Are some operators relying entirely on PCRF systems (Policy & Charging Rules Function) as a solution?
JA: I don’t know of any operator who is only relying on PCRF. That would be a bit foolish as there are great things happening in the network to support greater volumes/speeds at lower cost. But what is clear is that growth in demand will outstrip all of these network-only advancements. At CTIA in March, we were told that LTE will provide about a sevenfold increase, but at the same time we heard that last year the demand for bandwidth grew tenfold. This year the expectation is even higher. So PCRF, and more importantly the Charging/Policy ecosystem, is a crucial part of the solution as operators must get the revenue side of the equation right too. VP: In view of this capacity crunch what answers are there for operators caught between falling voice revenues and the dwindling profitability of their broadband data services? JA: Broadband data is clearly where the growth opportunities are going to be. In fact, I experienced a HD (high definition) voice service the other day, and it dawned o
