Problems solved by technology

[0073] The purpose of the present invention is to provide a method for establishing a GTP tunnel in an MBMS multicast service, aiming at solving the problem in the prior art that an uplink GTP needs to be established for each MBMS UE between the SGSN and the GGSN in the MBMS multicast mode. -C tunnel and a downlink GTP-C tunnel, resulting in a waste of TEID resources on the control plane, causing conflicts in the use of GTP-C tunnels by various processes, and making the GTP-C tunnel between SGSN and GGSN in MBMS multicast and broadcast mode Dealing with inconsistencies increases the complexity of system implementation

Embodiment Construction

[0116] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0117] In the present invention, under the MBMS multicast mode, only one uplink GTP-C tunnel and one downlink GTP-C tunnel are established between the SGSN and the GGSN for each MBMS bearer. The SGSN and the GGSN store the IP address and TEID assigned to the GTP-C tunnel by the opposite end in the corresponding MBMS bearer context. Messages related to the MBMS bearer and messages related to the MBMS UE are transmitted over the established GTP-C tunnel.

[0118] As the first embodiment of the present invention, the execution order of each step in the existing activation process is not changed, s...

Abstract

The present invention provides establishing GTP tunnel method in multimedia broadcast / multicasting service. It contains SGSN and GGSN establishing one uplink GTP-C tunnel and one downlink GTP-C tunnel, and utilizing established GTP-C tunnel transmitting MBMS relevant message and MBMS UE relevant message. The present invention saves control surface TEID resource use, avoiding GTP-C tunnel used contradiction, simultaneously make GTP -Cc tunnel processing concordance between SGSN and GGSN in MBMS multicasting and broadcasting mode.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a method for establishing a GTP tunnel in a multimedia broadcast / multicast service. Background technique [0002] Multicast and broadcast are technologies for transmitting data packets from one data source to multiple destinations. With the rapid development of the Internet, a large number of multimedia services emerge, 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 or interactive games. Compared with general data, these multimedia services have the characteristics of large data volume, long duration, and delay sensitivity. Because the mobile network has a specific network structure, functional entity and wireless interface, which is different from the wired IP network, the current IP multicast service is only applicable to the wired IP network, not to the mobile netwo...
