[0047] The present disclosure provides a transmission method. FIG. 1 is a flowchart of the transmission method according to an embodiment of the present disclosure. As shown in FIG. 1, the method comprises the following steps.

[0048] In step 101, one or more customer signals are transmitted in a first channel based on a first container with a first length, a payload part of the first container being used to carry the one or more customer signals; wherein the first container takes an S code block as a container start, and the S code block includes an overhead part of overhead information used to carry the one or more customer signals.

[0049] In the embodiments of the present disclosure, the transmission method can be executed by a transmission device. The transmission device can be a device capable of signal sending, such as a sending device, a sending-end device, a transmitting-end device, a source-end device, a source device, a transmitting-end device, a transmitting device, a sending node, a sending-end node, a transmitting-end node, a source node, a transmitting-end node, a transmitting node, a transmitting end, a source end, etc. Alternatively, the transmission device can also be a device capable of signal receiving, such as a receiving device, a receiving-end device, a receiving-end device, a sink-end device, a sink device, a receiving node, a receiving-end node, a receiving-end node, a sink node, a receiving end, a sink end, etc.

[0050] In some embodiments, the transmission method can be performed by a network device or a terminal.

The terminal is a device that provides voice and / or data connectivity to a user, and can be a handheld device having wireless connection capability, a vehicle-mounted device, and the like. Examples of the terminal include a mobile phone, a pocket personal computer (PPC), a palmtop computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, and a vehicle-mounted device.

[0051] In the embodiments of the present disclosure, the client can also be referred to as a service, a client, and the like. The client signal can also be referred to as a service signal, data, a signal, a client service, client data, a client signal, service data, a service signal, a client signal, a client service, client data, and the like. The above names can be equivalent or replaced as needed.

[0052] In the embodiments of the present disclosure, the one or more client signals can be client signals of the same service type or not passing through the service type, and can come from different clients, for example, a plurality of clients are opened different bandwidths of dedicated lines, and the client signals of the plurality of clients are transmitted in the first channel through the first container.

[0053] In the related art, a fixed bandwidth service is byte bit stream coding, and a fine-grained channel (for example, fgMTN) is based on a 64B / 66B code block stream consistent with the Ethernet bottom layer, therefore, the fixed bandwidth bit stream cannot be directly filled into the fgMTN channel, and needs to be container encapsulated, rate adapted, and the like. Different fixed bandwidth services and different fgMTN pipes have different rate differences, which will cause that for different types of fixed bandwidth services, the required container cannot have the same length. In the embodiments of the present disclosure, a first container with a fixed length can be used to transmit a client signal in a first channel, the first channel can include at least a fine-grained (fg) channel, and / or the client signal can include at least a signal corresponding to a fixed bandwidth (CBR) service. It can be understood that the embodiments of the present disclosure can define a container with a uniform length, that is, a first container with a first length, for different types and bandwidths of fixed bandwidth services in the fine-grained channel. For example, the fine-grained channel is a fine-grained MTN slice channel (fgMTN).

[0054] The first container takes an S code block as the beginning of the container, and the S code block is, for example, a 66-bit length start code block. FIG. 2 is a schematic diagram of a code block format of 64B / 66B coding in the related art. As shown in FIG. 2, a sync head (sync) 01 represents a code block (Data Block) carrying pure data, and a sync head 10 represents a code block (Control Block) carrying mixed data / control information. The 8 bits (bits) next to the sync head in each control block are a type field, for example, “0x1E”, “0x78”, and the like in FIG. 2, and the following 56 bits are control information or data information or a mixture of the two. For a data block, the following information is (8*8=) 64-bit data; for a pure control (type field is 0x1E) control block, the following information is an 8-bit type indication and (7*8=) 56-bit control information. In FIG. 2, C represents a control code, each control code is 7 bits; D represents a data code, each data code is 8 bits; S represents the beginning of a packet, and T represents the end of a packet. S can only appear in the 0th and 4th bytes of 8 bytes, and T can appear in any byte.

[0055] In some embodiments, referring to FIG. 2, the format of the S code block is "S0D1D2D3D4D5D6D7", and the S code block is composed of 7 data codes of 8 bits, in addition to a 2-bit synchronization header (10) and a type indication filled with "0x78" in the first byte. In the embodiments of the present disclosure, the multiple byte positions (up to 56 bits) after the S code block can be used to carry the overhead information of the one or more customer signals. For example, the 7 bytes after the S code block can be filled with overhead information.

