Background technique

In the upgraded Long Term Evolution-Advanced (LTE-A) system, a Relay Node (RN) is introduced to increase system throughput and increase network coverage. The RN is connected to the donor base station (Don Evolved Node B, DeNB) in a wireless manner. The interface between the user terminal (UE) and the RN is called the Uu port, and the interface for transmitting data between the RN and the DeNB is called the Un port. Referring to FIG. 1, the RN is indirectly connected to other base stations (e B ) through its own DeNB. And the cell under the RN may be adjacent to the cell under other base stations. The base station connected to the RN is called a DeNB, and the DeNB is a type of an eNB.

In the Long Term Evolution (LTE) network, for the purpose of load balancing, certain resource reporting and reporting processes need to be performed between eNBs. The purpose is to grasp the load situation of the neighboring cell, adjust the parameters such as handover and cell reselection, so that the network can load balance, improve transmission efficiency and overall network performance.

detailed description

Referring to Fig. 1, the communication system in this embodiment includes a first base station 101, a second base station 102, and a relay device 103. The first base station 101 has an X2 interface with the relay device 103, and thus the first base station 101 is a DeNB. The second base station 102 and the first base station 101 have an X2 interface, but there is no direct interface with the relay device 103, and there may be an interface with other relay devices, or may not exist with any relay device. interface.

The second base station 102 is configured to send a resource status report request, and in particular, send a resource status report request to the first base station 101 through the X2 interface. The resource status report request may use the structure of the existing resource status report request signaling (RESOURCE STATUS REQUEST), where the identifier of the target cell (also a neighboring cell) (such as a cell ID (cell ID), etc.) is carried, and the target cell For a cell that needs to report resource status information, the target cell here may be a cell under the relay device 103. The second base station 102 further receives, by using the X2 interface, resource status update signaling that is returned by the first base station 101 and carries resource status information about the Uu port and the Un port of the relay device 103. The resource status update signaling can also use the structure of the existing resource status update signaling (RESOURCE STATUS Update). The second base station 102 can carry the reporting period in the resource status reporting request, so that the first base station 101 and the relay device 103 periodically report the resource status information.

The first base station 101 is configured to forward the resource status report request sent by the second base station 102 to the relay device 103; receive the resource status information sent by the relay device 103; and carry the Uu port and the Un port of the relay device 103. The resource status update signaling of the resource status information is sent to the second base station 102. The first base station 101 receives the resource status of the second base station 102 through the X2 interface, where the resource status carries the identifier of the cell, and the first base station 101 stores the identifier of the cell and the identifier of the relay device 103. Corresponding relationship, the relay device 103 corresponding to the identifier of the cell may be determined. The first base station 101 sends the related domain in the received resource status report request to the relay device 103, and in particular updates the content of the relevant domain of the X2 interface signaling proxy function, and the updated content is as follows: The content such as the ID assigned between the first base station 101 and the first base station 101 is replaced with an ID or the like assigned between the first base station 101 and the relay device 103, such as a base station measurement identifier (e B Measurement ID). The first base station 101 transmits the updated resource status report request to the relay device 103.

Since the first base station 101 can directly obtain the resource status information about the Un port of the relay device 103 by using the measurement, the relay device 103 can directly obtain the resource status information of the Uu interface by the measurement, and the first base station 101 wants to obtain the related relay device. There are various specific implementations of the resource status information of the Uu port and the Un port of 103.

As the first type: The first base station 101 receives the resource status information about the Uu port sent by the relay device 103. Specifically, the first base station 101 receives the resource status update signaling that carries the resource status information of the Uu interface through the X2 interface, and parses the Extract the resource status information of the Uu port. The first base station 101 may carry the resource status information of the Uu interface and the resource status information about the Un interface of the relay device 103 that are obtained locally in the resource status update signaling, and report the foregoing to the second base station 102. Alternatively, the first base station 101 compares the resource status information of the received Uu interface with the resource status information of the Un port of the relay device 103 that is obtained locally, and determines resource status information about the Uu port and the Un port of the relay device. The resource state information that has the greatest impact on the load balancing is forwarded to the second base station 102 by the resource state update signaling that carries the determined resource state information that has the greatest impact on the load balancing. In this way, the second base station 102 can grasp the load condition of the target cell, save network resources, and can use the existing signaling format. Similar to the receiving process, the first base station 101 needs to update the content of the relevant domain of the signaling proxy function in the resource state update signaling according to the second base station 102, and send the updated resource state update signaling to the second base station 102.

