Problems solved by technology

The eNodeB+ is not connected to the core network (Core Net, "CN" for short) node of the CS domain, such as the mobile switching center (Mobile Switching Center, "MSC" for short) / visitor location register (Visitor Location Register, "VLR" for short), so Cannot provide services in CS domain alone

Embodiment Construction

[0041] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] The first embodiment of the present invention relates to a CS domain call establishment method. In this embodiment, the UE is an R6 or previous version UE, the evolved network currently accessed by the UE is stand-alone Evolved HSPA UTRAN, and the UE initiates a CS domain call to the eNodeB+ of the evolved network. The eNodeB+ is connected to the RNC of the traditional network through an enhanced Iub / Iur interface, and the enhanced Iub / Iur interface can transmit Uplink Signaling Transfer Indication (Uplink Signaling Transfer Indication) messages and Downlink Signaling Transfer Request (Downlink Signaling Transfer Request) messages. The specific call establishment process is as image 3 Shown.

[0043] When the UE needs to initiate a CS ...

Abstract

The invention relates to the field of wireless communication, and discloses a circuit domain call establishment and trigger method, system and equipment, which reduce the time delay of CS domain service establishment. In the present invention, when the eNodeB+ in the evolved network processes the call initiated by the UE, if it determines that the call is a CS domain call, it sends the information required by the UE to establish the CS domain call to the RNC in the traditional network that processes the UE call , the RNC uses the information obtained from the eNodeB+ to establish a CS domain call for the UE.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to the call establishment technology in the circuit domain. Background technique [0002] In 2006, the 3rd Generation Partnership Project ("3GPP") passed the High Speed ​​Packet Access ("HSPA") evolution research project. The evolution of HSPA's network architecture is based on packet ( PS) domain services. For PS domain services, it will provide high bit rate user rate and shorter call delay; for the current third generation mobile communication (The Third Generation, "3G") system circuit (CS) domain services Will no longer be optimized. [0003] In the evolved network of HSPA, all 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 architecture, the eNodeB+ is directly connected with a Serving GPRS Support Node (Serving GPRS Support Node, ...
