Above-mentioned all optional technical schemes, all can be according to the alternative embodiment arbitrarily combining to form the disclosure, and the disclosure is real
Apply example this is no longer repeated one by one.
Fig. 2 is another kind of method for switching network flow chart that the embodiment of the present disclosure provides, and this method for switching network is applied to
In the terminal of double card single-pass, this terminal is provided with the first SIM and the second SIM, as shown in Fig. 2 this method for switching network
Comprise the following steps.
In step 201, when detect the second SIM is switched to by the first SIM when, will storage TAC banned list
Empty, this TAC banned list is used for storage and forbids carrying out cell TAC of network connection.
In the disclosed embodiments, terminal is provided with two SIMs, for convenience of description, terminal is currently made
SIM as the first SIM, using the SIM being used after network switching as the second SIM.In addition, terminal is using
During one SIM and other-end carry out information exchange, terminal is to be realized with other-end by the cell being presently in
Information exchange, and each cell has oneself corresponding TAC.If terminal network connection in the cell being presently in lost
Lose, the TAC of this cell can be stored in TAC banned list for terminal, it is to avoid terminal carries out net in same cell repeated attempt
Network connects.That is, in terminal during using the first SIM, terminal is according to connecting the corresponding mobile network of the first SIM
Connection, the TAC banned list before the current time that is stored with.Wherein, this mobile network can be LTE network, LTE net
Network is the evolvement network of existing 3G network, and LTE network is widely used because of its efficient information exchange speed.
Because the cell in this TAC banned list is that terminal is added during using the first SIM, when terminal is cut
When shifting to the second SIM, when the cell that terminal is presently in belongs to the cell in above-mentioned TAC banned list, this cell corresponds to
MME (Mobility Management Entity, mobile management entity) may allow this terminal access this cell, but by
Belong to the cell in TAC banned list in this cell, lead to terminal cannot access this cell by the second SIM.Therefore, at this
In open embodiment, when terminal switches to the second SIM by the first SIM, in order that terminal can smoothly connect to second
The corresponding mobile network of SIM, when terminal detects and is switched to the second SIM by the first SIM, terminal can be when will be current
Between before storage TAC banned list empty.
In addition, in the disclosed embodiments, this method for switching network is applied in the terminal of double card single-pass, for double card list
Logical terminal, mainly has manual switching and the two kinds of network switching modes that automatically switch at present.Manual switching, namely only work as terminal
When the instruction for network switching is detected, terminal just can switch to the second SIM by the first SIM, for example, has in the terminal
" network switching " option, when user is somebody's turn to do " network switching " option by predetermined registration operation triggering, terminal will detect for network
The instruction of switching, then switches to the second SIM by the first SIM.Wherein, predetermined registration operation can be clicking operation, slip behaviour
Make etc..Automatically switch, namely in the terminal control module be installed, this control module can ceaselessly two mobile networks it
Between switch, and automatically search for network, when this control module switches between the two networks, terminal may also detect that this network
Handover operation.Therefore, no matter terminal manually switches or automatically switches is realized network switching, terminal may detect that by
First SIM is switched to the operation of the second SIM, then execution step 201.
In step 202., determine the identity information of the second SIM.
After the TAC banned list storing before terminal is by current time empties, terminal can be by network by a SIM
Card switches to the second SIM, then accesses the corresponding mobile network of the second SIM.Access the corresponding shifting of the second SIM in terminal
During dynamic network, the AUC in MME needs the identity information of this second SIM to be verified, to determine whether
Terminal is allowed to access the corresponding mobile network of this second SIM, therefore, terminal needs first to determine the identity letter of this second SIM
Breath.
Wherein, the identity information of the second SIM is used for this second SIM of unique mark, in the authentication of the 2nd SIM and MME
In be previously stored with the heart the identity information of this second SIM, the identity information of this second SIM includes IMSI
(International Mobile Subscriber Identity, international mobile subscriber identity) and Ki (Key
Identifier, mobile phone identification key) etc..IMSI is used for unique identification mobile subscriber namely SIM, and Ki is SIM and operation
Between business encryption data transmission key, and IMSI and Ki use cooperatively can be used to verify the identity information of this second SIM.
In step 203, the identity information according to the second SIM, current connected mobile network is switched to second
The corresponding mobile network of SIM, to realize network switching.
In the disclosed embodiments, terminal, can be by the body of the second SIM after the identity information determining the second SIM
Part information is sent to AUC, when AUC receives the identity information of this second SIM, to this second SIM
Identity information is verified, if the verification passes, then allows this terminal to access this second SIM by the second SIM corresponding
Mobile network, realizes terminal and switches to the corresponding mobile network of the second SIM by the corresponding mobile network of the first SIM.
In a kind of possible implementation, the realization that AUC is verified to the identity information of this second SIM
Process can be：When AUC receives the identity information of this second SIM, by this second SIM identity information bag
IMSI and Ki including, calculates SRES (Signed Response, sign response), if the SRES that calculates of AUC and
The SRES that second SIM is calculated by IMSI with Ki is identical, then authenticate successfully, shows that terminal can access this second SIM
Corresponding mobile network.Otherwise authenticate unsuccessful, namely terminal does not have authority to access the corresponding mobile network of this second SIM.
Alternatively, in the disclosed embodiments, after terminal passes through the second SIM access to mobile network, namely at end
During end carries out information exchange by the second SIM and other-end, terminal can correspond to according to accessing this second SIM
Mobile network situation, the TAC banned list after emptying is updated.TAC banned list after terminal-pair empties is carried out
Renewal can be realized by step 204.
In step 204, determine the cell of network connection failure, and the TAC of the cell of this network connection failure is added
In TAC banned list to after empty, to update this TAC banned list.
