All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic diagram of a multi-mode terminal according to a first embodiment of the present application.

The multimode terminal 100 includes a public network control module 10, a private network control module 20, and a GNSS module 30.

The public network control module 10 is used for realizing public network communication. The public network is, for example, a common circuit switching network, and can be suitable for communication requirements of the general public, such as backbone and branch networks erected by existing network communications, telecommunications, iron communications, and the like. The private network control module 20 is used for realizing private network communication. The private network is, for example, a private network, such as a railway system private network, a flood prevention private network, a military private network, or the like, and a private network may be set up in a certain system to serve only the system. The private network may also provide an interface to a public network to communicate with the public network, such as to call a user of the public network. The GNSS module 30 is used to acquire GNSS data. The public network control module 10 and the private network control module 20 share GNSS data of the same GNSS module 30.

The public network control module 10 and the private network control module 20 share GNSS data of the same GNSS module 30, so that the GNSS module in the multimode terminal 100 can meet the requirements of positioning the public network control module 10 and the private network control module 20, and the like, thereby reducing the size of the multimode terminal and lowering the production cost.

The public network control module 10 may be communicatively coupled to a private network control module 20. Specifically, the public network control module 10 and the private network control module 20 are connected through a data bus and a control bus.

Alternatively, the data bus and the control bus may both adopt a UART (universal asynchronous Receiver/Transmitter) mode.

Alternatively, both the data bus and the control bus may adopt an SPI (Serial peripheral interface) mode.

As shown in fig. 1, the public network control module 10 is communicatively connected to the GNSS module 30. The public network control module 10 and the GNSS module 30 may be connected by a data bus and a control bus.

The data bus may employ a UART scheme. The data bus may also be in SPI mode. The data bus may also be an IQ bus. Of course, the data bus may adopt two ways at the same time, such as adopting UART and SPI at the same time, or adopting UART and IQ buses at the same time.

Alternatively, the control bus may employ a UART scheme. The control bus can also adopt an MIPI mode, wherein the MIPI is short for Mobile Industry Processor Interface, namely a Mobile Industry Processor Interface.

The public network control module 10 receives the GNSS data request sent by the private network control module 20, responds to the GNSS data request sent by the private network control module 20, obtains GNSS data from the GNSS module 30, and forwards the GNSS data to the private network control module 20. Specifically, after receiving the GNSS data request sent by the private network control module 20, the public network control module 10 sends the GNSS data request to the GNSS module 30, the GNSS module 30 receives the GNSS data request and replies corresponding GNSS data to the public network control module 10, and the public network control module 10 forwards the GNSS data acquired by the GNSS module 30 to the private network control module 20.

In some embodiments, the GNSS data received by the public network control module 10 is directly forwarded to the private network control module 20 for use, so that the public network control module 10 and the private network control module 20 can share the same GNSS module 30.

In other embodiments, the GNSS data received by the public network control module 10 may be used by the public network control module 10 on one hand, and may be forwarded to the private network control module 20 on the other hand, so as to be used by the private network control module 20, so that the GNSS module 30 in the multimode terminal 100 may meet the requirements of positioning the public network control module 10 and the private network control module 20, and the like, and may reduce the size of the multimode terminal and reduce the production cost.

Of course, the public network control module 10 may also send its own GNSS data request to the GNSS module 30, so that the GNSS module 30 replies with the corresponding GNSS data. For this situation, the public network control module 10 may only provide the GNSS data for the public network control module 10 itself, may also directly forward the GNSS data to the private network control module 20 for use by the private network, but not for use by the public network control module 10, and may further forward the GNSS data to the private network control module 20 while providing the GNSS data for use by the public network control module 10, so as to implement that the public network control module 10 and the private network control module 20 jointly use the GNSS data.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a public network control module in a first embodiment of a multimode terminal according to the present application. The public network control module 10 may be a communication control module of a mobile terminal class. Specifically, the public network control module 10 may include a public network chip 11, and the public network chip 11 is in communication connection with the private network control module 20.

The public network control module 10 may further include a wireless communication module 12 coupled with the public network chip 11, a memory 13, a public network SIM card 14, and a flash memory module 15. The wireless communication module 12 is used for realizing wireless connection between the public network control module 10 and external devices.

The GNSS module 30 is configured to receive a GNSS data request sent by the public network control module 10, and transmit the acquired GNSS data to the public network control module 10.

As shown in fig. 1, the GNSS module 30 in the present embodiment may include a GNSS chip 31 and an antenna 32. The GNSS chip 31 may be disposed on the public network chip 11, and may directly provide GNSS data to the public network control module 10. The GNSS chip 31 may support a main Positioning control module such as a GPS (the GPS is a short for an english Global Positioning System, and chinese is a Global Positioning control module), a beidou, a galileo, and a GLONSASS (GLONASS, an abbreviation of russian "Global NAVIGATION SATELLITE System), that is, a GLONASS. The antenna 32 may be an active antenna or a passive antenna.

In this embodiment, the private network control module 20 may send a GNSS data request to the public network control module 10, the public network control module 10 may forward the GNSS data request to the GNSS module 30 to obtain GNSS data, and the public network control module 10 forwards the obtained GNSS data to the private network control module 20. After the private network control module 20 receives the GNSS data, the private network realizes a positioning function using the GNSS data. In this way, the public network control module 10 and the private network control module 20 can share the same GNSS module 30.

