Abstract

Described is a combination of multi-operator and multi-remote administration tool (RAT) aggregation technologies with dynamic mobile operator selection. This allows for a best-in-class experience for mobile users. These techniques abstract the choice of mobile operators to provide the best coverage / user experience in the area local to the user, automate and dynamically switch between operators, and abstract the aggregation of the traffic between multiple RATs and/or operators. Overall, this solution improves the user mobile experience.

SEAMLESS AGGREGATION OF MULTI-REMOTE ADMINISTRATION TOOL AND MULTI-OPERATOR WIRELESS ACCESSES

ABSTRACT

Described is a combination of multi-operator and multi-remote administration tool

(RAT) aggregation technologies with dynamic mobile operator selection. This allows for

a best-in-class experience for mobile users. These techniques abstract the choice of mobile

operators to provide the best coverage / user experience in the area local to the user,

automate and dynamically switch between operators, and abstract the aggregation of the

traffic between multiple RATs and/or operators. Overall, this solution improves the user

mobile experience.

DETAILED DESCRIPTION

In heterogeneous mobile networks, multiple radio interfaces are available for the

user/device (e.g., Wi-Fi®, unlicensed 5G new radio, licensed 4G/5G, etc.), each of which

has respective bandwidth/latency/reliability characteristics. In addition, multiple operators

can service the same area with different levels of performance for a given technology, or

service the same area with completely different technologies.

Two distinct categories of problems emerge from this context. First, within a given

service provider, multi-remote administration tool (RAT) / access point (AP) solutions

require complex signaling and control plane efforts in order to set up a reliable aggregation

on the end device. Second, in a multi-operator approach, it is unlikely for different (usually

competing) service providers to partner together to allow the end user to seamlessly roam

between different mobile networks.

As such, techniques are presented herein that address how highly demanding

mobile users receive the best performance available regardless of the underlying

technology/operator, and without any human intervention needed on the device or software

configuration.

Figure 1 below illustrates an example high-level diagram of techniques described

herein.

Figure 1

The techniques described herein may involve a (portable) network device that

includes:

• Multiple wireless interfaces (e.g., Wi-Fi/4G/5G radios and connectivity on

unlicensed & licensed spectrums) for use as a backbone. These interfaces are

referred to herein as B1 … Bi … Bn.

• A wireless or wired interface for the end user to connect to and implement the

techniques. These interface(s) are designated as L1 … Li … Ln.

A cloud-native software (CNS) may be implemented as server side software hosted

in the cloud. The network device may connect to the CNS via the Bi wireless interfaces.

Figure 2 below illustrates a detailed workflow of techniques described herein.
