In a traditional mobile communication system, a wireless user equipment (wireless user equipment) will judge whether to upload a measurement report (measurement report) to the network end according to the signal channel quality (signal channel quality), so as to request connection resources from the network end ( resource). The aforementioned signal channel quality can be retry ratio (retry ratio), received signal strength indicator (received signal strength indicator, RSSI), reference signal received power (reference signal received power, RSRP), reference signal received quality (reference signal received quality , RSRQ), packet error rate (packet error rate, PER), bit error rate (bit error rate, BER), or other various parameters to measure.

The signal channel quality will change with the movement of the wireless user equipment or the change of the signal environment, so the wireless user equipment often uploads multiple measurement reports to the network side in succession. However, it takes time for the network to process the measurement report uploaded by the wireless user equipment, and the wireless user equipment may also be in a mobile state. Therefore, the connection resource settings assigned by the network to the wireless user equipment are often not the closest to the current location of the wireless user equipment. How the environment is set up. In this case, it is easy to cause connection interruption or call interruption of the wireless user equipment.

In other words, the information generation circuit 125 and the information sorting circuit 126 in the control circuit 124 can be realized by different circuits, or can be integrated into a single circuit.

For convenience of illustration, other components and connections in the mobile communication system 100 are not shown in FIG. 1 .

It can be known from the foregoing description that the wireless user equipment 120 can communicate with the communication station 110 using the first wireless access technology, and can communicate with the access point using the second wireless access technology. In practice, the first wireless access technology refers to one or more wireless wide area network (wireless wide area network, WWAN) technologies, wireless metropolitan area network (wireless metropolitan area network, WMAN) technologies, or other technologies applicable to larger The wireless communication technology of the communication range, for example, WiMAX, GSM, UMTS, HSPA, LTE, LTE-Advanced, or other 3GPP wireless access technologies. The second wireless access technology refers to one or more wireless area network (wireless wide area network, WLAN) technologies, or other wireless communication technologies applicable to a communication range smaller than that of the first wireless access technology, for example, IEEE802. 11 series of technical standards for wireless access technology.

For the sake of illustration, it is assumed below that the first radio access technology refers to one of various 3GPP radio access technologies. In this case, the communication station 110 can be realized by a 3GPP base station (or BS for short), such as Node B (Node B) or evolved Node B (Evolved Node B, eNodeB or eNB for short). In addition, the communication station 110 may also be disposed at substantially the same location as one or more access points.

During operation, the control circuit 124 of the wireless user equipment 120 will successively generate various types of radio resource control messages (radio resource control messages, RRC messages), and store these radio resource control messages in the message queue of the memory device 123 In order to transmit to the communication station 110 at an appropriate time.

The known wireless user equipment usually adopts a first-in-first-out (FIFO) method to determine the transmission order of the radio resource control information in the information queue.

In order to make the connection resource setting assigned by the mobile communication system 100 to the wireless user equipment 120 closer to the current environment of the wireless user equipment 120, the control circuit 124 will dynamically adjust the radio resource control information in the information queue of the memory device 123. Transmission order, instead of using the traditional first-in-first-out method to determine the transmission order. The method for the control circuit 124 to dynamically adjust the transmission order of the RRC information in the information queue will be further described below with reference to FIG. 2 .

FIG. 2 is a simplified flow chart of an embodiment of a method for dynamically adjusting the transmission sequence of RRC information according to the present invention. In the flow chart of FIG. 2 , the process in the column of a specific device represents the process performed by the specific device. For example, the part in the column marked "information generating circuit" represents the process performed by the information generating circuit 125; the part in the column marked "information sorting circuit" represents the process performed by the information sorting circuit 126.

In the process 202, the information generation circuit 125 in the control circuit 124 responds to the change of the signal channel quality or according to the instruction of a certain communication station (maybe the communication station 110 or other communication stations) in the mobile communication system 100 , and generate a first radio resource control message (RRC message) MSG_A. The message generating circuit 125 temporarily stores the first RRC message MSG_A in the message queue of the memory device 123 .

Next, the message generating circuit 125 performs the process 204 to set a first message identification MID_A and a first priority PRI_A corresponding to the first radio resource control message MSG_A.

