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 method of receiving an MBMS service from a network, the method comprising:
performing a subscription procedure with the network to allow the user to receive an MBMS service among a plurality of MBMS services;
receiving a service announcement that informs about the plurality of MBMS services to be provided and related information regarding at least one of multicast service identification and address information;
performing a joining procedure in order to receive the MBMS service;
receiving a service notification that informs about the MBMS service to be transmitted from the network; and
receiving the MBMS service from the network, wherein the MBMS service includes MBMS data units having the MBMS ID attached thereto, wherein the MBMS ID is used to distinguish between MBMS services.
2. The method of claim 1 , wherein the MBMS service is received according to different multicast areas or quality of service (QoS) requirements.
3. The method of claim 1 , wherein the network is a UTRAN.
4. The method of claim 1 , wherein the MBMS ID is related to channels for the MBMS services.
5. The method of claim 1 , wherein the MBMS ID is related to at least one of a group ID, an IP address, service areas, and quality of service (QoS).
6. The method of claim 5 , wherein the group ID is used for MBMS service identification.
7. The method of claim 5 , wherein the MBMS ID is represented by an access point number.
