detailed description

Two tunnels are usually established between the user terminal and the HAAP, one of which is a fixed network tunnel, such as a digital subscriber line (English: Digital Subscriber Line, DSL for short) tunnel, and the other is a wireless network tunnel, such as the Long Term Evolution (English : Long Term Evolution, referred to as: LTE) tunnel. When the bandwidth of the service data is smaller than the bandwidth of the fixed network tunnel, all the service data is transmitted through the fixed network tunnel. And when the bandwidth of the service data is greater than the bandwidth of the fixed network tunnel, the service data is jointly transmitted through the fixed network tunnel and the wireless network tunnel, wherein the wireless network tunnel is used to transmit the service data, Data exceeding the bandwidth of the fixed network tunnel. For example, when the bandwidth of the service data is 100 megabytes (M), the bandwidth of the DSL tunnel is 80M, and the bandwidth of the LTE tunnel is 40M, it can be seen that the bandwidth of the service data is greater than the bandwidth of the DSL tunnel, so the data of the 80M bandwidth in the service data The data that exceeds the bandwidth of the DSL tunnel, that is, the data with the remaining 20M bandwidth, is transmitted through the LTE tunnel, so that the existing network equipment resources are utilized, and the wireless bandwidth is maximized to improve the user bandwidth experience. Improve the competitiveness of operators.

However, the current protection measures for data transmission are only to use the wireless network tunnel for transmission when the fixed network tunnel fails, and use the fixed network tunnel for transmission when the wireless network tunnel fails. There are no protection measures for these two tunnels. This leads to lower reliability of data transmission. For example, when both tunnels fail, all service data cannot be transmitted; Data transmitted over the wireless network tunnel cannot be transmitted.

However, in the embodiment of the present invention, the tunnel establishment method and related equipment are used to protect the fixed network tunnel or the wireless network tunnel, thereby improving the reliability of data transmission.

A preferred manner is to sequentially establish a main fixed network tunnel, a backup fixed network tunnel, a main wireless network tunnel and a backup wireless network tunnel.

It can be known from the above technical solutions that in the embodiment of the present invention, in addition to the first type of primary tunnel and backup tunnel, that is, the first tunnel and the second tunnel, a second type of primary tunnel is also established between the user terminal and the HAAP. and backup tunnels, that is, the third tunnel and the fourth tunnel, wherein the tunnels of the first type and the second type are fixed network tunnels and wireless network tunnels respectively, so the embodiment of the present invention realizes the establishment of two fixed network tunnels and two wireless network tunnels network tunnel, which includes a main fixed network tunnel, a backup fixed network tunnel, a main wireless network tunnel and a backup wireless network tunnel. The concept of GRE tunnel protection group is proposed, which provides reliable protection against tunnel failure and traffic bandwidth switching. Technical solution support.

In the above two embodiments, the method of establishing the primary tunnel and the backup tunnel is introduced, and how to use the primary tunnel and the backup tunnel will be described in detail below. Firstly, the description is made from the perspective of the user terminal.

In the embodiment shown in FIG. 1, the first tunnel and the second tunnel are established, wherein the first tunnel and the second tunnel are tunnels of the same type, for example, both are DSL tunnels or both are LTE tunnel. Since the first tunnel is the primary tunnel and the second tunnel is the backup tunnel, when the first tunnel is normal, service data is transmitted through the first tunnel, and when the first tunnel fails, the The user terminal may transmit the service data transmitted on the first tunnel through the second tunnel.

In the embodiment shown in Fig. 3, the first tunnel, the second tunnel, the third tunnel and the fourth tunnel are established, wherein the first tunnel and the second tunnel are the same type of tunnel, the third tunnel and the fourth tunnel are of the same type of tunnel, and the first tunnel and the third tunnel are of different types of tunnels. For example, both the first tunnel and the second tunnel are DSL tunnels, and both the third tunnel and the fourth tunnel are LTE tunnels.

Therefore, when the first tunnel and the third tunnel are normal, the user terminal transmits data through the first tunnel and the third tunnel. For example, assuming that the first tunnel is the main DSL tunnel, and the third tunnel is the main LTE tunnel, if the bandwidth of the service data is less than or equal to the bandwidth of the main DSL tunnel, the user terminal in the main DSL tunnel If the bandwidth of the service data is greater than the bandwidth of the main DSL tunnel, the user terminal transmits service data on the main DSL tunnel and the main LTE tunnel.

When the first tunnel fails, the user terminal may transmit the service data transmitted on the first tunnel through the second tunnel. When the third tunnel fails, the user terminal may transmit the service data transmitted on the third tunnel through the fourth tunnel. For example, assuming that the first tunnel is the primary DSL tunnel, the second tunnel is the backup DSL tunnel, the third tunnel is the primary LTE tunnel, and the fourth tunnel is the backup LTE tunnel, when the primary DSL tunnel fails , the service data transmitted on the main DSL tunnel is transmitted through the standby DSL tunnel, so as not to affect the LTE service; when the main LTE tunnel fails, the service data transmitted on the main LTE tunnel is transmitted through the standby LTE tunnel Transmission, so as not to affect the DSL business.

Moreover, when the first tunnel recovers from a failure, the user terminal can keep the service data transmitted on the second tunnel to be transmitted on the second tunnel, thereby reasonably reducing the impact of packet loss and the number of switching times. Similarly, when the third tunnel recovers from a fault, the user terminal may keep the service data transmitted on the fourth tunnel to be transmitted on the fourth tunnel. When the first tunnel recovers from a fault, the user terminal may also enable the service data transmitted on the second tunnel to be transmitted through the first tunnel, thereby facilitating management and maintenance. Similarly, when the third tunnel recovers from the failure, the user terminal may also enable the service data transmitted on the fourth tunnel to be transmitted through the third tunnel.

The above describes how the user terminal uses the primary tunnel and the backup tunnel, but in fact, HAAP uses the primary tunnel and the backup tunnel in a similar way, so it will not be repeated here.
