UE management method, UE and base station

Technical field

The present invention relates to the field of mobile communications technologies, and in particular, to a UE management method, a UE, and a base station.

Background technique

With the rapid development of mobile communication technology, the long-term evolution (English: Long Term Evolution, LTE) network has been rapidly deployed and popularized. The number of LTE users has increased dramatically, and emerging services represented by high-definition multimedia streaming services have emerged rapidly. There are more and more applications installed on the user equipment (English: User Equipment, abbreviated as UE). These applications frequently trigger the UE to establish a radio resource control (English: Radio Resource Control, abbreviation: RRC) connection with the LTE network. Further establishing a connection with the application server for data exchange, and the process of establishing the RRC connection, that is, the process in which the UE enters the connection (English: CONNECTED) state from the idle (English: IDLE) state, this process generates a large amount of signaling. Including RRC, Radio Link Control (English: Radio Link Control, abbreviation: RLC), Media Access Control (English: Media Access Control, abbreviation: MAC), Physical Downlink Control Channel (English: Physical Downlink Control Channel, abbreviation: PDCCH) Such as signaling. In addition, the application server of each application also frequently pushes information to the UE through the LTE network, resulting in frequent paging procedures. If the RRC connection is not established in the paging process, the RRC connection needs to be established first, and the entire paging process is generated. Paging signaling. It can be seen that frequently establishing an RRC connection and performing a paging procedure cause a severe signaling load on the LTE network.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Among them, according to the current 3rd Generation Partnership Project (English: 3rd Generation Partnership Project, 3GPP) protocol, UEs in the LTE network have two RRC states, namely, an idle state and a connected state, and the two RRC states. The corresponding mobility management mechanism is a cell reselection and a cell handover, and the UE performs a cell reselection process when in an idle state, and performs a cell handover procedure when the UE is in a connected state.

It should be noted that the cell reselection can be implemented by means of system messages, and the power consumption is small, and the cell handover is accompanied by the generation of handover signaling, and the UE generates a large amount of handover signaling when there is no service transmission, which may cause the network. The waste of resources will also lead to more power consumption of the UE.

The UE described in the embodiment of the present invention may be a universal type UE, such as a smart phone. (including Android phones, iOS phones, Windows Phone phones, etc.), tablets, PDAs, laptops, mobile Internet devices (English: Mobile Internet Device, abbreviation: MID) or wearable devices, etc., can also be machine type communication ( English: Machine Type Communication, abbreviation: MTC) UE, the above UE is only an example, not exhaustive, including but not limited to the UE of the above type.

FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for managing a UE according to an embodiment of the present invention. The management method of the UE described in this embodiment is mainly described from the UE side, and includes the following steps:

S101. The UE establishes an RRC connection with the base station according to the service transmission request, and performs cell handover according to the handover decision of the base station.

The service transmission may include a service initiated by the UE and a service pushed by the network side.

Specifically, the UE enters an idle state after being powered on, and establishes an RRC connection with the base station when initiating or receiving a service transmission request, the UE enters a connected state by the idle state, and establishes a radio bearer with the base station (English: Radio Bearer, abbreviation) : RB), the service transmission is performed by the RB, and the cell handover procedure is triggered during the mobile process or at the cell edge, and the UE sends a measurement report for the serving cell and the neighboring cell to the base station, and the base station performs the measurement report according to the measurement report. The handover decision is made, and the UE is notified to switch to the new cell or not to switch according to the handover decision.

S102: After the UE service transmission ends, when the duration that the UE does not receive the service transmission obtained by the timer is up to a preset duration, the UE performs cell reselection according to the cell measurement result.

The preset duration may be valid for some or all UEs served by the base station, or may be determined separately by the base station according to the terminal type and/or service type of the UE, that is, only valid for the UE.

Specifically, the UE maintains an RRC connection established with the base station after the end of the service transmission, so as to reduce the frequency of establishing the RRC connection by the UE, and reduce the signaling related to the RRC connection establishment and the generation of the paging signaling.

