Benefits of technology

The technical effect of this patented technology allows for efficient rearrangement when an encrypted communication session fails due to differences or changes made during transmission over different networks (NW). This ensures continuous services are provided even if there were any issues with one network's protocol being used more frequently than another) while still providing reliable data transfers through these types of connections.

Problems solved by technology

Technological Problem addressed in this patents relating to wireless networks where multiple base stations provide services within their coverage areas while maintaining security measures against attacks caused by external sources like users' devices. Current solutions require manual intervention and have limitations in effectiveness because they only work at specific times based upon predetermined criteria.

Abstract

The invention discloses a repositioning processing method which comprises the following steps: the type of repositioning is as follows: when the repositioning does not involve a service radio network subsystem of user equipment, a target radio network controller (RNC) checks out that an encryption algorithm currently used by a source RNC in a repositioning request message is not matched with the encryption algorithm selected by a target RNC; and the target RNC returns a repositioning failure message to the source RNC. The invention also discloses a repositioning processing system. In the system, when the encryption algorithm currently used by the source RNC is not matched with the encryption algorithm selected by the target RNC, the target RNC returns the repositioning failure message to the source RNC through a repositioning failure message feedback unit. By adopting the method and the system, the problem of repositioning process failure caused as the encryption algorithm selected by the target RNC is different from the encryption algorithm currently used by the source RNC in the scene of SRNS repositioning not involving the UE can be solved.
