Description

Technical Field

[0001] The present invention relates to the technical field of broadband network construction, and is particularly applicable to a dedicated network implementation method based on a broadband core network. Background Art

[0002] In current broadband networks, including dedicated networks and home networks, there are situations where multiple people share export bandwidth and network resources, and the problems they bring are also very obvious. For example, when network traffic is at a peak, all users share the same bandwidth resources, which will lead to insufficient bandwidth, reduced network performance, and affected user experience. If there are certain applications or users in the network that occupy a large amount of bandwidth, it will also cause other applications or users to have a very poor network experience, such as causing video conferences to freeze and file transfers to slow down, which will lead to complaints.

[0003] At the same time, sharing network resources also poses considerable challenges to network administrators. Network administrators need to ensure that network resources are allocated reasonably, monitor network usage, and prevent abuse. They also need to take into account the different priority requirements of different departments or applications, which makes management extremely difficult. When a network failure occurs, multiple users or applications sharing network resources also place extremely high demands on locating and troubleshooting the network failure.

[0004] Furthermore, if appropriate isolation measures are not taken for shared network resources, data between different users may be inappropriately accessed, increasing the risk of privacy leakage, expanding network risks such as security vulnerabilities, virus infections, and malicious attacks, and making it difficult to accurately trace network violations. How to achieve that each user can customize their own dedicated network channel under one physical broadband resource and one Internet account, provide users with more refined high-quality and secure services, and improve operational management capabilities and efficiency has become an important direction for improvement. Summary of the invention

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The broadband core network BNC is a new type of network architecture for broadband networks. It is mainly responsible for access control, service management and traffic forwarding of broadband services, and adopts a forwarding and control separation architecture.

[0024] The broadband core network BNC includes the broadband core network control plane (BNC-CP) and the broadband core network user plane (BNC-UP). The broadband core network control plane (BNC-CP) includes the control plane functions (CTRL, UPMNG, ACC, etc.) of the traditional broadband network gateway (BNG), AAA server, DHCP server, as well as CDN control plane, intelligent business analysis (CAM) and other network elements to realize user access control, business management and other functions. The broadband core network user plane (BNC-UP) is mainly responsible for user business traffic forwarding and traffic control. According to the needs of business development, SAC / SAD network elements are deployed on demand to provide business intelligent perception and value-added services, and CDN resource pools are deployed to provide CDN services. The broadband core network BNC is managed by a unified BNC management and control system, which is responsible for the management and operation and maintenance of the BNC system, business status monitoring, alarm management, rapid fault location and demarcation, business configuration, etc.

[0025] Based on the broadband core network BNC, the access network operator completes the construction of the access network to realize the construction of fiber-to-the-home FTTH and related systems such as CP, UP, BSS, and OSS. And distributes it to home users' optical modems ONU. The home user's optical modem ONU completes the link connection between OLT and ONU through PON link layer registration and authentication. At this time, broadband Internet users can use PPPOE to perform dial-up authentication, that is, authentication of the basic account of the broadband line, and obtain public network IP or private network IP.

[0026] The private network described in the present invention is an implementation method for dividing a private network for each user individual based on the private network and the home network in the current broadband network.

[0027] The implementation method of a private network based on a broadband core network described in the present invention includes a personal private network management system; the personal private network management system is connected to the broadband core network control plane, BSS, OSS, and AAA system to realize the authentication, establishment, deletion, and change of the personal private network.

[0028] like Figure 1 As shown in the figure, the authentication process of the personal network is as follows: S1.1, the user enters the personal network management system through the machine APP, WeChat or other client software.

[0029] S1.2, the personal network management system reads the user's optical modem information and queries the OSS system to obtain the user's basic broadband account information.

[0030] The personal network management system obtains the basic broadband account information of users in the following ways: a) Pre-set QR code. The pre-set QR code is bound to the personal network management system and the broadband line user account. After the user scans the code on his mobile phone to enter the personal network management system, the user's broadband basic account information can be linked from the QR code.

[0031] b) After the user logs in to the personal network management system website, the personal network management system can read the user's optical modem information and query the OSS system (Operations Support System) to obtain the user's basic broadband account information.

