In addition, the asynchronous terminal 60 receives a system information message (System Information Message) from the UTRAN 70 through a broadcast control channel (BCCH), through which the asynchronous terminal including core network information or UTRAN information Information necessary for access to the network is obtained.

On the other hand, in the case of the synchronous / asynchronous method of the IMT-2000 system, a GSM-MAP network that is used asynchronously or an ANSI-41 network that is used synchronously may be used as the core network according to the May 1999 OHG requirement decision. .

That is, the IMT-2000 system may have the following four interworking structures according to the network deployment situation.

In this interworking structure, the synchronization terminal 100 is divided into a layer 3 (101), a layer 2 (106), a layer 1 (107), and the layer 3 (101) is a sync CC (102), a sync MM (103), Both asynchronous CC 104 and asynchronous MM 105 are provided, and the protocol of the CC / MM is selectively activated according to the network identifier (a code for identifying the type of network).

For example, since the currently connected network is the ANSI-41 core network 120, the protocols of the synchronous CC 102 and the synchronous MM 103 are activated to interface the message with the ANSI-41 core network 120.

Next, the synchronous wireless network 110 is composed of layer 3 (111), layer 2 (112), layer 1 (113), each layer of the synchronization terminal 100 and each layer of the ANSI-41 core network 120 Corresponds to the message by activating the protocol.

Next, the synchronous wireless network 110 is composed of layer 3 (111), layer 2 (112), layer 1 (113), each layer of the synchronization terminal 100 and each layer of the GSM-MAP core network 130 Corresponds to the message by activating the protocol.

In addition, the GSM-MAP core network 130 is divided into a NAS unit 131, a layer 3 134, a layer 2 135, and a layer 1 136, and the NAS unit 131 is an asynchronous CC ( 132, an asynchronous MM 133.

4C is a protocol hierarchy diagram of an asynchronous terminal interworking with the ANSI-41 core network, where reference numeral 210 is an asynchronous terminal, 220 is an UTRAN which is an asynchronous wireless network, and 230 is connected to the UTRAN 220 which is the asynchronous wireless network.

For example, since the currently connected network is the ANSI-41 core network 230, the protocols of the synchronous CC 211 and the synchronous MM 212 are activated to interface the message with the ANSI-41 core network 230.

Next, FIG. 4D shows a protocol hierarchy diagram of an asynchronous terminal interworking with a GSM-MAP core network.

Here, reference numeral 210 denotes an asynchronous terminal, 220 denotes UTRAN which is an asynchronous wireless network, and 240 denotes a GSM-MAP core network which is connected to the UTRAN 220 which is the asynchronous wireless network.

In this protocol structure, the asynchronous terminal 210 includes all of the synchronous CC 211, the synchronous MM 212, the asynchronous CC 213, and the asynchronous MM 214, and optionally the synchronous CC / MM or the asynchronous CC / MM. Activate the protocol.

For example, since the currently connected network is the GSM-MAP core network 240, the protocols of the asynchronous CC 213 and the asynchronous MM 214 are activated to interface the message with the GSM-MAP core network 240.

As described above, since the IMT-2000 system synchronous / asynchronous system can have four interworking structures, the interface specification should be applied correspondingly.

That is, between the synchronous terminal and the synchronous wireless network is called Air-Interface, uses the same communication protocol as IS-2000, and between the synchronous wireless network and the ANSI-41 network, which is the core network, is called A-Interface, and 3G-IOS (3 Use communication protocols such as Generation Interoperability Specification.

On the other hand, when the IMT-2000 system is a structure in which the asynchronous communication method, that is, the asynchronous terminal and the asynchronous communication wireless network and the GSM-MAP core network interworking, the asynchronous communication wireless network and the asynchronous terminal mutually communicate the RRC protocol entity It interoperates with and exchanges messages used by RRC protocol entities. The RRC protocol entity is a protocol entity that manages and controls radio resources between an asynchronous communication wireless network and a terminal. The management and control of radio resources is a message defined in the RRC protocol entity. RRC Message "). If these RRC messages are classified by function, they are as follows.

1) RRC Message related to RRC Connection Management.

That is, the RRC messages responsible for connection and release for asynchronous communication wireless network and the RRC protocol entities of the terminal are connected to each other, the basic operations used after the RRC connection is connected, and the functions broadcasted to the terminal. Say.

2) RRC Message related to Radio Bearer.

That is, RRC messages that perform functions related to radio resources such as radio resource allocation and reconfiguration of radio resources between asynchronous communication radio networks and terminals.

3) RRC message related to RRC connection mobility.

That is, it refers to RRC messages that perform functions related to mobility information and handover.

4) RRC Message related to Measurement Control.

That is, RRC messages that perform functions related to the current configuration of the radio resources and the current state measurement and management of the radio resources in order to efficiently use the resources.

RRC messages that perform the functions described above include the following information elements according to the function or purpose of each RRC message.

