Description

Method and device for redirecting between systems

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for inter-system redirection.

Background

The continuous evolution of the mobile communication technology not only improves the communication capacity of the wireless system, but also brings beneficial effects to the use of the terminal. However, with the explosive increase of data traffic in recent years, service personnel have to upgrade the network to meet the requirement of the terminal on the data traffic, and thus, the problem of multiple networks such as 2G, 3G, 4G and the like needs to be faced at the same time.

2G and 3G networks are constructed for a long time, the coverage is perfect, and the coverage of the 4G network which just starts is relatively poor. And in data transmission rate, the 4G network is higher than the 3G network, and the 3G network is higher than the 2G network. In order to ensure the use efficiency of the terminal, on one hand, data service should be carried by the high-speed network as much as possible, and on the other hand, when no suitable adjacent cell exists in the high-speed network and the signal quality of the serving cell is poor, the inter-system redirection to the low-speed network with more perfect coverage can be initiated.

Referring to fig. 1, a specific process of inter-system redirection in the prior art is as follows:

step 100: the base station issues parameter configuration information for inter-system redirection to the terminal through a Radio Resource Control (RRC) message.

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

In executing step 110, if yes, step 120 is executed, otherwise, the redirection procedure is ended.

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

Specifically, the event report may be an inter-system measurement event report or a blind redirection event report.

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

However, in the prior art, the quality of service of the terminal cannot be guaranteed to the maximum extent by only determining whether to perform the inter-system redirection operation according to the quality of the received signal of the terminal.

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

Detailed Description

In order to reduce the load of a low-speed network and improve the service quality of a terminal, the embodiment of the invention provides a method for redirecting among systems, which comprises the following steps: and sending a redirection instruction to the terminal when the received signal of the terminal is actually 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 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 the data transmission rate associated information of the terminal; and the terminal receives the redirection instruction issued by the base station and starts to execute the redirection flow.

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

Referring to fig. 2, in the embodiment of the present invention, an overview flow of inter-system redirection at the network side is as follows:

step 200: the base station sends a preset redirection parameter threshold and a data transmission rate threshold to the terminal; wherein, the redirection parameter threshold comprises the threshold of the system and the threshold of the different system.

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 a preset redirection parameter threshold to the terminal through multiple cells in the RRC message.

For example, a preset redirection parameter threshold may be sent to the terminal by sending an existing cell to the terminal; a preset redirection parameter threshold can also be sent to the terminal through the newly added cell; and sending a preset redirection parameter threshold to the terminal through the reserved cell.

When the base station sends the preset data transmission rate threshold to the terminal, the following two methods may be adopted, but not limited to:

the first mode is as follows: and the base station sends a preset data transmission rate threshold to the terminal through an RRC message.

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

for example, a preset data transmission rate threshold may be sent to the terminal through an existing cell; a preset data transmission rate threshold can also be sent to the terminal through the newly added cell; the preset data transmission rate threshold can also be sent to the terminal through the reserved cell.

The second mode is as follows: and the base station sends a preset data transmission rate threshold to the terminal through a broadcast message.

Specifically, the base station sends a preset data transmission rate threshold to the terminal through a plurality of cells in the broadcast message.

For example, a preset data transmission rate threshold may be sent to the terminal through an existing cell in the broadcast message; a preset data transmission rate threshold can also be sent to the terminal through the newly added cell; the preset data transmission rate threshold can also be sent to the terminal through the reserved cell.

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

The broadcast message may be a Master Information Block (MIB) or a System Information Block (SIBs).

The RRCConnectionReconfiguration message is specifically described below as an example. In The3rd generation partnership project (3 GPP) specification, The abstract syntax notation (ASN 1) data format of The RRCConnectionReconfiguration message is as follows:

therefore, the base station can send the preset redirection parameter threshold and the data transmission rate threshold to the terminal through the reserved cells at any positions of the message, such as spare 1-spare 7; or may send the preset redirection parameter threshold and data transmission rate threshold to the terminal through the existing cells such as "rrcConnectionReconfiguration-r 8" or "rrcConnectionReconfiguration-r 8-IEs"; and a preset redirection parameter threshold and a data transmission rate threshold can be sent to the terminal through a newly added cell derived on the basis of the original 3GPP specification.

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

In the embodiment of the 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 multiple cells in the measurement message. For example, a redirection event report may be reported through an existing cell; the redirection event report can be reported by a newly added cell and can also be reported by a reserved cell.

The following takes the MeasurementReport message as an example to specifically describe. In the 3GPP specification, the ASN1 data format of the MeasurementReport message is as follows:

therefore, the terminal can report the redirection report event through reserved cells at any position such as spark 1-spark 7 in the MeasurementReport; the redirection report event can also be reported by the existing cells such as 'measurementReport-r 8' or 'measurementReport-r 8-IEs'; and a redirection report event can be reported by a newly added cell derived on the basis of the original 3GPP specification.

Step 220: and the base station determines that the quality of the received signal 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 according to the redirection event report, and 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 transmits a redirection instruction to the terminal.

