Description

Terminal frequency band processing method, device, equipment and medium

Technical Field

The present invention relates to the field of data services, and in particular, to a method, an apparatus, a device, and a computer storage medium for processing a terminal frequency band.

Background

When the network side makes various event decisions or executes various algorithms, the network side can make a practical optimal decision according to the wireless support capability of the user terminal. The wireless support capability includes information such as wireless frequency band information supported by the user terminal and whether the user terminal supports carrier aggregation. For example, the user terminal supports the frequency band 34, and the network side issues measurement control of the user terminal on the frequency band 34 in a Radio Resource Control (RRC) connection reconfiguration message, so as to facilitate redirection or switching of the user terminal in a later connection state. If the user terminal does not support the frequency band 34, the network side will not issue measurement control on the frequency band 34.

In a Long Term Evolution (LTE) user terminal of a certain brand in an existing network, the user terminal reports and supports certain frequency bands to a network side in an LTE Time Division Duplex (TDD) network environment. However, in some scenarios, the user terminal actually accesses a frequency band that is not reported to the network side. For example: some user terminals report frequency bands only supporting FDD Band 3; but actually the FDD Band8 Band can be accessed. When the user terminal initiates a service from an idle state (for example, call origination, internet access, etc.), a user context is established. At this time, the network node (MME) may issue an initial context request and inform the base station of the wireless support capability reported by the ue.

However, since the frequency band actually accessed by the user terminal is not in the supported frequency band information reported by the user terminal, the base station does not issue measurement control to the terminal, which may cause problems such as call drop, excessive RRC reestablishment times, or network disconnection of the user terminal.

Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

In some scenarios, since the user terminal accesses the supported frequency band that is not reported to the network side in the idle state, the network side does not issue a measurement control message to the user terminal when the user terminal initiates a service from the idle state. When the user terminal moves to a place with weak coverage of the current access cell, coverage-based handover cannot be initiated, which may cause the problems of user terminal offline and triggering RRC reestablishment, etc.

Based on this, embodiments of the present invention provide a method, an apparatus, a device, and a medium for processing a terminal frequency band, where when supported frequency band information reported by a user terminal does not include an actual access frequency band of the user terminal, frequency band measurement information in a measurement control message that is issued is determined by using the actual access frequency band and the supported frequency band information of the user terminal, so that measurement control on the actual access frequency band is issued to the user terminal under the condition that the actual access frequency band of the user terminal does not belong to the supported frequency band reported by the user terminal, and problems such as a dropped call and a large number of RRC reestablishments are solved.

The actual access frequency band is the frequency band information actually accessed by the user terminal in the current network. The supported frequency band information is frequency band list information supported by the user terminal reported to the network side by the user terminal, and comprises each supported frequency band of the user terminal reported to the network side by the user terminal.

First, a method for processing a terminal frequency band according to an embodiment of the present invention is described in detail with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a method for processing a terminal frequency band according to an embodiment of the present invention. As shown in fig. 1, a method 100 for processing a terminal frequency band in this embodiment includes the following steps:

s110, acquiring the actual access frequency band of the user terminal and the original support capability information of the user terminal.

In the embodiment of the present invention, when making various event decisions or executing various algorithms, the network side needs to know the capability of a User Equipment (UE) to make the most appropriate decision, so that the UE needs to report the support capability information of the UE. Because the wireless support capability of the UE is also related to the 3GPP protocol version, and based on the consideration that the cost of each UE and the support capability of each UE are different and have a large difference, the network side needs the UE to report the support capability of the UE, so that the network side can accurately know the wireless support capability of the UE.

When the UE is powered on, it will actively report its own support capability information, i.e. the original support capability information of the UE. The original support capability information of the UE includes information such as the support power of the UE, the radio frequency band information supported by the UE, whether the UE supports inter-band handover, and whether the UE supports carrier aggregation.

In order to reduce air interface signaling as much as possible, the base station sends the original support capability information of the UE to the MME, and the MME saves the original support capability information of the UE.

When the user terminal is switched from an idle state to a service state, the base station sends a wireless capability information indication message to the MME, the MME transmits the original support capability information of the UE to the base station through an initialization context setting request message of an S1AP interface, and the base station replies an initialization context setting response message.

