## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of International Application No. PCT/CN2013/086644, filed on Nov. 6, 2013, which claims priority to Chinese Patent Application No. 201210437614.7, filed on Nov. 6, 2012, both of which are hereby incorporated by reference in their entireties.


TECHNICAL FIELD
Embodiments of the present invention relate to communications technologies, and in particular, to a subscription transfer method, apparatus, and system.
BACKGROUND
An embedded universal integrated circuit card (eUICC) is a non-pluggable smart card that can be used in a user equipment (UE). A greatest difference from a conventional universal integrated circuit card (UICC) is that an eUICC is fixed in a UE and cannot be replaced freely. Software functions of the two cards are basically consistent. The eUICC has an advantage of a small volume, which saves space of UE components and provides good shockproof performance.
With respect to a conventional UICC, when changing a UE, a user may move the UICC from an old UE to a new UE and reserve a subscription on the UICC at the user's discretion. After the UE is changed, the user may still use user data on the UICC card, and thereby can access an operator network. However, with respect to a UE using an eUICC, when the UE is changed due to reasons such as a fault or a user requirement, the prior art cannot transfer an eUICC subscription between UEs that use the eUICC, and therefore, it is inconvenient and inflexible for the user to change the UE.

DETAILED DESCRIPTION
To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
FIG. 1 is a flowchart of Embodiment 1 of a subscription transfer method according to the present invention. As shown in FIG. 1, the subscription transfer method in this embodiment may include the following steps.
S101. Receive a subscription transfer request message sent by a first UE or a second UE, where the first UE is a target UE to which an eUICC subscription is transferred, and the second UE is a source UE from which the eUICC subscription is transferred.
For example, if the first UE initiates subscription transfer, the subscription transfer request message may carry an embedded universal integrated circuit card identity (eUICC identity or eID for short) and/or an international mobile equipment identity (IMEI) of the first UE, an address or identity of an SP device, information of the second UE, and a subscription transfer indication, where the SP may also be an MNO; if the second UE initiates subscription transfer, the subscription transfer request message may carry an eID and/or IMEI of the second UE, an address or identity of an SP device, information of the first UE, and a subscription transfer indication. The SP device may obtain the eID and/or IMEI of the first UE or the eID and/or IMEI of the second UE by performing a query according to the information of the first UE or the information of the second UE, and may request an SM-DP module to convert the eID of the first UE or the eID of the second UE into an integrated circuit card identity (ICCID) of the first UE or an ICCID of the second UE.
The information of the first UE or the information of the second UE may include identity information assigned to a user by an SP and identity information of the first UE or second UE, and is used for dual authentication on the first UE or second UE so as to prevent other people from illegally transferring a subscription of the second UE. The eID may be a globally unique identity of an eUICC.
The first UE and second UE may be UEs using the eUICC, for example, mobile phones, tablet personal computers, personal digital assistants, and electricity meters. The first UE may be a UE that needs to acquire the subscription, and the second UE may be a UE that transfers the subscription.
S102. Transfer the eUICC subscription from the second UE to the first UE according to the subscription transfer request message, so that the first UE accesses an operator network according to transferred eUICC subscription data.
For example, the ICCID of the second UE in an OP used for access to the operator network may be replaced with the ICCID of the first UE, and then the updated OP is sent to the first UE to implement transfer of the eUICC subscription from the second UE to the first UE.
An entity executing the foregoing steps may be an SM-SR module.
In the subscription transfer method provided by this embodiment, a subscription transfer request message sent by a first UE or a second UE is received; and an eUICC subscription is transferred from the second UE to the first UE according to the subscription transfer request message, so that the first UE accesses an operator network according to transferred eUICC subscription data. Thereby, transfer of an eUICC subscription between UEs that use an eUICC can be implemented, and it is more flexible and convenient for a user to change a UE.
FIG. 2 is a flowchart of Embodiment 2 of a subscription transfer method according to the present invention. As shown in FIG. 2, on a basis of the embodiment shown in FIG. 1, the subscription transfer method in this embodiment may include the following steps.
