Description

A method and device for inter-system redirection

technical field

The invention relates to the communication field, in particular to a method and device for inter-system redirection.

Background technique

The continuous evolution of mobile communication technology not only improves the communication capacity of the wireless system, but also brings beneficial effects on the use of terminals. However, with the explosive growth of data traffic in recent years, service personnel have to upgrade the network to meet the terminal's demand for data traffic. In this way, they need to face the problems of multiple networks such as 2G, 3G, and 4G at the same time.

2G and 3G networks have been built for a long time, and the coverage is relatively complete, while the coverage of the just-started 4G network is relatively poor. In terms of data transmission rate, 4G network is higher than 3G network, and 3G network is higher than 2G network. In order to ensure the efficiency of terminal use, on the one hand, data services should be carried by the high-speed network as much as possible; on the other hand, when there is no suitable neighboring cell in the high-speed network and the signal quality of the serving cell is poor, it will initiate a network with more perfect coverage. Different system redirection for low-speed networks.

Referring to Figure 1, the specific process of different system redirection in the prior art is as follows:

Step 100: the base station delivers parameter configuration information for inter-system redirection to the terminal through a radio resource control (RadioResourceControl, RRC) message.

Step 110: The terminal judges whether the quality of the received signal meets the conditions set by the different system redirection parameters.

When step 110 is executed, if it is satisfied, then step 120 is executed; otherwise, the redirection process ends.

Step 120: the terminal reports an event report to the base station.

Specifically, the event report may be a different system measurement event report or a blind redirection event report.

Step 130: the base station sends a redirection command message to the terminal according to the event report, and the terminal accesses the redirection network.

However, in the prior art, only judging whether to perform an inter-system redirection operation based on the received signal quality of the terminal cannot guarantee the service quality of the terminal to the maximum extent.

For example, when the received signal quality of the terminal is poor, the data transmission rate of the high-speed network where the terminal is located may still be faster than the data transmission rate of the low-speed network. In this case, inter-system redirection is not required operate.

detailed description

In order to reduce the load of the low-speed network and improve the service quality of the terminal, in the embodiment of the present invention, a method of inter-system redirection is proposed: according to the fact that the received signal of the terminal is lower than the threshold of the system in the redirection parameter threshold and the actual high The redirection command is issued to the terminal when the different system threshold in the redirection parameter threshold and the data transmission rate is actually lower than the preset data transmission rate threshold. The terminal sends a redirection event report to the base station, and the redirection event report further records information related to the data transmission rate of the terminal; the terminal receives a redirection instruction issued by the base station, and starts to execute a redirection process.

Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 2, in the embodiment of the present invention, the overview flow of redirection between systems on the network side is as follows:

Step 200: the base station sends preset redirection parameter thresholds and data transmission rate thresholds to the terminal; wherein, the redirection parameter thresholds include local system thresholds and different system thresholds.

In this embodiment, when step 200 is executed, the base station may send a preset redirection parameter threshold to the terminal through an RRC message.

Specifically, the base station may send the preset redirection parameter threshold to the terminal through various information elements in the RRC message.

For example, the preset redirection parameter threshold can be sent to the terminal through an existing cell; the preset redirection parameter threshold can also be sent to the terminal through a new cell; and the terminal can also be sent to the terminal through a reserved cell. The preset redirection parameter threshold.

When the base station sends the preset data transmission rate threshold to the terminal, it can use but not limited to the following two methods:

The first way: the base station sends a preset data transmission rate threshold to the terminal through an RRC message.

Specifically, the base station may send to the terminal a preset data transmission rate threshold through various information elements in the RRC message;

For example, the preset data transmission rate threshold can be sent to the terminal through existing cells; the preset data transmission rate threshold can also be sent to the terminal through new cells; the preset data transmission rate threshold can also be sent to the terminal through reserved cells. Data transfer rate threshold.

The second way: the base station sends a preset data transmission rate threshold to the terminal through a broadcast message.

Specifically, the base station sends the preset data transmission rate threshold to the terminal through various information elements in the broadcast message.

For example, the preset data transmission rate threshold can be sent to the terminal through the existing cells in the broadcast message; the preset data transmission rate threshold can also be sent to the terminal through a new cell; Send preset data transfer rate threshold.

