Description

Technical Field

[0001] The present invention relates to the integration of a power bank and a portable WiFi, and specifically refers to an intelligent terminal and a network service collaboration system integrating a shared power bank and a portable WiFi. Background Art

[0002] Technical bottlenecks of shared charging equipment:

[0003] Existing shared power banks generally have the following technical defects:

[0004] Single function: It only provides one-way power output and cannot meet users' complex needs for mobile network access. According to the IDC 2023 report, 87% of users need to charge and access the Internet while on the go, but existing devices require different terminals to be rented separately, resulting in:

[0005] Comprehensive usage cost

[0006] Comprehensive usage cost = C charge +C WiFi ≥1.8C integrated

[0007] Static resource allocation: The charging power is fixed at 5V / 2A (Qi standard) and cannot be dynamically adjusted according to the device type. Experiments show that the charging efficiency for fast charging devices (such as mobile phones that support PD3.0) is only:

[0008] hour

[0009]

[0010] Lack of energy efficiency optimization: The charging module lacks a temperature compensation algorithm, and efficiency degradation in high temperature environments meets the following requirements:

[0011] hour

[0012] Δη(T)=0.15(T j -298) 1.2 (T j >318K)

[0013] Limitations of mobile network terminals:

[0014] Traditional portable WiFi devices (such as CN112_[xxxx]B and other solutions) have significant technical obstacles: energy dependence: they require external power or built-in battery power, but the battery capacity is limited by the size (typical value is 5000mAh), and the network service duration meets:

[0015]

[0016] Inefficient spectrum utilization: With a fixed frequency band access strategy (e.g., supporting only the 5 GHz band), channel capacity in densely populated scenarios drops to:

[0017]

[0018] Lack of service coordination: Network resource allocation is decoupled from user behavior. According to IEEE Trans. Mobile Computing measured data, the QoS fluctuation variance of traditional solutions is as high as:

[0019]

[0020] Technical gaps in system-level collaboration:

[0021] The existing research on the coordination mechanism of charging and communication has the following deficiencies:

[0022] Resource allocation fragmentation: Charging power P c With network bandwidth B w Independent optimization leads to the degradation of the Pareto front:

[0023]

[0024] Actual measurements show that the comprehensive utility loss of this scheme is:

[0025] ΔU=U opt -U sep ≥42.7%

[0026] Dynamic response hysteresis: Polling-based scheduling mechanisms (such as the RR algorithm) cannot adapt to burst traffic, and network switching delays meet the following requirements:

[0027] t handover =t detect +t process ≥230ms

[0028] Exceeds 3GPP URLLC standard (requires t handover ≤100ms)

[0029] Fault prediction is crude: Traditional solutions that rely on threshold alarms (such as voltage and current monitoring) have a false alarm rate as high as:

[0030]

[0031] The innovation dilemma of business model:

[0032] The existing itemized billing system has two contradictions:

[0033] Imbalance between user willingness to pay and user experience: According to the GSMA 2024 report, user price sensitivity for composite services meets the following requirements:

[0034] hour

[0035]

[0036] The contradiction between operator benefits and costs: Under the traditional itemized leasing model, the equipment deployment density must meet the following requirements:

[0037] hour

[0038]

[0039] This results in a 2.7-fold increase in cost per unit area:

[0040] However, there are three major obstacles to the implementation of existing solutions in the industry:

[0041] Lack of hardware adaptability of mathematical models: complex optimization algorithms (such as the Hessian matrix in Formula 2) cannot be solved in real time on embedded systems

[0042] Multi-physics coupling design gap: The impact of electromagnetic interference on charging efficiency has not been resolved (experimentally measured:

[0043] ΔP c =0.12P WiFi ·cos(2πf c t)

[0044] Incompatible standardization systems: There is a timing conflict between the existing charging protocol (Qi / WPC) and the network protocol (802.11ax), resulting in:

[0045]

[0046] Therefore, there is an urgent need on the market for a better intelligent terminal and network service collaboration system that integrates shared power banks and portable WiFi. Summary of the Invention
