Abstract
The present invention presents a flexible method for source-based message routing in a network node, particularly also suitable for flexible load distribution of the traffic via a number of link sets terminating directly at an adjacent first network element. The method uses data structures which are often already available in existing systems or are simple to set up, of providing a number of link sets between two signaling points. A two-stage routing process is initiated based on the setting up of a message node, which supports a number of logical networks or signaling point codes. In the first stage a logical network is selected, in which the message is to be routed further. In the second stage the message is routed in the selected network.
Claims16
A method for routing messages in a node of a communication network, where the node, a first network element and additional network elements are components of a first logical network, and at least the node is a component of at least one second logical network, comprising:
- connecting the node via at least one first connection group in the first logical network and via at least one second connection group to the first network element;
- connecting the node via at least one additional connection group to the additional network elements;
- and
- selecting, for transmission of the messages from the additional network elements to the first network element, the first connection group or the second connection group, based on source identification of the additional network element sending the message.
A method for routing messages in a node of a communication network, comprising:
- transferring, via the node, the message between a first network element and network elements;
- connecting the node via one first connection group and via at least one second connection group to the first network element;
- connecting the node via at least one additional connection group to the additional network elements;
- providing at least two communication addresses for communication between the node and the first network element in the node, with each communication address being associated with one of the connection groups between the node and the first network element;
- and
- selecting, for transmission of the messages from the additional network elements to the first network element, the first connection group with an associated first communication address or the second connection group with an associated second communication address, based on source identification of the additional network element sending the message.
A signaling transfer point of an SS7 network, comprising:
- a first unit for sending and receiving messages from a first signaling point via a first link set and at least one second link set;
- a second unit for sending and receiving messages from additional signaling points via additional link sets;
- and
- a third unit for routing messages, which are configured to route messages based on characteristics of the signaling point sending the message to the first signaling point via one link set from among the available link sets.
