Aggregated M2M
The Challenge
M2M communications can generate significant volumes of data traffic from multiple end-point devices and applications. This traffic is expected to grow dramatically in the coming years. Much of this data is non-critical and not real-time, but, among this, there is also data that does have real-time requirements. What's more, there can be multiple sources of M2M data from within the same location, each with different network requirements and demands. Network operators need to be able to aggregate M2M traffic and prioritise that which is real-time, while ensuring collection of non-real time data.
For example, a vehicle may contain several sources of data – ranging from non-critical telemetry and pay-as-you-go insurance information to critical data such as health-monitors, real-time video being viewed by passengers, telephone calls and so on. As the vehicle travels, it may pass through multiple cell locations or enter WiFi access points while stationary. Similarly, a public transport hotspot solution may need to optimise multiple sources of data while in motion.
This data needs to be prioritised and delivered successfully. Operators may seek to deliver real-time policies for the different applications that are running. The problem is compounded in areas of variable mobile coverage. Real-time M2M data from mobile sources must also be secured and protected against contention with other data streams, particularly when there are constraints on bandwidth or variable transmission quality.
The Solution
The solution is to deploy M2M gateways in vehicles or other locations that aggregate M2M traffic, together with the GoS Agent real-time policy enforcement agent on the gateway. With GoS Agent acting as a PCEF on the M2M gateway, enabling the prioritisation of traffic before it is transmitted to the network, operators can ensure that multiple sources of M2M data are accorded the correct priority and deliver dynamic policy control to meet different conditions and requirements.
The GoS Agent can also monitor cellular and WiFi network availability, enabling the 3GPP ANDSF to select the most appropriate connection.
With GoS Manager installed in the network, each in-service gateway can be managed individually to ensure consistent, reliable transmission of real-time M2M data streams.
The Benefits
Enhancing M2M gateways with GoS Agent and deploying GoS Manager enables network operators to:
- Protect critical or real-time applications
- Detect Cell ID and WiFi access for optimal routing
- Protect revenue generating services
- Reduce service assurance costs
- Increase service profitability
- Run M2M services across shared links with guaranteed quality
- Reduce costs through efficient network optimisation and management
- Generate revenue with assured, sticky services
GoS 360° provides the only way in which network operators can accurately prioritise real-time M2M traffic at source, before it traverses the network.
