Problems solved by technology

Therefore, when the network environment changes due to factors such as the user’s relocation, if the modem still uses the previous packet cable standard configuration for network registration, the modem will not be able to access the network smoothly.

Embodiment Construction

[0015] Such as figure 1 Shown is the operating environment diagram of the modem in the preferred embodiment of the present invention. In this embodiment, the terminal device 1 communicates with the modem 2 after being started, and accesses the network 4 through the modem 2 and the head-end device 3 to communicate with the network server 5 . The terminal device 1 may be a user terminal such as a computer or an IP phone. The head-end device 3 may be a cable modem termination system (Cable Modem Termination System: CMTS) or a router. The network server 5 can be a network server using MGCP (Media Gateway Control Protocol, Media Gateway Control Protocol) or a network server using SIP (Session Initiation Protocol, Session Initiation Protocol) to communicate according to the different areas where the modem 2 is located.

[0016] Such as figure 2 Shown is the hardware structural diagram of the modem of the present invention. The modem 2 includes a microprocessor 20 , a storage un...

Abstract

A modem is communicated with a network server through a network. the modem comprises: a detection module, which is used to detect whether the network server exists or not through the network when the modem starts; a switching module, which is used to switch a packet cable used by the modem when the network server is detected to be inexistent; a registration module, which is used to register the modem in the network server according to the current packet cable used by the modem when the network server exists. The invention also provides a network registration method of the modem. By using the modem and the method of the invention, the modem can successfully access into the network when a network environment changes.

Description

technical field [0001] The invention relates to a modem and its network registration method. Background technique [0002] The packet cable standard (Packet Cable) used by the modem defines a multimedia network structure in which terminal equipment accesses the network through a modem. The goal is to provide IP-based multimedia services and complete voice over Internet Protocol (VoIP) services. solution. The current mainstream packet cable standards include packet cable standard 1.X (Packet Cable 1.X: PC 1.X for short) and packet cable standard 2.0 (Packet Cable 2.0: PC 2.0 for short), among which PC 1.X includes PC 1.0 and PC 1.5. Two commonly used protocols in the VoIP field are Media Gateway Control Protocol (MGCP) and Session Initiation Protocol (Session Initiation Protocol, SIP). Among them, MGCP is applied to PC 1.X, while SIP is applied to PC 2.0, and The two protocols, MGCP and SIP, are not compatible with each other. [0003] Generally, the network operator will...
