Detection of the mobility management function used by the network

A method for detecting the IP mobility management function used by an network, the method being performed by a mobile node and comprising:

• transmitting a probe message to the network in form of an IP packet, wherein the IP header of the probe message destines the probe message to an IP address of the mobile terminal,
• receiving the probe message from the network, and
• detecting, based on a comparison of the transmitted probe message and the received probe message whether the network uses a network-based mobility management function for the mobile node or not.

A mobile node for detecting the IP mobility management function used by a network, the mobile node comprising:

• a transmitter unit that transmits a probe message with IP header to the network, wherein the probe message is destined to an IP address of the mobile terminal,
• a receiver unit that receives the probe message from the network, and
• a processing unit that detects whether or not the network uses a network-based mobility management function for the mobile node based on a comparison of the transmitted probe message and the received probe message.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of the mobile node, cause the mobile node to detect the IP mobility management function used by an network for the mobile node, by:

• transmitting a probe message with IP header to the network, wherein the probe message is destined to an IP address of the mobile terminal,
• receiving the probe message from the network, and
• detecting based on a comparison of the transmitted probe message and the received probe message whether the network uses a network-based mobility management function for the mobile node or not.
