Policy library based pico site access method

Abstract

A method for picosite access based on a policy library includes the following steps: Step 1) initializing the picosite request address; Step 2) receiving the picosite connection request; Step 3) parsing the picosite request information; Step 4) searching the picosite access policy library; and Step 5) setting a new request address for the picosite. In Step 4), the corresponding accessible OMC node's request address, RequestUrlomc, is searched in the picosite access policy library based on the picosite information. The mapping relationship of the picosite access policy library construction method is: (picosite information) -> (RequestUrlomc). In Step 5), the initial instance of the access node, OMC init, returns and sets the picosite request address, RequestUrlomc. After receiving RequestUrlomc, the picosite updates its request address. Subsequent communication between the picosite and the OMC uses the updated connection address, RequestUrlomc. The application of this method can not only reduce the pressure on gateway traffic but also enable personalized access for picosites, such as small-batch testing and rolling upgrades.

Description

Technical Field

[0001] This invention belongs to the field of computer network communication technology, specifically a picosite access method based on a policy library. Background Technology

[0002] With the rapid development of mobile internet, users' network needs are ubiquitous, thus placing higher demands on the mobile communication networks of telecom operators. To meet customer needs, telecom operators generally use macro base stations for basic coverage and deploy low-power base stations in key and important scenarios to fill in coverage gaps; the low-power base stations mentioned here are picocells.

[0003] The implementation architecture of the picostation differs from the proprietary and closed technical systems of traditional equipment manufacturers. Instead, it adopts an open and standardized technical architecture. For example, the connection between the picostation and the Operation and Maintenance Center (OMC) uses the TR-069 related system for interconnection and communication.

[0004] The basic idea of ​​the TR-069 protocol is to utilize the RPC remote procedure call protocol method based on the Simple Object Access Protocol (SOAP), which is widely used in next-generation web services. Its session protocol uses the HTTP 1.1 protocol, which is a request-response C / S service model. The Pifi station is equivalent to the client side, and the OMC is equivalent to the server side.

[0005] The client / server (C / S) service model between Pifly Station and OMC differs from that of the traditional internet. The traditional internet experiences low uplink traffic and high downlink traffic under pressure from a unified gateway (GW), necessitating CDN traffic distribution. Generally, this model achieves traffic distribution by forwarding traffic from the unified gateway GW to CDN nodes.

[0006] In the current network, the connection between picosites and the OMC is built using a traditional internet-like model. Generally, the request URL of a picosite is set to the fixed gateway (GW) address. Because picosites generate large uplink traffic and their numbers are constantly increasing, the fixed gateway (GW) frequently crashes. This configuration also makes upgrading the fixed gateway (GW) difficult; if an upgrade is needed, the gateway service must be stopped, which in turn affects all picosite devices in the network, resulting in poor flexibility and scalability. Summary of the Invention

[0007] To address the aforementioned problems in existing technologies, this invention provides a picosite access method based on a policy library. The basic idea of ​​this method is to achieve uplink traffic splitting by dynamically modifying the gateway (GW) request address (RequestUrl) of the picosite; that is, setting different request addresses for the picosite according to different policies. This method not only reduces the pressure on gateway traffic but also enables personalized access for picosites, such as small-batch testing and rolling upgrades.

[0008] The steps of the method of the present invention include: step 1) initializing the picosite request address; step 2) receiving the picosite connection request; step 3) parsing the picosite request information; step 4) searching the picosite access policy library; and step 5) setting a new picosite request address.

[0009] In step 4), the corresponding RequestUrl of the accessible OMC node is searched in the picosite access policy library based on the picosite information. omc The mapping relationship for the construction method of the Pifly Station access strategy library is: (Pifly Station information) —> (RequestUrl) omc ); In step 5), the instance OMC of the first access node. init Return to the RequestUrl for setting the Pifly site omc Pifly Station received RequestUrl omc Then, update the picosite request address; subsequent communication between the picosite and the OMC will use the updated connection address RequestUrl. omc To conduct communication.

[0010] Specifically, in step 4), the information of the Pico station includes: IP address, device serial number (SN), device model (EquipmentType), device manufacturer (Vendor), software version (SoftVersion), and / or protocol version (ProtocolVersion).

