Problems solved by technology

Although this method prevents the multimedia server from sending service data separately to the user equipment in the mobile communication subnet, the data is still transmitted in unicast mode between the multimedia server and the gateway, and the transmission optimization between the multimedia server and multiple gateways is not considered. The same data sent to multiple gateways is repeatedly transmitted in the IP network between the multimedia server and the gateway, see figure 2
This results in a waste of IP network bandwidth resources, increases the load on the multimedia server, and affects the number of gateways that the multimedia server can support, that is, its scalability
Moreover, with the rapid development of multimedia enhanced services and the increase in the number of mobile communication subnets using the same service, the impact of the above defects on network bandwidth resources and scalability continues to increase

Embodiment 5

[0066] Below in conjunction with the accompanying drawings, the embodiment of the application of the technical solution of the present invention in Multimedia Broadcast / Multicast Service (MBMS for short) will be further described in detail.

[0067] MBMS is a point-to-multipoint service that provides a data source to send data to multiple users in a mobile network, and is used to effectively realize network resource sharing (including mobile core network and access network resource sharing). MBMS is based on the existing WCDMA or GSM communication network, by adding some new functional entities such as Broadcast Multicast Service Center (Broadcast Multicast Service Center, referred to as BM-SC), and in the existing network functional entities in the packet domain such as service GPRS Support Node (Serving GPRSSupport Node, referred to as SGSN), Gateway GPRS Support Node (Gateway GPRS Support Node, referred to as GGSN), Radio Network Controller (Radio Network Controller, referre...

Abstract

The invention discloses a moving communication network multimedia enhancing business realizing method, which comprises the following steps: step2, user device applies to use multimedia enhancing business from moving communication subnet; step2, the gateway of moving communication subnet adjusts if the gateway joins in the corresponding IP multicast set, if yes, the step6 is carried out; if not, the step3 is carried out; step3, the gateway sends registration request message to multimedia server; step4, the multimedia server sends registration request response message to gateway; step5, if the multimedia server agrees the gateway use the business, the gateway sends admission IP multicast set information to IP multicast set, if not, the step6 is carried out; step6. The gateway sends response message to user device; step7, the multimedia server sends multimedia enhancing business content to gateway in IP multicast mode; the gateway is sent to the user device by moving communication subnet.

Description

technical field [0001] The invention relates to a method for realizing a multimedia enhanced service in a mobile communication network, in particular to a method for realizing a multimedia enhanced service in a mobile communication network that can effectively save bandwidth, improve the utilization rate of network equipment and media resources, and enhance scalability. Background technique [0002] With the rapid development of mobile communication, users' demand for communication is no longer satisfied with telephone and message services, and a large number of multimedia services have emerged, some of which require multiple users to receive the same data at the same time, such as video on demand, TV broadcast, Video conferencing, online education, interactive games, etc. Compared with general data, these mobile multimedia services have the characteristics of large data volume, long duration, and delay sensitivity. In order to realize multicast and broadcast of plain text ...
