Embodiment 1

[0024] This embodiment provides an execution method for multi-mode terminal network selection, which is applicable to multi-mode terminals, such as figure 1 As shown, the method includes:

[0025] After the terminal is turned on, it initiates a joint registration process through the second network to register, and resides in the second network after registration, that is, a network supporting data domain services.

[0026] Step 101, judge whether to execute the CS domain service through CSFB according to the CS domain service setting mode; if it is determined that the CS domain service is executed through the CSFB method, then perform step 102; way to execute.

[0027] Step 102, execute in CSFB mode, enter the first network to perform circuit domain services, and after performing circuit domain services, judge whether there are pending unfinished data domain services in the second network; If there is no pending unfinished data domain service, continue to reside on the first...

Embodiment 2

[0030] This embodiment specifically describes a method for executing a multi-mode terminal network selection. This method is applicable to a terminal, and the terminal may specifically be an LTE multi-mode terminal. It should be noted that since the LTE network only supports data In this example, the LTE network represents the first network that only supports data domain services as an example; WCDMA, GSM, CDMA and other networks support both circuit domain services and data domain services, that is, networks that at least support circuit domain services, so in In this embodiment, the second network is taken as an example for description.

[0031] After the LTE multi-mode terminal is turned on, it initiates a joint registration process through the LTE network to register, and resides in the LTE network after registration.

[0032] like figure 2 As shown, the method includes:

[0033] Step 201, the terminal judges whether to execute the CS domain service through the CSFB met...

Embodiment 3

[0064] This embodiment provides a multi-mode terminal 300, the multi-mode terminal may specifically be an LTE multi-mode terminal, such as image 3 As shown, the terminal 300 includes: an execution determination unit 31 , a circuit domain execution unit 32 , and a network selection unit 33 .

[0065] The execution determining unit 31 is used to judge whether to implement the CS domain service through the CSFB method according to the CS domain service setting method; the CS domain execution unit 32 is used to determine whether the CS domain service is executed through the CSFB method when the execution determining unit 31 determines that the CS domain service is executed through the CSFB method, Entering the first network to perform circuit domain services, and after performing circuit domain services, judging whether there are pending unfinished data domain services on the second network, wherein the first network supports at least circuit domain services, and the The second n...

Abstract

The embodiment of the invention discloses an executing method of multimode terminal network selection and a multimode terminal, relating to the technical field of communication and solving the technical problem that the multimode terminal is frequently switched when a CSFB mode is adopted in the prior art. The method comprises the steps of: judging whether a circuit domain service is executed by the CSFB mode according to a circuit domain switch setting mode; if so, entering a first network executing circuit switch service, and judging whether a hung-up uncompleted data domain service exists in a second network after the circuit domain service is completely executed, wherein the first network at least supports the circuit domain service, and the second network supports the data domain service; and if the hung-up uncompleted data domain service exists in the second network, continuing to remain the first network. The embodiment of the invention is mainly applied to the terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an LTE (Long Term Evolution, Long Term Evolution) multi-mode terminal network access method and a multi-mode terminal. Background technique [0002] An LTE terminal is a multi-mode terminal that supports LTE / WCDMA (Wideband-Code Division Multiple Access) / GSM (Global System for Mobile Communications) network mode, or LTE / CDMA (Code-Division Multiple Access) Access, code division multiple access) network mode. [0003] LTE is a network that simply supports data domain services. Since the processing performance of the LTE network for data domain services is superior to that of WCDMA, GSM, CDMA and other networks that mainly support voice domain services, operators generally Set the priority of LTE network to be higher than that of WCDMA, GSM, and CDMA networks, and LTE terminals will also choose to reside on LTE networks first. However, unlike the current GSM...
