METHOD AND DEVICE FOR ADAPTING A DATA PATH FOR A MOBILE ENTITY IN A COMMUNICATION NETWORK

摘要

According to the invention, a method and a device for adapting a data path for a mobile entity (201) in a communication network are suggested. The communication network has at least one forwarding entity (203, 205) for providing data packets for the data path and a plurality of mobility binding entities (207, 209) for forwarding data packets on the data path, wherein a first mobility binding 10 entity (207) is allocated to the data path for the mobile entity (201) according to binding information for the mobile entity (201). The method has a step receiving (101) a re-allocation request for re-allocating a second mobility binding entity (209) to the data path for the mobile entity (201), a step of updating (103) the binding information for the mobile entity (201) on the basis of the received re-15 allocation request, a step of forwarding (105) data packets received from the forwarding entity (203, 205) by the first mobility binding entity (207) to the second mobility binding entity (209) until the updated binding information is received at the forwarding entity (203, 205), and a step of forwarding (107) data packets from the forwarding entity (203, 205) to the second mobility binding entity (209) after the 20 updated binding information is received at the forwarding entity (203, 205).
