Problems solved by technology

However, it cannot be ruled out that the eMBMS architecture is compatible with 2G / 3G on the wireless side to access the MBMS-GW that only supports the GTP tunneling protocol mode. For example, only the GTP tunneling protocol is supported between the MBMS-GW and the SGSN. There are 2G / 3G access branches directly connected to MBMS-GW
The existing technology does not take into account the need to distinguish between the two cases of whether to support IP multicast transmission at this time.

Embodiment 1

[0090] This embodiment is based on the eMBMS architecture, and the eMBMS architecture supports IP multicast transmission by default. Assuming that the wireless side technology is E-UTRAN and UTRAN, for E-UTRAN and UTRAN that supports IP multicast transmission, the charging message and charging data function (CDF: Charging Data Function) sent by MBMS-GW is generated by MBMS-GW The basic charging unit MBMS-GW-CDR, where CDR is the abbreviation of Charging Data Record, MBMS-GW-CDR must contain IP Multicast and Source addresses (in the text, The IP multicast address and source address should be treated as a parameter) and the public user plane tunnel endpoint identifier (TEID-U).

[0091] Because UTRAN is not excluded as a legacy network element and does not accept IP multicast transmission, at this time, the charging message sent by the MBMS-GW and the MBMMS-GW-CDR generated by the CDF for the MBMS-GW should also include Send user plane data downstream node list information etc. in...

Embodiment 2

[0126] This embodiment is based on the MBMS architecture. It is assumed that in 2G / 3G MBMS services, this embodiment assumes that the BM-SC capability is improved to support IP multicast transmission and header compression, MBMS broadcast is sent from BM-SC to GGSN, and the wireless side technology is UTRAN , Which is sent to UTRAN via SGSN, and then sent to UEs in the service area.

[0127] The MBMS session start request process in this embodiment is as follows Picture 9 Shown:

[0128] Step 901: BM-SC sends an MBMS session start request message to GGSN;

[0129] The MBMS session start request message contains information such as QoS, MBMS service area list, session identifier, estimated session duration, destination network identifier, IP multicast sending flag, and MBMS header compression flag. In this embodiment, after the capability is improved, the corresponding node that supports IP multicast transmission and header compression carries the IP multiple delivery indicator (IP ...

Abstract

The invention relates to a method and a system for distinguishing MBMS (Multimedia Broadcast Multicast Service) user surface data sending modes during charging, which are applied to MBMS and E-MBMS (Enhanced Multimedia Broadcast Multicast Service) network architectures. During the request process for initiating a conversation, a GGSN (Gateway GPRS Support Node) / MBMS-GW (Gateway) allocates IP multicast addresses and source addresses and public TEID-U (Tunnel Endpoint Identifier-User) to downstream nodes; if the downstream nodes receive the IP multicast sending, the GGSN / MBMS-GW carries the IP multicast addresses and the source addresses and the public TEID-U received by the downstream nodes in a charging initiating request and records in a CDR with the charging data function of opened GGSN / MBMS-GW; and if the downstream nodes do not receive the IP multicast sending, the GGSN / MBMS-GW carries a list of the downstream nodes in the charging initiating request and records in the CDR with the charging data function of opened GGSN / MBMS-GW.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and system for distinguishing MBMS user plane data transmission modes during multimedia broadcast / multicast service (Multimedia Broadcast / Multicast Service, referred to as MBMS) charging. Background technique [0002] The MBMS defined in the current 3GPP wireless communication standards organization and the evolved multimedia broadcast multicast service (evolved MBMS, referred to as eMBMS) refer to the use of multicast (Multicast) or broadcast (Broadcast) in the existing wireless communication network. ) Technology establishes the channel of business data, thus completing the business model of distribution from one point to multiple points. For the wireless communication network defined by 3GPP, the wireless access technologies defined by MBMS and eMBMS include GERAN in the 2G period and Universal Terrestrial Radio Access Network (UTRAN) in the 3G period. ) And the ...
