Abstract
A service processing method and a service processing device are disclosed. The service processing method may include: determining overhead information and determining a payload area for carrying the overhead information and service data in a bearer frame when a low-rate client service is borne in a communication network; and mapping the overhead information and the service data to the payload area.
Claims20
A service processing method, comprising:
- determining overhead information and determining a payload area for carrying the overhead information and service data in a bearer frame, in response to a low-rate client service being borne in a communication network;
- and
- mapping the overhead information and the service data to the payload area;
- wherein the low-rate client service has finer service granularity than a sub-slot;
- wherein the bearer frame is a specific code block stream comprising an S block, a D block, and a T block, the payload area comprises at least one of a byte in the D block, a byte other than a control byte in the S block, or a byte other than a control byte in the T block, and wherein the S block, the D blocks and the T block occupy 66 bits, respectively, the S block comprises a synchronization header of 2 bits and a frame header code block occupying at least one byte, the T block comprises a synchronization header of 2 bits and an end code block occupying at least one byte, the D block located between the S block and the T block comprises eight bytes for carrying service data;
- and
- wherein the service data is carried in the payload area according to one of the following mapping modes:
- mapping mode one:
- a transmission rate of the bearer frame is the same as a service rate, and the payload area of the bearer frame directly carries service data of a service corresponding to the bearer frame;
- mapping mode two:
- the transmission rate of each bearer frame is the same, and a size of the payload area of the bearer frame is adjusted to carry service data of a service corresponding to the bearer frame;
- or
- mapping mode three:
- the transmission rate of each bearer frames is the same, a plurality of client services are carried in the payload area of the bearer frame, the payload area of the bearer frame is divided into a plurality of service carrying areas, and a size of each of the service carrying areas is adjusted to carry service data of the service corresponding to a respective one of the service carrying areas.

A service processing device, comprising at least one processor and a memory communicatively connected to the at least one processor, wherein the memory stores an instruction executable by the at least one processor which, when executed by the at least one processor, causes the at least one processor to perform a service processing method, comprising:
- determining overhead information and determining a payload area for carrying the overhead information and service data in a bearer frame, in response to a low-rate client service being borne in a communication network;
- and
- mapping the overhead information and the service data to the payload area;

- and
- wherein the service data is carried in the payload area according to one of the following mapping modes:
- mapping mode one:
- a transmission rate of the bearer frame is the same as a service rate, and the payload area of the bearer frame directly carries service data of a service corresponding to the bearer frame;
- mapping mode two:
- the transmission rate of each bearer frame is the same, and a size of the payload area of the bearer frame is adjusted to carry service data of a service corresponding to the bearer frame;
- or
- mapping mode three:
- the transmission rate of each bearer frames is the same, a plurality of client services are carried in the payload area of the bearer frame, the payload area of the bearer frame is divided into a plurality of service carrying areas, and a size of each of the service carrying areas is adjusted to carry service data of the service corresponding to a respective one of the service carrying areas.
