Embodiment Construction

[0057] The main idea of ​​the present invention is that for the same multicast program, the program source of the multicast service is the same, if both RNCs support the multicast service, the data sent by the two RNCs through the data agent is the same, then The DA entity in the DRNC can be used to directly deliver multicast services to the MAC_C entity to solve the problem that SRNC DA data cannot be sent to the DRNC through the public transport channel of the Iur interface.

[0058] Figure 9 is a diagram of the relationship between the control plane and the user plane entity of the embodiment of the present invention. In the figure, it can be seen that the control plane and the user plane channel are separated, the SRNC and the UE perform control plane interaction, and the DRNC uses the data proxy DA The user plane data of the multicast service is delivered to the UE, thereby realizing the establishment process of the public transport channel of the Iur interface of the mult...

Abstract

The invention discloses cross-Iur interface connection holding method for multicast business, wherein when UE into DRNC sub-zone from SRNC sub-zone, building an Iur interface as FP between MAC_D of SRNC and MAC_C of DRNC to load control panel data exchange; using DNRC to send multicast business user panel data through data agent to UE. This invention divides the control entity and user entity, and can keep business data continuity.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a multicast service cross-Iur interface connection maintenance method and DRNC (Drift Radio Network Controller, Drift Radio Network Controller). Background technique [0002] With the improvement of functions and performance, the mobile phone is no longer just a tool for making calls. Its functions in multimedia messaging, video on demand, videophone, mobile TV, etc. can already be supported and applied to a certain extent. According to the information processing capability of the current mobile phone, the effect of watching streaming media on the mobile phone is already satisfactory, plus the bandwidth provided by WCDMA for packet services, it can be said that the realization of multimedia playback on WCDMA is already mature. [0003] At present, the existing streaming media services played on mobile phones all adopt the point-to-point transmission mode, as shown in...
