Technology for method for reducing the number of unsuccessful service change attempts of a first mobile terminal is presented. The first mobile terminal is connectable via a mobile network to a further terminal by establishing a call connection for providing a first service or by establishing a call connection for providing a second service. The first mobile terminal receives a first indication signal indicating that a service change to the second service is temporarily unavailable from a mobile network node administrating an established call connection for providing the first service. In response to receiving the first indication signal, the first mobile terminal refrains from requesting a service change to the second service until reception of a further indication signal from the mobile network node indicating that a service change is available again.

Mobile network node and mobile terminal for performing a signalling method in a mobile network

A method for reducing the number of unsuccessful service change attempts of a first mobile terminal is presented. The mobile terminal () is connectable via a mobile network to a further terminal by establishing a call connection for providing a first service or by establishing a call connection for providing a second service. The method comprises the following steps performed by the first mobile terminal (): receiving (S) a first indication signal () indicating that a service change towards the second service is temporarily unavailable from a mobile network node () administrating an established call connection for providing the first service, and in response to receiving the first indication signal () refraining (S) from requesting a service change towards the second service until reception of a further indication signal () from the mobile network node () indicating that a service change is available again.

Methods, mobile network node and mobile terminal for reducing the number of unsuccessful service change requests performed by the mobile terminal

A technique is provided for use by a user terminal or mobile services switching center (MSC) for responding to a request to switch an on-going call from speech mode to multimedia mode within a wireless communication network conFig.d to automatically disconnect a call if a requested mode switch is not confirmed within a predetermined period of time specified by a call drop timer. In one example, the terminal or MSC activities an automatic response timer upon receipt of a request from a user to switch an on-going call from speech to multimedia, with the timer set shorter than the call drop timer. The user receiving the request is then prompted to accept or decline the request. If no response is received before expiration of the automatic response timer, the terminal or MSC automatically declines the request on behalf of the user so that the call drop timer does not expire.

The invention relates to methods and devices that enable to request more than one service during call set-up. To this end a new indicator is introduced into a request message sent to a database storing subscriber data, for indicating that at least one further request message is sent and a response indicator that a database is adapted to handle said indicator. Furthermore a set of rules is defined how different responses from the database are processed to enable said request.
