Problems solved by technology

[0011] When expanding capacity through multiple SBCs, it is necessary to change the original network and modify the configuration of the softswitch. At the same time, the configuration is complicated and error-prone. Moreover, this expansion method is inconvenient. Each time an SBC is added, the configuration may be modified globally to expand sex is also relatively poor

Embodiment 1

[0040]see figure 2 , this embodiment provides an interworking gateway system, including: SDD and multiple SBCs;

[0041] Among them, SDD is used to select an SBC from multiple SBCs, modify the target address of the call packet sent by the source softswitch device to the address of the selected SBC, and send the call packet after the modified target address to the selected SBC ; It is also used to receive the call message after the address information is converted by the selected SBC, modify the source address of the call message after the address information is converted to its own service address, and send the call message after the source address is modified to the destination softswitch device ;

[0042] SBC is used to find the mapping relationship corresponding to the target address in the call message after receiving the modified target address sent by SDD, and convert the call message after modifying the target address according to the mapping relationship Address inf...

Embodiment 2

[0049] This embodiment provides an interworking gateway system, including: SDD and multiple SBCs; in order to balance the load on each SBC, see Figure 4 , SDD specifically includes:

[0050] The remaining capacity calculation module is used to receive the remaining resources reported by the SBC, and calculate the remaining capacity of the SBC according to the remaining resources reported by the SBC; wherein, the remaining resources include remaining call volume, remaining CPU, remaining memory and remaining weight;

[0051] The second session border control device selection module is configured to select an SBC from multiple SBCs according to the remaining capacity calculated by the remaining capacity calculating module.

[0052] The second address conversion module is used to modify the target address of the call packet sent by the source softswitch device to the address of the SBC selected by the second session border control device selection module, and send the call packe...

Embodiment 3

[0087] see Figure 5, this embodiment provides a signaling distribution device, including:

[0088] A selection module, configured to select a session border control device from a plurality of session border control devices;

[0089] The target address modification module is used to modify the target address of the call message sent by the source softswitch device to the address of the session border control device selected by the selection module, and send the call message after the target address is modified to the selected session border control device equipment;

[0090] The source address modification module is used to receive the call message after the converted address information sent by the session border control device selected by the selection module, modify the source address of the call message after the converted address information to its own service address, and send the call message to the destination softswitch The device sends the paging packet with the so...

Abstract

The invention discloses a communicated gateway system, equipment and a service agent method, belonging to communication field. The system comprises a SDD and a plurality of SBCs. The SDD comprises a selection module, a destination address modifying module, and a source address modifying module; the SBC includes a mapping relationship searching module and a conversion module. The method comprises modifying the destination address of a calling message into the address of a selected SBC, and transmitting the calling message to the SBC; searching the mapping relationship corresponding to the destination address in the calling message when the SBC receives the calling message, converting the address information of the calling message according to the mapping relationship, and transmitting the calling message having converted address information to the SDD; and modifying the source address of the calling message by the SDD to the service address of the SDD, and transmitting the calling message to a destination soft switch equipment. The invention achieves the capacity-expansion problem of communicated gateways, and has convenient and flexible expansion.

Description

technical field [0001] The invention relates to the communication field, in particular to an intercommunication gateway system, equipment and service agent method. Background technique [0002] With the development of IP (Internet Protocol, Internet Protocol) technology, the telecommunication network, computer network and cable TV network will eventually be unified into the IP network, and it has been agreed by everyone to carry voice, data and video through the public packet network. Under the trend of service-driven and network convergence, NGN (Next Generation Network, Next Generation Network) based on softswitch technology emerges as the times require. [0003] With the wide application of NGN, various enterprises begin to deploy VoIP (Voice over IP, Voice over IP) on a large scale. focus on. As a session border controller, the SBC provides a necessary channel for all information flows and media flows entering or exiting the network. [0004] SBC is usually deployed a...