As shown in fig. 1, the multimode terminal 100 may further include an AGNSS module 40. The AGNSS module 40 is a module for implementing acquiring AGNSS data. The AGNSS technology generally refers to technologies for assisting GNSS positioning, including a-GNSS, WIFI, bluetooth, UWB (Ultra Wideband, which is a carrier-free communication technology), sensors, and the like. Wherein, the A-GNSS is an Assisted-Global Navigation Satellite System, and has the function of assisting the positioning of Global Navigation satellites. The AGNSS module 40 in this embodiment may obtain AGNSS data in a wireless manner, such as a base station, WIFI, or a wireless network.

The AGNSS module 40 may be communicatively coupled to the public network control module 10.

The private network control module 20 may send a GNSS data request or AGNSS data request to the public network control module 10.

The public network control module 10 may further respond to the GNSS data request sent by the private network control module 20 or the AGNSS data request sent by the private network control module 20, obtain AGNSS data from the AGNSS module 40, and forward the AGNSS data to the private network control module 20. After receiving the AGNSS data, the private network control module 20 may perform positioning using the AGNSS data.

Of course, the public network control module 10 may request the GNSS data from the GNSS module 30 or request the AGNSS data from the AGNSS module 40 in response to the GNSS data request, so that the GNSS data of the GNSS module 30 or the AGNSS data of the AGNSS module 40 may be obtained based on the same data request, and when the GNSS module 30 fails and cannot be used, the AGNSS data may be obtained from the AGNSS module 40 to achieve positioning.

The public network control module 10 may also send data requests to the GNSS module 30 and the AGNSS module 40 respectively, specifically, send GNSS data to the GNSS module 30 and request AGNSS data to the AGNSS module 40, in response to the GNSS data request. When the data requests are sent to the GNSS module 30 and the AGNSS module 40 respectively, the AGNSS data in the GNSS data and the AGNSS data can be obtained for use or forwarded, so that the data obtaining efficiency can be improved, and the positioning is faster and more accurate.

Of course, the public network control module 10 may also send its own GNSS data request or AGNSS data request to the AGNSS module 40, so that the AGNSS module 40 replies AGNSS data in response to the GNSS data request or AGNSS data request.

The AGNSS data received by the public network control module 10 may be used by the public network, on the one hand, and may be forwarded to the private network control module 20, on the other hand, for use by the private network, so that the AGNSS module 40 in the multimode terminal 100 may meet the requirements of auxiliary positioning of the public network control module 10 and the private network control module 20, and the like, which may reduce the size of the multimode terminal and reduce the production cost.

The AGNSS module 40 and the public network control module 10 may be connected through a control bus and a data bus. Alternatively, the data bus and the control bus may employ UARTs. The data bus and control bus may also employ SPI.

The AGNSS module 40 may be used as a backup when the GNSS module 30 fails and cannot be used, so as to meet the positioning requirements of the public network control module 10 and the private network control module 20. Certainly, the GNSS module 30 and the AGNSS module 40 may be used simultaneously, and the main module and the auxiliary module cooperate with each other to achieve fast positioning and improve positioning accuracy. That is, the public network control module 10 and/or the private network control module 20 may perform positioning by using the combined action of GNSS data and AGNSS data, where the GNSS data is used as main positioning data and the AGNSS is used as auxiliary positioning data, so as to improve the positioning time and accuracy of the public network.

Alternatively, the GNSS module 30 and the AGNSS module 40 may be built into the public network control module 10. The GNSS module 30 and the AGNSS module 40 may be provided separately from the public network control module 10.

The private network control module 20 may include a private network chip (not shown) that is communicatively connected to the public network chip 11.

As shown in fig. 1, the multimode terminal 100 may further include a public network rf module 50, and the public network rf module 50 is communicatively connected to the public network control module 10. The public network radio frequency module 50 and the public network control module 10 can be connected through a control bus. Specifically, the public network rf module 50 is communicatively connected to the public network chip 11 in the public network control module 10. The public network radio frequency module 50 and the public network chip 11 can be connected through control bus communication. Alternatively, the control bus may employ a UART.

In this embodiment, the public network control module 10 adjusts the power of the public network rf module 50 according to its own status. The self-state of the public network control module 10 specifically refers to the working state of other functional modules inside the public network control module 10 except for the modules related to the positioning function. The working state includes, for example, an idle state or a non-idle state, and the public network control module 10 controls the working mode of the public network radio frequency module 50 according to its own state to adjust power consumption. The operating mode includes, for example, a low power operating state. The low power operation state may be an operation state corresponding to the lowest rf power at which the public network rf module 50 transmits rf signals from the antenna. The public network control module 10 controls the public network radio frequency module 50 to switch to the low power operation state when being in the idle state. The fact that the public network control module 10 is in the idle state by itself means that other functional modules inside the public network control module 10 except for the modules related to the positioning function are in the idle state.

Optionally, the operating mode includes, for example, a low power operating state, a normal power operating state, or a high power operating state. The public network rf module 50 divides the rf power transmitted from the antenna 32 into three levels, low power, normal power and high power.

Of course, the self-state of the public network control module 10 may include states with different busy levels, for example, the busy level may be defined according to the working state of the function module in the public network control module 10, and the busy level may be set in a specific case. The public network control module 10 adjusts the power of the public network radio frequency module 50 according to different grades.