S201. Receive a subscription transfer request message sent by a first UE or a second UE, where the first UE is a target UE to which an eUICC subscription is transferred, and the second UE is a source UE from which the eUICC subscription is transferred.
S202. Send an authentication request message to an SP device, so that the SP device determines whether to allow the eUICC subscription transfer.
For example, a binding relationship may exist between the subscription and a brand and model of a UE. If the first UE, that is, the target UE to which the subscription is transferred, does not meet requirements of the subscription on the brand and model of the UE, it is possible that transfer of the subscription to the first UE is not allowed.
S203. Receive an authentication response message sent by the SP device.
For example, the authentication response message may carry an indication indicating whether the subscription transfer is allowed. If the subscription transfer is allowed, the authentication response message further carries an ICCID and an IMEI of the second UE.
S204. Transfer the eUICC subscription from the second UE to the first UE according to the subscription transfer request message, so that the first UE accesses an operator network according to transferred eUICC subscription data.
An entity executing the foregoing steps may be an SM-SR module.
In the subscription transfer method provided by this embodiment, a subscription transfer request message sent by a first UE or a second UE is received; authentication is performed by an SP device; and after the authentication is successful, an eUICC subscription is transferred from the second UE to the first UE according to the subscription transfer request message, so that the first UE accesses an operator network according to transferred eUICC subscription data. Thereby, secure legal transfer of an eUICC subscription between UEs that use an eUICC can be implemented, and it is more flexible and convenient for a user to change a UE.
FIG. 3 is a flowchart of Embodiment 3 of a subscription transfer method according to the present invention. As shown in FIG. 3, on a basis of the embodiment shown in FIG. 1, the subscription transfer method in this embodiment may include the following steps.
S301. Receive a subscription transfer request message sent by a first UE or a second UE, where the first UE is a target UE to which an eUICC subscription is transferred, and the second UE is a source UE from which the eUICC subscription is transferred.
S302. Send a data transfer command message to the second UE.
The data transfer command message may carry a subscription transfer indication, which is used to indicate data transfer initiated to perform the subscription transfer.
S303. Receive user data that is sent by the second UE according to the data transfer command message, where the user data includes user data stored in an eUICC of the second UE and/or user data stored in a storage unit of the second UE.
Temporarily stored user data includes personal data (such as an address book and electricity meter readings), applications, and so on. If the user data can be carried in signaling, the user data may be carried in a data transfer response message. Otherwise, if the amount of data is large or a data format does not allow transfer in signaling, the second UE may request to create a data bearer to transfer the user data.
Further, optionally, an SM-SR module may store the user data, or the user data is sent to an SM-DP module for storage.
The user data may be stored in the SM-SR module or SM-DP module.
S304. Transfer the eUICC subscription from the second UE to the first UE according to the subscription transfer request message, so that the first UE accesses an operator network according to transferred eUICC subscription data.
S305. Send a data deletion command to the second UE, so that the second UE deletes the subscription data stored in the eUICC.
This step can ensure that the second UE that has transferred the user data out cannot access the network any more.
Further, a user may selectively delete the user data stored in the eUICC of the second UE and/or the user data stored in the storage unit of the second UE.
S306. Send the user data to the first UE.
It is understandable that if the user data is stored in an SM-DP module, the SM-DP module first sends the user data to the SM-SR module, and then the SM-SR module sends the user data to the first UE.
Further, optionally, the user data stored locally by the SM-SR module may be deleted, or the SM-SR module sends a deletion notification message to an SM-DP module, so that the SM-DP module deletes the stored user data.
An entity executing the foregoing steps may be an SM-SR module.
In the subscription transfer method provided by this embodiment, a subscription transfer request message sent by a first UE or a second UE is received; user data that is sent by the second UE according to the data transfer command message is received; an eUICC subscription is transferred from the second UE to the first UE according to the subscription transfer request message, so that the first UE accesses an operator network according to transferred eUICC subscription data; and then the user data is sent to the first UE. Thereby, transfer of subscription data and user data between UEs that use an eUICC can be implemented, and it is more flexible and convenient for a user to change a UE.
