[0071] Figure 5 This is a schematic diagram of the device function acquisition apparatus provided in the embodiments of this application. Detailed Implementation

[0072] To better describe the technical solutions in the embodiments of this application, relevant knowledge is introduced below.

[0073] In traditional mobile communications, operators deploy various types of base stations in licensed frequency bands to ensure users have seamless mobile communication services anytime, anywhere. With technological advancements, emerging terminal applications such as Extended Reality (XR) require increasingly higher transmission rates, leading to higher frequency bands, larger bandwidths, and greater base station density in mobile communications.

[0074] In particular, insufficient indoor capacity is often addressed by adding small base stations such as picocells (PICO) or distributed antenna systems (DAS). Overlapping cell coverage exacerbates energy consumption and interference problems, leading to high network construction and maintenance costs for operators. This necessitates frequent switching of base station equipment on and off to achieve energy savings, driven by the tidal effect of fluctuating network service demands. This presents a contradiction between idle equipment and high energy consumption, while repeated switching on and off of base stations can cause equipment malfunctions and increased failure rates.

[0075] Currently, access network nodes such as base stations and relays are pre-deployed. To address the issues arising from the dense networking of base stations, using a terminal (such as a mobile phone) as a Wi-Fi hotspot can be considered as a network node that can be switched on and off. Figure 1 This is a schematic diagram of the architecture of a terminal acting as a Wi-Fi hotspot in related technologies, such as... Figure 1 As shown, the terminal utilizes its own fully equipped WIFI module and mobile communication module to act as a data aggregation gateway to complete the parsing and forwarding of IP packets. On the one hand, it uses the mobile communication module to access the mobile communication network to obtain network connectivity, and on the other hand, it acts as a WIFI network access point to provide WIFI access for other communication devices.

[0076] However, in this mechanism, cellular network access and Wi-Fi access belong to licensed and unlicensed frequency bands, respectively, and data transmission is achieved through two independent sets of wireless access technologies. In unlicensed frequency bands, this loosely coupled approach to Wi-Fi access is only suitable for scenarios with low requirements for latency, reliability, and capacity; the security and real-time performance of network access are difficult to guarantee.

[0077] To address the aforementioned problems in related technologies, and with the increasing storage, computing, and processing capabilities of terminal devices, which can provide more communication resources and stronger communication capabilities, this application provides a method for acquiring device functions, a communication device, an apparatus, and a storage medium. The communication device, based on its own hardware processing capabilities, can acquire network-side node functions by downloading and loading software, flexibly expanding network capacity. Simultaneously, in authorized frequency band mobile communication wireless access networks, plug-and-play functionality is introduced according to user needs, extending network coverage through various on-network mobile communication terminal devices. It supports secure network access points for unified wireless access technologies, ensuring the real-time performance and security of network access.

[0078] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist.

The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN).

Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but this application embodiment does not limit the terminology.

Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) system, a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a Next Generation System, a Home evolved Node B (HeNB), a relay node, a Femto, a Pico, etc., and is not limited in the embodiments of this application.

[0083] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0084] Figure 2 This is one of the flowcharts illustrating the device function acquisition method provided in the embodiments of this application, such as... Figure 2As shown, the execution subject of this method is a communication device, such as a network access point device, a terminal device, or a relay device. This method includes at least the following steps:

[0085] Step 201: Access the network as a terminal in the authorized frequency band, perform the first authentication with the centralized control node on the network side, and report the device capabilities.

[0086] Step 202: Based on the first triggering condition, download the software used to load the network side node function.

[0087] Step 203: Based on the second triggering condition, load the software, obtain the network-side node function, and perform a second authentication with the network-side centralized control node.

[0088] Step 204: Provide communication services to other terminals within the coverage area of ​​the wireless signal of the network access point device under the authorized frequency band, acting as a network access point device.

[0089] Specifically, the communication device accesses the wireless communication network as a terminal in the authorized frequency band, performs the first authentication with the network-side centralized control node (CCN) and reports the device's capabilities; based on the first triggering condition, software is downloaded from the mobile communication network-side centralized control node or remotely, and this software is used to load the network-side node functions; based on the second triggering condition, the software is loaded, the network-side node functions are obtained, and a second authentication is performed with the network-side base station control node.

[0092] The first triggering condition refers to the triggering condition that prompts the communication device to download software and obtain network-side node functions. For example, it may be triggered based on user needs, or the communication device's hardware processing capabilities may support it as a network access point to provide network access or data transmission services to other devices, or the network side may use the communication device for identity authentication / authorization.

[0093] The second triggering condition refers to the conditions that trigger the loading of the software after the communication device has downloaded it. This could be automatic loading after download, or passive loading based on user needs. Setting the first and second triggering conditions enables the communication device to acquire network-side node functions in real time according to user requirements.

[0094] The first authentication occurs when the communication device accesses the network as a terminal, and the second authentication occurs when the communication device obtains network-side node functionality, ensuring communication security. Furthermore, performing these steps within the authorized frequency band ensures that both the communication device acting as a terminal and the communication device subsequently obtaining network-side node functionality support a unified wireless access technology.

[0095] After the communication device loads the software, obtains the network-side node function and passes the network-side authentication, it provides communication services to other communication devices (such as terminals) within the coverage area of ​​its wireless signal under the authorized frequency band as a network access point device, thus providing an implementation scheme for network access points under the authorized frequency band.

