During the attachment procedure, the device (here the modem contained in the scooter) will scan for the nearest cell tower to connect to (1).

Now, let’s look at an overview of LTE architecture. Roaming scenarios are very important for IoT use cases where devices are deployed all around the world. Based again on the MCC and MNC contained in the IMSI, that traffic is home routed and the IMSI’s owner can decide whether or not to authorize the device to connect to the network while roaming. While roaming, the attachment procedure is similar – the only difference is, initially the scooter will interoperate with the visited operator core network (known as the Visited Public Land Mobile Network (VPLMN)). These act as breakout entities towards the internet. Once the authentication procedure is completed, a set of dedicated tunnels known as dedicated bearers (the red-dotted lines above), are established between the device and the user plane entities of the carrier network. In addition, the IMSI includes the Mobile Subscription Identification Number (MSIN) used to identify the subscriber within the carrier network.įor instance, the following IMSI, ` 3102401234567890`, contains MCC `310` and MNC `240`, which identify `T-Mobile` as the carrier, and MSIN `1234567890`, identifying a specific account number in that network.

The IMSI contains the Mobile Country Code (MCC) and the Mobile Network Code (MNC) as prefixes, which are used for identifying the SIM card’s carrier network. The core network receives the signal from the device, including the information contained in the SIM card (such as the International Mobile Subscriber Identity (IMSI)) and authenticates/authorizes the device to connect to the network (the green line in the picture below). In a very simplified view, your scooter connects to the nearest Radio Access Network (RAN), acting as the first point of contact between the device and the carrier network. Attachment is needed to authenticate and authorize the device to connect to a network, and ultimately grants the device internet connectivity. This procedure is named attachment in the telecommunications domain. The Super SIM represents the physical device containing the “secrets” utilized to register with the network. Well, the first thing you need to do is to buy a Super SIM from Twilio. Maybe you want your customers to be able to unlock it and use it. Let’s assume you have an IoT device – a scooter for instance – and you’d like internet connectivity.

Additionally, we help provide insights which are extremely useful when you start scaling your fleets of devices.

Our Mobile Core allows us to meet developers’ expectations for:īy owning our Mobile Core, Twilio gives you and your customers the lifecycle control you really need for your fleets of IoT devices.įlexibility is another key element we can provide you: with our REST APIs you can build new use cases that weren’t possible – or economically feasible – before. You may be wondering: what’s Twilio doing with a Mobile Core?

Unlike most other deployments, our Mobile Core implementation is 100% software based and deployed on Amazon Web Services. In the past decades, 2G/3G/4G network functions have been implemented as dedicated hardware-based appliances. The 3rd Generation Partnership Project (3GPP) is the primary group that focuses on mobile network architectures and protocols. What is a Mobile Core?Ī Mobile Core comprises different network functions defined by several standardization bodies. Let’s talk about Twilio’s Mobile Core implementation – along with how it helps you. A Mobile Core provides all the functionality required to enable a device with wireless capabilities to connect to the cellular network independent of its radio technologies (4G, 5G, etc.). At Twilio’s 2019 SIGNAL Conference, we presented the Twilio Mobile Core as the engine behind Twilio’s Super SIM.
