Abstract
A mobile subscriber (20) initiates a request for packet data services (100). As the request is processed from network node (40) to network node (50), the transmission is checked for errors (104). For successive failures, exceeding a threshold (108), an alarm condition along with a cause code corresponding to the particular network node is sent to a network system manager (114).
Claims19
A method for network fault management comprising the steps of:
- initiating by a subscriber a session request to a network;
- determining by a first network node whether an error occurred in transmission of the session request to a second network node;
- determining whether an error count exceeded a predetermined threshold;
- and
- if the error count exceeded the predetermined threshold, sending cause codes to a network manager.
A method for utilizing network cause codes comprising the steps of:
- sending a packet data protocol (PDP) context activation request from a first network node to a second network node;
- determining by the second network node whether the PDP context activation request was successfully transmitted from the first network node;
- and
- if the step of determining is unsuccessful, sending network cause codes to a network manager.
A method for network fault management comprising the steps of assigning a unique cause code to each network node of a plurality of network nodes;
- sending a packet data protocol (PDP) context activation request from a first network node to a second network node;
- determining by the second network node whether the PDP context activation request was successfully transmitted from the first network node;
- and
- if the step of determining is unsuccessful, sending network cause codes to a network manager.
