Construction and service method of time stamp service data in communication

technical field

The invention relates to a construction and service method of time stamp service data in communication, belonging to the technical field of communication. In particular, it relates to a communication service server that packs and performs priority calculations on the communication service content requested by the user according to the user's request, thereby constructing time stamp service data, and completing queuing and sending of the time stamp service data constructed above. Methods for billing and other services.

Background technique

With the continuous advancement of technology, the types of services and business content supported on terminals such as mobile phones, smart phones, the Internet, and computers are becoming more and more abundant. The mutual integration of telecommunication services and Internet services will become the development trend of next-generation network services. On the other hand, new changes have also taken place in users' demands on services. More data services no longer require instant transmission like voice services in the past, nor do they have the guarantee of transmission time like SMS or MMS. It needs to be transmitted according to the satisfaction of business users' individual needs, which is the timeliness demand.

In response to the need for timeliness, the current telecommunications system and the Internet use methods such as priority to distinguish services, but the granularity of the distinction is often coarse. For the same type of business, it is generally first-come-first-served, and the priority cannot be further differentiated. The business traffic in the network shows a more obvious burst feature, which brings greater pressure to upgrade the software and hardware of servers and processors in the network. For users, no matter whether the business they request is urgent or not, the services they get and the fees they pay cannot be distinguished, and users have no choice. Fees, etc. are not well linked. In addition, the existing methods of service data communication in the network cannot well solve the problem of timely transmission. Because various services have different requirements on delay and communication quality, there is a lack of unified guidelines and goals when queuing services and scheduling network resources. In addition, the complexity of various algorithms in the system is limited, and network performance is difficult to achieve. If it works well, user services cannot be guaranteed to be delivered on demand and in a timely manner.

One of the ways to realize on-demand service and timely transmission is to add a time tag to each business data, for example, the tag value is 5 minutes, 30 minutes and 2 hours to represent the urgency of the business. This kind of time-stamped business is called time-stamped business. The use of time tags allows network nodes to allocate network resources more reasonably according to time tag services, ensuring that the most needed and urgent services of users are served in a timely manner, and users who are not urgent can choose to allocate appropriate resources in their free time, and can pay accordingly The lower cost also alleviates the suddenness of network services and the tightness of resource allocation.
