A method, an apparatus, and a system for generating and verifying a color barcode are provided. The method for verifying the color barcode is adapted to an electronic apparatus to execute verification with use of a color barcode certificate. In the method, direction information of a plurality of boundaries among a plurality of serially connected symbolic elements in the color barcode certificate is read to retrieve first authentication information of a first party. Each of the symbolic elements is one of at least two polygons, and colors of adjacent symbolic elements are different. Color information of the symbolic elements is then read to retrieve second authentication information of a second party. An identity of a holder of the color barcode certificate is verified according to the first authentication information and the second authentication information.

Method, apparatus and system for generating and verifying color barcode

A method for an access service network gateway (ASN-GW) to provide multicast and broadcast services (MBSs) through a plurality of base stations (BSs) in an MBS zone. The method includes: generating a plurality of synchronization maps (SYNC MAPs) including synchronization information for the BSs to generate MBS data frames; and transmitting to the BSs the generated SYNC MAPs, one in each of a plurality of schedule intervals.

System and method for multicast and broadcast service synchronization

A method for providing a multicast and broadcast service (MBS) by transmitting a plurality of data frames in a wireless network. The method includes: generating a first MBS data information element (MBS-DATA-IE) in a first one of the data frames, the first MBS-DATA-IE including information relating to a logical channel of the MBS, and indicating a location of an MBS map (MBS-MAP) in a second one of the data frames; determining ones of the data frames between the first and second ones of the data frames in which to add a plurality of extra MBS-DATA-IEs; and generating the extra MBS-DATA-IEs, the extra MBS-DATA-IEs being generated in the determined ones of the data frames and including information relating to the logical channel.
