Abstract

A method and an apparatus for providing a service in a wireless communication system are disclosed. The method and apparatus are directed to 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 apparatus includes a terminal in the wireless communication system. The terminal includes a transceiver configured to transmit and receive a signal, and a processor configured to receive a first service request related to mission critical push to talk over LTE (MCPTT) over long term evolution (LTE), determine whether a first service corresponding to the first service request and a second service request being currently performed are simultaneously provided, and process the first service and the second service based on a priority of each of the service, services if the first service and the second service are not simultaneously provided.

Claims

1. A method by a terminal in a wireless communication system, the method comprising:

receiving a first service request related to mission critical push to talk (MCPTT);

determining whether a first service corresponding to the first service request and a second service request, being currently performed, are simultaneously provided; and

processing the first service and the second service based on a priority of each of the services, if the first service and the second service are not simultaneously provided.

2. The method of claim 1, wherein the processing of the first service and the second services comprises adjusting a media for a posterior service among each of the services.

3. The method of claim 2, wherein the adjusting of the media includes at least one of:

operations of ending and rejecting the posterior service,

holding until a prior order service ends,

converting into a service configured to be simultaneously provided with the media of the prior order service, and

forwarding to preset one or more other terminals.

4. The method of claim 1, wherein the priority of each of the services includes at least one of a priority of a user, a priority of a group, and a priority of a service.

5. A terminal in a wireless communication system, the terminal comprising:

a transceiver configured to transmit and receive a signal; and

a processor configured to;

receive a first service request related to mission critical push to talk (MCPTT),

determine whether a first service corresponding to the first service request and a second service request, being currently performed, are simultaneously provided, and

process the first service and the second service based on a priority of each of the services if the first service and the second service are not simultaneously provided.

6. The terminal of claim 5, wherein the processor is further configured to adjust a media for a posterior service among each of the services.

7. The terminal of claim 6, wherein the adjustment includes at least one of operations of ending and rejecting the posterior service, holding until a prior order service ends, converting into a service which configured to simultaneously provided with the media of the prior order service, and forwarding to another terminal.

8. The terminal of claim 5, wherein the priority includes at least one of a priority of a user, a priority of a group, and a priority of a service.

9. A method by a mission critical push to talk (MCPTT) server, the method comprising:

receiving a first service request from a first terminal, the first service request related to a second terminal;

determining whether a first service corresponding to the first service request and a second service, which is currently being performed by the second terminal, are simultaneously provided by the second terminal,

determining a process of the first service and the second service based on a priority of each of the services if the first service and the second service are not simultaneously provided; and

transmitting a service request message to the second terminal based on the determination.

10. The method of claim 9, wherein the determining of the process of the first service and the second services comprises adjusting a media for a posterior service among each of the services.

11. The method of claim 10, wherein the adjusting of the media includes at least one of operations of ending and rejecting the posterior service, holding until a prior order service ends, converting into a service which may be simultaneously provided with the media of the prior order service, and forwarding to preset one or more other terminals.

12. The method of claim 9, wherein the priority of each of the services includes at least one of a priority of a user, a priority of a group, and a priority of a service.

13. The method of claim 9, further comprising:

receiving a first floor request message from the first terminal;

receiving a second floor request message from the second terminal; and

transmitting a floor grant message to a prior order terminal based on a priority of the first terminal and the second terminal.

14. The method of claim 9, further comprising:

determining whether a number of group service target terminals for a group service is equal to or greater than a threshold, if the service request is a group service request; and

determining whether the group service is provided by multicast or unicast based on the number of the group service target terminals and the threshold.

15. The method of claim 9,

wherein each of the service requests is received through session initiation protocol (SIP) protocol, and

wherein the first service request includes location information on the first terminal, and the second service request includes location information on the second terminal.

16. A mission critical push to talk (MCPTT) server, the MCPTT server comprising:

a transceiver configured to transmit and receive a signal; and

a processor configured to;

receive a first service request from a first terminal, the first service request related to a second terminal,

determine whether a first service corresponding to the first service request and a second service, which is currently being performed by the second terminal, are simultaneously provided by the second terminal,

determine a process of the first service and the second service based on a priority of each of the services if the first service and the second service are not simultaneously provided, and

transmit a service request message to the second terminal based on the determination.

17. The MCPTT server of claim 16, wherein the priority includes at least one of a priority of a user, a priority of a group, and a priority of a service.

18. The MCPTT server of claim 16, wherein the processor is further configured to:

receive a first floor request message from the first terminal,

receive a second floor request message from the second terminal, and

transmit a floor grant message to a prior order terminal based on a priority of the first terminal and the second terminal.

19. The MCPTT server of claim 16, wherein the processor is further configured to:

determine whether a number of group service target terminals for at least one of the group services is equal to or greater than a threshold, if the service request is a group service request, and

determine whether the group service is provided by multicast or unicast based on the number of the group service target terminals and the threshold.

20. The method of claim 16,

wherein each of the service requests is received through session initiation protocol (SIP) protocol, and

wherein the first service request includes location information on the first terminal, and the second service request includes location information on the second terminal.
