Description

[0001] FEMTOCELL APPARATUS AND METHOD FOR SETTING THE SAME [0002]

The present invention relates to the field of communications. More particularly, the present invention relates to a femtocell device and a setting method for providing a mobile communication service, setting a PCI, and the like.

The coverage of the base station is gradually decreasing according to the trend of the mobile communication market requiring high-speed data. To meet this trend, a femtocell technique for providing services to a limited area such as a home or an office with a much narrower range than a conventional mobile communication base station having a service range of 0.5 to 5 km has been proposed.

The femtocell technology is a technology for providing wired / wireless communication to a mobile communication device such as a cellular phone by connecting an existing wired terminal such as a telephone or a computer, which is installed in the home, office, or the like, to the Internet.

The femtocell transmits the data from the base station to the exchange directly without going through the indoor repeater, thereby reducing the construction cost of the communication network and improving the quality of the call.

Network operators will need more base stations for good data services in the same area and it will be costly to install and maintain multiple base stations. That is, a large number of people and time are required to determine wired / wireless related parameters. Since it is not easy to find optimal conditions for the variable location of the base station and the changing radio environment, the base station and the network are installed automatically, and a SON (Self Organizing Network) that adapts to the changing radio environment and data traffic environment is required .

PCI (Physical Cell Identity) is the most basic parameter set in the base station. The base station performs random sequence generation, synchronization signal generation, and subcarrier mapping of a downlink reference signal using PCI.

According to a conventional method of setting PCI and NCL, a wireless network operator configures each PCI according to which cell is formed around a base station and constructs a neighbor cell list (NCL) NCL was configured by manual installation rather than automatic installation. However, as more base stations are needed to provide quality service, it becomes difficult to manually set PCI and NCL each time a base station is installed.

A femtocell device and a method of setting a femtocell device according to an embodiment of the present invention aim at minimizing a function of a HeMS (Home eNode B Management System) server for managing a femtocell.

Hereinafter, exemplary embodiments according to the technical idea of the present invention will be described with reference to the drawings.

1 is an exemplary diagram illustrating an environment in which a femtocell device 100 according to an embodiment of the present invention is applied.

The femtocell device 100 is installed to provide a mobile communication service to the terminal 10a in a small area such as a home or an office. The femtocell apparatus 100 is connected to the home network 20 (e.g., an ONT) and connected to an Internet network 30 such as a wide area network (WAN) And is connected to the communication network 40.

The base station 50 provides a mobile communication service to the terminal 10b in the coverage as in the femtocell device 100 but differs from the femtocell device 100 in that the base station 50 is directly connected to the mobile communication network 40. [

The Internet network 30 and the mobile communication network 40 are connected to each other through the femtocell gateway 31. The femtocell device 100 can establish an IPsec tunnel with the femtocell gateway 31. [

The femtocell device 100 can set parameters under the management of the Home eNode B Management System (HeMS) server 41 of the mobile communication network 40. [ For example, conventionally, when the femtocell device 100 is booted, related information can be received from the HeMS server 41 and parameters for the mobile communication service can be set.

As one of the parameters, the femtocell device 100 sets PCI, which is a unique identifier. At this time, the femtocell device 100 identifies the PCIs set in the neighbor femtocell device through sniffing, And PCI are selected and set. However, when the PCI is set through the sniffing scheme, there is a problem that the PCI of the adjacent femtocell device can be set to overlap with the PCI.

2 is a diagram for comparing the sniffing coverage 210 and the mobile communication coverage 230 of the femtocell device 100 according to an embodiment of the present invention.

As shown in FIG. 2, it can be seen that the sniffing coverage 210 is small compared to the mobile communication coverage 230. This requires separate hardware for sniffing, but its performance is limited by hardware performance and sniffing behavior. That is, since the sniffing coverage 210 is smaller than the mobile communication coverage 230, even if the PCI is set through the sniffing process, the PCI may be redundantly set in the adjacent femtocell device in the mobile communication coverage 230 .

In an embodiment of the present invention, not only the sniffing method but also a wireless communication device having a communication radius wider than the sniffing coverage is connected to the femtocell device 100 and the PCI is set in consideration of the peripheral femtocell PCI acquired through the wireless communication method The problem that the PCI is set to be duplicated can be solved.

