BACKGROUND OF THE INVENTION Traditional macro base station (macro eNB) single layer overlay networks have been unable to meet the growing demand for data traffic rates and capacity. Therefore, a layered networking method is introduced to solve the problem by deploying some low-power base stations in a small coverage environment such as a hotspot area, a home indoor environment, and an office environment (hereinafter referred to as a local eNB, that is, a local base station, including Femto). /Pico/Relay and other forms), the effect of cell splitting, enabling operators to provide users with higher data rates and lower cost services.

In order to reduce the frequency of handover between the macro cell and the local cell, a network deployment mode in which the user plane and the control plane are separated is introduced, that is, data bearer and signaling control of the same user. They are provided by different base stations. As shown in Figure 4, the macro cell provides basic coverage, the local cell provides hotspot coverage, and the data/signaling interface (wired/wireless interface) exists between the local cell and the macro cell. The UE can work under the macro eNB or local eNB.

The embodiment of the present invention provides a scenario in which Heterogeneous Network (HetNet), which is composed of cells of different sizes and types, including: macro cell, local cell, A wireless communication system manages a local (local) community common resource solution.

In order to implement the local cell common resource management in the bearer separation network, the embodiment of the present invention provides the following solutions: The common resource of the local cell is managed and configured by the macro eNB, whenever the local cell is public. When the resource changes, the macro eNB notifies all the UEs that are separated from the local cell (that is, the data bearer provided by the local eNB and the signaling bearer provided by the macro eNB) to perform common resource configuration.

FIG. 2 is a flowchart of a local cell common resource configuration after a local eNB is started according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps.

Step 1: After the local eNB starts, the local eNB initiates an establishment process of the M-L interface, in which the local eNB sends an M-L setup request to the macro eNB (M-L Setup

Request ) The message contains a list of local cells requesting the allocation of common resources.

In the local cell list, corresponding to each local cell includes: a local cell identifier (for uniquely identifying a logical cell on the _locca eNB). In an embodiment, the local cell list may further include hardware capabilities (such as power capability, other hardware features, and the like) that may be supported by the local cell, and/or carrier type configuration information (indicating that the corresponding local cell can work independently or cannot work independently). ).

Step 2: After receiving the M-L setup request message, the macro eNB configures a common resource for each local cell in the local cell list, and then sends an M-L Setup Response message to the local eNB. The M-L setup response message includes a list of local cells and common resource information configured for each local cell.

In the local cell list, each local cell includes identification information of a local cell, such as a local cell identifier, or/and, ECGI (evolved cell global ID, an evolved cell global identifier, that is, a unique identifier of a logical cell) . The first 20 bits of ECGI are the eNB ID of the macro eNB. Corresponding to each local cell, the public resource information of the local cell is further included, and the common resource information may include one or any combination of the following information:

Information such as PLMN (Public Land Mobile Network) or / and TAC (Tracking Area Code);

PCI (Physical Cell Identifier), frequency, bandwidth, etc.; RACH (Random Access Channel) or PRACH (Physical

Random Access Channel, physical random access channel) public configuration information;

PDSCH (Physical Downlink Shared Channel) public configuration information;

PUSCH (Physical Uplink Shared Channel) public configuration information;

PHICH (Physical Hybrid ARQ Indicator Channel, Physical HARQ (Hybrid Automatic Repeat Request) indication channel) Set information

SoundingRS (RS (Reference Signal) for channel measurement, also known as SRS) common configuration information;

Antenna configuration information;

P-Max (maximum transmit power);

TDD (Time Division Duplexing) physical channel configuration information; information such as uplink cyclic prefix length.

In an embodiment, for the local cell that can work independently, the common resource information may further include a BCCH (Broadcast Control Channel) configuration information, or/and a PCCH (Physical Control Channel) configuration information. . Here, the local cell that can work independently refers to: a cell that can reside in the idle UE and can access.

In an embodiment, the local cell list in the ML establishment response message may include carrier type configuration information (indicating corresponding to the local cell identification information and the allocated common resource information). The local cell can work independently or not independently.

After receiving the M-L setup response message, the local eNB starts to configure these common resources. The local eNB establishes and sends a system message (such as cell-specific signaling) according to the configuration information carried in the ML establishment response message, and the UE in the corresponding local cell receives the system message. Configure or reconfigure local community common resources based on the configuration information carried in it.

In an embodiment, in the process shown in FIG. 2, after the macro eNB allocates a common resource for the local cell, for the local cell that cannot work independently, the macro eNB uses the dedicated signaling (such as UE-specific signaling) to the local cell. The public resource information is sent to the UE that is separated to the local cell, so that the UE performs local cell common resource configuration.

In one embodiment, the common resources of the local cell may be configured in advance in an OAM (Operation Administration and Maintenance) server. In the process shown in FIG. 2, after the macro eNB receives the M-L setup request message sent by the local eNB in step 2, the public resource configuration of the corresponding local cell may be obtained from the OAM server, and then sent to the local eNB.

When the macro eNB decides to modify the configured common resources, FIG. 3 is a flowchart of the macro eNB updating the local d and the regional common resource configuration in the embodiment of the present invention. As shown in Figure 3, the method can include the following steps.

