Method, system and radio access network nodes for user data connection re-establishment
First Claim
1. A method for establishing a bearer plane for a broadcast or multicast service session in a mobile telecommunication network comprising at least a first network node initiating a bearer plane establishment and a second network node receiving the bearer plane establishment from the first network node, the method comprising:
- establishing a bearer plane between a first network node and a second network node for a broadcast or multicast service session;
detecting a failure with an established bearer plane;
reselecting a second network node providing the broadcast or multicast service session; and
re-establishing the bearer plane with a selected second network node for continuing the broadcast or multicast service session.

Abstract
The invention discloses a method, system and radio access network nodes for establishing a bearer plane for a broadcast or multicast service session in a telecommunication network. In one embodiment, the addresses of all serving GPRS support nodes trying to establish a bearer plane along with the broadcast or multicast service session identifier are stored e.g. on a radio access network node. The radio access network node is e.g. a radio network controller (RNC) of the Universal Terrestrial Radio Access Network (UTRAN). If the bearer plane is, for some reason dropped, based on the stored information one node providing the broadcast or multicast service session is reselected and the bearer plane is re-established with the selected serving GPRS support node for continuing the broadcast or multicast service session.
