The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. In order to clearly describe the present invention, a brief introduction to the DTV (Digital Tele TV) system will be given. As shown in FIG. 1, the DTV system 1 includes a BMS2, an STB3, and a VOD (Video on Demand) platform 4, and the STB can acquire and display digital television services for users from the V0D platform under the management scheduling of the BMS. Among them, some STBs can use the IP network service network and the HFC network service network to carry out IP network and HFC network services respectively. At this time, the BMS can select the different network (IP or HFC) to provide services for the user by using the user network capability information entered when the user opens an account or the network access capability information sent by the STB when booting, and combining the service resources and the pre-configured policies. . Embodiment 1 As shown in FIG. 2, the network switching method provided by the embodiment of the present invention includes the following steps:

Sl l, the BMS receives the network service capability information of the service network currently used by the STB sent by the STB; 512. The BMS determines, according to the received network service capability information, whether a network service capability of the service network currently used by the STB supports the current service of the STB.

513. If the network service capability of the service network currently used by the STB does not support the current service of the STB, the BMS instructs the STB to perform handover of the service network. In S11, the BMS may receive the network service capability information of the service network of the STB by sending a query instruction to the STB and receiving the response message of the STB. Preferably, the BMS may be at a predetermined time, such as half an hour. The query command is sent to the STB to periodically learn about the STB's network service capabilities. Or the BMS can directly receive the network service capability information that the STB actively sends. Optionally, the STB has two service networks, namely an HFC network and an IP network, and the service network currently used by the STB may be any one of the two service networks. Correspondingly, the network service capability information of the service network currently used by the STB includes network service capability information of the IP network and network service capability information of the HFC network. The network service capability information of the IP network may include a data transmission rate fluctuation range of the IP network or a current available bandwidth of the IP network. The network service capability information of the HFC network may include network status information of the HFC network, where the status information can indicate the current status of the STB. Whether the service network used is in a fault state. In S12, according to different contents included in the network service capability information, the manner in which the BMS determines whether the network service capability of the service network currently used by the STB supports the current service of the STB is also different. Specifically, when the service network currently used by the STB is an IP network, and the network service capability information of the IP network can be a data transmission rate fluctuation range of the IP network, the BMS can learn the fluctuation range of the data transmission rate according to the fluctuation range of the data transmission rate. And determining whether the network service capability of the IP network currently used by the STB supports the STB by determining whether the data transmission rate fluctuation range of the IP network covers the code rate of the transmission content and whether the fluctuation amplitude exceeds a specified fluctuation range. Current business. When the data transmission rate fluctuation range covers the code rate of the transmission content and the fluctuation amplitude exceeds the specified fluctuation amplitude range, it may be determined that the network service capability of the IP network currently used by the STB does not support the current service of the STB. Otherwise, the BMS may determine that the network service capability of the IP network currently used by the STB supports the current service of the STB, and does not need to switch the service network of the STB. For example, in one embodiment of the present invention, an STB is using an IP network for video signal transmission services, and the code rate of the transmitted content is 1 M per second, and the data transmission rate fluctuates from 2 M per second to 3 M per second, assuming that The fluctuation range of 0. 4M per second, the BMS can know the fluctuation range of the data transmission rate from the fluctuation range of the data transmission rate, although the fluctuation rate of the data transmission rate reaches (3-2) = 1M per second, exceeding 0 4M The specified range of fluctuations per second, but since the data transmission rate fluctuates from 2M to 3M, the code rate of 1M per second is not covered. Even if the fluctuation is larger, it will not affect the current video signal transmission service. Therefore, the BMS can determine that the network service capability of the IP network supports the current service. However, if the data propagation rate fluctuates from 0. 6M per second to 1. 2M per second, that is, the fluctuation range of the data propagation rate covers the code rate of the transmission content of 1M per second, and the fluctuation range (1.2-0) 6) =0. 6M per second exceeds the specified fluctuation range 0. 