  • Depending on available time, slides 7, 9, 10, 12 and 13 can be omitted.
  • Where is revenue growth going to come from? With both voice AND data revenues declining or static, value needs to be obtained from somewhere. This could mean that differential pricing for data becomes common, but it can also drive OPEX savings by ensuring that existing resources are used more efficiently.
  • Mobile video will increase many times faster than revenue. Not all of this is real time, but there will also be growth in real time mobile video services. How can these be delivered successfully, given the overall growth of data / video traffic?
  • Although this comes from the UK, the position is likely to be similar in most countries that have widespread 3G / HSPX adoption. When LTE is considered, the situation is likely to worsen.
  • Competitive advantages? As per the AT&T statement.
  • There appears to be a willingness to pay for differentiated / tiered levels by certain parts of the customer base. Vodafone, AT&T already claim to have customers on this. Future-proofing is another factor (otherwise just continually throwing more more bandwidth instead of making the existing structure more efficient). Controlling it at source. Scalable option across existing customer base.
  • There is apparently value in its predictability – especially in terms of network planning. It is compatible with any existing network. It controls at source. Does not require another “box” in the network.
  • Simple to integrate….GoS does not require a new network element, it can be integrated into existing solutions and network architectures.
  • The traffic / policy control aspect delivers prioritisation which can include “throttling” (potentially important for a number of potential customers)
  • The ‘automatic’ part is referencing VoiceQoS: we haven’t got a clear policy as to whether we regard this as part of ‘GoS’ or not.
  • This should be entitled ‘What GoS Does’ – it is in no sense an explanation of how it works!!
  • Not sure what the icons are doing here!Don’t think the title “Use Cases” is correct as the following Use Case slides are applications. This slide is more about physical deployment options?
  • I would suggest putting the title: “Use Cases: UC, Collaboration & VoIP” and bring all the sub-bullet points in one space
  • I would suggest putting the title: “Use Cases: Video Services” and bring all the sub-bullet points in one space
  • As per previous slides
  • At this point we could make a reference to our GoS Framework solution
