Description

Technical Field

[0001] The present invention belongs to the technical field of wireless network communications, and in particular relates to a multimedia device with a mobile communication base station. Background Art

[0002] With the rapid development of the Internet of Things (IoT) technology, smart homes have become an integral part of modern family life. Currently, smart home systems face multiple challenges, including limited network performance, insufficient capacity and compatibility, a lack of emergency applications, and privacy and security risks. Current smart home systems primarily rely on wireless communication technologies such as Wi-Fi and Bluetooth to interconnect devices. However, traditional wireless networks have numerous limitations, such as limited coverage, frequent signal interference, and insufficient stability with high concurrent connections. With the rapid increase in the number of smart devices in homes, existing network architectures struggle to support the large number of devices online simultaneously, resulting in increased device response times and a negative impact on user experience. In emergencies such as fires and earthquakes, traditional networks are prone to disruption due to infrastructure damage, making it impossible to effectively utilize smart home devices (such as cameras and voice systems) to assist rescue efforts, thereby reducing search and rescue efficiency.

[0003] The introduction of 5G technology offers a breakthrough for these challenges. Its high speed (theoretical peak of 20Gbps), ultra-low latency (1ms), and high-capacity connectivity (millions of devices per square kilometer) significantly enhance the real-time responsiveness and device collaboration efficiency of smart homes. Furthermore, the wide-area coverage and edge computing capabilities of 5G base stations support seamless connectivity and localized data processing within and outside the home, reducing reliance on the cloud and enhancing system reliability.

[0004] In the existing published patent application documents, Chinese utility model patent application number CN201910725417.7 discloses a surveillance camera device with a femtocell base station, including a housing and a camera. The camera is arranged in the housing, and the housing is installed under the ceiling. A mounting plate is provided in the housing to divide the inner cavity of the housing into a camera compartment and a base station compartment, and the base station compartment is located above the camera compartment. The camera is fixed on the mounting plate. The device also includes a base station and a hub, and the base station is arranged in the base station compartment.

[0005] For another example, Chinese invention patent application number CN202111221666.6 discloses an invention named a base station switching method, apparatus, multimedia device and storage medium. The method includes: querying the route of the bus. If the bus stops at the current station, detecting the first multimedia data that has been cached and not played in the multimedia device, predicting the total time taken for the bus to depart from the current station and travel to the next station, and the total time taken to stop at the next station. If the total duration of the first multimedia data covers the total time, maintaining access to the current base station; if the total duration of the first multimedia data does not cover the total time, switching from access to the current base station to access to other base stations while the bus stops at the current station; if access to other base stations is successful, downloading the second multimedia data and caching it to the multimedia device, so as to play the second multimedia data after the first multimedia data is played. Switching base stations in a stable network environment can ensure the efficiency of switching base stations.

[0006] For another example, Chinese invention patent application number CN 202111098445.4 proposes a method for enhancing multimedia call control in the next generation mobile communication system. During the attach process or the registration area update process, the serving base station sends an instruction to the user equipment indicating whether Internet Protocol Multimedia Subsystem Voice over Packet Switched Sessions is supported. Upon receiving the instruction to support Internet Protocol Multimedia Subsystem Voice over Packet Switched Sessions, the user equipment triggers the registration Internet Protocol Multimedia Subsystem process. However, when a mobile station originates / mobile station terminates a call, the network determines that the user equipment may be in a state where voice services are not supported because the network cannot successfully provide Internet Protocol Multimedia Subsystem Voice over Packet Switched Sessions on the current serving cell connected to the 5G core network. The network then triggers a radio access technology change or an evolved packet system fallback process, so that the user equipment switches to a target cell that supports Internet Protocol Multimedia Subsystem Voice over Packet Switched Sessions.

[0007] The above-mentioned utility model or invention patent applications all have insufficient deep coordination mechanisms between base stations and devices. The base stations only serve as data transmission channels and fail to fully utilize their network slicing, dynamic resource allocation and other functions, resulting in limited customized service capabilities for smart home scenarios.

