Cause value encoding for handovers in a wireless communications network
First Claim
Patent Images
1. A first network node for use in a wireless network, the first network node being adapted to:
- forward information on movements of a wireless device to a second network node over an interface for a handover (HO) signalling;
wherein the information on movements is represented by a HO cause value in a first field that uses an interface-dependent encoding and a HO cause value in a second field that uses an interface-independent encoding.

Abstract
According to an embodiment there is provided a first network node (122) for use in a wireless network (100), the first network node (122) being adapted to forward information on movements of a wireless device to a second network node (124) over an interface (106; 108); wherein the information on movements is represented by a cause value in a first field that uses an interface-dependent encoding and a cause value in a second field that uses an interface-independent encoding. A corresponding second network node and methods of operating the network nodes are also provided.
