Method for realizing user accessibility and multi-mode terminal

摘要

The disclosure discloses a method for realizing user accessibility and a multi-mode terminal. A UE initiates, after a tracking area update (TAU) periodic timer of the UE expires, an update process to a mobile switching center/visitor location register (MSC/VLR) in the case that an idle mode signaling reduction (ISR) is activated and the UE resides in a global system for mobile communications/universal mobile telecommunication system (GSM/UMTS). The disclosure improves user experience.

主权项

1. A method for realizing user accessibility, comprising:
performing an activation of an idle mode signaling reduction (ISR) mode at a multi-mode user equipment (UE) in response to the UE being simultaneously registered with both a global system for mobile communications (GSM)/universal mobile telecommunication system (UMTS) network and a long term evolution (LTE) network; and after the UE moves to the coverage of the GSM/UMTS, while the ISR is active, in response to detecting an expiration of a LTE tracking area update (TAU) periodic timer of the UE, initiating a combined Routing Area/Location Area Update, or initiating an Location Area Update process by the UE to a mobile switching center (MSC)/visitor location register (VLR), the update process is varied depending on a network operating mode of the GSM/UMTS network, and is configured to event the MSC/VLR to identify the UE as being implicit detach.