Communication-related network-side base station control nodes provide communication policies and parameters, such as protocol stacks, operating frequencies, bandwidth, and resource configurations. The protocol stacks can all adopt a service-oriented standard interface design for flexible combination.

[0109] Algorithm models and parameters refer to signal processing algorithms, resource scheduling algorithms, AI algorithms and training models, as well as related algorithm parameters.

For example, using a capability level index to represent equipment capabilities, where higher capabilities result in a larger index number, when the index value is greater than a threshold, it indicates that the equipment's capabilities support it becoming a network access point device.

[0172] ② The network side authenticates or authorizes the communication device. This is a means of ensuring communication security. The network side can decide whether to provide software download services based on the communication device's capabilities, user association information, and the current application scenario.

[0173] ③ Business requirement triggering. Business requirement triggering can be passively triggered based on user actions, such as turning on a switch in the terminal application layer settings. Alternatively, it can be actively triggered by the communication device after satisfying ① and ②, to obtain the network-side node function.

[0174] The device function acquisition method provided in this application embodiment allows communication devices to acquire network-side node functions by downloading and loading software, flexibly expanding network capacity. At the same time, in the authorized frequency band mobile communication wireless access network, plug-and-play functionality is introduced according to user needs, extending network coverage through various on-network mobile communication terminal devices, supporting secure network access points with unified standard wireless access technology, and ensuring the real-time performance and security of network access.

[0175] Optionally, the method further includes:

[0176] Based on the third triggering condition, the network-side node function is released;

[0177] The third triggering condition includes at least one of the following:

[0178] The equipment capability is reduced to the point where it no longer meets the preset conditions;

[0179] Business needs have changed;

[0180] The network side stops authenticating or authorizing the communication device.

[0181] Specifically, after the communication device acquires the network-side node functionality, it can release the network-side node functionality based on a third triggering condition. The third triggering condition includes at least one of the following:

[0182] ① The equipment capability has decreased to the point where it no longer meets the preset conditions. This means the communication equipment's capability has declined, and it can no longer support its function as a network access point to provide communication services to other terminals. For example, the communication equipment may enter energy-saving mode, have insufficient power, or be damaged.

[0183] ② The network side stops authenticating or authorizing the communication device. For example, the network side may suspend the authentication or authorization of the communication device due to the detection of a security risk.

[0184] ③ Changes in business requirements. Changes in business requirements can be triggered by the user, such as by turning off a switch set at the application layer; changes can also be caused by the termination of services, the relocation of communication equipment causing it to leave the coverage area, or the network side terminating the communication services provided by the communication equipment to the terminal.

[0185] Release methods can be divided into active release and passive release.

[0186] Active release, such as when the network side terminates the communication equipment to provide communication services to the terminal, when the switch set at the application layer is turned off by the user, when the communication equipment enters energy-saving mode, or when the communication equipment's services end.

[0187] Passive release, such as when the network detects a security risk and stops authenticating the communication device, when the communication device moves and leaves the coverage area, or when the communication device has insufficient power or is damaged.

[0188] The device function acquisition method provided in this application embodiment allows communication devices to acquire network-side node functions by downloading and loading software, flexibly expanding network capacity. At the same time, in the authorized frequency band mobile communication wireless access network, plug-and-play functionality is introduced according to user needs, extending network coverage through various on-network mobile communication terminal devices, supporting secure network access points with unified standard wireless access technology, and ensuring the real-time performance and security of network access.

[0189] The technical solutions of the embodiments of this application are further described below through several specific examples.

[0190] Example 1: A method for acquiring and releasing device functions is provided, applied to a terminal device, specifically including the following steps:

[0191] Step a: Access the network as a terminal within the authorized frequency band and report your own capabilities. At this point, the first identity verification is performed with the network side.

[0192] Step b: The network side provides software downloads for loading network-side node functions.

[0193] Step c: The terminal loads the software, obtains network-side node functions, performs a second authentication with the network side, and then acts as a network access point device in the authorized frequency band for its area.

[0194] Step d: As a network access point device, provide secure communication services to other terminals within its wireless signal coverage area.

[0195] Step e: When business needs change or equipment capabilities decrease, release the functions of network-side nodes and retain only the functions of ordinary terminals.

[0196] Example 2:

[0197] Figure 3 This is a second schematic flowchart of the device function acquisition method provided in the embodiments of this application, such as... Figure 3 As shown, the method includes at least:

[0198] Step a: UE1 accesses the mobile communication network as a terminal within the authorized frequency band, completes authentication with the core network, and reports its own capabilities. Nearby, there is another UE2 belonging to the same username, but UE2 is located in an area with weak base station signal coverage and cannot directly establish a connection with the mobile communication network. The user activates the network access point function switch of UE1 and sends an access request to the network-side centralized control node.

[0199] Step b: After receiving the access request sent by UE1, the network-side centralized control node completes the identity authentication and authorization of UE1 with the Home Subscriber Server (HSS), determines that UE1's device capabilities are matched and the usage scenario is safe and effective, approves the access request, and distributes the software.

[0200] Step c: After UE1 completes the software download, it automatically loads, acquires network-side node functions (partial base station functions), and performs new authentication with the network-side base station node, becoming the network access point UE1-AP.

[0201] Step d: UE1-AP broadcasts AP-RS to provide the measurement and synchronization information required for network access; UE2 initiates a random access procedure, accesses the network through UE1-AP, and UE1 provides resources for data transmission.

[0202] Step e: When UE1-AP leaves the area as the user moves, release the network-side node function and restore the function of a normal terminal.