The resource status information that has the greatest impact on the load balancing in the resource status information of the Uu port and the Un port of the relay device 103 includes at least one or any combination of the following: a hardware load of the Uu port and the Un port of the relay device 103 ( Larger value in the Hardware Load Indicator); the higher value of the network side load indicator (SI TL Load Indicator) of the Uu port of the relay device 103 and the SI of the Un port (an interface between the base station and the core network) The larger value of the physical resource block (PRB) occupancy ratio of the Uu port of the relay device 103 and the Un port; the cell capacity level of the Uu port and the Un port of the relay device 103 ( Composite Available Capacity Group) The smaller of the values; the smaller of the available capacity of the Uu port and the Un port of the relay device 103. The resource status information may be a specific value, such as a cell capacity level of 10, or a PRB occupancy ratio of 80%; or an indication information such as an overload or a light load. The Radio Resource Status contains six measured values, which are the Guaranteed Bit Rate (GBR) PRB occupancy (proportional value, indication information, or relative value, etc.), and the uplink and downlink non-guaranteed bit rate (non-GBR). PRB occupancy (proportional value, indication information or relative value, etc.) and total uplink and downlink PRB occupancy (proportional value, indication information or relative value, etc.).

As the second type: The first base station 101 transmits resource state information about the Un port of the relay device 103 to the relay device 103. Specifically, after the first base station 101 forwards the resource status report request sent by the second base station 102 to the relay device 103, the first base station 101 sends the resource status information about the Un port of the relay device 103 to the relay device; or, the first The base station 101 periodically transmits the resource status information about the Un port of the relay device 103 to the relay device 103; or the first base station 101 determines the Un based on the resource status information about the Un port of the relay device 103. When the load state of the port satisfies the preset condition, the resource status information about the Un port is transmitted to the relay device 103. There are a plurality of specific implementation manners for determining that the load status of the Un port meets the preset condition. For example, when the load of the _Un port reaches the preset first load threshold requirement, the Un port is heavily loaded, and the first base station 101 is relayed. The device 103 reports the indication information or the specific resource status value (which may be a direct measurement result) to affect the final reporting resource status information of the relay device 103. When the Un port is restored to a lighter load by a heavier load, When the load of the Un port is less than the preset second load threshold, the first base station 101 also needs to report the indication information or the specific resource status value to the relay device 103, and the Un port measurement result is eliminated from the relay device 103.艮 Resource status information has an impact. The first load threshold and the second load threshold may be determined according to an algorithm, and preferably, in order to prevent Frequent reporting is best to meet certain conditions such as duration.

When the relay device 103 does not receive any indication information of the Un interface or a specific resource status value, or the heavy resource status information is overwritten by the resource state information after the load is alleviated, the relay device 103 may only consider its Uu port. Resource status information is reported.

The first base station 101 can also transmit resource status information about the Un port of the relay device 103 to the relay device 103 at other timings, not enumerated here. The resource status information of the Un port sent by the first base station 101 to the relay device 103 may be a specific value, such as a cell capacity level of 10, or indication information, such as overload or light load, or a relative value, such as a cell capacity. If the level is lower than the level threshold (such as 20) and 10 levels, the actual value of the cell capacity level is 10. The resource status information may be a cell capacity level or a PRB occupancy ratio. Each type of information has its own preset condition. For example, if the cell capacity level is lower than the level threshold, the PRB occupancy ratio is higher than the preset. The proportional threshold is a preset condition.

The first base station 101 receives the resource status information about the Uu port and the Un port of the relay device 103 sent by the relay device 103, and particularly receives the Uu port carried by the relay device 103 and carried by the relay device 103 through the X2 interface. Resource status update signaling of resource status information of the Un port. The resource status update signaling may carry resource status information about the Uu interface and the Un interface of the relay device 103, or carry resource status information that has the greatest impact on load balancing among the resource status information of the Uu interface and the Un interface of the relay device 103. . The first base station 101 updates the content of the relevant domain of the signaling proxy function in the resource status update signaling to the content related to the second base station 102, and transmits the updated resource status update signaling to the second base station 102. The first base station 101 needs to maintain the mapping relationship between the X2 signaling between the first base station 101 and the relay device 103 and the X2 signaling between the first base station 101 and the second base station 102, for example, storing mapping information. When the first base station 101 receives the corresponding X2 signaling sent by the relay device 103, and finds the mapping relationship, it can be known that this is the X2 signaling associated with the second base station 102, and the content of the related domain is updated accordingly. After the proxy function, the X2 signaling is sent out.

The relay device 103 is configured to receive the resource status report request sent by the first base station 101 and sent by the second base station 102, and send the resource status update signaling that carries the resource status information about the Uu port and the Un port of the relay device 103. The first base station 101 is sent to the first base station 101 to forward the resource status update signaling to the second base station 102; or the resource status update signaling carrying the resource status information about the Uu interface of the relay device 103 is sent to the first A base station 101 is configured such that the first base station 101 forwards resource status update signaling carrying resource status information about the Uu port and the Un port of the relay device 103 to the second base station 102.

After receiving the resource status report request, the relay device 103 may also feed back the resource status response signal to the first base station 101, and the first base station 101 forwards the resource status response signaling to the second base station 102.

