Problems solved by technology

In the LTE (Long Term Evolved, long-term evolution) network, the eNB does not know the IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number), and due to the evolution of the network architecture, there is no RNC (Radio Network Controller, wireless A network element such as a network controller) obtains the IMSI; therefore, in the LTE network, it is impossible to realize the multi-interface handover message association of a single user according to the original signaling association method

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] The main implementation scheme of the present invention is as follows: before and after the user switching of the LTE network, the switching record CDR (i.e. Calling detail records, call detailed records) of the S1-MME (S1for the control plane, control plane S1 interface) interface is collected, and the CDR includes : The CDR switched in by the S1-MME interface, the CDR switched out by the S1-MME interface, and the key value is set in the switching record CDR of each corresponding S1-MME interface; according to the key value, multiple data interfaces that meet the preset conditions The CDR i...

Abstract

The invention is applicable to the technical field of signal monitoring of a mobile internet and provides a method and system for associating signaling messages in the LTE network switching process. The method specifically comprises the following steps: firstly, call detail records (CDR) of S1-MME interfaces of a source eNB and a target eNB are respectively acquired, wherein the CDR include key values; secondly, the acquired key values of the S1-MME interfaces of the source eNB and the target eNB are respectively analyzed; finally, the key values are compared and analyzed, and the two CDR are associated if the key values are consistent. The method and system for associating the signaling messages in the LTE network switching process meet the existing demand for S1-MME interface based association analysis of LTE network service, enable the complete switching process of a user to be clear and definite, enable previous and later switching messages of the user to be associated and provide reliable technical support for scene switching optimization.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method and system for associating signaling messages in an LTE network handover process. Background technique [0002] As a transition between the third-generation mobile communication 3G and the fourth-generation mobile communication 4G, the Long Term Evolution (Long Term Evolution, Long Term Evolution) network communication technology can provide higher data transmission rates and support various data transmissions. And provide seamless connection to mobile devices. [0003] The LTE network adopts a flat network structure. The LTE system mainly includes two parts: E-UTRAN (Evolved Universal Mobile Communications Radio Access Network) and EPC (Evolved Packet Switching Core Network). ), each eNB includes multiple cells, and the eNBs are interconnected through the X2 interface; EPC is composed of S-GW (Serving Gateway) and MME (Mobility Management Entit...
