A method, apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a hybrid type synchronous or asynchronous terminal to a core network in a next generation mobile telecommunications system. The hybrid type synchronous or asynchronous radio network determines the operating type of the core network when the core network has a connection thereto, and sends the determined core network operating type information and information related to the core network to the hybrid type synchronous or asynchronous terminal, thereby allowing the synchronous or asynchronous terminal to smoothly perform a data interfacing operation with the core network.
This application is a continuation of Ser. No. 09/564,941 filed May 4, 2000 now U.S. Pat. No. 6,741,868. The entire disclosure of the prior applications are considered as being part of the disclosure of the accompanying application and are hereby incorporated by reference therein by their entireties.
The present invention relates in general to a technique for interfacing among a mobile terminal, a base station (BS) and a core network in a next-generation mobile telecommunications system, and more particularly to a method, an apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a hybrid type mobile terminal, a hybrid type base transceiver station/base station controller (BTS/BSC) and a core network in a next-generation telecommunication system, e.g., an international mobile telecommunications-2000 (IMT-2000) system and so on, in which a hybrid type synchronous or hybrid type asynchronous radio network determines an operating type of the core network when the core network has a connection thereto, and sends information about the determined core network operating type and information related to the core network to a hybrid type mobile terminal.
In more detail, the present invention relates to a method, an apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a hybrid type mobile terminal, a hybrid type base transceiver station/base station controller (BTS/BSC) and a core network in a mobile telecommunications system, wherein a hybrid type synchronous radio network having a hybrid type BTS/BSC determines the operating type of the core network when the core network has a connection thereto, and sends the determined core network operating type and information related to the core network to the hybrid type synchronous terminal over a synchronous channel (Sync channel), and the hybrid type synchronous terminal recognizes the operating type of the core network on the basis of the core network operating type information (hereinafter, refers to “CN type”) and sets a protocol according to the information related to core network.
In a conventional synchronous mobile telecommunications system, a synchronous terminal is connected to a synchronous radio network (for example, a CDMA-2000 radio network), and an ANSI-41 network is connected to a core network.
After completing the above procedure, the synchronous terminal shifts to the synchronization sub-state S4.
the synchronization sub-state S4 is a state where the synchronous terminal synchronizes its timing with that of the selected CDMA system. The synchronous terminal synchronizes its timing with that of the selected CDA system on the basis of the information elements in the Sync channel message, received at the above Sync channel acquisition sub-state and stored in its memory. After being timed with the selected CDMA system, the synchronous terminal enters a standby mode S5.
The more detailed descriptions about layered protocol structures are well taught in 3rd Generation Partnership Project (3GPP), Technical Specification Group (TSG)-Radio Access Network (RAN) : 3G TS25.301 (Radio Interface Protocol Architecture), 3G TS25.302 (Services provided by the physical layer), 3G TS25.321 (MAC Protocol Specification), 3G TS25.322 (RLC Protocol Specification) and 3G TS25.331 (RRC Protocol Specification) in detail.
According to network deployment scenarios, the IMT-2000 system can have the following four interface architectures; first: synchronous terminal-synchronous radio network-synchronous ANSI-41 network, second: synchronous terminal-synchronous radio network-asynchronous GSM-MAP network, third: asynchronous terminal-asynchronous radio network-synchronous ANSI-41 network and fourth: asynchronous terminal-asynchronous radio network-asynchronous GSM-MAP network.
In other words, the conventional synchronous terminal and radio network have a disadvantage in that the synchronous terminal cannot be interfaced with any other networks than a synchronous core network connected thereto because it cannot recognize core network operating type information and core network related information.
Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a method, an apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a synchronous or asynchronous terminal, a synchronous or asynchronous radio network and a synchronous or asynchronous core network in a next-generation mobile telecommunications system.
In the specification, a radio network means a network including a plurality of base transceiver stations (BTS) and at least a base station controller for controlling the plurality of BTSs in a synchronous or an asynchronous mobile telecommunication system.
Functions for controlling the base transceiver station can be distributively performed in the plurality of the base transceiver stations, or can be concentrically performed in the base station controller. Therefore, in this specification, a terminology “base station,” which includes the base transceiver station and the base station controller, is used.
The layers 3 to 1 of the hybrid type synchronous radio network 110 are connected and correspond respectively to those in the hybrid type synchronous terminal 100 and those in the asynchronous core network 130. However, the NAS parts of the hybrid type asynchronous terminal 100 and the asynchronous core network 130 are coupled to each other not through the hybrid type synchronous radio network 110.
The hybrid type asynchronous terminal 210 comprises a layer 3 211, a layer 2 217 and a layer 1 218. The layer 3 includes a synchronous CC part 212, a synchronous MM part 213, an asynchronous CC part 214, an asynchronous MM part 215 and asynchronous RRC part 216 and selectively activates a synchronous CC/MM protocol or an asynchronous CC/MM protocol.
For example, if the hybrid type asynchronous terminal 210 is currently connected to the ANSI-41 core network 230, the layer 3 therein activates a protocol between the synchronous CC part 212 and synchronous MM part 213 to perform a message interfacing operation with the ANSI-41 core network 230.
