Description

Scheduling method, user equipment and base station

Technical Field

The present invention relates to the field of communications, and in particular, to a scheduling method, a user equipment, and a base station.

Background

With the development of the internet of things, in order to better bear application of the internet of things on a mobile communication network, a concept of machine-to-machine communication (M2M) is proposed, and Machine Type Communication (MTC) is introduced on the mobile communication network, so that the mobile communication network is enhanced or optimized.

One optimization direction of the mobile communication network is to reduce the cost of the mobile communication terminal equipment and provide low-cost MTC user equipment based on an LTE (Long Term Evolution) network, so that the cost of the terminal equipment meets the requirement of the application of the Internet of things, and the application of the Internet of things is better borne on the LTE communication network. In order to provide low cost User Equipment (UE), one possible technique is to reduce the working (transmit/receive) bandwidth supported by the UE, i.e. to provide support for narrowband UEs in existing broadband network systems. In order to support more narrow-band UEs while reducing the operating bandwidth of the narrow-band UEs, it is necessary to divide multiple narrow bands in a wideband system for the narrow-band UEs, and the narrow-band UEs may select one narrow-band sub-band to access or stay. However, in a multi-narrowband scenario, since there is a narrowband UE staying in an idle state in multiple narrowband, a common message, for example, a system message, needs to be sent simultaneously on multiple narrowband to ensure that all UEs in different narrowband can receive the common message.

Since resource waste is caused by sending common messages on multiple narrow bands simultaneously, the narrow bands in the system are generally divided into functions, one narrow band is selected from the multiple downlink narrow bands to send the common messages, and the other narrow bands are used for scheduling and sending data of the narrow band UE.

The narrowband UE may receive the common message on the common message narrowband according to a certain rule. Taking system message updating as an example, the current method for updating system messages is to perform notification of system message updating in the previous updating period and send updated system messages in the next updating period. To ensure correct reception of the system message, the system message is usually sent multiple times over a system message time window, the length of which is a maximum of 40 ms. For the narrowband UE, when the system message needs to be received, the narrowband UE may leave the current narrowband, and receive the system message from the narrowband where the system message is located, that is, receive the system message on the common message narrowband. After the narrowband UE finishes receiving the system message, the narrowband UE returns to the original data narrowband for continuing data transceiving. Because the base station does not know when the narrowband UE completes the reception of the system message and returns to the narrowband where the narrowband UE originally stays, the base station cannot schedule the narrowband UE in the entire system message time window, but does not schedule the narrowband UE until the entire system message time window expires, thereby wasting time resources.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be understood that the solution of the present invention can be applied to various communication systems, such as: GSM (Global System for Mobile communication), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), GPRS (General Packet radio service), LTE (Long Term Evolution), LTE-a (Advanced Long Term Evolution), UMTS (Universal Mobile telecommunications System), etc. the embodiments of the present invention are not limited, but for convenience of description, the embodiments of the present invention will be described by taking an LTE network as an example.

The embodiment of the invention can be used for wireless networks of different systems. The radio access network may comprise different network elements in different systems. For example, the Network element of the Radio Access Network in LTE and LTE-a includes an eNB (eNodeB, evolved node b), the Network element of the Radio Access Network in WCDMA includes an RNC (Radio Network Controller) and a NodeB, and similarly, other wireless networks such as WiMax (Worldwide Interoperability for Microwave Access) may also use a scheme similar to the embodiment of the present invention, except that related modules in the base station system may be different.

It should also be understood that, in the embodiment of the present invention, the User Equipment (UE) or the terminal Equipment includes, but is not limited to, a Mobile Station (MS), a Mobile terminal (Mobile terminal), a Mobile phone (Mobile Telephone), a handset (handset), a portable device (portable device), and the like, and the User Equipment may also be various devices with certain sensing, calculating, executing, and communication capabilities in the internet of things, which may communicate with one or more core networks through a Radio Access Network (RAN). For example, the user equipment may be a mobile telephone (or "cellular" telephone), a computer with wireless communication capabilities, etc., and the user equipment may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device.

The embodiment of the invention can be mainly applied to the scene of dividing a plurality of narrow bands in a broadband system to support the access of the narrow band user equipment and dividing the narrow bands into a common message narrow band and a data narrow band. In this scenario, a common message, e.g., a system message, may be provided to multiple user equipments within a common message time window (preset time period) within one common message narrowband.