In the embodiment of the invention, when the UE initiates a service from an idle state, the UE reports the actual access frequency band in the current network. In order to determine whether the actual access frequency band of the UE belongs to the supported frequency band information reported by the UE on the network side, the base station needs to obtain the original support capability information of the UE from the MME.

S120, it is determined that the supported frequency band information of the user terminal in the original supporting capability information does not include the actual access frequency band.

In the embodiment of the invention, after the base station acquires the actual access frequency band of the UE and the original supporting capability information of the UE, the actual access frequency band of the UE is compared with the supporting frequency band list of the UE in the original supporting capability information of the UE so as to judge whether the actual access frequency band of the UE belongs to the supporting frequency band reported by the UE.

If the supported frequency band list of the UE in the original supporting capability information of the UE comprises the actual access frequency band of the UE, the fact that the actual access frequency band of the UE is not abnormal at the moment is represented, and the base station issues a measurement control message to the UE according to the frequency band supported by the base station and the supported frequency band of the UE in the original supporting capability information of the UE.

If the supported frequency band list of the UE in the original support capability information of the UE does not include the actual access frequency band of the UE, it represents that the frequency band actually accessed by the UE is abnormal at this time.

S130, determining frequency point measurement information according to the actual access frequency band and the support frequency band information of the user terminal in the original support capability information.

In an embodiment of the present invention, step S130 includes the steps of:

In the embodiment of the present invention, when the UE initiates a service from an idle state, if the supported frequency band list of the UE in the original support capability information of the UE does not include the actual access frequency band of the UE, the actual access frequency band of the UE is recorded.

Firstly, the base station merges the recorded actual access frequency band and each supporting frequency band in the supporting frequency band list of the UE in the original supporting capability information of the UE to obtain a set A. And then, the base station determines the frequency point measurement information in the issued measurement control message by using the intersection of the set A and the frequency band set B supported by the base station.

As an example, a variable "actual access frequency band information" is set in the base station, and a value of the variable is determined according to a relationship between the actual access frequency band and a supported frequency band list of the UE in the original support capability information.

When the supported frequency band list of the UE in the original support capability information of the UE includes the actual access frequency band of the UE, "actual access frequency band information" is set to a null value. When the supported frequency band list of the UE in the original support capability information of the UE does not include the actual access frequency band of the UE, the "actual access frequency band information" is a specific numerical value of the actual access frequency band.

According to the frequency band value in the 'actual access frequency band information' and the union set of all the supported frequency bands in the supported frequency band list of the UE in the original supporting capability information of the UE, the frequency point measurement information can be determined.

S140, sending the measurement control message including the frequency point measurement information to the user terminal.

In an embodiment of the present invention, step S140 includes the steps of:

s1401, sending down an A2 event measurement threshold T comprising a first frequency point₁The first frequency point is the frequency point of the first current service cell of the user terminal, and the first frequency point belongs to the actual access frequency band.

Wherein, the A2 event of the first frequency point represents that the quality of the first current service cell is lower than T₁；T₁The preset measurement threshold T of the A2 event of the first frequency point₁', the T₁' preconfigured by the base station.

In the embodiment of the invention, the measurement object in the measurement control message issued by the base station comprises the first frequency point in the actual access frequency band of the UE, so that the problems of call drop, network disconnection and excessive RRC reconstruction times caused by the fact that the base station does not issue the measurement control message to the UE under the application scene that the actual access frequency band of the UE does not belong to the supporting frequency band list of the UE in the original supporting capability information of the UE are avoided.

In the embodiment of the invention, the base station sends the measurement control message notification to the UE through a measConfig cell carried by the RRC connection reconfiguration message. The measurement control message sent by the base station may include, in addition to the a2 event measurement threshold of the first frequency point, information such as a measurement identifier, a reporting mode, and related information of other measurement frequency points.

If the problem that the actual access frequency band does not belong to the supported frequency band information reported by the UE is solved at the terminal side, the user is not necessarily upgraded due to the large number of the UEs, and the influence is large. In addition, for some UEs that have already reached the end stage, the UE vendor will not release the version for upgrade. Therefore, the above-described problems cannot be solved completely at the terminal side.

