Description

Positioning method of mobile terminal and mobile terminal

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method for locating a mobile terminal and a mobile terminal.

Background technique

The Global Navigation Satellite System (GNSS) refers to all satellite navigation systems, including global, regional, and enhanced satellite systems, such as the Global Positioning System (GPS) in the United States, and Russia. Glonass, Galileo in Europe, China's Beidou satellite navigation system (Beidou or Compass in English); and related augmentation systems, such as the US Wide Area Augmentation System (WAAS), Europe's European static navigation overlap The system (European Geostationary Navigation Overlay system, EGNOS) and Japan's Multi-Functional Satellite Augmentation System (MSAS) also cover other satellite navigation systems under construction and later. Satellite receivers may support the reception of navigation signals from a variety of satellite navigation systems to meet the positioning requirements under different conditions, or to achieve optimal positioning performance. Such receivers are referred to as multimode satellite receivers. Different degrees of coordination between various satellite navigation systems can also be implemented to improve the fusion positioning performance of multi-mode satellite receivers.

The traditional independent GNSS receiver needs to decode the navigation message and ephemeris of multiple satellites before the first positioning can be performed, so the first positioning time is long. Therefore, the industry has proposed Assisted GNSS technology to improve the first positioning speed. The most typical is the auxiliary. Assisted Global Positioning System (AGPS) technology.

AGPS has become a mainstream commercial positioning technology due to its advantages of fast first positioning and high positioning accuracy. The technology provides auxiliary data such as almanac, ephemeris, clock and reference position for the GPS receiver of the mobile terminal through the AGPS server, which effectively improves the positioning speed and sensitivity of the GPS receiver of the mobile terminal, and the key point of the realization is: estimating the mobile terminal The rough position, according to the rough position, almanac, clock and other information to provide GPS satellite Doppler frequency offset, code delay, square key, elevation, ephemeris and other auxiliary information, thereby narrowing the frequency, code delay search space, avoiding stars Calendar decoding requirements for fast positioning. Where the estimate of the coarse location is typically the location of the cell site where the mobile terminal is located or The location of the WiFi hotspot cell is determined by looking up the geographic location corresponding to the base station in the base station database. The base station database specifically refers to a base station identifier (IDentity, ID) such as a Cell-ID, a Service Set Identifier (SSID) or a Media Access Control (MAC) address of a WiFi AP, and a base station or an access point ( Access Point, AP) A database of hotspots corresponding to physical locations.

In the prior art, the positioning mode of the mobile terminal is usually directly set to AGPS positioning. The AGPS positioning requires the terminal to connect to the AGPS server almost every hour to download the latest auxiliary data for positioning, and the AGPS positioning performance is excellent. In actual AGPS positioning, the mobile terminal cannot use AGPS positioning for various reasons, such as: AGPS server failure, unable to provide service; or AGPS server does not have accurate base station location database; or mobile network congestion or gateway routing configuration is not accurate, As a result, the mobile terminal cannot connect to the AGPS server. In the prior art, the timeout period for the mobile terminal to access the AGPS server is usually set to be long, for example, 30 seconds. If the server is faulty, it cannot be known in time, which results in long positioning time and poor user experience. Therefore, it is necessary to propose a method to solve the above problem.

detailed description

The technical solutions in the embodiments of the present invention will be described with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The invention provides a positioning method and a mobile terminal of a mobile terminal, which can shorten the positioning time and improve the user experience. The mobile terminal provided by the present invention may be a terminal device such as a mobile phone or a tablet computer. The mobile terminal in the present invention is simultaneously connected to the first radio access network and the second radio access network, the mobile terminal acquires circuit-switched voice service through the first radio access network, and the mobile terminal acquires packet switching through the second radio access network. The data service, the positioning service mentioned in the embodiment of the present invention belongs to a packet switched data service.

Referring to FIG. 1, an embodiment of a positioning method of a mobile terminal of the present invention includes:

101. Determine a network scenario where the mobile terminal is located;

In this embodiment, the network scenario includes a type of the second radio access network to which the mobile terminal is connected, and the mobile terminal connects to the connection state of the location server through the second radio access network, and the first radio access network to which the mobile terminal is connected At least one of a status of a system identification code and a status of a home network of a mobile terminal's telephone number, the positioning server including an Assisted Global Navigation Satellite System (AGNSS) positioning server or an assisted global positioning system (Assisted Global) Positioning System, AGPS) locates the server.

102. Select a positioning manner of the mobile terminal according to a network scenario in which the mobile terminal is located.

In this embodiment, when positioning is required, the default positioning mode is not used for positioning, but the mobile terminal is selected according to the network scenario in which the mobile terminal is located, so that the mobile terminal is not in use. In any scenario, a more suitable positioning method can be used to achieve fast positioning.