In the embodiment of the present invention, when step 220 is executed, the following two manners may be adopted, but not limited to:

the first mode is as follows: when the base station determines that the quality of the received signal of the terminal is recorded in the redirection event report, the base station determines that the quality of the received signal of the terminal is actually lower than a local system threshold in the redirection parameter threshold and is actually higher than a different system threshold in the redirection parameter threshold;

when determining that the data transmission rate of the terminal is recorded in the redirection event report or a comparison result of the data transmission rate of the terminal and a preset data transmission rate threshold is recorded, determining that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold;

and then, issuing a redirection instruction to the terminal.

Of course, in the first manner, the base station may also determine that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold when the redirection event report is recorded with 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 is recorded; and when the received signal quality of the terminal is recorded in the redirection event report, determining that the received signal quality of the terminal is actually 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. Or, when the base station determines that the received signal quality of the terminal is recorded in the redirection event report, it 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 inter-system threshold in the redirection parameter threshold; and meanwhile, when determining that the data transmission rate of the terminal is recorded in the redirection event report or the comparison result of the data transmission rate of the terminal and a preset data transmission rate threshold is recorded, determining that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold.

That is, the execution sequence of the two steps is not strictly limited, and is not described in detail herein.

When the base station determines that the quality of the received signal of the terminal is recorded in the redirection event report, specifically, when the terminal determines that the quality of the received signal of the terminal is actually lower than a local system threshold in the redirection parameter threshold and is actually higher than a different system threshold in the redirection parameter threshold, the quality of the received signal at the moment 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, specifically, when the terminal determines that the data transmission rate of the terminal is lower than the preset data transmission rate threshold, the data transmission rate at the moment is recorded in the redirection report or the comparison result between the data transmission rate and the preset data transmission rate threshold is recorded in the redirection report.

For example, the signal quality of the 4G network signal received by the terminal is-120 dBm, the measured signal quality of the 3G network is-75 dBm, the local system threshold of the redirection parameter threshold is-116 dBm, and the inter-system threshold of the redirection parameter threshold is-80 dBm, at this time, the received signal quality of the terminal is actually lower than the local system threshold of the redirection parameter threshold and is actually higher than the inter-system threshold of the preset redirection parameter threshold, the received signal quality of the terminal is-120 dBm and the measured signal quality of the 3G network is recorded in the redirection report event, and meanwhile, if the data transmission rate of the terminal is 500Kbps and the preset data transmission rate threshold is 1Mbps, the terminal records the comparison result that the data transmission rate is lower than the preset data transmission rate threshold in the redirection report event, the data transmission rate 500Kbps at this time can also be recorded in the redirection report event. At this time, the base station receives the redirection report and then issues a redirection instruction to the terminal.

The second mode is as follows: when the base station determines that the quality of the received signal of the terminal is recorded in the redirection event report, the base station determines that the quality of the received signal of the terminal is actually lower than a local system threshold in the redirection parameter threshold and is actually higher than a different system threshold in the redirection parameter threshold;

comparing the data transmission rate of the terminal with a preset data transmission rate threshold according to the data transmission rate of the terminal recorded in the redirection event report, and determining that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold according to a comparison result;

and then, issuing a redirection instruction to the terminal.

For example, the signal quality of the 4G network received by the terminal is-120 dBm, the measured signal quality of the 3G network is-75 dBm, the local system threshold in the redirection parameter threshold is-116 dBm, and the inter-system threshold in the redirection parameter threshold is-80 dBm, at this time, the received signal quality of the terminal is actually lower than the local system threshold in the preset redirection parameter threshold and is actually higher than the inter-system threshold in the redirection parameter threshold, the received signal quality of the terminal is-120 dBm and the measured signal quality of the 3G network is-75 dBm are recorded in a redirection report event, further, the data transmission rate of the terminal is recorded in a redirection report, and if it is 500Kbps, then, after receiving the redirection report, the base station compares the transmission rate of the terminal with the preset data transmission rate threshold, assuming that the preset data transmission rate threshold is 1Mbps, the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold, and at this time, the base station issues a redirection instruction to the terminal.

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

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

the first mode is as follows: and the base station receives the data transmission rate of the terminal or the comparison result of the data transmission rate of the terminal and a preset data transmission rate threshold recorded in the redirection event report, and directly determines that the data transmission rate of the terminal is actually lower than the preset 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 maintaining time exceeds a preset second time threshold.

For example, if the data transmission rate threshold of the terminal recorded in the redirection report received by the base station is 1Mbps, it may be directly determined that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold.

For another example, if the base station receives a 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 may directly determine that the data transmission rate of the terminal is actually lower than the preset data transmission rate threshold according to the < in the comparison record.

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

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

The above embodiments are described in further detail below using two specific application scenarios.

Referring to fig. 3, in the present embodiment, a first specific flow of inter-system redirection is as follows:

step 300: and the base station sends a preset redirection parameter threshold and a data transmission rate threshold to the terminal.

Wherein, the redirection parameter threshold comprises the threshold of the system and the threshold of the different system.

