Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a diagram illustrating a communication system including a base station apparatus and a network apparatus according to a preferred embodiment of the present invention.

1, a communication system including a base station apparatus and a network apparatus according to the present invention includes a plurality of base stations 100 and 200 for providing a communication service to a terminal connected thereto, and a network apparatus 300 .

The plurality of base stations 100 and 200 may include a small base station constructing a small cell such as a femtocell or a picocell, and a macro base station constructing a macro cell, and each base station included in the plurality of base stations 100 and 200 may include a single cell Or a plurality of cells may be formed.

Hereinafter, for convenience of description, a plurality of base stations 100 and 200 will be referred to as a first base station 100 and a second base station 200, and a first base station 100 will be referred to as a plurality of cells (e.g., ) And the second base station 200 forms a single cell (e.g., cell 3). In this case, the first base station 100 and the second base station 200 may be a base station apparatus according to the present invention.

When the UE 10 is connected to the cell 1 of the first base station 100 and the cell 1 of the cell 2, the first base station 100 transmits an Initial UE message including identification information related to the cell 1, To the device (300). The network device 300 registers location information indicating to which cell the terminal 10 is connected based on the identification information associated with the cell 1 included in the initial terminal message, The information registration procedure can be performed.

Here, the above-described identification information may be information that can identify the base station and the cell, and may be information composed of base station identification information (e.g., base station ID) and cell identification information (e.g., cell ID). That is, the identification information included in the initial terminal message provided from the first base station 100 may be information composed of the base station ID of the first base station 100 and the cell ID of the cell 1.

For example, such identification information may be an E-UTRAN Cell Global Identifier (ECGI).

In this way, when the terminal 10 is connected to the cell 1 of the first base station 100, the cell of the first base station 100, which is received by the terminal 10 due to the movement of the terminal 10 or the change of the radio environment, 1 and the signal strength of other cells is relatively large, the terminal 10 performs handover from the currently connected cell 1 to another cell. That is, the terminal 10 performs inter-cell handover.

Here, the inter-cell handover in which the UE 10 is handed over from the cell 1 currently connected, that is, from the source cell to another cell, that is, the target cell, can be largely divided into two types.

That is, in the case of the base station handover in which the terminal 10 is handed over from the cell 1 of the first base station 100 to another cell (e.g., cell 2) of the same first base station 100, 1 handover from a cell 1 of a first base station 100 to a cell of another second base station 200 (e.g., cell 3).

Herein, the inter-cell handover procedure in which the UE 10 performs handover from a cell 1 to another cell (e.g., cell 2 of the same first base station 100 or cell 3 of another second base station 200) , The conventional handover procedure is followed, and a detailed description thereof will be omitted.

However, in the case of a base station handover in which the UE 10 is handed over from a cell 1 of the first base station 100 to another cell (e.g., cell 2) of the same first base station 100, A separate message provided to the network device 300 by the first base station 100 of the target cell does not occur during the handover process.

However, in the case of inter-base station handover in which the UE 10 is handed over from a cell 1 of the first base station 100 to a cell of another second base station 200 (e.g., cell 3) A separate message to be provided to the network device 300 by the second base station 200 of the target cell is generated during the handover process because the message is changed from the first base station 100 to the second base station 200, And identification information related to the target cell, i.e., cell 3, to which the terminal 10 is handed over.

As described above, when the terminal 10 is handed over from cell 1 to another cell (e.g., cell 2 or cell 3), the network device 300 transmits identification information related to the handed-over cell (e.g., cell 2 or cell 3) The location information registration procedure is performed for the terminal 10 by updating the location information of the terminal 10 based on the location information.

In this case, the base station apparatus and the network apparatus according to the present invention may be applied to a terminal 10 performing an inter-cell handover due to the fact that a separate message is generated in the handover process in the case of handover between base stations as described above, The location information reporting procedure and the location information registration procedure for updating the location information of the base station apparatus and the network apparatus are reduced.

To this end, the base station apparatus according to the present invention, that is, the first base station 100 or the second base station, confirms the type of handover to the terminal 10 handed over from the source cell to the target cell.