4M per second, at this time the buffer in the STB is not enough to make up for the difference between the data transmission rate and the transmission content rate, which will affect the user's appreciation effect. Therefore, the BMS can determine that the network service capability of the IP network does not support the current service at this time. Specifically, when the service network currently used by the STB is an IP network, and the network service capability information of the IP network can also be the currently available bandwidth of the IP network, the BMS can determine whether the current available bandwidth of the IP network is greater than the current transmission content. The code rate is used to determine whether the network service capability of the IP network currently used by the STB supports the current service of the STB. When the current available bandwidth of the IP network is less than or equal to the code rate of the currently transmitted content, it may be determined that the network service capability of the IP network currently used by the STB does not support the current service of the STB. Otherwise, the BMS may determine that the network service capability of the IP network currently used by the STB supports the current service of the STB, and does not need to switch the service network of the STB. For example, in another embodiment of the present invention, the available bandwidth of the current IP network is 400 KB per second, and the code rate of the transmitted content of one service is 450 KB, that is, the available bandwidth is smaller than the code rate of the transmitted content, so the BMS determines the IP network. The network service capability under the service network does not support the current service; and if the code rate of the transmission content of another service is 200 KB, that is, the available bandwidth of the IP network is greater than the code rate of the transmitted content, the BMS can determine the network service capability of the IP network to support the current business. It should be noted that if the current STB is using the IP network to provide services, the currently available bandwidth needs to include the portion of the current data stream that is already occupied. Of course, in other embodiments of the present invention, the network service capability of the IP network may also be other parameters, as long as the current service capability of the local network can be indicated, which is not limited by the present invention. Specifically, when the service network currently used by the STB is an HFC network, the network service capability information received by the BMS may be network status information of the HFC network, and the status information is used to indicate whether the service network currently used by the STB is in a fault state. Determining, according to the network status information of the HFC network, that the network status of the HFC network is a fault, the BMS determines that the network service capability of the HFC network does not support the current service of the STB according to the network status information of the HFC network, otherwise determining The network service capability of the HFC network supports the current service of the STB. In step S13, the BMS may indicate that the STB is switched by the IP network service network to the HFC network service network, or the STB is switched by the HFC network service network to the IP network service network. When the currently used service network is an IP network, the BMS instructs the STB to switch from the IP network service network to the HFC network service. The service network specifically includes: Step 1: The BMS selects an IPQAM (IP Quadrature Amplifier Modular Modulation) resource, where the IPQAM resource includes an IPQAM IP address, a port number, a transceiving stream point, and a service identifier ( Service ID); Step 2: The BMS sends, to the STB, handover indication information that is switched to the HFC network, where the handover indication information includes the transceiver flow frequency point. Step 3: The BMS notifies the V0D according to the IP address and the port number. The platform switches the traffic destination target, so that the STB receives the data flow corresponding to the service identifier by using the transceiver flow frequency point in the HFC network. When the currently used service network is an HFC network, the BMS indicates that the STB is switched from the HFC network service network to the IP network service network, and the method includes: Step 1: The BMS sends the handover indication information to the STB to switch to the IP network; Step 2: BMS Receiving the IP address and the port number information returned by the STB. Step 3: The BMS notifies the V0D platform to switch the traffic destination according to the IP address and the port number information, so that the STB receives the IP network. data flow. It should be noted that, in this embodiment, the BMS only determines whether the network service capability of the service network currently used by the STB supports the current service of the STB, and further determines whether it is the STB handover service network, but the present invention is not limited thereto. The network switching method provided by the embodiment of the present invention enables the BMS to know the network service capability of the service network currently used by the STB in time, determine whether the current service capability supports the current service, and instruct the STB that the network service capability does not support the service network of the current service. Timely switching to the network service capability can support the service network of the current service, ensuring the transmission quality and continuity of the current service, thereby automatically avoiding the dysfunctional network for the user without disturbing the user's use, and selecting the network service capability. A good network, thus effectively improving the user experience.

