CACHING OF ANNOUNCEMENTS AT THE EDGE OF A PACKET SWITCHED TELECOMMUNICATION NETWORK
First Claim
1. A method of sending an announcement to user equipment, by an access server, the access server in use operating in a packet switched telecommunication network, the method comprising:
- receiving the announcement from a media source operating in said packet switched network;
receiving a caching indication associated with said announcement from said media source, indicating an instruction for the access server to initialize caching of said announcement;
caching the announcement in a caching unit associated with the access server in response to the received caching indication and the received announcement;
receiving an instruction from the media source to send said cached announcement towards the user equipment;
retrieving the cached announcement from the caching unit; and
sending the retrieved cached announcement towards the user equipment,characterized in thatthe announcement and the caching indication are embedded in an announcement media stream, the method further comprising;
extracting the announcement from the announcement media stream.extracting the caching indication from the announcement media stream.

Abstract
A method and an access server operating in a packet switched telecommunication network, such as a Voice over Internet Protocol (VoIP) network, for distributing an announcement to user equipment. The method comprises receiving an announcement from a media source, receiving a caching indication from the media source to allow caching of the announcement and sending the received announcement to the user equipment. The access server can cache the announcement in a caching unit associated with the access server on receipt of the caching indication and the announcement. Furthermore a method and a media source cooperating with the access server for generating an announcement and a caching indication to allow the access server to cache the announcement.

6. A method of generating an announcement by a media source, the media source operating in a packet switched telecommunication network such as a Voice over Internet Protocol (VoIP) network, the method comprising:
-
receiving a first instruction to generate an announcement; sending the announcement to an access server operating in said packet switched network; and generating a caching indication associated with said announcement; sending the caching indication to the access server for allowing the access server to cache the announcement in a caching unit associated with the access server; receiving a second instruction to generate said announcement; and sending an instruction to the access server for sending the cached announcement to user equipment, characterized in that said announcement is send in an announcement media stream, and wherein the step of sending the caching indication comprises embedding the caching indication in the announcement media stream - View Dependent Claims (7, 8, 9, 12, 13)