For example, the base station apparatus according to the present invention will be a base station of a target cell, with reference to a terminal 10 handed over from a source cell to a target cell.

Therefore, when referring to the case of a base domestic handover in which the terminal 10 is handed over from cell 1 of the first base station 100 to another cell (e.g., cell 2) of the same first base station 100, The base station apparatus according to the present invention may be a base station apparatus of the target cell, that is, the first base station 100. Meanwhile, referring to the case of inter-base station handover in which the UE 10 is handed over from a cell 1 of the first base station 100 to a cell of another second base station 200 (e.g., cell 3) The base station apparatus may be a base station apparatus of the target cell, that is, the second base station 200.

As described above, the base station apparatus of the present invention, that is, the base station apparatus of the target cell, confirms the type of handover to the terminal 10 handed over from the source cell to the target cell. Hereinafter, for convenience of description, the first base station 100 will be referred to as a base station apparatus according to the present invention.

Accordingly, the first base station 100 confirms the type of handover to the terminal 10 handed over from the source cell to the target cell.

That is, the first base station 100 confirms whether the type of handover to the terminal 10 handed over to its own cell is a base domestic handover or an inter-base station handover.

Then, the first base station 100 performs the position information reporting procedure related to the target cell differently for the terminal 100, according to the kind of the confirmed handover.

Meanwhile, the network device 300 according to the present invention confirms the type of handover to the terminal 10 handed over from the source cell to the target cell.

That is, the network device 300 confirms whether the type of the handover to the terminal 10 handed over from the source cell to the target cell is a base domestic handover or an inter-base station handover.

Accordingly, the network device 300 performs the location information registration procedure related to the target cell differently for the terminal 10, depending on the type of the confirmed handover.

The network device 300 may be a mobility management entity (MME) that is located in the core network and is responsible for signal control of the base station and determines routing of data transmission to the terminal.

Hereinafter, the configuration of a base station apparatus according to a preferred embodiment of the present invention will be described in more detail with reference to FIG. For convenience of explanation, the reference numbers of the first base station 100 will be described.

The base station apparatus 100 according to the present invention includes a handover type checking unit 110 for checking the type of handover to a terminal handed over from a source cell to a target cell, And a location information reporting unit 120 for performing location information reporting procedures related to the target cell differently from the terminal.

The handover type confirmation unit 110 confirms the type of handover to the terminal handed over from the source cell to the target cell.

That is, the handover type checking unit 110 can confirm the type of the handover to the terminal 10 when the terminal 10 to be handed over is identified as a cell of the base station 100 as a target cell.

At this time, the type of handover may be base domestic handover or inter-base station handover.

That is, if the terminal 10 is handed over from the cell 1 of the source cell, such as the base station 100, to another cell 2 of the target cell, for example, the base station 100, 10), the type of handover will be confirmed by the base domestic handover.

On the other hand, if the terminal 10 is handed over from the cell 3 of the source cell, for example, the second base station 200, to the cell 2 of the target cell, for example, the base station 100, The mobile station 10 will check the type of handover by inter-base station handover.

The location information reporting unit 120 performs location information reporting procedures related to the target cell differently for the terminal 10 according to the type of handover confirmed by the handover type checking unit 110. [

More specifically, the location information reporting unit 120 notifies the terminal 10 of identification information related to the target cell only when the type of the handover confirmed by the handover type checking unit 110 is a base domestic handover And performs a location information reporting procedure separately provided to the network device 300.

For example, the location information reporting unit 120 may determine that the target cell (e.g., cell 1 - > cell 2) is a target cell only when the type of handover confirmed by the handover type checking unit 110 is a base domestic handover (Location Report Message) including the identification information (e.g., ECGI) associated with the cell 2 (cell 2) to the network device 300 separately.

The network device 300 confirms identification information (e.g., ECGI) related to the target cell (e.g., cell 2) to which the terminal 10 has been handed over in the location information report message received separately from the base station device 100 And updates the location information of the terminal on the basis of the location information.

Meanwhile, when the kind of the handover confirmed by the handover type checking unit 110 is inter-base station handover (e.g., cell 3 -> cell 2), the location information reporting unit 120 reports the location information The network device 300 does not separately provide a message.

