Description

Method for reporting radio link-specific measurement results in time division code division multiple access communication system

technical field

The present invention relates to the third generation mobile communication system, especially the measurement results of multiple wireless links in Time Division Code Division Multiple Access (TD-CDMA) system, including multiple time slots of each wireless link , an implementation method for reporting from a Node B (Node B) to a Radio Network Controller (RadioNetwork Controller, RNC).

Background technique

In the TD-CDMA system, RNC needs Node B to perform various measurements, including public measurements and private measurements. The object of the public measurement is the time slot, while the dedicated measurement is aimed at the physical channels of some radio links (Radio Link, RL), and mainly measures the received signal code power (Received Signal Code) of the physical channels of some wireless links. Power, RSCP), Signal Interference Ratio (SIR), Transmit Code Power (TCP) and other measurement quantities. Each RL may occupy multiple time slots, and the measurement results of each time slot are different, and related measurements need to be carried out separately. Each measurement object is identified by a radio link identifier (RL ID) and a dedicated physical channel identifier (DPCH ID) unique correspondence.

As shown in Figure 1, when the RNC needs the Node B to perform some RL dedicated measurement, the RNC sends a "dedicated measurement initialization request" message to the Node B, configures a list of RLs in the message, and uses one or more wireless links The road identification clearly indicates each RL that Node B is required to measure. At the same time, by configuring or not configuring the dedicated physical channel identifier, directly or indirectly indicate the measurement object that Node B is required to measure. The 3GPP protocol stipulates that if each RL in the RL list in the request message does not contain a DPCH ID, the Node B is required to select the corresponding relationship between the RL and the DPCH (that is, which time slots a RL contains) according to the known correspondence between the RL and the DPCH in advance. One DPCH is selected for measurement in each time slot. At this time, the number of measurement objects corresponding to a certain RL is equal to the number of DPCHs included in the RL. If the request message clearly contains RL ID and DPCH ID, Node B is required to measure the relevant information of the measurement object uniquely corresponding to the RL ID and DPCH ID.

When Node B judges that it has the measurement reporting capability of all DPCH related information under all RLs in the request message, Node B sends a "dedicated measurement initialization response" message to RNC, otherwise sends a "dedicated measurement initialization failure" message to RNC.

The Node B can report the measurement results of multiple radio links to the RNC through measurement reporting messages, such as: "dedicated measurement initialization response" message and "dedicated measurement report" message.

According to the protocol, when the "Dedicated Measurement Initialization Request" message contains a list of RLs, and each RL also contains a DPCH ID, the Node B will report the RLIDs in turn for each RL in the RL list in the measurement report message The measurement result of the measurement object corresponding to the DPCH ID.

At the same time, according to the protocol, when the "Dedicated Measurement Initialization Request" message contains a list of RLs, but some RLs do not include DPCH IDs, it indicates that the RNC requires the Node B to measure and report the measurement results of all time slots of these RLs. However, according to the current protocol, there is an RL list in a report message of the measurement results sent by the NodeB to the RNC, such as: "Dedicated Measurement Initialization Response" and "Dedicated Measurement Report" messages, so multiple RL related information can be reported at the same time. However, there is only one DPCH ID information in each RL, so only the measurement result of one time slot of each RL can be reported, and the measurement report of all time slots of one RL cannot be completed.

It can be seen that the current protocol only supports the reporting of the measurement result of a single time slot in multiple RLs, and does not support the reporting of the measurement results of multiple time slots in multiple RLs.

Contents of the invention

The technical problem solved by the present invention is that in the prior art, when the Node B reports the measurement results to the RNC, if multiple wireless links need to be reported, and the wireless links include multiple time slots, the measurement results cannot be completely reported.

In order to solve the above-mentioned technical problems, the present invention proposes a method for reporting dedicated measurement results of wireless links in a time division code division multiple access communication system, which specifically includes the following steps:

Step 1, the radio network controller sends a dedicated measurement request message to the node B, and the message includes a list of radio links;

Step 2, if the Node B has the ability to report the measurement results of all radio links, continue to Step 3, otherwise, the Node B sends a message of "dedicated measurement initialization failure" to the radio network controller;

Step 3, Node B reports the measurement result, which contains a radio link list, listing the measurement results of each radio link, if the radio link information in the dedicated measurement request message contains a dedicated physical channel identifier, the radio link The measurement result of the radio link is the measurement result of the dedicated physical channel. If the wireless link information in the dedicated measurement request message does not contain the dedicated physical channel identifier, a dedicated physical channel list is set in the measurement result of the wireless link to reflect all of its Timeslot measurement results.

In the above method, if the dedicated measurement request message sent by the radio network controller requires the response message to include the measurement result, the measurement result reported by the Node B in step 3 is included in the "dedicated measurement initialization" message sent to the radio network controller. Response" message.

