Embodiment 1

[0059] Embodiment 1 provides a method for establishing a CS domain service using a circuit domain fallback (CircuitSwitchFallBack, CSFB) technology, wherein the method for reporting frequency scanning information provided by the embodiment of the present invention is applied.

[0060] CSFB technology is a communication technology that provides voice services based on a circuit (CircuitSwitch, CS) domain network (such as the circuit domain in the second and third generation mobile communication systems). CSFB is also an LTE voice solution defined by the 3GPP standard. The LTE network is an all-IP network. In the early days of LTE, CS voice services could not be fully IP-based. In order to enable user terminals to perform CS services such as voice services when accessing LTE, CSFB technology was created.

[0061] According to the CSFB technology, when a user terminal accessing the LTE network wants to perform voice services, the network side makes the user terminal fall back to t...

Embodiment 2

[0080] Figure 4 It is a schematic diagram of a method process for reporting frequency scanning information in the process of establishing a CS domain service using the CSFB technology in Embodiment 2 of the present invention.

[0081] In Embodiment 2, the first frequency sweep timing threshold value and the second frequency sweep timing threshold value (hereinafter referred to as "threshold value") are equal, and the same frequency sweep timer (hereinafter referred to as "frequency sweep timer") is used to ”) timing. The first network is a GSM network, and the second network is a TD-SCDMA network (hereinafter referred to as "TD-S network").

[0082] Such as Figure 4 Shown, the method of embodiment two comprises the steps:

[0083] S401: The user terminal detects that the user has opened a preset application related to the CS domain by opening the phone book or the contact menu, etc.;

[0084] S402: Determine whether the current value of the timer is greater than the pres...

Abstract

The invention discloses a frequency sweep information reporting method and a user terminal, and aims to solve the problem that the time delay for business building is relatively longer due to longer frequency sweeping time as frequency sweeping is required to be performed firstly when business is built at the user terminal. The method comprises the following steps: the user terminal determines the frequency sweep information obtained from the last frequency sweep when frequency sweep information needs to be reported and time interval between the next time and the current time is no greater than a preset first frequency sweep timing threshold value; and the user terminal reports the frequency sweep information obtained from the last frequency sweep to a network side. As the user terminal reports the frequency sweep information obtained from the last frequency sweep at a time interval no greater than the preset first frequency sweep timing threshold value, the longer time delay for business building caused by frequency sweep is avoided.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method for reporting frequency scanning information and a user terminal. Background technique [0002] Frequency scanning is an operation that must be performed when the user terminal determines the network to be accessed during the communication process. Typically, the frequency sweep process includes: [0003] The user terminal scans all frequency points in the frequency band at a certain step interval according to the frequency band range supported by itself; [0004] The user terminal performs blind detection on the broadcast channel on the frequency point (the broadcast channel format, message format and content corresponding to different communication standards are different); [0005] If the detection is successful, the user terminal obtains information such as the cell identifier on the frequency point, resource allocation, etc., for the user terminal to use ...
