Problems solved by technology

[0007] 1) For the current R99, R4, and R5 networks, a dedicated IP data transmission channel needs to be established between the application server and each UE. Each UE sends a copy of data, so the same service data must be sent multiple times, so the resource utilization rate is very low, and, due to the resource limitation of the network side, the number of access users is also limited
[0008] 2) Due to the wide distribution of NodeB, not all NodeB base stations have the conditions to lay optical fibers or multiple E1s, and even if they are laid, the cost of laying is very high; for operators without transmission resources, the price of renting transmission channels is very high. High
Generally, an operator only provides several live channels (such as several sets of TV programs). If dozens of users under a NodeB in the RAN receive the same service data, such as watching the same TV channel, under the current implementation plan, It is necessary to establish a dedicated transmission channel for each UE on the IUB interface between RNC and NodeB to carry streaming media service data, which will inevitably lead to a large occupation of IUB interface resources, and operators have to increase transmission resources for this. For users, the cost of receiving must be very high
In this way, promoted apps that do not take advantage of the service
[0009] 3) For the R6 network, it has a broadcast multicast-service center (BM-SC, Broadcast Multicast-Service Center), which can theoretically support the multimedia broadcast multicast service (MBMS), but the protocol of this version has not yet been formulated. It will take a long time for mature products to be introduced to the market, and most of the existing networks do not support R6. If R6 is adopted, the overall changes to the existing network will be relatively large
[0010] It can be seen that in the existing network, business data similar to streaming media cannot be multicast, so not only the utilization rate of network resources is low, but also the implementation cost is very high

Embodiment Construction

[0105] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0106] The basic implementation idea of ​​the present invention is that when transmitting service data between the application server and UE, the original point-to-point transmission mode is changed to a point-to-multipoint transmission mode, that is, multicasting of service data is realized.

[0107] Figure 2a Shown is a schematic diagram of an implementation principle of implementing multicast by applying the present invention. A multicast agent module is set in the RAN, and each UE interacts with the RAN and the CN respectively to activate the PDP. Afterwards, the data source used to provide business data only needs to send a copy of all its own business data to the multicast agent module in the RAN through the router, and the existing transmission mode is still used to realize the transmission between the UE and the RAN, that is, every A dedicated data...

Abstract

Key points of the method are as following: setting up multicast proxy module in RAN; the module monitors access request including objective information from UE; when determining that the objective information designated in advance in request is objective information of data source in use for providing service of data operation, the module builds control connection to the UE; in procedure of building control connection, UE obtains information of reception attribute; receiving id of service data content from data source, the module down sends corresponding service data to UE; based on received information of attribute, UE receives service data through built transmission channel. Using multicast proxy module, the invention only needs to transmit one portion of data between data source and multicast proxy module to realize multicast of service data. Features are: fast and smooth data process, and raised use rate of network resources.

Description

technical field [0001] The invention relates to the field of mobile network technology, in particular to a method for realizing multicast service data based on the mobile network. Background technique [0002] With the development of 3G communication technology, the network has been able to provide enough bandwidth for wireless data transmission, and the integration of mobile phones is getting higher and higher, and the information processing capability of mobile phones is getting stronger and stronger. Under this condition, mobile phones have long been It is not only used for traditional voice telephony services, but also can play a variety of service data. Streaming media service data related to video and audio will naturally appear on the mobile phone, such as multimedia short message service data, PS domain video stream Service data, videophone service data, multimedia broadcast multicast service data, etc. [0003] At present, the existing streaming media services play...
