Abstract

Claims (25)

1 . A method performed by a network function service consumer entity, wherein the network function service consumer entity is a network data analytics function (NWDAF) entity or a home subscriber server (HSS), comprising:

sending a single request for retrieving at least two registration data sets related to a user equipment to a data management entity, wherein the single request comprises two or more corresponding registration data set names and wherein the data management entity is a unified data management (UDM) entity, and wherein the single request further comprises single network slice selection assistance information (S-NSSAI) and a data network name (DNN) which are only applicable when a registration data set name identifies session management function (SMF) registration for protocol data unit (PDU) sessions; and

receiving a single response from the data management entity, wherein the single response comprises at least two requested registration data sets related to the user equipment;

wherein the registration data set names include at least one of:

a registration data set name identifying session management function registration information;

a registration data set name identifying access and mobility management function (AMF) 3rd generation partnership project (3GPP) access registration information;

a registration data set name identifying AMF Non 3GPP access registration information;

a registration data set name identifying short message service function (SMSF) 3GPP access registration information; and

a registration data set name identifying SMSF Non 3GPP access registration information.

2 . The method according to claim 1 , wherein the single request is a hypertext transfer protocol HTTP GET request and the single response is an HTTP GET response.

3 . The method according to claim 2 , wherein the HTTP GET response includes:

a response code 200 OK and a response body containing at least two requested registration data set related to the user equipment; or

a response code 404 Not Found.

4 . The method according to claim 1 , wherein the single request further includes a user equipment identity representing the user equipment, in which the user equipment identity is a subscription permanent identifier (SUPI) or a generic public subscription identifier (GPSI).

5 . A network function service consumer entity, wherein the network function service consumer entity is a network data analytics function (NWDAF) entity or a home subscriber server (HSS), comprising:

a processor; and

a memory coupled to the processor, said memory containing instructions which, when executed by said processor, cause said network function service consumer entity to:

send a single request for retrieving at least two registration data sets related to a user equipment to a data management entity, wherein the single request comprises two or more corresponding registration data set names and wherein the data management entity is a unified data management (UDM) entity, and wherein the single request further comprises single network slice selection assistance information (S-NSSAI) and a data network name (DNN) which are only applicable when a registration data set name identifies session management function (SMF) registration for protocol data unit (PDU) sessions; and

receive a single response from the data management entity, wherein the single response comprises at least two requested registration data sets related to the user equipment;

wherein the registration data set names include at least one of:

a registration data set name identifying session management function registration information;

a registration data set name identifying access and mobility management function (AMF) 3rd generation partnership project (3GPP) access registration information;

a registration data set name identifying AMF Non 3GPP access registration information;

a registration data set name identifying short message service function (SMSF) 3GPP access registration information; and

a registration data set name identifying SMSF Non 3GPP access registration information.