Referring to FIG. 2, a specific embodiment of the positioning method of the mobile terminal of the present invention includes:

201, determining whether the type of the second radio access network connected to the mobile terminal is a preset type of the wireless packet switching network; if yes, executing step 202, performing step 203;

In a specific implementation, the preset type of the wireless packet switching network may include: a 4th generation mobile communication technology (4G) network, a Long Term Evolution (LTE) network, and an evolved high-speed packet data ( Evolved High Rate Packet Data, eHRPD) network. The preset type of wireless packet switched network usually has the characteristics of fast transmission data rate or the possibility of being unable to connect to the positioning server with a certain probability.

202. The second wireless access network accesses the positioning server for positioning, and sets a timeout period of the mobile terminal accessing the positioning server by using the second wireless access network to a second time.

203. The timeout period for the mobile terminal to access the positioning server by using the second wireless access network is the first time.

In a specific implementation, the second time is less than the first time, and the first time may be a default timeout period for accessing the positioning server through the first wireless access network, which is usually longer. For example, when the first time is 30 seconds, the second time can be set to 10 seconds, and of course the second time can also be set to other times less than the first time.

When the type of the second radio access network is a preset type of the wireless packet switching network, since the second radio access network has a fast transmission data rate, the second access network is selected to access the positioning server. Positioning. In this case, if the mobile terminal can be correctly connected to the positioning server, the mobile terminal can quickly achieve positioning, and since the second wireless access network at this time has a certain probability of being unable to connect to the positioning server, the positioning server will also be accessed. The timeout period is set smaller. If the mobile terminal cannot access the positioning server through the second wireless access network to complete the positioning (for example, unable to connect to the positioning server, or the positioning server does not have an accurate base station location database), then the comparison is made due to the timeout setting. Small, after the timeout, the mobile terminal can quickly fall back to other positioning modes (such as ephemeris extended positioning mode) for positioning, thereby achieving fast positioning.

In this embodiment, when the type of the second radio access network to which the mobile terminal is connected is a preset type of the wireless packet switching network, the second radio access network is selected to access the positioning server to complete the positioning, and the positioning time is set. Smaller, otherwise the timeout period for the mobile terminal to access the location server is the default longer timeout, so that regardless of the type of the second wireless access network to which the mobile terminal is connected, You can choose the appropriate positioning method to achieve fast positioning.

Referring to FIG. 3, another specific embodiment of the positioning manner of the mobile terminal of the present invention includes:

301. When the type of the second radio access network connected to the mobile terminal is a preset type of the wireless packet switching network, determine whether the mobile terminal can connect to the positioning server by using the second radio access network; if yes, perform step 302. Otherwise, step 304 is performed;

In a specific implementation, when the type of the second radio access network connected to the mobile terminal is a preset type of the wireless packet switching network, the connection server may be attempted to connect to the positioning server in the background for a preset number of times. If the server is set, the connection status of the positioning server is abnormal. Otherwise, the connection status of the positioning server is set to be normal.

The preset wireless packet switching network type may include: a 4G network, an LTE network, or an eHRPD network. A preset type of wireless packet switched network typically has the characteristics of fast transmission data rate or a probability of being unable to connect to a location server.

302. Set the connection status of the positioning server to be abnormal.

The abnormal connection status of the positioning server may be a server exception, or the second wireless access network is abnormal (such as network congestion, or the routing policy configuration of the gateway is inaccurate), and cannot be connected to the positioning server.

303. Select an ephemeris extended positioning manner to perform positioning, or select to establish a temporary data service through the first wireless access network to access the positioning server for positioning;

In a specific implementation, when the connection status of the positioning server is abnormal, the ephemeris extended positioning mode may be selected for positioning, or the temporary data service may be established through the first wireless access network to access the positioning server for positioning. At this time, the mobile terminal can maintain a connection state with the second wireless access network. After the positioning is completed, the temporary data service of the first radio access network will be closed.

The ephemeris extension positioning method refers to the Ephemeris Extension (EE) server providing the mobile terminal with information such as ephemeris and clock valid for a long time (for example, seven days) through the communication network, and assisting the mobile terminal to quickly locate. Since the ephemeris extended positioning does not require the mobile terminal to connect to the EE server in real time to obtain the positioning assistance data, the positioning can be achieved. Therefore, when the positioning server cannot be accessed through the second wireless access network for positioning, the ephemeris extended positioning can be used for fast positioning. . The specific manner of selecting the ephemeris extended positioning may be: setting the timeout time for accessing the positioning server through the second wireless access network to 0, or directly skipping the AGNSS positioning or the AFPS positioning, and directly using the ephemeris extended positioning, where No specific restrictions.

The first radio access network, such as a 1x network, is generally used to acquire circuit-switched voice services, such as a call, etc., when the location server cannot be accessed through the second radio access network, the temporary data service can be established through the first radio access network. Access the location server for fast positioning.

304. Set the connection status of the positioning server to be normal;

305. Access the positioning server through the second wireless access network for positioning.

If the location of the location server is normal, accessing the location server through the second wireless access network enables fast and accurate positioning.

