Abstract: A method for upgrading a device through multicast is disclosed. The method includes: monitoring a common channel of a multicast server, where information about all subfiles of a current packaged mirror file is multicast in the common channel; obtaining information about a subfile required for upgrading the device from packets in the common channel, where the information includes an address of a subchannel that bears the subfile on the multicast server; and switching to the subchannel according to the address of the subchannel that bears the subfile required for upgrade, receiving the subfile multicast in the subchannel, and validating the subfile. Further, an apparatus and system for upgrading a device through multicast are disclosed.

Abstract: A method, a system for accessing a home network device, and a home network access device are disclosed. The method includes the steps as follows. A home network access device finds a home network device and obtains information of the home network device through a home network protocol. A data model of the home network device is established in the home network access device according to the information of the home network device. A remote service device accesses the data model of the home network device established in the home network access device through a remote management protocol.

Abstract: A method for acquiring customer premises equipment (CPE) function configuration information includes: setting up a CPE WAN Management Protocol (CWMP) session between an automatic configuration server (ACS) and a CPE; sending, by the ACS, a command to request the CPE to upload the CPE function configuration information to a specified object; and receiving, by the specified object, the CPE function configuration information uploaded by the CPE. An ACS, a CPE, a method for providing CPE function configuration information, and a terminal configuration system are also provided.
