METHOD FOR CONTROLLING DATA COMMUNICATION USING A NETWORK NODE GROUP IN A COMMUNICATION SYSTEM

摘要

The invention relates to a method, a system, a network node and a computer program for controlling data communication in a communication system. In the method a group comprising at least two serving nodes is formed in the communication network. At least one terminal node is associated with the group. Configuration information is received in a first serving node from a second serving node. A first message is received from a terminal node in the first serving node. In the first serving node is determined a second serving node from the group with at least a first identifier in the first message and the configuration information. The first message is sent from the first serving node to the second serving node. The first message is processed in the second serving node. A second identifier indicating the second serving node is provided to the terminal node. The second serving node is indicated in a second message from the terminal node.