Fig. 1 is a schematic flow diagram of a scheduling method according to an embodiment of the present invention. The method of fig. 1 is performed by a user equipment, and includes the following.

And 110, the user equipment receives the public message sent by the base station on the narrow band of the public message in the public message time window.

For example, the base station may transmit the common message on the common message narrowband within a preset common message time window, so that the plurality of user equipments may receive the common message on the common message narrowband within the common message time window when needed. When the public message needs to be received, the user equipment leaves the current data narrow band and receives the public message on the public message narrow band where the public message is located.

The common message time window may refer to a preset time period for the base station to transmit the common message on the common message narrowband, and may be periodic and pre-configured at the base station and the user equipment side.

And 120, the user equipment switches from the public message narrowband to the data narrowband when the receiving of the public message is completed.

After the user equipment completes the reception of the public message, the user equipment leaves the public message narrow band, returns to the original data narrow band, or jumps to another data narrow band.

And 130, the user equipment informs the base station that the user equipment completes receiving the public message, so that the base station schedules the user equipment to transmit data on the data narrow band in the remaining time of the time window of the public message.

For example, when the ue completes receiving the common message, the ue may notify the base station of the completion of receiving the common message by using a specific signaling message in the remaining time of the common message time window, or notify the base station of the completion of receiving the common message by using a transmission exception of a preset signaling message in the common message time window, or notify the base station of the completion of receiving the common message by carrying indication information in the preset signaling, or notify the base station of the completion of receiving the common message by using a dedicated signaling message. The base station can know that the user equipment has finished receiving the public message and switches to the data narrowband to prepare for receiving data according to the notification of the user equipment, namely, the base station can know that the user equipment can receive the data, so that the data scheduling can be carried out on the user equipment in time.

According to the embodiment of the invention, the user equipment can timely enable the base station to know that the user equipment completes receiving the public message, so that the base station is prevented from scheduling the user equipment until the time window of the public message expires, and the utilization rate of time resources is improved.

In 130, the user equipment may inform the base station that the reception of the common message by the user equipment is completed through the reference signal.

For example, the Reference Signal may be an SRS transmitted by the user equipment to the base station on different Sounding Reference Signal (SRS) narrowband according to a preset frequency hopping rule. The base station may be notified of the completion of the reception of the common message according to the abnormality of the SRS transmission in the common message time window, in other words, the SRS is normally transmitted at other times except the common message time window, and the SRS is abnormally transmitted in the common message time window, so that the base station can know that the reception of the common message by the user equipment has been completed according to the abnormality.

Optionally, as another embodiment, in 130, the ue may notify the base station that the ue completes receiving the common message by sending a scheduling request to the base station.

For example, if the user equipment has a resource for transmitting a scheduling request within the common message time window after completing reception of the common message, the scheduling request is transmitted to the base station on the resource, in other words, within the common message reception window, the user equipment does not transmit the scheduling request if reception of the common message is not completed; the user equipment transmits the scheduling request only after completing reception of the common message and for a scheduling request resource remaining in a common message reception window. And if the base station receives the scheduling request in the common message time window, determining that the user equipment completes receiving the common message.

Optionally, as another embodiment, in 130, the ue may notify the base station that the ue receives the common message by initiating a random access procedure.

For example, the ue initiates a random access procedure in the common message time window, if the base station identifies the random access procedure initiated by the ue in the common message time window, it considers that the ue completes receiving the common message, or the ue indicates that the ue completes receiving the common message by using the uplink message carrying indication information in the random access procedure, and if the base station receives the uplink message in the common message time window, it determines that the ue completes receiving the common message.

Optionally, as another embodiment, in 130, the ue may notify the base station through a dedicated message that the ue completes receiving the common message.

For example, after the user equipment completes receiving the common message, the user equipment may send dedicated signaling to the base station to inform the base station that the user equipment completes receiving the common message.

It should be understood that the base station may also be informed by a combination of at least two of the above-mentioned several informing manners. For example, priorities may be set for different notification manners, and the notification manners may be selected according to the priorities. For example, assuming that the priority of the notification method based on the scheduling request is higher than that of the notification method based on the reference signal, and the priority of the notification method based on the reference signal is higher than that of the notification method based on the dedicated message, after the ue completes receiving the common message, if the ue has the scheduling resource, the notification method based on the scheduling request is preferentially adopted, otherwise, the notification method based on the reference signal is selected, and the notification method based on the dedicated message is selected only when the ue cannot notify the base station using the above method, so as to save signaling overhead as much as possible.