[0056] In the embodiments of the present disclosure, the overhead information can also be referred to as overhead, overhead (OH), etc., and the above names can be equivalent or replaced as needed.

[0057] In some embodiments, the customer signal is filled into the payload part of the first container by using a generic mapping procedure (GMP). It can be understood that the embodiments of the present disclosure fill the one or more customer signals into the payload area of each first container by using the GMP filling method while maintaining the length of the first container as the first length.

[0058] As an example, the filling method of the generic mapping procedure can use a Sigma / Delta algorithm to uniformly fill stuff bytes in the customer signal.

[0059] It should be noted that in the embodiments of the present disclosure, the payload can also be referred to as payload, payload (or PLD), etc., that is, the payload of the first container can also be referred to as the payload of the first container or the payload (PLD) of the first container, and correspondingly, the payload part can also be referred to as the payload area, the payload area, or the payload area, that is, the payload part of the first container can also be referred to as the payload area of the first container, the payload area of the first container, or the payload area of the first container, and the above names can be equivalent or replaced as needed.

[0060] The transmission method of the embodiments of the present disclosure carries various fixed-bandwidth customer signals in the first channel by using a first length of fixed length, solves the problem that a fixed-bandwidth bit stream cannot be directly filled into an fgMTN channel, and based on the first container of fixed length, the consistency of the first container and the overhead can be achieved in various channel bandwidths, various fixed-service bandwidths, and various numbers of customer signals, and the bandwidth utilization is improved.

[0061] In some embodiments, the overhead information is jointly carried by the overhead portions included in the plurality of first containers. In some embodiments, in order to ensure bandwidth utilization, in addition to the service bandwidth, the bandwidth utilization is reduced as much as possible by the overhead and the like, the overhead group can be formed by the overhead portions included in the plurality of first containers, and the same group of overheads, such as the overhead information of the same customer signal, can be carried in the form of the overhead group.

[0062] In the related art, the proportion of the overhead information affects the bandwidth utilization. For the case that the service bandwidth and the fgMTN channel are relatively close and the bandwidth is relatively tight, all the information cannot be accommodated in the container overhead. The embodiments of the present disclosure can jointly carry the overhead information of the customer signal by the overhead portions of the plurality of first containers, so as to improve the bandwidth utilization.

[0063] For example, the overhead portions of N first containers can be taken as an overhead group, and the N first containers jointly carry a group of overhead information. Wherein, N can be an integer greater than 1.

[0064] In some embodiments, the overhead portion of the first container includes a first field, and the first field corresponding to each of the plurality of first containers is used to identify part of the overhead information of a customer signal. For example, the overhead portion of the first container in the S code block can carry an overhead group number (i.e. the first field) used to identify the overhead group, so as to form a complete overhead group by the overhead group numbers carried by the plurality of first containers.

[0065] For example, the first field can be used to identify the order of the overhead portion of the corresponding first container when forming the overhead group. By the first field of each of the N first containers, the overhead group used to carry a group of overhead information can be formed in order.

[0066] FIG. 3 is a schematic diagram of the first field included in the overhead portion of the first container according to an embodiment of the present disclosure. As shown in FIG. 3, the length of the first container is fixed as a first length, and the S code block is taken as the container start, the customer signal is filled into the payload of the first container, and the overhead portion of the S code block includes an overhead group number (i.e. the first field). The overhead portions of the three first containers in FIG. 3 jointly form an overhead group, and the overhead group is formed by the overhead group numbers “01”, “10” and “11”, and jointly carries the overhead information of the customer signal in the figure.

[0067] In some embodiments, the length occupied by the first field can be determined according to the number of the first containers corresponding to one overhead group.

[0068] In some embodiments, in the case of transmitting a plurality of customer signals in the first channel, the number of the first containers (such as N) corresponding to the overhead group associated with each customer signal is fixed.

[0069] In some embodiments, the overhead information corresponding to each of the one or more client signals is carried by the overhead portions included in the one or more first containers associated with each of the one or more client signals; wherein the overhead portion of each of the one or more first containers includes a second field, which is used to identify the overhead information of the corresponding client signal in all the overhead information of the one or more client signals.

[0070] In the embodiments of the present disclosure, the overhead portions included in the one or more first containers associated with each of the one or more client signals form an overhead group corresponding to the client signal, which is used to carry the overhead information of the client signal; and the overhead portion of each of the one or more first containers associated with each of the one or more client signals further includes a second field, which is used to identify the overhead information of the corresponding client signal.

