BASE STATIONS ROUTING TRAFFIC OVER A PACKET BACKHAUL NETWORK TO MULTIPLE ROUTING ELEMENTS

摘要

System, methods, and networks are disclosed that allow base station systems (102) of a wireless communication network (100) to transmit outgoing traffic over a packet backhaul network (104) to multiple routing elements (106-107) on the MSC side of the network. A base station system (102) described herein identifies a primary routing element (106) and a backup routing element (107). The primary routing element (106) is the device to which the base station system (102) transmits outgoing traffic under normal operation, and the backup routing element (107) is an alternate to the primary routing element (106). To transmit traffic over the packet backhaul network (104), the base station system (102) monitors the availability of the primary routing element (106). If the primary routing element (106) is available, then the base station system (102) transmits outgoing traffic over the packet backhaul network (104) to the primary routing element (106). If unavailable, then the base station system (102) transmits outgoing traffic over the packet backhaul network (104) to the backup routing element (107).