More specifically, in the case where the terminal 10 performs inter-base station handover as inter-cell handover (for example, cell 3 -> cell 2) as described above, The base station apparatus 100 of FIG. 2 provides a separate message to the network apparatus 300.

For example, when the handover complete message is received from the terminal 10 performing the inter-base station handover (e.g., cell 3 -> cell 2), the base station apparatus 100 of the cell 2 transmits the handover complete message ) To the target cell, that is, the base station apparatus 100 of the cell 2, from the second base station 200 of the source cell, that is, the cell 3, (300).

At this time, the path change request message includes identification information (e.g., ECGI) related to cell 2.

Therefore, when the type of the handover confirmed by the handover type checking unit 110 is inter-base station handover (for example, cell 3 -> cell 2), the location information reporting unit 120 separately transmits the location information report message So that the network device 300 can perform the location information registration procedure for the terminal 10 using the route change request message generated in the handover process for the terminal 10 instead of providing the route change request message to the network device 300 do.

When the terminal 10 performs inter-base-station handover (for example, cell 3 - > cell 2), the network device 300 transmits a path change request message received during the handover process to the target cell The location information registration procedure for the terminal 10 can be performed based on the obtained identification information.

Hereinafter, a configuration of a network device according to a preferred embodiment of the present invention will be described in more detail with reference to FIG.

The network device 300 according to the present invention includes a handover type checking unit 310 for checking the type of the handover from a source cell to a target cell handed over from the source cell to the target cell, And a location information registration unit 320 for performing a location information registration procedure related to the target cell differently from the terminal.

Hereinafter, for convenience of description, it is assumed that the terminal 10 is connected to the cell 1 of the first base station 100 as a source cell.

The handover type checking unit 310 determines the type of handover for the terminal 10 handed over from the cell 1 of the source cell, i.e., the first base station 100, to the target cell (e.g., cell 2 or cell 3) Check.

That is, when the terminal, i.e., the terminal 10 in which the inter-cell handover is performed among the terminals where the location information is pre-registered in the network device 300 is confirmed, You can check the type of handover.

At this time, the type of inter-cell handover is a type of inter-cell handover in which a terminal 10 is handed over from a source cell, that is, a cell 1 of the first base station 100, to another cell 2 of a target cell, Or the inter-base station handover in which the terminal 10 is handed over to the cell 3 of the source cell, that is, the cell 1 of the first base station 100, to the cell 3 of the target cell such as another second base station 200.

The handover type checking unit 310 determines whether the handover is to be handed over from the cell 1 of the source cell, i.e., the first base station 100, to the target cell (e.g., cell 2 or cell 3) It is checked whether the type is the base domestic handover or the inter-base-station handover.

At this time, the handover type checking unit 310 confirms that it is a base domestic handover when the location information report message is received from the base station of the target cell to the terminal 10 that has performed the inter-cell handover, 10) is received from the base station of the target cell, it can be confirmed that the handover is inter-base-station handover.

The location information registration unit 320 performs the location information registration procedure related to the target cell differently to the terminal 10 according to the type of the handover confirmed by the handover type checking unit 310. [

More specifically, the location information registering unit 320 registers the location information of the first terminal 100 including the identification information related to the cell 1 from the first base station 100 as the terminal 10 is connected to the cell 1 of the first base station 100, Upon receiving the message, the location information registration procedure can be performed on the terminal 10 by registering the location information of the terminal 10 based on the identification information associated with the cell 1 included in the initial terminal message.

The location information registration unit 320 confirms the type of handover confirmed by the handover type checking unit 310 with respect to the terminal 10 in which the location information is registered.

In this case, the location information registration unit 320 registers the location information of the cell (cell 1 -> cell 2) received from the target cell, that is, the first base station 100 of the cell 2, 2, the terminal 10 can perform the location information registration procedure.

In other words, the location information registration unit 320 registers the location information received from the target cell, that is, the first base station 100 of the cell 2, only when the type of the confirmed handover is a base domestic handover (for example, (E.g., ECGI) related to the cell 2 and updates the location information of the terminal based on the identification information (e.g., ECGI) related to the cell 2 in the location information report message.