FIG. 4 is a flowchart of Embodiment 4 of a subscription transfer method according to the present invention. As shown in FIG. 4, on a basis of the embodiment shown in FIG. 1, the subscription transfer method in this embodiment includes the following steps.
S401. Receive a subscription transfer request message sent by a first UE or a second UE, where the first UE is a target UE to which an eUICC subscription is transferred, and the second UE is a source UE from which the eUICC subscription is transferred.
S402. Send a subscription transfer notification message to a device in an MNO network, where the subscription transfer notification message includes identity information of the first UE and identity information of the second UE, so that the device in the MNO network replaces the identity information of the second UE in subscription data with the identity information of the first UE.
For example, the identity information of the first UE may include an ICCID and/or an IMEI of the first UE, and the identity information of the second UE may include an ICCID and/or an IMEI of the second UE. The subscription transfer notification message may further include a subscription transfer indication used to indicate that subscription transfer will be performed between the first UE and the second UE. If the subscription data in the network of the MNO includes an ICCID and/or an IMEI, the device in the MNO network replaces the ICCID and/or IMEI of the second UE in the subscription data with the ICCID and/or IMEI of the first UE. The ICCID and IMEI may be stored in a home location register (HLR) or a home subscriber server (HSS), or stored in other network nodes.
Replacing the ICCID and/or IMEI in the subscription data in the device in the MNO network may ensure that after the subscription transfer, the MNO network can recognize the first UE and provide services for the first UE.
Another possible implementation manner of S402 may be as follows. First, a subscription transfer notification message is sent to an SM-DP module, where the subscription transfer notification message carries an eID and/or an IMEI of the first UE, an eID and/or an IMEI of the second UE, and a subscription transfer indication; upon reception of the subscription transfer notification message, the SM-DP module converts the received eID of the first UE and eID of the second UE into the ICCID of the first UE and the ICCID of the second UE; then the SM-DP module sends a subscription transfer notification message to the device in the MNO network, where the subscription transfer notification message carries the ICCID and/or IMEI of the first UE, the ICCID and/or IMEI of the second UE, and the subscription transfer indication; if the subscription data in the MNO network includes an ICCID and/or an IMEI, the device in the MNO network replaces the ICCID and/or IMEI of the second UE in the subscription data with the ICCID and/or IMEI of the first UE.
It is understandable that in a case in which the subscription data in the MNO network does not include the ICCID and IMEI of the second UE, the device in the MNO network does not need to replace the identity information of the UE.
S403. Receive a subscription transfer acknowledgement message fed back by the device in the MNO network.
S404. Send an OP request message that includes the identity information of the first UE and the identity information of the second UE to an SM-DP module, so that the SM-DP module replaces the identity information of the second UE corresponding to an OP with the identity information of the first UE to obtain an updated OP.
For example, according to the OP request message, the SM-DP module may replace the ICCID of the second UE corresponding to the OP with the ICCID of the first UE.
S405. Receive the updated OP sent by the SM-DP module, and send the updated OP to the first UE.
The UE may access the operator network by using the OP. Therefore, the SM-DP replaces the ICCID of the second UE corresponding to the OP with the ICCID of the first UE to obtain the updated OP, and sends the updated OP to the SM-SR module, and then the SM-SR sends the updated OP to the first UE. Therefore, the first UE may obtain the updated OP in the subscription transfer process.
An entity executing the foregoing steps may be an SM-SR module.
In the subscription transfer method provided by this embodiment, a subscription transfer request message sent by a first UE or a second UE is received, so that a device in an MNO network replaces identity information of the second UE in subscription data with identity information of the first UE, and that an SM-DP module replaces the identity information of the second UE corresponding to an OP with the identity information of the first UE; and then the OP is sent to the first UE. Thereby, transfer of an eUICC subscription between UEs that use an eUICC can be implemented, and it is more flexible and convenient for a user to change a UE.
FIG. 5 is a flowchart of Embodiment 5 of a subscription transfer method according to the present invention. As shown in FIG. 5, on a basis of the embodiment shown in FIG. 1, the subscription transfer method in this embodiment includes the following steps.
