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 Figure 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 a higher service transmission rate; the connection on the control plane remains on the Macro eNB to prevent the UE from dropping the call 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.

Abstract

The invention discloses a method and user equipment for differentiating signal sources. The method includes that the UE (user equipment) is simultaneously connected with control panels of two base stations eNB and receives signals from the control panels of the optional base stations eNB; the UE determines relevant identification information used for instructing the base stations eNB according to the signals of the control panels, and determines the base stations which are the sources of the signals of the control panels according to the relevant identification information. The method and the user equipment have the advantage that the problem of increase of risks of communication interrupt when existing UE is switched due to great increase of UE switching frequency and times in a layered network structure in an existing E-UTRAN (evolved universal terrestrial radio access network) architecture can be solved.

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...
