Description

Management method and device for realizing VOIP service zero configuration in POL

Technical Field

The invention relates to the technical field of passive optical networks, in particular to a management method and a device for realizing zero configuration of VOIP (voice over internet protocol) service in POL (polar intelligent control).

Background

A passive Optical Network system generally consists of an Optical Line Terminal (OLT) and an Optical Network Unit (ONU). The system can be applied to an enterprise network and provides Ethernet layer two services for the enterprise network, and is called POL (passive Optical LAN). In the system of POL, OLT is responsible for providing convergence and distribution of two-layer services at the core network side, and ONU is responsible for providing access and convergence of two-layer services at the user side. Meanwhile, in an enterprise network, the ONU device is usually required to support a voip (voice over Internet protocol) function.

Voip (voice over Internet protocol) is a voice call technology that achieves voice calls and multimedia conferences via Internet Protocol (IP), i.e., communication via the Internet. Other informal names are IP phone (IP telephony), Internet phone (Internet telephony), broadband phone (broadband telephony) and broadband phone service (broadband telephone service). Common protocols (Control protocols) for VOIP include h.323, SIP, RTP, etc. The ONU completes registration, session negotiation, conversation and the like with the VOIP server through the protocols. However, it is necessary to configure the VOIP module inside the ONU to work, and currently, the configuration of the key parameters related to VOIP reaches more than 10, which mainly includes: username, phone number, password, voice server address and port, voice foreign agent server address and port, mapping rules, registration period, encoding format, other service enabling switches such as call forwarding, abbreviated dialing, three-way calling, etc. It becomes a difficult problem how to quickly and efficiently configure VOIP traffic for hundreds or even thousands of ONU devices in a POL with so many configurations.

At present, in a passive optical network system, there are 3 ways to configure and manage an ONU, and the first is that an OLT can manage a suspended ONU device through an omci (ONU Management and Control interface) protocol. The format and flow of the OMCI protocol is defined by the ITU-T g.988 specification. The second is that the ONU interacts with a remote ACS (auto Configuration server) server in real time through a TR069 protocol, and receives various configurations issued by the ACS. The third is that the ONU is configured in a WEB page management manner.

With respect to the first configuration scheme through OMCI, the main problem in POL system is that it has to pay a lot of labor and time to set VOIP configuration for each ONU at the management platform of OLT, even many OLTs can only manage configuration through Shell command. And the different commands used by the OLT of each company are different, which undoubtedly increases the difficulty of operation and maintenance greatly. For the second configuration scheme through TR069, it is also necessary to operate each device on the ACS management platform, which is labor-intensive, and a special server host is also required as the ACS server, which also greatly increases the cost. For the third scheme of configuration through a WEB mode, the installation efficiency of the installation and maintenance personnel is greatly reduced, and the operation and maintenance personnel must carry one computer to the site to configure if one thousand pieces of equipment exist, which wastes time and labor. In the current POL networking system, how to perform service configuration quickly and efficiently by hundreds of devices becomes a problem that each ONU manufacturer must solve.

Example one

Fig. 1 is a flowchart illustrating a management method for implementing zero configuration of VOIP service in POL according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a management method for implementing zero configuration of VOIP service in POL, where the method includes:

step 110: according to VOIP service configuration, obtaining configuration classification, wherein the configuration classification comprises fixed uniform configuration, user authentication information configuration and external environment related configuration, the fixed uniform configuration is default configuration in which all ONU passive optical networks can be the same and cannot be modified after one-time configuration, the user authentication information configuration is user personal information, and the external environment related configuration is configuration influenced by external network topology environment.

Specifically, VOIP service configurations are very complex, and there are nearly hundreds of VOIP configurations, which are classified into detailed configurations, in this embodiment, the VOIP service configurations are classified into three major categories, namely, fixed unified configuration, user authentication information configuration, and external environment related configuration according to the type of the VOIP service configuration, where the external environment related configuration refers to configurations affected by the external network topology environment, such as VOIP server addresses and ports, external proxy server addresses and ports, and the user authentication information configuration refers to user telephone numbers, passwords, and the like. The fixed unified configuration refers to a default configuration in which all ONUs can be the same and are not modified substantially at a later stage after one configuration. Different configuration schemes will be adopted for these 3 configuration class features. In addition, the VOIP server in the POL uses an internal private server, so the user's phone number password is freely configurable.

