Problems solved by technology

[0006] However, in the LTE (Long Term Evolved, long-term evolution) network, the eNB (evolved Node B, evolved base station) does not know the IMSI, and due to the evolution of the network architecture, there is no network element such as the RNC in LTE to obtain the IMSI, so , in the LTE network, the eNB does not know the IMSI
The existing method of signaling association cannot be realized

specific Embodiment 1

[0064] see Figure 5 , the signaling association of the source base station includes the following process:

[0065] Step1: When receiving the message msg1: X2Handover Request copied by the source base station, record the SCTPIndex and Old eNB UE X2AP ID of the message;

[0066] Step2: Whether the message msg2: X2Handover Req Ack received from the source base station is received within the effective time receiving window, if not, the process ends;

[0067] Step3: Determine whether the Old eNB UE X2AP ID carried by msg2 is the same as the recorded one, if not, return to step2;

[0068] Step4: Associate multiple msg1 and msg2 according to the Old eNB UE X2AP ID;

[0069] Step5: Determine whether there are multiple associated pairs of msg1 and msg2 (multi-preparation set scenario), if not, the process ends;

[0070] Step6: Whether the message msg5: X2UE Context Release received from the source base station within the valid time window, if not, the process ends;

[0071] Step7...

specific Embodiment 2

[0072] see Figure 6 , the signaling association of the target base station includes the following process:

[0073] Step1: Receive the message msg3: S1Path Switch Request copied by the target base station, and record the eNB UE S1AP ID of the message;

[0074] Step2: Whether the message msg4: S1Path Switch Request Acknowledge received from the target base station is received within the valid time window, if not, the process ends;

[0075] Step3: Determine whether the eNB UE S1AP carried in the message is the same as the recorded one, if not, the process ends.

[0076] If they are the same, msg3 and msg4 are associated successfully, and the process ends.

specific Embodiment 3

[0077] see Figure 7 , the concatenation of various signaling includes the following process:

[0078] Step1: Obtain the relationship between eNB UE S1AP (target base station) and MME UE S1AP ID (source base station) according to msg3;

[0079] Step2: Obtain the relationship between eNB UE S1AP (target base station) and MME UE S1AP ID (target base station) according to msg4;

[0080] Step3: Associate the relationship between MME UE S1AP ID (source base station) and MME UE S1AP ID (target base station);

[0081] Step4: According to the initial context establishment and path switching messages, obtain the association relationship between the source base station and the target base station's respective eNB UE S1AP and MME UE S1AP ID;

[0082] Step5: Associate the source base station eNB UE S1AP with the target base station eNB UE S1AP ID.

[0083] see Figure 8 , a signaling association device provided by an embodiment of the present invention includes:

Abstract

The embodiment of the invention provides a signaling relevance method and a signaling relevance device, which are used for carrying out relevance on different signaling of UE (user equipment) when eNB (effective noise bandwidth) switching is generated under the condition that IMSI (international mobile subscriber identity) is unknown. The method comprises the following steps that S1 interface messages which are copied by the first eNB and correspond to the same UE are subjected to relevance, wherein the S1 interface messages are S1 interface messages generated when the second eNB is switched to the first eNB; and according to the related S1 interface messages corresponding to the same UE, the UE is related at the S1 interface application protocol identification in the first eNB and the S1 interface application protocol identification in the second eNB.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a signaling association method and device. Background technique [0002] In the engineering network optimization and operation and maintenance optimization phases of mobile communication networks, in order to locate problems in the network, it is necessary to track the signaling of user terminals to obtain signaling conditions before and after abnormal faults (such as dropped calls, dropped calls, etc.), which is convenient In-depth analysis of the problem. In 3G (3 rd -Generation, third-generation mobile communication technology) era, since the RNC (Radio Network Controller, radio network controller) of the access network can obtain the user's IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity), it can be unique through IMSI to identify the user. In this way, on the operation interface of the tracking tool, the maintenance pers...