According to the embodiment of the present invention, in 130, the ue may notify the base station that the ue completes receiving the common message by not transmitting the SRS on the first SRS narrowband before the completion of receiving the common message and transmitting the SRS on the first SRS narrowband according to a preset rule after the completion of receiving the common message.

For example, the first SRS narrowband is a preset narrowband of the at least one SRS narrowband. The plurality of SRSs may be transmitted according to a preset frequency hopping rule outside the common message time window, and within the common message time window, the SRS may be transmitted on the first SRS narrowband only after the ue completes receiving the common message, so that the base station may determine that the ue completes receiving the common message according to the change or abnormality.

According to an embodiment of the present invention, in 130, the ue may transmit the SRS on the at least one SRS narrowband according to a preset rule before the common message reception is completed, and stop transmitting the SRS on one of the at least one SRS narrowband when the common message reception is completed, so as to notify the base station that the common message reception is completed.

For example, the SRS narrowband for which transmission of the SRS is stopped may be one narrowband of the at least one SRS narrowband. The plurality of SRSs may be transmitted according to a preset frequency hopping rule outside the common message time window, and may also be transmitted according to a preset frequency hopping rule within the common message time window, and only after the reception of the common message by the user equipment is completed, the transmission of the SRS on the narrowband to which the SRS should be transmitted according to the preset frequency hopping rule may be stopped, so that the base station may determine that the reception of the common message by the user equipment is completed according to the change or the abnormality. In other words, after entering the common message receiving window, before the common message reception is completed, the SRS signal is transmitted on the corresponding SRS narrowband according to the existing rule; after the reception of the common message is completed, the SRS signal is intentionally not transmitted on the SRS narrowband on which the SRS signal should be transmitted according to the existing rule. The SRS narrowband to stop transmitting the SRS is related to the time when the reception of the common message is completed, for example, if the user equipment should transmit the SRS on the SRS narrowband numbered 0 after the reception of the common message is completed, the SRS transmission on the SRS narrowband numbered 0 is stopped, and for example, if the user equipment should transmit the SRS on the SRS narrowband numbered 3 after the reception of the common message is completed, the SRS transmission on the SRS narrowband numbered 3 is stopped.

Fig. 2 is a schematic flow chart of a scheduling method according to another embodiment of the present invention. The embodiment of fig. 2 is performed by a base station, corresponding to the method of fig. 1, including the following. To avoid redundancy, detailed description is appropriately omitted herein.

The base station sends 210 the common message to the user equipment on the common message narrowband within the common message time window.

220, the base station determines that the reception of the common message by the user equipment is completed according to the notification of the user equipment.

And 230, when the base station determines that the user equipment completes the reception of the common message, scheduling the user equipment to transmit data on the data narrow band in the remaining time of the common message time window.

According to the embodiment of the invention, the base station can timely know that the receiving of the public message by the user equipment is finished, so that the user equipment can be timely scheduled, and the utilization rate of time resources is improved.

In 220, the base station may determine that the reception of the common message by the user equipment is completed according to the reference signal transmitted by the user equipment.

Optionally, as another embodiment, in 220, the base station may determine that the reception of the common message by the user equipment is completed according to a scheduling request sent by the user equipment.

Optionally, as another embodiment, in 220, the base station determines that the reception of the common message by the user equipment is completed according to a random access procedure initiated by the user equipment.

Optionally, as another embodiment, in 220, the base station may determine that the reception of the common message by the user equipment is completed according to the dedicated message sent by the user equipment.

According to the embodiment of the present invention, in 220, the base station may receive an SRS on the first SRS narrowband according to a preset rule, and determine that the reception of the common message by the user equipment is completed when the SRS is received on the first SRS narrowband.

According to the embodiment of the present invention, in 220, the base station may receive an SRS on at least one SRS narrowband according to a preset rule, and when the base station does not receive an SRS on one of the at least one SRS narrowband, determine that the receiving of the common message by the user equipment is completed.

Embodiments of the present invention are described in more detail below with reference to specific examples.

