EXPECTATIONS

Meeting Consumer expectations for a particular application is key.

Consumer doesn’t want to care about which “air interface” to use.

Consumer wants us to connect them to their information. Period.

CHALLENGES

Pricing and performance difference between different options.

Make transitions between options or “pathways” seamless.

Make the network adapt to the user, rather than the user adapt to the network.

Configure RAN to handle short packets with no retransmission.

Use SDN techniques to provision a low latency core solution for these connections.

Examine to see if there are any small cells nearby that are switched off and turn them on.

Seek other air interfaces that may have better connectivity.

Provision low latency core network solutions to configure multi-site coordination and interference mitigation techniques. (e.g. CoMP)

FOR CONSUMERS THAT HAVE POOR CONNECTION CONDITIONS:

Configure RAN to support broadcast or unicast based upon traffic request.

Enable CDN systems in the network to support broadcast traffic.

Establish priority in the RAN scheduler to support traffic from the consumer application seeking priority.

Configure the core network to support prioritized traffic from this particular consumer application.

Priority status can be obtained from both the consumer or the end server allowing for generation of priority based revenue.

CONTEXT: IS APPLICATION IN FOREGROUND OR BACKGROUND?

IF FOREGROUND THEN PRIORITIZE HIGHER.

BELL LABS RESEARCH CONTEXT AWARE RESOURCE ALLOCATION [CARA]

60% MORE SMARTPHONES SUPPORTED THAN CLASSIC LTE SCHEDULERS

NEW 5G AIR INTERFACE Support for short information packets – (M2M)

Continued improvement in sensitivity to extend range.

Improvements to increase both consumer battery life and energy consumption.

High frequency / millimeter-wave access technologies.

MOVE TO CLOUD Move of most control/authentication functions to the Cloud.

Fully embrace use of SDN to provision optimum network to support traffic type.

Use of network function virtualization to provide dynamic provisioning and adaptation of the core support for different traffic types and user needs.

COMMUNICATIONS OPTIMIZATIONS Full integration of multiple technologies (WiFi, Bluetooth, WCDMA, LTE, 5G) to provide a single communications solution.

Dynamic (<1s or shorter) pathway response to maintain a high consumer quality and experience.
