Abstract

Provided is a method and system in a mobile wireless communication network for jointly determining computational offloading and data prefetching for a plurality of user equipments (UEs) in the mobile network. The method includes using a decision module in the mobile wireless communication network to process data indicative of mobile wireless communication network status including statuses of one or more UEs attached to the network. The decision module is configured to determine if the status of the mobile wireless communication network including said one or more UEs is sufficient to support joint computational offloading and data prefetching by at least one of the UEs. In the case that a positive determination is made, the decision module transmits a message to a UE to enable it to offload part of its computational load to one of a network edge computing node, a mobile wireless communication network server, and server in a network connected to the mobile wireless communication network; and to prefetch data to one of the network edge computing node, the mobile wireless communication network server, and a mobile wireless communication network data cache.

First claim

The invention claimed is:

1. A method in a mobile wireless communication network of jointly determining computational offloading and data prefetching for a plurality of user equipments (UEs), the method comprising:
at a decision module provided in the mobile wireless communication network:
processing data indicative of mobile wireless communication network status including statuses of one or more UEs attached to the network; and
determining if the status of the mobile wireless communication network including said one or more UEs is sufficient to support joint computational offloading and data prefetching for at least one of the UEs; and

in response to said determination at the decision module:
enabling a UE to offload part of its computational load to one of a network edge computing node, a mobile wireless communication network server, and server in a network connected to the mobile wireless communication network; and
prefetching data intended for said one of the plurality of UEs to one of a network edge computing node, a mobile wireless communication network server, and a mobile wireless communication network data cache.

2. The method of claim 1 , wherein the decision module is configured to operate only in a control plane of the mobile wireless communication network.

3. The method of claim 1 , wherein the decision module is embodied in a Mobility Management Entity (MME) of the mobile wireless communication network.

4. The method of claim 1 , wherein the data indicative of mobile wireless communication network status including statuses of one or more UEs attached to the network comprises data indicative of current statuses and data indicative of future statuses.

5. The method of claim 1 , wherein the data indicative of the statuses of one or more UEs comprises data indicative of one or more of UE buffer status and UE user quality of experience (QoE).

6. The method of claim 1 , wherein the data indicative of the mobile wireless communication network status comprises data indicative of one or more of mobility patterns of users in the network, networks loads, and network costs.

7. The method of claim 1 , wherein the decision module is configured to make a determination by solving the optimization problem:
