Abstract
The present invention discloses a method for managing multicast subscribers in mobile network, comprising: the data related with multicast traffic is classified into multicast-related record data and multicast route data, wherein said multicast-related record data is stored in the system for query, while said multicast route data is hierarchically stored in the system to determine how to forward multicast data; when a subscriber joins in a multicast group or the multicast subscriber exits the multicast group, said hierarchical multicast route data and said multicast-related record data are modified accordingly, when the multicast subscriber performs position register and position update in network, said hierarchical multicast route data in the system is modified accordingly; in said method, the management of multicast subscribers in mobile network can be achieved and both management efficiency and utilization coefficient of system resources are improved.
