Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. The reference numerals in the present application are only used for distinguishing the steps in the scheme, and are not used for limiting the execution sequence of the steps, and the specific execution sequence controls the description in the specification.

First, an internet television service provided to a user by an operator is described, and The internet television service includes OTT TV (Over-The-Top TV) and IPTV. OTT TV and IPTV systems include the following three parts: a content broadcast control platform, a transmission network, a customized set-top terminal STB (Set Top Box). The OTT TV provides video-on-demand service for users through public Internet, and the IPTV provides video-on-demand service and multicast and live broadcast service for users through private network. In order to meet the user demand, OTT TV services need to be modified to IPTV services.

The transformation of OTT TV services into IPTV services may be achieved by:

(1) The maintenance personnel go up to upgrade the existing OTT TV set top box into an IPTV version.

(2) The set-top box is accessed to the LAN2 port (Local Area Network) of the home ONT (Optical network terminal) by the maintenance personnel through an independent network cable, and is accessed to the IPTV private network in a dialing way through a PPPOE (Point-to-Point Protocol Over Ethernet) or IPOE (IP over Ethernet) authentication mode.

Wherein, because OTT TV business and wide business share the Internet channel, set-top box television business and wide business public home ONT LAN1 port of the wide business are cut in; the IPTV service needs to be isolated from the broadband service channel, so that the IPTV service needs to be modified by connecting an independent network cable by adopting the scheme.

In addition, part of home ONTs have only one LAN port, and the home ONTs are updated before the OTT TV service is changed into IPTV, so that the original ONTs are changed into ONTs with multiple LAN ports. Moreover, if the home broadband access is in a fiber to the building FTTB (Fiber to The Building) mode, the fiber to the home FTTH (Fiber To The Home) needs to be modified first.

Therefore, the OTT TV needs to be moved to the IPTV mode to be on the door of the maintenance personnel, and consumes more manpower. In addition, in the reconstruction process, the home access network needs to re-lay the network cable, which often damages the home decoration environment of the user. And a part of families need to replace ONTs, the network transformation progress is slow and uncontrollable, and the single-user transformation cost is high.

For example, the number of Hunan mobile OTT TV users is 400 tens of thousands, and the number of IPTV users is 150 tens of thousands. The reconstruction cost of an individual user from OTT TV to IPTV is between 50-200 yuan. If the OTT TV service of the Hunan mobile OTT TV user is migrated to the IPTV service, the direct network transformation cost is 50 yuan x 400 ten thousand (user number) =more than 2 hundred million, the transformation time is more than 3 years, the improvement of the code rate of the television channel is restricted, the competitive advantage of the service quality is reduced, a large number of users are lost, and meanwhile, the network expansion cost is increased by 1.5-2 hundred million in the OTT code lifting process of a metropolitan area network, an access network and a broadcast control content platform.

In order to solve the problems in the prior art, an embodiment of the present application provides a method for accessing an IPTV network through OTT TV equipment, which is applied to a broadband access server BRAS, as shown in fig. 1a, and includes the following steps:

s11: receiving a tunnel establishment request sent by OTT TV equipment;

s12: distributing a tunnel ID to the OTT TV equipment according to the tunnel establishment request, wherein the tunnel ID is used for establishing a tunnel with the OTT TV equipment;

s13: receiving a session establishment request sent by the OTT TV equipment through the tunnel;

s14: establishing a session with the OTT TV equipment according to the session establishment request, wherein session information for establishing the session is determined by negotiation between the OTT TV equipment and a broadband access server BRAS;

s15: and sending IPTV service information to the OTT TV equipment through the session.

In the embodiment of the present application, the function development of the broadband access server BRAS (Broadband Remote Access Server) has a IGMP (Internet Group Management Protocol) +l2tp (Layer 2tunnel protocol) function, where the OTT TV device may be an OTT TV set-top box, and the set-top box has a pure L2TP dialing function based on an android framework development; the operator can remotely support through the production flow organization and reform the OTT TV service into the IPTV service through the steps under the condition that the user does not feel.

Referring to fig. 1b, the existing OTT TV service uses an internet channel, as indicated by the upper left Fang Dianxian dashed box in fig. 1 b. The IPTV service modified by the manual entry method is shown in the dotted line and dashed line box on the upper right side in fig. 1b, and the network channel is logically isolated from the internet service by manually connecting the network cable, and the physical port isolation is used on the subscriber ONT. The scheme provided by the embodiment of the application is shown in a dotted line and dashed line box at the lower part in the figure 1b, and based on a home wide network, the IPTV private network is accessed by using a tunnel to realize the over mode of the OTT TV set top box. Specifically, at an access point (OTT TV set-top box) of an IPTV service, two nodes of the access point (BRAS) of the IPTV private network establish a tunnel carrying the IPTV service, and the tunnel can be specifically established by using an L2TP tunnel technology. The scheme of establishing the tunnel between the home service access point and the private network access point does not change the home network or modify the operator network, and the OTT TV equipment can be accessed to the IPTV network by utilizing software modification, so that the upgrading modification from the OTT TV service to the IPTV service is realized.

