Upon initial power-up of the hybrid terminal 200 in the mobile communication system 100 for the high speed data communication (HDR), the hybrid terminal 200 detects received field sensitivity of neighboring base stations through a pilot channel.

The hybrid terminal 200 that successfully registers the terminal and authenticates the subscriber attempts to connect to the HDR access point 121 in order to be assigned a unicast access terminal identifier (UATI) used for high-speed data communication, and then assigns the UATI to the corresponding UATI. The hybrid terminal 200 transitions to an idle, that is, a standby state through a process of communicating a session between the hybrid terminal 200 and the mobile communication system 100.

In relation to the unicast access terminal identifier (UATI) allocation, since it is a conventional technique that is known and implemented in various ways before this application, a detailed description thereof will be omitted.

However, in the related art, despite the state where the HDR access point 121 is no longer able to receive a connection, the unicast access terminal identifier used by the hybrid terminal 200 that has successfully registered the terminal and registered the subscriber is used for high-speed data communication. Since an initial call connection is attempted to the HDR access point 121 in order to be allocated, a problem of unnecessary power consumption of the hybrid terminal and unnecessary load generation of the base station controller (BTC) is caused in this process.

Therefore, the present inventors connect the High Data Rate (HDR) network module for UATI (Unicast Access Terminal Identifier) allocation used for high-speed data communication after the IS-95 / 1x network module is synchronized with the initial power-up of the hybrid terminal. If there is no resource available to access the HDR access point in advance, limiting attempts to access data communication through the HDR access point for a predetermined time prevents unnecessary power consumption of the hybrid terminal and unnecessary load generation of the base station controller (BTC). The research on the communication connection limiting system and method of the hybrid terminal that can be prevented.

The present invention has been invented under the above-described purpose, and after the IS-95 / 1x network module is synchronized with the initial power-up of the hybrid terminal, HDR (Unicast Access Terminal Identifier) for UATI allocation used for high-speed data communication is high. Data Rate) The present invention provides a system and method for restricting communication access of a hybrid terminal that restricts data communication access attempts through an HDR access point for a predetermined time when there is no accessible HDR access point resource before accessing a network module.

According to an aspect of the present invention for achieving the above object, the communication connection limiting system and method of the hybrid terminal according to the present invention, after the initial power-up of the hybrid (Hybrid) terminal after the synchronization of the IS-95 / 1x network module, Before accessing the High Data Rate (HDR) network module for unicast access terminal identifier (UATI) allocation used for data communication, it is determined whether there is an accessible HDR access point resource from an overhead message, and the accessible HDR access is available. When there is no point free resource, it is characterized in that the attempt to block data communication through the HDR access point for a certain time.

Therefore, after the initial power-up of the hybrid terminal, the IS-95 / 1x network module is synchronized and connected prior to accessing the high data rate (HDR) network module for unicast access terminal identifier (UATI) allocation used for high-speed data communication. In the absence of possible HDR access point spare resources, it is possible to prevent unnecessary hybrid power consumption and unnecessary load of the base station controller (BTC) by limiting data communication connection attempts through the HDR access point for a certain period of time. Will be.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce the present invention.

2 is a schematic diagram of a communication connection restriction system of a hybrid terminal according to the present invention.

The communication connection limiting system 300 of the hybrid terminal according to the present invention exists in the form of software executable in the hybrid terminal 200 supporting the IS-95 / HDR dual mode, when the initial power of the hybrid terminal is applied. After synchronization of the IS-95 / 1x network module, and there is no accessible HDR access point spare resource before accessing the High Data Rate (HDR) network module for unicast access terminal identifier (UATI) allocation used for high-speed data communication. By implementing the data communication connection attempt through the HDR access point for a certain period of time, it is possible to prevent unnecessary power consumption of the hybrid terminal and unnecessary load of the base station controller (BTC).

In the present invention, the determination of whether there is a spare resource of the HDR access point is performed by using the information included in the overhead message transmitted periodically from the IS-95 / 1x BTS 111 to the hybrid terminal 200. Judging by reference.

When system synchronization is acquired between the hybrid terminal 200 and the base station IS-95 / 1x BTS 111, the hybrid terminal 200 periodically transmits an overhead message transmitted by the IS-95 / 1x BTS 111. Receive

The overhead message indicates that the mobile communication system 100 provides the hybrid terminal 200 with detailed information of the base station (location of the base station, base station identifier, operating frequency of the base station, handoff operation information), and details of neighboring base stations. To provide general information, channel information used by the current base station, registration area information of the hybrid terminal, user area information for Tiered Service, information required for the hybrid terminal to access the base station, and the like. This message is sent periodically.

