Problems solved by technology

Maintenance risks include failure to restore user business for a long time due to untimely response processing; manual update workload is heavy; error-prone and other risks
Correspondingly, after the disaster-stricken GGSN recovers, some users will be interrupted again when the path is switched back.

Embodiment Construction

[0026] The implementation principle of a service transmission scheme proposed by the embodiment of the present invention is: when a user transmits a service through a GGSN, the GGSN generates a dynamic route for the user, and publishes the user dynamic route to the service provider, and the service provider learns and stores the dynamic route. The user is routed to its own routing table, so that the user's uplink and downlink data packets can be accurately sent to the GGSN, and the automatic routing switching is completed.

[0027] The implementation principle of another service transmission scheme proposed by the embodiment of the present invention is: knowing the exact range of the IP address of the user, the GGSN issues to the service provider the policy information containing the GGSN selected by the service provider and the network information containing the GGSN information. Segment routing, the service provider selects the network segment route according to the policy in...

Abstract

The invention discloses a service transmission method, which comprises when a user account is activated, issuing the routing information of the user to a service provider, wherein the routing information includes issuer information; and transmitting the downlink service data of the user, wherein the downlink service data is issued based on the issuer information involved in the routing information. The invention also provides another transmission method, which comprises issuing the network segment routing to the service provider, wherein the network segment routing includes the information of strategies selected by the provider for the network segment and issuer information; and transmitting the downlink service data of the user, wherein the downlink service data is issued by the service provider based on the strategy information involved in each network segment and the issuer information involved in the network segment selected according to the a predetermined criteria. Correspondingly, the invention further provides a service transmission device. The invention can ensure automatic switching of the downlink data when transmitting service through the reserved gateway GPRS support node (GGSN).

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a service transmission method and device thereof. Background technique [0002] General Packet Radio Service (GPRS, General Packet Radio Service) Gateway Support Node (GGSN, Gateway GPRS Support Node) is a service node in a packet switched (PS, PS PacketSwitched) network, which is highly concentrated on the current network, and its capacity It is the convergence point of the wireless network and the Internet Protocol (IP, Internet Protocol) network. In order to provide users with high-quality and stable services and reduce losses and service interruptions caused by natural disasters, GGSN proposes a network disaster recovery networking solution based on the GGSN resource pool (GGSN POOL). [0003] The GGSN POOL disaster recovery process is actually a replacement process between GGSNs. As shown in Figure 1, there are multiple independent GGSNs in a GGSN POOL. When ...