On the other hand, if the type of handover confirmed is an inter-base station handover (e.g., cell 1? Cell 3), the location information registration unit 320 registers the location of the target cell That is, based on the identification information associated with the cell 3, the terminal 10 can perform the location information registration procedure.

At this time, the information generated in the handover process is transmitted to the UE 10 so as to change the downlink data transmission path from the source cell, i.e., the first base station 100 of the cell 1 to the second base station 200 of the target cell, It is desirable to be a requesting route change request.

In other words, if the type of handover confirmed is inter-base station handover (for example, cell 1 - > cell 3), the location information registration unit 320 registers the target cell, i.e., cell 3 does not receive the location information report message from the second base station 200 of FIG.

Meanwhile, as described above, in the case where the UE 10 performs inter-base station handover (for example, cell 1 - > cell 3) as an inter-cell handover, The second base station 200 of the cell 3 provides a separate message to the network device 300.

For example, when the handover complete message is received from the terminal 10 performing inter-base station handover (e.g., cell 1 -> cell 3), the second base station 200 of the cell 3 transmits a downlink To the network device 300, a path change request message requesting to change the link data transmission path from the source cell, i.e., the first base station 100 of cell 1 to the second base station 200 of the target cell, cell 3. At this time, the path change request message includes identification information (e.g., ECGI) related to the cell 3.

In this case, the location information registration unit 320 registers the information generated in the handover process of the terminal 10, that is, the cell 3, which is the target cell, in the case where the kind of the handover confirmed is the handover between the base stations From the route change request message provided from the second base station 200 of the base station 200 and updates the location information of the terminal on the basis of the identification information related to the cell 3 to perform the location information registration procedure with respect to the terminal 10 have.

As described above, the location information registration unit 320 registers the location information of the terminal 10 in different manners depending on whether the type of inter-cell handover performed by the terminal 10 is a known domestic handover or an inter- The location information registration process is performed.

Thus, the base station apparatus and the network apparatus according to the present invention can provide the location information reporting message to the network apparatus only when the terminal performs the base station handover (e.g., cell 1 - > cell 2) When the terminal performs handover between the base stations (e.g., cell 1 - > cell 3), the BS acquires the location information of the MS 10 by acquiring the identification information related to the target cell, The network device can acquire the identification information related to the target cell from the route change request message generated in the handover process without providing the message to the network device and perform the location information registration procedure for the terminal.

Therefore, the base station apparatus and the network apparatus according to the present invention update location information of a mobile station without providing an unnecessary location information report message when an inter-cell handover performed by the mobile station is an inter-base station handover, It is possible to reduce the processing load by reducing the unnecessary message throughput of the base station apparatus and the network apparatus by updating the location information of the terminal through the provision of the location information report message only in the case of the base station domestic handover, So that the effect can be efficiently managed.

Hereinafter, an operation method of the base station apparatus and the network apparatus according to the present invention will be described with reference to FIG. 4 and FIG.

First, with reference to FIG. 4, the operation flow of the communication system including the base station apparatus and the network apparatus according to the present invention will be described.

When the terminal 10 is connected to the cell 1 of the first base station 100 and the cell 1 of the cell 2 in step S10, the first base station 100 transmits the initial terminal message including the identification information related to the cell 1 to the network device 300) (S20).

The network device 300 registers location information indicating to which cell the terminal 10 is connected based on the identification information associated with the cell 1 included in the initial terminal message, An information registration procedure can be performed (S30).

In this way, when the terminal 10 is connected to the cell 1 of the first base station 100, the cell of the first base station 100, which is received by the terminal 10 due to the movement of the terminal 10 or the change of the radio environment, 1 and the signal strength of other cells is relatively large, the terminal 10 performs handover from the currently connected cell 1 to another cell. That is, the terminal 10 performs inter-cell handover.

Here, the inter-cell handover in which the UE 10 is handed over from the cell 1, that is, the source cell to another cell, i.e., the target cell, can be divided into a base domestic handover and an inter-base station handover.