The HDR access point 121, which is separately or embedded in the IS-95 / 1x BTS 111 that provides a high speed data transfer (HDR) service, uses a traffic channel to the connected hybrid terminals 200 to provide a data service. Each of these traffic channels is identified by a different MAC Index. The HDR access point 121 spreads using a Walsh code corresponding to each MAC index and transmits the data to the hybrid terminal 200.

Currently, the mobile communication system for high speed data communication supports 64 MAC indexes, and 59 of the 5 to 63 traffic channels except 0 to 4 are used for special purposes. Perform data services.

In the overhead message, information indicating how many hybrids 200 are connected to the HDR access point 121 accessible at the current location to enable data service toward the forward, that is, accessible at the current location A QuickConfig message with the MAX Index information of the HDR access point is included.

Accordingly, the communication access limiting system 300 of the hybrid terminal according to the present invention is a unicast access terminal identifier (UATI) used for high-speed data communication after synchronizing an IS-95 / 1x network module at the time of initial power-up of the hybrid terminal. Prior to accessing the HDR (High Data Rate) network module for allocation, it is determined by referring to Max Index information of the accessible HDR access point of the QuickConfig message, if there is an accessible HDR access spare resource. If this does not exist, blocking attempts to connect data communication through the HDR access point for a certain time prevents unnecessary power consumption of the hybrid terminal and generation of unnecessary load of the base station controller BTC.

With reference to Figure 3 looks at the specific configuration of the communication access restriction system 300 of the hybrid terminal according to the present invention.

3 is a block diagram of one embodiment of a communication connection restriction system of a hybrid terminal according to the present invention.

As shown in the figure, the communication access restriction system 300 of the hybrid terminal according to the present invention includes a margin resource determination unit 310 and the data communication blocking unit 320.

The spare resource determination unit 310 determines whether there is an accessible HDR access point resource from the received overhead message.

Upon initial power-up of the hybrid terminal 200, the hybrid terminal 200 detects reception field sensitivity of neighboring base stations through a pilot channel and uses a sync channel to a base station having the largest reception field sensitivity. After the synchronization, the terminal location registration and subscriber authentication request information is transmitted to the IS-95 / 1x BTS 111 to request terminal location registration and subscriber authentication.

The terminal location registration and subscriber authentication request information are transmitted to the MSC 113 via the BTC 112 to perform a terminal location registration procedure through the HLR 114 interworking with the MSC 113, and the AUC 115. ), The subscriber authentication process is performed.

The hybrid terminal 200 that successfully registers the terminal and authenticates the subscriber attempts to access a call to the HDR access point 121 to be allocated a unicast access terminal identifier (UATI) used for high-speed data communication. The communication access restriction system 300 of the hybrid terminal according to the present invention periodically transmits an overhead message from the IS-95 / 1x BTS 111 to the hybrid terminal 200 through the spare resource determination unit 310. It is determined whether there is an accessible HDR access point resource with reference to the information included in the.

At this time, the spare resource determination unit 310 has a spare resource of the HDR access point accessible from the QuickConfig message including the MAX Index information of the HDR access point accessible at the current position of the received overhead message information Determine.

The data communication blocker 320 determines that there is no HDR access point spare resource accessible by the spare resource determiner 310, the data of the HDR task stage managing the HDR connection for a predetermined time. Set Call Origination to Fail to block data communication attempts through the HDR access point.

That is, when it is determined that the spare resource of the accessible HDR access point exists by the spare resource determining unit 310, the hybrid terminal 200 receives a unicast access terminal identifier (UATI) used for high-speed data communication. Attempts to connect to the HDR access point 121, and after the allocation of the UATI, undergoes a process of negotiating a session between the hybrid terminal 200 and the mobile communication system 100 with respect to the corresponding UATI. (Idle) In other words, transition to the standby state.

On the other hand, when it is determined by the free resource determining unit 310 that there is no free resource of the accessible HDR access point, the communication connection limiting system 300 of the hybrid terminal according to the present invention is the data communication blocking unit 320 In this example, Data Call Origination of the HDR Task stage that manages the HDR connection is set to Fail to block data communication attempts through the HDR access point.

The HDR task is executed under the control of an operating system to manage the HDR connection. The HDR task attempts or blocks data communication through the HDR access point by referring to the setting value of the Data Call Origination field during the HDR connection processing. That is, the HDR task processes the data communication connection through the HDR access point when the Data Call Origination field value is Success, and prevents data communication attempt through the HDR access point when Fail.