The method for processing the terminal frequency band provided by the embodiment of the invention determines the information of the frequency point quantity by utilizing the union of the actual access frequency band of the UE and the supporting frequency band of the UE in the original supporting capacity information reported by the UE through the base station at the network side, thereby realizing the transmission of the measurement control information to the frequency point in the actual access frequency band. The problem that the actual access frequency band does not belong to the supported frequency band reported by the UE is solved on the network side, so that the problem is thoroughly solved.

In addition, the method for processing the terminal frequency band provided by the embodiment of the invention does not relate to modification of interface messages between network elements, has small influence on the current network, and does not need to consider the problem of adaptation between network elements of each device.

In some embodiments of the present invention, in a scenario that an actual access frequency band of a UE does not belong to a support frequency band of the UE in original support capability information reported by the UE, for a certain type of UE, if a base station initiates a support capability query message to the UE, the type of UE supports updating the original support capability message. That is, the current support capability message reported by the UE includes the actual access frequency band of the UE, so as to solve the problem that the base station does not issue the measurement control message to the UE.

Fig. 2 is a flowchart illustrating a processing method for a terminal frequency band according to another embodiment of the present invention. The same steps in fig. 2 as those in fig. 1 use the same numbers, and as shown in fig. 2, the method 200 for processing the terminal band is basically the same as the method 100 for processing the terminal band shown in fig. 1, except that step S130 in the method 200 for processing the terminal band specifically includes the following steps:

and S1301, sending supporting capacity query information to the user terminal so that the user terminal reports the current supporting capacity information of the user terminal.

S1302, receiving current support capability information of the user terminal.

In the embodiment of the invention, if the base station initiates the support capability query of the actual access frequency band network type, the UE responds to the support capability query message sent by the base station and reports the current support capability information of the UE. In a scenario that the actual access frequency band of the UE does not belong to the supported frequency band of the UE in the original support capability information, the base station can only obtain whether the UE supports updating the supported frequency band of the UE in the original support capability information by sending a support capability query message to the UE.

And the base station receives the current support capability information reported by the UE and judges whether the UE updates the original support capability information or not according to the support frequency band information of the UE in the received current support capability information of the UE.

S1303, determine whether the supported frequency band information of the user terminal in the current supported capability information includes an actual access frequency band.

In the embodiment of the present invention, if it is determined that the supported frequency band information of the user terminal in the current support capability information includes the actual access frequency band, step S1303-1 is performed; if it is determined that the supported frequency band information of the UE in the current support capability information does not include the actual access frequency band, the process proceeds to step S1303-2.

In the embodiment of the invention, for the first type of UE, the current support capability information reported by the UE is different from the original support capability information reported by the UE when the UE is started, namely, the UE updates the wireless support capability. For such UE, the updated supported frequency band information of the UE in the current supported capability information includes the supported frequency band information of the UE in the original supported capability information and the actual access frequency band.

For the second class of UEs, no update to the original support capability message is supported. That is, even if the base station sends the support capability query message to the UE, the support frequency band information of the UE in the current support capability message reported by the UE is the same as the support frequency band information of the UE in the original support capability message of the UE, and does not include the actual access frequency band of the UE.

S1303-1, determining the information of the measurement frequency point according to the actual access frequency band in the current support capability information and the support frequency band information of the user terminal in the original support capability information included in the current support capability information.

In the embodiment of the invention, for the first type of UE, the base station determines that the actual access frequency band of the UE belongs to the support frequency band of the UE in the updated current support capability message according to the updated current support capability information reported by the UE.

In the embodiment of the invention, the frequency point information needing to be measured is determined according to the actual access frequency band of the UE in the current supporting capability message and the supporting frequency band information of the UE in the original supporting capability information included in the current supporting capability information.

The method for processing the terminal frequency band provided by the embodiment of the invention can report the current supporting capability message supporting the actual access frequency band by initiating the supporting capability query message to the UE, thereby solving the problem that the base station does not issue the measurement control message to the UE when the actual access frequency band of the UE does not belong to the supporting frequency band information of the UE in the original supporting capability message, improving the processing speed and the processing efficiency, improving the user perception, avoiding the problem of call drop of the UE and reducing the times of RRC reconstruction.