For convenience of explanation, in the embodiment of the present application, the tunnel is constructed by using the L2TP technology. The tunnel is a network tunnel established through a tunneling technique, which is a way of transferring data between networks through an infrastructure using an internetwork. The data (or payload) communicated using the tunnel may be data frames or packets of different protocols. The tunneling protocol repacks the data frames or packets of these other protocols for transmission in a new packet header. The new header provides routing information to enable the encapsulated payload data to be transferred over the internet. The encapsulated packets are routed between the two endpoints of the tunnel over the public internetwork. The logical path that an encapsulated packet passes through as it passes over the public internet is called a tunnel. Once the network endpoint is reached, the data will be unpacked and forwarded to the final destination. Note that tunneling refers to the entire process including data encapsulation, transmission, and decapsulation.

The establishment of the L2TP protocol includes two phases of negotiation of the tunnel and negotiation of the session. In the embodiment of the application, the OTT TV device is used as LAC (L2 TP Access Concentrator), and the BRAS is used as LNS (L2 TP Network Server). In step S11, the OTT TV device sends a tunnel establishment Request SCCRQ (Start-Control-Connection-Request) to the BRAS, and carries information of the OTT TV device in a mode of Attribute-to-AVP (Attribute-Value Pair). After the BRAS receives the request, in step S12, the tunnel establishment request may be analyzed and checked, and if it is checked that the received tunnel establishment request packet conforms to the configuration of the home terminal, the BRAS will respond to the SCCRP and carry the corresponding AVP information and the tunnel ID information. After receiving the response of the BRAS, the OTT TV device may also send an SCCCN message characterizing the connection to confirm the establishment of the tunnel. At this point the tunnel between the LAC and the LNS has been established normally and agreed upon tunnel ID information.

After the establishment of the tunnel, the session is negotiated. In step S13, the OTT TV device first sends a session establishment Request ICRQ (including-Call-Request) to the BRAS end, where the session ID allocated by itself may be carried by AVP information, but the session ID in the header is 0 at this time. After receiving the session establishment request, the BRAS responds to an ICRP (Incoming-Call-Reply) message according to the received session establishment request in step S14, where the header carries the session ID sent by the OTT TV device, and the AVP carries the session ID of the BRAS end. Then, the OTT TV device may also respond to an ICCN (Incoming-Call-Connected) to confirm the session establishment and negotiate a successful session ID after receiving the ICRP message. Other information of some OTT TV devices, such as authentication information, may also be carried in the ICCN packet, so as to be used by the BRAS subsequently.

Through the scheme, the tunnel session can be established between the OTT TV equipment and the BRAS, so that the OTT TV equipment is accessed to the IPTV network, and the OTT TV service is modified into the IPTV service. By establishing the tunnel session according to the scheme, the IPTV advantages can be exerted, the multicast function can be used, and the delay is low. The upgrade can be realized by using the existing OTT TV equipment without the need of the service personnel to go to the door for installation and transformation, thereby effectively reducing the cost of manpower and material resources. Moreover, the scheme provided by the embodiment can be suitable for any home networking, and can be widely applied to various application scenes. In addition, through the scheme provided by the embodiment of the application, unicast data transmission service is used between the OTT TV equipment and the BRAS, and multicast transmission service is used between the BRAS and the multicast source, so that the pressure of the network and the platform above the BRAS can be relieved.

The following describes an IPTV network structure obtained by manual entry installation and an IPTV network obtained by modification of the scheme provided in this embodiment by comparing with the drawings. Fig. 1c shows a structural diagram of an IPTV network obtained by manual entry installation retrofit, wherein the IPTV is physically isolated from a home wide dual channel home access side. Fig. 1d shows a network structure diagram of an access IPTV private network of an OTT TV device according to the solution provided by the embodiment of the present application, where the IPTV and the home broadband share a channel, and the service Overlay network is networked through an L2TP technology.

The method can realize the effects that maintenance personnel do not need to go to the gate, the home access network does not need to be modified, the home ONT does not need to be replaced and the modification progress is controllable in the migration process from the OTT TV to the IPTV. By remote upgrading of OTT TV set top box software version, the set top box can start up to automatically dial L2TP VPN to access IPTV private network. Taking the existing 400 or more ten thousand OTT TV users in Hunan as an example, through the scheme provided by the embodiment, the migration of the total users can be completed within about 4-6 months, the network transformation cost and the network expansion cost are saved by 3.5-4 hundred million, the channel code can be quickly realized by the IPTV service after transformation, the live television broadcasting requirement of the users is met, and the competitiveness of the television service quality is improved.

