[0036] The above is a brief introduction to the terms involved in the embodiments of the present application.

[0037] With the rapid development of the fifth generation mobile communication technology (5G), more and more new miniaturized base stations are being built, and the number of infrastructure equipment involved is also increasing. Users are gradually getting used to the ubiquitous coverage of mobile communication signals in their daily lives. At the same time, users often use CPE when they go out, especially when traveling abroad.

[0038] In the related technology, the base station in mobile communication is generally fixedly installed at a pre-selected site to provide wireless communication equipment around. Although wireless CPE can convert mobile signals into wireless WIFI signals, users will not be able to use the communication network when traveling abroad or in remote areas of China or when the mobile operator's network fails, resulting in poor mobile communication signals. In other words, users can only use data services through wireless and cannot make phone calls.

The mobile power module is electrically connected to the processor and is used to provide power to the small base station module and the wireless backhaul module. The small base station module and the wireless backhaul module are communicatively connected. In the case of poor communication signals, the wireless backhaul module can establish a backhaul link, and then the small base station module can perform wireless signal connection through the backhaul link, thereby ensuring the communication quality of the terminal device.

[0040] In addition, since the processor in the embodiment of the present application adopts a system-level Soc chip, users can carry a small base station with them to provide voice and data services for mobile communication devices in the surrounding coverage area.

The electronic device 100 may be a portable small base station. The small base station may include a mobile power module 101 and at least one processor 102.

[0044] The processor 102 in the embodiment of the present application adopts a system Soc chip. The chip technology is an integrated design, with a volume of less than 1L and a weight of less than 1kg, which is light and easy to carry.

[0045] The communication line may include a channel for transmitting information between the above components.

[0046] In some embodiments, the wireless backhaul module is used to connect to the local WIFI network and establish a backhaul link to the operator's core network. In other words, when the communication signal of the terminal device is poor, the wireless backhaul module can connect to the local wireless WIFI network and establish a backhaul link to the operator's core network.

The backhaul control unit can be used to establish an operator-specific backhaul link, transparently transmit the received small base station module data to the operator's security gateway via the Internet, and then enter the operator's core network for data interaction.

[0049] In some embodiments, the small base station module can be used to establish a wireless signal connection based on the backhaul link of the wireless backhaul module to provide 4 / 5G mobile communication signal coverage.

[0050] Optionally, the small base station module includes: a second antenna unit, a radio frequency processing unit, and a baseband processing unit, wherein the radio frequency processing unit is connected to the baseband processing unit via a communication interface, and the radio frequency processing unit is connected to the second antenna unit via a communication line.

[0054] In the embodiment of the present application, the small base station module and the wireless backhaul module are connected via a data interface.

[0055] In one scenario, after the wireless WIFI unit establishes a backhaul link, the terminal device can conduct voice and data services normally with the small base station module, and the generated service data is sent to the core network via the backhaul link.

[0056] In the embodiment of the present application, the mobile power module is also configured with a USB power supply interface, which can provide power for terminal devices or digital devices.

[0057] The small base station may also include a memory, which may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to include or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to this.

[0058] In one possible design, the memory can exist independently of the processor 102, that is, the memory can be a memory outside the processor 102. In this case, the memory can be connected to the processor 102 through a communication line to store execution instructions or application code, and the processor 102 controls the execution to implement the network quality determination method provided in the following embodiment of the present application. In another possible design, the memory can also be integrated with the processor 102, that is, the memory can be the internal memory of the processor 102, for example, the memory is a high-speed cache, which can be used to temporarily store some data and instruction information, etc.

[0059] As an implementation manner, the processor 102 may include one or more CPUs.

[0060] The above describes the structure of the portable small base station provided in the embodiment of the present application.

A person of ordinary skill in the art can know that with the evolution of electronic devices and the emergence of other electronic devices, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0062] The communication methods in the following embodiments can all be implemented in the electronic device 100 having the above hardware structure. Figure 2 As shown, the communication method of an embodiment of the present application is described.

[0063] S201, establish a WIFI connection.

[0064] In some embodiments, the electronic device can establish a connection with a wireless WIFI network where the terminal device is located through the first antenna unit in the wireless backhaul module.

[0069] S204: Process the baseband signal.

[0079] In the embodiment of the present application, since the Internet connection is used instead of a dedicated transmission network, the route from the terminal network to the core network is too long, which can easily lead to a large delay problem. Furthermore, the electronic device can arrange the front-end transfer nodes by region, and select the corresponding front-end node according to the device routing information and the minimum delay.

[0080] S303: Determine the encryption method according to the confidence level.

[0081] In the embodiment of the present application, different operators have different corresponding confidence levels, and thus adopt different encryption methods. The electronic device can select different encryption methods according to the network confidence levels of different operators.

[0082] Exemplarily, different confidence levels are set for the network type in which the terminal device is located. Exemplarily, the network confidence of operator A is set to level one, the network confidence of operator B is set to level two, and the network confidence of operator C is set to level two. For example, for operator A with a network confidence of level one, select an encryption method with lower strength and lower latency to prioritize network performance. For operator B with a network confidence of level three, select a moderate encryption method to balance network performance and data security. For operator C with a network confidence of level three, select an encryption method with higher strength and higher latency to prioritize data security.

[0083] S304: Establish a VPN pipeline.

[0085] S305: Establish a backhaul link.

[0086] In an embodiment of the present application, the electronic device establishes a wireless data backhaul link between the terminal network and the front-end node based on the VPN pipeline.

[0087] It should be noted that the communication method involved in S201 to S206 and the backhaul link establishment method involved in S301-S305 are described in detail above.