S1303-2, according to the actual access frequency band and the supporting frequency band information of the user terminal in the original supporting capacity information, determining frequency point measurement information.

In the embodiment of the present invention, for the second type of UE, the supported frequency band information of the UE in the current supported capability message reported by the UE of this type is the same as the supported frequency band information of the user terminal in the original supported capability message, so that after the base station receives the current supported capability message reported by the UE, it can be determined that the supported frequency band information of the UE in the current supported capability message does not include the actual access frequency band of the UE.

In the embodiment of the invention, the base station can determine the frequency point measurement information included in the measurement control message sent to the UE according to the union of the actual access frequency band and each supported frequency band in the supported frequency band list of the UE in the original supporting capability message, thereby avoiding the problems of call drop, offline or more times of RRC reconstruction.

In the embodiment of the invention, after the base station issues the measurement control message comprising the actual access frequency band of the UE, the problems of call drop, offline or more times of RRC reconstruction and the like are avoided, but if the UE is always accessed to the frequency band within the range of the frequency band supported by the UE in the message with non-original support capability, a plurality of potential problems of call drop or offline and the like exist. To solve this problem, fig. 3 is a flowchart illustrating a processing method 300 for a terminal frequency band according to still another embodiment of the present invention. The same steps in fig. 3 as those in fig. 1 are denoted by the same reference numerals, and as shown in fig. 3, the processing method 300 of the terminal band is substantially the same as the processing method 100 of the terminal band shown in fig. 1, except that after step S1401, the processing method of the terminal band further includes the following steps:

s310, receiving the A2 event measurement report of the first frequency point, and sending down the A4 event measurement threshold T comprising the second frequency point₂And the second frequency point is the frequency point of the adjacent cell corresponding to the first current service cell, and belongs to the supporting frequency band information of the user terminal in the original supporting capacity information.

In the embodiment of the invention, the first frequency point of the current service cell of the UE belongs to the actual access frequency band, and as the UE is always in the frequency band within the range of the support frequency band in the UE in the non-original support capability message, a plurality of potential problems of call drop or offline and the like exist, an A2 event measurement threshold T comprising the first frequency point needs to be issued₁To enable the UE to monitor the quality of the current serving cell. Wherein the content of the first and second substances,the A2 event of the first frequency point represents that the quality of the first current service cell is lower than T₁。

In the embodiment of the invention, if the UE monitors that the quality of the current serving cell is lower than T₁Then report the a2 event measurement report for the first frequency point so that the base station can make a decision. After receiving the a2 event measurement report of the first frequency point, the base station may send an a4 event measurement threshold T including the second frequency point in order to allow the UE to access the UE supported frequency band in the original support capability message₂To the UE so that the UE monitors the quality of the neighbor cell of the current serving cell.

The triggering mode of the measurement report is divided into periodic triggering and event triggering, and when the measurement report condition is met, the UE fills the measurement result into a measurement report message and sends the measurement result to the base station.

Wherein, the A4 event of the second frequency point represents that the quality of the adjacent cell corresponding to the first current service cell is higher than T₂；T₂The preset measurement threshold T of the A4 event of the second frequency point₂', the T₂' preconfigured by the base station.

S320, receiving the a4 event measurement report of the second frequency point, so that the user equipment switches from the first current serving cell to the neighboring cell corresponding to the first current serving cell.

In the embodiment of the invention, when the UE monitors that the quality of the neighbor cell corresponding to the current serving cell is higher than T₂And reporting the A4 event measurement report of the second frequency point to the base station by the UE. And after receiving the A4 event measurement report of the second frequency point, the base station controls the UE to switch from the actual access frequency band to the supporting frequency band of the UE in the original supporting capability message reported by the UE.

Through steps S310 to S320, the UE is switched from the actual access frequency band to the supported frequency band of the UE in the original support capability message reported by the UE, that is, the UE is switched with different frequencies, thereby avoiding the problems of call drop or network disconnection caused by the UE being always in the actual access frequency band.

In some embodiments of the present invention, in order to further preferentially switch the UE from the actual access frequency band that does not belong to the supported frequency band of the UE in the original support capability message to the supported frequency band of the UE, a configuration may be newly added, that is, a measurement threshold for switching the actual access frequency band to the supported frequency band of the UE.