In addition, when the mobile terminal initially connects to the second radio access network, the second radio access network allocates an Internet Protocol (IP) address to the mobile terminal. When the mobile terminal moves, the second wireless access network may assign a new IP address to the mobile terminal, and the mobile terminal acquires a new IP address allocated by the second wireless access network, and then determines that the mobile terminal passes the second wireless connection again. Whether the incoming network can connect to the positioning server. If the mobile terminal cannot connect to the positioning server through the second wireless access network, set the connection status of the positioning server to be abnormal. Otherwise, set the connection status of the positioning server to be normal. For subsequent processing, refer to The corresponding description above.

In this embodiment, when the connection state of the mobile terminal is connected to the positioning server through the second wireless access network is normal, the second wireless access network accesses the positioning server for positioning, otherwise, the ephemeris extended positioning mode is selected for positioning, or Selecting to establish a temporary data service by using the first radio access network to access the positioning server for positioning, so that the positioning mode of the positioning server is normal or abnormal, and the positioning method can be used to implement fast positioning.

Referring to FIG. 4, another specific embodiment of the positioning manner of the mobile terminal of the present invention includes:

401. When the type of the second radio access network that is connected to the mobile terminal is a preset type of the wireless packet switching network, acquire a system identifier of the first radio access network that is connected to the mobile terminal.

402, determining whether the system identifier of the first radio access network is in the first blacklist, and if so, executing step 403, otherwise, performing step 404;

In the specific implementation, the first blacklist may be created according to user complaints, network side feedback or pre-tested experiments. The first blacklist includes the system identification code of the wireless access network with poor network status.

When the type of the second radio access network connected by the mobile terminal is a preset type of the wireless packet switching network, the system identifier of the first radio access network may be obtained by using a system broadcast message of the first radio access network, or The location allocation message of the high speed packet data, the 3G1X parameter or the sector identification information acquires the system identification code of the first radio access network. The system identification code of the first radio access network is In the blacklist, the network status of the second radio access network is not good, and the second radio access network cannot quickly and correctly connect to the positioning server.

Since the second radio access network itself may not have a system identification code, and when the second radio access network has a system identification code, the system identification code of the second radio access network is the same as the system identification code of the first radio access network. Therefore, in this embodiment, the state of the second radio access network is identified by determining whether the system identification code of the first radio access network is in the first blacklist.

403. Select an ephemeris extended positioning manner to perform positioning, or select to establish a temporary data service by using the first wireless access network to access a positioning server for positioning;

404. Access the positioning server through the second wireless access network for positioning.

In this embodiment, when the system identification code of the first radio access network is in the blacklist, the ephemeris extended positioning mode is selected for positioning, or the temporary data service is established through the first radio access network to access the positioning server for positioning. Otherwise, the positioning server is accessed through the second wireless access network for positioning. Regardless of whether the system identification code of the first radio access network to which the mobile terminal is connected is in the blacklist, the positioning method can be used to achieve fast positioning.

Referring to FIG. 5, another specific embodiment of the positioning manner of the mobile terminal of the present invention includes:

501. Obtain a phone number of the mobile terminal when the type of the second radio access network connected by the mobile terminal is a preset type of the wireless packet switching network.

502, determining whether the home network of the mobile terminal's phone number is in the second blacklist; if yes, executing step 503, otherwise, performing step 504;

The home network in the second blacklist is usually a network with poor connection status.

The attribution network identification of the mobile terminal's telephone number is achieved through pre-made city/area number segment table queries. The mobile subscriber's telephone number (Mobile Subscriber International ISDN/PSTN number, MSISDN) has the format: CC+NDC+SN. Among them, CC = country code (China is 86), NDC = domestic destination code, SN = user number. The China Domestic Destination Code (NDC) includes the access number N1N2N3 and the identification number H1H2H3H4 of the Home Location Register (HLR). The access number is used to identify different operators' networks or different operators' different service networks, such as 139, 138, and 133. The HLR identification number indicates the HLR of the user's home city/region. In this way, a mobile phone number segment table of each city/region network can be pre-made based on the NDC, and when needed, the home network of the mobile terminal's telephone number can be identified by looking up the table.

503. Select an ephemeris extended positioning manner to perform positioning, or select to pass the first radio access network. Establish a temporary data service to access the positioning server for positioning;

504. Access the positioning server through the second wireless access network for positioning.

It should be noted that, in the case of roaming, the home network will be a network different from the first radio access network and the second radio access network, but the second radio access network accesses the positioning server for positioning. The home network needs to be relied on, so when the home network is not good, the positioning time for accessing the positioning server through the second wireless access network is directly affected. In the case of non-roaming, the home network and the second wireless access network refer to the same network.

In this embodiment, when the home network of the phone number of the mobile terminal is in the second blacklist, the ephemeris extended positioning mode is selected for positioning, or the temporary data service is established through the first wireless access network to access the positioning.

Otherwise, the setting unit 7013 sets the connection status of the positioning server to be normal.

Generally, when the mobile terminal initially connects to the second radio access network, the second radio access network allocates an Internet Protocol (IP) address to the mobile terminal. When the mobile terminal moves, the second radio access network may assign a new IP address to the mobile terminal, the first obtaining unit 7014 acquires a new IP address allocated by the second radio access network, and the second determining subunit 7012 again.