In the embodiment of the present invention, the RRC message may be a radio resource control connection establishment message (RRCConnectionSetup), may also be a radio resource control connection reconfiguration message (RRCConnectionReconfiguration), and may also be a radio resource control connection reestablishment message (RRCConnectionReestablishment).

The broadcast message can be a master information block (MasterIndicationBlock, MIB) or a system information block (Systeminformationblock, SIBs).

The following takes the RRCConnectionReconfiguration message as an example for specific description. In the 3rd Generation Partnership Project (The3rdGenerationPartnershipProject, 3GPP) specification, the abstract syntax notation (AbstractSyntaxNotationOne, ASN1) data format of the RRCConnectionReconfiguration message is as follows:

Therefore, the base station can send the preset redirection parameter threshold and data transmission rate threshold to the terminal through the reserved cells at any position such as spare1~spare7 of the message; ” and other existing cells to send preset redirection parameter thresholds and data transmission rate thresholds to terminals; new cells derived from the original 3GPP specifications can also be used to send preset redirection parameter thresholds and data transmission rates to terminals rate threshold.

Step 210: the base station receives the redirection event report reported by the terminal.

In the embodiment of the present invention, the base station receives the redirection event report reported by the terminal through the measurement message.

Specifically, the terminal may report the redirection event report through various information elements in the measurement message. For example, the redirection event report may be reported through an existing cell; the redirection event report may also be reported through a new cell, or the redirection event report may be reported through a reserved cell.

The following takes the MeasurementReport message as an example for specific description. In the 3GPP specification, the ASN1 data format of the MeasurementReport message is as follows:

Therefore, the terminal can report redirection report events through reserved cells such as spare1~spare7 in MeasurementReport; it can also report redirection reports through existing cells such as "measurementReport-r8" or "MeasurementReport-r8-IEs" Events; redirection report events can also be reported through new cells derived from the original 3GPP specifications.

Step 220: The base station determines according to the redirection event report that the received signal quality of the terminal is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the different system threshold in the redirection parameter threshold, and further determines the terminal according to the redirection event report When the data transmission rate is actually lower than the preset data transmission rate threshold, a redirection command is issued to the terminal.

In the embodiment of the present invention, when performing step 220, the following two methods can be adopted but not limited to:

The first method: the base station first determines that the received signal quality of the terminal is recorded in the redirection event report, and then determines that the received signal quality of the terminal is actually lower than the threshold of the system in the redirection parameter threshold and actually higher than the threshold in the redirection parameter threshold Different system threshold;

When it is determined that the data transmission rate of the terminal is recorded in the redirection event report or the comparison result between the data transmission rate of the terminal and the preset data transmission rate threshold is recorded, it is determined that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold;

Then issue a redirection command to the terminal.

Of course, in the first manner, the base station may first determine the terminal's data transmission rate when the data transmission rate of the terminal is recorded in the redirection event report or the comparison result between the terminal's data transmission rate and the preset data transmission rate threshold is recorded. The data transmission rate is actually lower than the preset data transmission rate threshold; and when it is determined that the received signal quality of the terminal is recorded in the redirection event report, it is determined that the received signal quality of the terminal is actually lower than the threshold of the system in the redirection parameter threshold and the actual It is higher than the foreign system threshold in the redirection parameter threshold. Alternatively, the base station may also determine that when the received signal quality of the terminal is recorded in the redirection event report, it is determined that the received signal quality of the terminal is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the foreign system in the redirection parameter threshold Threshold; at the same time, when determining the data transmission rate of the terminal recorded in the redirection event report or the comparison result between the data transmission rate of the terminal and the preset data transmission rate threshold, it is determined that the data transmission rate of the terminal is actually lower than the preset Data transfer rate threshold.

That is, the execution sequence of the above two steps is not strictly limited, and will not be repeated here.

Wherein, when the base station determines that the received signal quality of the terminal is recorded in the redirection event report, it specifically means that the terminal determines that its own received signal quality is actually lower than the threshold of the system in the redirection parameter threshold and is actually higher than the redirection parameter threshold. When the different system threshold is exceeded, the received signal quality at this time is recorded in the redirection report.

When the base station determines that the data transmission rate of the terminal is recorded in the redirection event report or the comparison result between the data transmission rate of the terminal and the preset data transmission rate threshold is recorded, it specifically means that the terminal determines that its own data transmission rate is lower than the preset threshold. When the data transmission rate threshold is set, record the current data transmission rate in the redirection report or record the comparison result of the two in the redirection report.

