Method, device and system for unicast sending broadcast-multicast data

Abstract

The embodiment of the present invention discloses a method for unicast sending broadcast multicast data, including: PGW selects the EPS bearer for transmitting broadcast service according to the first session update request sent by PCRF; PGW acquires IP multicast of broadcast service from BMSC service address, and bind the obtained IP multicast service address with the EPS bearer; the PGW sends a second broadcast service transmission request to the MBMS gateway to make the MBMS gateway send the broadcast service, and according to the IP multicast address of the broadcast service forwarded by the MBMS gateway The broadcast service address searches for the bound EPS bearer, and transmits the broadcast service through the EPS bearer. The technical solution can make full use of network equipment resources, reduce the communication pressure of the GCS application server equipment, thereby reducing the complexity and cost of developing the GCS application server equipment, and meeting the service quality requirements of applications with high real-time requirements.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for unicast sending broadcast multicast data. Background technique [0002] With the development of wireless communication technology, the multimedia broadcast and multicast service has been regarded by the communication industry as a service with very applicable scenarios. Its realization is that the intelligent terminal with video function receives broadcast digital audio and video through channels or channels, etc. content. At present, multimedia broadcast multicast services can already be supported in mobile communication networks. For example, the Long Term Evolution (LTE, Long Term Evolution) system supports multimedia such as mobile phone TV through multimedia broadcast multicast service (MBMS, Multimedia Broadcast Multicast Service) technology. Video broadcasting business. [0003] In MBMS technology, the broadcast multicast se...

Problems solved by technology

However, the above technologies send the broadcast data to the PGW through the interface between the GCS application server and the PGW, which requires high performance of the GCS application server equipment, which increases the complexity and cost of developing the GCS application server equipment.

In addition, according to the existing technology, the unicast transmission of the broadcast service is initiated by the GCS application server, and when the UE repeatedly enters and exits the broadcast service area, a large number of application layer signaling between the UE and the GCS application server or control between the PCRF and the PCEF will be generated. Surface signaling, which makes the process of broadcasting and multicasting services from broadcasting to unicasting less efficient, resulting in delays or data loss in broadcasting services, which cannot meet applications with high real-time requirements, such as emergency rescue, business video conferencing, remote Quality of Service Requirements for Services such as Monitoring