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

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

Step 320: and the terminal judges that the data transmission rate of the terminal is actually lower than a preset data transmission rate threshold.

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

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

Specifically, when the quality of the received signal of the terminal is lower than the local system threshold in the preset redirection parameter threshold and actually higher than the inter-system threshold in the redirection parameter threshold, and the data transmission rate of the terminal is lower than the preset data transmission rate threshold, the terminal reports a redirection event report to the base station, where the redirection report records the quality of the received signal of the terminal, and the data transmission rate of the terminal or the 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 a redirection network.

Step 350: the redirection flow is ended.

In this embodiment, the sequence of step 310 and step 320 may be changed or may be parallel.

Referring to fig. 4, in the present embodiment, a second specific flow of inter-system redirection is as follows:

step 400: and the base station sends a preset redirection parameter threshold and a data transmission rate threshold to the terminal.

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

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

Step 420: and 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 quality of the received signal of the terminal is lower than the local system threshold in the redirection parameter threshold and actually higher than the different system threshold in the redirection parameter threshold, the terminal reports the quality of the received signal at the moment to the base station, and reports the data transmission rate at the moment.

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

Specifically, if step 430 is satisfied, step 440 is executed, otherwise, step 450 is executed.

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

Step 450: the redirection flow is ended.

Referring to fig. 5, an overview flow of the terminal-side intersystem redirection is further provided in the embodiment of the present invention:

step 500: and the terminal receives a preset redirection parameter threshold and a data transmission rate threshold which are issued by the base station.

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

Specifically, the terminal may obtain the preset redirection parameter threshold issued by the base station through multiple cells in the RRC message.

When the terminal acquires the data transmission rate threshold, the following two methods can be adopted, but not limited to:

the first mode is as follows: the terminal acquires a preset data transmission rate threshold issued by the base station through the RRC message.

Specifically, the terminal obtains the preset data transmission rate threshold issued by the base station through multiple cells in the RRC message, which is not described herein again.

The second mode is as follows: the terminal acquires a preset data transmission rate threshold issued by the base station through the broadcast message.

Specifically, the terminal obtains a preset data transmission rate threshold issued by the base station through multiple cells in the broadcast message.

Step 510: the terminal at least determines that the local received signal quality is actually 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 sends a redirection event report to the base station, wherein the redirection event report further records the data transmission rate associated information of the terminal.

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

Specifically, the terminal reports the redirection event report to the base station through various cells in the measurement message. For example, a redirection event report may be reported through an existing cell; the redirection event report can be reported by a newly added cell and can also be reported by a reserved cell.

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

the first method comprises the following steps: the terminal compares the local received signal quality with the redirection parameter threshold, when the local received signal quality is actually 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 received signal quality of the terminal is recorded in a redirection event report,

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

For example, the terminal receives a signal quality of a local 4G network of-120 dBm, a measured signal quality of a 3G network of-75 dBm, a local system threshold of the redirection parameter threshold of-116 dBm, and a heterogeneous system threshold of the redirection parameter threshold of-80 dBm, at which time, the terminal received signal quality is actually lower than the local system threshold of the redirection parameter threshold and is actually higher than the heterogeneous system threshold of the preset redirection parameter threshold, records the terminal received signal quality of-120 dBm and the measured signal quality of-75 dBm of the 3G network in a redirection report event, and simultaneously, if the terminal has a data transmission rate of 500Kbps and the preset data transmission rate threshold of 1Mbps, the terminal records a comparison result that the data transmission rate is lower than the preset data transmission rate threshold in the redirection report event, the data transmission rate 500Kbps at this time may also be recorded in the redirection report event, at which time the redirection event report is transmitted to the base station.

The second method comprises the following steps: the terminal compares the local received signal quality with the redirection parameter threshold, records the received signal quality of the terminal in a redirection event report when the local received signal quality is actually 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, and further records 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 of a local 4G network received by the terminal is-120 dBm, the measured signal quality of the 3G network is-75 dBm, the local system threshold in the redirection parameter threshold is-116 dBm, and the inter-system threshold in the redirection parameter threshold is-80 dBm, at this time, the received signal quality of the terminal is actually lower than the local system threshold in the preset redirection parameter threshold and is actually higher than the inter-system threshold in the redirection parameter threshold, the received signal quality of the terminal is-120 dBm and the measured signal quality of the 3G network is-75 dBm are recorded in a redirection report event, further, the data transmission rate of the terminal is further recorded in the redirection report, and if the data transmission rate is 500Kbps, at this time, a redirection event report is sent to the base station.

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

In the embodiment of the present invention, when step 520 is executed, the terminal determines that the local received signal quality is lower than the local system threshold in the redirection parameter threshold and is greater than the inter-system threshold in the redirection parameter threshold, and when the holding time exceeds the preset first time threshold, determines that the local received signal quality is actually lower than the redirection parameter threshold;

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

And the terminal determines that the local data transmission rate is lower than a preset data transmission rate threshold, and determines that the local data transmission rate is actually lower than the preset data transmission rate threshold when the maintaining time exceeds a preset second time threshold.

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