The configuration and reporting of the resource status information of the Un port between the first base station 101 and the relay device 103 can be retrieved.

For X2 signaling, Radio Resource Control (RRC) signaling can also be captured. If the resource status request signaling, the resource status response signaling (RESOURCE STATUS RESPONSE), and the resource status update signaling between the first base station 101 and the relay device 103 use X2 signaling, it needs to be distinguished from the existing signaling. Therefore, the value of the domain used to identify signaling in signaling needs to be Same as existing values. The fields used for identification signaling include a message type, a registration request, or a report characteristics. In the prior art, the resource status information of the other party (mainly the resource status information of the Uu interface) needs to be obtained between the first base station 101 and the relay device 103, and the resource status request signaling, the resource status response signaling, and the resource status are also sent. Update signaling. The embodiment multiplexes the process of transmitting the resource status request signaling, the resource status response signaling, and the resource status update signaling between the first base station 101 and the relay device 103, and multiplexes the structure of the original signaling to implement Requests and feedback for resource status information for the Uu and Un ports. The existing process of obtaining the resource state information between the first base station 101 and the relay device 103 is determined by the different values of the domain of the signaling, or is obtained between the first base station 101 and the relay device 103 in this embodiment. The process of resource status information about the Un port.

Since the first base station 101 can directly obtain the resource status information of the Un interface by using the measurement, the relay device 103 can directly obtain the resource status information of the Uu interface by using the measurement, and obtain the resource status information of the Uu interface and the Un interface. Specific implementation.

For the first case described above, the relay device 103 transmits the resource status information of the Uu port to the first base station 101. Specifically, the relay device 103 sends the resource status update signaling carrying the resource status information of the Uu port to the first base station 101 through the X2 interface. The relay device 103 can periodically measure and obtain the resource status information of the Uu interface, and then send the resource status information of the Uu interface to the first base station 101.

For the second case described above, the relay device 103 receives the resource status information about the Un port of the relay device 103 transmitted by the first base station 101. Specifically, the relay device 103 receives, by using the X2 interface, a resource status update message (RESOURCE STATUS UPDATE) sent by the first base station 101 and carrying resource status information about the Un port of the relay device 103. The resource status update message may use the structure of the existing resource status update message, but needs to be distinguished from the existing resource status update message, so the value of the field used to identify the signaling in the resource status update message needs to be different from the existing one. value. The fields used for identification signaling include a message type, a registration request, or a report characteristics. The relay device 103 parses the resource status update message and extracts the resource status information of the Un port therefrom. The relay device 103 also obtains the resource status information of the Uu interface from the local area, and sends the resource status update signaling carrying the resource status information about the Uu port and the Un port to the first base station 101. The resource status update signaling may carry the resource status information of the Uu interface and the Un interface, or carry the resource status information that has the greatest impact on the load balance in the resource status information of the Uu interface and the Un interface. When the resource status information that has the greatest impact on the load balancing in the resource status information of the Uu interface and the Un interface is carried, the relay device 103 uses the resource status information of the Uu interface obtained locally and the resource status of the received Un interface. The information is compared to determine the resource state information that has the greatest impact on the load balancing in the resource state information of the Uu interface and the Un interface of the relay device, and the resource state update signaling that carries the determined resource state information that has the greatest impact on the load balancing. It is sent to the first base station 101.

The first base station 101 may periodically send the resource status information about the Un port of the relay device 103 to the relay device 103, and may also determine that the load status of the Un port is satisfied according to the resource status information about the Un port of the relay device. When the preset condition is met, the resource status information of the Un port is transmitted to the relay device 103; therefore, the relay device 103 is obtained according to the last time. The resource status information of the Un port is compared with the resource status information of the locally obtained Uu port. When the first base station 101 uses the preset condition to determine the solution, especially when the first base station 101 sends a relative value, the relay device 103 needs to have a preset condition and obtain an actual value according to the relative value. It is then compared with the resource status information of the locally obtained Uu port. When the first base station 101 sends the indication information, the relay device 103 also needs to obtain the indication information of the resource status of the Uu interface, and then compare the two. When the first base station 101 uses the preset condition to determine the solution, the relay device 103 does not receive a certain resource status information, such as not receiving the PRB occupancy ratio, or receives a certain resource status information has been restored. When the preset condition information is specified, the resource of the Un port is sufficient, and only the resource status information of the Uu port is reported, or the resource status information of the Un port is defaulted to one that does not affect the load balancing judgment. The value is then compared with the resource status information of the Uu interface, so that the comparison result is: determining that the resource status information of the Uu interface is the greatest impact on the load balancing in the resource status information of the Uu port and the Un port of the relay device. Resource status information.

The processing module 203 is configured to update the content of the relevant domain of the signaling proxy function in the resource status report request according to the relay device 103.
