2 , a CDMA wireless communication system may include a plurality of mobile terminals 100 , a plurality of base stations (BSs) 270 , a base station controller (BSC) 275 and a mobile switching center (MSC) 280 . MSC 280 is configured to interface with public switched telephone network (PSTN) 290 . MSC 280 is also configured to interface with BSC 275, which may be coupled to base station 270 via a backhaul line. The backhaul line 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 appreciated that the system as shown in FIG. 2 may include multiple BSC2750s.

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

The intersection of partitions and frequency assignments may be referred to as CDMA channels. BS 270 may also be called a base transceiver subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to refer generally to a single BSC 275 and at least one BS 270. A base station may also be referred to as a "cell site". Alternatively, each partition of a particular BS 270 may be referred to as multiple cell sites.

As shown in FIG. 2, a broadcast transmitter (BT) 295 transmits broadcast signals to mobile terminals 100 operating within the system. The broadcast receiving module 111 as shown in FIG. 1 is provided at the mobile terminal 100 to receive broadcast signals transmitted by the BT295.

The GPS module 115 as shown in FIG. 1 is generally configured to cooperate with the satellites 300 to obtain the desired positioning information. Instead of or in addition to GPS tracking technology, other technologies that can track the location of the mobile terminal may be used. Additionally, at least one GPS satellite 300 may selectively or additionally handle satellite DMB transmissions.

As a typical operation of a wireless communication system, the BS 270 receives reverse link signals from various mobile terminals 100 . Mobile terminals 100 are typically involved 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 BSC275. The BSC provides call resource allocation and coordinated mobility management functions including soft handover procedures between BSs 270. BSC 275 also routes received data to MSC 280, which provides additional routing services for interfacing with PSTN 290. Similarly, PSTN 290 interfaces with MSC 280 , which interfaces with BSC 275 , and BSC 275 controls BS 270 to send forward link signals to mobile terminal 100 accordingly.

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

Example 1

The first embodiment of the present invention proposes an intelligent network search method, as shown in FIG. 3 , including:

S101, when a terminal mobile communication network disconnection signal is received, obtain a current geographic location;

Specifically, the mobile communication network includes but is not limited to the commonly used CDMA, WCDMA, GSM, LTE, etc. The disconnection of the mobile communication network means that the mobile terminal cannot communicate with the mobile network base station, making the mobile terminal unable to communicate normally, mobile data state of use etc. Geographical location GL (Geographical location) refers to the geographic location information where the search occurs. It consists of three vectors: longitude X, latitude Y and altitude Z. The present invention includes the current address position and the historical geographic position, which are acquired by the mobile terminal through GPS satellite positioning.

S102, compare the current geographic location with the historical geographic location information database, if there is a historical geographic location whose Euclidean space distance difference from the current geographic location is less than a set threshold in the historical geographic location information database, output the historical geographic location Corresponding historical multi-mode search network list;

Specifically, the historical geographic location information database GLDB (Geographical Location Data Base) is a network search information database based on geographic location information, including the location where the mobile terminal was located when the mobile communication network was disconnected from the network and searched the network in the past or within a period of time. And the corresponding information set of search time, search network mode, and search success or not. The historical geographic location information database GLDB is stored in the memory 160 described in FIG. 1 .

For example, define the relevant data table structure in the historical geographic location information database as follows:

The NetType table defines the codes of each network mode, as follows:

The following table records the historical data of searching the network at various locations. GL indicates the geographical location of the search, State indicates whether the search is successful, 1 indicates success, 0 indicates failure, NetType indicates the network type of the search, and TimeStamp is the time when the search occurred.

Euclidean space distance, also known as Euclidean metric, is a commonly used definition of distance, which refers to the true distance between two points in m-dimensional space, or the natural length of the vector (that is, the point to distance from the origin). Euclidean distance in 2D and 3D space is the actual distance between two points. The calculation formula of Euclidean space distance is: where (x1, y1, z1) represents the historical position coordinates, (x, y, z) represents the current position coordinates,

When the mobile terminal is disconnected from the network, the coordinates of the current address location are collected, and the current geographic location is compared with the historical geographic location information database. If the historical address location that is close to the current geographical location has also been disconnected from the Internet, the search sequence of successful historical web searches will be used as the current web search sequence. Compared with the default search sequence, it is an optimized search sequence. , so the historical multimodal search network list corresponding to the historical geographic location is output.

