Description

A relocation processing method, device and wireless network controller

technical field

The invention relates to the field of mobile communication, in particular to a relocation processing method, device and wireless network controller.

Background technique

The Universal Mobile Telecommunication System (UMTS for short) belongs to the third generation communication system. The network part of UMTS is called UMTS Terrestrial Radio Access Network (UTRAN for short), and UTRAN is divided into radio access network Access network (Radio Access Network, referred to as RAN) and core network (CoreNetwork, referred to as CN), where RAN is used to handle all wireless-related functions, while CN is used to handle all voice calls and data connections in the system and external networks switching and routing. Moreover, the RAN, the CN and the user equipment (User Equipment, UE for short) together constitute the whole system. The network units of the radio access network include a radio network controller (Radio Network Controller, RNC for short) and a transceiver base station (Node B, NodeB for short).

In practical applications, during the mobile process of the UE, the first RNC establishes an IUR interface connection with the second RNC, and the first RNC initiates a wireless link establishment request or a wireless link addition request to the second RNC, and the second RNC communicates through the IUR interface. The radio link establishment response or the radio link addition response in the RNSAP protocol feeds back E-UTRA neighboring cell information (Neighboring E-UTRA Cell Information) to the first RNC, wherein the neighboring cell information carries the cell identity.

When the UE moves to the boundary between UTRAN and E-UTRAN, and needs to be handed over to the E-UTRAN cell for the continuity of the service of the UE, the first RNC needs to initiate a relocation request to the CN, and fill in the IU port wireless access network application protocol When relocating the target ID (Target ID) of the request in RANAP, it is necessary to fill in whether the base station ID (eNB ID) is a macro base station ID (Macro eNB ID) or a home base station ID (Home eNBID).

However, the second RNC did not inform the first RNC whether it carried a Macro eNB ID or a Home eNBID. As a result, when the first RNC initiated a relocation request to the CN, it could not accurately inform the CN whether it was a Macro eNB ID or a Home eNB ID. If the relocation request The base station ID filled in does not match the real base station ID of the E-UTRAN cell, which may easily lead to relocation failure and make it difficult to ensure the continuity of UE services.