[0032] The OSS system contains the terminal ID of the RMS system (which manages ONU, home / enterprise gateways and other terminals) and related information such as the user's broadband basic account, fiber-optic IoT lines and ports.

[0033] c) After the user logs in to the personal network management system website, he / she manually enters the basic account information of the user broadband that needs to be associated.

[0034] S1.3, after entering the personal network management system, the user fills in the personal network service information on the client and initiates an application to the personal network management system, including personal identity real-name information, self-set private account name, password, upstream and downstream bandwidth requirements, purchase duration (year, month, day, etc.) and basic account user name.

[0035] S1.4, the personal network management system queries the BSS system (business support system) to see whether the user's broadband basic account exists and activates it. If it does not exist or has not been activated, the user cannot apply for the personal network service and a failure message is fed back to the user.

[0036] S1.5, if it exists and is activated, the tariff is queried based on the personal network service information, and the feedback is sent to the client, and the user confirms the tariff.

[0037] S1.6, after the customer confirms, the personal network management system submits the payment confirmation to the BSS system.

[0038] S1.7, the BSS system starts the settlement process.

[0039] S1.8, after the settlement is completed, the BSS system will associate the personal network account with the user's broadband basic account.

[0040] The establishment of the personal private network is that the personal private network management system initiates the personal private network activation process to the relevant systems of the broadband core network control plane B NC-CP and the home gateway. Different personal users under the same basic account set up different virtual private channels (including the home gateway WAN port, LAN port, SSID, personal private network account and password, DHCP Server, etc.), including: S2.1, the personal network management system sends information such as the personal network account, personal network bandwidth attributes, and associated user broadband basic account to the AAA system and the RMS home gateway management system.

[0041] S2.2, the AAA system adds the bandwidth of the personal network to the bandwidth of the associated user broadband basic account, modifies the QoS attributes authorized for the user broadband basic account, increases the total bandwidth limit for the user broadband basic account, and sends the configuration to the BNC-CP, AAA, and RMS terminal management systems.

[0042] S2.3, establish a personal private network channel for individual users; including the uniquely corresponding associated channels between the bearer network, access network, and local area network. Specifically, S2.3.1, the RMS home gateway management system issues the configuration settings of the personal network account to the home gateway, such as adding a new WAN port (including parameters such as uplink and downlink rates), LAN port and parameters, SSID and parameters, private account and password, etc. The home gateway will feedback prompt information if the modification is successful or failed.

[0043] S2.3.2, the RMS home gateway management system issues instructions to the home gateway to create a unique double-layer VLAN, SSID and password for the personal network account. After successful creation, the unique SSID and password are sent to the user through the personal network management system.

[0044] S2.3.3, the broadband core network control plane CP generates a session ID for the personal private network account, and generates a user table entry with the generated session ID as the index. The user table entry contains the broadband core network user plane BNC-UP ID, the newly generated WAN port IP address in the user's home gateway (or ONU), the user MAC, double-layer VLAN information, bandwidth speed limit information, ACL information, policy routing and other information.

[0045] The broadband core network control plane CP sends the user table entry to the broadband core network user plane UP, and the broadband core network user plane UP converts the user table entry into a forwarding table entry capable of executing forwarding.

[0046] S2.3.4, set the bearer network forwarding table, the WAN port IP address of the home gateway and the LAN VLAN and SSID channel as mutually unique associated channels, so that individual users can start normal business communications. The success or failure of the creation of the above channels will feedback specific information.

[0047] S2.4, after that, the broadband core network CP sends a billing start message to the AAA server to start billing for the personal private network.

[0048] S2.5, the broadband core network UP periodically collects the traffic statistics of the personal private network and sends it to the broadband core network CP through the broadband core network CP-UP channel.

[0049] S2.6, the broadband core network CP sends the personal network traffic statistics to the AAA system, and the AAA system periodically sends the personal network traffic statistics to the personal network management system for the applicant to query.

[0050] The flowchart of establishing the personal private network is as follows: Figure 2 shown.