Accordingly, the communication access restriction system 300 of the hybrid terminal according to the present invention analyzes the overhead message through the spare resource determination unit 310 to determine whether there is an accessible HDR access point resource and accesses it. If it is determined that there is no available HDR access point free resource, the HDR access point is set by setting the data call origination of the HDR task stage that manages the HDR connection to Fail through the data communication blocking unit 320 for a predetermined time. By blocking data communication attempts, unnecessary power consumption of the hybrid terminal and unnecessary load of the base station controller (BTC) are prevented.

On the other hand, according to an additional aspect of the present invention, the communication access restriction system 300 of the hybrid terminal according to the present invention may further include a data communication active unit 330.

The data communication activator 330 monitors an overhead message when a data communication attempt through the HDR access point is blocked by the data communication blocking unit 320 for a predetermined time, and monitors an overhead message. Enable access to data communication through the HDR access point when there is an accessible HDR access point spare resource.

That is, in this case, it is determined that there is no accessible HDR access point free resource, and when there is an accessible HDR access point free resource while the data communication attempt through the HDR access point is blocked for a predetermined time, the data communication through the HDR access point is performed. Enable this to resume data communication.

To this end, the communication connection limiting system 300 of the hybrid terminal according to the present invention, when the data communication attempt through the HDR access point for a predetermined time by the data communication blocking unit 320, the data communication active unit ( In step 330, the variable Cannot_Supprot_hdr_flag, which is a variable for resuming data communication through the HDR access point, is set to True and the overhead message is monitored to monitor whether there is an accessible HDR access point free resource.

If the value of Cannot_Supprot_hdr_flag is True, the data communication attempt through the HDR access point is blocked and the connection is induced through the IS-95 / 1x BTS 111. If False, the data communication attempt through the HDR access point is possible. Is a variable for resuming data communication through the HDR access point.

If, as a result of monitoring the overhead message through the data communication activation unit 330 (Mornitoring), when there is no accessible HDR access point spare resource for the predetermined time, the Cannot_Supprot_hdr_flag is set to False and the initial state Reduced to.

However, if there is an HDR access point spare resource that can be accessed during monitoring of an overhead message through the data communication activator 330, the communication access restriction system 300 of the hybrid terminal according to the present invention. The terminal forcibly terminates the timer through the data communication activator 330 and sets the Cannot_Supprot_hdr_flag to False to enable data communication through the HDR access point.

Therefore, the communication connection limiting system 300 of the hybrid terminal according to the present invention is active to enable data communication through the HDR access point when an accessible HDR access point spare resource is generated while the data communication attempt through the HDR access point is blocked. This allows more efficient high speed data communication connection control.

The communication connection restriction method of the hybrid terminal according to the present invention having the above configuration will be described in detail with reference to FIG. 4.

4 is a flowchart illustrating a communication connection restriction method of a hybrid terminal according to the present invention.

First, after synchronizing the IS-95 / 1x network module upon initial power-up of the hybrid terminal, prior to accessing the high data rate (HDR) network module for unicast access terminal identifier (UATI) allocation used for high-speed data communication, The overhead message information received through the overhead message analysis step S110 is analyzed.

After analyzing the overhead message information, the spare resource of the accessible HDR access point with reference to the QuickConfig message including the MAX Index information of the HDR access point accessible from the current location through the free resource determination step (S120) Determine if it exists.

If it is determined by the free resource determination step (S120) that no accessible HDR access point free resource exists, an HDR task stage for managing the HDR connection for a predetermined time through the data communication blocking step (S130). Set Data Call Origination to Fail to block data communication attempts through the HDR access point.

Therefore, after the initial power-up of the hybrid terminal, the IS-95 / 1x network module is synchronized and connected prior to accessing the high data rate (HDR) network module for unicast access terminal identifier (UATI) allocation used for high-speed data communication. In the absence of possible HDR access point spare resources, it is possible to prevent unnecessary hybrid power consumption and unnecessary load of the base station controller (BTC) by limiting data communication connection attempts through the HDR access point for a certain period of time. Will be.

On the other hand, when the data communication blocking step (S130) is blocked attempts to communicate data through the HDR access point for a certain period of time (Mornitoring) an overhead message (Mornitoring), and access to the HDR access point spare resources available during monitoring And when present, may further comprise enabling data communication via the HDR access point.

Therefore, when an accessible HDR access point spare resource is generated while the data communication attempt via the HDR access point is blocked, the data communication through the HDR access point is enabled to enable more efficient high speed data communication connection control.

By doing so, the communication connection limiting system and method of the hybrid terminal according to the present invention can achieve the object of the present invention described above.