Fig. 3 is a schematic flow diagram of a scheduling process according to one embodiment of the invention. In fig. 3, the base station may be an eNodeB and the user equipment may be a narrowband user equipment. The eNodeB represents the controlling base station of the current serving cell of the user equipment, but the invention is not limited to the specific standard represented by this term, but can be similarly applied to other forms of base stations. In the embodiment of fig. 3, the ue configures an SRS narrowband for SRS reporting.

The base station transmits the common message on the common message narrowband within the common message time window 310.

For example, at least one common message narrowband (e.g., one common message narrowband) may be configured for transmission and reception of common messages. The base station may periodically transmit a plurality of times the common message on the common message narrowband within the common message time window so that a plurality of user equipments can receive the common message transmitted on the common message narrowband within the common message time window. The common message time window may be preset, for example, to 40 ms.

The user equipment determines that the common message needs to be received 320.

For example, the common message may be a system message, and after receiving a System Information (SI) update notification, the ue knows that the content of the system message has been updated, and therefore needs to receive the updated system message.

In addition, in the random access procedure, when receiving the random access response, the common message also needs to be received on the common message narrowband.

The user equipment receives the common message on the common message narrowband within the common message time window 330.

When the user equipment determines that the public message needs to be received, the user equipment can leave the original data narrow band within a preset time window, jump to the public message narrow band, and receive the public message sent by the base station on the public message narrow band.

340, the user equipment judges whether the reception of the public message is finished, if the user equipment finishes the reception of the public message, step 350 is executed, otherwise, step 330 is continuously executed.

For example, the user equipment receives or listens for the common message on the common message narrowband within the common message time window until the reception of the common message is completed or successfully received.

The user equipment switches to the data narrowband and transmits the SRS on the first SRS narrowband 350.

For example, after the ue completes receiving the common message, it may return to the original data narrowband and notify the base station through the SRS that it has completed receiving the common message. For example, the user equipment may transmit an SRS (e.g., a series of pulses) on a particular (or preset) SRS narrowband (e.g., periodically) to indicate that the user equipment has completed receiving the common message.

360, the base station determines whether the SRS is received on the first SRS narrowband within the common message time window, if the SRS is received on the first SRS narrowband within the common message time window, step 370 is executed, otherwise step 380 is executed.

In this example, the following settings or conventions may be performed on the user equipment side and the base station side: at the user equipment side, in the common message time window, if the user equipment does not finish receiving the common message, the SRS is not sent on the specific SRS narrow band, and if the user equipment finishes receiving the common message, the SRS is sent on the specific SRS narrow band; at the base station side, if the SRS is received on the specific SRS narrowband within the common message time window, it is determined that the user equipment has completed receiving the common message.

The base station schedules the user equipment within the common message time window 370.

If the base station receives the SRS transmitted by the user equipment on the specific SRS narrowband within the common message time window, the base station may determine that the user equipment has completed receiving the common message, that is, it is known that the user equipment may transmit data through the data narrowband. Although the current common message time window is not expired, the base station can also schedule the user equipment in advance, thereby improving the utilization rate of time resources.

In addition, the base station is informed that the user equipment has finished receiving the public message by adopting a mode of sending the SRS on the specific SRS narrow band in the public message time window without adopting special signaling, thereby saving signaling overhead.

380, the base station schedules the user equipment upon expiration of the common message time window.

If the base station does not receive the SRS sent by the user equipment on the specific SRS narrow band until the common message time window expires, the base station does not schedule the user equipment for data transmission after the common message time window expires.

Fig. 4 is a schematic flow chart diagram of a scheduling process according to another embodiment of the present invention. In fig. 4, the base station may be an eNodeB and the user equipment may be a narrowband user equipment. The eNodeB represents the controlling base station of the current serving cell of the user equipment, but the invention is not limited to the specific standard represented by this term, but can be similarly applied to other forms of base stations. In the embodiment of fig. 4, the ue is configured to report the SRS on the narrowband SRS. 410, 420 and 430 of fig. 4 are similar to 310, 320 and 330 of fig. 3 and will not be described again.

The base station transmits the common message on the common message narrowband within the common message time window 410.

The user equipment determines 420 that the common message needs to be received.

The user equipment receives the common message on the common message narrowband within the common message time window 430.

