Up to now, the mobile terminal has been described in terms of its functions. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

Example one

An embodiment of the present invention provides a handover method, as shown in fig. 3, the method may include:

s101, detecting a first network state between the first terminal and the second terminal in a first communication connection mode, and judging whether the first network state meets a switching condition, wherein the first communication connection mode is a communication connection mode in which first video information and first voice information are synchronously interacted.

The switching method provided by the embodiment of the invention is applied to the scene with poor network condition during video call.

In the embodiment of the invention, the first communication connection mode can be a video call mode, when a user carries out video call, the first video information can be displayed on a display page of the first terminal in real time, and the first voice information can be transmitted to the first terminal through a sound receiver such as an earphone in real time.

In the embodiment of the invention, when the first terminal and the second terminal carry out video call, the first terminal judges whether the current network condition meets the switching condition or not by detecting the network condition between the first terminal and the second terminal.

Optionally, in the embodiment of the present invention, the parameter for detecting the network state may be a transmission speed, a number of received packets, and the like, which is specifically selected according to an actual situation, and the embodiment of the present invention is not specifically limited.

In the embodiment of the invention, a preset time period is arranged in the first terminal, when the preset time period is reached, the first terminal acquires a value of first transmission data between the first terminal and the second terminal, and the value of the first transmission data is compared with a preset transmission threshold value; when the numerical value of the first transmission data is larger than a preset transmission threshold value, the network state between the first terminal and the second terminal is represented to be good, and the network state does not meet the switching condition; when the value of the first transmission data is smaller than the preset transmission threshold value, the network state between the current first terminal and the second terminal is represented to be poor, and the first network state at the moment meets the switching condition.

Optionally, in this embodiment of the present invention, the first terminal may initiate a first communication connection with the second terminal, and the second terminal agrees to perform the first communication connection with the first terminal; the second terminal may initiate a first communication connection with the first terminal, and the first terminal agrees to perform the first communication connection with the second terminal.

And S102, when the network state is judged to meet the switching condition, converting the first voice information into first character information, wherein the first character information is character information corresponding to the first voice information.

And the first terminal completes the operation of converting the first voice information into the first text information according to the detected network state.

In the embodiment of the present invention, when the value of the first transmission data is smaller than the preset transmission threshold, the network state difference between the current first terminal and the current second terminal is represented, and the switching condition is satisfied, at this time, the first voice information needs to be converted into the first text information.

In the embodiment of the invention, the first terminal acquires the second voice information in the preset time period according to the preset strategy, converts the second voice information into the corresponding second text information, then acquires the third voice information in the next preset time period, and completes the corresponding conversion operation.

For example, as shown in fig. 4, when a user a uses a mobile phone a to perform a video call with a user B, when poor network quality is detected, a dialog box of "whether to convert voice into text" pops up on a display page of the mobile phone a, and when the user a clicks a "confirm" button below, the mobile phone a converts the received voice into text; when the user a clicks the "cancel" button below, the mobile phone a continues the video call therebetween.

S103, displaying the first character information on a display interface.

After the first terminal converts the first voice message into the first text message, the first terminal displays the first voice message on the display interface.

In the embodiment of the invention, the first terminal reserves a preset display position for the first text information on the display interface, and after the first terminal typesets the first text information, the first text information and the first video information after typesetting are displayed at the preset position on the display interface.

For example, as shown in fig. 5, the text information displayed in the area a of the display screen of the mobile phone a is the voice information sent by the mobile phone B to the mobile phone a, and the non-area a of the display screen of the mobile phone a is the video information sent by the mobile phone B to the mobile phone a.

Further, the first terminal detects the first network state, and when the first network is judged not to meet the switching condition, the first terminal switches back to the first communication connection mode to continue to realize synchronous display of voice and video.

For example, as shown in fig. 6, when the network quality of the mobile phone a is good, the display page of the mobile phone a pops up a dialog box of "whether to convert characters into voice", and when the user a clicks the "confirm" button below, the mobile phone a performs a video call with the mobile phone B; when the user A clicks the 'cancel' button on the lower part, the mobile phone A continues to convert the received voice into characters.

It can be understood that when the first terminal and the second terminal carry out a video call, the first terminal detects the first network state, and when the first network state meets the switching condition, the first voice information is converted into the first text information, and the first text information is displayed at the preset position of the display interface, and the display effect of the first terminal is improved under the condition of poor network quality.

s201, a first communication connection is established between the first terminal and the second terminal, and a first communication connection mode is entered, wherein the first communication connection mode is a communication connection mode in which first video information and first voice information are synchronously interacted.

S202, under the first communication connection mode, the first terminal obtains first transmission data which are in communication transmission with the second terminal.

When the first terminal establishes a first communication connection with the second terminal, the first terminal acquires first transmission data when a preset time period is reached.

In the embodiment of the invention, when the first terminal and the second terminal carry out video call, the time inside the first terminal starts to be started, when the preset time period is reached, the first terminal acquires the value of the first transmission data between the first terminal and the second terminal,

s203, the first terminal detects a first network state according to the first transmission data.

After the first terminal acquires the first transmission data, the first terminal detects the first network state according to the first transmission data.

In the embodiment of the invention, the first terminal detects the first network state by detecting the size of the first transmission data in real time.

S204, the first terminal compares the first transmission data with a preset transmission threshold value.