Embodiment 2 The embodiment of the present invention further provides a network switching method. As shown in FIG. 3, the method includes the following steps:

S1001: The BMS receives the network service capability information sent by the STB, where the network service capability information includes network service capability information of the service network currently used by the STB, and a network service of the service network that is used by the STB. Service capability information;

It should be noted that, optionally, the STB may send network service capability information of the service network currently used and used by the STB simultaneously or separately, that is, in this step, the BMS may receive the currently used sum simultaneously or separately. Network service capability information of the service network that is alternatively used;

S1002: The BMS determines, according to the received network service capability information of the service network that the STB currently uses, whether the network service capability of the service network currently used by the STB supports the current service of the STB.

S1003, if the network service capability of the service network currently used by the STB does not support the current service of the STB, the BMS determines the STB according to the network service capability information of the service network that is used by the STB candidate to be used. Whether the network service capability of the service network that is alternatively used supports the current service of the STB; S1004, if the network service capability of the service network used by the STB alternative supports the current service of the STB, the BMS indicates the service of the STB The network is switched by the currently used service network to the alternately used service network. In S1001, the BMS may receive the network service capability information of the service network of the STB by sending a query instruction to the STB and receiving the response message of the STB. Preferably, the BMS may be at a predetermined time, for example, half an hour. The query command is sent to the STB to periodically learn about the STB's network service capabilities. Or the BMS can directly receive the network service capability information that the STB actively sends. Among them, STB has two service networks, namely the service network of the HFC network and the service network of the IP network. The service network currently used by the STB can be any one of the two service networks, and the service network used by the STB is optional. Then it is the remaining one. Correspondingly, the network service capability information also includes the network service capability information of the IP network and the network service capability information of the HFC network. The network service capability information of the IP network includes a data transmission rate fluctuation range of the IP network or a current available bandwidth of the IP network. The network service capability information of the HFC network includes network state information of the HFC network, and the status information is used to indicate that the STB is currently used. Whether the service network is in a fault state. Specifically, in step S1001, when the STB currently uses the HFC network, the network service capability information received by the BMS may include network service capability information of an alternative use network of the STB, such as an IP network, in addition to the network state information of the HFC network. Such as the current available bandwidth of the IP network. Similarly, when the STB currently uses the IP network, the received network service capability information may include network status information of the STB's alternative use network, such as the HFC network, in addition to the network service capability information of the IP network. Specifically, in step S1002, the BMS is configured to determine, according to the received network service capability information, the Whether the network service capability of the service network currently used by the STB supports the current service of the STB. For the specific method of this step, refer to the related description in the first embodiment, and details are not described herein again. For example, in an embodiment of the present invention, the service network currently used by the STB is an HFC network, and the service network used alternatively is an IP network, and the BMS first determines according to the network service capability information received in step S1001. Whether the network service capability of the HFC network supports the STB current service, if it supports, no network switching is required. In step S1 003, if the network service capability of the service network currently used by the STB does not support the current service of the STB, the BMS determines, according to the network service capability information, the service network of the STB candidate to use. Whether the network service capability supports the current service of the STB. It should be noted that whether the network service capability of the service network used by the STB supports the current service of the STB, that is, whether the network service capability of the IP network or the HFC network supports the current service of the STB. The method for determining is the same as the method for determining the service network currently used by the STB by the IP network or the HFC network, and details are not described herein again. In step S1004, if the network service capability of the alternately used service network supports the current service of the STB, the service network of the STB may be instructed to be switched by the currently used service network to the candidate use. Service network. If the network service capability of the service network that is used by the candidate does not support the current service of the STB, the BMS may further improve the user experience by using the STB to give the user a friendly prompt with no available network. In this way, regardless of the service network currently used by the STB, the BMS can obtain the network service capability of the HFC network and the network service capability of the IP network by receiving the network service capability information of the STB, so as to effectively switch the service network of the STB, thereby ensuring that the BMS service network is effectively switched. The quality of service further enhances the user experience. The network switching method provided in this embodiment enables the BMS to determine the current use and the alternative of the STB by receiving the network service capability information of the service network currently used by the STB and the network service capability information of the service network used by the STB. Whether the network service capability of the service network used supports the current service, and when the network service capability of the service network currently used by the STB does not support the current service, the STB is switched to the service network that supports the current service in time, thereby avoiding User services are interrupted, thus improving the user experience.

