Under eUICC scene, eUICC and SM (SubscriptionManager: signing administrative unit) is needed to carry out flow process mutual, and then realize the switching of Profile, as shown in Figure 1, for the Profile activation process figure in GSMA (GlobalSystemforMobileCommunicationAssociation: global system for mobile communications association) eSIM (embeddedSubscriberIdentityModule: embedded user identification module) standard, specifically comprise the following steps:

Step S101:MNO sends Profile activation request to SM-SR (SubscriptionManager-SecurelyRouting: signing administrative unit-Security routing), EID (eUICCID: universal embedded integrated circuit card identity is carried in Profile activation request, the unique identification of eUICC) and ICCID (IntegratedCircuitCardIdentity: integrated circuit card identity is the mark of Profile on eUICC).

Step S102:SM-SR according to EID and ICCID, on target eUICC current be in state of activation Profile and Profile to be activated carry out the detection of POL2 (POLicy2: strategy 2 is the strategies be positioned on SM-SR).

Step S103: if policy conflict (namely not meeting the policing rule in POL2) detected in step s 102, SM-SR sends error notification to MNO.

Step S104: pass through if the strategy of step S102 detects, carry out two-way authentication between SM-SR and eUICC.

Step S105: after two-way authentication, SM-SR sends request to eUICC the request message that this eUICC activates target P rofile, the ISD-P-AID (IssuerSecurityDomain-Profile-ApplicationIdentity: issuer security domain-configuration file-application identities is the mark of container eUICC depositing Profile) of target P rofile is carried in this request message.

The strategy that the Profile that step S106:eUICC is in state of activation to current and target P rofile to be activated carries out POL1 (POLicy1: strategy 1, is the strategy be positioned on eUICC, associates with each specific Profile) detects.

Step S107: if policy conflict detected in step s 106, eUICC sends error notification by SM-SR to MNO, prompting POL1 conflict.

Step S108: if policy conflict do not detected in step S106, makes current Profile be in deactivation status, makes target P rofile be in state of activation.

Step S109:eUICC sends Profile activation confirmation message to SM-SR.

Step S110:SM-SR upgrades the state information of relevant Profile in EIS (EuiccInformationSet:eUICC information set).

Step S111:SM-SR sends Profile activation result to MNO.

In the prior art, Profile is being carried out to the detection of POL2 and POL1 strategy by afterwards, just carry out Profile switching, and likely the signal strength signal intensity of target P rofile can not satisfy the demands, in this case, may not need to carry out Profile switching, so there is Profile in prior art to switch reasonable not and effective technical problem.

Embodiment

Not accurate enough technical problem is switched for Profile in prior art, in the technical scheme that the embodiment of the present application proposes here, provide a kind of Profile changing method, comprise: universal embedded integrated circuit card eUICC receives the Profile activation request that signing administrative unit-Security routing SM-SR sends, first mark of target P rofile is carried in one Profile activation request, or eUICC sends the 2nd Profile activation request of second mark of carrying target P rofile to SM-SR, and receive the activation response message that SM-SR returns based on the 2nd Profile activation request, eUICC indicates the subscriber equipment at eUICC place to carry out input, and obtains the signal detecting result of mobile communications network corresponding to target P rofile from subscriber equipment, eUICC, according to switchover policy information and signal detecting result, determines whether to carry out Profile switching.Due to before carrying out Profile switching, need signal detecting result and the switchover policy information of considering the mobile communications network that target P rofile is corresponding, so reach Profile to switch more reasonable and effective technique effect.

Below in conjunction with each accompanying drawing, the main of the embodiment of the present application technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.

First aspect, the embodiment of the present invention provides a kind of Profile changing method, please refer to Fig. 2, specifically comprises the following steps:

Step S201: the Profile activation request that the signing administrative unit-Security routing SM-SR of universal embedded integrated circuit card eUICC reception sends, carries first mark of target P rofile in a Profile activation request; Or eUICC sends the 2nd Profile activation request of second mark of carrying target P rofile to SM-SR, and receives the activation response message that SM-SR returns based on the 2nd Profile activation request;

Step S202:eUICC indicates the subscriber equipment at eUICC place to carry out input, to obtain the signal detecting result of mobile communications network corresponding to target P rofile;

Step S203:eUICC, according to switchover policy information and signal detecting result, determines whether to carry out Profile switching.