For example, the signal quality of the 4G network signal received by the terminal is -120dBm, and the measured signal quality of the 3G network is -75dBm. The threshold is -80dBm. At this time, the received signal quality of the terminal is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the different system threshold in the preset redirection parameter threshold, and the received signal quality of the terminal is -120dBm and The measured signal quality of the 3G network -75dBm is recorded in the redirection report event. At the same time, if the data transmission rate of the terminal is 500Kbps, and the preset data transmission rate threshold is 1Mbps, then the terminal will transmit data at a rate lower than the preset The comparison result of the data transmission rate threshold is also recorded in the redirection report event, and the current data transmission rate of 500 Kbps may also be recorded in the redirection report event. At this time, after receiving the redirection report, the base station issues a redirection instruction to the terminal.

The second method: the base station first determines that the received signal quality of the terminal is recorded in the redirection event report, and then determines that the received signal quality of the terminal is actually lower than the threshold of the system in the redirection parameter threshold and actually higher than the threshold in the redirection parameter threshold. Different system threshold;

Then, according to the terminal's data transmission rate recorded in the redirection event report, compare the terminal's data transmission rate with the preset data transmission rate threshold, and determine that the terminal's data transmission rate is actually lower than the preset data transmission rate based on the comparison result rate threshold;

Then issue a redirection command to the terminal.

For example, the signal quality of the 4G network received by the terminal is -120dBm, the measured signal quality of the 3G network is -75dBm, the threshold of the system in the redirection parameter threshold is -116dBm, and the threshold of the different system in the redirection parameter threshold is -80dBm. At this time, the received signal quality of the terminal is actually lower than the threshold of the system in the preset redirection parameter threshold and actually higher than the threshold of the different system in the redirection parameter threshold. The received signal quality of the terminal is -120dBm and The measured signal quality of the 3G network -75dBm is recorded in the redirection report event. Further, the data transmission rate of the terminal is further recorded in the redirection report, assuming it is 500Kbps. Then, after the base station receives the redirection report, it will The transmission rate of the terminal is compared with the preset data transmission rate threshold. Assuming that the preset data transmission rate threshold is 1 Mbps, it is obtained that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold. At this time, the base station downloads to the terminal Send a redirect command.

On the other hand, when the base station receives the received signal quality of the terminal recorded in the redirection event report, it directly determines that the received signal quality of the terminal is actually lower than the threshold of the system in the redirection parameter threshold and actually higher than the threshold in the redirection parameter threshold. The different system threshold, wherein the redirection event report is the first time when the terminal determines that the quality of the received signal is lower than the local system threshold in the redirection parameter threshold and greater than the different system threshold in the redirection parameter threshold, and the maintenance time exceeds the preset first time Recorded at threshold time;

At the same time, the base station further determines that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold according to the redirection event report, and the following two methods can be adopted:

The first method: the base station receives the data transmission rate of the terminal recorded in the redirection event report or the comparison result between the data transmission rate of the terminal and the preset data transmission rate threshold, and directly determines that the data transmission rate of the terminal is actually lower than the preset The data transmission rate threshold, wherein the redirection event report is recorded when the terminal determines that the data transmission rate is lower than the preset data transmission rate threshold and the maintenance time exceeds the preset second time threshold.

For example, if the base station receives the data transmission rate threshold of the terminal recorded in the redirection report as 1 Mbps, it can directly determine that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold.

For another example, the base station receives the comparison result between the data transmission rate of the terminal recorded in the redirection report and the preset data transmission rate threshold, and records the comparison result as "<", then the base station will use the "<" in the comparison record to , it can be directly determined that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold.

The second way: the base station further determines according to the data transmission rate of the terminal recorded in the redirection event report that the data transmission rate of the terminal is lower than the preset data transmission rate threshold, and when the maintenance time exceeds the preset second time threshold, determine The data transmission rate of the terminal is actually lower than the preset data transmission rate threshold.

