Embodiment 1

[0059] The first embodiment provides a method for establishing a CS domain service using a circuit switch fall back (CSFB) technology, in which the method for reporting frequency sweep 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 (Circuit Switch, 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, the IP-based CS voice service could not be fully realized. In order to enable user terminals to perform CS services such as voice services when LTE accesses, CSFB technology was created.

[0061] According to the CSFB technology, when a user terminal connected to the LTE network needs to perform voice services, the network side will make the user terminal fall back to the...

Embodiment 2

[0080] Figure 4 It is a schematic diagram of the method of reporting frequency sweep information in the process of establishing a CS domain service by using the CSFB technology in the second embodiment of the present invention.

[0081] In the second embodiment, the first sweep timing threshold and the second sweep timing threshold (hereinafter referred to as "threshold") are equal, and the same sweep timer (hereinafter referred to as "sweep timer") is used. ") 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 As shown, the method of the second embodiment includes the following 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 contact menu, etc.;

[0084] S402: Determine whether the current value of the timer is greater than the preset threshold value, if not, the whole process...

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 present invention relates to the field of communication technology, and in particular to a method for reporting frequency sweep information and a user terminal. Background technique [0002] Frequency sweeping is an operation that the user terminal must perform when determining the network to be accessed during the communication process. Generally, 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 of 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 the cell identifier, resource allocation and other information on the frequency point for the user terminal to use when establis...