In step S201, the first mark and the second mark, all for identifying target P rofile, adopt different marks for the equipment difference sending Profile activation request.When sending a Profile activation request to initiate Profile switching by SM-SR, the first mark that a Profile activation request is carried is specifically as follows: the ISD-P-AID of target P rofile; When sending the 2nd Profile activation request to initiate Profile switching by eUICC, the second mark that the 2nd Profile activation request is carried is specifically as follows: EID and ICCID of target P rofile.

In step S201, the initiator of the one Profile activation request is MNO, so first MNO sends a Profile activation request directly to SM-SR, or send a Profile activation request by SM-DP (SubscriptionManager-DataPreparation: signing administrative unit-data encasement) to SM-SR, in a Profile activation request, carry first mark etc. of eUICC mark, target P rofile.

Then a Profile activation request is sent to eUICC by SM-SR, and eUICC, after receiving a Profile activation request, just starts Profile handoff procedure.In this case, the first mark is generally: the ISD-P-AID of target P rofile.

In step S201, the initiator of the 2nd Profile activation request is eUICC, is so first that on eUICC, Profile switching is triggered, includes but not limited to following situation: 1) user initiates Profile handover request by subscriber equipment Device; 2) trigger condition (can based on time, position etc.) of the upper setting of eUICC meets; 3) other situations;

After Profile switching on eUICC is triggered, eUICC sends the 2nd Profile activation request comprising the second mark to SM-SR, after SM-SR receives the 2nd Profile activation request, send to eUICC and activate response message, eUICC, after receiving activation response message, just starts Profile handoff procedure.In this case, the second mark is generally: EID and ICCID of target P rofile.

In step S202, the subscriber equipment at eUICC place is such as the subscriber equipment embedded by eUICC.

In step S202, eUICC indicates the subscriber equipment at eUICC place to carry out input can be divided into multiple situation again, and two kinds of enumerating below are wherein introduced, and certainly, in specific implementation process, are not limited to following two kinds of situations.

As a kind of possible implementation, eUICC is receiving a Profile activation request or after receiving activation response message, is directly indicating the subscriber equipment at eUICC place to carry out input.

As the implementation that another kind is possible, input strategy is carried in one Profile activation request, eUICC is after receiving a Profile activation request, input strategy is read from Profile activation request, if when input strategy shows to need subscriber equipment to carry out input, eUICC then indicates the subscriber equipment at eUICC place to carry out input.

In this case, if input strategy shows not need to carry out input, then show unconditionally to carry out Profile switching, so in this case, do not need to carry out input by subscriber equipment, but directly carry out Profile switching.

Due in such scheme, need first to determine whether to need to carry out input, so prevent unnecessary input, thus reach the technique effect reducing subscriber equipment detection burden.

As further preferred embodiment, in step S202, eUICC indicates the subscriber equipment at eUICC place to carry out input, please refer to Fig. 3, specifically comprises:

Step S301:eUICC obtains input number of times from target P rofile and public land mobile network PLMN corresponding to target P rofile identifies;

Step S302:eUICC sends the indication information carrying input number of times and PLMN mark to subscriber equipment, indication information is used to indicate the signal strength signal intensity that subscriber equipment detects PLMN.

In specific implementation process, input number of times and PLMN (PublicLandMobileNetwork: public land mobile network) mark can be obtained according to first mark of target P rofile or the second mark from target P rofile.