Specifically, the a2 event measurement threshold T of the first frequency point₁Higher than T₁', and the A4 event measurement threshold T of the second frequency bin₂Below T₂'. By adding the above setting, the UE can be switched to the frequency point in the supporting frequency band of the UE from the frequency point in the actual access frequency band at high priority. For T₁' and T₂The specific value range of the present invention is not specifically limited, and may be determined according to specific application scenarios.

In the embodiment of the present invention, for the measurement threshold under other conditions, for example, the same-frequency handover or inter-system handover occurring in the actual access frequency band or the support frequency band of the UE, may be performed according to the threshold configured in advance by the base station.

In some embodiments of the present invention, when the UE is switched from the idle state to the service state, through steps S110 to S140, the base station may issue a measurement control message including an actual access frequency band, so as to avoid the problems of dropped call, offline or excessive RRC reestablishment times. But also results in that under different service states (such as intra-station handover and inter-station handover) of the UE, the UE may be in a frequency band which does not belong to the range of the supported frequency band of the UE in the original support capability message.

Therefore, in some embodiments of the present invention, if the actual access frequency band of the UE does not belong to the supported frequency band of the UE in the original support capability message reported by the UE, after the UE switches from the idle state to the service state, that is, after step S140, if the UE performs inter-station handover, the base station will repeat S120 to S140 after the UE completes the inter-station handover.

In the embodiment of the invention, the inter-station switching comprises S1 interface switching and X2 interface switching. Wherein the S1 interface is an interface between the base station and the MME, and the X2 interface is an interface between the source base station and the target base station.

When the UE performs the X2 interface switching, the target base station acquires the original support capability message of the UE through the source base station. The original support capability message of the UE will be carried in the handover request message sent by the source base station to the target base station.

When the UE performs S1 interface switching, the target base station acquires the original support capability message of the UE through the MME. And the MME sends a switching request message to the target base station, wherein the switching request message carries the original support capability message of the UE.

In the embodiment of the invention, after the UE performs inter-station switching, the target base station judges whether the actual access frequency band belongs to the supporting frequency band information of the UE in the original supporting capability message of the UE according to the actual access frequency band reported by the UE and the supporting frequency band information of the UE in the original supporting capability message of the UE.

(1) If the UE is subjected to pilot frequency switching, namely the UE is switched from the supporting frequency band of the UE in the original supporting capability message which does not belong to the UE to the supporting frequency band of the UE in the original supporting capability message which belongs to the UE, namely the actual access frequency band of the UE after the UE completes the inter-station switching belongs to the supporting frequency band information of the UE in the original supporting capability message of the UE, the base station represents that the actual access frequency band of the UE is not abnormal, and the base station sends a measurement control message to the user terminal.

(2) If the UE is switched in the same frequency, the actual access frequency band after the UE completes the inter-station switching does not belong to the UE support frequency band information in the original support capability message of the UE. After determining that the supported frequency band information of the ue in the original supporting capability information does not include the actual access frequency band, i.e. after repeating step S120, step S130 and step S140 are repeated.

In order to switch the UE from the actual access frequency band to the supported frequency band of the UE in the original support capability message reported by the UE, in some embodiments of the present invention, in a scenario where the UE is in inter-station handover, after step S140, step S310 to step S320 are further included.

Further, in order to enable the UE to preferentially access the supported frequency band of the UE in the original support capability message of the UE, the preset measurement threshold T of the a2 event of the actual access frequency band may be increased according to a specific application scenario₁'and reducing the preset measurement threshold T of the A4 event of the UE's supported band in the UE original support capability message₂’。

In some embodiments of the present invention, if the actual access frequency band of the UE does not belong to the supported frequency band of the UE in the original support capability message reported by the UE, after the UE is switched from the idle state to the service state, that is, after step S140, if the UE performs the intra-station handover, the base station repeats S120 to S140 after the UE completes the intra-station handover.

In the embodiment of the invention, when the UE performs the intra-station switching, the base station stores the supporting frequency band of the UE in the original supporting capability message of the UE. That is, the base station itself may provide the original support capability information of the user terminal.

