Appl. No.:

8/771475

Inventors:

Ronald B. Bell - Plano TX

International Classification:

H04J 312

US Classification:

370236

Abstract:

A method (100, 700, 800) for detecting and eliminating circular routed messages in a telecommunications network includes the steps of receiving a message, and determining a derived destination point code for the received message (102). The derived destination point code is then compared with an originating point code in the message (108). A circular routed message is detected if the derived destination point code is the same as the originating point code. This comparison may be disabled and instead the routing information for routing the message indicated by the derived destination code may be compared with the originating point code (706). Alternatively, the network identifiers indicated by the derived destination point code and the originating point code are compared (806).

Abstract:

A signal transfer point (14) in a telecommunications network (10) distributes messages to a plurality of service control points (16) as a result of global title translation processing. The signal transfer point (14) assigns a message allocation to each of the service control points (16). The signal transfer point (14) equally distributes messages to the service control points (16) in a sequential manner. The signal transfer point (14) keeps track of the number of messages sent to each service control point (16). When a particular service control point (16) reaches its message allocation, the signal transfer point (14) prevents further messages to be sent to the particular service control point (16). The signal transfer point (14) then continues sequential and equal distribution to the remaining service control points (16) until each service control point (16) reaches its message allocation. The signal transfer point (14) then resets to send a next set of messages to the service control points (16).