[0051] The deletion of the personal network refers to the removal of the association of the personal network on the user's broadband basic account, the reduction of the upper speed limit of the broadband core network control plane BNC-CP, and the deletion of the home gateway (or ONU) private WAN port, LAN port, SSID, DHCPServer and other connection information, including: S3.1. When a user initiates a termination application to the personal network management system through a mobile phone APP, WeChat or other client, or when the personal network duration expires, the personal network management system automatically initiates a termination application.

[0052] S3.2, the personal network management system checks whether the user's broadband basic account exists and has been activated; if it does not exist, it will feedback failure information to the user; if it exists, it will send a confirmation cancellation message to the user. The cancellation information includes information such as the remaining time.

[0053] S3.3, after the user confirms, the personal network management system submits the termination confirmation to the BSS system.

[0054] S3.4, after the BSS system returns successfully, the personal network management system sends a personal network link channel deletion instruction to the AAA system and the RMS home gateway management system.

[0055] S3.5, the AAA system deducts the bandwidth of the personal network from the bandwidth of the user's broadband basic account, modifies the QoS attributes authorized for the user's broadband basic account, changes the total bandwidth limit of the user's broadband basic account, and sends the configuration to the broadband core network CP.

[0056] S3.6, the broadband core network CP sends an instruction to the broadband core network UP, and the broadband core network UP deletes the personal network forwarding entry.

[0057] S3.7, the RMS home gateway management system deletes the home gateway private WAN port, LAN port, SSID, and DHCP Server configuration.

[0058] S3.8, the RMS home gateway management system issues a command to the home gateway to delete the unique double-layer VLAN, SSID and password settings and parameters created for the personal private network. Information is fed back if the above modification is successful or failed.

[0059] The deletion flow chart of the personal private network is as follows: Figure 3 shown.

[0060] The change of the personal private network refers to querying the associated data on the user's broadband basic account and modifying the upper speed limit of the corresponding WAN port of the broadband core network BNC-CP and the home gateway (or ONU), including: S4.1, the user initiates parameter modification to the personal network management system through the mobile phone APP, WeChat or other clients. The user fills in the changed personal network service information on the client, including the new upstream and downstream bandwidth requirements, purchase duration and associated user broadband basic account, and initiates an application to the personal network management system.

[0061] S4.2, the personal network management system queries whether the user's broadband basic account exists and has been activated; if not, a failure message is fed back to the client of the personal user; if it exists, the tariff is queried according to the changed demand and the tariff is confirmed to the user.

[0062] S4.3, after the user confirms, the personal network management system submits the payment confirmation to the BSS system.

[0063] S4.4, the personal network management system sends the personal network account and bandwidth attributes and the user broadband basic account to the AAA system and the RMS home gateway management system.

[0064] S4.5, the AAA system modifies the bandwidth of the user's broadband basic account, modifies the QoS attribute authorized for the user's broadband basic account, increases the total bandwidth speed limit for the user's broadband basic account, and sends the configuration to the broadband core network CP; the broadband core network CP sends the modification instruction to the broadband core network UP. The broadband core network CP will feedback information on whether the modification is successful or failed.

[0065] S4.6, the RMS home gateway management system issues modification configuration instructions to the home gateway, such as parameters such as the uplink and downlink rates of the corresponding WAN port, and parameters such as the air port rate corresponding to the VLAN port and SSID, etc. The change of the personal private network is completed.

[0066] The deletion flow chart of the personal private network is as follows: Figure 4 shown.

[0067] In the implementation method of the dedicated network based on the broadband core network described in the present invention, the home gateway can adjust (add, delete, modify) the settings of the WAN port, LAN port, SSID, DHCP Server, etc. in real time according to the requirements of the management plane, and its implementation method can be implemented by customized software and hardware, or by virtualization (NFV) and software definition (SDN). The user's private account name can be customized by the user, that is, the user sets a private account name, or the user's mobile phone number or WeChat account can be directly used. In addition, the home gateway in the method of the present invention includes LAN upstream gateways and home router products, and also includes passive optical network PON upstream gateways and router products.

[0068] Among them, the passive optical network PON covers gigabit passive optical network GPON, Ethernet-based passive optical network EPON, 10G EPON, next-generation NGPON (10G GPON and subsequent versions) and WDM PON (point-to-point passive optical network using wavelength division multiplexing technology), etc., and the specific implementation methods are consistent.