Afterwards, when the information generation circuit 125 detects a change in the quality of the signal channel, or receives an instruction from a certain communication station (maybe the communication station 110, or other communication stations), the information generation circuit 125 will proceed to process 206, to generate a second radio resource control message MSG_B. The information generation circuit 125 temporarily stores the second radio resource control information MSG_B in the information queue of the memory device 123 .

In the process 208, the information generating circuit 125 sets a second information identifier MID_B and a second priority PRI_B corresponding to the second radio resource control information MSG_B.

Before using the first wireless communication circuit 121 to transmit the second radio resource control information MSG_B generated by the information generation circuit 125 to the communication station 110 within the signal transmission range of the wireless user equipment 120 at that time, the information sorting circuit 126 will perform processes 210 and 212 .

In the process 210 , the information sorting circuit 126 compares the first priority PRI_A with the second priority PRI_B.

In the process 212, the information sorting circuit 126 arranges the first RRC information MSG_A and the second RRC information MSG_B in the information queue of the memory device 123 according to the comparison result of the first priority PRI_A and the second priority PRI_B order of delivery.

Afterwards, when the information generation circuit 125 detects a change in the signal channel quality, or receives an instruction from a certain communication station (maybe communication station 110, or other communication stations), the information generation circuit 125 will proceed to process 214 , to generate a third radio resource control message MSG_C. The information generating circuit 125 temporarily stores the third radio resource control information MSG_C in the information queue of the memory device 123 .

In the process 216, the information generating circuit 125 sets a third information identifier MID_C and a third priority PRI_C corresponding to the third radio resource control information MSG_C.

Before using the first wireless communication circuit 121 to transmit the third radio resource control information MSG_C to the communication station 110 within the current signal transmission range of the wireless user equipment 120 , the information sorting circuit 126 will perform the processes 218 and 220 .

In the process 218 , the information sorting circuit 126 compares the first priority PRI_A, the second priority PRI_B, and the third priority PRI_C.

In the process 220, the information sorting circuit 126 will re-adjust the transmission order of the RRC information in the information queue of the memory device 123 according to the comparison result of the first priority PRI_A, the second priority PRI_B, and the third priority PRI_C , so that the first wireless communication circuit 121 preferentially transmits the radio resource control information with a higher priority to the communication station 110 .

When the transmitting and receiving circuit 111 of the communication station 110 receives the radio resource control information transmitted from the first wireless communication circuit 121, the processor module 115 of the communication station 110 will judge the current location of the wireless user equipment 120 according to the radio resource control information. signal environment, and assign appropriate connection resource settings to the wireless user equipment 120 through the first wireless communication circuit 121 .

In general, RRC messages can be roughly divided into three categories: RRC connection reconfiguration complete message (RRC connection reconfiguration complete message, hereinafter referred to as RRC connection reconfiguration complete message), messages containing a measurement report (measurement report) data A measurement report message, and other radio resource control messages except the RRC connection reconfiguration completion message and the measurement report message.

In the aforementioned processes 204, 208, and 216, the information generation circuit 125 may base on a specific radio resource control information (for example, the first radio resource control information MSG_A, the second radio resource control information MSG_B, or the third radio resource The type of the control information MSG_C) is used to set a specific information identifier corresponding to the specific RRC information.

For example, if the specific RRC information is not measurement report information, the information generating circuit 125 may set the specific information identifier to a corresponding predetermined value, for example, a value of 0. On the contrary, if the specific RRC information is measurement report information, the information generating circuit 125 may set the specific information identifier to a value other than the predetermined value according to the measurement report type in the measurement report information. In this case, if the specific radio resource control information is RRC connection reconfiguration complete information, or other radio resource control information except RRC connection reconfiguration complete information and measurement report information, the information generating circuit 125 will send the The specific information flag is set to the value 0.

On the contrary, if the specific RRC information is measurement report information, the information generating circuit 125 can set the specific information identifier to a value other than 0. In practice, the measurement report in the measurement report information may be an event trigger report or a periodic report. The foregoing event-triggered report may be one of type A1-A6 reports, or one of type B1-B2 reports. The aforementioned periodic report may be an intra-frequency measurement report, an inter-frequency measurement report, or an inter-RAT measurement report. In an embodiment, the information generating circuit 125 may set the specific information identifier to a value other than 0 according to the measurement report type in the specific RRC information, for example, one of the values 1 to 32, to Therefore, different types of measurement report information correspond to different information identifiers.

