Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for measuring and reporting cell signal quality and controlling cell handover.
Background
Time Division long term evolution (TD-LTE) is a subsequent evolution technology of international 3G standard Time Division synchronous Code Division Multiple Access (TD-SCDMA) with independent intellectual property rights in China (TD-SCDMA is hereinafter abbreviated as TD), a TD network has the advantages of high-quality coverage, sufficient station addresses, faithful user groups and the like, existing TD network equipment can coexist with the TD-LTE system for a long Time in order to protect investment, the coverage can be expanded by a common network of the TD and the TD-LTE, the load is balanced, and the investment cost is reduced.
The intersystem handover of TD and TD-LTE is an indispensable part of the mobility management of the common network. Due to the fact that the throughput and the peak rate of TD-LTE are higher than those of a TD system, better service experience can be brought to users, and the area covered by TD-LTE and TD should ensure that User Equipment (UE) is switched to TD-LTE preferentially. Meanwhile, different UEs are classified into different classes according to the needs of the operator when signing up for a network, and in principle, a high-class user should enjoy service experience brought by a high-priority network. That is, a high-ranked user should have the right to preferentially select a high-priority system at the time of handover.
However, in the current system, the same handover policy is adopted for all users, and no distinction is made for user classes, so that users of high class cannot enjoy the due service.
The coverage of the existing TD network is already complete, and the coverage of the TD-LTE network is also expanded and gradually improved. In the future, operators may operate multiple systems simultaneously for traffic sharing. In order to ensure that a user can switch between systems more quickly and better on the basis of not influencing the existing services, the TD-LTE system must be compatible with the existing TD network, i.e. seamless roaming, switching and reselection between TD and TD-LTE must be realized. The purpose of intersystem roaming, handover and reselection is to provide uninterrupted, timely and better quality of service for the user's communication between different systems.
In the current system, when the UE is in a connected state, the network implements mobility management for the UE through a handover procedure. The current switching mode consists of two parts, namely a measurement process and a switching process, wherein a terminal carries out measurement, and a network carries out switching judgment and execution. In order to make the UE auxiliary network make switching judgment, the source network configures measurement for the UE, so that the UE reports the channel quality of the serving cell and the adjacent cell before switching, and the network side judges switching according to the UE measurement result and executes the switching.
The measurement process is divided into two parts of measurement starting and measurement reporting, and the following steps are carried out:
a. starting measurement:
the network issues measurement configuration through System Information Broadcast (SIB) or Radio Resource Control (RRC) message, wherein the measurement configuration includes measurement related information such as measurement object, measurement quantity, report quantity, event trigger criteria and the like of the UE, and the UE performs measurement and reports according to the information in the measurement configuration.
b. And (3) measurement and reporting:
measurement reporting criteria of the TD system:
event triggers (last or periodic reporting) define the following events (events):
3A event: the quality of the frequency point of the currently used Universal Terrestrial Radio Access Network (UTRAN) system is less than a certain threshold and the frequency point quality of the different system cell is greater than a certain threshold.
And reporting the UE Measurement result by a Measurement Report (Measurement Report) signaling mode.
In the LTE system, the following 2 measurement reporting events (B1/B2) are defined:
event B1: the quality of the adjacent cell is higher than a certain threshold;
event B2: the serving cell quality is below an absolute threshold of 1 and the neighbor cell quality is above another absolute threshold of 2.

Detailed Description
The embodiment of the invention provides a method and a device for measuring and reporting cell signal quality, which are used for reporting a measurement result of the cell signal quality according to the priority of UE (user equipment), so that the UE with high priority can report the measurement result preferentially, and the UE with high priority is switched to a network system with high priority preferentially.
The embodiment of the invention provides a cell switching control method and a cell switching control device, which are used for realizing cell switching control on UE according to the priority of the UE, so that the UE with high priority can be switched to a network system with high priority preferentially.
