Quality of service support for machine-to-machine applications

摘要

A Quality of Service functionality is provided for Machine to machine device communications that allows a single IMS session to support a plurality of different data streams. In one embodiment a single IMS session is used to support a plurality of different data streams that arise from a single application type, while in another embodiment, a single IMS session is used to support a plurality of different data streams across a plurality of different devices and applications. Through the use of a single IMS session, signaling is reduced and QoS can be offered without impacting a large number of nodes. An IMS User Agent is deployed to aid in providing this functionality.

1. A method of supporting Quality of Servicee, QoS, in an Internet Mulitimedia Subsystem, IMS, network comprising:
receiving, at a node in an IMS core network, a registration; receiving from a node associated with the received registration a request to create an IMS session to support a machine-to-machine data session; responsive to determining that a suitable IMS session already exists, modifying session information associated with the suitable IMS session to allow the suitable session to carry a content stream associated with the request to create a session, and to adjust an existing quality of service associated with the suitable session in accordance with the received request to create an IMS session.