Further, the base station may start a timer when the UE service transmission ends, and if the timer duration of the timer reaches the preset duration during the period when the UE has no service transmission, the UE may receive the base station list. The RRC signaling used to indicate that the UE performs cell reselection is not performed. Performing a cell reselection procedure, that is, the UE performs measurement on the serving cell and the neighboring cell. If the cell measurement result meets the relevant criteria of the cell reselection (including the R criterion and the S criterion), the UE selects a new cell to camp. .

S103. When the UE performs service transmission again according to the service transmission request, the UE performs cell handover according to the handover decision of the base station.

Specifically, when the UE performs the cell reselection process, if the UE initiates or receives a service transmission request and performs a service transmission, the UE receives the RRC unicast by the base station to indicate that the UE performs cell handover. Signaling, the cell handover procedure is performed without performing a cell reselection procedure.

In some feasible implementation manners, the preset duration may be notified to the UE by the base station by means of broadcast or unicast RRC signaling, and the UE starts timing when the service transmission ends, and if there is no service transmission, if If the timer duration of the timer reaches the preset duration, the UE automatically performs a cell reselection procedure without performing a cell handover procedure. If the UE initiates or receives a service transmission request for service transmission, the UE is used. The cell handover procedure is automatically performed without performing a cell reselection procedure.

In some feasible implementation manners, if the duration that the UE or the UE does not receive the service transmission by the UE does not reach the preset duration, the UE continues the cell handover procedure.

FIG. 2 is a schematic flowchart diagram of a second embodiment of a method for managing a UE according to an embodiment of the present invention. The management method of the UE described in this embodiment is mainly described from the UE side, and includes the following steps:

S201. The UE establishes an RRC connection with the base station according to the service transmission request, and performs cell handover according to the handover decision of the base station.

S202. After the UE service transmission ends, the UE receives a preset duration that the UE does not have a service transmission obtained by the timer that is started by the base station when the UE service transmission ends, and the preset duration reaches a preset. RRC signaling for unicast time, the RRC signaling includes an identifier for indicating that the UE performs cell reselection.

S203. The UE performs cell reselection according to the cell measurement result in response to the RRC signaling.

On the basis of the existing 3GPP protocol, an RRC state may be defined for the UE in the LTE network, for example, it may be named as a light connection state (English: LIGHT_CONNECTED), and the naming name is not limited in the embodiment of the present invention. . The difference between the light connection state and the existing connection state may only be different in the mobility management mechanism. The light connection state is the same as the mobility management mechanism corresponding to the existing idle state, and both are cell reselection, and the existing connection is The mobility management mechanism corresponding to the state is cell handover.

The preset duration may be valid for some or all UEs served by the base station, or may be determined separately by the base station according to the terminal type and/or service type of the UE, that is, only valid for the UE. For example, the frequency of the service transmission by the UE of the MTC type is lower than that of the UE of the general type, and the service transmission may be delayed. The base station may configure a shorter preset duration for the UE of the MTC type, so that the UE of the MTC type After the end of the service transmission, the connection state can be switched to the light connection state as soon as possible, and the cell handover procedure is stopped to perform the cell reselection procedure, thereby greatly reducing the signaling load of the network and the power consumption of the MTC type UE; The UE has a high frequency and real-time requirement for general service transmission. The base station can configure a longer duration of the preset time for the general-purpose UE, thereby effectively reducing the signaling load of the network while satisfying the service transmission requirement. And the power consumption of a generic type of UE. For example, for a UE whose current service is a video service or a game service, the possibility of performing other services is low, and the base station can configure a shorter preset duration, so that the UE can remain in the light connection state for a long time. The cell reselection procedure is performed, thereby effectively reducing the signaling load of the network and the power consumption of the UE.

The identifier used to indicate that the UE performs cell reselection may specifically be a flag bit True (or False).

S204. When the UE performs service transmission again according to the service transmission request, the UE performs cell handover according to the handover decision of the base station.

The identifier used to indicate that the UE performs cell handover may specifically be a flag bit False (or True).