S501. Receive a subscription transfer request message sent by a first UE or a second UE, where the first UE is a target UE to which an eUICC subscription is transferred, and the second UE is a source UE from which the eUICC subscription is transferred.
S502. Send a subscription modification request message that includes identity information of the first UE and identity information of the second UE to a device in an MNO network, so that the device in the MNO network assigns new network access authentication parameters to the first UE, uses the new network access authentication parameters and the identity information of the first UE to replace network access authentication parameters corresponding to the second UE and the identity information of the second UE in subscription data, and uses the new network access authentication parameters and the identity information of the first UE to request an SM-DP module to generate an OP corresponding to the first UE.
For example, the subscription modification request message may be used to indicate a situation in which the second UE is lost. The device in the MNO network assigns the new network access authentication parameters such as an international mobile subscriber identity (IMSI) and authentication key K to the first UE according to the received subscription modification request message, and uses the newly assigned network access authentication parameters and an ICCID and/or an IMEI of the first UE to replace old network access authentication parameters and an ICCID and/or an IMEI of the second UE in the subscription data.
Another possible implementation manner of S502 may be as follows. First, a subscription transfer notification message is sent to the SM-DP module, where the subscription transfer notification message carries an eID and/or an IMEI of the first UE, an eID and/or an IMEI of the second UE, and a subscription transfer indication; upon reception of the subscription transfer notification message, the SM-DP converts the received eID of the first UE and eID of the second UE into the ICCID of the first UE and the ICCID of the second UE; and then the SM-DP module sends a subscription transfer notification message to the device in the MNO network, where the subscription transfer notification message carries the ICCID and/or IMEI of the first UE, the ICCID and/or IMEI of the second UE, and the subscription transfer indication, so that the device in the MNO network assigns the new network access authentication parameters to the first UE, uses the new network access authentication parameters and the identity information of the first UE to replace the old network access authentication parameters and the identity information of the second UE in the subscription data, and uses the new network access authentication parameters and the identity information of the first UE to request the SM-DP module to generate the OP corresponding to the first UE.
It is understandable that in a case in which the subscription data in the MNO network does not include the ICCID and IMEI of the second UE, the device in the MNO network does not need to replace the identity information of the UE.
S503. Receive a subscription transfer acknowledgement message fed back by the device in the MNO network.
S504. Send an OP request message that includes the identity information of the first UE to the SM-DP module.
S505. Receive an OP sent by the SM-DP module, and send the OP to the first UE.
In the subscription transfer method provided by this embodiment, a subscription transfer request message sent by a first UE is received; and then a subscription modification request message is sent to a device in an MNO network, so that the device in the MNO network assigns new network access authentication parameters to the first UE, and uses the new network access authentication parameters and identity information of the first UE to replace old network access authentication parameters and identity information of the second UE in subscription data; the device in the MNO's network requests an SM-DP module to generate a new OP for the first UE, and sends the generated OP to the first UE. Thereby, transfer of an eUICC subscription between UEs that use an eUICC can be implemented, and it is more flexible and convenient for a user to change a UE.
FIG. 6A and FIG. 6B are a flowchart of Embodiment 6 of a subscription transfer method according to the present invention. As shown in FIG. 6A and FIG. 6B, the subscription transfer method provided by the present invention is described in detail in this embodiment by using an example in which a first UE initiates subscription transfer, both the first UE and a second UE may access a network, the first UE is a new UE (that is, the first UE is a target UE to which an eUICC subscription is transferred), the second UE is an old UE (that is, the second UE is a source UE from which the eUICC subscription is transferred), and SP authentication is performed. The method may include the following steps.
S601. A user activates a provisioning profile (PP) of an eUICC in a new UE.
Activating the PP of the eUICC in the new UE may ensure that communication can be performed between the new UE and an SM-SR module.
S602. The new UE sends an OP download request message to an SM-SR module.
