REMOTE ACCESS TO A DEVICE IN AN IMS SYSTEM WITH A SECOND MEDIA ACCESS CHANNEL
First Claim
1. A method for remote access of content in an Internet Multimedia Subsystem (IMS) communication system, the method comprising:
- establishing a first IMS channel with a device having access to said content;
performing control signaling associated with said remote access of said content via said first IMS channel;
establishing a second IMS channel with said device having access to said content using a Quality of Service (QoS) reservation value equal to zero; and
receiving said content via said second IMS channel.

Abstract
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.