S103: Search the web according to the historical multi-mode web search list, and if the web search is successful, save the current geographical location and the web search result in a historical geographical location information database.

After successfully searching the network according to the historical multi-mode network search list, save the information such as the location coordinates of the local network search, the network mode of the successful network search, the network search time and other information in the historical geographic location information database as a reference for subsequent network searches. .

The intelligent search method implemented above does not search the network in the order of the default network mode, but searches the network with reference to the historical network mode close to the current position when the network search is successful, which means that there is no need to first search for some current network search methods. The network mode with a high probability of location failure increases the chance of a successful network search and avoids wasting time and electricity.

Embodiment 2

The second embodiment of the present invention proposes an intelligent network search method, as shown in FIG. 4 , including:

S201, when a terminal mobile communication network disconnection signal is received, obtain a current geographic location;

S202, compare the current geographic location with the historical geographic location information database, if there is a historical geographic location whose Euclidean space distance difference from the current geographic location is less than a set threshold in the historical geographic location information database, output the historical geographic location Corresponding historical multi-mode search network list;

S203, searching the network according to the historical multi-mode search network list;

S204, determine whether the search network is successful? If successful, execute S205; if unsuccessful, execute S206;

S205, save the current geographic location and its search results in the historical geographic location information database;

S206: Calculate the network search interval according to the historical multi-mode network search list, and add the current geographic location and its search results to the historical geographic location information database.

Specifically, calculate the interval time for the next network search, and refer to the probability of historical network search failures in the current network mode. If the probability of historical network search failures is high, it means that the network in the area is very weak, and the default network search time without adjustment is used. Searching the network at intervals will bring about huge power consumption. Properly adjusting and extending the time between searching the network can reduce the power consumption of searching the network.

The intelligent network search method implemented above refers to the successful network search in historical nearby locations when searching the network, and intelligently adjusts the network search interval according to the probability of successful historical network search, effectively avoiding the problem of large power consumption caused by blindly searching the network.

Embodiment 3

S302, compare the current geographic location with the historical geographic location information database;

S303, determine whether there is a historical geographic location whose Euclidean distance from the current geographic location is less than a preset threshold? If it exists, execute S305; if not, execute S304;

S304, search the network according to the preset multi-mode network search sequence; then execute S311;

S305, searching the network according to the historical multi-mode network search list;

S306, according to the historical multi-mode network search list, count the number of successful network searches of each network mode;

S307: Determine whether the number of successful network searches in each network mode is all zero? If all are zero, execute S308; if not all are zero, execute S309;

Specifically, the number of successful network searches for each network mode is all zero, which means that the current geographical location is the first time that the network is disconnected, and the network can be searched directly according to the default network search order, for example, in the order of CDMA->LTE->GSM Do a web search.

S308, do not adjust the network search sequence; then execute S310;

S309, arranging the new network search order from high to low according to the successful times of network search in each network mode; then execute S310;

Specifically, when there are multiple successful network search network modes in the historical network search mode, the historical network search success times of each network mode are arranged from high to low, that is, the network mode with the most historical network search success times will be prioritized. Search the network, there is a chance to further improve the success rate of the search network.

S310, perform a network search;

S311, determine whether the search network is successful? If the network search is successful, then execute S316; if the search network is unsuccessful, then execute S312;

S312, calculate the probability of failure of historical network search under the current network mode according to the historical multi-mode network search list;

Specifically, the probability of failure to search the network in the current network mode, that is, if the historical location A is in the current network mode, search the network 10 times and succeed 2 times, then the probability of network search failure is 80%, and the chance of failure is high. It is necessary to extend the default network search time interval to avoid wasting power caused by intensive network search.

