Abstract
A method, a device, and a system for controlling tunnel identifier allocation are provided. The method includes: determining whether a type of a current procedure allows a Serving Gateway (SGW) to change a Tunnel Endpoint Identifier (TEID) and/or an Internet Protocol (IP) address (S110); and sending an modify bearer request message to the SGW, in which the modify bearer request message is used for notifying the SGW of whether the SGW is allowed to change the TEID and/or the IP address (S120). The loss of service data packets of a user or the service interruption caused by that the SGW modifies the TEID and/or the IP address is avoided.
