Abstract:
1. A method for transmitting signaling trace command, comprising the steps of: carrying a plurality of signaling trace configuration parameters, which respectively correspond to a plurality of signaling traces, in the signaling trace command, wherein the plurality of signaling traces correspond to a User Equipment (UE); and transmitting the signaling trace command to activate or maintain the plurality of signaling traces; wherein the signaling trace configuration parameters corresponding to the plurality of signaling traces are carried by setting a cell format in the signaling trace command to be a form of array; wherein X2 interface handover occurs on a User Equipment (UE) corresponding to the plurality of signaling traces; wherein the signaling trace command is a handover request message on the X2 interface; and wherein the step of transmitting the signaling trace command further comprising: transmitting, by a switched source evolved NodeB (eNB), the handover request message to a switched target eNB to maintain the plurality of signaling traces of the UE; or S1 interface handover occurs on a UE corresponding to a plurality of signaling traces; wherein the signaling trace command is a handover request message on the S1 interface; wherein transmitting the signaling trace command further comprising: transmitting, by a Mobility Management Entity (MME), the handover request message to a switched target eNB to maintain the plurality of signaling traces of the UE; or a UE corresponding to a plurality of signaling traces has not established an S1 link; wherein the signaling trace command includes a signaling trace start message or a context setup request message; wherein transmitting the signaling trace command further comprising: when the UE successfully establishes an S1 link, transmitting, by a MME, the signaling trace command to an eNB corresponding to the UE to activate the plurality of signaling traces of the UE; or the plurality of signaling traces is activated in a cell; wherein the signaling trace command is a cell trace message; wherein transmitting the signaling trace command further comprising: transmitting, by an eNB corresponding to the cell, the cell trace message to an MME for the MME to activate the plurality of signaling traces of UEs in the cell.
