Abstract

The present disclosure relates to a communication method and system for converging a 5^th-Generation (5G) communication system for supporting higher data rates beyond a 4^th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus of a wireless network are disclosed. The method includes transmitting a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier, and receiving a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

Claims

1. A method of a wireless network, the method comprising:

transmitting a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier; and

receiving a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

2. The method of claim 1, wherein the SCEF further performs an authorization to check whether the SCS/AS is authorized to request the allocation of the MBMS group identifier.

3. The method of claim 1, wherein the SCEF transmits a second request message including the external group identifier and the SCS/AS identifier to request subscriber information to a home subscriber server (HSS), and receives a second response message including routing information for a broadcast/multicast service center (BM-SC) from the HSS.

4. The method of claim 3, wherein the SCEF transmits a third request message including the external group identifier to request the MBMS group identifier to the BM-SC, and receives a third response message including the MBMS group identifier.

5. The method of claim 3, wherein the routing information for the BM-SC comprises at least one of a BM-SC identifier and a BM-SC internet protocol (IP) address.

6. A method of a wireless network, the method comprising:

receiving a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier; and

transmitting a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

7. The method of claim 6, further comprising:

performing an authorization to check whether the SCS/AS is authorized to request the allocation of the MBMS group identifier.

8. The method of claim 6, further comprising:

transmitting a second request message including the external group identifier and the SCS/AS identifier to request subscriber information to a home subscriber server (HSS); and

receiving a second response message including routing information for a broadcast/multicast service center (BM-SC) from the HSS.

9. The method of claim 8, further comprising:

transmitting a third request message including the external group identifier to request the MBMS group identifier to the BM-SC; and

receiving a third response message including the MBMS group identifier.

10. The method of claim 8, wherein the routing information for the BM-SC comprises at least one of a BM-SC identifier and a BM-SC internet protocol (IP) address.

11. An apparatus for a wireless network, the apparatus comprising:

a transceiver configured to transmit and receive signals;

a controller configured to control the transceiver to;

transmit a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier, and

receive a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

12. The apparatus of claim 11, wherein the SCEF further performs an authorization to check whether the SCS/AS is authorized to request the allocation of the MBMS group identifier.

13. The apparatus of claim 11, wherein the SCEF transmits a second request message including the external group identifier and the SCS/AS identifier to request subscriber information to a home subscriber server (HSS), and receives a second response message including routing information for a broadcast/multicast service center (BM-SC) from the HSS.

14. The apparatus of claim 13, wherein the SCEF transmits a third request message including the external group identifier to request the MBMS group identifier to the BM-SC, and receives a third response message including the MBMS group identifier.

15. The apparatus of claim 13, wherein the routing information for the BM-SC comprises at least one of a BM-SC identifier and a BM-SC internet protocol (IP) address.

16. An apparatus for a wireless network, the apparatus comprising:

a transceiver configured to transmit and receive signals;

a controller configured to control the transceiver to;

receive a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier, and

transmit a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

17. The apparatus of claim 16, wherein the controller is further configured to control to perform an authorization to check whether the SCS/AS is authorized to request the allocation of the MBMS group identifier.

18. The apparatus of claim 16, wherein the controller is further configured to control the transceiver to transmit a second request message including the external group identifier and the SCS/AS identifier to request subscriber information to a home subscriber server (HSS), and to receive a second response message including routing information for a broadcast/multicast service center (BM-SC) from the HSS.

19. The apparatus of claim 18, wherein the controller is further configured to control the transceiver to transmit a third request message including the external group identifier to request the MBMS group identifier to the BM-SC, and to receive a third response message including the MBMS group identifier.

20. The apparatus of claim 18, wherein the routing information for the BM-SC comprises at least one of a BM-SC identifier and a BM-SC internet protocol (IP) address.