For example, if the preset duration is 1 second, as shown in FIG. 3, at the location #1, the UE is powered on and enters an idle state, and when the UE moves to the location #2, a video service is generated, and the UE and the base station #2 Establishing an RRC connection, switching from the idle state to the connected state, and performing a cell handover procedure, when the UE moves to the location #3, the video service ends, and the base station #2 obtains the duration that the UE does not have the service transmission by using the startup timer. When the unicast RRC signaling is sent to the UE, the UE is instructed to switch from the connected state to the light connected state, and the cell reselection process is performed without performing the cell handover procedure. When the UE moves to the location #4, if the signal strength of the base station #3 is stronger than the signal strength of the base station #2, since the UE is in the light connection state at this time, the cell reselection process is performed, and the cell handover procedure is not performed. Therefore, the UE can select the cell camping of the base station #3, and can greatly reduce the handover signaling generated when the UE moves between cells or at the cell edge, and the related information of the RRC connection establishment that is generated when there is no service transmission to be changed to the service transmission. Order and paging signaling, etc., and reduce the power consumption of the UE.

In the embodiment of the present invention, the RRC state of the light connection state is newly defined, the UE establishes an RRC connection with the base station based on the service transmission request, performs service transmission, and performs cell handover according to the handover decision sent by the base station; after the service transmission ends, the UE And maintaining the RRC connection, in response to the state switching indication sent by the base station when the duration of the UE that has not received the service transmission obtained by the timer is up to a preset duration, switching from the connected state to the lightly connected state, not performing Performing a cell reselection process in the cell handover process; when the UE performs service transmission again based on the service transmission request, the UE switches from the light connection state to the connection state in response to the state switching indication sent by the base station, and does not perform the cell reselection process. The cell handover procedure is performed, thereby reducing signaling generation, effectively reducing signaling load of the network, and reducing power consumption of the UE.

FIG. 4 is a schematic flowchart diagram of a third embodiment of a method for managing a UE according to an embodiment of the present invention. The management method of the UE described in this embodiment is mainly described from the UE side, and includes the following steps:

S401. The UE receives the RRC signaling that is broadcast by the base station and includes the first duration, and sets the preset duration to the first duration according to the RRC signaling including the first duration.

In combination with the provisions of the existing 3GPP protocol, the connection state in the RRC state can be adjusted. The mobility management mechanism, that is, the mobility management mechanism combining cell handover and cell reselection for the UE in the connected state. When the UE is in the connected state, the UE performs the cell reselection process without performing the cell handover procedure when the duration of the service transmission does not reach the preset duration. Otherwise, the cell handover procedure is performed without performing the cell reselection procedure.

The first duration may be valid for some or all UEs served by the base station, and may be used as a default value of the network side configuration, for example, 1 second.

Specifically, the base station may periodically notify the UE served by the base station by using a broadcast, and the UE sets the preset duration to the first duration.

S402. The UE establishes an RRC connection with the base station according to the service transmission request, and performs cell handover according to the handover decision of the base station.

S403. The UE receives the RRC signaling including the second duration of the unicast by the base station, and sets the preset duration to the second duration according to the RRC signaling including the second duration.

Specifically, the base station may separately configure the second duration for the UE according to the terminal type and/or the service type of the UE, if the UE receives the RRC connection with the base station, and receives the base station before the UE service transmission ends. If the unicast includes the RRC signaling of the second duration, the UE sets the preset duration to the second duration, that is, the second duration configured by the base station for the UE may cover the default value broadcasted by the base station ( That is, the first duration is long, so that the UE can be configured with a preset preset duration according to different terminal types and service types.

In some feasible implementation manners, the base station may not broadcast the default value (that is, the first duration), but separately configure the UE according to the terminal type and/or service type of the UE each time the UE performs service transmission. The preset duration is used, and the preset duration is notified to the UE by using unicast RRC signaling, that is, the base station does not uniformly configure the preset duration for the serving UE, but separately configures the preset duration for each UE.

S404: The UE starts a timer when the service transmission ends, and acquires a duration that the UE does not have a service transmission, which is obtained by the timer.

S405. The UE performs cell reselection according to the cell measurement result when the duration that the UE does not have the service transmission reaches the preset duration.

S406. When the UE performs service transmission again according to the service transmission request, the UE performs cell handover according to the handover decision of the base station.

Specifically, after the end of the service transmission, the UE maintains the RRC connection established with the base station and is always in the connected state. The UE starts the timer at the end of the service transmission. If the timer duration of the timer reaches the preset duration during the period of no service transmission, the UE automatically performs the cell reselection procedure without performing the cell handover procedure.