In specific implementation process, not identical for its input number of times of different target P rofile, such as: for the subscriber equipment be often kept in motion, because its signal is also unstable, so the input number of times of the target P rofile of its correspondence is more, and for the subscriber equipment often remained static, because its signal is more stable, so the input number of times of the target P rofile of its correspondence is less, so different input number of times can be stored therein for different target P rofile, subscriber equipment can detect the signal strength signal intensity of PLMN according to the input number of times in target P rofile.Further, because the input number of times stored in target P rofile is arranged according to the frequent status of target P rofile, the current state of target P rofile can be different with it, therefore subscriber equipment can also carry out input according to the current state of the input number of times in target P rofile and subscriber equipment, such as: if input number of times is 3 show that subscriber equipment often remains static in target P rofile, and the current state of subscriber equipment is motion state, so subscriber equipment then can increase by a preset signals detection number of times on the basis of input number of times, such as increase by 2 times, otherwise, if input number of times is 6 show that subscriber equipment is often kept in motion in target P rofile, and the current state of subscriber equipment is inactive state, so subscriber equipment then can reduce by a preset signals detection number of times on the basis of input number of times, such as, reduce 2 times.In this case, for subscriber equipment or the frequent static and current subscriber equipment being in motion of motion, the detection of its signal strength signal intensity is more accurate; For static subscriber equipment or take regular exercise and be currently in static subscriber equipment, the number of times of detection can be reduced, reduce and detect burden, thus reach the technique effect reducing while ensureing signal strength detection precision and detect burden.

And in specific implementation process, subscriber equipment can obtain the signal strength signal intensity of PLMN in several ways, the two kinds of modes enumerated below are wherein introduced, and certainly, in specific implementation process, are not limited to following two kinds of modes.

As a kind of possible implementation, the signal of subscriber equipment to whole frequency range detects, and obtains the signal strength signal intensity of each frequency range, and obtains the signal strength signal intensity of PLMN from the signal strength signal intensity of each frequency range.

For example, after supposing that whole frequency range detects, signal strength signal intensity as shown in table 1 is obtained:

Frequency range	a1～a2	b1～b2	c1～c2
				Signal strength signal intensity	50dBm	0dBm	5dBm

Table 1

Wherein, the frequency range of PLMN mark correspondence is a1 ~ a2, and then determines that the signal strength signal intensity of PLMN is: 50dBm.Certainly, above-mentioned data are only a citing, not as restriction.

As the implementation that another kind is possible, subscriber equipment detects the signal strength signal intensity that PLMN identifies corresponding frequency band, obtains the signal strength signal intensity of PLMN.

For example, if the frequency range of PLMN mark correspondence is: a1 ~ a2, so only detect the signal strength signal intensity that a1 ~ a2 frequency range is corresponding, in this case, owing to only needing the signal strength signal intensity of test section frequency range, reduce so reach the technique effect that subscriber equipment detects burden.

In specific implementation process, in step S203, switchover policy information can be obtained by number of ways, introduces two kinds of acquisition patterns wherein below, certainly, in specific implementation process, is not limited to following two kinds of modes.

As a kind of possible implementation, switchover policy information is carried in a Profile activation request, is sent to eUICC by SM-SR, in this case, usually triggers Profile handoff procedure by MNO.

As the implementation that another kind is possible, switchover policy information is updated to eUICC by MNO, and then after triggering Profile handoff procedure, directly can obtain switchover policy information at eUICC, in this case, usually both Profile handoff procedure can be triggered by MNO, also Profile handoff procedure can be triggered by eUICC.

In specific implementation process, predetermined threshold value, preset times and the first switch logic can be comprised in switchover policy information in step S203, wherein, first switch logic can be: if the number of times that the signal strength signal intensity of PLMN exceedes predetermined threshold value in input number of times is greater than preset times, then carry out Profile switching, otherwise refusal Profile switches.

For example, if input number of times is 10 times, wherein preset times is 7 times, and predetermined threshold value is 10dBm, detects that signal strength signal intensity is more than 10dBm 8 times, 9 times if so had, then show that signal strength signal intensity is better, then determine to carry out Profile switching; And if only have and detect that signal strength signal intensity is more than 10dBm for 2 times, 3 times, then refuse Profile and switch.

