1. A method for network fault management in a UMTS radio access network, comprising the steps of:
- initiating by a subscriber a session request to a network via a Session Initiation Protocol (SIP),;
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.

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).

9. A method for utilizing network cause codes in a UMTS radio access network, comprising the steps of:
-
sending a packet data protocol (PDP) context activation request via a Session Initiation Protocol (SIP) 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 detennining is unsuccessful, sending network cause codes to a network manager. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for network fault management in a UMTS radio access network, 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 via a Session Initiation Protocol (SIP) 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. - View Dependent Claims (16, 17, 18)