First, a case where a terminal 10 is handed over from a cell 1 of a first base station 100 to another cell (for example, a cell 2 of the same first base station 100) In case of over (S40), the first base station 100 can confirm that the type of the handover to the terminal 10 is the base domestic handover.

In this case, the first base station 100 performs a location information reporting procedure for providing the terminal 10 with the identification information related to the target cell (e.g., cell 2) to the network device 300 separately (S44).

In other words, the first base station 100 provides a location information reporting procedure that separately provides the location information report message including the identification information (e.g., ECGI) associated with the target cell (e.g., cell 2) to the network device 300 Can be performed.

The network device 300 determines whether the type of inter-cell handover performed by the terminal 10 is a base station handover (e.g., cell 1 - > cell 2) (E.g., ECGI) related to the cell 2 and updates the location information of the terminal based on the identification information (e.g., ECGI) related to the cell 2 in the location information report message received from the terminal 10 (S46).

The inter-base station handover will be described with reference to an inter-base station handover from a cell 1 of a first base station 100 to a cell of another second base station 100 (e.g., cell 3) (S50), the second base station 100 can confirm that the type of the handover to the terminal 10 is handover between the base stations.

In this case, the second base station 200 does not separately provide the terminal 10 with identification information related to the target cell (e.g., cell 3) to the network device 300, unlike the base domestic handover.

In other words, the second base station 200 does not separately provide the network device 300 with a location information report message including identification information (e.g., ECGI) associated with the target cell (e.g., cell 3).

The second base station 200 may transmit the downlink data to the terminal 10 when the handover complete message is received from the terminal 10 performing inter-base station handover (e.g., cell 1 -> cell 3) To the network device 300, a route change request message requesting to change the path from the source cell, i.e., the first base station 100 of the cell 1 to the second base station 200 of the target cell, that is, the cell 3 (S52).

The network device 300 determines whether the handover of the inter-base station handover performed by the terminal 10 is an inter-base-station handover (e.g., cell 1 -> cell 3) (Step S54), and updates the location information of the terminal based on the identification information associated with the cell 3 from the route change request message provided from the second base station 200 of the cell 3 serving as the target cell The location information registration procedure may be performed (S56).

Hereinafter, an operation method of the base station apparatus according to the preferred embodiment of the present invention will be described in detail with reference to FIG.

The method of operation of the base station apparatus according to the present invention checks the type of handover for a terminal handed over from a source cell to a target cell (S100).

That is, the method of operation of the base station apparatus according to the present invention can confirm the type of handover to the terminal 10 when the terminal 10 to be handed over is determined as a target cell of the base station 100.

For example, when the terminal 10 is handed over from a cell 1 of a source cell, such as the base station 100, to another cell 2 of a target cell, for example, the base station 100, The type of the handover to the base station 10 will be confirmed as a base domestic handover.

Meanwhile, if the terminal 10 is handed over from the cell 3 of the source cell, for example, the second base station 200, to the cell 2 of the target cell, for example, the base station 100, The type of the handover to the terminal 10 by inter-base station handover.

The method of operating the base station apparatus according to the present invention performs the location information reporting procedure related to the target cell differently to the terminal 10 according to the type of handover identified in step S100.

More specifically, the method of operation of the base station apparatus according to the present invention is characterized in that the identification information associated with the target cell is separately transmitted to the network device (10) only when the type of handover identified in step S100 is a base domestic handover 300 in step S120.

For example, the method of operation of the base station apparatus according to the present invention may be performed only when the type of handover identified in step S100 is a base domestic handover (for example, cell 1 - > cell 2) It is possible to perform a location information reporting procedure that separately provides the location information report message including the related identification information (e.g., ECGI) to the network device 300. [

The network device 300 confirms identification information (e.g., ECGI) related to the target cell (e.g., cell 2) to which the terminal 10 has been handed over in the location information report message received separately from the base station device 100 And updates the location information of the terminal on the basis of the location information.

Meanwhile, in the operation method of the base station apparatus according to the present invention, when the kind of the handover confirmed in step S100 is inter-base station handover (for example, cell 3 -> cell 2) It is not provided to the device 300.

