According to Mobily annual report (here), in 2012 "Data traffic on wireless broadband network services grow from 163 to 750 terabyte per day". Probably in order to accommodate this demand to traffic, Mobily has upgraded its core wireless netwrok.
Telecom Lead reports that "Mobily has selected Ericsson to provide Evolved Packet Core networks in the western region of the Kingdom. The Ericsson EPC solution enables Mobily subscribers to have the ability to access and consume four times more data .. As per the agreement, Ericsson will upgrade the EPC network with the Evolved Packet Gateway based on the SSR 8000 family to support LTE and prepare the network for Voice over LTE .. The enhanced capacity of the network will allow Mobily mobile customers to use and consume bandwidth-hungry applications and services while maintaining high quality of experience for all users".
Is Mobily going to use DPI to manage those "bandwidth-hungry applications" ? Two years ago I reported that Mobily is using Bridgewater's (now Amdocs) PCRF with Cisco's SCE DPI devices for its 3G network (here). However, the Ericsson SSR 8000 has its own DPI (see "Ericsson Adds DPI and Wi-Fi to SSR 8000" - here).
Nasser Al Nasser, COO, Mobily, said: “To provide our customers with an unparalleled mobile-broadband experience, we constantly look for ways to efficiently maintain and increase network availability and enhanced Quality of Service (QoS) to support LTE”
