Embodiment Construction

[0056] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0057] like figure 1 As shown, this embodiment provides a CSFB call failure missed call reminder method, including:

[0058] Step S10, sending a paging request to the called mobile terminal.

[0059] When the called mobile terminal has an incoming call, the MSC attached to the calling party sends a call request to the MSC attached to the called mobile terminal; the MSC attached to the called mobile terminal sends a paging request to the MME, and the call request includes the calling number and the called number. number; the MME sends a paging request to the called mobile terminal.

[0060] Step S20, receiving an extended service request from the called mobile...

Abstract

The invention discloses a method and a device for reminding a CSFB call failure of a missed call. The method includes: sending a paging request to the called mobile terminal; receiving an extended service request from the called mobile terminal according to the paging request; sending an indication of the called mobile terminal cell fallback to the evolved base station eNB, Make the eNB instruct the called mobile terminal to perform cell fallback, and start timing at the same time; receive the cell fallback failure information from the called mobile terminal; determine whether the interval time is less than the preset time, if so, then Send missed call information to the called mobile terminal. In the method, when the calling call fails, the called mobile terminal obtains a missed call reminder, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a device for reminding a CSFB call failure of a missed call. Background technique [0002] A typical CSFB (Circuit Switched Fallback, circuit domain fallback) service process mainly includes joint attachment, location update, calling (MO) CSFB process, called (MT) CSFB process, and detachment. The attachment procedure of the terminal with the CSFB function enabled is implemented based on the joint GPRS (General Packet Radio Service, General Packet Radio Service) / IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) attachment procedure. [0003] The attach request message sent by the multi-mode single-standby terminal to the MME (Mobility Management Entity, mobility management entity) carries an indication of supporting the CSFB function. After receiving the joint attachment request from the ...
