Problems solved by technology

In this case, since the RNC cannot correctly obtain the unavailable time slot information of the Node-B, when the wireless link designated by the RNC is established on a time slot not supported by the Node-B, the wireless link establishment will inevitably fail.
Usually a wireless link is carried on multiple time slots at the same time. As long as one of the time slots is unavailable, the wireless link establishment will fail. In this case, the success rate of wireless link establishment will be greatly reduced, which will greatly affect the system. access performance

[0035] Such as Figure 4 As shown, in this embodiment, resource reporting is carried out through resource auditing in the TD-SCDMA system, and the resource reporting and control process includes the following steps:

[0036] Step 110, Node-B receives the resource audit request sent by RNC, and finds the designated cell of the audit request;

[0037] Step 120, Node-B obtains the number and number of uplink and downlink time slots according to the physical resource information stored in the cell;

[0038] Step 130, Node-B calculates the resource capability value of each uplink and downlink time slot, which is equal to the number of code channels when SF=16 is simulated on the time slot, that is, equal to the number of code channels×(16 / spreading factor). The resource capability value is greater than or equal to 0 and less than or equal to 16. For unavailable time slots, the value is 0;

[0039] Step 140, Node-B fills in the resource capability of each time slot (with unique id...

[0044] Different from the first embodiment, this embodiment reports resources through resource status indication, and the resource reporting and control process includes the following steps:

[0045] Step 210, the Node-B discovers that the internal resources of the cell have changed;

[0046] Step 220, Node-B obtains the number and number of uplink and downlink time slots according to the physical resource information stored in the cell;

[0047] Step 230, Node-B calculates the resource capability value on each uplink and downlink time slot, which is equal to the number of code channels when the time slot is simulated as SF=16, and the resource capability value is greater than or equal to 0 and less than or equal to 16. With time slot, the value is 0;

[0048] Step 240, Node-B fills in the resource capability of each time slot (with a unique identifier), and sends it to RNC through a resource status indication message;

[0049]Step 250, after the RNC receives the resource st...

Abstract

This invention provides a method for reporting and controlling inexhaustible resource, which comprises the following steps: a) the base station will get the time slot according to the resource condition of the block, and compute the resource ability according to the code information of every time slot; b) the base station will report the resource ability to the wireless network controller; c) after receiving the information, the wireless network controller will get the code information of every time slot according to the resource ability information; d) when building the business resource of the user, the wireless network controller can get the resource ability according to the business character of the user, comparing with the time slot and the code information of the time slot, distributing resource for the business. By said method, the wireless network controller can get the resource ability information of every time slot in base station.

Description

technical field [0001] The invention relates to a method for reporting and controlling wireless resources, in particular to a method for reporting and controlling wireless resources between a base station (Node-B) and a radio resource controller (RNC) in a time division multiplexing system. Background technique [0002] In the third generation mobile communication system, such as Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, radio resources are usually controlled by RNC. The basis for the RNC to control the radio resources is the resource reporting situation of the Node-B. Therefore, whether the Node-B reports sufficient and accurate resource information to the RNC is the key to correct resource control. [0003] The Node-B reports resources to the RNC through the Iub interface usually in two ways: resource status indication and resource audit. [0004] When the dedicated resource of the local cell in the Node-B direction changes, it will notif...