The request message may carry an eID and/or an IMEI of the new UE, information of an old UE, an SP device address, and a subscription transfer indication. The information of the old UE may include identity information assigned to the user by an SP device and identity information of the old UE, which are used to perform dual authentication on the old UE and prevent other people from illegally transferring a subscription of the old UE. The eID may be a unique identity of the eUICC.
The new UE and old UE may be UEs using the eUICC, for example, mobile phones, tablet personal computers, personal digital assistants, and electricity meters. The new UE may be a UE that needs to acquire the subscription, and the old UE may be a UE that transfers the subscription.
S603. The SM-SR module authenticates whether the eUICC of the new UE is legal.
For example, an eUICC certificate may be used to perform authentication.
S604. If the eUICC of the new UE passes the authentication in S603, the SM-SR module sends subscription transfer request message to an SP device, where the subscription transfer request information carries an eID and/or an IMEI of the new UE and information of the old UE.
S6051. The SP device obtains an eID and/or an IMEI of the old UE by performing a query according to the information of the old UE.
S6052. The SP device verifies whether to allow the subscription transfer between the new UE and the old UE.
For example, a binding relationship may exist between the subscription and a brand and model of a UE. If the first UE, that is, the target UE to which the subscription is transferred, does not meet requirements of the subscription on the brand and model of the UE, it is possible that transfer of the subscription to the first UE is not allowed.
S606. The SP device sends a subscription transfer response message to the SM-SR module.
The subscription transfer response information carries an indication indicating whether the subscription transfer is allowed. If the subscription transfer is allowed, the subscription transfer response information further carries the eID and/or IMEI of the old UE.
S604 to S606 are steps where the SP device performs authentication on the new UE and old UE before the subscription transfer to verify whether the subscription transfer is allowed.
S607. The SM-SR module sends an eID conversion request message to an SM-DP module, where the eID conversion request message carries the eID of the new UE and the eID of the old UE.
S608. The SM-DP module converts the eID of the new UE and the eID of the old UE into an ICCID of the new UE and an ICCID of the old UE.
The eID is a globally unique identity of the eUICC. The ICCID is an integrated circuit card identity including a specific MNO code. Therefore, after the SM-DP module converts the eID into the ICCID, it is convenient for an MNO network to use the ICCID corresponding to the MNO network to recognize the corresponding eUICC.
S609. The SM-DP module sends the ICCID of the new UE and the ICCID of the old UE to the SM-SR module.
S610. The SM-SR module sends user data transfer command message to the old UE, where the user data transfer command information carries a subscription transfer indication.
The subscription transfer indication carried in the data transfer command information is used to indicate data transfer initiated to perform the subscription transfer.
S611. The old UE sends user data stored in the eUICC and user data stored in a specific storage unit in the UE to the SM-SR module for temporary storage, or the data is stored to a temporary storage unit of the SM-DP module through the SM-SR module.
The temporarily stored user data may be indexed by using the ICCID of the old UE. The user data includes personal data (for example, an address book and electricity meter readings), applications, and so on. If the user data can be carried in a signaling message, the user data may be carried in a data transfer response message. Otherwise, if the amount of data is large or a data format does not allow transfer in signaling, the old UE may request to create a data bearer to transfer the user data.
S612. The SM-SR module sends a subscription transfer notification to a device in an MNO network, notifying the device in the MNO network that the subscription of the old UE will be transferred to the new UE, where the subscription transfer notification carries the ICCID and/or IMEI of the new UE, the ICCID and/or IMEI of the old UE, and a subscription transfer indication.
Another possible implementation manner of S612 may be as follows. The SM-SR module first sends a subscription transfer notification message to the SM-DP, where the subscription transfer notification message carries the eID and/or IMEI of the new UE, the eID and/or IMEI of the old UE, and a subscription transfer indication; upon reception of the subscription transfer notification message, the SM-DP module converts the received eID of the new UE and eID of the old UE into the ICCID of the new UE and the ICCID of the old UE; and then the SM-DP module sends a subscription transfer notification message to the device in the MNO network, where the subscription transfer notification message carries the ICCID and/or IMEI of the new UE, the ICCID and/or IMEI of the old UE, and the subscription transfer indication. S608 is not required in this implementation manner.
