    Abstract: A method and a subscriber device for implementing an NSP selection. The method includes: when a subscriber device accesses a network, obtaining information of an NAP accessible at current location; when the subscriber device stores the information of NSPs accessible for the NAP, obtaining the information of NSPs accessible for the NAP; otherwise, receiving the information of NSPs accessible for the NAP from the network side; adding the information of accessible NSPs to the information of available NSPs; and selecting an NSP from the available NSPs for a service of the subscriber device. Therefore, extra occupation on air interface resources is lowered, and the time consumption during the network discovering and selecting process is effectively lowered.

    Abstract: A method, system and apparatus are provided for modulation and coding mode used by multicast service macro diversity. A message containing relevant information of modulation and coding mode(s) used by an MBS zone is sent in the MBS zone. The MS receives the message, analyzes other messages in the MBS zone according to the relevant information of the modulation and coding mode(s) contained in this message, and receives MBS service data according to the analyzed result upon other messages in the MBS zone. The invention resolves the problem that an entity is required to uniformly manage the coding and modulation mode definition of each cell in the prior art, as well as the problem that the DCD count in the DL-MAP message has to be continuously tracked in the prior art.
