Telefonica: "We are also studying policy service implementation"

Huawei published in its Communicate Magazine (July '12 edition - here) an interview with Cayetano Carbajo (pictured), Telefónica Global Technology Director, about ".. the operator’s service platform and operation center innovations, as well as its All-IP transition process, and how they better suit customers’ changing consumption habits".

Mr. Carbajo said that "Quality of service (QoS) is also very important and the policy enforcement point is key ..To ensure QoS, you have to define the policy enforcement points. Today we have a QoS mechanism at nodes such as the gateway GPRS support node (GGSN) and broadband remote access server (BRAS). We are also studying policy service implementation. For quality of experience (QoE), it is more difficult as we are quite blind to end-to-end QoE, so we are implementing a solution to first monitor and measure QoE. With that information, we can make decisions and policies for enhanced QoE".

"There are lots of things to be modified in the network for managing video traffic. The QoS requirements for video services are different compared with legacy services, and the network needs to be restructured for carrying video traffic. There are many things on which we have to work. The first thing is the distribution of video content in the right way. For video-on-demand (VOD), video over-the top (OTT), and IPTV services, a content delivery network (CDN) is the right approach. For P2P or video communication services, you have to enable the core or control part for an IP multimedia database, so IMS will play a key role there".