Further, if the UE initiates or receives a service transmission request for service transmission again, the UE automatically performs a cell handover procedure without performing a cell reselection procedure.

For example, as shown in FIG. 3, at the location #1, the UE is powered on and enters an idle state, and the base station #1, the base station #2, and the base station #3 can set the first duration by broadcasting RRC signaling (can be set as the network side). The default value, for example, 1 second, is notified to the respective serving UE, and the UE sets the preset duration to the first duration. When the UE moves to the location #2, a video service is generated, the UE establishes an RRC connection with the base station #2, switches from the idle state to the connected state, and performs a cell handover procedure, and the base station #2 can set the terminal type according to the UE. And the second time length (for example, 2 seconds) determined by the service type is notified to the UE by using unicast RRC signaling, where the second duration is only valid for the UE, and the UE sets the preset duration to the second duration. . When the UE moves to the location #3, the video service ends, and the RRC connection established with the base station #2 is always in the connected state. If the UE obtains the self-service transmission by the startup timer, the duration of the service is up to 2 seconds (ie, In the second time period, the UE automatically performs a cell reselection procedure without performing a cell handover procedure. When the UE moves to the location #4, if the signal strength of the base station #3 is stronger than the signal strength of the base station #2, since the UE performs the cell reselection procedure at this time, the UE can select the cell resident of the base station #3. Without performing cell handover, the handover signaling generated when the UE moves between cells can be greatly reduced, the related signaling of RRC connection establishment and the paging signaling generated when there is no service transmission to be changed from the service transmission, and paging signaling, etc., and the UE is lowered. Power consumption.

In the embodiment of the present invention, the mobility management mechanism corresponding to the connection state is adjusted, and the UE receives the RRC signaling that is broadcast by the base station, including the first duration, and sets the preset duration to the first duration, and establishes an RRC with the base station based on the service transmission request. Connecting, performing service transmission, and performing cell handover according to a handover decision sent by the base station; if the UE receives the RRC signaling including the second duration of the unicast by the base station, the UE sets the preset duration to the second Duration: after the end of the service transmission, the UE maintains the RRC connection established with the base station and is always in the connected state, and starts the timer when the service transmission ends, and if the timer duration of the timer reaches during the no traffic transmission When the preset duration is long, the UE automatically performs a cell reselection process without performing a cell handover procedure, when the UE is based on service transmission. When requesting the service transmission again, the UE performs the cell handover procedure according to the handover decision of the base station without performing the cell reselection procedure, which can reduce the signaling generation, effectively reduce the signaling load of the network, and reduce the power consumption of the UE.

FIG. 5 is a schematic flowchart diagram of a fourth embodiment of a method for managing a UE according to an embodiment of the present invention. The management method of the UE described in this embodiment is mainly described from the side of the base station, and includes the following steps:

S501. The base station establishes an RRC connection with the UE according to a service transmission request.

Specifically, the UE enters an idle state after being powered on. When the UE initiates or receives a service transmission request, the base station establishes an RRC connection with the UE, and the UE enters a connected state by the idle state, and the base station establishes an RB with the UE. Traffic is transmitted through the RB.

S502. The base station starts a timer when the UE service transmission ends, and acquires a duration that the UE does not have a service transmission, which is obtained by the timer.

S503: The eNB unicasts RRC signaling including an identifier for indicating that the UE performs cell reselection to the UE when the duration that the UE does not have a service transmission reaches a preset duration.

On the basis of the existing 3GPP protocol, an RRC state may be defined for the UE in the LTE network, for example, it may be named as a light connection state (English: LIGHT_CONNECTED). The name of the embodiment of the present invention is not limited. The difference between the light connection state and the existing connection state may only be different in the mobility management mechanism. The light connection state is the same as the mobility management mechanism corresponding to the existing idle state, and both are cell reselection, and the existing connection is The mobility management mechanism corresponding to the state is cell handover.

Specifically, after the UE service transmission ends, the base station maintains an RRC connection established with the UE. When the UE starts the timer at the end of the service transmission, the base station starts timing. When the UE has no service transmission period, if the timer duration of the timer reaches the preset duration, the base station indicates that the UE is switched from the connected state to the light connection. The cell reselection process is performed without performing a cell handover procedure.