440, the user equipment determines whether the reception of the common message is completed, if the user equipment completes the reception of the common message, step 450 is performed, otherwise, step 445 is performed.

445, the user equipment transmits the SRS on the at least one SRS narrowband on a regular basis within the common message time window.

The user equipment transmits the SRS on the at least one SRS narrowband according to a preset rule (for example, a frequency hopping rule) before completing the reception of the common message in the common message time window.

The user equipment switches to the data narrowband and stops transmitting SRS on one of the at least one SRS narrowband 450.

For example, after the user equipment completes the reception of the common message, the user equipment can return to the original data narrowband. If the user equipment completes receiving the common message in the common message time window, the SRS is not transmitted on the SRS narrow band which should transmit the SRS in the at least one SRS narrow band, for example, if the reception of the common message is completed, the SRS should be transmitted on the SRS narrow band numbered 0 according to the frequency hopping rule, and at this time, the user equipment intentionally does not transmit the SRS on the SRS narrow band numbered 0.

460, the base station determines whether the SRS is not received on one of the at least one SRS narrowband within the common message time window, if the SRS is not received on one of the at least one SRS narrowband within the common message time window, then step 470 is performed, otherwise step 480 is performed.

In this example, the following settings or conventions may be performed on the user equipment side and the base station side: on the side of the user equipment, in a common message time window, if the user equipment does not finish receiving the common message, the user equipment transmits the SRS according to the existing SRS frequency hopping rule (for example, periodically on different SRS narrow bands), otherwise, in the common message time window, on a certain specific SRS narrow band which needs to transmit the SRS according to the existing SRS frequency hopping rule, the SRS is not transmitted; at the base station side, in the common message time window, if the user equipment does not receive the SRS on the SRS narrow band which should receive the SRS according to the existing SRS frequency hopping rule, the user equipment is determined to finish the common message receiving, otherwise, the user equipment is determined to not finish the common message receiving.

470, the base station schedules the user equipment within the common message time window.

If the base station does not receive the SRS periodically transmitted by the user equipment on one of the at least one SRS narrowband within the common message time window, the base station may determine that the user equipment has completed receiving the common message, that is, it is known that the user equipment may transmit data through the data narrowband. Although the common message time window is not expired, the base station can schedule the user equipment in advance, thereby improving the utilization rate of time resources.

In addition, the base station is informed that the user equipment has finished receiving the common message by periodically transmitting the SRS on the at least one SRS narrow band in the common message time window and stopping transmitting the SRS on one of the at least one SRS narrow band when the common message is received, and dedicated signaling is not required, so that the signaling overhead is saved.

The base station schedules the user equipment upon expiration of the common message time window 480.

If the base station can periodically receive the SRS sent by the user equipment on at least one SRS narrow band before the common message time window expires, the base station schedules the user equipment for data transmission when the common message time window expires.

The user equipment determines 520 that the common message needs to be received.

The user equipment receives the common message on the common message narrowband within the common message time window 530.

540, the user equipment determines whether the reception of the public message is completed, if the user equipment completes the reception of the public message, step 550 is executed, otherwise, step 530 is continuously executed.

The user equipment switches to the data narrowband and sends a scheduling request to the base station 550.

For example, after the user equipment completes the reception of the common message, the user equipment can return to the original data narrowband. If the user equipment is configured with SR resources and the SR resources fall within the common message time window after the user equipment completes reception of the common message, the user equipment may transmit an SR request to the base station indicating that it completes reception of the common message. According to the embodiment of the present invention, the sequence of the step of performing the handover to the data narrowband and the step of sending the scheduling request to the base station is not limited, for example, the user equipment may send the scheduling request to the base station first and then switch to the data narrowband, or may send the scheduling request to the base station while switching to the data narrowband.

560, the base station determines whether the scheduling request is received in the common message time window, if the base station receives the scheduling request in the common message time window, step 570 is performed, otherwise step 580 is performed.

In this example, the following settings or conventions may be performed on the user equipment side and the base station side: on the side of the user equipment, in the common message time window, if the user equipment does not finish receiving the common message, the user equipment does not send any SR request, otherwise, if the user equipment has SR resources in the common message time window after the user equipment finishes receiving the common message, the user equipment sends the SR request. And the base station side determines that the user equipment completes the public message reception if receiving the SR request in the public message time window, otherwise, determines that the user equipment does not complete the public message reception.