[0071] For example, the second field can be identification information of the corresponding client signal in the one or more client signals, and all the overhead portions included in the plurality of first containers carrying the same second field jointly carry the overhead information of the client signal identified by the second field.

[0072] Table 1 is a schematic table of the relationship between the first field and the second field in the embodiments of the present disclosure. Table 1 takes the transmission of four client signals in a first channel as an example. The second field can occupy 2 bits of the overhead portion of the S code block of the first container, which is used to indicate the overhead information of each of the client signals, such as the "service number" in Table 1. For example, the service number "00" can indicate that the corresponding first container carries the overhead information of the first client signal, the service number "01" can indicate that the corresponding first container carries the overhead information of the second client signal, the service number "10" can indicate that the corresponding first container carries the overhead information of the third client signal, and the service number "11" can indicate that the corresponding first container carries the overhead information of the fourth client signal. In addition, for each of the client signals, the overhead portion of the S code block can further include a first field, which can be used to indicate the part of the overhead information carried by the corresponding first container in the overhead information of each of the client signals. According to the first fields carried by the plurality of first containers associated with the client signal, an overhead group for carrying all the overhead information of the client signal can be formed, such as the "overhead group number" in Table 1. For example, the overhead information of each of the client signals is jointly carried by three first containers, i.e., the overhead portions of the three first containers with the overhead group numbers "01", "10" and "11" jointly carry the overhead information of one client signal.

[0073] Table 1

[0074] It can be understood that, by cooperation of the first field and the second field, the overhead information of one client signal can be jointly carried by multiple first containers, and the overhead information of multiple fixed bandwidth services can be respectively carried in the overhead sections of different first containers, and the multiple containers carrying the overhead information of the client signals can be identified by the second field carried in the overhead section of the first container, so that the bandwidth utilization is ensured.

[0075] In some embodiments, the payload section of each first container carries the one or multiple client signals. Referring to Table 1, four client signals can be carried by 12 first containers. Among them, the overhead sections of three first containers with service number "00" and overhead group numbers "01", "10" and "11" respectively jointly carry the overhead information of the first client signal; the overhead sections of three first containers with service number "01" and overhead group numbers "01", "10" and "11" respectively jointly carry the overhead information of the second client signal; and so on, each three first containers carry the overhead information of one client signal; meanwhile, the payload section of each first container in the 12 first containers carries the four client signals.

[0076] In some embodiments, the length occupied by the second field can be determined according to the number of client signals transmitted in the first channel.

[0077] In some embodiments, the overhead information at least includes at least one of the following: first information for indicating clock related information of the client signal; check information; client indication information of the client signal; and second information for indicating the payload padding information of the client signal in the first container. For example, the first information is clock related information of the client, the check information is cyclic redundancy check (CRC) check information, and the second information can be used to indicate the padding information of the payload section of the client signal in the first container, such as GMP padding information, for indicating the arrangement of stuff padding bytes in the payload section of the first container.

[0078] FIG. 4 is a schematic diagram of the overhead portion of a first container according to an embodiment of the present disclosure. FIG. 4 shows that each of the first containers carrying part of the overhead information corresponding to an overhead group. Each of the first containers carries a first field. For example, the first field in the first container shown in the first row is "01", the first field in the second container shown in the second row is "10", and the first field in the third container shown in the third row is "11". Thus, an overhead group is formed, indicating that the three first containers jointly carry an overhead group. In addition, "ij" in FIG. 4 is a second field, which is used to indicate that the overhead information carried by the first containers belongs to which client signal. "R" represents a reserved field.

[0079] In FIG. 4, some of the overhead information can be carried by the overhead portion of only one first container, such as the CRC check information carried in the first container with the first field being "01". Some of the overhead information needs to occupy the overhead portions of multiple first containers, such as the GMP padding information carried in the three first containers.

[0080] Based on the foregoing embodiment, the present disclosure further provides a transmission method. In the embodiment of the present disclosure, the method further includes: determining the carrying area of each of the one or more client signals in the payload portion of the first container while keeping the first length unchanged.

[0081] In the embodiment of the present disclosure, each of the first containers carries the one or more client signals. When filling the one or more client signals into the payload portion of each of the first containers, the first length of the first container is kept unchanged. The consistency of the first container can be maintained in various bandwidths of the first channel, various fixed service bandwidths, and various numbers of client signals, and the bandwidth utilization is improved.

[0082] In some embodiments, the first length can be kept unchanged by changing the byte division manner of the payload portion of the first container.

