Problems solved by technology

[0005] For the existing association technology described above, it has the following defects: the indirect association must be performed through the cut-out process of the S1-MME interface, which consumes performance; in addition, when UE (User Equipment, user equipment) enters the monitoring point from outside the monitoring point When it is inside, due to the monitoring range, the original cut-out process is not detected, which will cause associated failure
[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Embodiment Construction

[0024] 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.

[0025] In the LTE system, when a scene switch occurs, the network device will allocate certain resources for the user between the target eNodeB and the target SGW (Serving GateWay, Serving Gateway) (SGW may also remain unchanged), and this resource It is embodied as a "user plane tunnel". Two tunnels are allocated during the communication process, one is an uplink tunnel, through which UE (User Equipment, user equipment) data is sent to the external network; the other is a downlink tunnel, through which external network data is sent to the UE . During the communication process, these two tunnels ...

Abstract

The invention provides a correlation method of signaling processes of an S1-MME interface and an S11 interface in internal switching scenes of an LTE system. The method includes following steps: tunnel information of a first user interface is extracted from the S1-MME interface, and the information comprises tunnel information of a first uplink user interface and a first downlink user interface; tunnel information of a second user interface is extracted from the S11 interface, and the information comprises tunnel information of a second uplink user interface and a second downlink user interface; the tunnel information of the first uplink user interface and the tunnel information of the second uplink user interface are compared, or the tunnel information of the first downlink user interface and the tunnel information of the second downlink user interface are compared; whether comparison results are the same is determined; and if the comparison results are the same, signaling processes of the S1-MME interface and the S11 interface are correlated. According to the correlation method, the correlation of signaling processes of the S1-MME interface and the S11 interface can be conveniently realized, the processing is simple and feasible, the accuracy is high, and the practicality is high.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for associating signaling processes of an S1-MME interface and an S11 interface in an LTE system internal handover scenario. Background technique [0002] The S1 interface is a communication interface between an eNodeB (evolved NodeB, evolved eNodeB) and an EPC (Evolved Packet Core, evolved packet core network) in an LTE (Long Term Evolution, long-term evolution) system. The S1 interface is further divided into two interfaces, the S1-MME interface used for the control plane and the S1-U interface used for the user plane. The S1-MME interface connects the eNodeB with the MME (Mobility Management Entity, Mobility Management Entity), and mainly completes functions such as wireless access bearer control of the S1 interface and dedicated operation and maintenance of the interface. The user plane interface S1-U connects the base station with an SGW (Servi...