In this case, ensure that after carrying out Profile switching, use the high reliability of the normal access network of target P rofile.

In addition, also can only comprise the second switch logic in the switchover policy information in step S203, the second switch logic is specifically as follows: if the signal of PLMN detected, carry out Profile switching, otherwise refusal Profile switches.

Specifically, as long as namely detected that signal just carries out Profile switching, there is no signal if detected, do not carried out Profile switching.

Do not need this situation of carrying out signal strength detection, the reliability requirement that can meet normal access network after switching for Profile is not high, but does not allow the requirement switching the rear subscriber equipment of no signal completely.

In specific implementation process, in step S203, do not allow to switch Profile, eUICC if be judged to be and can send error notification to SM-SR; Carry out Profile switching if be defined as, then can carry out Profile switching, Profile switching comprises the following steps: eUICC by the current Profile deexcitation being in state of activation, and activates target P rofile.

As further preferred embodiment, carry out Profile switching if be defined as, and Profile handoff failure, eUICC can reactivate the Profile used before not carrying out Profile switching.

In the embodiment of the present application, if target P rofile activates unsuccessful words, Fall-Back (i.e. rollback) mechanism will be adopted, specifically the Profile with Fall-Back attribute is namely activated, should with the Profile normally PP (ProvisioningProfile: configuration file) of Fall-Back attribute, this file is the class Profile for Profile configuration/management, do not use voice or the data service of operator by PP, but eUICC can be made to be connected to SM-SR.So the switching of Fall-Back mechanism can be adopted back into the Profile used before row Profile switching when target P rofile activates unsuccessful by the scheme in the embodiment of the present invention, even if Profile handoff failure can be ensured, subscriber equipment also can be allowed to use original OP access carrier network.

As further preferred embodiment, the first key can also be carried in Profile activation request, namely the first key that SM-SR and eUICC consults generation is carried in a Profile activation request or the 2nd Profile activation request, wherein, the second key encrypting a Profile activation request or encryption the 2nd Profile activation request is different from the first key, and the first key and the second key are consulted to generate by SM-SR and eUICC; When carrying the first key in a Profile activation request or the 2nd Profile activation request, the Profile changing method that the embodiment of the present application provides also comprises:

Carry out Profile switching if be defined as, and Profile handover success, then eUICC sends Profile activation confirmation message with the first secret key encryption to SM-SR.

In specific implementation process, receive the Profile activation request of SM-SR transmission at eUICC before, can consult between SM-SR and eUICC to generate key, its process consulting to generate key is such as follows: SM-SR dynamically generates a pair PKI A and key B (asymmetric encryption), then PKI A is sent to eUICC, eUICC oneself dynamically generates symmetric key C and D (i.e. the second key and the first key), then send to SM-SR after being encrypted by C and D by PKI A, SM-SR obtains symmetric key C and D by key B to C and the D deciphering after encryption.After this SM-SR by symmetric key C encrypt to eUICC send a Profile activation request or eUICC by symmetric key C encrypt to SM-SR send the 2nd Profile activation request, eUICC after Profile handover success by symmetric key D encrypt to SM-SR send Profile activation confirmation message.

Be such as: the second key and the first key of consulting generation between SM-SR and eUICC are respectively: keyset and keyset-a, a Profile activation request so in step S201 received by eUICC uses keyset encryption, then keyset-a is carried in Profile activation request, eUICC then encrypts Profile activation confirmation message by keyset-a, then sends the Profile activation confirmation message of being encrypted by keyset-a to SM-SR.

Due in such scheme, do not need again to hold consultation generation key after Profile switches, so decrease the interaction times between eUICC and SM-SR, improve the efficiency that Profile switches.

Introduce Profile changing method, signal detecting method, eUICC, subscriber equipment and the SM-SR in the present invention below by way of several specific embodiment, the following examples mainly describe the reciprocal process of eUICC, subscriber equipment and SM-SR.It should be noted that, the embodiment in the present invention only for explaining the present invention, and can not be used for limiting the present invention.All meet the embodiment of inventive concept all within protection scope of the present invention, and those skilled in the art know naturally should how thought according to the present invention be out of shape.

