201138374 六、發明說明： 【發明所屬之技術領域】 [0001] 本發明涉及纜線數據機，尤其涉及一種纜線數據機支援 多種分組纜線標準的方法。 【先前技術】 [0002] 纜線數據機所使用的標準主要為分組纜線（Packet Cable)標準，該標準定義了 一種藉由高速纜線數據機接 入的多媒體網路結構，其目標是提供基於IP的多媒體服 務，提出網路語音（Voice over Internet Protocol ，VoIP)服務的完整解決方案。分組纜線標準經過多年 的發展，已經形成了多個版本。目前主流的分組纜線標 準有分組纜線標準1. X與分組纜線標準2. 0，其中分組纜 線標準1. X包括分組纜線標準1. 0與分組纜線標準1. 5。 VoIP領域常用的媒體閘道控制協定（Media Gateway Contro 1 Protoco 1，MGCP )應用於分組缓線標準1. X， 而會話初始化協定（Session Initiation Protocol ，SIP )則應用於分組缓線標準2. 0。 [0003] 一般情況下，纜線數據機使用哪種分組纜線標準，運營 商都會根據纜線數據機所在的區域或其他需求在局端伺 服器上統一設置好。這樣，纜線數據機就一定要使用運 營商所設置的分組纜線標準，才能順利接入網路。於是 ，當用戶搬家或其他原因導致局端伺服器上的設置更改 ，則需要更換為使用更改後的分組纜線標準的纜線數據 機，導致入網成本增加與設備的浪費。 【發明内容】 099113625 表單編號A0101 第4頁/共24頁 0992024016-0 201138374 . [0004] [0005] [0006]BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to cable data machines, and more particularly to a method for a cable data machine to support a plurality of packet cable standards. [Prior Art] [0002] The standard used by cable modems is mainly the Packet Cable standard, which defines a multimedia network structure accessed by a high-speed cable modem, the goal of which is to provide IP-based multimedia services, providing a complete solution for Voice over Internet Protocol (VoIP) services. After years of development, the packet cable standard has been formed into multiple versions. The current standard packet cable standard has a packet cable standard 1. X and a packet cable standard 2.0, wherein the packet cable standard 1. X includes a packet cable standard 1.0 and a packet cable standard 1.5. The media gateway control protocol (Media Gateway Contro 1 Protoco 1, MGCP) used in the VoIP field is applied to the packet slow line standard 1. X, and the Session Initiation Protocol (SIP) is applied to the packet slow line standard 2. 0. . [0003] In general, which packet cable standard is used by the cable modem, the operator will uniformly set it on the central server according to the area where the cable modem is located or other requirements. In this way, the cable modem must use the packet cable standard set by the operator in order to successfully access the network. Therefore, when the user moves or other reasons cause the setting change on the central server, it needs to be replaced with the cable data standard using the changed packet cable standard, resulting in increased network access cost and equipment waste.

The DHCP server 54 of the PC 2.0 is a DHCP server that supports the PC 2.0 protocol. All the cable modems designated by the operator using the PC 2.0 standard communication are handled by the DHCP server 54 of the PC 2.0. 099113625 of the terminal Form No. A0101 Page 7 of 24 0992024016-0 201138374 The DHCP server 56 refers to a DHCP server that provides DHCP service to the terminal device 20, and all terminals that access the network 30 by the cable modem 10 The DHCP service of the device is responsible for the DHCP server 56 of the terminal. Referring to FIG. 2, a block diagram of an embodiment of the cable modem 10 of FIG. 1 is shown. In the present embodiment, the cable modem 10 includes a processor 12, a storage medium 14, a transceiver module 100, a determination module 102' replacement module 104, and a registration module 106. By means of the transceiver module 1 , the determination module 1〇2 and the replacement module 104, the cable modem 10 can automatically replace the packet cable standard according to the packet cable standard set by the operator, and make the cable data from the rain. Machine 10 supports a variety of packet cable standards. Thereafter, the cable modem 10 is then registered by the registration module 106. The processor 12 executes the transceiver module 100, the decision module 102, the replacement module 104, and the registration module 106 stored in the storage medium 14 to implement their respective functions. For a detailed description of the specific functions of the above modules, please refer to the description of Figure 3 below. Referring to FIG. 3, there is shown a flow chart of an embodiment of a method for multi-grouping mirror lines of a ridge according to the present invention. The method is used in the ridge line data machine 10 of Figures 1 and 2 and is completed by the functional module shown in Figure 2. [0015] In step S300, the transceiver module 100 broadcasts the DHCP Discover packet to the DHCP server 52 of the PC 1. X, the DHCP server 54 of the PC 2.0, and the DHCP servo of the terminal using _ of various packet cable standards. 56. In step S302, the transceiver module 100 receives a DHCP Of fer packet from one of the DHCP server 52 of the PCI. X, the DHCP server 54 of the PC 2 , and the DHCP server 56 of the terminal. In step S304, the determining module 102 determines whether the DHCP Offer packet received by the transceiver module 100 conforms to the packet cable standard used by the broadcast DHcp Discover packet. 