For example, the local system threshold in the redirection parameter threshold is -116dBm, the different system threshold in the redirection parameter threshold is -80dBm, the preset first time threshold is 320ms, and the data transmission rate threshold of the terminal is 1Mbps. The second time threshold is 320ms. At this time, the signal quality of the 4G network received by the terminal is -120dBm, the measured signal quality of the 3G network is -75dBm, the duration exceeds 320ms, the data transmission rate is 200Kbps, and the duration is also If it exceeds 320ms, then the base station determines that the received signal quality of the terminal is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the different system threshold in the redirection parameter threshold, and at the same time, the data transmission rate of the terminal is actually lower than the preset The data transfer rate threshold. For such a terminal, a redirection operation is required.

In the following, two specific application scenarios are adopted to further describe the foregoing embodiment in detail.

Referring to Figure 3, in this embodiment, the first specific process of inter-system redirection is as follows:

Step 300: the base station sends preset redirection parameter thresholds and data transmission rate thresholds to the terminal.

Wherein, the redirection parameter threshold includes a local system threshold and a different system threshold.

Step 310: The terminal judges that its own received signal quality is actually lower than the threshold of its own system in the redirection parameter threshold and actually higher than the different system threshold in the redirection parameter threshold.

Specifically, if step 310 is satisfied, then step 320 is performed; otherwise, step 350 is performed.

Step 320: The terminal determines that its own data transmission rate is actually lower than the preset data transmission rate threshold.

Specifically, if step 320 is satisfied, then step 330 is performed; otherwise, step 350 is performed.

Step 330: The terminal reports a redirection event report to the base station.

Specifically, when the received signal quality of the terminal is lower than the local system threshold in the preset redirection parameter threshold and is actually higher than the different system threshold in the redirection parameter threshold, and the data transmission rate of the terminal is lower than the preset data transmission When the rate threshold is reached, the terminal reports a redirection event report to the base station, and the redirection report records the received signal quality of the terminal, and the data transmission rate of the terminal or a comparison result between the data transmission rate of the terminal and the preset data transmission rate threshold.

Step 340: the base station sends a redirection instruction to the terminal according to the redirection report event, and the terminal accesses the redirection network.

Step 350: End the redirection process.

In this embodiment, the order of step 310 and step 320 can be changed, or they can be run in parallel.

Referring to Figure 4, in this embodiment, the second specific process of inter-system redirection is as follows:

Step 400: the base station sends preset redirection parameter thresholds and data transmission rate thresholds to the terminal.

Wherein, the redirection parameter threshold includes a local system threshold and a different system threshold.

Step 410: The terminal judges that the received signal quality of itself is actually lower than the local system threshold in the preset redirection parameter threshold and actually higher than the different system threshold in the redirection parameter threshold.

Specifically, if step 410 is satisfied, step 420 is performed; otherwise, step 450 is performed.

Step 420: The terminal reports the received signal quality of the terminal and the data transmission rate of the terminal to the base station.

Specifically, when the received signal quality of the terminal is lower than the local system threshold in the redirection parameter threshold and is actually higher than the different system threshold in the redirection parameter threshold, the terminal reports the received signal quality at this time to the base station, and reports this data transfer rate.

Step 430: the base station judges that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold.

Specifically, if step 430 is satisfied, then step 440 is performed; otherwise, step 450 is performed.

Step 440: the base station sends a redirection instruction to the terminal, and the terminal accesses the redirection network.

Step 450: End the redirection process.

Referring to Figure 5, the embodiment of the present invention also provides an overview flow of redirection between systems on the terminal side:

Step 500: The terminal receives preset redirection parameter thresholds and data transmission rate thresholds issued by the base station.

In this embodiment, when step 500 is executed, the terminal obtains the preset redirection parameter threshold issued by the base station through an RRC message.

Specifically, the terminal can obtain the preset redirection parameter threshold issued by the base station through various information elements in the RRC message.

When the terminal obtains the data transmission rate threshold, it can adopt but not limited to the following two methods:

The first way: the terminal obtains the preset data transmission rate threshold delivered by the base station through an RRC message.

Specifically, the terminal obtains the preset data transmission rate threshold issued by the base station through various information elements in the RRC message, and details are not described here.

The second way: the terminal obtains the preset data transmission rate threshold issued by the base station through a broadcast message.

Specifically, the terminal obtains the preset data transmission rate threshold issued by the base station through various information elements in the broadcast message.

Step 510: The terminal sends a redirection event report to the base station at least when it is determined that the local received signal quality is actually lower than the preset redirection parameter threshold of its own system threshold and is actually higher than the redirection parameter threshold of a different system threshold. The data transmission rate correlation information of the terminal is further recorded in the directional event report.

