Problems solved by technology

[0022] When the MME of the RN is overloaded, the resources of the RN may be released, and the release of the resources of the RN will cause the service interruption of the UE connected to the network through the RN, which undoubtedly brings a bad access experience to the UE user. decline in quality

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0056] Figure 4 It is a flow chart of the overload control method of the relay system in Embodiment 1 of the present invention, such as Figure 4 As shown, the overload control method of the relay system in this example specifically includes the following steps:

[0057] In step 401, the MME decides to offload the RN, and the MME sends a UE context release command to the DeNB, which carries a reason, indicating that the reason for the release is offloading. Because the current system load is high, if it exceeds the set load threshold, the network side determines that the RN needs to be offloaded for the sake of protection of the communication system.

[0058] In step 402, the DeNB releases the RN according to the instruction of the ne...

Abstract

The invention discloses an overload control method of a relay system. The method comprises: after a donor eNodeB (DeNB) receives a relay node (RN) unloading message sent by a network side or an overload start message, user equipment (UE) with access to an RN is unloaded according to an unloading strategy configured by the DeNB itself. Meanwhile, the invention also discloses a relay system's an overload control system for realizing the method. The overload control system includes an RN, a DeNB and UE. More specifically, the DeNB is used for unloading the UE with access to the RN according to an unloading strategy configured by the DeNB itself after receiving of an RN unloading message sent by a network side. According to the invention, it can be ensured that services of some UE with high-priority services or high-priority users will not be interrupted; and thus service continuity of the UE accessed by an RN is ensured to the greatest extent. Moreover, the system and the method can be realized without need to carry out major changes on a current communication system, thereby ensuring convenience of realization of the provided technical scheme.

Description

technical field [0001] The invention relates to an overload control technology in a wireless communication system, in particular to an overload control method and system for a relay system. Background technique [0002] In order to maintain the competitiveness of the third generation (3G, 3rd Generation) mobile communication system in the communication field, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project,) standard working group is working on the Evolved Packet System (EPS, Evolved Packet System) research. figure 1 is a schematic diagram of the structure of the evolved packet system, such as figure 1 As shown, the entire EPS system includes two parts: Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) and Evolved Packet Core Network (EPC, Evolved Packet Core). EPC can support user access from GSM EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network) and Universal Ter...