In the embodiment of the invention, when the reporting judgment is carried out on the UE with high priority, the UE is allowed to carry out weighting or deviation on each threshold parameter, the judgment criterion is relaxed, and the trigger time of the criterion is properly reduced, so that the measurement report is easier to trigger and report, and the UE with high priority can be switched to a network with high priority, such as a TD-LTE network, more timely, quickly and preferentially.
The technical solution provided by the embodiment of the present invention is explained below with reference to the accompanying drawings.
Referring to fig. 1, at a UE side, a method for measuring and reporting cell signal quality provided in an embodiment of the present invention includes:
s101, User Equipment (UE) receives measurement configuration information which is sent by a network side and used for cell switching, wherein the measurement configuration information comprises a reporting condition of a measurement result;
s102, modifying the reporting condition included in the measurement configuration information by the UE according to a preset modification mode corresponding to the priority of the UE to obtain the modified reporting condition;
s103, when the modified reporting condition is met, the UE reports the measurement result obtained by measuring the signal quality of the cell according to the measurement configuration information to the network side.
Preferably, the modifying, by the UE, the reporting condition included in the measurement configuration information according to a preset modifying manner corresponding to the priority of the UE, to obtain a modified reporting condition, including:
UE obtains offset;
the UE modifies parameters in reporting conditions included in the measurement configuration information by using the offset according to a preset modification mode corresponding to the priority of the UE;
and the UE generates the modified reporting condition by using the modified parameters.
Preferably, the UE obtains an offset, including:
UE acquires offset from local; or,
the UE obtains the offset from the high-layer signaling sent by the network side.
Preferably, the higher layer signaling is a system message or a measurement control message.
Preferably, the method further comprises:
and the UE sends the priority information of the UE to the network side.
Preferably, the UE sends the priority information of the UE to the network side, including:
the UE requests an RRC Connection Request message through radio resource control Connection and sends the priority information of the UE to a network side; or,
the UE completes RRC Connection Setup Complete message through radio resource control Connection, and sends the priority information of the UE to the network side; or,
and the UE sends the priority information of the UE to the network side through a Measurement Report.
Preferably, the reporting condition included in the measurement configuration information includes:
the following formula one and formula two are satisfied simultaneously, and the specific time Timetotrigger lasts:
the formula I is as follows: qUsed≤TUsed-H3a/2；
The formula II is as follows: mOtherRAT+CIOOtherRAT≥TOtherRAT+H3a/2；
Wherein Q isUsedIs the cell signal quality, T, of the UTRAN systemUsedIs the absolute quality threshold, H, of the UTRAN system3aIs a hysteresis parameter, MOtherRATIs a measure of the signal quality of a system cell outside the UTRAN; CIOOtherRATIs the personality offset of the system cell outside the UTRAN; t isOtherRATIs the absolute threshold of system cells outside the UTRAN;
the reporting condition included in the measurement configuration information, that is, the reporting condition configured in the measurement configuration information sent by the network side to the UE in the prior art.
The UE modifies parameters in reporting conditions included in the measurement configuration information by using the offset according to a preset modification mode corresponding to the priority of the UE, and the modification mode comprises the following steps:
the UE modifies T as followsUsed、H3a、TOtherRAT、CIOOtherRAT、MOtherRATAnd/or the Timetotrigger modifies:
TUsed＝TUsed+offset；
H3a＝H3a-offset；
TOtherRAT＝TOtherRAT-offset；
CIOOtherRAT＝CIOOtherRAT+offset；
MOtherRAT＝MOtherRAT+offset；
Timetotrigger＝Timetotrigger-Toffset；
wherein offset and ToffsetIs an offset.
In the embodiment of the present invention, only one or more of the parameters may be modified, and when a parameter needs to be modified, a modification method corresponding to the parameter may be adopted for modification.
In the embodiment of the present invention, different offsets may be set for different parameters, for example, TUsedAnd H3aThe corresponding offset amounts differ in value. The same offset may also be set for different parameters, e.g. TUsedAnd H3aThe corresponding offset values are the same.
