METHODS, APPARATUSES AND SYSTEMS FOR ACCESSING MULTI-OPERATOR CORE NETWORK

摘要

The embodiments of the present invention provide methods, apparatuses and systems for accessing a multi-operator core network. One of the methods includes: a second Serving GPRS Supporting Node (SGSN) obtains Logical Link Control (LLC) parameters of a first SGSN from an access network device, wherein the LLC parameters of the first SGSN is sent from the first SGSN to the access network device (101); and the second SGSN interacts with a Mobile Station (MS) using the LLC parameters of the first SGSN (102).
