Abstract
The present invention relates to providing a generic control plane in a GTP mobility protocol in a core network. When a type of user plane is detected, a user plane parameter is provided in a control plane message header. The user plane message indicates the type of user plane. Functions, parameters and messages are provided according to the indicated type of user plane. Thus, e.g. easier hand over between different access networks can be provided and an optimization of the user plane implementation in an edge node.
Claims12
A method in a core network node providing a generic control plane, referred to as GPRS Tunneling Protocol-Control (GTP-C), the generic control plane being in a GPRS Tunneling Protocol (GTP) mobility protocol, the GTP-C supporting both a GPRS Tunneling Protocol-User (GTP-U) user plane and a Generic Routing Encapsulation (GRE) based user plane, wherein the method comprises the following steps:
- detecting a type of user plane, the type of user plane being a GTP-U user plane or a GRE based user plane,
- providing a user plane parameter in a control plane message of the generic control plane, the user plane parameter indicating the type of user plane, and
- providing user plane functions, parameters and messages according to the indicated type of user plane to another node in the control plane message.
A communication node in a telecommunications network arranged to provide a generic control plane, referred to as GPRS Tunneling Protocol-Control (GTP-C), the generic control plane being in a GPRS Tunneling Protocol (GTP) mobility protocol, the GTP-C supporting both a GPRS Tunneling Protocol-User (GTP-U) user plane and a Generic Routing Encapsulation (GRE) based user plane, when a type of user plane is detected, the type of user plane being a GTP-U user plane or a GRE based user plane, said node comprising:
- a memory:
- a processor arranged to execute instructions stored in the memory to provide a user plane parameter in a control plane message header of the generic control plane, wherein the user plane parameter indicates the type of user plane, and
- the processor being further arranged to provide functions, parameters and messages according to the indicated type of user plane through a communications interface to another node.
