However, the conventional mobile communication distributed coverage scheme has the following problems:

firstly, in the traditional scheme, the POI loss is large, so the coverage area is limited; when a leakage cable is adopted to cover scenes such as a tunnel and the like, due to the characteristic that the loss of the leakage cable is fixed, high power is wasted when the front-stage power is large, and power is unavailable when the rear-stage power is weak, so that the originally small power utilization rate of POI output is greatly reduced, the coverage distance of the system is reduced, and therefore, one station can be covered only by a plurality of active devices at different installation positions and POI combining points; in addition, the leakage cable is expensive, so that the problems of high construction cost and poor covering effect exist in the traditional solution;

The working principle of the mobile communication high-power distribution coverage system is as follows: it should be noted that, the high-power divider 400 may adopt the existing devices in the market, and therefore, the specific implementation process is not described herein, in this embodiment, after the power divider is used to divide the signal of the base station, the high-power divider 400 is used to amplify each path of signal separately, and compared with the method of directly amplifying the signal of the base station and then covering the signal by dividing paths, the method adopted can generally improve the signal power by more than 10dB, thereby greatly increasing the coverage area of the base station;

firstly, a core network transmitting terminal 100 transmits a network into a multi-mode base station 200, and the mode base station 200 receives a signal transmitted by the core network transmitting terminal 100; secondly, after the multi-set standard base station 200 receives the signal of the core network transmitting terminal 100, transmitting the signal into the POI300, then processing and separating the information in the signal transmitted by the standard base station 200 through the POI300, and after the POI300 processes and separates the information in the signal transmitted by the standard base station 200; secondly, after the POI300 processes and separates the information transmitted in the standard mode, the processed and separated signal is transmitted to the high-power distributor 400, the signal source is lifted by the high-power distributor 400, and the step S14 is performed after the high-power distributor 400 lifts the signal source; then, the high-power distributor 400 promotes the signal source signal and then enters the office device 500, collects and separates the signal service again through the office device 500, and then enters step S15 after data processing; finally, after data processing, the information source is transmitted through the optical line terminal 600, the information source is transmitted into the service distribution device 700 through the optical line terminal 600, and then the signal is transmitted to the signal receiving terminal through the service distribution device 700.

The mobile communication high-power distribution coverage system has the beneficial effects that: the service offloading device 700 is configured to offload mobile service data to a fixed network where a broadband network gateway is located according to a preset rule, and may specifically include the following three situations:

(1) analyzing the IP data of the mobile service data to contain address information, wherein the address information comprises a destination IP address, a destination port number, a source IP address and a source port number; matching the address information with a preset shunting rule field; if the matching is successful, the IP data packet is distributed to the fixed network, and if the matching is unsuccessful, the IP data packet is transmitted back to the core network of the mobile network.

(2) Analyzing the IP data of the mobile service data to include a destination IP address; and distributing the IP data packet of which the target IP address is the IP address corresponding to the preset domain name to the fixed network. For example, all mobile services accessing a specific domain name are offloaded to the fixed network. When the terminal accesses a certain specific domain name (such as a video website) through the URL, the service offloading device 700 records the IP address corresponding to the domain name, adds the IP address to the IP segment to be offloaded, and then, the subsequent data packet can implement IP-based service offloading.

(3) And when the data volume of the mobile service data exceeds a preset value, the mobile service data is distributed to the fixed network, so that the transmission pressure of the mobile network is reduced.

Since the transport layer protocol of the user plane data is the user datagram protocol, the transport layer protocol of the control plane data is the flow control transport protocol, and different physical ports are used by the service offloading device 700 for receiving the uplink data and the downlink data, different processing modes can be adopted for the uplink user plane data, the downlink user plane data, and the control plane data.

For the uplink user plane data meeting the offloading rule, the service offloading device 700 may offload the uplink user plane data into IP data packets and then offload the IP data packets to the fixed network. Users served by the indoor small base station are divided into two types: the home users with the indoor small base stations are the home users, and the users which are not provided with the indoor small base stations but are covered by the indoor small base stations of other homes. For the first class of users, because the family is deployed with broadband access and the users pay for the broadband access service, the mobile services of the first class of users are not suitable for recharging, and in order to avoid modifying the charging function of the mobile core network, the mobile service data of the first class of users can be distributed to the fixed network, thereby avoiding the difficulty of mobile service charging. The service distribution device 700 can selectively distribute the user data to the two networks, thereby improving the utilization rate of network resources and improving the network experience of indoor users.

For the downlink user plane data meeting the offloading rule, the service offloading device 700 needs to re-encapsulate the downlink user plane data into a data packet of a user plane GPRS tunneling protocol, send the data packet to the small indoor base station, offload the data packet to the mobile service of the fixed network, and the downlink data packet transmitted from the fixed network is an IP packet. The traffic offload device 700 needs to repackage it into GTP-U packets that the base station can recognize.

For the control plane data of the terminal user, the service offloading device 700 sends the control plane data to the core network in a direct transparent transmission manner. The service offloading device 700 sends control plane data of the terminal user (e.g., S1-C interface data in the LTE system) to the mobile core network in a direct transparent transmission manner, so as to complete normal authentication, registration, service initiation, and handover of the terminal, which is not different from a conventional mobile network. That is, no matter whether the user plane data is shunted or not, the control of the terminal user is still in the mobile core network

The forwarding and allocating device converges the wireless service data of the m connected indoor terminals, the wireless and wired convergence service data of the n connected home terminals, and the wireless and wired convergence service from the downlink port, and transmits the converged data to the office device 500 through the ODN, and the office device 500 separates the two services and transmits the separated services to the mobile core network and the fixed core network, respectively.