Optionally, based on the solution provided in the foregoing embodiment, the tunnel establishment request includes identity information of the OTT TV device;

step S12, of allocating a tunnel ID to the OTT TV device according to the tunnel establishment request, as shown in fig. 2, includes the following steps:

s21: analyzing the tunnel establishment request to obtain the identity information of the OTT TV equipment;

s22: distributing tunnel IDs to the OTT TV equipment according to the identity information of the OTT TV equipment;

s23: and sending the tunnel ID to the OTT TV equipment to instruct the OTT TV equipment to establish a tunnel according to the tunnel ID.

The tunnel establishment request sent by the OTT TV device may include identity information of the OTT TV device. And for the analyzed identity information of the OTT TV equipment, the BRAS distributes a tunnel ID to the OTT TV equipment and sends the tunnel ID to the OTT TV equipment so as to establish a tunnel between the OTT TV equipment and the BRAS. By the scheme provided by the embodiment, the tunnel ID can be allocated and the tunnel can be established, and in practical application, an independent tunnel can be established for each OTT TV device so as to provide the required IPTV service for each OTT TV device.

Optionally, the tunnel establishment request further includes identity authentication information of the OTT TV device;

as shown in fig. 3, before allocating a tunnel ID to the OTT TV device according to the identity information of the OTT TV device in step S22, the method further includes the following steps:

s31: analyzing the tunnel establishment request to obtain the identity authentication information of the OTT TV equipment;

s32: performing authentication on the identity authentication information of the OTT TV equipment according to a preset authentication rule;

the step S22, which allocates a tunnel ID to the OTT TV device according to the identity information of the OTT TV device, includes:

s33: and under the condition that the authentication is passed, distributing a tunnel ID for the OTT TV equipment according to the identity information of the OTT TV equipment.

In the scheme provided by the embodiment, the OTT TV equipment can be authenticated in the process of establishing the tunnel. The L2TP authentication, like PPP authentication, can authenticate the tunnel by selecting an optional mode, and if tunnel authentication is configured, the attribute pair in the tunnel establishment request sent by the OTT TV device carries corresponding identity authentication information, so as to perform tunnel authentication. Specifically, the tunnel authentication can be performed according to whether the password information configured on both sides of the OTT TV device and the BRAS is the same, and because the BRAS and the OTT TV device can be configured with the same and fixed tunnel name and password, the tunnel authentication can be performed effectively when the tunnel is established.

Based on the solution provided in the foregoing embodiment, optionally, the session establishment request includes session identity information of the OTT TV device;

the step S14 establishes a session with the OTT TV device through the tunnel according to the session establishment request, as shown in fig. 4, and includes the following steps:

s41: analyzing the session establishment request to obtain session identity information of the OTT TV equipment;

s42: feeding back a session message to the OTT TV equipment according to the session identity information of the OTT TV equipment, wherein the session message carries the session identity information of the OTT TV equipment and the session identity information of a broadband access server BRAS;

s43: and receiving the session confirmation information fed back by the OTT TV equipment according to the session message.

The session identity information of the OTT TV device obtained by parsing in step S41 may represent the identity of the OTT TV device, and a session message is generated in step S42 according to the session identity information obtained by parsing. The header of the session message may carry the session ID sent by the OTT TV device, and the AVP carries the session ID of the BRAS end. Then, in step S43, after receiving the session packet, the OTT TV device may feedback session confirmation information to determine session establishment, and in addition, the confirmation information may further include information of other OTT TV devices, so that the BRAS may subsequently perform authentication or other operations. By the scheme provided by the embodiment, the session can be further established based on the established tunnel.

Optionally, based on the solution provided in the foregoing embodiment, step S42 includes feeding back, according to session identity information of the OTT TV device, a session packet to the OTT TV device, as shown in fig. 5, including the following steps:

s51: sending service identity authentication information to a service server according to the session identity information of the OTT TV equipment so as to instruct the service server to authenticate IPTV service rights of the OTT TV equipment;

s52: and after receiving the message representing that the IPTV service authority of the OTT TV equipment is passed by the service server, feeding back the session message to the OTT TV equipment.