[0083] In some embodiments, the determination of the carrying area of each of the one or more client signals in the payload portion of the first container can include: in the case of transmitting one client signal in the first channel, determining that the payload portion of the first container is used to carry the client signal; and / or in the case of transmitting multiple client signals in the first channel, performing byte division on the payload portion of the first container to obtain a carrying area corresponding to each of the client signals. Different carrying areas are used to carry different client signals.

[0084] In some embodiments, in the case that only one customer signal is transmitted in the first channel, the one customer signal can be filled into the load part of the first container according to a Sigma / Delta algorithm; in the case that multiple customer signals are transmitted in the first channel, the first container can be divided into different carrying areas according to the customer signals, and the different carrying areas obtained by the division are used to carry different customer signals, and for the carrying area corresponding to each customer signal, the customer signal can be filled into the corresponding carrying area according to a Sigma / Delta algorithm.

[0085] In some embodiments, the byte division of the load part of the first container to obtain the carrying area corresponding to each customer signal can include: according to the number of the one or more customer signals, byte-dividing the load part of the first container to obtain the carrying area corresponding to each customer signal. For example, the first channel carries four customer signals, and the load part of the first container is divided into four carrying areas, and different carrying areas are used to carry different customer signals, and the bytes in the same carrying area can be continuous or discontinuous.

[0086] In some embodiments, the byte division of the load part of the first container can include: byte-dividing the load part of the first container according to a first mode or a second mode; wherein each carrying area obtained by the division according to the first mode includes interleaved bytes, and each carrying area obtained by the division according to the second mode includes continuous bytes.

[0087] As an example, the byte division of the load part of the first container according to the first mode can include: byte-dividing the load part of the first container according to a preset byte length to obtain a plurality of byte areas, and the length of each byte area is the preset byte length; according to the arrangement order of each customer signal in the one or more customer signals, sequentially assigning each byte area obtained by the division to the corresponding customer signal in a cyclic order, and all byte areas assigned to the same customer signal collectively form the carrying area corresponding to the customer signal. For example, the preset byte length is one byte or multiple bytes.

[0088] As another example, the byte division of the load part of the first container according to the second mode can include: determining the first number of the one or more customer signals, dividing the load part of the first container into a first number of continuous carrying areas, and assigning each carrying area to the corresponding customer signal.

[0089] In some embodiments, the first mode is, for example, a byte interleaving cyclic mode, and the second mode is, for example, a continuous byte division mode. FIG. 5 is an example diagram of a load part of a first container divided according to the first mode and the second mode respectively, which only takes the transmission of 4-way customer signals in a first channel as an example. In FIG. 5, D1 represents a bearing area corresponding to a first-way customer signal, D2 represents a bearing area corresponding to a second-way customer signal, D3 represents a bearing area corresponding to a third-way customer signal, and D4 represents a bearing area corresponding to a fourth-way customer signal. As shown in FIG. 5, after being divided according to the first mode, the four-way customer signals in the load part of the first container are cyclically interleaved, and the bearing areas corresponding to the customer signals are arranged in the load part of the first container according to the interleaving order, for example, cyclically interleaved and distributed in the order of D1, D2, D3, D4, D1, D2, D3, D4, D1, D2, and so on. After being divided according to the second mode, the four-way customer signals in the load part of the first container are sequentially distributed, for example, the first container is divided into four continuous areas, and each area is filled with each-way customer signal. It should be noted that the number information shown in FIG. 5 cannot represent the actual number information of the load part of the first container.

In the embodiments of the present disclosure, when a certain customer signal is not transmitted in the first channel or a certain customer signal has no actual signal, the first length of the first container remains unchanged, and the overhead information of the customer signal indicates that the corresponding bearing area is empty.

[0091] For example, the first bearing area is used to fill a first value. It can be understood that the first value is a preset fixed value in the first bearing area indicating empty. For example, in the case that the first customer signal has no actual transmitted signal in FIG. 5, the overhead information of the first customer signal can indicate empty, and the D1 area corresponding to the first customer signal is filled with the first value.

[0092] In some embodiments, in the case that the bandwidth of the first channel changes, the first length remains unchanged. In the embodiments of the present disclosure, the first length of the first container does not change with the bandwidth of the first channel, for example, the bandwidth of the fine-grained channel itself changes, and the first length of the first container carrying the fixed bandwidth service signal remains unchanged, thereby ensuring the consistency of the first container in the first channel and improving the bandwidth utilization.