In this way, the information sorting circuit 126 can quickly determine whether the corresponding specific RRC information is measurement report information according to the specific information identifier in subsequent processes. When the specific RRC information is measurement report information, the information sorting circuit 126 can also quickly determine the measurement report type in the specific RRC information according to the specific information identifier.

In addition, in the aforementioned processes 204, 208, and 216, the information generating circuit 125 can set a specific priority corresponding to the specific RRC information according to the type of the specific RRC information. For example, if the specific RRC message is an RRC connection reconfiguration complete message, the message generating circuit 125 may set the specific priority as the highest priority level. If the specific RRC information is one of various measurement report information, the information generating circuit 125 may set the specific priority to a middle priority level lower than the aforementioned highest priority level. If the specific radio resource control information is other radio resource control information except RRC connection reconfiguration complete information and measurement report information, the information generating circuit 125 may set the specific priority to be lower than the aforementioned medium priority. Low priority level (lower priority level).

In practice, the information generating circuit 125 can set the priorities corresponding to different types of measurement report information to be the same predetermined priority.

Alternatively, the information generating circuit 125 can set different priorities for different types of measurement report information. For example, the information generation circuit 125 can set different priorities for different types of measurement report information.

For another example, the information generation circuit 125 may divide various measurement report information into different groups, and set the priorities corresponding to different measurement report information in the same group to be the same but different from those in other groups. The priority to which the report message corresponds. For example, the information generating circuit 125 may set the priorities of various measurement report information including event-triggered reports to a first predetermined priority, and set the priorities of various measurement report information including periodic reports to A second predetermined priority different from the aforementioned first predetermined priority. In one embodiment, the information generating circuit 125 may set the priority level of the first predetermined priority to be higher than that of the second predetermined priority.

It can be seen from the foregoing description that if the first RRC information MSG_A is an RRC connection reconfiguration completion information, the third RRC information MSG_C is a measurement report information, and the second RRC information MSG_B is not an RRC connection reconfiguration completion information information or a measurement report information, the information generating circuit 125 can set the aforementioned first priority PRI_A to be higher than the second priority PRI_B and the third priority PRI_C, and set the third priority PRI_C to be lower than the first The priority PRI_A is higher than the second priority PRI_B.

In another embodiment, if the first radio resource control information MSG_A is RRC connection reconfiguration completion information, the third radio resource control information MSG_C is a first measurement report information including an event triggered report, and the second radio resource The control information MSG_B is a second measurement report information including a periodic report, then the information generation circuit 125 can set the aforementioned first priority PRI_A higher than the second priority PRI_B and the third priority PRI_C, and set the first The third priority PRI_C is set lower than the first priority PRI_A and higher than the second priority PRI_B.

In another embodiment, if the first radio resource control information MSG_A is RRC connection reconfiguration completion information, the third radio resource control information MSG_C is a third measurement report information including a periodic report, and the second radio resource The control information MSG_B is a fourth measurement report information including an event-triggered report, and the information generation circuit 125 can set the aforementioned first priority PRI_A higher than the second priority PRI_B and the third priority PRI_C, and set the first The third priority PRI_C is set lower than the first priority PRI_A and higher than the second priority PRI_B.

As shown in FIG. 3 , the information sorting circuit 126 compares the first priority PRI_A and the second priority PRI_B in the process 210 to determine whether the second priority PRI_B has a higher priority.

For example, the information sorting circuit 126 can perform the process 302 to determine whether the second priority PRI_B is higher than the first priority PRI_A. If the second priority PRI_B is not higher than the first priority PRI_A, the information sorting circuit 126 will proceed to the process 304 . On the contrary, if the second priority PRI_B is higher than the first priority PRI_A, the information sorting circuit 126 will proceed to the process 306 .

In the process 304, the information sorting circuit 126 determines whether the second priority PRI_B is equal to the first priority PRI_A. If the second priority PRI_B is equal to the first priority PRI_A, the information sorting circuit 126 will proceed to the process 308 . On the contrary, if the second priority PRI_B is different from the first priority PRI_A, it means that the second priority PRI_B is lower than the first priority PRI_A. At this time, the information sorting circuit 126 will proceed to the process 314 .