Step 120: and respectively executing corresponding configuration methods according to the configuration classification, wherein the configuration methods are methods capable of automatically generating or acquiring the configuration, and the configuration methods are methods capable of automatically generating or acquiring the configuration.

Specifically, according to configuration types, different configuration methods are used for different types of configuration characteristics, corresponding configurations are automatically generated or obtained inside all configured ONUs, nearly hundreds of complex service configurations are converted into three types of configurations, the difficulty in maintenance is greatly reduced, the VOIP configuration of the ONUs is separated from the control of the current complex OLT OMCI command and the control of various configuration servers, zero configuration is achieved, the ONU maintenance efficiency is improved, maintenance personnel do not need to care about how to use VOIP service configuration commands of various OLTs, no bulky TR069 configuration servers are needed to be built, and all configurations inside the ONUs are automatically generated or obtained. Therefore, the technical problems that the VOIP configuration of the ONU is complicated and the installation and maintenance difficulty is high in the prior art are solved.

Further, the executing the corresponding configuration methods according to the configuration classifications, respectively, where the configuration methods are methods capable of automatically generating or acquiring configurations, and include: when the configuration type is fixed unified configuration, storing a fixed configuration file on an OLT (optical line terminal), wherein the first 12 bytes of the fixed configuration file contain a mark character string which is used for judging the type of the fixed configuration file; and downloading the fixed configuration file by utilizing the OMCI and operating.

Specifically, the fixed unified configuration ONU is realized by adopting a mode of issuing a configuration file by an OMCI (operation management interface), the principle is that downloading operation is executed by an OMCI Software Image ME, and the downloaded file is not an upgrade file but the configuration file. Because the configuration items are more and the configuration values of each device are the same, for example, switches, voice codes, figure maps and the like of some special services do not need to be modified under most conditions, the configuration method is simple and efficient in configuration, and only one configuration file needs to be stored on the OLT. A special mark character string is put in 12 bytes of a configuration file header, and when downloading is finished, the ONU judges whether the configuration file is an upgrade file or a VOIP (voice over Internet protocol) configuration file according to the 12 bytes of the file header.

Further, the executing the corresponding configuration methods according to the configuration classifications, respectively, where the configuration methods are methods capable of automatically generating or acquiring configurations, and include: when the configuration type is user authentication information configuration, reading an internal SN and an MAC address through the ONU passive optical network; obtaining a first character string according to the internal SN and the MAC address; automatically generating a user authentication configuration according to a first character string by using a formula C ═ EnCry (MD5(A), UserID), wherein A is the first character string, UserID is an ONU internal security code, and EnCry is a 3DES symmetric encryption algorithm; and storing the user authentication configuration C into an ONU internal database.

Further, the user authentication configuration C includes a user phone number and a user password.

Further, the user authentication configuration C is 24-digit characters, wherein the first 8 digits are the user telephone number, and the last 16 digits are the user password.

Specifically, for the independent variable configuration ONU, the configuration automatic generation is realized by adopting an SN + MAC address mapping mode. To ensure the security of the number to the outside, this mapping is implemented by an encryption algorithm. The whole process of configuration generation is as follows: firstly, reading an internal SN and an MAC address by the ONU, and splicing the internal SN and the MAC address to form a new character string A; and then, calculating and automatically generating a user authentication configuration by using a formula C ═ EnCry (MD5(A), UserID), wherein the UserID is an ONU internal security code, the EnCry is a 3DES symmetric encryption algorithm, the first 8 bits of C are taken as a telephone number, the last 16 bits of C are taken as a user code, and the user code is stored in an ONU internal database.

Further, the executing the corresponding configuration methods according to the configuration classifications, respectively, where the configuration methods are methods capable of automatically generating or acquiring configurations, and include: when the configuration type is the external environment related configuration, sending a DHCP Discover message by an Option60 field carried by an ONU passive optical network, and encrypting the Option60 field; the DHCP server receives the DHCP Discover message to carry out decryption authentication, and the VOIP user name password is analyzed; obtaining the address and the port of a voice server according to the VOIP user name password; acquiring a DHCP Offer message according to the voice server address and the port, wherein the DHCP Offer message is an Option120 field comprising the voice server address and the port; and analyzing and obtaining the address and the port of the voice server through an ONU passive optical network according to the DHCP Offer message, and distributing various server address information of the VOIP service.

