Apparatuses to authorize and enable/disable enhanced coverage functionality
Apparatuses of wireless communication systems are disclosed. A User Equipment (UE) stores an enhanced coverage restricted parameter from a Mobility Management Entity (MME), and operates in the enhanced coverage mode if the enhanced coverage restricted parameter indicates that the UE is not restricted. The MME decodes an enhanced coverage restricted parameter received from a Home Subscriber Server (HSS), and generates a message to send the enhanced coverage restricted parameter to the UE. An eNode B decodes a message from the UE, the message indicating that the UE supports restriction for use of enhanced coverage. The eNB decodes an S1 Application Protocol (S1-AP) initial context set-up request message configured to indicate an enhanced coverage restricted parameter, the message received from the MME. The eNB operates in the enhanced coverage mode for the UE unless the enhanced coverage restricted parameter indicates that the enhanced coverage is restricted.
1. An apparatus for a service capability exposure function (SCEF) of a wireless communication system, the apparatus comprising:
a memory interface to send or receive, to or from a memory device, a server identifier (ID); and
a processor to:
process an enhanced coverage request from a server, the enhanced coverage request including the server ID and a request type, wherein the request type indicates if the enhanced coverage request is to query a status of, or to enable, or to disable the enhanced coverage restriction;
determine if the server is not authorized to perform the enhanced coverage request, if the enhanced coverage request is malformed, and if the server has exceeded a quota or rate of submitting enhanced coverage requests;
prepare a second enhanced coverage request to be sent to a home subscriber server (HSS), wherein the second enhanced coverage request is used to set a value of an enhanced coverage restriction parameter based on the request type when the request type indicates that the enhanced coverage request is to enable or disable the enhanced coverage restriction,
wherein a user equipment (UE) is informed of the value of the enhanced coverage restriction parameter at a Routing Area Update (RAU) procedure or a Tracking Area Update (TAU) procedure, the enhanced coverage restricted parameter indicating whether the UE is restricted from operating in an enhanced coverage mode;
receive an SCEF reference ID and a cause value from the HSS, wherein the cause value indicates whether the enhanced coverage request succeeded or failed; and
prepare an enhanced coverage response to be sent to the server to indicate a result from the enhanced coverage request.
2. The apparatus of claim 1 , wherein the enhanced coverage request further includes an external ID or a mobile station international subscriber directory number (MSISDN).
3. The apparatus of claim 1 , wherein the enhanced coverage request enables the third-party service provider to query a status of, enable, or disable enhanced coverage restrictions per user equipment.
4. The apparatus of claim 1 , wherein the processor is further to assign the SCEF reference ID to the enhanced coverage request.
5. The apparatus of claim 4 , wherein the second enhanced coverage request comprises an external ID or mobile station international subscriber directory number (MSISDN), SCEF ID, the SCEF Reference ID, and the request type.
6. The apparatus of claim 1 , wherein the enhanced coverage response includes the cause value that indicates whether the enhanced coverage request succeeded or failed.
7. The apparatus of claim 1 , wherein the server comprises at least one of a services capability server (SCS) and an application server (AS).
8. A non-transitory computer-readable storage medium having computer-readable instructions stored thereon, the computer-readable instructions to, when executed, instruct a processor of a service capability exposure function (SCEF) node to:
receive an enhanced coverage request from a server comprising a request type, wherein the request type indicates if the enhanced coverage request is to query a status of, or to enable, or to disable the enhanced coverage restriction;
determine if the server is not authorized to perform the enhanced coverage request, if the enhanced coverage request is malformed, and if the server has exceeded a quota or rate of submitting enhanced coverage requests;
send a second enhanced coverage request to be sent to a home subscriber server (HSS), wherein the second enhanced coverage request is used to set a value of an enhanced coverage restriction parameter based on the request type when the request type indicates that the enhanced coverage request is to enable or disable the enhanced coverage restriction,
wherein a user equipment (UE) is informed of the value of the enhanced coverage restriction parameter at a Routing Area Update (RAU) procedure or a Tracking Area Update (TAU) procedure, the enhanced coverage restricted parameter indicating whether the UE is restricted from operating in an enhanced coverage mode;
receive an SCEF reference identifier and a cause value from the HSS, wherein the cause value indicates whether the enhanced coverage request succeeded or failed; and
prepare an enhanced coverage response to be sent to the server to indicate a result from the enhanced coverage request.
9. The non-transitory computer-readable storage medium of claim 8 , wherein the enhanced coverage request includes an external identifier or a mobile station international subscriber directory number (MSISDN), a server identifier, and the request type.
10. The non-transitory computer-readable storage medium of claim 8 , wherein
the second enhanced coverage request to be sent to the HSS comprises an external identifier or a mobile station international subscriber directory number (MSISDN), SCEF identifier, the SCEF Reference identifier, and the request type.
11. The non-transitory computer-readable storage medium of claim 8 , wherein the enhanced coverage response includes the cause value that indicates whether the enhanced coverage request succeeded or failed.
12. The non-transitory computer-readable storage medium of claim 8 , wherein the server comprises at least one of a services capability server (SCS) and an application server (AS).
13. An apparatus for a home subscriber server (HSS), the apparatus comprising:
an interface to receive, from a service capability exposure function (SCEF), an enhanced coverage request, wherein the enhanced coverage request comprises a request type, wherein the request type indicates if the enhanced coverage request is to query a status of, or to enable, or to disable the enhanced coverage restriction; and
a processor to:
examine an enhanced coverage request message to determine:
whether parameters included in the enhanced coverage request are in an acceptable range, and
whether enhanced coverage is supported by a serving mobility management entity (MME) or supporting node (SGSN);
set a value of an enhanced coverage restriction parameter based on the request type when the request type indicates that the enhanced coverage request is to enable or disable the enhanced coverage restriction, wherein a user equipment (UE) is informed of the value of the enhanced coverage restriction parameter at a Routing Area Update (RAU) procedure or a Tracking Area Update (TAU) procedure, the enhanced coverage restricted parameter indicating whether the UE is restricted from operating in an enhanced coverage mode; and
prepare an enhanced coverage response to be sent to the SCEF to indicate a result from the enhanced coverage request, wherein the enhanced coverage response includes an SCEF reference identifier and a cause value that indicates whether the enhanced coverage request succeeded or failed.
14. The apparatus of claim 13 , wherein the enhanced coverage request further comprises an external identifier or mobile station international subscriber directory number (MSISDN), SCEF identifier, and the SCEF Reference identifier.
15. The apparatus of claim 14 , wherein if the request type is to get a current status of enhanced coverage, the processor is further to retrieve a value of an Enhanced Coverage Restricted/Allowed parameter, and send the value of the Enhanced Coverage Restricted/Allowed parameter to the SCEF.
16. The apparatus of claim 14 , further comprising a second interface to send an Insert Subscriber Data Request comprising type, SCEF identifier, SCEF Reference identifier, and the SCEF Reference identifier message to a mobility function node if the request type is to enable or to disable enhanced coverage.
