks with the second communication terminal MS12, the t...

Abstract

The method comprises: when a first communication terminal is in communication with a second communication terminal, a third communication terminal initiates a call to the first communication terminal and the first communication terminal enters a call waiting states; in the call waiting state, the first communication terminal sends a preset operation-deleting code to the switch center, and according to the received operation-deleting code the switch center disables the call connection between the firs communication terminal and the second communication terminal or the third communication terminal.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method for selecting a call by a communication terminal during call waiting. Background technique [0002] At present, the call waiting service has been widely used in fixed communication and mobile communication. The so-called call waiting service refers to the service that the communication terminal can accept a third-party call during a call without hanging up the original call, and can freely switch between two calls. . The communication terminal may be a fixed terminal or a mobile terminal. [0003] Taking mobile communication as an example (at this time, the communication terminal is a mobile station (Mobile Station, referred to as MS)), such as figure 1 As shown, during the conversation between the first terminal A and the second terminal B, the third terminal C calls the first terminal A, that is, triggers the call waiting service of the first termin...
