This is Part II of Peter Nas’ blog post on local break out technology
Peter Nas serves as Senior Solution Architect at F5 Networks and draws from more than 20 years of telecom experience to advise operators how to leverage Diameter signaling solutions to enable the optimal LTE experience. Peter joined F5 with the company’s acquisition of Traffix where he was responsible for global business development. Prior to joining Traffix, he worked at Tekelec focusing on market development for Diameter and SIP routing. In his days before Tekelec, he served as Core Network Engineering Manager at a prominent mobile operator in the Netherlands.
In my last blog post, I began looking at the slow progress for the deployment of LBO (local breakout) technology that will reduce mobile roaming revenues. In this post, I will suggest various ways to leverage LBO to offset the reduction in roaming revenues.
One interesting aspect of LBO is that the signaling for two additional Diameter interfaces, S9 for policy and Gy for charging, could be exchanged between visited and home networks, and if so, this will be done via an IPX network as per GSMA guidelines (IR.88). There are different views on whether or not using the S9 interface to exchange policy information between the visited PCRF and home PCRF, will be massively used once LBO is offered, but let’s assume it will be used. In this case, an IPX carrier can offer various services around Diameter interworking, security and perhaps also screening, overload control, prioritization and potentially adapting policy rules and more.
