Embodiment Construction

[0032] Please refer to figure 1 , figure 1 It is a schematic diagram of a physical layer device 10 for remotely controlling physical layer functions according to an embodiment of the present invention. The physical layer device 10 is used for remote control of physical layer functions with a remote physical layer device, and includes a receiving unit 101 , a first judging unit 102 , a second judging unit 103 , a control unit 104 and a processing unit 105 . When the physical layer device 10 receives a received packet PK_rcv from a remote physical layer device, the receiving unit 101 receives the received packet PK_rcv. The first judging unit 102 checks the encoding of the received packet PK_rcv received by the receiving unit 101 according to a packet format PKFT to generate a first judging result DRE1. The second judging unit 103 judges the identity of the received packet PK_rcv according to the packet format PKFT to generate a second judging result DRE2. Next, the processin...

Abstract

The invention relates to a remote control method for a physical layer of a local terminal, which comprises the following steps of: receiving a receiving packet; according to a packet format, judging the code of the receiving packet so as to generate a first judgment result; according to the packet format, judging the identity of the receiving packet so as to generate a second judgment result; according to the first judgment result and the second judgment result, discarding the receiving packet, or according to the packet format, unscrambling the receiving packet so as to generate unscrambling data; and according to the unscrambling data, controlling the function of the physical layer.

Description

technical field [0001] The present invention relates to a remote control method and related devices, in particular to a method for remotely controlling physical layer functions of a physical layer and related physical layer devices. Background technique [0002] According to the specifications defined by the International Organization for Standard (ISO), the open system connection mode is a seven-layer communication structure, including a physical layer (Physical Layer), a link layer (Link Layer) from bottom to top. ), a network layer (Network Layer), a transport layer (Transport Layer), a session layer (Session Layer), a presentation layer (Presentation Layer) and an application layer (Application Layer). In a communication device, the physical layer detects and receives packets, and then upper layers (such as link layer and network layer) interpret the contents of the packets. In general, a packet usually includes user data and control parameters of each layer. [0003] ...