1) Information elements related to core network information

2) UTRAN mobility information-related information elements

3) UE information related information elements

4) Information element related to Radio Bearer information

5) information element related to transport channel information

6) Information element related to physical channel information

7) Information element related to measurement information

Some or all of these information elements are included in each RRC message, and each information element includes many information fields. Among the many information fields in each information element, all or part of the information field is included depending on the function and use, and are interchanged between the wireless network and the terminal of the asynchronous communication method.

The wireless network and the asynchronous terminal of the asynchronous communication method are included in the RRC messages exchanged between the asynchronous wireless network and the terminal. Among the information elements transmitted and transmitted, the information elements related to the radio resource information are stored and used in the RRC protocol entity. Information elements related to core network information or information not related to radio resources are stored and used by CC and MM protocol entities existing in Layer3.

The RRC messages described above, the information elements included in each RRC message, and the information fields included in each information element are defined for asynchronous communication.

As the IMT-2000 system of the asynchronous communication method has a linkage structure between the asynchronous terminal, the wireless network of the asynchronous communication method, and the GSM-MAP core network, according to the network development situation, the asynchronous terminal has an asynchronous CC, MM protocol. The entity operates and the messages exchanged between the asynchronous radio network and the terminal use the RRC messages and other asynchronous messages described above, and the radio resource uses the radio resource used in the asynchronous communication method. Accordingly, in this interworking structure, the wireless network and the terminal of the asynchronous communication method are information elements related to the radio resource among the information elements transmitted and included in the RRC message exchanged between the asynchronous wireless network and the terminal as described above. They store and use in the RRC protocol entity, and information elements related to the core network or information not related to radio resources are stored and used in the CC, MM protocol entity in the upper layer.

In addition, in the case of the IMT-2000 system having such an interworking structure, the CC and MM protocol entities that perform functions such as call control and mobility management are also asynchronous, and asynchronous communication wireless network and terminal Since the RRC messages, information elements, and information fields exchanged between are defined according to the asynchronous communication method, they perform functions such as call control and mobility management without any problems. GSM-MAP core network can be interworked.

On the other hand, according to the results of the OHG requirement, if the asynchronous communication type IMT-2000 system has an interworking structure of the asynchronous terminal, the asynchronous communication type wireless network, and the ANSI-41 core network according to the network development situation, The CC and MM protocol entities operate, and the messages exchanged between the asynchronous radio network and the terminal use the RRC messages and other asynchronous messages described above, and the radio resource uses the radio resource used in the asynchronous communication method. do. In addition, the wireless network and the asynchronous terminal of the asynchronous communication method in such an interworking structure, as is well known, in the interworking structure of the IMT-2000 system having an interworking structure of the asynchronous terminal, the asynchronous communication wireless network and the GSM-MAP core network Interchange and process RRC Messages in the same way as used.

However, such an interlocking structure causes a problem. That is, the information fields included in the RRC messages exchanged between the asynchronous wireless communication network and the asynchronous terminal are not considered such an interworking structure.

In this interworking structure, in order for a synchronous CC and MM protocol entity operating in an asynchronous terminal to normally operate functions such as call control and mobility management, core network information is included among information elements included in RRC messages. Information elements related to or information elements not related to a radio resource should include an information field used by a synchronous CC and MM protocol entity.

However, since the RRC messages, information elements included in the RRC messages, and information fields included in the information elements exchanged between the asynchronous communication wireless network and the asynchronous terminal are all defined for the asynchronous communication method, , Synchronous CC, MM protocol entities cannot use it. If the current information elements and information fields are used as they are, in the IMT-2000 system having such an interworking structure, the asynchronous terminal cannot normally interwork with the ANSI-41 core network.

Accordingly, the present invention has been proposed in order to solve various problems that occur when the synchronous core network is connected and interworked in the conventional asynchronous mobile communication system.

It is an object of the present invention to smoothly transmit an RRC message between an asynchronous terminal and an asynchronous wireless network regardless of the type of core network to be connected (asynchronous core network GSM-MAP core network and synchronous core network ANSI-41 core network). The present invention provides a method for transmitting a radio resource control message in a mobile communication system.

The present invention for achieving the above object,

When the core network connected to the asynchronous wireless network in the asynchronous mobile communication system is the GSM-MAP network, which is an asynchronous core network, the core among several information elements included in the RRC messages exchanged between the asynchronous communication wireless network and the asynchronous terminal Information fields included in network-related information elements and information elements not related to radio resources use the RRC message used in the existing asynchronous system.

In addition, when the core network connected to the asynchronous wireless network in the asynchronous mobile communication system is the ANSI-41 network, which is a synchronous core network, the information related to the core network and the information elements not related to the radio resources in the asynchronous RRC message are synchronous new information. Changed to the field and transmitted, the radio resource related information elements use the existing asynchronous RRC message as it is so that the RRC message transmission.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention according to the technical spirit as described above.

According to the present invention, among information fields included in existing RRC messages used in an asynchronous system, information fields depending on the type of the core network, that is, an information field to be changed by the type of the core network, are assigned to the type of the core network. According to the modification, the normal operation is always performed regardless of the type of the core network to which the CC and MM protocol entities in the layer 3 of the asynchronous terminal are linked.
