Therefore, 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 using a communication system such as a wired and wireless communication system and a satellite-based communication system that transmits data via frames or packets.

A communication system in which a mobile terminal according to the present invention can be operated will now be described with reference to FIG.

Such communication systems may use different air interfaces and/or physical layers. For example, air interfaces used by communication systems include, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (particularly, LTE), GSM, etc. Wait. As a 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, a CDMA wireless communication system can include a plurality of mobile terminals 100, a plurality of base stations (BS) 270, a base station controller (BSC) 275, and a mobile switching center (MSC) 280. The MSC 280 is configured to interface with a public switched telephone network (PSTN) 290. The MSC 280 is also configured to interface with a BSC 275 that can be coupled to the BS 270 via a backhaul line. The backhaul line can be constructed in accordance with any of a number of known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. It will be appreciated that the system as shown in FIG. 2 can include multiple BSCs 275.

Each BS 270 can serve one or more partitions (or regions), each of which is covered by a multi-directional antenna or an antenna directed to a particular direction radially away from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 can be configured to support multiple Frequency allocation, and each frequency allocation has a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of partitioning and frequency allocation can be referred to as a CDMA channel. BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" can be used to generally refer to a single BSC 275 and at least one BS 270. A base station can also be referred to as a "cell station." Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cellular stations.

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 Figure 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 helps locate at least one of the plurality of mobile terminals 100.

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

As a typical operation of a wireless communication system, BS 270 receives reverse link signals from various mobile terminals 100. Mobile terminal 100 typically participates in calls, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within a particular BS 270. The obtained data is forwarded to the relevant BSC 275. The BSC provides call resource allocation and coordinated mobility management functions including a soft handoff procedure between the BSs 270. The BSC 275 also routes the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, PSTN 290 interfaces with MSC 280, which forms an interface with BSC 275, and BSC 275 controls BS 270 accordingly to transmit forward link signals to mobile terminal 100.

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

Embodiment 1

Referring to FIG. 3, a method for a terminal to switch a network according to an embodiment of the present invention is provided. The method may include:

S301: When the terminal receives the handover instruction sent by the network, acquiring the terminal state information of the terminal itself;

S302: The terminal determines the mapping relationship between the historical statistical status of the terminal and the state of the terminal accessing the network according to the terminal status information and the measured status information of the current various standard networks, and determines the terminal switching network.

It should be noted that the status information of each standard network specifically includes: the signal strength of each standard network currently covering the terminal. For example, the network format may include LTE, WCDMA, GSM, CDMA, WIFI, and the like. Therefore, the LTE signal strength information includes: Received Signal Strength Indication (RSSI), Reference Signal Received Quality (RSRQ, Reference Signal Receiving Quality), Reference Signal Receiving Power (RSRP), and Signal to Noise Ratio (SNR). , Signal Noise Ratio); WCDMA signal strength statistics include: Received Signal Code Power (RSCP), the ratio of the power per modulation bit to the noise spectral density (Ec/No, Ratio of energy per modulating bit to the noise) Spectral density); GSM signal strength statistics include: RSSI; WIFI signal strength statistics include: RSSI.

During the implementation of the specific network handover, the network side sends a handover command to the terminal, so that the terminal switches from the current network to the network to be switched. However, when the terminal is in a considerable number of scenarios, the network quality of the network to be switched does not bring a better data transmission rate to the terminal than the current network. For example, the current terminal works in a mobile communication network of the LTE standard, but when the signal strength of the LTE network is weakened to satisfy the handover condition from LTE to WCDMA, the data service performance of the terminal in the LTE network is actually better than WCDMA. At this time, for the terminal, It is the best choice to continue to be in the current LTE network. For example, according to statistical information, LTE reference signal receiving power (RSRP, Reference Signal Receiving Power) is in the range of -95db to -110db, and the signal-to-noise ratio (SNR) interference is small, the data performance is still better than WCDMA. When the received signal code power (RSCP, Received Signal Code Power) is -80db, the data performance is better. Although the handover condition of LTE handover to WCDMA is satisfied at this time, the WCDMA network cannot provide better data service performance for the terminal than the LTE network.

