Claim Text:
1. A signaling tracing method, comprising: receiving, by a base station, first signaling tracing configuration information sent by an operation administration maintenance (OAM) device for initiating a signaling tracing for a user equipment, wherein the first signaling tracing configuration information carries a user equipment identifier corresponding to the user equipment; sending, by the base station, the first signaling tracing configuration information to a first core network node; receiving, by a serving base station, second signaling tracing configuration information sent by a serving core network node, wherein the second signaling tracing configuration information is obtained by the serving core network node based on the first signaling tracing configuration information, which is provided to the serving core network node by the first core network node after determining that a context of the user equipment does not exist in the first core network node; and initiating, by the serving base station, the signaling tracing for the user equipment based on the second signaling tracing configuration information; wherein the first core network node is different from the serving core network node and the first core network node and the serving core network node are both mobility management entities (MMEs).