Meanwhile, in the case of the femtocell device 100, since the mobile communication service is provided through the wired Internet network 30 in a state where the femtocell device 100 is connected to the in-house device 20, when the mobile communication provider and the wired network provider are different from each other, Lt; / RTI > For example, when the mobile communication service is provided by the A provider, the B provider provides the wired Internet service, and the fee-related consultation between the A provider and the B provider is not made, the user transmits the femtocell device 100 to the B provider The femtocell device 100 can not provide the mobile communication service to the terminal 10a even if it is connected to the in-house device 20. [

3 is a flowchart illustrating a femtocell setup method according to an embodiment of the present invention.

In step S310, the femtocell device 100 receives the policy from the HeMS server 41. [ The policy may include an IP address list or a DNS server information list in which the mobile communication service is allowed to be provided. In addition, the policy may further include a PCI list that the femtocell device 100 can select.

In step S320, the femtocell device 100 acquires information on the premises equipment 20 to which the femtocell device 100 is connected. The information of the premise equipment 20 may include at least one of the IP address of the premises equipment 20 and the DNS server information mapped to the premises equipment 20, for example. The DNS server information mapped to the in-premises equipment 20 may include an IP address of a server connected to the in-house equipment 20 and accessed by a computer or the like using the Internet to inquire about the domain name.

In step S330, the femtocell device 100 determines whether to block the mobile communication service by comparing the policy received from the HeMS server 41 with the in-home device 20 information. For example, if the information of the premises equipment 20 is not included in the reception policy, the mobile communication service can be determined to be blocked.

Specifically, when the IP address of the home-use apparatus 20 is not included in the policy IP address list or the DNS server information mapped to the home-use apparatus 20 is not included in the in-policy DNS server information list, It may decide to block the service.

If it is impossible to provide the mobile communication service in step S340, the femtocell device 100 does not provide the mobile communication service to the terminal 10a by blocking the provision of the mobile communication service. When the IPsec tunnel is established between the femtocell device 100 and the femtocell gateway 31, the IPsec tunnel is released to reduce the load on the femtocell gateway 31. [

In step S350, if the mobile communication service can be provided, the femtocell device 100 sets the PCI.

If the provider providing the home-use equipment 20 is different from the mobile communication provider through comparison of the information of the home-use equipment 20 and the policy, the femtocell device 100 ) May output an alarm to invite the user to use the wired network of the same carrier as the mobile communication carrier. A list of IP addresses in the policy or a list of DNS server information may be included in the policy by business operator.

Hereinafter, a method of setting PCI will be described in detail with reference to FIGS. 4 and 5. FIG. In the above description, the PCI is set up when the mobile communication service of the femtocell device 100 is possible. However, according to the implementation example, the femtocell device 100 may transmit the PCI, regardless of whether or not the mobile communication service can be provided, Alternatively, steps S320 to S330 of FIG. 3 may be omitted and the PCI may be set immediately upon booting.

FIG. 4 is a flowchart for explaining step S350 of FIG. 3 in detail.

In step S410, the femtocell device 100 acquires at least one first PCI information set in the neighboring femtocell device through sniffing. The femtocell device 100 may measure the received field strength of the neighboring femtocell device when acquiring at least one first PCI information. Since the received field strength of the neighboring femtocell device that is far from the femtocell device 100 is smaller than the received field strength of the neighboring femtocell device located relatively close to the neighboring femtocell device 100, the distance to the neighboring femtocell device can be calculated through the measured received field strength Do. In addition, the femtocell device 100 may further acquire the cell ID and frequency information (e.g., EARFCN) of the neighbor femtocell device through sniffing.

In step S420, the femtocell device 100 receives at least one second PCI information set in the neighbor femtocell device from the wireless communication device connected to the femtocell device 100. [ The wireless communication coverage of the wireless communication device is wider than the sniffing coverage and the wireless communication device may communicate with the peripheral wireless communication device connected to the peripheral femtocell device and receive the at least one second PCI information. A wireless communication device may include, but is not limited to, a WiFi device, for example.

