ABSTRACT:
The application discloses a method and apparatus for providing interoperability for a mobile subscriber unit (MSU), employing a first protocol e.g., SCEP, with a packet-data subsystem operating at a second protocol e.g., SNDCP. The method includes determining that the first protocol employed by the MSU is different from the second protocol operated by the packet data subsystem. The method then includes creating a context information for the MSU when the determined first protocol is different from the second protocol. Further, the method includes determining a header associated with the second protocol based on the created context information and then receiving at least one data packet associated with the first protocol from the MSU. The method then encapsulates the at least one data packet with the determined header associated with the second protocol. The method then transmits the at least one encapsulated data packet to the communication network through a context manager.
