Embodiment 1

[0065] image 3 The flow chart of the method for locating CS domain fallback failure provided by the embodiment of the present invention specifically includes the following processing steps:

[0066] Step 301. When the terminal receives and receives a CS domain service request in the LTE network, it sends the CS domain service request to the base station.

[0067] In this step, since the terminal generally prefers the Long Term Evolution (LTE, Long Term Evolution) network when it is turned on, when the terminal in the LTE network receives and receives a circuit domain service request, for example, initiates the calling voice service or receives the called voice service, the terminal will The CS domain service request is sent to the LTE base station eNodeB.

[0068] Step 302, the base station forwards the circuit domain service request to the network node.

[0069] Wherein, the network node (MME, MobilityManagementEntity) is in the LTE network.

[0070] Step 303, the network...

Abstract

The invention discloses a method, device and system for locating the problem of circuit domain fallback failure, comprising: a terminal sends a request for receiving and receiving circuit domain services in an LTE network to a base station; receiving a circuit domain fallback instruction sent by the base station, and the circuit domain fallback The command carries the frequency point information of the wireless network and the measurement control information to be reported by the terminal; scan the frequency point signal in the frequency point information, and collect the measurement control information to be reported; When the preset access conditions are met, select to access the LTE network again, and send the collected measurement control information to be reported to the base station, and use the measurement control information to be reported to locate the reason for the CS domain fallback failure. By adopting the above-mentioned method provided by the embodiment of the present invention, the accurate positioning of the CS domain fallback failure problem is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and system for locating the problem of circuit domain fallback failure. Background technique [0002] At present, when the terminal is turned on, it is preferred to access the LTE network, but when using the LTE access, it cannot send and receive CS domain service signals. When the terminal needs to perform circuit domain (CS, CircuitSwitch) services (for example: initiate or receive voice services) under the LTE network, it is necessary to connect the currently used network from the LTE network to the circuit domain core network, that is, the 2G / 3G network , and can correctly process the ongoing packet domain service of the terminal in the LTE network, therefore, a Circuit Switched Fallback (CSFB, Circuit Switched Fallback) technology is generated. [0003] The existing process of the terminal falling back to the circuit domain core network o...
