According to another aspect of the present invention there is provided an arrangement in a communication system for provision of a service in response to a request from a client, the provisioning of the service requiring communication of data to a mobile user equipment, the arrangement comprising:
a service provisioning entity for receiving a service request from the client, the request identifying the mobile user equipment by means of an identifier;
storage means for maintaining information regarding possible associations between the identifier of the mobile user equipment and user plane addresses that can be used for user plane data transmissions in said communication system, wherein the storage is arranged to verify if a user plane address for communication of data can be found from the storage means based on the identifier, and,
if such a user plane address is found from the storage means, data associated with provisioning of the requested service to the mobile user equipment is communicated over a user plane connection associated with said address found from the storage means, and
if no user plane address can be found from the storage means based on the identifier, a new user plane connection is established and data associated with provisioning of the requested service to the mobile user equipment is communicated over said established user plane connection.