After terminal accesses the corresponding mobile network of the second SIM, terminal is currently likely to occur connection network failure feelings
Condition, now in order to avoid terminal repeated attempt accesses this cell, the TAC of the cell of network connection failure can be added to by terminal
So that terminal cannot access this network connection failure cell by the second SIM in TAC banned list after emptying.
Wherein, terminal determine network connection failure cell can by following two possible by way of realize.
The first possible mode, occurs interrupting with the corresponding mobile network of this second SIM when terminal is current, namely net
During network connection failure, determine connection failure number of times, when connection failure number of times exceedes preset times threshold value, little by be presently in
Area is defined as the cell of network connection failure.
It should be noted that when network connection failure is detected, if directly the TAC of the cell being presently in is added
To in TAC banned list, terminal will be unable to be linked into this cell again, especially, when the network of the cell that this is presently in
It is that of short duration appearance is abnormal, the TAC of the cell being now presently in this is added in TAC banned list, leads to the net of this cell
After network recovers normal, terminal also cannot access the cell that this is presently in.Therefore, in the disclosed embodiments, when terminal detects
During to network connection failure, record connection failure number of times, and start timing, when timing time reaches, re-start network even
Connecing, if re-start network connection still failed, updating connection failure number of times, repeat to start timing, circulation executes above-mentioned behaviour
Make, until terminal accesses the corresponding mobile network of this second SIM, or connection failure number of times exceedes preset times threshold value.When even
When connecing the frequency of failure and exceeding preset times threshold value, show that exception persistently in the network of the cell being presently in, now terminal can
So that the cell being presently in be defined as the cell of network connection failure, and the TAC of the cell that this is presently in is added to clearly
In TAC banned list after sky, it is to avoid terminal repeated attempt accesses the cell that this is presently in.
Wherein, timing time is the time pre-setting in terminal, and this timing time can be 5s, 10s or 15s etc..In advance
If frequency threshold value is the number of times pre-setting in terminal, this preset times threshold value can be inferior for 5 times, 10 times or 20.
For example, timing time is 5s, and preset times threshold value is 5 times, when terminal detects network connection failure, starts to count
When, and record connection failure number of times for 1 time, when timing time 5s reaches, re-start network connection, circulation executes, if
More than 5 times, terminal, still without accessing this cell of being presently in, shows the network of this cell being presently in connection failure number of times
Persistently occur abnormal, therefore, the cell that this is presently in can be defined as the cell of network connection failure by terminal.
The possible mode of second, when the position being presently in changes, detection is presently in the signal energy of cell
Measure and be presently in the signal energy of the adjacent cell of cell, when the signal energy of adjacent cell exceedes the signal energy being presently in cell
During amount, re-start network registry, to access this adjacent cell.When receiving network registry failed message, will be true for this adjacent cell
It is set to the cell of network connection failure.
It should be noted that terminal is after by the second SIM access to mobile network, only terminal is in certain cell
Network coverage when, this terminal just can receive the system message of this cell.Network coverage due to neighbor cell
There is common factor, therefore, terminal, when current location, except receiving the system message of the cell being presently in, can also receive
The system message of other cells, this other cell namely adjacent cell.
In the possible mode of second, when the position being presently in changes, terminal receives and is presently in cell
System message and be presently in cell adjacent cell system message, according to the system message being presently in cell and current institute
The system message of the adjacent cell of place's cell, the letter determining the signal energy being presently in cell and being presently in the adjacent cell of cell
Number energy, then judges whether to need to carry out location updating.That is, being presently in cell when the signal energy of adjacent cell exceedes
During signal energy, terminal re-starts network registry, to access this adjacent cell.
Wherein, terminal re-starts network registry, that is, terminal sends the 2nd SIM to the corresponding MME of the second SIM
The identity information of card and the TAC of this adjacent cell, when MME receives the TAC of the identity information of the second SIM and this adjacent cell,
Judge the TAC of this adjacent cell whether belong to forbid this second SIM access cell TAC, when this adjacent cell be not belonging to prohibit
Stop the access of this second SIM the TAC of cell when, update the TAC of the residing cell of this second SIM, that is, by this adjacent cell
The TAC of cell that is presently in as this terminal of TAC so that MME can follow the tracks of this terminal, and send corresponding industry to this terminal
Business.When MME update this second SIM be presently in cell TAC when, determine this terminal can by second SIM access
This adjacent cell, then sends network registry success message to terminal.
Correspondingly, when the TAC that MME determines this adjacent cell belongs to the TAC of the cell forbidding that this second SIM accesses, really
This terminal fixed does not have authority to access this adjacent cell by the second SIM, sends network registry failed message to terminal.When terminal connects
When receiving network registry failed message, this adjacent cell is defined as the cell of network connection failure, and the TAC of this adjacent cell is added
It is added in TAC banned list, it is to avoid terminal iterates through the second SIM and accesses this adjacent cell
Wherein, the system message of the system message being presently in cell and the adjacent cell being presently in cell includes accordingly little
PLMN belonging to the TAC in area, respective cell ((Public Land Mobile Network, public land mobile network) and
The information such as the signal energy of respective cell.PLMN is used for distinguishing different operators, is presently in cell when terminal receives
During the system message of adjacent cell, can first judge whether the PLMN belonging to this adjacent cell belongs to the PLMN of terminal unit contractual, work as adjacent cell
When affiliated PLMN is the PLMN of terminal unit contractual, terminal just continues executing with the need of the operation carrying out location updating.Especially,
When PLMN belonging to when cell is not the PLMN of terminal unit contractual, terminal can not possibly access this adjacent cell, namely is not carried out
The operation of location updating.
In the disclosed embodiments by the mobile network being connected is being switched to the corresponding mobile network of the second SIM
