Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a network connection method applied to a user terminal according to an embodiment of the present application, and includes the following steps S1 to S3:
s1, obtaining candidate system message blocks broadcasted by at least two candidate base stations.
Specifically, the candidate System message Block may be a System message Block 1 that can be received when the ue is located at a certain location, and optionally, the System message Block 1 may be an SIB1(System Information Block 1, the first piece of network broadcast message, which generally includes a PLMN ID and a System minimum access signal threshold, etc.).
The candidate base stations are base stations broadcasting various candidate system message blocks; and each candidate base station broadcasts a unique corresponding candidate system message block.
And S2, selecting and obtaining the target base station from the candidate base stations according to the number of the mobile network identifications in the candidate system message block.
Specifically, there are mobile network identifiers in each candidate system message block, and since there are multiple operator public base stations and a single operator-unique base station, there may be multiple situations for the number of mobile network identifiers in different candidate system message blocks, for example: 1, 2 or 3, etc.
The target base station is a base station selected from the candidate base stations according to the number of the mobile network identifications. Generally, a base station with the least number of mobile network identities or with only one mobile network identity is preferred.
Specifically, the method for selecting and obtaining the target base station may be: in a certain position, each cell obtained by scanning is determined, optionally, the same base station may correspond to multiple cells, and each cell may be a sector coverage area corresponding to one antenna corresponding to the base station, so that a user terminal in each cell may receive a candidate system message block broadcasted by the base station, and in general, one base station may correspond to three cells, the coverage area of each cell is a sector area of 120 °, and each cell may correspond to a unique corresponding cell ID, and after a resident cell is selected, the target base station for connection is determined.
And S3, carrying out network connection with the target base station.
Specifically, after the target base station is determined, the network connection with the target base station may be performed by the following method:
the user terminal can perform uplink synchronization with the target base station and establish an uplink signaling channel, namely a random access and RRC connection establishment process.
When the uplink and downlink channels between the user terminal and the target base station are good, initiating a connection request and establishing a signaling connection channel; and finally, initiating attachment (including small procedures such as authentication, encryption and the like, and if the position of the user is changed in idle time, a position updating procedure and a registration request are also carried out, and completing network connection.
Furthermore, according to the scheme in this embodiment, when the number of the mobile network identifiers is consistent with the number of the operators of the common base station, and the number of the operators in the same base station is larger and the signal stability is worse, the target base station is selected from the candidate base stations according to the number of the mobile network identifiers, and the target base station with better signal stability is selected, so that the probability of service abnormality is reduced and the user experience is improved.
As shown in fig. 2, in some embodiments, as in the foregoing network connection method, the step S2 selects a target base station from the candidate base stations according to the number of mobile network identifiers in the candidate system message block, including the following steps S211 to S214:
and S211, determining the supported network index information.
Specifically, the network index information may include information such as a frequency band supported by the user terminal and a network type. Generally, since frequency bands or network systems supported by different operators are different, a user terminal can select a base station of an operator corresponding to the user terminal by determining supported network index information.
The network index information may be a non-volatile storage parameter stored in the user terminal, or a parameter obtained after the user sets the user terminal (for example, main card selection is performed on a dual-card mobile phone) through a setting interface.
Step S212, mobile network identification in the candidate system message block is obtained.
In particular, the field of the candidate system message block for storing the mobile network identifier may include one or more mobile network identifiers. By way of example: the network index corresponding to operator a may be: 46000, 46002, the network index corresponding to operator B may be: 46011.
and S213, according to the corresponding relation between the network index information and the mobile network identifier, screening the candidate system message blocks to obtain target system message blocks corresponding to the network index information.
Specifically, since the frequency band or the network type supported by the operator can be obtained, the corresponding relationship between the network index information and the mobile network identifier can be obtained, and optionally, the corresponding relationship can be stored in the user terminal.
After the corresponding relation is determined, the mobile network identification corresponding to each network index information can be obtained firstly, then matching is carried out in all candidate system message blocks, and a target system message block is obtained by screening from all candidate system message blocks; and the target system message block has a mobile network identifier corresponding to the network index information.
And S214, selecting the target base station from the candidate base stations according to the number of the mobile network identifications in the target system message block.
Specifically, in step S213, the base station to which the user terminal can access is obtained by screening only the target system message block.
However, each target system message block may include other mobile network identifiers in addition to the mobile network identifier corresponding to the user terminal, and therefore, according to the number of the mobile network identifiers in the target system message block, a base station exclusive to a certain operator when the number of the base stations broadcasting the target system message block is determined to be 1, when the number of the base stations is greater than 1, the base stations are shared by multiple operators, and a cell covered by the target system message block is a unified cell.
Thus, the resulting target base station may be selected from the candidate base stations. The method and the device are supported by the user terminal selectively, and are not the base station shared by a plurality of operators, so that the stability of the signals can be guaranteed under the condition that the user can be enabled to be networked smoothly.
As shown in fig. 3, in some embodiments, as in the foregoing network connection method, the step S2 is to select a target base station from the candidate base stations according to the number of mobile network identifiers in the candidate system message block, and includes the following steps S221 to S223:
s221, determining the signal strength of the candidate base station.