Correspondingly, the embodiment of the present invention further provides a network switching method. As shown in FIG. 4, the method includes the following steps: S21: The STB acquires network service capability information of a service network that is currently used by the STB. 522. The STB sends the network service capability information to the BMS.

523. When the BMS determines that the network service capability of the service network currently used by the STB does not support the current service, the STB receives the handover indication information of the service network sent by the BMS.

524. The STB performs handover of the service network according to the handover indication information of the service network. Among them, the STB has two service networks, which are the service network of the HFC network and the service network of the IP network. The service network currently used by the STB may be any one of the two service networks. Correspondingly, the network service capability information of the service network currently used by the STB includes network service capability information of the IP network and network service capability information of the HFC network. The network service capability information of the IP network includes a data transmission rate fluctuation range of the IP network or a current available bandwidth of the IP network. The network service capability information of the HFC network includes network state information of the HFC network, and the status information is used to indicate that the STB is currently used. Whether the service network is in a fault state. Specifically, in step S21, the STB can obtain the network service capability information of the HFC network by detecting the driving interface of the HFC network, or obtain the service capability information of the IP network by querying the data flow information of the IP network. In other embodiments of the present invention, the STB may also obtain network service capability information of the service network of the STB by other means, which is not limited by the present invention. In step S22, the STB may send the network service capability information to the BMS according to the query instruction of the BMS. Optionally, the STB may also send network service capability information to the BMS at a predetermined time, such as half an hour. Optionally, the STB may also send the network service capability information to the BMS when the network service capability of the serving network is abnormal. For example, the STB may send network service capability information to the BMS when the HFC network fails or the IP network data transmission rate fluctuates greatly, so that the BMS can determine in time whether the network service capability of the service network currently used by the STB supports the current service. . In step S23, the handover indication information that is received by the STB indicating that the service network is currently used may indicate that the service network currently used by the STB is switched from the IP network to the HFC network, and may also indicate that the service network currently used by the STB is used by the HFC. The network switches to the IP network. Specifically, when the STB currently uses the IP network, and the BMS determines that the network service capability of the IP network cannot support the current service, the STB may receive the handover indication information that is sent by the BMS to the HFC network service network, where the handover indication information is It includes the specified transceiver stream frequency point. When the STB currently uses the HFC network, and the BMS determines that the network service capability of the HFC network cannot support the current service, the STB may receive the handover indication information that is sent by the BMS to the IP network service network. Correspondingly, in step S24, the STB performs handover of the service network according to the handover indication information of the service network, and specifically includes switching from the IP network service network to the HFC network service network or from the HFC network service network to the IP network service network. . When the handover indication information received by the STB indicates that the service network currently used by the STB is switched from the IP network to the HFC network, in step S24, the STB switches to the HFC network according to the handover indication information, and The data stream is received in the HFC network using the transceiving stream frequency point. When the handover indication information received by the STB indicates that the service network currently used by the STB is handed over to the IP network by the HFC network in step S23, the STB will switch to the IP network service network according to the handover indication information in step S24. Specifically, the STB listens to the user data packet protocol UDP (User Datagram Protoco l) and collects the port

The BMS sends the IP address and the inbound port number information, so that the BMS notifies the V0D platform to switch the traffic destination according to the IP address and the port number information; thereby completing the handover from the HFC network to the IP network, and receiving data on the IP network. flow. It should be noted that, in this embodiment, the STB only sends the network service capability information of the currently used service network to the BMS, so that the BMS determines whether it is the STB handover service network, but the present invention is not limited thereto. According to the network switching method provided by the embodiment of the present invention, the STB can obtain the network service capability information of the service network currently used by the STB, and send the network service capability information to the BMS, and then the handover indication information of the service network of the BMS, and the network is timely The service capability does not support the current service. The service network switches to the network service capability to support the service network of the current service, ensuring the transmission quality and continuity of the current service, thereby automatically avoiding dysfunction for the user without disturbing the user's use. The network, while choosing a network with good service capabilities, effectively enhances the user experience.

