Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
When the terminal is powered on or a subscriber identity card is inserted, the terminal performs an identification operation on the subscriber identity card, that is, the terminal reads an International Mobile Subscriber Identity (IMSI) field of the subscriber identity card, and can acquire a Mobile Country Code (MCC) and a Mobile Network Code (MNC).
After the user identification card is identified, the terminal carries out mobile network registration operation, after the terminal is registered to the mobile network, the terminal can obtain the MCC and MNC of the current terminal network side from the mobile network side which is currently registered, and can carry out identification of the mobile network according to the MCC and MNC of the terminal network side, and after the terminal is successfully registered on the mobile network, the terminal can use the data service provided by the movement of the terminal network.
When the terminal comprises at least two user identification cards, the method of the embodiment of the invention can realize the automatic switching of the main card and the auxiliary card, thereby improving the service quality of network service.
Referring to fig. 1, an embodiment of the present invention provides a handover method, including:
step 100, when the first user identification card is a main card, M second user identification cards are auxiliary cards; when the difference between the preset parameters of the N second subscriber identity cards and the preset parameters of the first subscriber identity card is greater than or equal to a first preset threshold value, switching one of the N second subscriber identity cards into a main card, and switching the first subscriber identity card into an auxiliary card; wherein M and N are integers greater than or equal to 1, and M is greater than or equal to N.
In the embodiment of the present invention, the preset parameter may be any parameter, for example, any one of the following parameters: signal strength, network rate, signal quality, network drop rate, etc.
In this embodiment of the present invention, when the first subscriber identity card is a primary card and M second subscriber identity cards are secondary cards, the method further includes:
acquiring preset parameters of the first subscriber identity module card;
switching the ith second subscriber identity module card to a main card; acquiring preset parameters of the ith user identification card; wherein i is an integer greater than or equal to 1 and less than or equal to M;
and continuing to execute the step of judging whether the difference between the preset parameter of the second subscriber identity module card in the ith page and the preset parameter of the first subscriber identity module card is greater than or equal to the first preset threshold value.
Wherein, obtaining the preset parameters of the ith second subscriber identity module card comprises:
network searching is carried out on the frequency band supported by the terminal corresponding to the network mode supported by the ith user identification card;
and when a frequency band supported by the terminal corresponding to the network mode supported by the ith second subscriber identity card is searched, acquiring preset parameters of the searched frequency band of the ith second subscriber identity card.
That is, when determining whether the difference between the preset parameter of the second subscriber identity card and the preset parameter of the first subscriber identity card is greater than or equal to the first preset threshold, it may be determined whether the difference between the preset parameter of the network mode currently registered by the second subscriber identity card and the preset parameter of the network mode currently registered by the first subscriber identity card is greater than or equal to the first preset parameter; or judging whether the preset parameters of the frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity card and the preset parameters of the frequency band supported by the terminal corresponding to the network mode supported by the first subscriber identity card are larger than or equal to a first preset threshold value.
It should be noted that, when acquiring the preset parameter, the terminal needs to register to the frequency band supported by the terminal corresponding to the corresponding network mode first, and if the preset parameter to be acquired is not the preset parameter of the currently registered network mode, the terminal needs to register to the network mode to be acquired first. For example, if the first subscriber identity card is registered to 4G and the second subscriber identity card is registered to 3G, at this time, if the first subscriber identity card is a master card and the second subscriber identity card is a slave card, it needs to be determined whether a difference between the signal strength of 4G of the second subscriber identity card and the signal strength of 4G of the first subscriber identity card is greater than or equal to a first preset threshold, it needs to first acquire the signal strength of 4G of the first subscriber identity card, then switch the second subscriber identity card to the master card, switch the first subscriber identity card to the slave card, and then register the second subscriber identity card to 4G, acquire the signal strength of 4G of the second subscriber identity card, and compare the signal strength with the signal strength of 4G of the first subscriber identity card acquired before.
Fig. 2 is a graph illustrating signal strength when a terminal moves between different mobile cell networks. As shown in fig. 2, the abscissa represents the direction in which the terminal moves, and the ordinate represents the signal strength. If the first user identification card is registered in the network A and the second user identification card is registered in the network B, at the moment, the first user identification card is a main card, and the second user identification card is an auxiliary card, the signal intensity of the network A and the signal intensity of the network B are detected and compared in real time in the process that the terminal moves from the network A to the network B, when the terminal reaches a point B shown in figure 2, the difference between the signal intensity of the network B and the signal intensity of the network A is detected to be larger than or equal to a first preset threshold value, the terminal automatically switches the second user identification card to be the main card, and the first user identification card is switched to be the auxiliary card.
Fig. 3 is a graph illustrating network velocity when the terminal moves between different mobile cell networks. As shown in fig. 3, the abscissa represents the direction in which the terminal moves, and the ordinate represents the mobile network rate (i.e., network rate). If the first subscriber identity card is registered in the network A and the second subscriber identity card is registered in the network B, at the moment, the first subscriber identity card is a main card and the second subscriber identity card is an auxiliary card, the network speed of the network A and the network speed of the network B are detected and compared in the process that the terminal moves from the mobile cell network A to the mobile cell network B, when the terminal reaches a point B shown in figure 3, the difference between the network speed of the network B and the network speed of the network A is detected to be larger than or equal to a first preset threshold value, the terminal automatically switches the second subscriber identity card to be the main card and the first subscriber identity card to be the auxiliary card.
