A communications system for conveying traffic of first and second types comprising: a first network entity being arranged to receive a request from a calling party to establish a communication channel for traffic to a called party identified in the request, the first network entity having means for determining a type of traffic identified in the request and for routing the request to the called party if the request is for traffic of a first type, and means for redirecting the request if the request is for traffic of a second type; and a second network entity arranged to receive the redirected request and having means for routing the request to the called party whereby a channel for traffic of the second type can be established via the second network entity.

Video traffic in a communications system

Ring-back content is provided to a mobile video caller willing to call a recipient in a process in which: the ring-back content is stored, a first communication leg is established between an intermediate network element and the mobile video caller, a second communication leg is established between the intermediate network element and the recipient, and the delivery of the ring-back content to the mobile video caller is started between the initiating of the mobile video call and answering to the call by the recipient. The delivery of the ring-back content may be lead by an early connect message to delay charging. On establishing the second communication leg, no connect message is passed to the caller, but the charging of the mobile video call is started.

Mobile video call response

A mechanism for controlling an establishment of a call from a calling party being located in a first communication network environment to a receiving party being located in a second network environment, comprise a determination whether or not information on media parameters supported by the calling party is received in an initialization message for the call, and if the information on media parameters supported by the calling party is not received, a transmission of a specific message based on a service change and fallback function to the receiving party, a receipt, in response to the specific message based on the service change and fallback function, of information on media parameters supported by the receiving party, processing of the information on media parameters supported by the receiving party and a completion of the establishment of the call in correspondence to the media parameters supported by the receiving party and by the calling party.