The hybrid type asynchronous radio network 220 comprises a layer 3 221 having a NAS part and an AS part, a layer 2 225 and a layer 1 226, which activate their protocols corresponding respectively to those in the hybrid type synchronous terminal 210 and those in the GSM-MAP core network 240 to transmit and receive messages.
The layers 3 to 1 of the hybrid type asynchronous radio network 220 are connected and correspond respectively to those in the hybrid type asynchronous terminal 210 and those in the asynchronous core network 240. However, the NAS parts of the hybrid type asynchronous terminal 210 and the asynchronous core network 240 are coupled to each other not through the hybrid type asynchronous radio network 220.
In a method for interfacing a hybrid type synchronous terminal to a synchronous core network, the hybrid type synchronous mobile terminal and radio work have core network interface architectures as described above with reference to FIGS. 4A and 4B and the associated layered protocol structures as described above with reference to FIGS. 5A and 5B.
FIG. 8B is a block diagram of a terminal controller for interfacing the terminal with a core network, wherein the core network is of a synchronous or an asynchronous type.
The call processing unit 823 includes a receiving block which receives channel message having core network operating type information, and a determining block which extracts the core network operating type information inserted into a preselected location of the channel message and determines whether the core network is of a synchronous or an asynchronous type. The management/maintenance unit 825 includes a setting block which sets the terminal as an operating type corresponding to the core network operating type information. The controlling unit 821 performs general control functions of the terminal, for example, call processing function, management/maintenance function, etc. The terminal controller further includes a memory extracting and storing information related to the core network from the channel message. Here, the information related to the core network corresponds to the core network operating type information.
Herein, the CN Type information is set to “1” when the connected core network is the synchronous ANSI-41 core network, and “0” when the connected core network is the asynchronous GSM-MAP core network.
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.
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.
Herein, the core network operating type information is used to indicate whether the core network connected to the synchronous radio network is the ANSI-41 network or the GSM-MAP network. For example, the core network operating type information is set to “1” when the core network connected to the hybrid type synchronous radio network is the ANSI-41 core network, and “0” when the connected core network is the GSM-MAP core network.
Subsequently, the hybrid type synchronous terminal analyzes core network operating type information CN Type among information elements in the received Sync channel message at step S25. Herein, the CN Type information is set to “1” when the connected core network is the synchronous ANSI-41 core network, and “0” when the connected core network is the asynchronous GSM-MAP core network.
Accordingly, the hybrid type synchronous terminal determines at step S26 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).
On the other hand, in the case where it is determined at the above step S26 that the CN Type information value is not “1”, the synchronous terminal determines at step S31 whether the CN Type information value is “0” and proceeds to step S32 if the CN Type information value is “0”. At step S32, the synchronous terminal analyzes the information elements related to core network as those for the GSM-MAP core network and stores a desired one, a PLMN identity, of them in its memory.
Architectures of telecommunication system for interfacing a hybrid type asynchronous terminal with a core network are described above with reference to FIGS. 4C and 4D and the associated layered protocol structures of the telecommunication system are described above with reference to FIGS. 5C and 5D.
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 it is determined at the above step S42 that the connected core network is the asynchronous GSM-MAP core network, the hybrid type RNC sets core network operating type information CN Type corresponding to the detected operating type of the core network at step S45. For example, if the connected core network is the asynchronous GSM-MAP core network, the RNC sets the core network operating type information as “GSM-MAP”.
In FIGS. 10A and 10B, other fields except for CN information elements are the same as those in the conventional system information message shown in FIG. 7B and a detailed description thereof will thus be omitted. The core network operating information and the information related to core network are written in the CN information element field. Because it is determined at the above step S42 that the connected core network is the asynchronous GSM-MAP core network, “GSM-MAP” is written in the CN Type information field and a PLMN identity is written in the core network related information field.
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”.
Subsequently, the RNC inserts the set CN Type information and the in formation related to core network respectively into specific fields of a system information message at step S46.
In FIGS. 10C and 10D, other fields except for fields containing CN information elements are the same as those in the conventional system information message shown in FIG. 7B and a detailed description thereof will thus be omitted. The CN Type information and information related to core network are written in the CN information element fields. Because it is determined at the above step S43 that the connected core network is the synchronous ANSI-41 core network, “ANSI-41” is written in the CN Type information field and ANSI-41 information elements are written in the information related to core network field. Herein, the ANSI-41 information elements are P_REV, MIN_P_REV, SID and NID information.
The hybrid type asynchronous terminal determines at step S55 whether the CN Type information is “GSM-MAP” and proceeds to step S56 if the CN Type information is “GSM-MAP”. At step S56, the hybrid type asynchronous terminal analyzes the information elements related to core network as those for the GSM-MAP core network and stores a desired one, a PLMN identity, of them in its memory.
On the other hand, in the case where it is determined at the above step S55 that the CN Type information is not “GSM-MAP”, the hybrid type asynchronous terminal determines at step S60 whether the CN Type information is “ANSI-41” and proceeds to step S61 if the CN Type information is “ANSI-41 ”.
Thereafter, at step S62, the hybrid type asynchronous terminal selects a synchronous CC part and a synchronous MM apart for the ANSI-41 network and sets a protocol therebetween. Subsequently, the hybrid type asynchronous terminal carries out its initialization based on the contents of the core network related information elements at step S63 and then performs a message interfacing operation with the ANSI-41 core network at step S64.