In the embodiment of the invention, after the UE completes the intra-station switching, the base station judges whether the actual access frequency band reported by the UE belongs to the supporting frequency band of the UE in the original supporting capability message of the UE.

(1) If the UE performs the same-frequency handover, the actual access frequency band after the handover in the UE station does not belong to the UE support frequency band information in the original support capability message of the UE, that is, after repeating step S120, the base station repeats step S130 and step S140 to implement issuing the measurement control message to the UE.

Similarly, in order to switch the UE from the actual access frequency band to the supported frequency band of the UE in the original support capability message reported by the UE, in some embodiments of the present invention, in a scenario where the UE is in intra-station handover, after step S140, steps S310 to S320 are further included.

Further, in order to enable the UE to preferentially access the supported frequency band of the UE in the original support capability message of the UE, the measurement threshold T of the a2 event of the actual access frequency band may be increased according to a specific application scenario₁And reducing the measurement threshold T of the A4 event of the UE's supported frequency band in the UE original support capability message₂。

(2) If the UE is subjected to pilot frequency switching, after the UE completes intra-station switching, the actual access frequency band of the UE belongs to the UE supporting frequency band information in the original supporting capability message of the UE, the UE access frequency band is not abnormal, and the base station issues a measurement control message comprising the UE supporting frequency band to the user terminal.

In the embodiment of the present invention, in an application scenario of intra-site handover, a base station may store measurement parameters of frequency points in a supported frequency band of a UE, for example, a measurement threshold T of a second frequency point a4 event in the supported frequency band of the UE₂Pre-configured for the frequency point than the base stationSet threshold T₂' lower. Under the above situation, if the UE performs intra-site inter-frequency handover, that is, the UE is switched from the supported frequency band not belonging to the UE in the original support capability message to the second frequency point belonging to the UE in the original support capability message, the base station will change the measurement threshold T of the a4 event of the second frequency point at this time₂A preset threshold T configured for the frequency point₂' that is, the measurement threshold configured by default in the base station is issued to the UE for measurement.

Under the scene that the UE performs in-station switching, if the UE is switched from the supporting frequency band which does not belong to the UE in the original supporting capability message to the supporting frequency band which belongs to the UE in the original supporting capability message, the measurement parameter of the supporting frequency band of the UE in the original supporting capability message is changed, and the measurement parameter is issued to the UE for measurement according to the measurement parameter pre-configured by the base station, so that the UE is prevented from accessing the frequency point which does not belong to the supporting frequency band range of the UE in the original supporting capability message again, and the base station is prevented from frequently initiating the terminal supporting capability query message to influence the wireless performance of the network.

In some embodiments of the present invention, when the UE is switched from the idle state to the service state, through steps S110 to S140, the base station may issue a measurement control message including an actual access frequency band, so as to avoid the problems of dropped call, offline or excessive RRC reestablishment times. But also causes the UE to be in a frequency band which is not within the range of the supported frequency band of the UE in the original support capability message when the UE switches from the traffic state to the idle state.

In some embodiments of the present invention, in an application scenario where the UE switches from a service state to an idle state, in order to enable the UE to preferentially access a supported frequency band of the UE in the original support capability message, after step S140, the method for processing a terminal frequency band further includes the following steps:

s410, judging whether the actual access frequency band of the UE belongs to the supporting frequency band of the UE in the original supporting capability message.

In the embodiment of the present invention, if the actual access frequency band of the UE does not belong to the supported frequency band of the UE in the original support capability message, step S420 is performed.

In the embodiment of the present invention, if the UE is switched from the service state to the idle state, and the actual access frequency band of the UE belongs to the supported frequency band of the UE in the original support capability message reported by the UE, the UE accesses the supported frequency band reported by the UE in the idle state.

S420, sending a Radio Resource Control (RRC) connection release message to the user terminal, wherein the RRC connection release message comprises the reselection priority of the actual access frequency band and the reselection priority of each supporting frequency band in the supporting frequency band information of the user terminal in the original supporting capacity information.

In an idle state, the UE is accessed into the supported frequency band of the UE in the original supporting capability message of the UE in a high priority mode, and the problems of potential call drop, offline or more RRC reconstruction times of the UE and the like under the condition that the actual accessed frequency band is not in the supported frequency band list reported by the UE are solved.
