Problems solved by technology
eNodeB+ is not connected to the core network (CoreNet, "CN" for short) node of the CS domain, such as the Mobile Switching Center (MobileSwitchingCenter, "MSC" for short) / VisitorLocationRegister ("VLR" for short), so it cannot provide CS domain alone Business

The invention relates to the field of wireless communication and discloses a method for establishing and triggering calls of a circuit domain and a system and a device thereof, which can reduce the time delay of the establishment of business in a CS domain. In the invention, during eNodeB plus in an evolution network processes a call issued by UE, if the call is confirmed to be the call of the CS domain, information required by UE to establish the call of the CS domain is sent to a traditional network where the RNC called by the UE is processed; the RNC then utilizes the information obtained by eNodeB plus to establish the call of the CS domain for UE.
Description
Circuit domain call establishment and trigger method, system and device technical field The invention relates to the field of wireless communication, in particular to the call establishment technology of the circuit domain. Background technique In 2006, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") passed the High Speed Packet Access ("HSPA") evolution research project. The evolved network architecture of HSPA is based on packet (PS) domain services. The PS domain service will provide high bit rate user rate and shorter call delay; the circuit (CS) domain service of the current third generation mobile communication (The Third Generation, referred to as "3G") system will no longer be optimized. In the evolved network of HSPA, all the functions of the radio network controller (Radio Network Controller, "RNC" for short) of the existing 3G system are placed on the evolved base station node (eNodeB+). In this HSPA network...
