Method of network management by assistance from terminal using control-plane signaling between terminal and network

摘要

Systems and methodologies are described that facilitate network management and optimization. As described herein, a network and a device communicating with the network can exchange network management information, thereby supporting a Self Organized Network (SON) architecture for improved network management and optimization performance. A Non-Access Stratum (NAS) layer protocol and/or an Internet Protocol (IP) application, in combination with a set of associated network management messages, can be utilized to exchange network management information between a device and a network. As further described herein, various procedures can be utilized to install a SON policy to a device in order to define device behavior for operations such as collecting and reporting information related to network management. Additionally, a set of standardized events can be defined, based on which a device can detect the occurrence of an event and report the occurrence to an associated network.

1. A method for logging and reporting network events, comprising:
receiving a Self Organized Network (SON) policy from a network that specifies a list of definitions for respective network events, a list of measurements to be performed that are associated with the respective network events, and instructions for reporting performed measurements associated with the respective network events; detecting an occurrence of a network event defined by the SON policy, wherein detecting an occurrence of a network event comprises detecting an occurrence of a radio link failure (RLF); performing one or more measurements associated with the detected network event based on the SON policy; storing information associated with the RLF in a register; and reporting the one or more measurements to the network based on the instructions for reporting measurements specified in the SON policy, wherein the reporting comprises
identifying a time of occurrence of at least one predefined triggering event, the at least one triggering event comprising at least one of quality of a communication link with the network having at least a predetermined threshold quality or the register becoming full; andtransferring at least a portion of information stored in the register to the network based on at least one of quality of a communication link or the register being full, and wherein the portion of information includes a timestamp indicating the identified time of occurrence.