099113625 Form No. A0101 Page 8 of 24 0992024016-0 201138374 . [0016] Here, the DHCP Offer packet conforms to the packet cable standard used by the broadcast DHCP Discover packet, and the DHCP Offer packet includes the configuration file and the 〇ptionl22, and The packet cable standard used by the profile is based on DHCP Discover. Among them, 0ptionl22 is a special field in the DHCP packet specified in DHCP, and the DHCP server 54 for PCI. X, the DHCP server 54 of PC2.0 sends information to the cable modem 1〇. Here, the DHCP Offer packet includes the configuration file and the 〇pti〇ni22 refers to the value that can be read from the DHCP Offer packet order. [0017] In the present embodiment, the DHCP Offer received by the cable modem 10 is intended to include a configuration file using the default packet rule of the cable modem 10 and Opt ion 22 . However, if the default packet cable standard of the twisted data modem is inconsistent with the packet cable standard set by the operator, the DHCP Of fer sent by the terminal's DHCP server 56 will not have the configuration file and Opt ion 22 . Then, the judging module 102 judges that the DHCP 0f er packet received by the transceiver module 100 does not conform to the packet cable standard used by the broadcast]) HCP Discover packet. [0018] If the determining module 1 判 2 determines that the transceiver module 10 0 receives the HCP Offer packet that does not meet the packet cable standard used by the broadcast DHCP Discover packet, then the module 104 is replaced in step S306. The packet cable standard used by the cable modem 10 is changed so that the cable modem 1 can communicate with the corresponding DHCP server. The replacement module 1〇4 switches the cable modem 10 to another operating mode to use another packet cable standard. Thus, when the cable modem of the cable modem 1 is inconsistent with the packet specification standard set by the operator, after one or more replacements, the replacement module 104 can naturally replace its own packet cable standard with 099113625 Form No. A0101 Page 9 of 24 0992024016-0 201138374 Consistent with the packet cable standard set by the operator, so that a variety of packet cable standards can coexist. [0019] In step S308, the transceiver module 100 broadcasts the DHCP Discover packet to the DHCP server 52 of the PC 1.X, the DHCP server 54 of the PC2, and the DHCP server 56 of the terminal using the replaced packet cable standard. . In step S302, the transceiver module 100 receives the DHCP Offer packet from one of the DHCP server 52 of the PCI. X, the DHCP server 54 of the PC 2.0, and the DHCP server 56 of the terminal. In step S304, the determining module 102 determines whether the DHCP Offer packet received by the transceiver module 100 meets the packet cable standard used by the broadcast DHCP Discover packet, and the loop data processor 10 loops through steps S306, S308, S302, and S304. A DHCP Offer packet conforming to the packet rule standard used by the broadcast DHCP Discover packet is obtained. [0020] If the determining module 102 determines that the transceiver module 100 receives the DHCP Offer packet conforming to the packet trunking standard used by the broadcast DHCP Discover packet, the transmitting and receiving module 102 broadcasts the DHCP Request to the PCI. X in step S310. The DflCP server 52, the DHCP server 54 of the PC 2.0 and the DHCP server 56 of the terminal confirm whether the IP address assigned in the DHCP Of fer packet conforming to the packet trunking standard used by the broadcast DHCP Discover packet is occupied. . At this time, the DHCP server 52 of the PCI. X or the DHCP server 54 of the PC 2.0 transmitting the DHCP Of fer packet conforming to the packet cable standard used for broadcasting the DHCP Discover packet will transmit the DHCP Ack packet. In step S312, the transceiver module 102 receives the DHCP server 52 of the PC 1. X corresponding to the packet winding standard used by the DHCP Discover packet, or the DHCP server 099113625 of the PC 2.0. Form No. A0101 Page 10 of 24 0992024016-0 201138374 [0021] 54 receives the DHCP Ack packet and completes the registration according to the received DHCP Ack packet. It should be noted that the DHCP Discover packet, the DHCP Offer packet, the DHCP Request packet, and the DHCP Ack packet are common DHCP service procedures _ common packets, which are in compliance with the DHCP protocol, and therefore will not be described herein. [0024] [0024] [0024] In order to better illustrate the cable modem 10 of the present invention and its method of supporting a plurality of packet cable standards, the steps shown in FIGS. 4 and 5 are given herein.
