Problems solved by technology

[0003] When an existing dual-card dual-4G terminal user uses data services, especially when the user is in the process of moving, when the card 1 LTE network weak signal coverage area or a heavy network load area, the terminal's ability to transmit data services will be reduced. If the user experience is severely reduced, there will often be poor user experience such as video freezes and slow software downloads, and if the user wants to use the 4G network of card 2 for data services, the user must manually switch the data service to card 2. The user does not know whether the network coverage condition to which card 2 belongs satisfies the 4G camping conditions of the terminal. After the user manually switches the data service to card 2, the user equipment UE may camp on 4G but may not be able to camp on 4G, and It also takes time to perform LTE network search on card 2, resulting in users being unable to use data services normally during data service switching and network search, which will affect the user's 4G data service experience

no. 1 example

[0037] In the first embodiment of the present invention, a method for automatically switching data services of a dual-card terminal includes the following specific steps:

[0038] Step 1, monitoring the data transmission situation of the first network accessed through the main customer identification module SIM card;

[0039] Specifically, step 1 includes:

[0040] In the first network accessed through the primary SIM card, whenever the set period arrives, the total number of resource blocks allocated to the user equipment by the physical downlink control channel received within the set time period is divided by the set time period The number of times that the resource block is received within is obtained to obtain the average number of resource blocks.

[0041] The set cycle includes: the switching cycle between cards in the connected state of the user equipment.

[0042] Step 2, judging whether the first network needs to be replaced according to the monitoring results;

no. 8 example

[0095]The eighth embodiment of the present invention, this embodiment introduces a dual-card 4G terminal on the basis of the seventh embodiment, including the device for automatically switching data services of the dual-card 4G terminal in the seventh embodiment. The terminal in this embodiment can be understood as an entity device.

no. 9 example

[0096] The ninth embodiment of the present invention, this embodiment is based on the above embodiments, taking a specific dual-card 4G mobile phone as an example, combined with the attached image 3 An application example of the present invention is introduced.

[0097] In this embodiment, the SIM cards in the dual-card 4G mobile phone include card 1 and card 2.

[0098] like image 3 As shown, the 4G data service switching process of a dual-card 4G mobile phone is as follows:

[0099] Step 1, card 1 is inserted into the SIM card of China Mobile 4G, and card 2 is inserted into the SIM card of China Unicom 4G. Card 1 is connected to the 4G network as the main card to provide 4G data services, and card 2 is connected to the GSM network.

[0100] Step 2. Initially select card 1 for 4G data services and use card 1 to play video, download software or browse webpages.

[0101] Step 3: The mobile phone background counts the number of RB (Resource Block, resource block) in the do...

Abstract

The invention discloses a dual-card terminal, a method and device for automatically switching data services of the dual-card terminal. The method includes the following steps that: the transmission state of data passing through a first network into which a main client identification module SIM card is monitored; whether the replacement of the first network is required is judged according to monitoring results; when it is judged that the first network is required to be replaced, the other SIM card, adopted as a main SIM card, is connected into a corresponding second network, so that data services can be provided for a user, wherein the first network and the second network both accord with mobile communication standards higher than the fourth generation mobile communication standards 4G. Taking switching between different 4G networks as an example, with the method and device of the invention adopted, the terminal can automatically and quickly switch 4G data services to the other SIM card when a 4G network to which a main SIM card belongs is incapable of providing excellent data transmission, wherein the main SIM card provides 4G data services currently, and therefore, a 4G network of the other SIM card can be utilized to perform data services.

Description

technical field [0001] The invention relates to the technical field of data services in mobile communications, in particular to a dual-card terminal and a method and device for automatically switching data services thereof. Background technique [0002] The existing dual-card dual-standby 4G (the fourth-generation mobile communication standard, the so-called 4G network refers to the LTE network) terminal does not support dual 4G standby, even if it uses two SIMs that both support 4G data services (Subscriber Identity Module, customer identification module) card, the SIM card is referred to as the card hereinafter, and there is only one card as the main card at the same time to run 4G data services. For example: card 1 is the main card and is on standby on the 4G network, while card 2 is on standby on the 2G or 3G network. If you want to use the 4G data service of card 2, you must manually switch the data service of the card to make card 2 the main card. And start the LTE (L...
