Method and system for counting mbms services

Abstract

The invention discloses a method and system for counting multimedia broadcast multicast (MBMS) services. The method includes: a core network element sends a message to an access network element, and the message indicates whether the MBMS service needs to be counted and / or whether it is available Deactivation: the network element of the access network determines whether to perform the counting and / or deactivation processing of the MBMS service according to the indication in the message. The present invention satisfies various counting requirements of operators for MBMS services, simplifies the implementation process as far as possible, and reduces the complexity of network element processing.

Description

technical field [0001] The present invention relates to the technical field of Multimedia Broadcast Multicast (MBMS, MultimediaBroadcastMulticastService), in particular to a method and system for counting MBMS services. Background technique [0002] In a Long Term Evolution (LTE, Long Term Evolution) system, MBMS services are sent in a Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN, Multimedia Broadcast multicast service Single Frequency Network) manner. The so-called MBSFN method is a multi-cell joint transmission method, that is, cells in a certain geographic location transmit the same MBMS service data on the same time and frequency resources, and the certain geographic location is called an MBSFN area (MBSFNarea). In this way, in the entire MBSFN area, the radio signals corresponding to the data sent from each cell will be superimposed naturally, thereby greatly improving the signal strength. [0003] The relationship between MBSFNarea and cells ...

Problems solved by technology

[0018] For the first requirement above, the existing technology has the following problems: for MBMS services that have not yet initiated a session, the MCE and eNB of the access network have no way to obtain their service identifiers, so they cannot indicate the service identifiers on the radio interface; However, the UE can obtain the service identifier it is interested in receiving through a certain service declaration process; if the access network cannot indicate the service identifier and indicate that the service needs to be "counted" by the UE, then the UE cannot pass it through the service Declare that the learned service identifier is combined with the information indicated by the MCCH, so that the required counting and statistics process cannot be completed

[0021] In the existing message, the core network element (such as BMSC) can indicate whether an MBMS service needs to be counted through the control plane message, but the control plane message triggers the establishment of the bearer of the ground and radio interface at the same time; at the same time, in the existing message There is also no information that clearly indicates whether a service can be deactivated and activated on the radio interface
