Embodiment Construction

[0033] Communication networks are not guaranteed to be reliable. The 3GPP standards basically provide no guidance on how to deal with communication failures in EPC. For example, a session termination request sent to a policy and charging rules node may not be received. In this case, the session and any bound sessions may not be terminated at each network element, which creates orphaned sessions. A session may also be inactive at the network element that initiated the session, but active at other network elements. These orphaned and inactive sessions continue to consume system resources such as guaranteed bandwidth, system memory, and processing time.

[0034] As mentioned earlier, it is desirable to provide the ability to remove orphaned or inactive sessions. In particular, it is desirable to detect and terminate orphaned and inactive S9 sessions without interfering with the operation of other network elements.

[0035] Referring now to the drawings, there are disclosed br...

Abstract

Various exemplary embodiments relate to a method and related network node including one or more of the following: determining by the network device that an S9 session should be audited; determining that the S9 session is a suspect session; transmitting an S9 message to a partner device, wherein the S9 message includes an innocuous instruction; receiving, at the network device, a response message from the partner device; determining, based on the response message, whether the suspect session is orphaned; and if the suspect session is orphaned, removing an S9 session record associated with the suspect session.

Description

[0001] related application [0002] This application is a continuation-in-part of previously filed Application No. 12 / 825,654, filed June 29, 2010. [0003] This application cross-references throughout its entirety the following co-pending application, which is hereby incorporated by reference in its entirety: Application Serial No. [Pending], Attorney Docket No. ALC3760, "Integrated Roaming and Non-Roaming Message Handling," Ma et al.; and Application Serial No. [pending], Proxy Volume ALC3767, "A PCRN Session Architecture for Roaming," Mann et al. technical field [0004] In general terms, various exemplary embodiments disclosed herein relate to telecommunications networks. Background technique [0005] Due to the growing demand for various types of applications within mobile telecommunications networks, service providers must constantly update their systems to reliably provide this expanded functionality. Once a system designed simply for voice communications has become...