The display screen 2 is electrically connected to the PLC module of the multimedia motherboard through a flexible cable, and the display screen 2 is fixed to the front housing 1 by a cantilever buckle; In a specific embodiment, the multimedia driver board 3 is fixed to the inner side of the front shell 1 by bolts. The multimedia driver board 3 is a printed circuit board. The multimedia driver board 3 is provided with an audio output module, a USB module, a storage module, a video signal module, a touch signal module, a second WIFI module, an advertising module, a 5GNR broadcast module, a first PLC module, and an environmental adaptation module, wherein: the audio output module, the USB module, the storage module, the video signal module, the touch signal module, the second WIFI module, the advertising module, and the 5GNR broadcast module are all electrically connected to the first PLC module; the first PLC module is responsible for controlling the multimedia driver board 3, the display screen 2, and the speaker; the audio output module is used to output audio signals; the USB module is responsible for charging and data The 5GNR broadcast module is used to play broadcast audio signals; the environmental adaptation module uses artificial intelligence algorithms to automatically adjust the color saturation and interface style of the display screen 2 based on the ambient light color temperature and home main color monitored by the micro-spectral sensor, to ensure that the visual performance of the device is dynamically integrated with the surrounding environment. For example, when it is detected that the space is dominated by wooden furniture, the display screen 2 will automatically switch to a retro filter and apply a wood texture border special effect.

[0024] In a specific embodiment, the base station mainboard 4 is fixed to the mounting plate by bolts. The base station mainboard 4 is a printed circuit board. The base station mainboard 4 is provided with a digital certificate module, a communication channel allocation module, an emergency mode module, a base station energy consumption optimization module, a 5G module, a 4G module, a first WIFI module, a network monitoring module, a network access module, a time synchronization module, a second PLC module, a baseband module, a multi-base station collaboration module, a home device control module, and a full-band antenna; The digital certificate module, the communication channel allocation module, the emergency mode module, the base station energy consumption optimization module, the 5G module, the 4G module, the first WIFI module, the network monitoring module, the network access module, the time synchronization module, the baseband module, the multi-base station collaboration module, the home device control module, and the full-band antenna are all electrically connected to the second PLC module. The second PLC module is used to control the base station mainboard 4. The digital certificate module is used to store the security authentication digital certificate. The communication channel allocation module allocates the communication type and communication channel according to the type of device connected. The emergency mode module is used to turn on the emergency mode. The base station energy consumption optimization module optimizes the base station energy consumption according to the algorithm. The 5G module is used to expand the 5G signal coverage range. The 4G module is used to expand the 4G signal coverage range. The first WIFI module is used to expand the WIFI signal coverage range. The network The monitoring module is used to monitor network status and data traffic, the network access module is used to access the Internet, the time synchronization module synchronizes timing information by tracking the ground 1588v2 link and provides a clock signal for the base station mainboard 4, and the baseband unit implements high-level signaling processing and OM functions of the base station system; the multi-base station collaboration module can coordinate the work of multiple base station devices in the home, and realize the reasonable allocation of resources between base stations through smart contracts.

[0025] The communication channel allocation module allocates communication types and channels. For example, fixed devices such as air conditioners and color TVs are connected via WIFI, while mobile devices such as sweeping robots and wearable devices use 5G connections because they may cross routers and cause signal interruption. In addition, the communication channel allocation module also divides exclusive communication channels according to the communication needs of the devices, including high-priority security data channels, low-latency control command channels, and large-bandwidth video streaming channels. The high energy consumption characteristics of traditional 5G base stations (especially in the millimeter wave band) may increase household electricity consumption. For this reason, the base station energy consumption optimization module adopts a reinforcement learning model based on Q-learning. The transmission power is dynamically adjusted based on historical energy consumption data. For example, sleep mode is enabled at night to reduce base station energy consumption, and an instantaneous response is provided when the device wakes up. In sudden disasters such as fires and earthquakes, traditional communication networks may fail due to power outages or base station damage, causing the home security system to be paralyzed. The emergency mode module turns on the emergency mode. Through the disaster-resistant redundant design of the 5G module (such as satellite return links and temporary drone base stations), the backup channel can be quickly activated when the traditional communication network is interrupted. Smart home devices (such as cameras, temperature and humidity sensors) are used to collect environmental data in real time. For example, the base station can automatically switch home devices to low-power emergency mode to extend the device life and assist rescuers in locating trapped people.

