Embodiment Construction

[0077] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0078] In order to ensure the service continuity of the terminal stationed under the relay node, the embodiment of the present invention mainly starts from two aspects. The first aspect is also the most important aspect: to realize the problem of redistribution of the IP address of the relay node in the handover process, and to Reduce switching delay; on the other hand, establish a forwarding tunnel to reduce data packet loss.

[0079] An embodiment of the present invention provides a method for supporting relay node (RN) handover, the method including:

Abstract

The invention provides a method for supporting the switch of a relay node, a supplier base station and a relay node. The method for supporting the switch of the relay node comprises the following steps: a target supplier base station distributes a new IP (internet protocol) address and / or an address of an address distribution server for RN (radio navigation) when the RN is switched from a source supplier base station to the target supplier base station; the target supplier base station transmits the new IP (internet protocol) address and / or the address of the address distribution server to the RN through the other network elements. According to the method for supporting the switch of the relay node, the supplier base station and the relay node, the time delay for switching the relay node can be greatly reduced, so that the business continuity of a resident terminal of the relay node can be guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for supporting relay node switching, a donor base station and a relay node. Background technique [0002] In order to maintain the competitiveness of the third generation mobile communication system in the communication field, the standard working group of the third generation partnership project (3rd Generation Partnership Project, 3GPP) is working on the research of the evolved packet domain system (Evolved Packet System, EPS). The whole EPS system such as figure 1 As shown, it mainly includes two parts: Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) and Evolved Packet Core Network (Evolved Packet Core, EPC). The system's EPC can support users from the Global System for Mobile Communications (GSM) / Enhanced Data Rate GSM Service (EDGE) Radio Access Network (GSM EDGE radio access network, GERAN) ...