On the contrary, if the first wireless communication circuit 121 has started to transmit part or all of the data of the first RRC message MSG_A, the message sorting circuit 126 will proceed to the process 314 .

In the process 308, the information sorting circuit 126 determines whether the second information identifier MID_B is equal to the first information identifier MID_A. If the second information identifier MID_B is equal to the first information identifier MID_A, it means that the type of the second radio resource control information MSG_B is the same as that of the first radio resource control information MSG_A, and the second radio resource control information MSG_B is the first radio resource control information MSG_A. The newer version is closer to the current signal environment of the wireless UE 120 than the first RRC information MSG_A.

On the contrary, if the first wireless communication circuit 121 has started to transmit part or all of the data of the first RRC message MSG_A, the message sorting circuit 126 will proceed to the process 314 .

In the process 312, the information sorting circuit 126 arranges the transmission order of the second radio resource control information MSG_B in the information queue of the memory device 123 before the first radio resource control information MSG_A, so that the first radio communication circuit 121 has priority The second RRC message MSG_B with higher priority is transmitted to the communication station 110 .

In the process 314, the information sorting circuit 126 arranges the transmission order of the second radio resource control information MSG_B in the information queue of the memory device 123 after the first radio resource control information MSG_A, so that the first radio communication circuit 121 has priority The first RRC message MSG_A with a higher priority is transmitted to the communication station 110 .

In the process 316, the information sorting circuit 126 replaces the first RRC information MSG_A in the message queue of the memory device 123 with the second RRC information MSG_B, so as to prevent the first wireless communication circuit 121 from using the older first RRC information The resource control information MSG_A is transmitted to the communication station 110 , thereby effectively saving the time for uploading all the radio resource control information to the communication station 110 .

Please refer to FIG. 4 , which is a simplified flowchart of an embodiment of the processes 218 and 220 in FIG. 2 . The operation of the information sorting circuit 126 in the foregoing processes 218 and 220 will be further described below with reference to FIG. 4 .

In the process 406, the information sorting circuit 126 determines whether the third priority PRI_C is equal to the second priority PRI_B. If the third priority PRI_C is equal to the second priority PRI_B, the information sorting circuit 126 will perform the process 416 . On the contrary, if the third priority PRI_C is different from the second priority PRI_B, which means that the third priority PRI_C is lower than the second priority PRI_B, then the information sorting circuit 126 will perform the process 426 .

In the process 412 , the information sorting circuit 126 determines whether the third information identifier MID_C is equal to the first information identifier MID_A. If the third information identifier MID_C is equal to the first information identifier MID_A, it means that the type of the third radio resource control information MSG_C is the same as the type of the first radio resource control information MSG_A, and the third radio resource control information MSG_C is the first radio resource control information MSG_A. The newer version is closer to the current signal environment of the wireless UE 120 than the first RRC information MSG_A. In this case, the information sorting circuit 126 will perform the process 414 .

In the process 416 , the information sorting circuit 126 determines whether the third information identifier MID_C is equal to the second information identifier MID_B.

It can be seen from the foregoing description that the information sorting circuit 126 in the control circuit 124 dynamically adjusts the transmission order of the RRC information in the information queue of the memory device 123 , and abandons the traditional first-in-first-out method. The aforementioned method of dynamically adjusting the transmission order of the radio resource control information can ensure that radio resource control information with a higher priority (for example, RRC connection reconfiguration completion information) can be transmitted to the communication station 110 first, so that the communication station 110 can More important radio resource control information is received earlier.

In addition, the aforementioned method of dynamically adjusting the transmission sequence of the RRC information can also avoid transmitting older and invalid RRC information to the communication station 110, so it can speed up the uploading of newer RRC information to the communication station. 110 progress. In this way, the communication station 110 can respond more quickly to the signal channel environment of the wireless user equipment 120 at that time, so that the subsequent connection resource settings assigned to the wireless user equipment 120 can be closer to the current location of the wireless user equipment 120. signal environment.

Through the above method of dynamically adjusting the transmission sequence of the RRC information, the problem of connection interruption or call interruption of the wireless user equipment 120 can be effectively avoided or reduced.