In addition, in the embodiment of the present invention, the offset values set for UEs of different priorities are different. For example, for a high priority UE, the value of offset is greater than 0, ToffsetA value of greater than 0; for low priority (or normal) UEs, the offset has a value of 0 or less than 0, ToffsetIs 0 or less than 0.
That is to say, relative to the parameter criteria configured by the network, when the UE with high priority performs event criteria judgment, the UE is easier to trigger a 3A event, which is helpful for the network to switch the UE of this level to the LTE system cell in time. And the common UE can not perform offset according to the traditional event triggering criterion so as to ensure that the common user can also achieve seamless coverage.
After receiving the measurement report reported by the UE, the network side can make a switching decision, and if the UE is a high-priority user, the network side also makes a certain offset for the switching decision criterion so as to ensure that the UE can be switched into a high-priority network in time. In the embodiment of the invention, an identifier is set for the UE to identify whether the UE is the UE with high priority or not.
Correspondingly, on the network side, referring to fig. 2, a cell handover control method provided in an embodiment of the present invention includes the steps of:
s201, a radio network controller RNC sends measurement configuration information for cell switching to user equipment UE;
s202, the RNC receives the measurement result reported by the UE and acquires the priority of the UE;
s203, the RNC carries out cell switching judgment on the UE according to the measurement result reported by the UE and the priority of the UE.
Preferably, the acquiring, by the RNC, the priority of the UE includes:
the RNC requests RRC Connection Request information through radio resource control Connection to acquire the priority information of the UE; or,
the RNC establishes and completes RRC Connection Setup Complete message through radio resource control Connection, and acquires the priority information of the UE; or,
the RNC acquires the priority information of the UE through a Measurement Report; or,
and the RNC acquires the priority information of the UE through Iu interface information sent by a core network.
Preferably, the RNC makes a cell handover decision for the UE according to the measurement result reported by the UE and the priority of the UE, including:
the RNC judges whether the preset cell switching criterion needs to be modified or not according to the priority of the UE, if so, the preset cell switching criterion is modified by using the preset offset, and the modified cell switching criterion is used for carrying out cell switching judgment on the UE; otherwise, the cell switching judgment is carried out on the UE by utilizing the preset cell switching criterion.
For example, the following formula three and formula four are cell handover decision formulas after the RNC receives the measurement report of the UE in the prior art:
the formula III is as follows: qs＜ScellTh；
The formula four is as follows: t isother＞AddOtherTH；
Wherein Q issIndicating the quality of measurements of the UTRAN serving cell; ScellTh represents the UTRAN serving cell absolute pilot decision threshold; t isotherRepresents the measurement quality of a system cell other than UTRAN; AddOtherTH denotes an absolute pilot decision threshold of a system cell other than UTRAN.
In the prior art, when the formula three and the formula four are simultaneously satisfied, the RNC may perform cell handover according to the measurement report of the UE.
In the embodiment of the invention, after receiving the measurement report reported by the UE, the RNC finds that if the UE is the high-priority UE, the RNC carries out cell switching judgment on the UE according to the following formula five and formula six:
the formula five is as follows: qs＜ScellTh+offset；
Formula six: t isother＞AddOtherTH-offset；
Although offset also represents an offset amount, the offset amount in each formula may be a different value or the same value in different formulas, for example, the value may be 0 to 16 dB.
In this way, the handover decision criteria for the high priority UE is relaxed, so that the high priority UE is handed over to the high priority system in time.
In the embodiment of the present invention, how the UE obtains the offset values such as offset and Toffset may consider adopting two ways: one is to bind these offset information with the priority when the UE signs up for the network; for example, for a high priority UE, offset is a value greater than 0dB, and Toffset is a value greater than 0; for low-priority UE (or ordinary UE), offset is a value of 0dB or less than 0dB, and Toffset is a value of 0 or less than 0; another way is an over-high layer signaling configuration, which may be configured to the UE through system information or measurement control message. Taking the measurement control message as an example, the specific configuration may be as shown in table one below:
