Embodiment 1

[0043] Such as image 3 As shown, it is a flow chart of the route reselection determination method provided in Embodiment 1 of the present invention, including the following steps:

[0044] S301: The first DRA node in the first operator's network forwards the request message sent by the second node to the third node.

[0045] The request message here is the Diameter signaling request message.

[0046] S302: After the first DRA node receives the routing error response message sent by the third node, based on the source host identifier carried in the routing error response message, determine the type of the source host sending the routing error response message; the source host type Nodes in other operator networks, non-DRA nodes in the first operator network, and DRA nodes in the first operator network, where the DRA node in the first operator network is paired with the first DRA node A DRA node, or a DRA node not paired with the first DRA node.

[0047] S303: Based on the d...

Embodiment 2

[0059] As shown in Figure 4(a), it is a flow chart of the routing reselection determination method provided by Embodiment 2 of the present invention, and Figure 4(b) is a schematic diagram of routing corresponding thereto; when the path is normal, the first operator network The source signaling node of DRA1a sends a Diameter request message, which is sequentially forwarded by DRA2a, DRA3a, DRA4a... and other nodes to reach the destination signaling node of the second operator network, that is, the routing path is source signaling node -> DRA1a ->DRA2a->DRA3a->DRA4a->... (a node in the second operator's network) -> the destination signaling node.

[0060] Specifically include the following steps:

[0061] S401: The source signaling node of the first operator's network sends a Diameter request message from DRA1a, passes through DRA2a and DRA3a, and then reaches DRA4a.

[0062] S402: After the DRA4a forwards the Diameter request message, it receives a routing error response mess...

Embodiment 3

[0070] As shown in Figure 5(a), it is a flow chart of the route reselection determination method provided by Embodiment 3 of the present invention, and Figure 5(b) is a schematic diagram of the corresponding routing; when the path is normal, the first operator network The source signaling node in DRA1a sends a Diameter request message, which is sequentially forwarded by DRA2a, DRA3a, and DRA4a, and then reaches the destination signaling node of the first operator network, that is, the routing path is source signaling node->DRA1a- >DRA2a->DRA3a->DRA4a->destination signaling node.

[0071] Specifically include the following steps:

[0072] S501: The source signaling node of the first operator's network sends a Diameter request message from DRA1a, passes through DRA2a and DRA3a, and then reaches DRA4a.

[0073] S502: After the DRA4a forwards the Diameter request message, it receives a routing error response message.

[0074] S503: DRA4a determines, based on the source host iden...

Abstract

The method relates to the communication technology field and especially relates to a routing reselection determination method based on a diameter protocol and an apparatus thereof. The method comprises the following steps of forwarding a request message sent by a second node to a third node by a first DRA node; after a routing error response message is received, based on a source host identification carried by the message, determining a source host type which sends the routing error response message; based on the source host type, determining whether routing reselection needs to be initiated; after the routing reselection is determined not to be initiated, returning a permanent error response message to the second node; after the routing reselection is determined to be initiated, determining whether there are other routings used for transmitting the request message, if there is no other routings and if the source host type is a DRA node which forms a pair with the first DRA node, returning the permanent error response message to the second node, and if the source host type is a DRA node which does not form a pair with the first DRA node, returning the routing error response message to the second node.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for judging route reselection. Background technique [0002] The Diameter protocol is a typical communication protocol between network elements of the core network in the Internet Protocol (Internet Protocol, IP) era, and the network elements of the core network communicate through a Diameter signaling interface. For the convenience of maintenance and management, a routing agent (Diameter Routing Agent, DRA) node is used to forward Diameter signaling messages between network elements of the core network (that is, Diameter signaling nodes). In order to ensure safety and reliability, DRA nodes are generally deployed in pairs, and a pair of DRA nodes are connected through a C link. They serve as backups for each other and share the load together. When the Diameter signaling network adopts a multi-level structure, multiple DRA nodes may be used for...