Embodiment one

In the present embodiment, with the Profile switching flow of being initiated by MNO to introduce Profile changing method in the embodiment of the present invention and signal detecting method, please refer to Figure 12, specifically comprise the following steps:

Step S1201:MNO sends Profile activation request to SM-SR, wherein, MNO can send Profile activation request directly to SM-SR, also can send Profile activation request by SM-DP to SM-SR, in Profile activation request, carry ICCID and the Profile switchover policy of EID, target P rofile.

Step S1202:SM-SR according to EID and ICCID, on target eUICC current be in state of activation Profile and the Profile to be activated strategy that carries out POL2 detect, POL2 also i.e. POLicy2, represents the strategy be positioned on SM-SR.

It is one or more that the tactful Detection of content of POL2 comprises in following Detection of content:

1) disablednotallowed (not allowing deexcitation);

2) deletednotallowed (not allowing to delete);

3) the maximumnumberofprofilesintheeUICC maximum quantity of Profile (on the eUICC card);

4) theentitytonotifyofprofilerelatedoperation (needing to notify which entity to the correlation results of profile);

5) other.

Step S1203: if policy conflict detected in step S1202, such as: detect that target P rofile does not support to activate by POL2, so SM-SR sends error notification to MNO, also can send error notification by SM-DP to MNO.

Step S1204a: pass through if the POL2 strategy of step S1202 detects, use PKI (PublicKeyInfrastructure: PKIX) certificate or symmetric key to carry out two-way authentication between SM-SR and eUICC, say below and introduce two kinds of authentication modes respectively.

1) if use PKI certificate, first be the certification of eUICC to SM-SR, SM-SR sends certificate and the signature of SM-SR to eUICC, uses the public key verifications SM-SR certificate of CA (CertificateAuthority: digital center management organization) legal after eUICC receives; From certificate, obtain the PKI of SM-SR, utilize the signature of public key verifications SM-SR legal, be verified, then SM-SR is legal SM-SR entity; Then be the certification of SM-SR to eUICC, similar with said process;

2) if use symmetric key, the certificate that both sides use the symmetric key encryption/deciphering the other side appointed in advance to send, the legitimacy of identity verification.

Consult between step S1204b:SM-SR and eUICC to generate key, for encryption and the integrity protection of command transfer in step S1205, concrete generation cipher key processes is as follows:

SM-SR dynamically generates a pair PKI A and key B (asymmetric encryption), then PKI A is sent to eUICC, eUICC oneself dynamically generates a symmetric key C and key D (i.e. the second key and the first key), then by PKI A-key C and D, send to SM-SR after encryption, SM-SR obtains symmetric key C and D by key B to C and the D deciphering after encryption.After this both sides are by symmetric key C enciphered data.Here the ciphering key generated and D, be called keyset and keyset-a.

Step S1205:SM-SR sends the Profile activation request through keyset encryption to eUICC, carries ISD-P-AID, key keyset-a and Profile switchover policy information in request message;

Here Profile switchover policy packets of information is containing the one in following switchover policy information:

If the number of times that 1. signal strength signal intensity of PLMN exceedes predetermined threshold value is greater than preset times, then carry out Profile switching, otherwise refusal Profile switches.

If the signal of PLMN 2. detected, carry out Profile switching, otherwise refusal Profile switches.

The strategy that the Profile that step S1206:eUICC is in state of activation to current and target P rofile to be activated carries out POL1 detects, and POL1 also i.e. POLicy1, refers to the strategy be positioned on eUICC, associate with each specific Profile.

It is one or more that the tactful Detection of content of POL1 comprises in following Detection of content:

1) disablednotallowed (not allowing deexcitation);

2) deletednotallowed (not allowing to delete);

5) other.

Step S1207: if POL1 policy conflict detected in step S1206, eUICC send the error notification through keyset encryption to SM-SR.