[0011] Therefore, in step 4), the mapping relationship of the construction method of the picostation access strategy library is as follows: (IP, SN, EquipmentType, Vendor, SoftVersion, ProtocolVersion)—>(RequestUrl omc ) Among them, IP, SN, EquipmentType, Vendor, SoftVersion, and ProtocolVersion can be added or removed according to actual needs, and the priority of the policy is marked by the numerical Priority field. The higher priority policy is executed first.

[0012] The strategy in step 4) is: Based on the condition SoftVersion=V2.01, the nodes in the backend OMC cluster are returned as OMC. SoftVersion Request URL omc_softversion Its strategy priority is 1. Or, Based on the regional IP address range and the device manufacturer (Vendor), the system returns the nodes in the backend OMC cluster as OMC. new Request URL new Its strategy priority is 2. Or, The hash function value of the device serial number (SN) is moduloed, with the modulus being the number of OMCs in the cluster. The specific value of the modulus, i, represents the request URL (RequestUrl) returned to the i-th OMC in the cluster. omc_i Its strategy priority is 3.

[0013] The policy-based picosite access method of this invention can be applied to the initial connection of a picosite or to subsequent communication between the picosite and the OMC. The application of this method not only reduces the pressure on gateway traffic but also enables personalized access for picosites, such as small-batch testing and rolling upgrades. Attached Figure Description

[0014] Figure 1 This is a flowchart illustrating the method of the present invention. Detailed Implementation

[0015] The following is in conjunction with the appendix Figure 1 The present invention will be further described in detail with reference to specific embodiments.

[0016] The steps of this example's policy-based picostation access method include: Step 1) Initialize the picosite request address When launching a PIF website, use an LMT tool to uniformly set the request URL of the PIF website to RequestUrl. init It is powered on and started, and network connectivity between the Pico station and the OMC access node is ensured.

[0017] Step 2) Receive picostation connection request The OMC instance responsible for the initial node access in OMC init Accept the first connection request from the pico site, extract its request information RequestInfo, and call the pico site request information parsing module.

[0018] Step 3) Parse the Pico Station request information Based on the incoming RequestInfo request information, relevant fields are parsed, including the IP address of the picostation, device serial number (SN), device model (Equipment Type), device manufacturer (Vendor), software version (SoftVersion), protocol version (ProtocolVersion), etc., and the picostation access policy library is searched.

[0019] Step 4) Locate the Pifly Station access policy library Based on the PIF station's IP address, device serial number (SN), device model (EquipmentType), device manufacturer (Vendor), software version (SoftVersion), and protocol version (ProtocolVersion), search the PIF station access policy database for the corresponding RequestUrl that can access the OMC node. omc .

[0020] The recommended mapping relationship for constructing the preferred picosite access strategy library is as follows: (IP, SN, EquipmentType, Vendor, SoftVersion, ProtocolVersion)->(RequestUrl omc ) The IP, SN, EquipmentType, Vendor, SoftVersion, and ProtocolVersion can be added or removed according to actual needs, and the priority field is marked with a numerical value. The smaller the value, the higher the priority, and the higher priority policy is executed first.

[0021] For example: Strategy A: Based on the condition that the software version is SoftVersion=V2.01, return nodes in the backend OMC cluster that are OMC nodes. SoftVersion Request URL omc_softversion Its policy priority is 1, in order to enable the management of specific versions of Pifi Station to access specific OMCs.

[0022] Strategy B: Return nodes in the backend OMC cluster that are OMCs based on the regional IP address range and the device manufacturer (Vendor). new Request URL new Its policy priority is 2, in order to manage the access of new network equipment manufacturers' picosite stations to specific OMCs in a specific area.

[0023] Strategy C: The hash function value of the device serial number (SN) is taken modulo the number of OMCs in the cluster. The specific value of the modulo, i, represents the RequestUrl address returned to the i-th OMC in the cluster. omc_i Its policy priority is 3, which can realize the management of different picosite stations directly accessing the corresponding OMC, eliminating the need for gateway GW traffic splitting.

[0024] Step 5) Set the new request address for the Pifly site The first instance of the node to be connected is OMC init Return to the RequestUrl for setting the Pifly site omc Pifly Station received the RequestUrl omc Then, update its request address, and subsequent communication between the Pico station and the OMC will use the new connection address RequestUrl. omc It enables communication to achieve functions such as uplink traffic splitting, small-batch testing, and rolling upgrades.