In step S51, the BRAS may send the built-in L2TP username and password of the OTT TV device to the service server for authentication. The built-in L2TP user name and password of the OTT TV device may be included in session identity information sent by the OTT TV device. The service server can be an AAA server, in the verification process, the AAA server judges whether the user name and the password on the AAA server are consistent with the user name and the password of the OTT TV equipment, if so, the verification is successful, and the BRAS locally authenticates the tunnel. The authentication at the service server can realize the judgment of the user service authority of the OTT TV equipment, for example, judge whether the user has opened IPTV service, paid fee and the like, so as to realize the management of the user and provide service in a targeted manner.

The scheme is further described below in conjunction with two-layer multicast protocols IGMP and L2 TP. In the scheme of migrating OTT TV service to IPTV service, ONT is used as PPPOE user, firstly, it is necessary to go on line in BRAS equipment to obtain a user IP. An OTT TV device hangs down any interface of ONT, can be put on line by dialing L2TP to BRAS. When passing the ONT, the ONT can be used for converting the LAC tunnel source IP of the L2TP message header into the PPPOE user IP, the LNS IP in the OTT TV equipment is fixedly written in, the ONT is equivalent to NAT, and the passing messages are subjected to corresponding address conversion. Referring to fig. 6, when the bras device is used as an LNS and interacts with related protocol messages and data messages on the OTT TV device side, the messages have two-layer header, the PPPOE header on the outermost layer, and the L2TP header inside.

The following describes features of the scheme provided by the embodiment of the present application with reference to application scenarios:

the IPTV user obtained by the scheme transformation provided by the embodiment accesses a private network on the BRAS, belongs to a VPN and is completely isolated from a public network. In the application process, the ONT is used as a PPPOE user and is online in the BRAS equipment to acquire a user IP.

In the embodiment, the LAC function is supported by upgrading the OTT TV set top box remotely. The set top box performs L2TP dial-up and establishes a tunnel with an LNS (BRAS) side, and the LNS authenticates a user and distributes an IPTV private network IP.

After OTT TV equipment is accessed to an IPTV network through the scheme provided by the embodiment of the application, a multicast function can be realized. Taking the IPTV user to watch the live program as an example, the set top box as LAC takes the multicast channel to add and leave the message, encapsulates the outer PPPOE user head and the inner L2TP head, sends the messages to the LNS (BRAS), and then the LNS receives the messages and performs decapsulation treatment.

The LNS (BRAS) performs program authentication after receiving the group join information. After authentication is passed, the joining information is maintained, the inquiry message is sent periodically, the program on demand is kept alive, and multicast route entries are generated for drainage.

When the user no longer watches the live program, the set top box is used as LAC to send a group leave message, LNS (BRAS) receives the group leave message to carry out program authentication release, and multicast routing information is deleted.

Then, IPTV users are disconnected, LNS senses the disconnection of the users, releases the stored authentication result, deletes the group joining information of the users, and deletes the multicast route item.

Referring to fig. 7, the following describes in detail, with reference to an example, the flow of accessing the OTT TV device to the IPTV network through the scheme provided in the present embodiment:

firstly, a fixed L2TP tunnel name, IP, a secret key and an authentication mode are built in the L2TP protocol of the set top box, and the fixed L2TP tunnel name, IP, the secret key and the authentication mode are used for completing a tunnel establishment stage.

And then, the set top box L2TP protocol completes the session establishment through user authentication. In order to realize plug and play, the set top box uses a built-in default account number/password for authentication for the first time; after the address of the IPTV is acquired, communication with a management platform is actively initiated, and the individual account number/password of the single user can be acquired.

And then, after the set top box acquires the personalized account number/password, the set top box needs to actively disconnect and restart, and uses the personalized account number/password to complete the second tunnel and session establishment by going to the BRAS, so that the user authentication is in the full online process.

The scheme provided by the embodiment of the present application is described below by comparing the scheme of manually modifying the IPTV service with the scheme provided by the embodiment of the present application.

Fig. 8a shows a network structure of an OTT TV service, and if a network of the OTT TV service is upgraded and modified into an IPTV by manually going up, the modified network structure of the IPTV service is shown in fig. 8 b. According to the scheme of manual entry-up upgrading and reconstruction, the IPTV set top box is required to be connected to another bridge LAN of the optical modem, so that the separation of the IPTV channel and the broadband channel is realized, and the OTT set top box is upgraded to an IPTV version.

If the network structure shown in fig. 8a is modified by adopting the scheme provided by the embodiment of the application, the modified IPTV service network structure is shown in fig. 8 c. The IPTV STB is the original OTT STB. The scheme provided by the embodiment of the application takes the router in the user home network as a part of the underly layer, so that IPTV service is only related to the on-off property of the underly layer, any home networking can be adapted, and the difficulties of the entry of maintenance personnel and the reconstruction of the home network are avoided. The OTT set top box can be flexibly and remotely accessed into the IPTV network, and the migration and upgrading from the OTT TV service to the IPTV service are realized.