Step S1208: if the POL1 strategy of step S1206 detects pass through, eUICC extracts PLMN information and signal detecting method from target P rofile, and signal detecting method is such as: input number of times.

Step S1209:eUICC sends input request to subscriber equipment, carries PLMN information and signal detecting method.

Step S1210: the state information (such as: velocity information etc.) of subscriber equipment integrated signal detection method and subscriber equipment, carry out signal strength detection, obtain the signal strength signal intensity of PLMN corresponding to the identification information of target P rofile, its detection mode is such as: after full range scanning, obtain the strength information of each frequency, then from the strength information of each frequency, obtain signal strength signal intensity corresponding to PLMN information.

Step S1211: subscriber equipment returns the signal strength signal intensity of PLMN to eUICC, this signal strength signal intensity can be divided into signal fabulous, jitter and no signal three kinds.

Such as, signal is fabulous to be referred to: the signal strength signal intensity of repeated detection PLMN, if the number of times wherein exceeding preset strength is greater than threshold value, then represent that signal is fabulous, suppose that detection number of times is 10 times, threshold value is 8, there is the signal strength signal intensity of 9 times to exceed preset signal strength in so detecting at 10 times, then show that signal is fabulous; Jitter refers to: the signal strength signal intensity of repeated detection PLMN, the signal strength signal intensity of the PLMN detected is greater than 0, but the number of times being above preset signal strength is less than threshold value, same hypothesis detection number of times is 10 times, threshold value is 8, if so detect that the signal strength signal intensity of 3,1 times exceedes preset signal strength, then show jitter; No signal then refers to when repeated detection, the signal of PLMN do not detected.

Step S1212:eUICC, according to Profile switchover policy and signal detecting result, judges whether to carry out Profile switching;

Suppose that Profile switchover policy is: if the number of times that the signal strength signal intensity of PLMN exceedes predetermined threshold value is greater than preset times, then carry out Profile switching, otherwise refusal Profile switch, so can signal detecting result be signal fabulous time, just carry out Profile switching;

If Profile switchover policy is: if the signal of PLMN detected, carry out Profile switching, otherwise refusal Profile switches, and so fabulous at signal or swinging of signal timing, can carry out Profile switching.

Step S1213: if judge in step S1212 that not allowing to switch Profile, eUICC sends error notification to SM-SR;

Step S1214: if judge in step S1212 to allow to switch Profile, eUICC by the current Profile deexcitation being in state of activation, and activate target P rofile;

Illustrate: if in step S1214 on eUICC target P rofile activate and occur abnormal, eUICC will reactivate original Profile.

Step S1215: if target P rofile activates successfully, eUICC send Profile activation confirmation message to SM-SR, and this activation confirmation message uses key keyset-a encryption to ensure confidentiality.

Step S1216:SM-SR upgrades the state information of relevant Profile in EIS;

Step S1217:SM-SR sends the order of Profile activation result to MNO, carries EID, ICCID etc., to inform the activation result of Profile to MNO.

Step S1307:eUICC sends input request to subscriber equipment, carries PLMN information and signal detecting method;

Step S1308: the state information of subscriber equipment integrated signal detection method and subscriber equipment, detects and obtains the PLMN signal strength signal intensity corresponding with the identification information of target P rofile;

Step S1309: subscriber equipment is to eUICC inverse signal testing result, and this result can at least be divided into signal fabulous, jitter and no signal three kinds;

Step S1310:eUICC, according to Profile switchover policy information and signal pre-detection result, judges whether to carry out Profile switching;

Illustrate: Profile switchover policy includes but not limited to: 1) only switch when signal is fabulous; 2) as long as there is signal just to switch; 3) even if no signal also switches; 4) other situations.

Step S1311: if judge in step S1310 that not allowing to switch Profile, eUICC sends error notification to SM-SR;

Step S1312: if judge in step S1310 to allow to switch Profile, eUICC by the current Profile deexcitation being in state of activation, and activate target P rofile;

Illustrate: if the target P rofile in step S1312 on eUICC activates occur that eUICC will reactivate original Profile extremely.
