Abstract

The View Sharing Application is a technical solution for implementing web view sharing in the 3GPP (Third Generation Partnership Project) IMS (Internet Protocol Multimedia Subsystem). It is an application which allows the contents being displayed in a web browser on a local user equipment (UE) to be also seen synchronously on other browsers running on other UEs. The initiator of the web view sharing session has the control over which web page is displayed to all participants and is called „moderator". The other participants involved are called „passive participants". A) The web view sharing session can be initiated from an user equipment by browsing (sending an HTTP (Hypertext Transfer Protocol) request to get) a „start" web page in the web view sharing server which can be the Multimedia Resource Function (MRFC) or an Application Server (AS) in the IMS. On response to the HTTP request received, the server downloads a JAVA midlet to the UE. The midlet displays a window on the UE requiring the input of the link which will be accessed to start the web view sharing session and the identities of the other users to be invited to the session. When this data is entered by the local user, which will turn to be the moderator of the web view sharing session, a SIP (Session Initiation Protocol) dialog to the web view sharing server is established by the midlet. The data entered by the user is sent in the SIP INVITE message which initiates the set-up phase of the SIP dialog. Upon receipt of the SIP INVITE request containing the data entered, the web view sharing server takes the following actions:

The View Sharing Application is a technical solution for implementing web view sharing in the 3GPP (Third Generation Partnership Project) IMS (Internet Protocol Multimedia Subsystem). It is an application which allows the contents being displayed in a web browser on a local user equipment (UE) to be also seen synchronously on other browsers running on other UEs. The initiator of the web view sharing session has the control over which web page is displayed to all participants and is called "moderator". The other participants involved are called "passive participants".

A) The web view sharing session can be initiated from an user equipment by browsing (sending an HTTP (Hypertext Transfer Protocol) request to get) a "start" web page in the web view sharing server which can be the Multimedia Resource Function (MRFC) or an Application Server (AS) in the IMS. On response to the HTTP request received, the server downloads a JAVA midlet to the UE. The midlet displays a window on the UE requiring the input of the link which will be accessed to start the web view sharing session and the identities of the other users to be invited to the session. When this data is entered by the local user, which will turn to be the moderator of the web view sharing session, a SIP (Session Initiation Protocol) dialog to the web view sharing server is established by the midlet. The data entered by the user is sent in the SIP INVITE message which initiates the set-up phase of the SIP dialog. Upon receipt of the SIP INVITE request containing the data entered, the web view sharing server takes the following actions:

1. It browses the given link and downloads the corresponding web page.

2. It establishes the SIP dialog requested by the initiating UE according to IMS rules.

3. For each user ID (Identification), it sends an instant message (SIP MESSAGE request) containing an invitation text and instructions on how to join the conference.

B) Simultaneously, the web page downloaded in A) 1 is edited by the server in the way that all links contained in it are changed to point to the web view sharing server itself, in order that further browsing by the moderator of the view sharing session in under control of the server. A link to this version of the page is sent to the midlet on the UE initiating the web view sharing session during the establishment of the SIP dialog (in the 200 OK response for the INVITE). Another version of the page is generated in which all links are disabled. This version of the page will be sent to all passive participants in the web view sharing session.

C) When the SIP session between the UE initiating the conference and the web sharing server is set- up, the midlet module running on the initiating UE starts the web browser and requests the web page pointed by the link it received in the 200 OK response received for the INVITE it sent to establish the SI...
