Specifically, the terminal sends the first identifier, or the first identifier and the association identifier.

The first network element acquires a first identifier of the terminal, or the first identifier and the association identifier.

The first network element may be a newly added, independent network element, or may be combined with an existing network element. The first network element may also be referred to as a "first function", and any network device implementing the function may be the first network element.

The terminal may send the first identity directly to the first network element, or the first identity and the association identity.

The terminal may send the first identifier, or the first identifier and the association identifier, to the first network element in a forwarding manner of the other network element (the second network element).

The second network element may be an access and mobility management function (Access and Mobility Management Function, AMF), a network opening function (Network Exposure Function, NEF), a location management function (Location Management Function, LMF), etc.

The first identity may be a user permanent identity (subscription permanent identifier, SUPI), a general public user identity (generic public subscription identifier, GPSI), a 5G globally unique temporary identity (5G globally unique temporary identifier,5G-GUTI), or the like.

One USIM in the multiple USIM terminal corresponds to one first identity.

The association identifier includes one or more of the following:

a permanent device identifier (permanent equipment identifier, PEI);

a global mobile device identifier (international mobile station equipment identity, IMEI);

a unique identifier pre-configured within the hardware;

a unique number pre-configured within the hardware;

a unique number is preconfigured in the hardware.

The associated identity may also be a hash or encrypted value of a second identity comprising one or more of the following identities:

PEI；

IMEI；

a unique identifier pre-configured within the hardware;

a unique number pre-configured within the hardware;

a unique number is preconfigured in the hardware.

and 0a, the first function sends a subscription request message to the NEF to request to obtain event notification that the UE supports the change of the multiple USIM characteristics.

0b, the NEF sends a subscription request message to the AMF requesting to obtain event notification that the UE supports a change in multiple USIM characteristics.

1. The UE sends a registration request message to the AMF, the registration request message carrying a support multiple USIM feature and an association ID.

When the UE performs an initial registration procedure through USIM1 and USIM2, respectively, the above steps 1 to 4 are performed, respectively. Because the association IDs received by the first function are the same, the first function may determine that the first and second first identities belong to the same UE according to the association IDs.

Before the UE sends an initial registration request through USIM1 and USIM2, the association ID is calculated. The association ID may be a value obtained by the UE performing a hash algorithm or an encryption algorithm on information of the UE (e.g., PEI, or a unique identification preconfigured in hardware, or a unique number/number preconfigured in hardware). The specific algorithm is configured within the UE.

1. the AMF or UE sends to the LMF that the UE supports the multiple USIM feature.

2. The LMF decides to trigger the first function to locate the UE according to the multi-USIM characteristic and the position QoS supported by the UE. The LMF sends a location request message to the first function, the location request message carrying a first identification.

4. The first function searches locally stored information according to the first identity, and discovers that the UE also supports the second first identity. The first function sends a location request message to the GMLC within the PLMN assigned the first identifier and the second first identifier, respectively, the location request message carrying the first identifier and the second first identifier, respectively.

5. GMLC1 and GMLC2 initiate a positioning procedure for the UE, respectively, and the specific procedure is not described here again.

6. GMLC1 and GMLC2 send location reply messages to the first function, respectively, the location reply messages carrying the UE location.

7. The first function determines the final UE location from the two UE locations and then returns the UE location to the application.

It should be noted that: steps 4-7 may be generalized to multi-USIM co-location as shown in fig. 8, steps 4-7 being not shown in fig. 8 with steps 6-9 in the above embodiments.

In some embodiments, the method further comprises:

the first network element receives privacy information of the terminal;

the first network element stores the privacy information.

In some embodiments, the method further comprises:

the first network element performs privacy checking;

Specifically, in the embodiment of the present application, the privacy information of the terminal may include a privacy attribute of a location service (LoCation Services, LCS), and may further include privacy information provided by the UE or the AF.

The LCS privacy attribute includes a signed privacy attribute, whether the LCS client is allowed to acquire the UE location, and so on.

In the embodiment of the application, the UDM sends UE meaning information (e.g., LCS privacy attribute) to the first network element, which stores the LCS privacy attribute of the UE.

The UE or AF may also send the privacy information to the first network element directly or through the second network element.

When the first network element receives the location request, the first network element performs privacy check according to the locally stored LCS privacy attribute of the UE, that is, determines whether the LCS client is allowed to acquire the location of the UE, and if so, sends the location request to the GMLC in the PLMN. The PLMN may skip the privacy check procedure (i.e., the GMLC or AMF no longer performs privacy check).

According to the multi-USIM terminal information management method provided by the embodiment of the application, the privacy information of the terminal is uniformly managed through the first network element, so that unnecessary privacy inspection is avoided, and signaling overhead is reduced.

In some embodiments, the method further comprises:

Specifically, in the embodiment of the present application, after the first network element receives the location of the UE from the GMLC of the PLMN1, the first network element stores the location information and the timestamp of the UE.

When the first network element receives the positioning request of the PLMN1 and/or the PLMN2 again, the first network element judges whether UE position information meeting the position precision requirement and the time requirement exists according to the locally stored information, if so, the locally stored information is returned to the LCS client, otherwise, the first network element sends the position request to the GMLC in the PLMN1 and/or the PLMN 2.

According to the multi-USIM terminal information management method provided by the embodiment of the application, the terminal information is uniformly managed through the first network element, so that the position sharing is realized, the terminal is prevented from frequently carrying out unnecessary positioning measurement, the power consumption of the terminal is reduced, and the energy is saved.
