Abstract

A profile processing method, a profile processing apparatus, a user terminal (UE), and an embedded universal integrated circuit card (eUICC) conducive to profile processing efficiency enhancement of the eUICC and user experience improvement, where the method includes generating, by a local profile assistant (LPA) of a first UE (UE1), a profile request according to information about an eUICC of a second UE (UE2), sending the profile request, receiving, by the LPA, a profile request response, where the profile request response includes at least a profile of the eUICC, and forwarding, by the LPA, the profile to the eUICC.

First claim

1 . A profile processing method, comprising:
generating, by a local profile assistant (LPA) of a first terminal (UE 1 ), a profile request according to information about an embedded universal integrated circuit card (eUICC) of a second terminal (UE 2 ); sending, by the LPA, the profile request; receiving, by the LPA, a profile request response comprising at least a profile of the eUICC; and forwarding, by the LPA, the profile to the eUICC.

2 . The method according to claim 1 , wherein sending the profile request comprises sending, by the LPA, the profile request to a profile server.

3 . The method according to claim 2 , wherein after sending the profile request and before receiving the profile request response, the method further comprises:
receiving, by the LPA, a key negotiation request from the profile server; forwarding, by the LPA, the key negotiation request to the eUICC when the LPA determines, according to information carried in the key negotiation request, that a target receiver of the key negotiation request comprises the eUICC; receiving, by the LPA, a key negotiation response from the eUICC; and forwarding, by the LPA, the key negotiation response to the profile server.

4 . The method according to claim 1 , wherein before generating the profile request, the method further comprises:
obtaining, by the LPA, the information about the eUICC; or obtaining, by the LPA, the information about the eUICC, and displaying, by the LPA, the obtained information about the eUICC and operator information.

5 . The method according to claim 4 , wherein before obtaining the information about the eUICC, the method further comprises:
establishing, by the LPA, a secure channel between the LPA and the eUICC; and obtaining, by the LPA using the secure channel, the information about the eUICC.

6 . The method according to claim 4 , wherein before receiving the profile request response, the method further comprises:
establishing, by the LPA, a secure channel between the LPA and the eUICC; and transmitting, by the LPA using the secure channel the profile.

7 . The method according to claim 5 , further comprising re-establishing, by the LPA, a secure channel between the LPA and the eUICC when the LPA detects that the secure channel is disabled.

8 . The method according to claim 5 , wherein establishing the secure channel between the LPA and the eUICC comprises:
broadcasting, by the LPA, a service search request, establishing a local coupling between the LPA and the UE 2 or between the LPA and the eUICC, and establishing the secure channel between the LPA and the eUICC based on the local; receiving, by the LPA, a broadcast service search request, establishing the local coupling between the LPA and the UE 2 or between the LPA and the eUICC, and establishing the secure channel between the LPA and the eUICC based on the local coupling; or receiving, by the LPA, a broadcast service search request carrying an eUICC service indicator, completing device discovery between the LPA and the eUICC according to the eUICC service indicator, establishing the local coupling between the LPA and the UE 2 or between the LPA and the eUICC, and establishing the secure channel between the LPA and the eUICC based on the local coupling.

9 . The method according to claim 1 , wherein the information about the eUICC comprises at least one of the following:
a device identity of the UE 2 (UE 2 -ID); capability information of the UE 2 ; a card identity of the eUICC (EID); or an eUICC information set (EIS) of the eUICC.

10 . The method according to claim 1 , wherein the profile request comprises at least one of the following:
a device identity of the UE 1 (UE 1 -ID); a device identity of the UE 2 (UE 2 -ID); capability information of the UE 2 ; a card identity of the eUICC (EID); or an eUICC information set (EIS) of the eUICC.

11 . (canceled)

12 . The method according to claim 1 , wherein forwarding the profile to the eUICC comprises:
extracting, by the LPA, the profile from the received profile request response, and forwarding the extracted profile to the eUICC: or forwarding, by the LPA to the eUICC, the profile request response carrying the profile.

13 . The method according to claim 1 , wherein after forwarding the profile to the eUICC, the method further comprises:
sending, by the LPA to the eUICC, a profile activation request to activate the profile; sending, by the LPA to the eUICC, a profile disabling request to disable the profile; or sending, by the LPA to the eUICC, a profile delete request to delete the profile.

14 . The method according to claim 1 , wherein comprises generating, by the LPA, the profile request according to the information about the eUICC when the LPA detects an operator network selection instruction, and wherein an operator network provides a network service to the eUICC.

15 . A profile processing profile-method, comprising:
receiving, by an embedded universal integrated circuit card (eUICC) of a second terminal (UE 2 ), a key negotiation request received from a local profile assistant (LPA) of a first terminal (UE 1 ); sending, by the eUICC, a key negotiation response to the LPA; and receiving, by the eUICC, a profile encrypted according to the key negotiation response from the LPA.

16 . The profile processing method according to claim 15 , wherein before receiving the key negotiation request from the LPA, the method further comprises sending, by the eUICC, information about the eUICC to the LPA.

17 . The profile processing method according to claim 16 , wherein before sending the information about the eUICC to the LPA, the method further comprises:
establishing, by the eUICC, a secure channel between the LPA and the eUICC; and sending, by the eUICC using the secure channel, the information about the eUICC to the LPA.

18 . The method according to claim 15 , wherein before receiving the profile encrypted according to the key negotiation response from the LPA, the method further comprises:
establishing, by the eUICC, a secure channel between the LPA and the eUICC; and receiving, by the eUICC using the secure channel, the profile.

19 . The method according to claim 17 , wherein after establishing the secure channel between the LPA and the eUICC, the method further comprises disabling, by the eUICC, the secure channel when the eUICC detects that establishment duration of the secure channel is greater than or equal to a preset threshold.

20 .- 70 . (canceled)

71 . The method according to claim 18 , wherein after establishing the secure channel between the LPA and the eUICC, the method further comprises disabling, by the eUICC, the secure channel when the eUICC detects that establishment duration of the secure channel is greater than or equal to a preset threshold.

72 . A user terminal, comprising:
a local profile assistant (LPA); a memory coupled to the LPA and configured to store instructions; and a processor coupled to the LPA and the memory, wherein the instructions cause the processor to be configured to:
generate, using the LPA, a profile request according to information about an embedded universal integrated circuit card (eUICC) of a second terminal (UE 2 );
send the profile request;
receive a profile request response comprising at least a profile of the eUICC; and
