FIELD: radio engineering, communication.SUBSTANCE: invention relates to a method and an apparatus for supporting mobility in a mobile broadcast system and particularly supporting mobility in a mobile broadcasting system which uses an electronic service guide (ESG). The technical result is achieved due to that mobility support is classified in three ways. The first way is to provide roaming information for a local internet protocol data casting (IPDC) operator having a roaming partner among local IPDC operators. In the second way, a terminal transmits a query message for requesting transmission of information on a particular local IPDC operator, and receives information on the particular local IPDC operator in response thereto. The third way is to provide the terminal with ESG type information, an access type of which is classified according to provision of a roaming service. The roaming information, the information on the particular local IPDC operator and the ESG type information, which are provided to the terminal from the mobile broadcasting system, can be provided in an ESG bootstrap level.EFFECT: providing efficient terminal mobility support in a mobile broadcast system.38 cl, 45 dwg, 84 tbl |