570, the base station schedules the user equipments within the common message time window.

If the base station receives the scheduling request sent by the user equipment in the public message time window, the base station can determine that the user equipment has finished receiving the public message, that is, it is known that the user equipment can transmit data through the data narrowband. Although the current common message time window is not expired, the base station can also schedule the user equipment in advance, thereby improving the utilization rate of time resources.

In addition, the base station is informed that the user equipment has finished receiving the public message by adopting a mode of sending the scheduling request in the public message time window without adopting a special signaling, so that the signaling overhead is saved.

580, the base station schedules the user equipment when the common message time window expires.

And if the base station does not receive the scheduling request sent by the user equipment until the public message time window expires, the base station schedules the user equipment for data transmission when the public message time window expires.

In fig. 6, the base station may be an eNodeB and the user equipment may be a narrowband user equipment. The eNodeB represents the controlling base station of the current serving cell of the user equipment, but the invention is not limited to the specific standard represented by this term, but can be similarly applied to other forms of base stations. In the embodiment of fig. 6, the base station is informed of the completion of reception of the common message through a random access procedure. 610, 620 and 630 of FIG. 6 are similar to 310, 320 and 330 of FIG. 3 and will not be described again here.

640, the user equipment determines whether the reception of the common message is completed, if the user equipment completes the reception of the common message, step 650 is performed, otherwise, step 630 is continuously performed.

The user equipment switches to the data narrowband and issues a random access request 650.

For example, after the user equipment completes the reception of the common message, the user equipment can return to the original data narrowband. The user equipment may inform the base station that the user equipment completes reception of the common message by issuing a random access procedure, i.e., a contention-based or non-contention based RACH procedure, after completing reception of the common message. According to the embodiment of the present invention, the order of the step of performing the handover to the data narrowband and the step of sending the random access request is not limited, for example, the user equipment may send the random access request first and then switch to the data narrowband, or may send the random access request while switching to the data narrowband.

Optionally, the ue may also carry indication information in an MSG 3 (message 3) message of the random access procedure, indicating that the ue completes receiving the public message.

660, the base station determines whether the random access request is identified within the common message time window, if the base station identifies the random access request within the common message time window, step 670 is performed, otherwise, step 680 is performed.

And if the base station can identify the random access sent by the user equipment, determining that the user equipment completes the reception of the public message.

In this example, the following settings or conventions may be performed on the user equipment side and the base station side: and at the user equipment side, in the public message time window, if the user equipment does not finish receiving the public message, the user equipment continues to receive the public message, otherwise, the user equipment initiates a random access process. And the base station side determines that the user equipment completes the public message receiving if the random access process initiated by the user equipment is identified in the public message time window.

The base station schedules the user equipment within the common message time window 670.

If the base station identifies random access within the time window of the common message, the base station may determine that the user equipment has completed receiving the common message, i.e., learn that the user equipment may transmit data through the data narrowband. Although the common message time window is not expired, the base station can schedule the user equipment in advance, thereby improving the utilization rate of time resources.

In addition, the base station is informed that the user equipment has finished receiving the public message by adopting a mode of sending random access in the public message time window without adopting special signaling, thereby saving signaling overhead.

680, the base station schedules the user equipment when the common message time window expires.

If the base station does not recognize the random access until the expiration of the common message time window, the base station does not schedule the user equipment for data transmission when the common message time window expires.

And 750, the user equipment switches to the data narrowband and informs the base station of the completion of the reception of the public message by the user equipment through the dedicated message.

For example, after the user equipment completes the reception of the common message, the user equipment can return to the original data narrowband. After the user equipment completes receiving the public message, the user equipment can inform the base station that the user equipment completes receiving the public message through the special message under the condition that the base station allocates uplink resources for the user equipment. According to the embodiment of the present invention, the sequence of the step of performing the handover to the data narrowband and the step of notifying the base station through the dedicated message is not limited, for example, the user equipment may notify the base station through the dedicated message first and then switch to the data narrowband, or may notify the base station through the dedicated message while switching to the data narrowband.

760, the base station determines whether the dedicated message sent by the user equipment is received within the common message time window, if the base station receives the dedicated message sent by the user equipment within the common message time window, step 770 is executed, otherwise step 780 is executed.
