Method and apparatus for remote access to a home network
First Claim
1. A method of establishing a Quality of Service QoS in an access network for a multimedia session between a home network and a remote device located outside said home network, wherein at least one of said remote device and home network is connected to said access network, comprising the following steps:
- receiving a session invite message from the remote device for device discovery and optional browsing for media in the home network during a first part of the session, enforcing a QoS in the access network for the first part of the session,receiving a session re-invite message from the remote device to update the QoS for media communication with a selected home device in the home network during a second part of the session,determining QoS requirements for the second part of the session based on session parameters for said media communication, andenforcing an updated QoS in the access network for the media communication in the second part of the session to meet the determined QoS requirements.

Abstract
A method and apparatus for establishing a Quality of Service QoS in an access network for a multimedia session between a home network and a remote device located outside the home network. At least one of the remote device and the home network is connected to the access network. When a session invite message is received from the remote device for device discovery in the home network, a default QoS is enforced in the access network. When a session re-invite message is received from the remote device for media communication with a selected home device in the home network, the QoS requirements are determined for the media communication based on session parameters exchanged during the setup of the media communication. An updated QoS is then enforced for the session in the access network based on the determined QoS requirements.

9. A communication device for accessing a home network acting as a remote device when located outside said home network, wherein at least one of said communication device and home network is connected to an access network, comprising:
-
a memory; a processor; a sending unit for sending a session invite message, using the processor, to a multimedia gateway in the home network, for device discovery and optional browsing for media in the home network during a first part of a multimedia session, wherein a Quality of Service QoS is enforced in the access network for the first part of the session, and a determining unit for determining, using the processor, whether the QoS must be updated for media communication with a selected home device in the home network during a second part of the session, wherein the sending unit sends a session re-invite message to said multimedia gateway to update the QoS for the media communication with the selected home device, wherein the updated QoS is enforced in the access network for the second part of the session. - View Dependent Claims (10)

11. A session control node in a multimedia services network for enabling access to a home network for a remote device located outside said home network, wherein at least one of said remote device and home network is connected to an access network connected to said multimedia services network, comprising:
-
a memory; a processor; a receiving unit for receiving a session invite message, using the processor, from the remote device, directed to the home network, for device discovery and optional browsing for media in the home network during a first part of a session, and receiving a session re-invite message from the remote device, directed to the home network, for media communication with a selected home device in the home network during a second part of the session, a Quality of Service QoS enforcing unit for enforcing, using the processor, a QoS in the access network for said first part of the session, and a QoS updating unit for updating, using the processor, the QoS for said second part of the session based on session parameters for said media communication, wherein the QoS enforcing unit enforces the updated QoS in the access network for the second session. - View Dependent Claims (12, 13, 14, 15, 16, 17)
