Access control method and system during handover

Abstract

The present invention discloses a method for access control during handover. The method includes: the source network side sends handover signaling to the target network side; the handover signaling includes the throughput of user equipment in the source cell; the target network side receives the handover signal After the order, the access control is implemented according to the throughput of the user equipment in the source cell or the quality of service parameters of the radio access bearer. The present invention also discloses an access control system during handover. The system includes an access control unit, which is used when the target network side receives the handover signaling from the source network side, according to the user equipment in the source cell. The throughput, or the quality of service parameter of the radio access bearer implements access control; wherein, the throughput of the user equipment in the source cell is included in the handover signaling. By adopting the method and system of the present invention, the access control can be performed according to the actual service requirements of the UE, so that the experience of the user will not be affected.

Description

technical field [0001] The present invention relates to the control technology at the time of handover, in particular to an access control method and system at the time of handover. Background technique [0002] In a mobile communication system, in order to meet the mobility requirements, after the user equipment (UE, UserEquipment) establishes a connection with the network in the serving cell, that is, the source cell, the UE still needs to measure the signal quality of its serving cell and neighboring cells, so that Select a more suitable cell for handover. During the handover process, the target cell needs to implement access control for the UE. If resources permit, the UE's handover request is allowed. The specific handover process is as follows: figure 1 As shown, the Evolved Universal Terrestrial Radio Access Network (EUTRAN, Evolved Universal Terrestrial Radio Access Network) is taken as an example here, figure 1 The switching process includes the following steps: ...

AI Technical Summary

Problems solved by technology

[0014] One situation is: when the target base station finds that the UE is establishing a GBR service, it needs to implement access control according to GBR, and since the actual throughput of the UE in the source cell is not considered in this access control process, here The Throughput can also be understood as traffic. Therefore, if the actual throughput of the UE exceeds the GBR, the target base station can only implement access control according to the GBR and allocate resources for the UE. The resulting problem is: the service rate of the UE after handover It is greatly reduced, which affects the user experience; another situation is: if the target base station finds that the UE has established a non-GBR service, because the target base station does not consider the actual throughput of the UE in the source cell and implements access control, the resulting problem is : Too many or too few resources are allocated or reserved for the UE. When too many resources are allocated to the UE, resources will be wasted, and too few resources are allocated to the UE. The service rate of the UE will be greatly reduced after handover , will also affect the user experience

In short, when implementing access control in the prior art, since the actual throughput of the UE in the source cell is not considered, access control cannot be performed according to the actual service requirements of the UE, thereby affecting user experience
