Problems solved by technology

[0004] The purpose of the present invention is to provide a method for integrating a multimedia dispatching station in an EPC (Evolved Packet Core: Evolved Packet Core Network) system in an emergency communication scenario, so as to alleviate the EPC system and the multimedia dispatching station equipment from being self-contained, resulting in emergency communication. System integration is difficult and the volume is too large

Embodiment

[0034] Embodiment specifically comprises the following steps:

[0035] Open the / dev / net / tun device through open(" / dev / net / tun", O_RDWR), and then set the attribute of the network device to (IFF_TUN|IFF_NO_PI), use the TUNSETIFF command of ioctl to create a point-to-point virtual network device tun0( 134).

[0036] Create a udp socket, use ioctl's SIOCSIFFLAGS, SIOCSIFADDR, and SIOCSIFNETMASK commands to enable tun0 (134) in socket mode, set its ip to 10.10.10.1, and set its mask to 255.255.255.0.

[0037] Create a udp socket, and use the SIOCADDRT command of ioctl to set a route to the ue (110) network for the multimedia dispatcher in the socket mode. In this embodiment, the ip address of ue (110) is 30.30.0.1, and the mask is 255.255.255.0, so such a backhaul route should be set in the EPC and dispatching platform integrated machine 130: the destination network segment is the data of 30.30.0.0 packet, the next hop should be handed over to tun0(134) for processing.

Abstract

The invention provides a multimedia dispatching station integration method for an EPC system. An all-in-one machine is arranged; an EPC module, a multimedia dispatching station module and virtual network equipment are arranged in the all-in-one machine; when the EPC module starts initialization, initialization of TUN virtual network equipment is increased; an original interface for sending a data packet to the multimedia dispatching station module through a physical link in the EPC module is modified into an interface for sending data through the TUN virtual network equipment; an original interface for receiving the data packet from the multimedia dispatching station module through the physical link in the EPC module is modified into an interface for receiving data through the TUN virtual network equipment; and a core network communication interface in the multimedia dispatching station module is set to the TUN virtual network equipment. The multimedia dispatching station integration method for the EPC system disclosed by the invention is mainly used in an emergency communication scene. Compared with the existing virtual machine integration scheme, the technical scheme disclosed by the invention can save more system resources.

Description

technical field [0001] The invention belongs to the communication field and relates to a method for integrating a multimedia dispatching station in an EPC system. Background technique [0002] Traditional professional trunking communication is often limited to voice communication, which has long been unable to meet the needs of all walks of life for large broadband such as data and video. Since LTE (Long Term Evolution, long-term evolution) has the characteristics of high speed, wide coverage, low delay, high concurrency, high stability, and fast mobility, LTE-based broadband emergency communication has become a consensus in the industry. [0003] Looking at the current LTE emergency communication market, most of the solutions adopt the "bringing principle", using public network LTE base stations (BBU, RRU), small core network, third-party multimedia dispatcher, antenna and other equipment integration. In this solution, each device is self-contained. There are many devices,...
