Embodiment Construction

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] figure 1 It shows a flowchart of a flow control method for bearer traffic between intra-office and cross-gateways according to an embodiment of the present invention, which includes the following steps:

[0035] Step S102, calculating the available number of VTIDs between intra-office gateways;

[0036] Step S104, for a call across intra-office gateways, when the softswitch establishes intermediate bearers between intra-office gateways, select gateway pairs according to the available number; and

[0037] In step S106, the available number of VTIDs is allocated on the selected gateway pair, and the traffic carried between gateways in the office is controlled through the allocation of VTIDs.

[0038] Through the above-mentioned VTID allocation, the flow control of intra-office and cross-gateway bearer is realized.

Abstract

The invention provides a loading flow control method used among gateways in a local, which includes the following steps of calculating the usable numbers for the virtual terminal marks among the gateways in the local; selecting a gateway pair according to the useable numbers when a soft exchange sets up an intermediate loading among the gateways in the local for the calling spanning the gateways in the local; and distributing the virtual terminal marks of the usable numbers on the selected gateway pair in the local, thus further controlling the loaded flow among the gateways in the local by the distribution on the number of the virtual terminal marks. The invention also provides a loading flow control device used among the gateways in the local.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a flow control scheme based on IPover E1 (including IP bearer) between intra-office gateways. Background technique [0002] In softswitch marketing, some small and medium-sized operators are unable to build and maintain a large IP bearer network. They hope that after adopting softswitch, they can still use the existing TDM Time Division Multiplexing (TDM) network. Therefore, an IP over E1 solution is provided in the related art to meet the requirements of these operators. [0003] After the IP over E1 solution is adopted on the bearer plane, the voice will be transmitted in the form of cRTP (Compressed Real Time Protocol, compressed real-time protocol). cRTP converts the original 40-byte header (IP (Internet User Datagram Protocol (User Datagram Protocol) head 8 bytes, RTP (Real-time Transport Protocol, real-time transport protocol) head 12 bytes) compressed to ...