In the embodiment of the present invention, the terminal sends a redirection event report to the base station through a measurement message.

Specifically, the terminal reports the redirection event report to the base station through various information elements in the measurement message. For example, the redirection event report may be reported through an existing cell; the redirection event report may also be reported through a new cell, or the redirection event report may be reported through a reserved cell.

In the embodiment of the present invention, when performing step 510, the following two methods may be adopted but not limited to:

The first method: the terminal compares the local received signal quality with the redirection parameter threshold, and determines that the local received signal quality is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the foreign system in the redirection parameter threshold When the threshold is reached, the received signal quality of the terminal is recorded in the redirection event report,

The terminal further compares the local data transmission rate with the preset data transmission rate threshold, and when it determines that the local data transmission rate is actually lower than the preset data transmission rate threshold, records the terminal's data transmission rate or the comparison result in the redirection incident report;

A redirection event report is then sent to the base station.

For example, the signal quality of the local 4G network received by the terminal is -120dBm, and the measured signal quality of the 3G network is -75dBm. The threshold is -80dBm. At this time, the received signal quality of the terminal is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the different system threshold in the preset redirection parameter threshold, and the received signal quality of the terminal is -120dBm and The measured signal quality of the 3G network -75dBm is recorded in the redirection report event. At the same time, if the data transmission rate of the terminal is 500Kbps, and the preset data transmission rate threshold is 1Mbps, then the terminal will transmit data at a rate lower than the preset The comparison result of the data transmission rate threshold is also recorded in the redirection report event, or the current data transmission rate of 500 Kbps may be recorded in the redirection report event, and at this time, a redirection event report is sent to the base station.

The second method: the terminal compares the local received signal quality with the redirection parameter threshold, and determines that the local received signal quality is actually lower than the local system threshold in the redirection parameter threshold and actually higher than the foreign system in the redirection parameter threshold When the threshold is reached, record the received signal quality of the terminal in the redirection event report, and further record the local data transmission rate in the redirection report;

A redirection event report is then sent to the base station.

For example, the signal quality received by the terminal from the local 4G network is -120dBm, and the measured signal quality of the 3G network is -75dBm. is -80dBm, at this time, the received signal quality of the terminal is actually lower than the threshold of the system in the preset redirection parameter threshold and actually higher than the threshold of the different system in the redirection parameter threshold, and the received signal quality of the terminal is -120dBm And the measured signal quality of the 3G network -75dBm is recorded in the redirection report event. Further, the data transmission rate of the terminal is further recorded in the redirection report, assuming it is 500Kbps. At this time, a redirection event report is sent to the base station.

Step 520: The terminal receives the redirection instruction issued by the base station, and starts to execute the redirection process, wherein the redirection instruction is determined by the base station according to the redirection report that the received signal quality of the terminal is actually lower than the threshold of the system in the redirection parameter threshold and It is delivered when the actual data transmission rate is higher than the different system threshold in the redirection parameter threshold and the data transmission rate is actually lower than the preset data transmission rate threshold.

In the embodiment of the present invention, when executing step 520, the terminal determines that the local received signal quality is lower than the local system threshold in the redirection parameter threshold and greater than the different system threshold in the redirection parameter threshold, and the maintenance time exceeds the preset second threshold. When a time threshold is reached, it is determined that the local received signal quality is actually lower than the redirection parameter threshold;

For example, the local system threshold in the redirection parameter threshold is -116dBm, the different system threshold in the redirection parameter threshold is -80dBm, and the preset first time threshold is 320ms. At this time, the local 4G network received by the terminal The signal quality is -120dBm, the measured signal quality of the 3G network is -75dBm, and the duration exceeds 320ms, then it can be determined that the local received signal quality is actually lower than the redirection parameter threshold.

When the terminal determines that the local data transmission rate is lower than the preset data transmission rate threshold and the maintenance time exceeds the preset second time threshold, it determines that the local data transmission rate is actually lower than the preset data transmission rate threshold.

For example, the data transmission rate threshold of the terminal is 1Mbps, and the preset second time threshold is 320ms. At this time, the data transmission rate of the terminal is 200Kbps, and the duration exceeds 320ms, then it is determined that the local data transmission rate is actually lower than Preset data transfer rate threshold.
