A method, an apparatus, and a system for managing emergency services of a mobility-restricted Mobile Station (MS) are disclosed. The method includes: an Anchor-Service Flow Authorization entity (A-SFA) obtains emergency service information or an Emergency Service Flag (ES_Flag), where the emergency service information or the ES_Flag serves as an indication of providing emergency services for the mobility-restricted Mobile Station (MS); constructs, according to the emergency service information or the ES_Flag, an emergency service indicator in an MS context maintained by the A-SFA; and sends a Path Registration Request (Path_Reg_Req) to a Base Station (BS), where the Path_Reg_Req carries the ES_Flag if what is obtained is the ES_Flag; or, if what is obtained is the emergency service information, generates the ES_Flag according to the emergency service indicator or emergency service information, and adds the generated ES_Flag into the Path_Reg_Req. |
