Method of maintaining the continuity of transmission service and service center

A service center, comprising:

• a content storage unit which stores a transmission service content from a content provider;
• a transceiver which receives a consumption report from a user equipment, currently receiving a first transmission service through a first bearer from a first base station;
• a user database;
• and
• a processor which is coupled to the transceiver, the content storage unit and the user database and configured for:
• in response to the transceiver receiving a specific request, obtaining user identification information of the user equipment currently receiving the first transmission service through the first bearer from the specific request;
• wherein the specific request indicates that the user equipment has been handed over from the first base station to a second base station, and a coverage of the second base station only supports a second transmission service different from the first transmission service;
• accessing the consumption report corresponding to the user equipment based on the user identification information, and obtaining first service information of the first transmission service from the consumption report, wherein the user identification information and the consumption report are stored in the user database;
• and
• controlling the user equipment to switch to use a second bearer to receive the second transmission service according to the first service information, wherein the first bearer is one of a unicast bearer and a broadcast bearer, the second bearer is another of the unicast bearer and the broadcast bearer, the first transmission service corresponding to the first bearer is one of a broadcast service and a unicast service, and the second transmission corresponding to the second bearer is another of the broadcast service and the unicast service.
