Abstract

Claims (51)

1. A method, performed by a network function (NF) for access and mobility management, for providing directions to a user equipment (UE) in a communication network, the method comprising:

determining if directions are to be transferred to the UE;

instructing a short message service function (SMSF) to generate, based on the determination, a message including the directions, wherein the directions refer to instructions for taking actions by a user of the UE for troubleshooting problems concerning operational parameters of the UE;

receiving, from the SMSF, the message including the directions; and

forwarding the message including the directions to the UE,

wherein the directions are related to adjusting the operational parameters of the UE, reporting an occurrence of a fault at the UE, tracing and correcting a fault occurring at the UE, and/or testing new NF(s) at the UE, and

wherein the message including the directions is transmitted over a Non-access Stratum.

2. The method of claim 1 , wherein the instructing is performed by transmitting, to the SMSF, contents concerning the directions and an identifier (ID) for the UE.

3. The method of claim 1 , wherein the method comprises, prior to the receiving:

determining whether a short message service (SMS) is reachable at the UE by initiating a procedure for paging the UE; and

if the SMS is reachable, notifying the SMSF of transmitting the message including the directions to the NF for access and mobility management.

4. The method of claim 1 , wherein the NF for access and mobility management is implemented by an access and mobility function (AMF).

5. An apparatus for providing directions to a user equipment (UE) in a communication network, the apparatus comprising:

processing circuitry;

memory containing instructions executable by the processing circuitry whereby the apparatus is operative to:

determine if directions are to be transferred to the UE;

instruct a short message service function (SMSF) to generate, based on the determination, a message including the directions, wherein the directions refer to instructions for taking actions by a user of the UE for troubleshooting problems concerning operational parameters of the UE;

receive, from the SMSF, the message including the directions; and

forward the message including the directions to the UE,

wherein the directions are related to adjusting the operational parameters of the UE, reporting an occurrence of a fault at the UE, tracing and correcting a fault occurring at the UE, and/or testing new NF(s) at the UE, and

wherein the message including the directions is transmitted over a Non-access Stratum.

6. A method, performed by a short message service function (SMSF), for providing directions to a user equipment (UE) in a communication network, the method comprising the SMSF:

receiving an instruction from a network function (NF), the instruction based on a determination if directions are to be transferred to the UE;

generating, in response receiving an instruction from the NF for access and mobility management, a message including the directions, wherein the directions refer to instructions for taking actions by a user of the UE for troubleshooting problems concerning operational parameters of the UE; and

transmitting, to the UE, the message including the directions via the NF for access and mobility management,

wherein the directions are concerned with adjusting the operational parameters of the UE, reporting an occurrence of a fault at the UE, tracing and correcting a fault occurring at the UE, and/or testing new NF(s) at the UE, and

wherein the message including the directions is transmitted over a Non-access Stratum.

7. The method of claim 6 , wherein the instruction includes contents concerning the directions and an identifier (ID) for the UE.

8. The method of claim 6 , wherein the method comprises, prior to the transmitting, inquiring whether a short message service (SMS) is reachable at the UE.

9. An apparatus for providing directions to a user equipment (UE) in a communication network, the apparatus comprising:

processing circuitry;

memory containing instructions executable by the processing circuitry whereby the apparatus is operative to:

receive an instruction from a network function (NF), the instruction based on a determination if directions are to be transferred to the UE;

generate, in response receiving an instruction from the NF for access and mobility management, a message including the directions, wherein the directions refer to instructions for taking actions by a user of the UE for troubleshooting problems concerning operational parameters of the UE; and

transmit, to the UE, the message including the directions via the NF for access and mobility management,

wherein the directions are related to adjusting the operational parameters of the UE, reporting an occurrence of a fault at the UE, tracing and correcting a fault occurring at the UE, and/or testing new NF(s) at the UE, and

wherein the message including the directions is transmitted over a Non-access Stratum.

10. A method, performed by a network function (NF) for user profile management, for providing directions to a user equipment (UE) in a communication network, the method comprising:

determining whether there are directions that need to be transferred to the UE, wherein the directions refer to instructions for taking actions by a user of the UE for troubleshooting problems concerning operational parameters of the UE; and

invoking, if there are directions that need to be transferred, SMS capability supplied by a short message service function (SMSF) by transmitting SMS contents including the directions, wherein the SMSF generates, based on the SMS contents, a message including the directions for the UE,

wherein the directions are related to adjusting the operational parameters of the UE, reporting an occurrence of a fault at the UE, tracing and correcting a fault occurring at the UE, and/or testing new NF(s) at the UE, and

wherein the message including the directions is transmitted over a Non-access Stratum.

11. The method of claim 10 , wherein the SMS contents further comprise an identifier (ID) for the UE.

12. The method of claim 10 , wherein the NF for user profile management is implemented by a unified database management (UDM).

13. An apparatus for providing directions to a user equipment (UE) in a communication network, the apparatus comprising:

processing circuitry;

memory containing instructions executable by the processing circuitry whereby the apparatus is operative to:

determining whether there are directions that need to be transferred to the UE, wherein the directions refer to instructions for taking actions by a user of the UE for troubleshooting problems concerning operational parameters of the UE; and

invoke, if there are directions that need to be transferred, SMS capability supplied by a short message service function (SMSF) by transmitting SMS contents including the directions, wherein the SMSF generates, based on the SMS contents, a message including the directions for the UE,

wherein the directions are related to adjusting the operational parameters of the UE, reporting an occurrence of a fault at the UE, tracing and correcting a fault occurring at the UE, and/or testing new NF(s) at the UE, and

wherein the message including the directions is transmitted over a Non-access Stratum.
