发明名称 METHOD OF SUPPLYING PACKET DATA SERVICE IN V5.2 WLL SYSTEM
摘要 <p>PURPOSE: A method of supplying a packet data service in a V5.2 WLL system is provided to add information to a message for a V5.2 interface, or to transmit a designated receiving information factor, thereby supplying packet data service state management information as supporting a packet data service for a subscriber requesting a packet data service call. CONSTITUTION: An AN(Access Network) generates an establish message, and transmits the message to an LE(Local Exchange)(S1). The LE receives the message(S2), initializes a PSTN path, and transmits a result to the AN(S3). The LE transmits an allocation message to the AN by generating the allocation message(S4). The AN receives the allocation message(S5), allocates a bearer channel(S6), and loads a result to the allocation message, then transmits the message to the LE. The AN confirms whether a subscriber requesting a call wants a packet data service(S7). The AN adds information, which informs the subscriber that the requested service is the packet data service, to a service option information factor(S8). The AN loads the information into an allocation completion message with a bearer channel allocation result, and transmits the message to the LE(S9).</p>