Embodiment 4 The embodiment of the present invention further provides a network switching method. As shown in FIG. 5, the method includes the following steps:

52001, the STB acquires network service capability information of the service network of the service network, where the network service capability information includes network service capability information of the service network currently used by the STB and network service capability information of the service network that is used by the STB;

52002, the STB sends, to the BMS, network service capability information of the service network currently used by the STB and network service capability information of the service network that is used by the STB; 52003, when the BMS determines that the network service capability of the service network currently used by the STB does not support the current service, and the network service capability of the service network used by the STB candidate supports the current service of the STB, the STB receiving station Decoding indication information of the service network sent by the BMS;

52004. The STB switches, according to the handover indication information of the service network, the service network that is currently used to the service network that is used by the candidate. It should be noted that, in step S2001, the STB may acquire network service capability information of the service network currently used by the STB and network service capability information of the service network that is used by the STB simultaneously or separately, in step S2002. The network service capability information of the service network that is currently used by the STB and the network service capability information of the service network that is used by the STB may be sent simultaneously or separately, which is not limited by the present invention. The STB has two service networks, namely a service network of the HFC network and a service network of the IP network, and the service network currently used by the STB may be any one of the two service networks. Correspondingly, the network service capability information of the service network currently used by the STB includes the network service capability information of the IP network and the network service capability information of the HFC network. The network service capability information of the IP network may include a data transmission rate fluctuation range of the IP network or a current available bandwidth of the IP network. The network service capability information of the HFC network may include network state information of the HFC network, where the status information is used to indicate the STB. Whether the currently used service network is in a fault state. Specifically, in step S2001, the STB can obtain network service capability information of the HFC network and the IP network. Specifically, the STB can obtain the network service capability information of the HFC network by detecting the driving interface of the HFC network; and obtain the service capability information of the IP network by querying the data flow information of the IP network. In other embodiments of the present invention, the STB can also obtain the network service capability information of the service network of the STB through other means, which is not limited by the present invention. For example, when the STB currently uses the HFC network, the STB can obtain the network status information of the HFC network.

Network service capability information of the IP network. Similarly, when the STB currently uses the IP network, the STB can obtain the network service capability information of the HFC network in addition to the network service capability information of the IP network. The present invention does not limit this. In step 2002, the STB may send the network service capability information to the BMS according to a query instruction of the BMS. Optionally, the STB may also send the network service capability information to the BMS when the network service capability of the serving network is abnormal. In this way, regardless of the service network currently used by the STB, the STB can send the network service capability information of the service network in use and the network service capability information of the service network to be used to the BMS, so that the BMS can determine whether the STB needs The service network is switched, so that the STB can effectively switch the service network according to the indication of the BMS, thereby ensuring the quality of the service and further improving the user experience. Further, in another embodiment of the present invention, when the service capability of the service network currently used by the STB does not support the current service of the STB, and the network service capability of the service network that is alternatively used does not support the current service of the STB. At the same time, the STB can receive the prompt of the BMS, giving the user a friendly prompt with no available network, further improving the user experience. It should be noted that, optionally, the STB provided by the embodiment of the present invention may also send its network access capability information to the BMS. The network access capability refers to the ability of the STB to access the IP network or the HFC network, including whether the STB device supports the access of the IP network or the HFC network, and whether the location of the STB is set to an IP network or an HFC network. That is, in an embodiment of the present invention, the STB can timely update its static network information such as network support, local network deployment, and the like, and whether the local network fails or whether the data transmission conditions can support the current service. Sent to the STB. Optionally, when the STB is powered on, simultaneously sending its network service capability information and network access capability information, so that the STB can use the most suitable service network.
