Problems solved by technology

Since different wireless networks have different coverage construction, tariffs, and quality of service (QOS), when a user uses a wireless network to make a call, if the user leaves the coverage of the current wireless network during the call, or wants to switch to another wireless network network, the call will be interrupted

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 1 , which shows a flow chart of a preferred embodiment 1 of a seamless call switching method of the present invention, including steps:

[0039] Step 101 , the first mobile terminal establishes a first VOIP call with the second terminal through the initial wireless network, and proceeds to step 102 .

[0040] The method for call seamless switching in the embodiment of the present invention is executed on a mobile terminal, and the mobile terminal may be a mobile phone. In the prior art, a VOIP call can be established between a mobile phone and a mobile phone, between a mobile phone and a landline, between a mobile phone and a computer through a wireless network and an IP core network. In order to save space, t...

Abstract

The invention discloses a call seamless shifting method and a movable terminal applied to a VOIP call. The method comprises the steps as follows: a first movable terminal establishes a first VOIP call with a second terminal by an initial wireless network; when the first movable terminal detects the occurrence of the shifting event, the first movable terminal gains a target wireless network; the first movable terminal sends a second call request to the second terminal by the target wireless network and protects the continuity of the first VOIP call; after the first movable terminal receives the confirm information of the second terminal on the second call request, a second VOIP call is established with the second terminal by the target wireless network; furthermore, after the second VOIP call is established, the first VOIP call is ended. Therefore, the seamless free shifting of the VOIP call is realized, and the call quality of the subscriber is improved.

Description

technical field [0001] The invention mainly relates to the field of communication, in particular to a seamless switching method and a mobile terminal in VOIP calls. Background technique [0002] Voice Over IP (Voice Over IP, VOIP) is a packetized and digital transmission technology based on Internet Protocol (IP) technology. The basic principle of VOIP is: compress and code the voice through the voice compression algorithm, then package the voice data according to IP and other related protocols, transmit the data packets to the destination through the IP network, and then string these voice data packets together, After decoding and decompressing, it returns to the original voice signal, so as to achieve the purpose of transmitting voice through the IP network. [0003] The IP telephone system converts the analog signal of an ordinary telephone into an IP data packet that can be connected to the Internet by a computer, and at the same time converts the received IP data packe...