Since the wireless communication coverage is wider than the sniffing coverage, the second PCI information may include the first PCI information and the PCI information of the neighboring femtocell located at a place where the sniffing coverage does not reach.

The wireless communication device may also measure the received field strength of the peripheral wireless communication device when acquiring at least one second PCI information. Since the received field strength of a peripheral wireless communication device that is a long distance away from the wireless communication device is smaller than the field strength of a peripheral wireless communication device that is located relatively close to the peripheral wireless communication device, It is possible.

However, since there is a difference between the transmission / reception field strength of the mobile communication system of the femtocell device 100 and the transmission / reception field strength of the wireless communication system of the radio communication apparatus, To be transmitted to the femtocell device 100. The femtocell device 100 of FIG. If the femtocell device 100 transmits the received electric field strength of the wireless communication method itself to the femtocell device 100, the femtocell device 100 can not know how far the neighboring wireless communication devices or peripheral femtocell devices connected thereto are spaced apart from the femtocell device 100 to be. For example, when the received electric field strength of any one of the peripheral wireless communication apparatuses is -70 dBm, the wireless communication apparatus changes the received electric field intensity to -110 dBm, which is the received electric field strength of the mobile communication system, and transmits the signal to the femtocell apparatus 100.

In some implementations, the femtocell device 100 may receive the received field strength information according to the wireless communication scheme from the wireless communication device, and then convert it into the received field strength of the direct mobile communication scheme.

The femtocell device 100 can know how far each of the at least one second PCI information has been set in the surrounding femtocell equipment from its own according to the received field strength information received from the wireless communication device.

In addition, the wireless communication device may further acquire the cell ID and frequency information (e.g., EARFCN) of the neighboring femtocell device through the wireless communication and deliver it to the femtocell device 100. [

In step S430, the femtocell device 100 determines whether there is a settable PCI list in the PCI list received from the HeMS server 41. [ Specifically, the femtocell device 100 may determine whether there is a remaining PCI by excluding the first PCI information and the second PCI information among the PCIs included in the PCI list. Specifically, the femtocell device 100 receives the cell ID, the frequency information, and the first PCI information of the peripheral femtocell device acquired through the sniffing, the cell ID and the frequency information of the peripheral femtocell device acquired by the wireless communication device, It is possible to determine whether or not there is a configurable PCI by referring to the information. It is possible to exclude the PCIs set in the peripheral femtocell device using the same frequency as that of the self-used femtocell device from the PCI list and to select the remaining PCI as the configurable PCI. In addition, since the first PCI information and the second PCI information set in the femtocell device having the same cell ID among the information acquired through the sniffing and the information acquired by the wireless communication device are redundant information, You can choose.

If a configurable PCI remains, the femtocell device 100 sets the remaining PCI to its own PCI in step S440.

If there is no settable PCI, the femtocell device 100 sets the same PCI as the PCI set in the peripheral femtocell having the lowest received electric field intensity according to the mobile communication scheme to its own PCI in step S450. For example, the femtocell device 100 may use the same frequency as the frequency used by the femtocell device 100 and set the same PCI as the PCI set in the peripheral femtocell with the lowest received electric field intensity as its own PCI. That is, the PCI set to the neighbor femtocell farthest from itself is set as its own PCI. The neighbor femtocell far away from itself is not likely to have a communication collision due to its wide area overlapping with its own communication coverage.

After the PCI is set in the femtocell device 100, the femtocell device 100 may transmit the set PCI information to the wireless communication device so that the wireless communication device transmits the PCI information to the peripheral wireless communication device. After the PCI is established, the femtocell device 100 may transmit not only the set PCI but also its own cell ID and frequency information used by the femtocell device 100 to the wireless device so that the wireless communication device can transmit it to the outside.

FIG. 5 is a flowchart illustrating a process after PCI is set up in FIG.

