Method and system for signaling reduction on radio access networks using targeted intelligence for communication devices

摘要

An intelligent system and an algorithm at a packet network to reduce the amount of signaling in the radio access network and core network is defined. The system collects all the necessary information from the signaling exchange between the radio access network and the core network and takes the subscription characteristics and policy information into consideration to choose the optimal way of reducing the amount of signaling including selecting the optimal bearers for certain types of communications and paging selected area instead of the whole area for each device. The bearer selection algorithm takes several things as input to choose the optimal bearer to perform the task.

1. A machine-implemented method performed within a network element of a packet core for selecting a bearer to transfer data with a user device responsive to a command from a network application to the user device, the method comprising:
receiving the command from the network application; analyzing the command for various criteria, including at least one of frequency, size of data, quality of service, time criticality, mission criticality, and duration; making a preliminary selection of the bearer to require minimum overall signaling exchanges with minimum overall packet counts for the data transfer to deliver the command to the user device based on the analysis; collecting a current mobility and session state of the user device at a time of establishing the bearer; modifying the preliminary bearer selection based on the current mobility and session state of the user device such that the minimum overall signaling exchanges for the data transfer is minimized at the time of establishing the bearer to form a final bearer selection; and establishing the bearer based on the final bearer selection to send the command to the user device.
