Embodiment 1
[0063] The terminal is turned on to access the network. At this time, the first core network connected to the macro base station is not allowed to access new terminal users due to the heavy load. At this time, the macro base station will receive an overload indication from the first core network, causing the macro base station to The station cannot access the terminal. At this time, the macro base station may not have reached full capacity. At this time, the high-level control of the macro base station sends the request message of the terminal user to the The high-level processing of the small cell base station, the high-level of the small cell base station will create the context of the end user, and establish the connection with the second core network connected to the small cell base station. As a result, the service data of the new end user first passes through the X2 interface, and then passes through the GTPU channel from the small cell base station to the second core net...

The invention provides a method for balancing a load of an EPC (extended parity checking) gateway. The method comprises the following steps of receiving first core network overloading information transmitted from a first core network by using an acer station; establishing a connecting link between the acer station and a small cell base station by using an X2 interface; transmitting connecting requesting information of a terminal to the small cell base station by using the acer station; establishing a context bearing channel of the terminal by using the small cell base station; establishing connection between a second core network connected to the small cell base station and the terminal by using the small cell base station; and performing communication transmission between the terminal and the second core network by using the X2 interface and the small cell base station. The problem that the load of the core networks which are connected with the acer station is over high and the core networks are even overloaded so that user terminals cannot join up the core networks is solved. By the method, the gateway load of the core networks connected to the acer station can be well reduced; the user terminals which require connection establishment can join up the networks so as to carry out communication transmission; and furthermore, radio resources of the acer station and redundant upper-layer bearing resources of the small cell base station can be sufficiently utilized.
Description
technical field [0001] The invention relates to mobile communication technology, in particular to a method for balancing the load of an EPC gateway. Background technique [0002] In the field of mobile communication, EPS (Evolved Packet System, Evolved Packet System) is gradually developing. The EPS system mainly includes two parts: E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) and EPC (Evolved Packet Core, Evolved Packet Core Network). The EPC of the system can support user access from GERAN (GSMEDGE radio access network, GSM EDGE wireless access network) and UTRAN (Universal Terrestrial Radio Access Network, universal terrestrial radio access network). In the EPC packet core network, it includes HSS (Home Subscriber Server, home user data server), MME (Mobility Management Entity, mobility management unit), S-GW (Serving Gateway, serving gateway), P-GW (PDNGateway, Packet Data Network Gateway), SGSN (Servi...