S313, determine whether the probability is greater than a preset threshold? If yes, execute S314; otherwise, execute S315;

S314, run a specific algorithm to calculate the next time to search the network and execute it;

Specifically, the specific algorithm is: set the historical failure probability to be P, the current number of retries to be n, the time interval for the next trigger to re-search the network to be T, and the default network search interval to be T0, there are:

S315, executing the default network search interval;

S316, save the current geographic location and its search results in the historical geographic location information database.

The intelligent search method implemented above enables the mobile terminal to select the search mode according to the historical search results when the network is disconnected, and further determine the time to search the network again according to the search results and the probability of successful historical search, which not only improves the It can improve the probability of successful network search once or improve the efficiency of network search. In places with poor network coverage, the time to search the network again can be adjusted reasonably to reduce unnecessary power consumption caused by continuous network search.

Embodiment 4

A fourth embodiment of the present invention provides an intelligent network search device, as shown in FIG. 6 , including a location acquisition unit 10 , a network search list acquisition unit 20 , and a network search unit 30 .

The location obtaining unit 10 is configured to obtain the current geographic location when receiving the terminal mobile communication network disconnection signal;

Among them, the mobile communication network includes but is not limited to the commonly used CDMA, WCDMA, GSM, LTE, etc. The disconnection of the mobile communication network means that the mobile terminal cannot communicate with the mobile network base station, which makes the mobile terminal unable to communicate normally and use mobile data. state of waiting. Geographical location GL (Geographical location) refers to the geographic location information where the search occurs. It consists of three vectors: longitude X, latitude Y and altitude Z. The present invention includes the current address position and the historical geographic position, which are acquired by the mobile terminal through GPS satellite positioning.

The search network list acquisition unit 20 is used to compare the current geographic location and the historical geographic location information database. If there is a Euclidean space distance difference with the current geographic location in the historical geographic location information database, the historical geographic location is less than the set threshold. , then output the historical multi-mode search network list corresponding to the historical geographic location;

The historical geographic location information database GLDB (Geographical Location Data Base) is a network search information database based on geographic location information, including the location of the mobile terminal and the corresponding A collection of information about the search time, the search network mode, and the success of the search. The historical geographic location information database GLDB is stored in the memory 160 described in FIG. 1 .

For example, define the relevant data table structure in the historical geographic location information database as follows:

The NetType table defines the codes of each network mode, as follows:

The following table records the historical data of searching the network at various locations. GL indicates the geographical location of the search, State indicates whether the search is successful, 1 indicates success, 0 indicates failure, NetType indicates the network type of the search, and TimeStamp is the time when the search occurred.

Euclidean space distance, also known as Euclidean metric, is a commonly used definition of distance, which refers to the true distance between two points in m-dimensional space, or the natural length of the vector (that is, the point to distance from the origin). Euclidean distance in 2D and 3D space is the actual distance between two points.

When the mobile terminal is disconnected from the network, the coordinates of the current address location are collected, and the current geographic location is compared with the historical geographic location information database. If the historical address location that is close to the current geographical location has also been disconnected from the Internet, the network mode that has been successfully searched in the past is used as the current search target. Compared with the default search order, it is an optimized search order. Therefore, Output the historical multimodal search network list corresponding to the historical geographic location.

The web search unit 30 is configured to search the web according to the historical multi-mode web search list, and if the web search is successful, save the current geographical location and the web search result in the historical geographical location information database.

The intelligent network search device implemented above no longer searches the network through the default network mode sequence, but searches the network with reference to the historical network search success probability close to the current location from large to small, which means that the search is eliminated. Some networks have a high probability of failure at the current location, thereby increasing the chance of a successful network search, avoiding wasting time and wasting electricity.

Calculate the interval for the next network search, and refer to the probability of historical network search failures in the current network mode. If the probability of historical network search failures is high, it means that the network in the area is very weak. If no adjustment is made, the default network search time interval will be used to search the network. , it will bring huge power consumption. Properly adjusting and extending the network search interval can reduce the power consumption of the network search.