Specifically, the signal strength of the candidate base station may be obtained by obtaining dBm values of the broadcasted signals of the respective candidate base stations.
S222, sequencing the candidate base stations from big to small according to the signal intensity to obtain sequencing information corresponding to the candidate base stations.
Specifically, when there are 3 candidate base stations A, B and C, and the signal strength corresponding to each candidate base station is X1, X2 and X3, and X1< X3< X2; the ordering information corresponding to the candidate base station a is 3; the ordering information corresponding to the candidate base station B is 1; the ranking information corresponding to the candidate base station C is 2.
Further, on the basis of the foregoing embodiment, a first candidate base station corresponding to the target system message block may also be determined in each candidate base station; and sequencing each first candidate base station from big to small according to the signal intensity to obtain sequencing information corresponding to each first candidate base station.
And S223, selecting to obtain the target base station according to the sequencing information and the number of the mobile network identifications in the candidate system message block.
Specifically, in general, the selection condition for selecting the target base station may be: and selecting the candidate base stations with the number of the mobile network identifications being 1 to obtain the target base station.
Therefore, the number of the mobile network identifiers in the candidate system message blocks broadcasted by each candidate base station is determined one by one according to the signal strength so as to select the target base station with strong signal strength and meeting the selection condition.
Further, on the basis of the foregoing embodiment, the target base station may be selected and obtained according to the ranking information and the number of mobile network identifiers in the target system message block.
In some embodiments, as in the foregoing network connection method, the step S223 selects to obtain the target base station according to the ranking information and the number of mobile network identifiers in the candidate system message block, which includes the following steps S2231 and S2232:
step S2231, according to the sorting information corresponding to each candidate base station, sequentially determining the number of the mobile network identifications in each candidate system message block until the target system message with the number of the mobile network identifications smaller than or equal to the preset value is determined in the candidate system message block.
Specifically, the preset value setting criterion may be that the stability of the signal meets a preset requirement when the number of operators coexisting in the same base station is less than or equal to the preset value.
And judging the number of the mobile network identifications in each candidate system message block according to the sequence of the sequencing information (namely, signal strength) of the candidate base stations, and if the candidate base station in the previous sequence is eliminated, sequentially selecting the candidate system message block of the next candidate base station until the target system message of which the number of the mobile network identifications is less than or equal to the preset value is obtained.
And S2232, taking the candidate base station corresponding to the target system message as the target base station.
Specifically, after the target system message is determined, since the candidate base station broadcasting the target system message is determined, the candidate base station corresponding to the target system message may be used as the target base station.
Further, when the signal strength of the candidate base station corresponding to the target system message is lower than the preset lower limit, the user experience is still poor due to too poor signal, and therefore the candidate base station with the strongest signal is selected as the target base station according to the ranking information.
In some embodiments, as in the foregoing network connection method, the step S223 selects to obtain the target base station according to the ranking information and the number of mobile network identifiers in the candidate system message block, which includes the following steps S2231:
step S2231: and when the number of the mobile network identifications in each candidate system message block is greater than a preset value, taking the candidate base station with the strongest signal intensity as a target base station according to the sequencing information.
Specifically, when the number of the mobile network identifiers in each candidate system message block is greater than the preset value, it means that each candidate base station is shared by multiple operators, and therefore, each cell corresponding to the current location of the user terminal is a unified cell.
Therefore, in this case, the signal stability cannot meet the requirement of signal stability in the preset non-unified cell (i.e. the cell covered by the broadcasted signal when one base station is exclusive to a certain operator). Therefore, the candidate base station is selected in terms of signal strength to obtain the target base station that performs best in terms of at least signal strength.
By the scheme in the embodiment, the target base station can be selected and obtained according to the signal strength under the condition that the base station meeting the requirement cannot be selected and obtained according to the signal stability, so that the best communication experience obtained by the current position of the user can be provided.
In some embodiments, as in the foregoing network connection method, the step S223 selects to obtain the target base station according to the ranking information and the number of mobile network identifiers in the candidate system message block, including the following steps S2232 to S2233:
and S2232, when the number of the mobile network identifications in each candidate system message block is greater than a preset value, calculating to obtain the weight of the candidate base station according to the number of the mobile network identifications and the signal strength according to a preset calculation strategy.
Specifically, the calculation policy may be a weighted calculation policy for performing calculation according to the number of mobile network identifiers and the signal strength.
The weight may be an evaluation score or level for evaluating each candidate base station; further, the weight may be a uniform index for evaluating each candidate base station.
For example, the formula corresponding to the calculation strategy may be P ═ a (4-x) + (1-a) (-q), where P is weight, a is the score ratio of the number of mobile network identifiers, x is the number of mobile network identifiers, and q is signal strength.
And S2233, selecting the target base station from the candidate base stations according to the weight.
Specifically, by the above method, the weight of each candidate base station can be calculated, and then the candidate base stations can be ranked according to the weight, so that the candidate base station with the highest ranking is used as the target base station.
By the method in the embodiment, the signal strength and the signal stability can be comprehensively considered, and an optimal target base station is obtained, so that the best experience is provided for a user.
