Abstract
Methods, an uplink module (130), downlink module (160), an entry module (170) and a management module (147) for managing packets in a communication system (100) based on Software Defined Networking are disclosed. A data plane of the communication system (100) comprises a forwarding module (140), a service module (145) and the entry module (170) and a control plane of the communication system (100) comprises the management module (147). The entry module (170) receives (8) an Internet Protocol “IP” packet from the peer device (180), wherein the IP packet includes a destination IP address associated with the mobile device (120). The entry module (170) obtains (9), from the management module (147), a location value specifying the radio network node (110) associated with the destination IP address. The entry module (170) associates (10) the location value with the IP packet, wherein the location value is related to a location tag name, indicating the radio network node (110) that serves the mobile device (120), thereby obtaining a packet. The entry module (170) sends (11) the packet, via the forwarding module (140), towards the radio network node (110) as indicated by the location value…