For the network rate, since the real-time network rate value of the network at a certain time cannot be directly read, the network rate value needs to be calculated through statistics, that is, the network rate value is calculated according to the total flow in the preset time and the preset time, that is, the network rate is the ratio of the total flow in the preset time and the preset time.
Moreover, only the network rate of the main card can be detected, and if the network rate of the auxiliary card is detected, the main card needs to be switched to.
In an embodiment of the present invention, the first subscriber identity card or the second subscriber identity card is any one of the following:
a Subscriber Identity Module (SIM) card, a Universal Subscriber Identity Module (USIM) card, and a User Identity Module (UIM) card.
In the embodiment of the present invention, any one of the N second subscriber identity cards may be switched to the master card, and certainly, in order to avoid frequent switching of the master and slave cards, the second subscriber identity card with the largest difference between the preset parameter and the preset parameter of the first subscriber identity card may be switched to the master card.
In the embodiment of the invention, because the highest network mode supported by the main card is higher than that supported by the auxiliary card, the second subscriber identity card can be re-registered to the network corresponding to the highest network mode supported after being switched to the main card.
In the embodiment of the invention, the network modes supported by the main card comprise 2G-XG, the network modes supported by the auxiliary card comprise 2G- (X-1) G, and X is an integer greater than or equal to 2.
For example, the network modes supported by the primary card include 2G and 3G, and the network modes supported by the secondary card include 2G;
or the network modes supported by the main card comprise 2G, 3G and 4G, and the network modes supported by the auxiliary card comprise 2G and 3G;
or, the network modes supported by the primary card include 2G, 3G, 4G and 5G, and the network modes supported by the secondary card include 2G, 3G and 4G; and so on.
In another embodiment of the present invention, the method further comprises:
when the first user identification card is a main card, M second user identification cards are auxiliary cards; and when the difference between the preset parameters of the M second user identification cards and the preset parameters of the first user identification card is smaller than a first preset threshold value, keeping the first user identification card as a main card and keeping the M second user identification cards as auxiliary cards.
According to the embodiment of the invention, when the difference between the preset parameter of the second user identification card and the preset parameter of the first user identification card is greater than or equal to the first preset threshold value, the service quality of the second user identification card is considered to be higher than that of the first user identification card, and the second user identification card is switched to the main card, so that the automatic switching of the main card and the auxiliary card is realized, and the service quality of network service is improved.
In another embodiment of the present invention, before switching one of the N second subscriber identity cards to the primary card and switching the first subscriber identity card to the secondary card, the method further includes:
network searching is carried out on the frequency band supported by the terminal corresponding to the network mode supported by the second user identification card; and when the frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity card is searched, continuing to execute the step of switching one of the N second subscriber identity cards into the main card and switching the first subscriber identity card into the auxiliary card.
And when the frequency band supported by the terminal corresponding to the network mode supported by the second user identification card cannot be searched, keeping the first user identification card as a main card and M pieces of second user identification cards as auxiliary cards.
In the embodiment of the present invention, when the frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity card is searched, it is considered that the terminal has entered into the service range of the network corresponding to the network mode supported by the second subscriber identity card, and the second subscriber identity card may be switched to the master card to provide the user with the relevant service or service of the mobile network.
In the embodiment of the invention, the network search can be periodically carried out on the frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity module card; or periodically carrying out network search on a frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity module card within a preset time; or ending the network search when the frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity card is searched.
In the embodiment of the present invention, network search may be performed on a preset frequency band supported by the terminal corresponding to the network mode supported by the second subscriber identity card. The preset frequency band may be preset, and may be a whole frequency band or a partial frequency band. In order to reduce the power consumption of the terminal, a network search may be performed only on a part of the sections.
In the embodiment of the invention, network search can be respectively carried out on the frequency bands supported by the network terminal corresponding to the network modes supported by the N second subscriber identity cards; when a frequency band supported by a terminal corresponding to a network mode supported by a second user identification card is searched, switching the second user identification card searched for the network to a main card, and switching the first user identification card to a secondary card; when the frequency bands supported by the terminal corresponding to the network modes supported by two or more second user identification cards are searched, switching any one second user identification card of the searched network into a main card and switching the first user identification card into an auxiliary card; and when the frequency band supported by the terminal corresponding to the network mode supported by the N second user identification cards is not searched, keeping the first user identification card as a main card and keeping M second user identification cards as auxiliary cards.
For example, network search is performed on a frequency band supported by the terminal corresponding to the network mode supported by the 1 st second subscriber identity card; if the terminal does not search, network search is carried out on the frequency band supported by the terminal corresponding to the network mode supported by the 2 nd second subscriber identity module card; if the terminal is not searched, network searching is carried out on the frequency band supported by the terminal corresponding to the network mode supported by the 3 rd second subscriber identity module card; if the card is searched, the 3 rd second subscriber identity module card is switched to the main card, and the first subscriber identity module card is switched to the auxiliary card.