In addition, when the user is in a situation where the signal of each system is weak, for example, when the user is on a high-speed train or a public toilet in a building, the signal quality of each system is weak at this time, and the terminal will Frequent switching under different standards of the network. However, since each standard network cannot provide better data service performance, frequent handover cannot improve the data service processing performance of the terminal. Therefore, there is no need for the current terminal. The network at the switch is switched.

In addition to the above two specific cases, the terminal is in many other states, and does not need to switch the current network, but the base station only performs the switching command according to the constant threshold indicator of the related network coverage such as the signal strength. It is impossible to determine whether or not to switch to the actual situation of the terminal. Therefore, for the technical solution shown in FIG. 1, after receiving the handover command sent by the network side, the terminal actively makes a decision on the terminal handover network according to its own terminal state, and does not passively receive the handover instruction to perform handover. Therefore, the technical solution shown in FIG. 1 can prevent the terminal from passively performing network switching according to the switching instruction when the switching instruction is frequently sent by the network side, thereby reducing the amount of power consumed by the terminal when used for network switching.

Illustratively, in the embodiment, the acquiring the terminal status information of the terminal itself includes:

The terminal acquires current location information of the user through a positioning system such as a GPS; and/or,

The terminal acquires current state of motion information by sensors such as an acceleration sensor and a horizontal gyroscope.

It can be understood that the foregoing location information and motion state information can all indicate the current state of the terminal, and in addition to the above two types of information, those skilled in the art can obtain other types of information for characterizing the state of the terminal. This embodiment does not describe this.

Correspondingly, in the mapping relationship between the historical statistical state of the terminal and the state of the terminal accessing the network, the historical statistical state of the terminal may also be a historical statistical value of the location information and the motion state information.

Therefore, for the above location information, optionally, referring to FIG. 4, the embodiment of the present invention may further include:

S401: The terminal periodically collects historical location information of the terminal by using a GPS according to a preset activation frequency.

S402: When collecting the historical location information of the terminal, the terminal acquires a first historical state of each standard network covering the terminal.

S403: The terminal acquires a historical state of the first access network corresponding to the terminal according to the first historical state of each system network.

S404: The terminal constructs historical location information, a first mapping relationship between a first historical state of each standard network and a historical state of the first access network.

In a specific implementation process, the terminal may periodically call the GPS to acquire the historical location information according to the preset activation frequency, and periodically record the historical location information into an active trajectory map; while collecting the historical location information of the terminal, the active trajectory Obtaining a first historical state of each system network covering the terminal, for example, signal strength information of the network, and acquiring a state of the terminal accessing the network according to the first historical state of each system network; thereby constructing historical location information, A first mapping relationship between a first historical state of each standard network and a historical state of a corresponding terminal access network.

Therefore, when the location where the terminal is currently located is at a certain position in the historical motion track, the terminal can determine the state information of the current various standard networks and the first mapping relationship according to the measurement. Determine whether the terminal performs switching.

S704: The terminal constructs a historical motion vector, a second mapping relationship between a second historical signal strength of each standard network and a historical state of the second access network;

It should be noted that the foregoing is a process of setting a second mapping relationship for the terminal, so that the terminal can subsequently decide whether to switch the terminal according to the current motion vector and the second mapping relationship.

S705: Acquire a current motion vector of the terminal when the terminal receives the handover instruction sent by the network side;

S706: The terminal matches the second mapping relationship according to the current motion vector of the terminal and the measured signal strength of the current various standard networks, and makes a decision on the terminal switching network.

For example, the second mapping relationship of the terminal obtained through steps S701 to S704 can be expressed. Therefore, when the current motion speed of the terminal exceeds 80 km/s, the terminal maintains the existing network access status regardless of the strength of each system network covering the terminal, and does not perform handover. Therefore, when the terminal receives the handover instruction sent by the network side, the current motion vector of the acquisition terminal is described as the current motion speed of the terminal is 100 km/s, so the signal strength and the second mapping of the current various standard networks are obtained according to the measurement.