In the above method, if the dedicated measurement request message sent by the radio network controller does not require the response message to include the measurement result, the Node B reports the measurement result in step 3 by first sending a "dedicated measurement initialization response" message that does not include the measurement result to the radio network controller, and then send a "special measurement report" including the measurement result to the radio network controller when the measurement report condition is satisfied.

The method provided by the invention reflects the measurement results of all time slots of the RL by setting a dedicated physical channel list in the measurement results, effectively solving the problems in the prior art, and realizing the reporting of the measurement results of multiple time slots of multiple RLs.

Detailed ways

The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

RNC sends a dedicated measurement request message to Node B, which includes a radio link list, and the RLIDs in the list are different, but some RLs do not include dedicated physical channel identifiers. This means that RNC requires Node B to report the measurement results of all time slots of these RLs, and Node B arbitrarily selects a DPCH for measurement in each time slot.

If Node B does not have the reporting capability for all radio link measurement results, Node B sends a "dedicated measurement initialization failure" message to RNC, otherwise Node B sends a "dedicated measurement initialization response" message to RNC to report the measurement results, measurement results contains a wireless link list, listing the measurement results of each wireless link, if the wireless link information in the dedicated measurement request message contains the dedicated physical channel identifier, then the measurement result of the wireless link is the measurement result of the dedicated physical channel As a result, if the radio link information in the dedicated measurement request message does not include the dedicated physical channel identifier, the measurement result of the radio link includes a list of dedicated physical channels reflecting the measurement results of all its time slots.

As shown in Figure 2, the message that Node B reports the measurement result to RNC contains an RL list (this list is the same as the RL list in the "dedicated measurement initialization request" message). Wherein, each RL contains a DPCH list (this list specifies the DPCHs on all time slots used by the RL), and the measurement results corresponding to each RLID and DPCH ID. All RLs in the report message form an RL list (indicated by different RL IDs), and each RL in the list (corresponding to an RL ID) includes a DPCH list (indicated by different DPCH IDs). The report message can use the RL ID and DPCH ID to uniquely mark the measurement result of a measurement object by including the double list of RL and DPCH. That is: any RL is configured with a DPCH list to report the measurement result of the RL; all RLs can report the measurement results of all RLs through the RL list.

The reporting methods of measurement results include: "Special Measurement Initialization Response" and "Special Measurement Report".

When the response message sent by the Node B needs to contain measurement results according to the requirements of the "dedicated measurement initialization request" message, such as: when the reporting criterion of the "dedicated measurement initialization request" message is "on demand", and the request message does not contain When the connection frame number is included, the Node B sends a "dedicated measurement initialization response" message containing the measurement result to the RNC.

When the response message sent by Node B does not need to contain measurement results according to the requirements of the "dedicated measurement initialization request" message, the "dedicated measurement initialization response" message sent by Node B does not contain the measurement results, and the When measuring the reporting condition, send a "special measurement report" containing the measurement result to the RNC.

Let's give an example and describe the implementation method of the present invention in detail:

RNC requires Node B to perform dedicated measurement, specifically, for 2 RLs (denoted as RL1 and RL2), RL1 contains 2 time slots (denoted as TS1, TS4, select DPCH1 measurement on TS1, select DPCH4 measurement on TS4), RL2 Including 1 time slot (marked as TS5, this time slot is selected for DPCH5 measurement).

RNC sends a "dedicated measurement initialization request" message to Node B, and the reporting criterion contained in the message is "periodic report"; the message includes the RL list (2 RL IDs: RL1 and RL2), and does not include the DPCH ID.

RNC requires Node B to report all DPCH measurement results of RL1 and RL2 in the measurement result reporting message. Specifically, measurement reporting is required: the measurement results of the three measurement objects corresponding to RL1-DPCH1, RL1-DPCH4, and RL2-DPCH5.

Node B first judges whether it has the measurement capability of all DPCHs of these RLs, and if so, sends a "dedicated measurement initialization response" message, otherwise sends a "dedicated measurement initialization failure" message.

Subsequently, when the measurement report condition is satisfied (the reporting time is up), the "special measurement report" sent by the Node B includes an RL list, in which the RL ID is the same as the request message (also RL1 and RL2), in each One DPCH list is included under the RL, specifically, the DPCH lists in RL1 are DPCH1 and DPCH4, and the DPCH list in RL2 is DPCH5. pass

RL1-DPCH1: Measurement result 1

RL1-DPCH4: Measurement result 2

RL2-DPCH5: Measurement result 3

It can correspond to the measurement results of three measurement objects, so that the measurement reporting of multiple time slots of two RLs can be implemented in one report message.