[0026] In a specific embodiment, the front shell 1 is made of ABS+PC engineering plastic material and is surface-treated by frosting and water transfer printing processes; the front shell 1 is composed of a rectangular front cover plate and arc-shaped connecting parts on its four edges; a rectangular through opening is provided on the front cover plate, and the display screen 2 is embedded in the opening; the inner edge of the opening is designed to be a bevel, and the arc-shaped connecting part is provided with a bolt hole, which is connected to the rear shell 5 by bolts; the rear shell 5 is fixedly connected to the arc-shaped connecting part of the front shell 1 by bolts, and a plastic support foot is provided at the bottom of the rear shell 5. A plurality of gradient heat dissipation hole arrays are provided on the rear shell 5, and the aperture gradually changes from 2mm in the center to 5mm at the edge. A speaker compartment is provided on the inside of the rear shell 5, and the speaker is placed in the speaker compartment. The speaker is electrically connected to the multimedia driver board 3 for playing audio; an electrical A battery compartment, in which an energy storage battery is arranged, is provided with a battery compartment, and the energy storage battery is electrically connected to the multimedia driver board 3 and the base station mainboard 4 to supply power to the multimedia driver board 3 and the base station mainboard 4; a USB interface and a TF card slot are provided on the rear shell 5, and the USB interface is electrically connected to the energy storage battery and the multimedia driver board 3. External audio, video and electronic photos can be stored in the storage module through the USB interface, and the external power supply can also be connected to the energy storage battery through the USB interface to charge the energy storage battery. The TF card slot is electrically connected to the storage module, and the TF card slot expands the storage capacity of the storage module by inserting a TF card; a support plate 6 is provided at the lower middle position of the outer side of the rear shell 5, and the support plate 6 is connected to the rear shell 5 by a hinge, and the shell stands on a plane through the adjustable support plate 6. The support plate 6 is also provided with an opening, and the hook passes through the opening to fix the shell to the wall.

[0027] In a specific embodiment, the display screen 2 can be switched to multiple modes by operating the touch layer. These modes include electronic album mode, date and time mode, advertising mode, control mode, music mode and broadcast mode. The electronic album mode will display stored photos in sequence; the advertising mode plays advertising videos transmitted through the network; the music mode plays stored music files; the date and time mode displays the current date and time, and displays the base station status, displays the radiation value in real time, and displays the real-time radiation value comparison in the form of a chart, such as the comparison with Wi-Fi and Bluetooth devices, to help users eliminate misunderstandings about radiation in a digitized way; the control mode allows the user to control the operation of the base station, configure the new base station startup and modify the basic information of the base station, turn on or off 4G and 5G cells and WiFi hotspots, and configure the frequency band of the 5G signal and the strength of the 4G and 5G signals, and adjust settings such as brightness and volume; the broadcast mode is used to play the content of the 5GNR broadcast module, and supports switching different broadcast channels through touch layer operations.

[0028] In a specific embodiment, when a multimedia device with a mobile communication base station is running, several multimedia devices with mobile communication base stations constitute a base station system covering the entire application environment. Each base station device in the network not only monitors the connection requests of other devices in real time, but also initiates a network connection request to the communication device connected to itself as a client at any time. Each base station device encapsulates the data to be sent into a data packet, which encapsulates the data packet type and encrypts the encapsulated data with the public key in the digital certificate stored in the digital certificate module in the device. When the base station device receives the data, it decrypts the encapsulated data with the public key in the digital certificate stored in the digital certificate module in the device, and unpacks the data packet according to the data packet type.

[0029] In today's society, modern home users have a psychological demand for "technological invisibility" for smart devices - that is, technical functions need to be naturally integrated with the living environment to avoid exposing sensitive components and causing anxiety. Multimedia devices, as home decorative devices, naturally have visual affinity, and their appearance design is highly adapted to the home environment. They can effectively conceal the "technical attributes" of the base station and reduce users' direct perception of radiation sources.

[0030] Users' preference for multi-functional devices can offset their perceived risks of single-function devices. The combination of multimedia devices and base stations not only provides network coverage, but also enables functions such as family photo album carousel, environmental sensor data display (temperature and humidity), and smart home control panel through the screen. This "one device, multiple functions" design gives the device additional value, diverts users' attention from base station radiation, and forms a psychological compensation effect. For example, users may pay more attention to the convenience and decorativeness of electronic photo frames rather than the implicit communication module, thereby reducing resistance.

[0031] By combining home base stations with multimedia devices, through the dual paths of "technical camouflage" and "psychological comfort", not only the contradiction between indoor coverage quality and equipment aesthetics is resolved, but also users' excessive concerns about base station radiation are more targeted and alleviated; the decorative attributes of electronic photo frames reduce the sense of technological intrusion, multi-functional integration shifts risk concerns, and visual data rebuilds user trust through transparent communication. This design is in line with the "invisible service" trend of smart homes, and provides operators with innovative solutions to break through users' psychological defenses and accelerate the popularization of home micro base stations.

[0032] The present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