Step 1: The macro eNB sends a macro configuration update message to the local eNB, and the message includes one or any combination of the following information:

The added cell information group; The cell information group to be deleted;

The cell information group that needs to be modified.

The newly added cell information group includes a local cell list to be established, and each l _oca l cell corresponding to each of the _locca cells contains the identification information and common resource information of the corresponding local cell. The public resource information may be one or any combination of the information listed in step 2 of the flow shown in FIG. 2.

The cell information group to be modified includes a list of local cells to be modified, and each local cell corresponding to the local cell contains identification information of the corresponding local cell, such as ECGI, and updated public resource information. These common resource information may be any one or any combination of the information listed in step 2 of the flow shown in FIG. 2.

If the macro eNB decides to delete a local cell, all the UEs connected to the local cell are merged into the macro eNB in advance (that is, the user plane bearer of the UE is transferred back to the macro eNB, that is, the UE is provided by the macro eNB. The data carries), and then sends the cell information group to be deleted to the local eNB. The information group contains the list of local cells to be deleted, including the identification information of each local cell, such as ECGI. For example, if there are two UEs on a local cell (in the case where the control plane and the user plane are separated, the user plane may remain on the local eNB, and the control plane remains on the macro eNB;), so that when the macro eNB deletes In the local cell, the user planes of the two UEs are first transferred back to the macro eNB, that is, the two UEs are merged into the macro eNB.

Step 2: The local eNB reconfigures the common resources of the corresponding local cell according to the content in the macro configuration update message, and organizes and sends a macro configuration update confirmation message to the macro eNB. For a local cell that can work independently, the local eNB organizes and sends a system message according to the content of the macro configuration update message, to indicate that the UE in the corresponding local cell performs public resource configuration.

Step 3: After the macro eNB receives the macro configuration update confirmation message, the macro uses the proprietary signaling manner to notify the UE that is separated to the local to perform _{publicization} for the non-operating l _oca l cell. Resource configuration.

In an embodiment, in the foregoing process shown in FIG. 3, before the macro eNB sends the macro configuration update message to the local eNB (that is, before step 1), the method may further include the following steps: the macro eNB interacts with the OAM server to obtain a corresponding The public cell information of the local cell is modified, or the local cell is deleted through the interaction process, or the local cell needs to be added through the interaction process. Correspondingly, in step 1, the macro eNB sends a macro configuration update message to the local eNB according to the interaction with the OAM server, where the corresponding cell information group is carried.

If the physical hardware of the local eNB changes or other events that may affect the configuration of the common resource of the local cell occur, the macro eNB needs to be notified. FIG. 4 is a flowchart of a local eNB requesting to update a local resource common resource configuration according to an embodiment of the present invention. As shown in Figure 4 The process can include the following steps.

Step 1: The local eNB sends a local config update request message to the macro eNB, where the message includes one or any combination of the following: the added cell information group;

The cell information group to be deleted;

The cell information group that needs to be modified.

The newly added cell information group includes a list of local cells to be established, and each l _oca l cell includes identification information of the corresponding local cell (such as a local cell identifier), and may also include that the local cell may support Hardware capabilities. In one embodiment, carrier type configuration information may also be included.

In an embodiment, hardware capabilities that may be supported by the local cell, and/or carrier type configuration information may also be included.

The cell information group to be deleted includes the local cell list to be deleted, and each local cell corresponding to the local cell contains the identification information of the corresponding local cell.

Step 2: After receiving the local configuration update request message, the macro eNB performs common resource configuration or processing on the corresponding local cell according to the content of the message, and organizes and sends a local configuration update confirmation message to the local eNB.

Specifically, if the local configuration update request message carries an increased cell information group, the macro eNB configures a common resource for the newly added local cell according to the cell information group, and carries the configured common resource information to the local configuration update. A confirmation message is sent to the local eNB. If the local configuration update request message carries the cell information group to be modified, the macro eNB reconfigures the common resource for the local cell that needs to modify the common resource according to the cell information group, and carries the configured common resource information to the local configuration update. A confirmation message is sent to the local eNB. If the local configuration update request message carries the cell information group to be deleted, the macro eNB deletes the common resource information of the corresponding local cell according to the cell information group, and returns a local configuration update confirmation message to the local eNB.

For the content of the local configuration update confirmation message, refer to the macro configuration update message sent by the macro eNB in step 1 of the process shown in FIG.

After receiving the local configuration update confirmation message, the local eNB performs corresponding configuration processing. The local eNB organizes and sends a system message according to the content of the macro configuration update message to indicate that the UE in the corresponding local cell performs common resource configuration.

In an embodiment, after the macro eNB allocates the common resource to the local cell, the macro eNB sends the public resource information of the local cell to the UE that is separated by the local cell by using dedicated signaling. So that the UE performs local cell common resource configuration.

In an embodiment, in the process shown in Figure 4 above, the macro eNB receives the local After the update request message is configured, the following steps may be further included: The macro eNB obtains the common resource information of the corresponding local cell from the OAM server. Correspondingly, in step 2, the macro eNB sends a macro configuration update message to the local eNB according to the obtained common resource information of the corresponding local cell.
