Method for cell traffic trace messages and mobility management entity

Abstract

The embodiment of the present invention provides a method for cell traffic trace messages and a mobility management entity. The method for cell traffic trace messages includes: acquiring a cell traffic trace message sent by a current base station, wherein the cell traffic trace message includes the base station information of the current base station; if the current base station is in an allowed base station set, determining whether the number of cell traffic trace messages received within a predetermined time exceeds a cell traffic trace message limit; if so, discarding cell traffic trace messages sent by the current base station; and if not, processing the cell traffic trace messages sent by the current base station. When a wireless-side base station initiates cell traffic trace, the method for cell traffic trace messages controls the number of processed cell traffic trace messages at a core network MME network element to protect the MME network element against the impact of massivetracking messages.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cell tracking message method and a mobility management entity. Background technique [0002] Cell Traffic Trace (Cell Traffic Trace) is the 4G (The 4th Generation Mobile Communication Technology, fourth generation mobile communication technology) wireless side to the user according to the cell (Cell, the area covered by the wireless signal in mobile communication is called a cell, in LTE, An eNodeB may include signaling tracking performed by multiple cells), and is used to report wireless signaling of users in the tracked cells. However, the wireless side does not have the user's IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number), IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity Code) information, so it needs to be notified through Cell Traffic Trace (message name for ce...

Problems solved by technology

[0005] First of all, in the network deployment of operators, it is a high probability event that MME and eNodeB use multi-vendor products, but it is difficult to require both eNodeB and MME products to use the same non-standard message. In this way, as long as MME or eNodeB does not implement non-standard message , the cell tracking cannot be restricted, and the MME network element and its OMM are bound to be impacted by massive cell tracking messages

[0006] Secondly, even if all eNodeB and MME manufacturers have implemented non-standard messages according to the requirements of operators, due to the huge number of eNodeBs, it is necessary to upgrade or patch the eNodeBs already on the network, resulting in a large maintenance workload and high maintenance risks
