US 2020/0029205 A1 · COMMUNICATION METHOD AND DEVICE

Abstract

The present disclosure discloses a communication method performed by a management function entity, including: receiving a first request message sent by user equipment UE; sending a second request message to a storage function entity based on the first request message, where the second request message is used to request a security service identifier for the UE, and the security service identifier is used to indicate a security service procedure; receiving a response message including the security service identifier from the storage function entity; obtaining a target security service identifier based on the security service identifier, where the target security service identifier is used to indicate a security service procedure to be initiated by the management function entity; and initiating the security service procedure indicated by the target security service identifier. The present disclosure further discloses a communications device.

Dependent claims

A communication method, comprising:

receiving, by a session management function (SMF) entity, a packet data unit (PDU) session establishment request from user equipment (UE);
sending, by the session management function entity, a second request message to a storage function entity based on the PDU session establishment request, wherein the second request message is used to request a session management (SM) security service identifier for the UE, and the security service identifier is used to indicate an SM security service procedure;
receiving, by the session management function entity, a response message from the storage function entity, wherein the response message comprises the SM security service identifier;
obtaining, by the session management function entity, an SMF SM security service identifier based on the SM security service identifier, wherein the SMF SM security service identifier is used to indicate an SM security service procedure to be initiated by the SMF entity;
and
initiating, by the session management function entity, the SM security service procedure indicated by the SMF SM security service identifier.

3 more elements

An apparatus, comprising at least one processor coupled with a non-transitory storage medium storing executable instructions;

wherein the executable instructions, when executed by the at least one processor, cause the at least one processor to:
receive a packet data unit (PDU) session establishment request from user equipment (UE);
send a second request message to a storage function entity based on the PDU session establishment request, wherein the second request message is used to request a session management (SM) security service identifier for the UE, and the security service identifier is used to indicate an SM security service procedure;
receive a response message from the storage function entity, wherein the response message comprises the SM security service identifier;
obtain a session management function (SMF) SM security service identifier based on the SM security service identifier, wherein the SMF SM security service identifier is used to indicate an SM security service procedure to be initiated by the SMF entity;
and
initiate the SM security service procedure indicated by the SMF SM security service identifier.

4 more elements

A system, comprising:

a session management function (SMF) entity and a storage function entity, wherein
the SMF entity, configured to receive a packet data unit (PDU) session establishment request from user equipment (UE);
and send a second request message to the storage function entity based on the PDU session establishment request, wherein the second request message is used to request a session management (SM) security service identifier for the UE, and the security service identifier is used to indicate an SM security service procedure;
the storage function entity, configured to send a response message, wherein the response message comprises the SM security service identifier;
the SMF entity, further configured to obtain an SMF SM security service identifier based on the SM security service identifier, wherein the SMF SM security service identifier is used to indicate an SM security service procedure to be initiated by the SMF entity;
and initiate the SM security service procedure indicated by the SMF SM security service identifier.
