5. A method for optimizing a CPE network according to claim 3, wherein the comparing with a preset state threshold value determines whether the CPE needs to perform network mode switching, specifically comprising:
if the CPE is in the limited network mode, judging whether the CPE needs to switch the first network mode or not by comparing the second delay value with a preset second delay value threshold;
if the second delay value is greater than a preset second delay value threshold, the CPE needs to switch the first network mode.
6. The CPE network tuning method of claim 1, wherein the switching the network mode of the CPE to the second network mode by a preset network switching rule specifically includes:
determining a second network mode switched by the CPE according to the priority of the network mode preset by the CPE;
and deleting the relevant route and firewall rules of the first network mode where the CPE is located, and adding the relevant route and firewall rules of the second network mode to enable the network mode of the CPE to be switched to the second network mode.
7. The CPE network tuning method of claim 6, wherein the switching the network mode of the CPE to the second network mode by a preset network switching rule further comprises:
and if the first network mode is a WiFiStation network mode, disconnecting the WiFi AP connected with the CPE.
8. The CPE network tuning system is characterized by comprising a detection module, a judgment module and a switching module;
the detection module is used for detecting the network state of the CPE according to a first network mode in which the CPE is currently located;
the judging module is used for comparing the network state with a preset state threshold value to determine whether the CPE needs to switch network modes or not;
the switching module is configured to switch the network mode of the CPE to a second network mode according to a preset network switching rule if the CPE needs to switch the network mode.
9. The CPE network tuning system of claim 8, wherein the detection module comprises a mode unit and an acquisition unit;
the mode unit is used for acquiring network data corresponding to the CPE in the first network mode in real time through a preset monitoring program according to the first network mode, and detecting the network state of the CPE according to the network data;
the acquisition unit is used for acquiring RSRP and RSSI values of the current environment of the CPE and detecting a first delay value by using a ping program of an ICMP protocol in real time if the CPE is in an operator network mode and a WiFi Station network mode; if the CPE is in the wired network mode, a second delay value is detected by a ping procedure using ICMP protocol.
10. The CPE network tuning system of claim 8, wherein the switching module comprises a determining unit and a switching unit;
the determining unit is used for determining a second network mode switched by the CPE according to the priority of the network mode preset by the CPE;
the switching unit is configured to switch the network mode of the CPE to the second network mode by deleting the relevant route and firewall rule of the first network mode where the CPE is located and adding the relevant route and firewall rule of the second network mode.