Specifically, the external environment related configuration is realized by a scheme of redefining an Option field through a DHCP message extension technology, a DHCP client in an ONU carries a voice user name and a password for authentication through an Option60 (Vendor class identifier) when sending Discovery, and encrypts data of the ONU to ensure data security, and a DHCP server carries out decryption authentication on the message, and for an ONU device meeting the condition, the ONU device carries an Option120 in a DHCP Offer reply message to allocate various server address information configurations of VOIP services, and different account numbers can be allocated with different external proxy server addresses to cope with a complex voice server network environment which may be encountered. The whole configuration issuing process is as follows: 1, ONU carries Option60 to send DHCP Discover message; and 2, the DHCP server analyzes the VOIP user name and the password through the acquired message, and searches out the corresponding address and port of the voice server through the database. And 3, adding an Option120 field containing the address and the port of the server into the Offer message of the DHCP reply. And 4, the ONU resolves the Option120 field to obtain the address and the port of the VOIP server. Thereby, the acquisition of the external environment related configuration is realized. The invention also realizes the function of manually modifying the number through special dialing. The requirement that a special number is required for some telephones with special meanings can be met. The ONU can judge that the dialing prefix is an action of modifying the number by identifying the special dialing prefix such as # # #, the number after the prefix is stored in an internal database of the ONU, the VOIP registration is initiated again, and operation and maintenance personnel only need to add the number on a VOIP server.

The data message format of the Option60 is as follows:

name of field	Length of	Content providing method and apparatus
			Code	8	Fixed value 60
Length	8	Length of the whole message
			Enterprise Code	16	Enterprise code
Field Type	8	Extended attributes
			Field Length	8	Extended field length
Field Value		Authenticating encrypted information

The fields for Option120 are defined as follows:

name of field	Length of	Content providing method and apparatus
			Code	8	Fixed value 120
Length	16	Length of the whole message
			Enc	8	Encoding format (unused)
Data		Data of

Further, the sending of the DHCP Discover message through the ONU passive optical network carrying the Option60 field and the encrypting of the Option60 field include: the ONU passive optical network obtains automatically generated VOIP account information from a database, wherein the VOIP account information comprises a user account and a password; obtaining a generation time; obtaining a ciphertext through an encryption algorithm according to the user account and the password; and according to the generation time and the ciphertext, the ONU passive optical network generates encryption information and encrypts the Option60 field.

Specifically, when sending Discovery, a DHCP client in an ONU carries a voice user name and a password through an Option60 (Vendor class identifier) to perform data encryption as follows: the ONU reads the information of the VOIP account generated automatically from the database: user account (UserID), Password (Password). The user account here refers to a telephone number. And 2, generating a time stamp T by the ONU, wherein the T is defined as a 64-bit integer which is 0 seconds away from the Greenwich mean time in 1970, and forcibly converting an 8-byte long integer, such as complementing 0 when the number of bits is not high enough. 3. And F, splicing the user name and the Password into F ═ UserID + C + Passsword, wherein C is a special character such as a semicolon. The ciphertext SEC is generated as Hash (f), Hash () being a Hash algorithm, here defined as MD 5. 4. With the generation timestamp T and the ciphertext SEC, the ONU generates authentication encryption information field value T + SEC. The data security is ensured by encrypting the data carrying the voice user name and the password.

Further, after the address and the port of the voice server are obtained through the ONU passive optical network analysis, the method includes: and the ONU passive optical network stores the address and the port of the voice server to an internal database and initiates voice registration to the VOIP server.

Specifically, the format of the Data field in the field of the Option120 is a configuration name colon configuration value, such as address: 192.168.8.8; port: 5060, a heat-insulating material; and the ONU analyzes the configuration in the Option and stores the configuration in an internal database and initiates voice registration to the VOIP server.

The embodiment of the invention can meet the rapid and efficient VOIP service construction and various scenes with complex configuration requirements by refining and classifying the configuration, each type of configuration is automatically generated or obtained by a respective special configuration method, zero configuration is realized, a maintainer does not need to care how each ONU device configures the VOIP service, the assembly and maintenance efficiency is greatly improved, the labor cost is greatly reduced, the VOIP service is almost ready-to-use and has strong expansibility for the whole POL, the VOIP configuration of the ONU is separated from the current fussy OLT OMCI command control and the control of various configuration servers so as to realize zero configuration, the ONU assembly and maintenance efficiency is improved, the maintainer does not need to care how to use the VOIP service configuration commands of various OLTs and does not need to build a bloated TR069 configuration server, thereby solving the problem that the VOIP configuration of the ONU in the prior art is fussy, the technical problem of high assembly and maintenance difficulty.
