Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and the embodiments.

[0033] figure 1 Shows a flowchart of a flow control method for intra-office cross-gateway bearer according to an embodiment of the present invention, which includes the following steps:

[0034] Step S102: Calculate the available number of VTIDs between intra-office gateways;

[0035] Step S104, for calls across intra-office gateways, the softswitch selects gateway pairs according to the available number when establishing an intermediate bearer between intra-office gateways; and

[0036] Step S106: Allocate an available number of VTIDs on the selected gateway pair, and then control the intra-office cross-gateway traffic carried by the VTID allocation.

[0037] Through the above VTID allocation, the flow control of the intra-office cross-gateway bearer is realized.

[0038] Calculating the available number can include the following steps: calculate the v...

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 field of communications, and more specifically, to a flow control scheme based on IPover E1 (including IP bearer) between intra-office gateways. Background technique [0002] In the softswitch market promotion, there are some small and medium-sized operators who are unable to build and maintain a larger IP bearer network. They hope that the existing TDM time division multiplexing (Time Division Multiplexing) network can be used after the softswitch is adopted. Therefore, an IP over E1 solution is provided in related technologies to meet the needs of these operators. [0003] After adopting the IP over E1 solution on the bearer plane, the voice will be transmitted using cRTP (Compressed Real Time Protocol, compressed real-time protocol), cRTP will be the original 40-byte header (IP (Internet Protocol, Internet Protocol) header 20 bytes, UDP ( User Datagram Protocol (User Datagram Protocol) header 8 bytes, RTP (Real-time Tr...