S613. If subscription data in the MNO network includes an ICCID and/or an IMEI, the device in the MNO network replaces the ICCID and/or IMEI of the old UE in the subscription data with the ICCID and/or IMEI of the new UE.
Replacing the ICCID and/or IMEI in the subscription data in the device in the MNO network may ensure that after the subscription transfer, the MNO network can recognize the new UE and provide services for the new UE.
It is understandable that in a case in which the subscription data in the MNO network does not include the ICCID and/or IMEI of the old UE, the device in the MNO network does not need to replace the ICCID and/or IMEI of the UE.
S614. The device in the MNO network feeds back a subscription transfer confirmation message to the SM-SR module.
Another possible implementation manner of S614 may be as follows. The device in the MNO network first sends subscription transfer acknowledgement information that carries the ICCID of the new UE and the ICCID of the old UE to the SM-DP module; upon reception of the subscription transfer acknowledgement information, the SM-DP module converts the received ICCID of the new UE and ICCID of the old UE into the eID of the new UE and the eID of the old UE; and then the SM-DP module sends subscription transfer acknowledgement information that carries the eID of the new UE and the eID of the old UE to the SM-SR module.
S615. The SM-SR module sends an OP request message to the SM-DP module, where the message includes the ICCID of the new UE and the ICCID of the old UE.
S6161. The SM-DP module changes the ICCID of the old UE corresponding to an OP into the ICCID of the new UE.
S6162. The SM-DP module sends the OP of the new UE to the SM-SR module.
S617. The SM-SR module sends the OP of the new UE to the new UE.
The UE may access the operator network by using the OP. Therefore, the SM-DP module changes the ICCID of the old UE corresponding to the OP into the ICCID of the new UE, and sends the OP of the new UE to the SM-SR module. Therefore, the new UE can obtain the OP in the subscription transfer process.
S618. The new UE activates the OP, and accesses the MNO network.
S619. The new UE confirms with the SM-SR module that the subscription is established successfully.
S6201. If the user data is stored in the SM-DP module in S611, the SM-SR module requests the user data from the SM-DP module.
S6202. The SM-DP module sends the user data to the SM-SR module.
S621. The SM-SR module sends the user data to the new UE.
The user data may be carried in signaling, or the UE may also be requested to create a data bearer for transfer.
S622. After the user data transfer is complete, the new UE sends a message to the SM-SR module, notifying the SM-SR module that the data transfer is complete.
S6231. If the user data is temporarily stored in the SM-DP module, the SM-SR module requests the SM-DP module to delete the temporarily stored user data.
S6232. The SM-DP module deletes the locally stored user data.
S6233. The SM-DP module notifies the SM-SR module after the locally stored user data is deleted.
S6234. If the user data is temporarily stored in the SM-SR module, the SM-SR module deletes the local user data.
S624. The SM-SR module sends a deletion command to the old UE.
S625. The old UE deletes the subscription data in the eUICC and related services, and deletes the user data stored in the eUICC and a memory of the UE.
Further, optionally, the user may selectively delete the user data in the eUICC and a memory of the UE.
S626. The old UE sends deletion acknowledgment information to the SM-SR module.
S627. The SM-SR module confirms with the SP device that the subscription transfer is complete.
In the subscription transfer method provided by this embodiment, a subscription transfer request message sent by a new UE is received; authentication is performed by an SP device, and user data in an old UE is transferred to the new UE; and then a device in an MNO network replaces identity information of the old UE in subscription data with identity information of the new UE, and an SM-DP module replaces the identity information of the old UE corresponding to an OP with the identity information of the new UE; then the OP is sent to the new UE. Thereby, secure legal transfer of an eUICC subscription between UEs that use an eUICC can be implemented, and it is more flexible and convenient for a user to change a UE.
A subscription transfer method provided by the present invention is described in detail in Embodiment 7 by using an example in which a second UE initiates subscription transfer, both a first UE and the second UE may access a network, the first UE is a new UE, the second UE is an old UE, and authentication is performed by an SP device.
