Embodiment Construction

[0032] The invention provides a method and system for sending multicast broadcast information, which are applied in the technical field of communication. The main ideas of the method and system are as follows: designate the time required to send the data packet; send the data packet to the base station; and when the time arrives, the base station sends the data packet. The method and system solve the problem of multicast broadcast service synchronization between base stations, and ensure that different base stations in the same multicast broadcast area can send the same multicast broadcast information at the same time at any time.

[0033] Please refer to FIG. 1 , which is a structural diagram of a system for sending multicast broadcast information according to the present invention, including a content distribution source 200 and a base station 100 .

[0034] The content distribution source 200 is configured to send the data packet to the base station 100, and specify the tim...

Abstract

The invention discloses a method and system for sending the multicast broadcast message and is applied in the communication technology area, the described method includes the following steps: (p1) specify the distribution tie of the data packet; (p2) send the data packets to the base station; (p3) the base station distributes the data packets after a period. The system includes contents distribution source and base station, content distribution source is used to send the data packets to the base station and specify the distribution time of the data packets. The base station is used to distribute the data packets in the specified time. The invention can solve the synchronization problems of the multicast broadcast service between the base stations and can guarantee that different base stations in one multicast broadcast area can send same multicast broadcast message at any time, so it can better support the macro sub-set.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for sending multicast broadcast information. Background technique [0002] Most of the current wireless network design adopts the structure of the cell, and the users of the cell complete the communication through the base station. In order to ensure the continuity of user communication, adjacent cells overlap each other. When a user crosses different cells, in order to maintain the quality of continuous communication, the user needs to request a channel from an adjacent cell, and this process is called handover. Diversity reception is to receive signals carrying the same message with little correlation on several branches, and select or synthesize each signal through combining technology, so as to reduce signal fading caused by factors such as terrain undulations, buildings and obstacles. the impact caused. In the process of handover, the mo...