More specifically, in the case where the terminal 10 performs inter-base station handover as inter-cell handover (for example, cell 3 -> cell 2) as described above, 2, the method of operation of the base station apparatus according to the present invention provides a separate message to the network device 300.

For example, when the handover complete message is received from the terminal 10 performing the inter-base station handover (e.g., cell 3 - > cell 2) To the network device 300, a path change request message requesting to change the downlink data transmission path for the cell 2 from the source cell, i.e., the second base station 200 of the cell 3 to the target cell, that is, the base station device 100 of the cell 2 (S115).

Therefore, when the type of handover identified in step S100 is inter-base station handover (for example, cell 3 - > cell 2), the method of operating the base station apparatus according to the present invention further includes transmitting the location information report message to the network device 300 Instead, the network device 300 can perform the location information registration procedure for the terminal 10 using the route change request message generated in the handover process for the terminal 10, instead.

When the terminal 10 performs inter-base-station handover (for example, cell 3 - > cell 2), the network device 300 transmits a path change request message received during the handover process to the target cell The location information registration procedure for the terminal 10 can be performed based on the obtained identification information.

Hereinafter, a method of operating a network device according to a preferred embodiment of the present invention will be described in detail with reference to FIG.

A method of operating a network device according to the present invention is a method of operating a network device according to a first embodiment of the present invention with respect to a terminal 10 handed over from a cell 1 of a source cell such as a first base station 100 to a target cell (S200).

That is, in the method of operating the network device according to the present invention, when the terminal to which the inter-cell handover is performed, that is, the terminal 10, among the terminals where the location information is previously registered in the network device 300, It is checked whether the type of the handover is a base domestic handover or an inter-base-station handover.

In this case, when the location information report message is received from the base station of the target cell to the terminal 10 that has performed the inter-cell handover, If the path change request message is received from the base station of the target cell with respect to the base station 10, it can be confirmed that the handover is performed between the base stations.

The method of operating the network device according to the present invention performs the location information registration procedure related to the target cell differently for the terminal 10 according to the type of the handover identified in step S200.

More specifically, the method of operation of the network device according to the present invention is characterized in that when the type of handover identified in step S200 is a base domestic handover (for example, cell 1 - > cell 2) The terminal 10 can perform the location information registration procedure based on the identification information related to the cell 2 received separately from the first base station 100. [

In other words, the operating method of the network device according to the present invention is characterized in that when the type of handover confirmed in step S200 is a base domestic handover (for example, cell 1 - > cell 2) (E.g., ECGI) related to the cell 2 in the received location information report message and updates the location information of the terminal based on the received location information report message, The location information registration procedure may be performed for the mobile terminal 10 (S230).

Meanwhile, the method of operating a network device according to the present invention is a method of operating a network device in a case where the type of handover identified in step S200 is an inter-base station handover (e.g., cell 1? Cell 3) The terminal 10 can perform the location information registration procedure based on the identification information associated with the target cell, i.e., the cell 3, identified from the information.

In other words, the operation method of the network device according to the present invention is characterized in that when the type of handover confirmed in step S200 is inter-base station handover (for example, cell 1 - > cell 3) The second base station 200 of the cell 3 does not receive the location information report message.

Meanwhile, as described above, in the case where the UE 10 performs inter-base station handover (for example, cell 1 - > cell 3) as an inter-cell handover, The second base station 200 of the cell 3 provides a separate message to the network device 300.

For example, when the handover complete message is received from the terminal 10 performing inter-base station handover (e.g., cell 1 -> cell 3), the second base station 200 of the cell 3 transmits a downlink To the network device 300, a path change request message requesting to change the link data transmission path from the source cell, i.e., the first base station 100 of cell 1 to the second base station 200 of the target cell, cell 3.

Accordingly, the method of operating the network device according to the present invention is characterized in that when the type of handover confirmed in step S200 is an inter-base station handover (e.g., cell 1 - > cell 3) Information on the cell 3 from the path change request message provided from the second base station 200 of the cell 3 serving as the target cell and updates the location information of the terminal based on the identification information, A registration procedure can be performed (S240).
