Problems solved by technology

[0007] Some terminals are limited by their chips and other reasons. The LTE module is set to work in the LTE only mode. The LTE network will not issue the measurement configuration of the different system B1 or B2 to the LTE-only terminal, nor will it issue the different system B1 or B2 measurement configuration to the terminal. The system switching command will cause the terminal to fail to switch or be redirected to a different system when the quality of the LTE network cannot meet the PS service requirements, which will affect the user's use effect

Embodiment 1

[0082] like figure 1 As shown, the embodiment of the present invention provides a method for PS connection state reselection, the method comprising:

[0083] 101. When the system information of a cell changes or a cell handover occurs in the same system, read the third system information block SIB3 issued by the network side, and read the sixth system information block SIB6 and / or the seventh system information block SIB7;

[0084] 102. Obtain the first threshold and LTE frequency point according to SIB3, and obtain the different-system reselection threshold and different-system frequency point according to SIB6 and / or SIB7;

[0085] 103. Carry out signal strength measurements on LTE frequency points and different system frequency points respectively;

[0086] 104. If the signal strength measured on the LTE frequency point is lower than the first threshold and the signal strength measured on the different system frequency point is higher than the different system reselection ...

Embodiment 2

[0089] like figure 2 As shown, the embodiment of the present invention provides a PS connection state reselection method, which is improved on the basis of Embodiment 1.

[0090] In this embodiment, the terminal is an LTE / GSM single-card dual-standby terminal as an example. The terminal can support LTE and GSM network standards. Before the terminal performs PS service state reselection, the terminal resides in the LTE network. And the data service is established in the LTE network, in the connected state, and the terminal resides in a cell without cell switching.

[0091] Wherein, the connection state refers to a signaling connection between the terminal and the network side, and is also called a service state in some scenarios, such as an RRC (Radio Resource Control, radio resource control protocol) connection.

[0092] It should be noted that, in the present invention, cell handover refers to the terminal moving from one cell to another cell in the region, and the two cell...

Embodiment 3

[0115] like image 3 As shown, the embodiment of the present invention provides a PS connection state reselection method, which is improved on the basis of Embodiment 1.

[0116] In this embodiment, the terminal is an LTE / UTRAN single-card dual-standby terminal as an example. The terminal can support LTE and UTRAN network standards. Before the terminal performs PS service state reselection, the terminal resides in the LTE network. And the data service is established in the LTE network, in the connected state, and the terminal resides in a cell without cell switching.

[0117] A method for PS connection state reselection, specifically comprising:

[0118] 301. When the network side changes a cell reselection parameter, broadcast in the cell;

[0119] 302. The cell paging the terminal, notifying the terminal that the cell reselection parameter changes;

[0120] 303. The terminal monitors the change of the cell reselection parameter, and reads the public cell reselection param...

Abstract

The invention discloses a method for reselecting a PS (Packet Switched) connected state and a terminal, belonging to the field of communication. When cell reselection parameters are changed at a network side or cell switching is carried out in the same system, an SIB3 (System Information Block) sent by the network side is read and an SIB 6 and / or SIB 7 is read, and signal strength is measured at an LTE (Long Term Evolution) frequency point and an inter-system frequency point, when requirements on a first threshold and an inter-system reselection threshold are met, cell reselection operation is carried out, and the defect of incapability of carrying out inter-system cell reselection operation under the condition of poor LTE signal quality when an LTE only mode is set in the traditional terminal is overcome, thus better service experience can be provided for a user.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a terminal for reselecting a PS connection state. Background technique [0002] In a communication network, currently commonly used voice services and short message services are mainly provided by a CS (Circuit Switched, Circuit Switched) domain, and data services are mainly provided by a PS (Packet Switched, Packet Switched) domain. [0003] With the development of technology, LTE (Long Term Evolution, long-term evolution) technology has been developed rapidly, and 3GPP (3rd Generation Partnership Project, third generation partnership project) is positioned to finally adopt LTE+IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) solution supports voice services. However, due to the relatively late deployment of the IMS by operators, an alternative CSFB (CS FallBack, CS FallBack) needs to be used for a long period of time. [0004] The technical implementation of CSFB ...
