Problems solved by technology

[0011] In the process of implementing the present invention, the inventor found that the implementation in the prior art has the following problems: in the scenarios of CS fallback and ISR, since the MME and SGSN are not aware of the change of the SGs or Gs interface, they cannot correctly Notify MSC / VLR to separate UE

Embodiment Construction

[0037] Embodiments of the present invention provide a method for separating circuit domain CS services back to traditional networks, such as image 3 shown, including:

[0038] Step s301, the first mobility management entity generates a detach indication message carrying a detach type.

[0039] Step s302, the first mobility management entity sends the detach instruction message to the second mobility management entity, so as to instruct the second mobility management entity to detach the user terminal according to the detach type carried in the detach instruction message.

[0040] By using the embodiment of the present invention, the detachment indication message sent by the first mobility management entity to the second mobility management entity carries the detachment type, so that the second mobility management entity performs the detachment according to the detachment type carried in the detachment indication message. The separation processing of the user terminal can ens...

Abstract

The embodiment of the invention discloses a method, a system and equipment for separating in a circuit switched domain (CS) service fallback conventional network. The method comprises the following steps that: a first mobility management entity generates a separation indication message carrying a separation type; and the first mobility management entity sends the separation indication message to asecond mobility management entity to indicate the second mobility management entity to separate a user terminal according to the separation type carried in the separation indication message. By usingthe method, the system and the equipment, the separation indication message sent to the second mobility management entity by the first mobility management entity carries the separation type, which ensures that the second mobility management entity performs the separation processing on the user terminal according to the separation type carried in the separation indication message, and can ensure that the user terminal is separated correctly in a separation flow in a CS Fallback and ISR scene.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and equipment for separating circuit domain services back to traditional networks. Background technique [0002] GPRS (General Packet Radio Service, General Packet Radio Service) / UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) is a mobile communication network defined by 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project). Including RAN (Radio Access Network, wireless access network) and CN (CoreNetwork, core network) two parts. CN is logically divided into CS (Circuit Switched Domain, circuit switched domain) and PS (Packet Switched Domain, packet switched domain). The CS domain mainly handles voice services, and the PS domain mainly handles packet services. The signaling plane control entity of the CS domain is MSC (MobileSwitch Center, mobile switching center) / VLR (V...
