Selective service method in multicast system
A multicast service of a 3GPP Universal Mobile Telecommunications System (UMTS) is disclosed. A multicast service stream identifier is provided so that each multicast area can receive different information for one service or one multicast service can be provided with different QoSs to areas. In addition, the multicast service stream identifier is provided which can selectively receive diverse menus or channels for one multicast service provided in the same area. Thus, by providing the multicast service stream identifier, users' desires for various services can be satisfied.
1. A selective service method of a multicast system in a system providing a multimedia broadcast/multicast service (MBMS), comprising:
attaching a service stream identifier (ID) to an MBMS data; and
multicasting the identifier-attached MBMS data stream.
2. The method of claim 1 , wherein the identifier comprises:
an MBMS service ID; and
an ID indicative of a kind of a lower service of the MBMS service.
3. The method of claim 2 , wherein the MBMS service ID consists of an access point number (APN) and an IP multicast address.
4. The method of claim 2 , wherein the ID indicative of a kind of a lower service is a multicast group ID.
5. The method of claim 3 , wherein the ID indicative of a kind of a lower service includes a multicast group ID and a multicast area ID.
6. The method of claim 3 , wherein the ID indicative of a kind of a lower service includes a multicast group ID, a multicast area ID and an UDP/TCP port number.
7. A selective service method of a multicast system in a system providing a multimedia broadcast/multicast service (MBMS), comprising:
attaching a first identifier (ID) for an MBMS data multicast service;
attaching a second identifier indicative of a kind of a lower service of an MBMS data; and
multicasting the MBMS data stream with the first and second identifier attached thereto.
8. The method of claim 7 , wherein the first identifier is an MBMS service ID.
9. The method of claim 7 , wherein the MBMS service ID consists of an access point number (APN) and an IP multicast address.
10. The method of claim 7 , wherein the second identifier is a multicast group ID.
11. The method of claim 7 , wherein the second identifier includes a multicast group ID and a multicast area ID.
12. The method of claim 7 , wherein the second identifier comprises:
a multicast group ID;
a multicast area ID; and
an UDP/TCP port number.
13. A selective service method of a multicast system in a system providing a multimedia broadcast/multicast service (MBMS), comprising:
classifying an entire multicast service area into certain units;
attaching an identifier of the classified area to a multicast data stream and transmitting it.
14. The method of claim 13 , wherein the entire multicast area is classified by multicast groups, by multicast areas and by multicast services.
15. The method of claim 13 , wherein the identifier is performed by a member managing entity of a core network.
16. The method of claim 15 , wherein the member managing entity is one of a Broadcast Multicast-Service Center (BM-SC), a Serving GPRS Support Node (SGSN) and a Gate GPRS (GGSN).
17. The method of claim 13 , wherein the identifier is an MBMS service IDA and a multicast group ID.
18. The method of claim 17 , wherein the MBMS service ID consists of an access point number (APN) and an IP multicast address.
19. The method of claim 13 , wherein the identifier includes: an MBMS service ID; a multicast group ID; and a multicast area ID.
20. The method of claim 13 further comprising:
attaching another identifier indicative of a kind of a lower service to the multicast data stream.
21. The method of claim 20 , wherein the identifier indicative of a kind of a lower service is an UDP/TCP port number.
