Problems solved by technology

[0011] The problem in the prior art is that the notification information of the MCCH modification is only used to notify the start of a new service, so that the UE goes to the MCCH modification boundary to read the modified MCCH content
However, for the MCCH changes caused by the suspension of certain services or other content changes transmitted on the MCCH, the former can only be known by the UE to read or even read the DSI information multiple times to know the unscheduled service data The service has been stopped. For the latter, the UE needs to periodically read the MCCH content of the MCCH modification boundary to know whether the MCCH has changed, so there is no effective mechanism to notify the UE in time
Obviously, the current solution is not conducive to the UE's energy saving and power saving

Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] An embodiment of the present invention provides a method for indicating changes in MCCH content, such as image 3 shown, including:

[0050] Step s301, the network side device generates signaling carrying MCCH content change indication information, and whether the MCCH content corresponding to the MBSFN (Multicast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) area has changed through the MCCH content cha...

Abstract

The embodiment of the invention discloses a change instruction method and an acquisition method, a system and equipment of MCCH (multipoint control channel) content. Compared with the existing technical scheme, change instruction information of the MCCH content is carried in a signaling so that UE (user equipment) can timely know information whether the MCCH content is changed so as to timely receive the modified MCCH content and improve system efficiency; and meanwhile meaningless power consumption of the UE caused by frequently reading an MCCH at MCCH modification boundary is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for indicating changes in MCCH content, an acquisition method, a system and equipment. Background technique [0002] MCCH (MBMS Point-to-Multipoint Control Channel, MBMS Point-to-Multipoint Control Channel) is a point-to-multipoint downlink channel in the eMBMS (enhanced Multimedia Broadcast Multicast Service) system, used for Transmitting control information from the network side to UE (User Equipment, user terminal), this channel is only useful for user terminals receiving eMBMS services. The network side indicates the location information of the MCCH in the BCCH (Broadcast Control Channel, broadcast control channel), so that the user terminal can read the information transmitted on the MCCH according to the indicated location. [0003] The information transmitted on MCCH includes: [0004] (1) eMBMS service information, which is used to indicate the eM...
