Problems solved by technology

[0011] The present invention provides a method for distinguishing signaling sources and user equipment to solve the problem that in the hierarchical network structure of the existing E-UTRAN network architecture, the switching frequency and times of the UE are greatly increased, thereby increasing the number of UEs in the network. The problem with the risk of communication loss when switching

Embodiment Construction

[0032] In order to reduce the frequency of UE switching between the Macro eNB cell and the Local eNB cell, a network deployment method in which the user plane and the control plane are separated is introduced. as attached Image 6 As shown, in this way, when the UE is in the area covered by the Macro eNB cell, both the control plane and the user plane of the UE are connected to the Macro eNB; when the UE moves to the overlapping coverage area of ​​the Macro eNB cell and the Local eNB cell, the UE user All or part of the bearers on the plane are transferred to the Local eNB to obtain higher service transmission rates; the connection on the control plane remains on the Macro eNB to prevent the UE from dropping calls due to the failure of the control plane connection handover.

[0033] Among them, the Macro eNB is an LTE macro base station; the Local eNB is an LTE micro base station (Pico eNB) or a home base station (Home eNB) or a relay (Relay) device, etc.

[0034] In the case...

Abstract

Disclosed are a method and a user equipment for distinguishing signaling sources, so as to solve the problem of growing risks of communication interruptions that occur during a handover of a UE because the handover frequency and times of a UE grow significantly in a layered network structure in an existing E-UTRAN network architecture. The method comprises: a UE keeping a control plane connection with two eNBs at the same time, and receiving control plane signaling from a random eNB; the UE determining identifier relevant information for indicating the eNB according to the control plane signaling, and determining the eNB being the source of the control plane signaling according to the identifier relevant information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for distinguishing signaling sources and user equipment. Background technique [0002] as attached figure 1 As shown in the schematic diagram of the network architecture of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), the E-UTRAN is composed of an evolved base station (eNB). [0003] The Mobility Management Entity (MME) is connected to the eNB through the S1-MME interface; the eNB completes the access network function and communicates with the user equipment (UE) through the air interface. For each UE attached to the network, there is an MME providing services for it, and the MME is called the serving MME of the UE. The S1-MME interface provides UE with control plane services, including mobility management and bearer management functions. [0004] The serving gateway (Serving GW, S...
