Problems solved by technology

In the prior art, for sharing CE capabilities between different local cells, both messages support reporting by local cell group, and a local cell can only be in one local cell group, and cannot report the LICENSE capability of a base station
That is, it cannot reflect the actual hardware resource capability and license capability of a base station at the same time. In this case, if the license capability of a base station is 64CE, the base station has two local cell groups, where local cell group 0 has 128CE, and local cell group 1 If there are 32CEs, if the base station only reports the LICENSE capability, tell the base station controller that the base station can handle up to 64 CEs at the same time. For users in the local cell group 0, there is no problem with the support of the license capability or the actual hardware capability, but for the local cell Users in group 1 can only support up to 32CE at the same time
In this way, the capacity resource status reported by the base station is inaccurate, which may cause the base station controller to fail to implement the scheduling algorithm based on processing capabilities among different base stations, such as admission control, etc., resulting in an increased probability of service establishment failure and affecting user experience.

Embodiment 1

[0010] If the base station side is configured with the LICENSE capability, an additional resource group IE: Local Cell Group Information is carried in the RESOURCE STATUSINDICATION signaling message, and the Local Cell Group ID is assigned in this IE. When assigning a value, you can select a special value that is generally not used by the system in the signaling message, that is, a special value that is rarely used by the system. For example, the legal range of the local cell group number in the current IUB interface is 0~maxLocalCellinNodeB-1. In the 3GPP 25.433 protocol, maxLocalCellinNodeB is defined as 256, but in the actual networking, each manufacturer cannot reach 256 local cells in a base station, so the value of maxLocalCellinNodeB-1 is also a special value rarely used by the system. information, it can be used to indicate LICENSE capability information. According to the provisions of the 3GPP 25.433 protocol, the possible value ranges of each parameter in the RESOURC...

Embodiment 2

[0016] If the base station side is configured with the LICENSE capability, an additional resource group IE: Local Cell Group Information is carried in the AUDIT RESPONSE signaling message. In this IE, the LocalCell Group ID is generally a special value rarely used by the system. According to the 3GPP 25.433 protocol The possible value ranges of each parameter in the AUDIT RESPONSE signaling message are as follows:

[0017] Range Bound Explanation maxCellinNodeB Maximum number of Cells that can be configured in Node B maxCCPinNodeB

Maximum number of Communication Control Ports that can exist in the

Node B maxLocalCellinNodeB Maximum number of Local Cells that can exist in the Node B maxSCPlCHCell Maximum number of Secondary CPICHs that can be defined in a Cell. maxSCCPHCell Maximum number of Secondary CCPCHs that can be defined in a Cell maxFACHCell Maximum number of FACHs that can be defined in a Cell maxPRACHCell ...

[0021] If the base station side is configured with the LICENSE capability, it can also carry the LICENSE capability information by adding an extension field in the corresponding signaling message. For example, in the AUDIT RESPONSE signaling message, the LICENSE capability information indication field can be added in the following manner,

[0022] AuditResponse-Extensions NBAP-PROTOCOL-EXTENSION::={

Abstract

Using RESOURCE STATUS INDICATION signaling message or AUDIT RESPONSE signaling message carries LICENSE capability indication information (CII) and reports CII to base station controller. Concretely, it is realized by using the said signaling messages to carry resource group IE, and setting up Local Cell Group ID as systemic uncommon specific value in signaling message or adding field to carry CII. The invention makes software capability limited base station possible to report actual capability and rules of resource expenditure precisely. Thus, base station controller can master resource capability and condition of use in base station accurately in order to use techniques that need to know condition of resource use of base station in advance such as admittance control etc.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for reporting the LICENSE capability of a base station. Background technique [0002] A base station may have multiple devices that can independently process calls. Each independent device has a capability, that is, how many 12.2K voice calls it can support. For example, an independent device can handle up to 128 12.2K voice calls at the same time, then Let us say that the capability of the device is 128CE (ChannelElement, resource capability points consumed by 12.2K voice services). Since this device is the smallest unit of call processing and cannot be divided, operators may consider the actual user capacity at the initial stage of network construction and do not need the entire device capability. For example, only 32 CEs are enough to meet the current market demand. A concept of base station soft capability. This capability can be purchased independently of the ...
