Mobility management method and apparatus in high speed railway

摘要

The invention discloses a method of mobility management in high speed railway, comprising: identifying whether a User Equipment (UE) is a high speed railway UE; if the UE is identified as a high speed railway UE, obtaining a high speed railway neighbor cell list for the UE, wherein the high speed railway neighbor cell list only includes high speed railway cell; and triggering a fast and earlier cell reselection, or cell handover, or both. This improves the mobility handling for high speed railway UE, decreased dropping risk and better user experienced performance are also provided.

1. A method of mobility management in a high speed railway, comprising:
identifying whether a User Equipment (UE) is a high speed railway UE that camps on or connects to a high speed railway cell serving the high speed railway; if the UE is identified as a high speed railway UE, obtaining a high speed railway neighbor cell list for the UE, wherein the high speed railway neighbor cell list only includes one or more high speed railway cells serving the high speed railway, and wherein each of the one or more high speed railway cells in the high speed railway neighbor cell list is represented by an identifier identifying the cell; and triggering at least one of cell reselection and cell handover based on the high speed railway neighbor cell list.
