Remote access to a device in an IMS system with a second media access channel

摘要

Remote access of content in an IMS system is described. A first IMS channel is established between, for example, a user terminal and an IMS Gateway (IG) for control signaling. A second IMS channel is established between, for example, the user terminal and the IG for conveying the content being remotely accessed. Due to limitations in the network, Quality of Service (QoS, or bandwidth) reservations are handled differently on the originating and terminating sides. For example, on the originating side, a single QoS reservation is used for both the first and second IMS channels, whereas on the terminating side separate QoS reservations can be used for the first and second IMS channels.

1. A method for remote access of content in an Internet Multimedia Subsystem (IMS) communication system, the method comprising:
establishing a first IMS session between a user equipment (UE) and an IMS Gateway (IG) with an initial Quality of Service (QoS) reservation value equal to a first non-zero value; performing control signaling associated with remote access via the first IMS session; establishing a second IMS session between the UE and the IG with an initial QoS reservation value equal to zero and preventing a QoS reservation request from being sent to an access network of the UE, the first IMS session and the second IMS session being overlapping in time; modifying the initial QoS reservation value associated with the second IMS session, at the IG, to a second non-zero value associated with the content; and transmitting the content via the second IMS session.