S504. The eNB unicasts RRC signaling including an identifier for indicating that the UE performs cell handover, to the UE when detecting that the UE performs service transmission again according to the service transmission request.

S505. The base station sends a measurement configuration parameter to the UE, and receives a measurement report generated by the UE after performing measurement on the cell according to the measurement configuration parameter.

S506. The base station makes a handover decision according to the measurement report, and sends the handover decision to the UE.

Specifically, when the UE performs the cell reselection process, if the UE performs the service transmission again when the UE initiates or receives the service transmission request, the base station unicasts the RRC signaling used by the UE to indicate the UE to perform the cell handover. The UE is switched from the light connection state to the connected state, that is, the cell handover procedure is performed without performing the cell reselection procedure. If the base station detects that the UE needs to perform service transmission again, the base station unicasts to the UE RRC signaling including an identifier for indicating that the UE performs cell handover, and then the UE switches from the light connection state in response to the RRC signaling. In the connection state, the cell handover process is performed without performing the cell reselection process, that is, the base station sends measurement configuration parameters to the UE, including a measurement object, a cell list, a report mode, a measurement identifier, a time parameter, and the like, and the UE according to the measurement The configuration parameter measures the serving cell and the neighboring cell and generates a measurement report. The base station receives the measurement report reported by the UE, performs a handover decision according to the measurement report, and notifies the UE to switch to a new cell or not to switch according to the handover decision.

In the embodiment of the present invention, the RRC state of the light connection state is newly defined, and the base station establishes an RRC connection with the UE based on the service transmission request, and the UE switches from the idle state to the connected state to perform service transmission, and performs a handover decision according to the base station. a cell handover; the base station starts a timer when the UE service transmission ends, and obtains a duration that the UE does not have a service transmission obtained by the timer, and if the UE does not have a service transmission for a preset duration, The base station unicasts to the UE RRC signaling including an identifier for indicating that the UE performs cell reselection, and the UE is switched from a connected state to a light connected state, that is, the UE starts the cell reselection process without performing a cell handover procedure. When the UE performs the service transmission again based on the service transmission request, the base station instructs the UE to perform the cell handover, and the UE is switched from the light connection state to the connected state, and the base station makes a handover decision according to the measurement report reported by the UE, and according to the The handover decision notifies the UE to switch to a new cell or not to switch, which can reduce signaling generation. Effectively reduce the signaling load of the network and reduce the power consumption of the UE.

FIG. 6 is a schematic flowchart diagram of a fifth embodiment of a method for managing a UE according to an embodiment of the present invention. The management method of the UE described in this embodiment is mainly described from the side of the base station, and includes the following steps:

S601. The base station broadcasts RRC signaling including a first duration, where the RRC signaling including the first duration is used to indicate that the UE starts a timer when the RRC connection is established with the base station based on the service transmission request, and the service transmission ends. The cell reselection is performed according to the cell measurement result when the duration that the UE does not receive the service transmission reaches the first duration.

The mobility management mechanism corresponding to the connection state in the RRC state may be adjusted according to the provisions of the existing 3GPP protocol, that is, the mobility management mechanism combining cell handover and cell reselection is adopted for the UE in the connected state. When the UE is in the connected state, the UE performs the cell reselection process without performing the cell handover procedure when the duration of the service transmission does not reach the preset duration. Otherwise, the cell handover procedure is performed without performing the cell reselection procedure.

Specifically, the base station may periodically notify the UE served by the base station by using a broadcast, and the UE sets the preset duration to the first duration. The UE establishes an RRC connection with the base station based on the service transmission request, and performs service transmission. After the service transmission ends, the UE maintains the RRC connection established with the base station and is always in the connected state. The UE starts the timer at the end of the service transmission. If the timer duration of the timer reaches the preset duration during the period of no service transmission, the UE automatically performs the cell reselection procedure without performing the cell handover procedure.

S602. The eNB unicasts the RRC signaling including the second duration to the UE, when the UE detects that the UE performs the service transmission again according to the service transmission request, where the RRC signaling including the second duration is used to indicate the location. The UE starts a timer at the end of the service transmission, and when the duration of the service that the UE does not receive the service transmission reaches the second duration, the cell reselection is performed according to the cell measurement result.