In some embodiments, the network connection method as described above further includes steps P1 to P4 as follows:
and P1, determining first network index information corresponding to the main card and second network index information corresponding to the auxiliary card.
Specifically, in the prior art, a dual-card dual-standby terminal is widely used by users; the primary card may be a SIM card currently used as a network and a call, and the secondary card may be a SIM card currently used only for providing a call and not used as a network.
Generally, operators corresponding to the primary card and the secondary card are different from each other, and therefore the first network index information and the second network index information are different from each other.
And P2, screening the candidate system message blocks to obtain a first system message block corresponding to the first network index information according to the corresponding relation between the first network index information and the mobile network identifier.
Specifically, since the frequency band or the network type supported by the operator can be obtained, the corresponding relationship between the first network index information and the mobile network identifier can be obtained.
After determining the corresponding relationship between the first network index information and the mobile network identifier, the mobile network identifier corresponding to the first network index information may be obtained first, and then matching is performed in all candidate system message blocks, so as to obtain a first system message block by screening from all candidate system message blocks; and the mobile network identifier corresponding to the first network indicator information exists in the first system message block.
Step P3, according to the corresponding relation between the second network index information and the mobile network identification, screening the candidate system message blocks to obtain second system message blocks corresponding to the second network index information;
specifically, after the frequency band or the network type supported by the operator is known, the corresponding relationship between the second network index information and the mobile network identifier can be obtained.
After determining the corresponding relationship between the second network index information and the mobile network identifier, the mobile network identifier corresponding to the second network index information may be obtained first, and then matching is performed in all candidate system message blocks, so as to obtain a second system message block by screening from all candidate system message blocks; and the second system message block has a mobile network identifier corresponding to the second network indicator information.
And P4, generating a switching instruction for controlling the switching of the main card and the auxiliary card according to the first quantity of the mobile network identifications in the first system message block and the second quantity of the mobile network identifications in the second system message block.
Specifically, after the first system message block is obtained, the first number may be obtained according to the number of the mobile network identifiers in the first system message block; similarly, after the second system message block is obtained, a second number may be obtained according to the number of the mobile network identifiers in the second system message block; therefore, whether the candidate base station corresponding to the first system message block and the second system message block is a base station shared by a plurality of operators can be obtained; preferably, when a plurality of candidate system message blocks corresponding to the first network index information exist, the candidate system message block with the minimum first number is taken as the first system message block; and when a plurality of candidate system message blocks corresponding to the second network index information exist, taking the candidate system message block with the minimum second number as the second system message block.
The switching policy of the generated switching instruction for controlling the switching between the main card and the auxiliary card may be:
when the first number is larger than the second number, switching the current auxiliary card as a main card for networking; and when the first number is less than or equal to the second number, the switching between the main card and the auxiliary card is not carried out.
By the method in the embodiment, the card with the strongest signal stability can be selected as the main card by determining the operator sharing condition of the base station corresponding to the main card and the auxiliary card, so that the abnormal probability of the service of the dual-card equipment can be reduced, and the user experience can be improved.
As shown in fig. 4, an application example to which the method in the foregoing embodiment is applied is provided:
a1, starting up the UE (user terminal);
a2: selecting PLMN, after the UE is started, acquiring information such as frequency bands, modes and the like from NV (Non-Volatile storage parameters, factory-leaving important parameters integrated in the mobile phone, such as communication calibration parameters, which cannot be erased in common system formatting and the like of the mobile phone) and interface setting parameters, wherein the mode information is used for PLMN selection, and the frequency band information is sent to a physical layer; go to step A3 to search for the cell (i.e. search for candidate base station);

A5: if the cells are the only cells or all the cells are unified cells, the step A7 is switched if the cells are the only cells (namely, the signals broadcasted by only one base station can be searched at the current position) or all the cells are unified cells (namely, the first cell (the cell with the strongest signal) is selected when the cells are searched at the current position all the cells are unified cells; and the step A7 is switched to continue the uplink synchronization process).
Otherwise, reading the information broadcast by the base station of the cell, checking whether the cell is suitable for residing, checking the PLMN information in the SIB1, returning to the previous step A4 if the cell is integrated by multiple operators, selecting the secondary intensity signal cell, acquiring the SIB1 of the secondary intensity signal cell, checking the PLMN information, repeating the steps until the non-integrated cell is acquired, and continuing the A7 uplink synchronization process;
in addition, the process also includes cell selection rule checking to determine whether the cell is a suitable cell, if the signal meets the requirement of a single operator cell in a6, the cell is allowed to reside and transferred to a7, otherwise, the cell cannot be registered, and another cell is reselected.
A6: whether the cell is a single operator cell or not, whether the PLMN information in the SIB1 broadcast only has a single PLMN ID or not is checked, if so, the cell is a single operator cell (the base station is exclusive to a certain operator) and is turned to A7, otherwise, the next cell is selected by returning to A4.
A7: uplink synchronization, after selecting a cell, the UE performs uplink synchronization and establishes an uplink signaling channel, that is: random access and RRC connection establishment procedures.
