Before being powered off, the synchronous terminal stores a CDMA channel number that it uses at the present time, a CDMA area list, a system identification (SID) list, a network identification (NID) list and other information in its memory.

FIG. 9B shows a format of a synchronous channel message received by a synchronous terminal when a core network connected to the radio network is ANSI-41 core network.
[0180]FIG. 11 shows a method for interfacing a hybrid type synchronous terminal with a core network in accordance with the present invention.
[0181]FIG. 11A is a flowchart illustrating a procedure where a hybrid type synchronous radio network including a base transceiver station (BTS) and a base station controller (BSC) determines the operating type of the core network and sends information about the core network, for example, core network operating type information and information related to core network, to the hybrid type synchronous terminal.
Thereafter, the. BSC determines at step S12 whether the connected core network is a synchronous ANSI-41 core network. If the connected core network is the synchronous ANSI-41 core network, the BSC sets core network operating type information CN Type corresponding to the detected core network operating type at step S15.
[0190]FIG. 9A is a view showing a format of the Sync channel message when the core network connected to the hybrid type synchronous radio network is the GSM-MAP network. As shown in this drawing, the core network operating type information CN Type of “0” or “1” is written in a first field of the Sync channel message and information elements related to the GSM-MAP network, PLMN identity information PLMN_ID, CN domain identity information and NAS system information, are sequentially written in the subsequent fields of the message. As described above, the same information elements as those in the conventional Sync channel message shown in FIG. 7A are sequentially written from the next field of the present Sync channel message.
[0191]FIG. 9B is a view showing a format of the Sync channel message when the core network connected to the hybrid type synchronous radio work is the ANSI-41 network. As shown in this drawing, the core network operating type information CN Type of “0” or “1” is written in a first field of the Sync channel message and information elements related to the ANSI-41 network, an 8 bits protocol revision level, an 8 bits minimum protocol revision level, a 15 bits system identification and a 16 bits network identification, are sequentially written in the subsequent fields of the message. The same information elements as those in the conventional Sync channel message shown in FIG. 7A are sequentially written from the next field of the present Sync channel message.
Thereafter, the BSC in the hybrid. type synchronous radio network sends the Sync channel message having the CN operating type information to the hybrid type synchronous terminal over a Sync channel at step S17.
That is, upon being. powered on, the synchronous terminal selects a CDMA system on the basis of a CDMA channel number, a CDMA area list, an SID list, an NID list and other information stored in its memory and a CDMA system selection algorithm provided from a terminal manufacturer at step S21.
Then, the hybrid type synchronous terminal acquires a pilot having the same. CDMA channel number as that of the selected CDMA system at step S22. In other words, after selecting the CDMA system, the hybrid type synchronous terminal acquires a pilot having the same CDMA channel number as that of the selected CDMA system, or CDMA frequency number as that. corresponding to the selected CDMA system.
After acquiring the pilot, the hybrid type. synchronous terminal proceeds to step S23 to perform a Sync channel acquisition operation and then to step S24 to receive a Sync channel message over the acquired Sync channel.
Accordingly, the hybrid type synchronous terminal determines at step 526 whether the CN Type information value is “1” and proceeds to step S27 if the CN Type information value is “1”. At step S27, the synchronous terminal analyzes information elements related to the core network as those for the ANSI-41 core network and stores desired ones of them in its memory. At this time, the stored information elements are system identification (SID), network identification (NID), a minimum protocol. revision level (MIN_P_REV) and a protocol revision level (P_REV).
Thereafter, at. step S28, the hybrid type synchronous terminal selects a synchronous CC part and a synchronous MM part for the ANSI-41 network and sets protocols according to the selected operating type. Subsequently, the hybrid type synchronous terminal synchronizes its timing with that of a base transceiver station in the selected system at step S29 and then performs a message interfacing operation with the ANSI-41 core network at step S30.
As described above, the method or the apparatus for interfacing in accordance with the present invention adaptively sets a protocol on the basis of an operating type of the core network and smoothly interfaces among the terminal, the base station and the core network. Preferred formats of messages. communicated between the terminal and the base station in order to perform setting and interfacing functions are illustrated in FIGS. 10A to and 10D.
[0207]FIGS. 10A and 10B show a format of a master information block in a system information message received by a hybrid type asynchronous terminal when a core network connected to a universal mobile telecommunication system (UMTS) terrestrial radio access. network (UTRAN) is an asynchronous GSM-MAP core network. FIGS. 10C and 10D show a format of a master information block in a system information message received by a hybrid type asynchronous terminal when a core network connected to the UTRAN is a synchronous ANSI-41 core network.
If the core network operating type information is ANSI-41 information representing a synchronous core network, the information related to core network includes a revision level (P_REV) representing a revision level of a system protocol, a minimum. revision level (M P_REV), a system identification (SID) and network identification (NID). If the core network operating type information is GSM-MAP information representing an asynchronous core network, the information related to core network includes public land mobile network identity (PLMN_ID).
[0209]FIG. 12A is a flowchart illustrating a procedure where a hybrid type radio network controller (RNC) in an asynchronous radio network, or UTRAN, determines the operating type of a core network connected thereto and sends the core network operating type information and information related to the core network to a hybrid type asynchronous terminal.
Herein, the CN Type. information and information related to core network are inserted into a master information block (MIB) in the system information message. In FIGS. 10A and 10B, views showing a format of the MIB are shown. The MIB has the CN Type information and the information related to core network in accordance with the present invention.
If the connected core network is the synchronous ANSI-41 core network, the RNC activates a synchronous. CC part and a synchronous MM part for MC at step S44 and then sets the core network operating type information CN Type corresponding to the detected core network operating type at step S45. For example, if the connected core network is the synchronous ANSI-41 core network, the RNC sets the CN Type information as “ANSI-41”.
As apparent from the. above description, according to the present invention, even though a hybrid type synchronous or asynchronous terminal is connected to either a GSM-MAP core network or an ANSI-41 core network, it can smoothly be interfaced with the connected core network because it is able to recognize the operating type of the connected core network and information related to the core network.
