Abstract: An aspect of the disclosure includes a method for adjusting a multicast broadcast service area. According to an exemplary embodiment, the method may include, but is not limited to, the following steps. A cell list in a session update request message is obtained. An old broadcast target area for a multicast broadcast service is adjusted to a new broadcast target area for the multicast broadcast service according to the cell list. At least one base station is controlled to allocate or release radio spectrum resources for the multicast broadcast service.

Abstract: An application service server, a region-based information processing method, and user equipment are provided. In the method, an initial message is received, identification information is determined according to the location information of the initial message, and a preprocessed message is generated. The initial message includes a notification content corresponding to the location information, and the location information is defined by a geographic coordinate system. The identification information is provided by a geographic information service. The preprocessed message includes the notification content and the identification information.

Abstract: A vehicle information distributing method is provided, including: receiving a plurality of first vehicle information from a first base station to determine a first service area; receiving a plurality of second vehicle information from a second base station to determine a second service area; calculating a forwarding area based on a distance or an intersection between the first service area and the second service area; transferring the first vehicle information within the forwarding area to the second base station, and transferring the second vehicle information within the forwarding area to the first base station; and broadcasting, by the first base station, the second vehicle information from the forwarding area, and broadcasting, by the second base station, the first vehicle information from the forwarding area.

Abstract: Provided are a broadcast multicast service center and a method applicable to a multimedia broadcast multicast service (MBMS) broadcast service management. The method includes: monitoring a service connection of a V2X between an application server and user equipment to generate a resource merging instruction when the service connection has no network traffic; searching for other service resources that are currently being executed and can share a service according to the resource merging instruction; analyzing the other service resources and the service connection through quality of service parameter screening and a broadcast service area comparison to determine a selected service resource from the other service resources; and adjusting a scheduling period of the service connection to be smaller than a scheduling period of the selected service resource to enable subsequent network traffic packets of the service connection to share network traffic of the selected service resource.
