Call processing method, system and device

Abstract

A method, a system and a device for call processing are disclosed in the embodiments of the present invention. The call processing method includes: obtaining, by a call initiator, address information of all or part of call managers in a network domain that processes a call, where the all or part of the call managers include a call manager that processes the call and is adjacent to the call initiator; sending, by the call initiator, a first call creating request message to an adjacent call manager according to the address information of the all or part of the call managers; and receiving, by the call initiator, a first call creating response message from the adjacent call manager. Through the embodiments of the present invention, in the case that a service at a client side is required to be sent through multiple networks at a server side, inter-domain link selection and admission control may be implemented through section call processing.

Description

technical field [0001] The present invention relates to the communication field, in particular to a call processing method, system and device. Background technique [0002] In the communication network, users can connect their devices through the connection service provided by the operator's network. For example, the user can connect two routers through the optical connection service provided by an optical network operator. When the control plane is introduced into the network, the control plane defines common protocols, which can realize rapid and automatic creation of user services. The protocol includes two parts: call and connection. The call is used to implement functions such as authentication of user access rights and exchange of link information on the user side. The connection mainly realizes the provision of user services, that is, resource allocation and reservation in the operator network . [0003] see figure 1 , is a schematic diagram of a call model in the ...

Problems solved by technology

[0007] In the process of implementing the present invention, the inventor finds that the existing call model has at least the following disadvantages: the existing General Multi-Protocol Label Switching (GMPLS, General Multi-Protocol Label Switch) call model only supports end-to-end call processing. When the connection business passes through multiple service-side networks (assuming that each service-side network is divided into one domain), the existing call model does not support the segmentation processing of the call by each domain, so it does not support inter-domain link selection and each domain. Domain access control and other functions
