The invention discloses a method for communication between a session initiation protocol (SIP) client and a mobile phone in a voice over Internet protocol (VoIP) system. The method comprises the following steps that: (1), voice gateway servers regularly report own load conditions to gateway management servers; (2) the gateway management servers store the related information of each voice gateway server in a priority queuing way according to the load conditions; (3) the SIP client transmits a registration message to an SIP server; (4) the SIP server searches for a gateway management server which is closest to the SIP server; (5) the gateway management server allocates a voice gateway server with a light load to the SIP client; (6) the gateway management server extracts the voice gateway server with the light load, and returns the voice gateway server with the light load to the SIP server; (7) the SIP server maintains the related address information of the voice gateway server; (8) the SIP client calls the mobile phone, and successfully establishes a session with the mobile phone; and (9) the SIP client communicates with the mobile phone, and continues the communication or finishes the session. By the method, the communication between a standard SIP client and an ordinary mobile phone can be realized; and the method has the advantages of high stability, high expansibility, load balance and the like.
Description
technical field [0001] The invention belongs to the field of computer network applications, in particular to a communication method between a SIP client and a mobile phone in a VoIP system. Background technique [0002] A Session Initiation Protocol (SIP for short) is widely used in a Voice over Internet Protocol (VoIP for short) system. However, the vast majority of existing VoIP systems only support communication between SIP clients, and most of the few VoIP systems that support communication between SIP clients and mobile phones also have poor scalability and heavy node loads, which cannot meet the needs of large networks. Requirements for concurrent calls of large-scale users. Contents of the invention [0003] The purpose of the present invention is to provide a method for communicating between a SIP client and a mobile phone in a VoIP system. The method can realize communication between a standard SIP client and an ordinary mobile phone, and can support concurrent c...