After the PCI is set in the femtocell device 100, the femtocell device 100 acquires the third PCI information set in the neighboring femtocell device from the wireless communication device in step S510. As described above, when acquiring the third PCI information, the wireless communication device measures a received electric field intensity of the peripheral wireless communication device, converts the received electric field intensity into a received electric field intensity of the mobile communication method, and provides the received electric field intensity to the femtocell device 100 . In addition, the wireless communication device may further acquire the cell ID and frequency information (e.g., EARFCN) of the neighboring femtocell device through the wireless communication and deliver it to the femtocell device 100. [

In step S520, the femtocell device 100 determines whether the same PCI as the PCI set in the femtocell device 100 is set in the neighboring femtocell device. For example, the femtocell device 100 can determine whether the neighboring femtocell device using the same frequency as the user has set the same PCI as its own.

If the same PCI as the PCI set in itself is not set in the neighbor femtocell device, the femtocell device 100 maintains the PCI set in itself in step S530.

However, if the same PCI as the PCI set in itself is set in the neighbor femtocell device, the femtocell device 100 compares the PCI setup time or the priority of the femtocell device in step S540. For example, it is possible to compare the time when the PCI is set to the neighboring femtocell device with the time when the neighboring femtocell device is set to the same PCI, or compare the priorities of neighboring femtocell devices having the same PCI and the same priority. The priority of each femtocell device may be transmitted from the HeMS server 41 to the femtocell device 100 at boot time.

If the time at which the femtocell device 100 sets the PCI is earlier than the time at which the neighboring femtocell device sets the same PCI or the priority of the peripheral femtocell device is higher than the priority of the neighboring femtocell device, Gt; PCI < / RTI >

However, if the time at which the femtocell device 100 has set the PCI is later than the time at which the neighboring femtocell device has set the same PCI, or if its priority is lower than the priority of the peripheral femtocell device, , And resets its own PCI. Specifically, if there is a remaining PCI except for the third PCI information among the PCIs included in the PCI list, the femtocell device 100 resets to the corresponding PCI, and if there is no remaining PCI except for the third PCI information , It sets the same PCI as the PCI of the peripheral femtocell device having the lowest received electric field strength as its own PCI as described above.

4, the PCI of the femtocell device 100 is set in consideration of the first PCI information acquired through the sniffing and the second PCI information acquired through the wireless communication method. However, according to the embodiment, It is possible to set the PCI of the femtocell device 100 considering only the first PCI information acquired through the first PCI information and to maintain the predefined PCI in consideration of the third PCI information of FIG.

6, the femtocell device 100 according to another embodiment of the present invention may include a first communication unit 110, a second communication unit 130, a control unit 150, and a memory 170. FIG. The first communication unit 110, the second communication unit 130, the control unit 150 and the memory 170 may be implemented by at least one processor and may operate according to a program stored in the memory 170.

The first communication unit 110 performs communication using a mobile communication method. The first communication unit 110 communicates with the terminal 10a in coverage and provides a mobile communication service or sniffs the neighboring femtocell device according to the mobile communication scheme. The first communication unit 110 may collect information of the premises equipment 20 connected to the femtocell apparatus 100 and may receive the policy from the HeMS server 41. [

The second communication unit 130 communicates with the wireless communication device 600 and receives the information of the neighboring femtocell device from the wireless communication device 600. The information of the neighboring femtocell device may include, for example, PCI information set in the neighboring femtocell device and received field strength information of each neighboring femtocell. 6 illustrates that the femtocell device 100 and the wireless communication device 600 are separated from each other. However, the wireless communication device 600 may be embedded in the femtocell device 100 according to an embodiment.

The control unit 150 compares the PCI list stored in the memory 170 with the first PCI information acquired by the first communication unit 110 and the second PCI information acquired by the second communication unit 130 and transmits the PCI information to the femtocell device 100. [ Of PCI. The control unit 150 compares the information of the premises equipment 20 collected through the first communication unit 110 with the policy stored in the memory 170 to determine whether or not the mobile communication service is provided. If it is determined that the mobile communication service can not be provided, the controller 150 can release the IPsec tunnel established between the first communication unit 110 and the femtocell gateway 31.

The memory 170 may store a policy received from the HeMS server 41, a priority list for each femtocell device, and the like.

Meanwhile, the embodiments of the present invention described above can be written in a program that can be executed in a computer, and the created program can be stored in a medium.
