[Prior Art] FIG. 1 depicts a schematic diagram of a wireless local area network in the prior art, which includes: a station 101-1, a station 101-2, and a station 101-3. Before the stations iou, 101-2, and 101-3 can communicate with each other, there must be an agreement between the stations, which agreement is about the meaning of the signals transmitted by the stations. For example, the stations must agree on who sends the message, when it constitutes a "0", and a "1", how to detect and correct an error, and so on. In the language of telecommunications, this agreement is called a communication protocol (pr0toc1). In a local area network, a communication channel is shared between stations. If more than one station transmits messages simultaneously through the shared channel, the messages will be lost. Therefore, a LAN protocol must include a mechanism to ensure that only one station can access the shared communication channel at a time. Mechanisms known as Medium ACcess Contr0 may also provide additional services such as encryption, authentication, and quality of service (q0s) provisioning, as well as the management of specific non-communication functions, such as power conservation operations Conserving operational state). [Summary of the invention] Media access control is theoretically the same as used to control entity (ie, radio) messages in a benefit line area, or, or a line that meets the standards of the Institute of Electrical and Electronics Engineers (ΙΕΕΕ) 802 · 丨 丨. The mechanism of signal transmission and reception (in this specification, the local bureau A regards 85884 200423633 as " continuous control) is incompatible & &. ^,,, ~ 々 'but in fact these two Mechanisms are inevitably interwined. The invention can separate the media access control from the physical control part. The opposite 802.11 wireless network is particularly advantageous. The potential Q is the standardization, development, and realization of certain media access services that are independent of entity control, while still maintaining the existing 8021. The installed tables in the equipment are fully compatible. This separation can save tens or hundreds of millions of dollars for semiconductor, computer, and networking companies. In particular, the descriptive embodiments implement media access control services by dividing them into & media access control services that are not governed by entity control. Media access control and The media access control service under the control of media access control is used to make certain media access control services out of physical control. Although in this description, the descriptive embodiment is to delete the related text of 802.n LAN (referred to as disclosed), the person in the bank will still clearly understand how to use communication protocols other than IEEE P80.2.15.3, etc.) make and use alternative embodiments of the present invention, including wired and wireless networks. The illustrative embodiments include: receiving a service data unit in the upper-layer media access control; And output the-communication protocol data unit to the lower-level media access control; wherein the communication protocol data unit is based on the following: (a) the first time of the service and (ii) the first-the media access control service, the first The media access control service is not subject to-providing services to the underlying media access control "& control" status; and wherein the underlying media access control 85884 200423633 k is for a second media access control service, the second The media access control service is based on: the communication protocol data unit, and (ii) the state of the entity control. [Embodiment] FIG. 2 depicts a wireless network according to the prior art. The conceptual architecture diagram of station 1〇1_ 丨. As shown in Figure 2, the rank line station 101_ 丨 contains logical link control 21, media access control 220, and entity control 230. The interconnections are as shown in the figure. The logical link control (LC) 210 performs various tasks, such as packet multiplexing from multiple network layer entities and decapsulating the packets into multiple network layer entities, along with the access of the lower layer media access control plus the physical layer. Provided single-data link to carry out the materials of these packets, and establish and maintain logical link connection through the shared data link, and / or provide confirmation notification of the counter message, on behalf of those who need such connection direction or confirmation notification. The network communication protocol of the connection service is well known in the art. The media access control 220 performs a channel access function, which ensures that only one station can upload signals to the shared communication channel at a time, and Frame addressing and detection, frame inspection, frame generation, and inspection, as well as logical link control protocol data army, Dengping 1 limit. In addition, media access control Additional services can be provided, including additional services, authentication, authentication, and service quality provision, as well as examples of related power management functions such as communication, non-communication, etc., as is well known in the art. Such as radio, Ethernet And the entity receiving 230 from other stations to the signal entity control 230 performs the physical reception of the physical transmission of signals to other stations via network media (eg, etc.), as is well known in the art. 85884 200423633 Figure 3 is a specific implementation of the present invention The example describes the conceptual architecture of a wireless station. As shown in Figure 3, the media access control 220 is separated into an upper media access control 3 1 0 and a lower media access control 320. The upper media access control 3 1 0 Provides a subset of media access control services that are not subject to entity control 230. These media access control services include transmission queues, additions, decryption, authentication, association (assassocia), re- Association, scanning, distribution, and traffic categorization (the purpose of which is to exemplify, but not limited to, quality of service (qOS) provisioning), is well known in the art. Upper-layer media access control can also perform those functions within the scope of media access control data services and media access control management services that are not subject to physical control, including power management, queue management, and dual detection (dupUcate detecti〇n) and filtering, splitting, splitting, queue management. The lower layer media access control 320 provides maintenance media access control services (that is, those services that depend on the entity control 230), including channel access, receipt confirmation (such as frame control sequence, forward error correction (fault) to correction ), Etc.), and those services that include hardware real-time functions and / or physical layer implementations, such as response control (such as clear to transmit [cts], acknowledge notification [ACK], etc.), as is well known in the art. There are four criteria for judging which functions belong to the lower layer: touch A π i, ^ ^ ㈢ m access control 320: i for a given physical layer or a given meeting s, ~ ~ ⑤ functions of a specific layer type; ϋ Requires knowledge of the internal state of the physical layer or the remaining two sulphur + ^, which 4 g body layer realizes the function of specific operational characteristics knowledge; 85884 200423633 iii Use 糸 to generate the corresponding communication (transmission) that can be seen on the media Signal) sequential hardware real-time functions; and iv other specific functions in the underlying media access control, for reasons of general implementation considerations, or because of-having sufficient influence-parties (such as Microsoft, etc.) want to be in the underlying media There are other specific functions in access control. As shown in FIG. 3F, the upper layer media access control 31 outputs data to the lower layer media access control 320 via the path 311, and receives data from the lower layer media access control 320 via the path 312. Similarly, the lower-layer media access control 32 outputs the shell material to the entity control 23 via the router 221, and receives data from the entity control 230 via the path from the entity control 230.
