Description

Method and apparatus for controlling on-demand bandwidth services

This application claims priority to Chinese Patent Application No. 201410302141.9, entitled "Method and Apparatus for Controlling On-Demand Bandwidth Services", filed on June 27, 2014, the entire contents of which are incorporated herein by reference. In the application.

Technical field

Embodiments of the present invention relate to the field of communications technologies, and, more particularly, to a method and apparatus for controlling bandwidth on demand services.

Background technique

With the rapid development of the Mobile Broadband (MBB) service, operators hope to strengthen pipeline operations through the opening of network capabilities. Operators can open up network capabilities to third-party application providers.

QoS (Quality of Service) differentiated deployment is a major feature of the MBB pipeline. In particular, after the pipeline is opened to third parties through the MBB network, some temporary bandwidth-on-demand (BoD, Bandwidth on Demand) requirements will appear. For example, the Turbo Button requirement and the OTT Server (Over the Top Server) are used to improve the experience of the subscribers and apply for temporary QoS procedures.

The user's QoS prioritization can be implemented by improving the user's scheduling priority mode, that is, implementing the BoD function. The BoD function does not increase system resources, but only redistributes system resources. If some users are allocated more resources, the resources of other users will be correspondingly reduced, which may seriously affect the quality of service of other users.

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 a part of the embodiments of the present invention, but not all 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.

The technical solution of the present invention can be applied to various communication technologies, such as: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access ( WCDMA (Wideband Code Division Multiple Access Wireless), General Packet Radio Service (GPRS), Long Term Evolution (LTE), and the like.

A User Equipment (UE), which may also be called a Mobile Terminal, a mobile user equipment, or the like, may communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network). The user equipment may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket, handheld, computer built-in or in-vehicle mobile device, The wireless access network exchanges languages and/or data.

The system of FIG. 1 includes a UE 101, a radio access network (RAN) device 102, a core network (CN, Core Network) device 103, and a Policy and Charging Rules Function (PCRF). A User Profile Attribute (SPR) 104, an Enable Open Gateway (also referred to as an Enabler) 105, and an OTT Server 106.

The interface between the CN 103 and the capability open gateway 105 is called a Ge interface, and the interface between the PCRF/SPR 104 and the capability open gateway 105 is called an Rx interface, and the interface between the capability open gateway 105 and the OTT server 106 is called capability open. interface. The interface between the PCRF/SPR 104 and the OTT server 106 is referred to as a user issuance interface. The capability open interface or the user release interface can be converted by the Simple Object Access Protocol (SOAP) interface or performance state transition. (RESTFul, Representational State Transfer) interface implementation.

In the current technical solution, the scheduling priority mode of the user is directly enhanced to implement the BoD function, that is, when the BoD resource needs to be allocated to the UE, the scheduling priority of the UE is directly raised, thereby allocating the BoD resource to the UE. There is no admission control for the BoD service. Specifically, this implementation manner may be defined as two modes, that is, a mode of applying for a BoD resource forward and a mode of applying for a BoD resource backward.

In the mode of forward application BoD resources, an application (App) is installed on the user's UE 101. The application interacts with the OTT server 106. After the user signing is completed by the OTT server 106 to the SPR 104, the QoS update is initiated by the PCRF 104, so that the UE/RAN/CN implements the BoD service function by using the high priority scheduling mode.

In the mode of applying for the BoD resource, the OTT server 106 invokes the SOAP or RESTFul open interface provided by the capability opening gateway 105 to apply for the BoD resource for the user, and the capability opening gateway 105 applies for the BoD resource for the user through the Rx interface.

In any of the foregoing modes, the BoD service directly allocates resources to the UE, and does not perform the admission control on the resource redistribution behavior. The impact of the user's quality of service.

For example, if there are a large number of users applying for BoD in a cell, these users will get better scheduling, and it is impossible to distinguish the relative differentiated experiences of these users, and it will have a serious impact on ordinary users.

For example, if there are many users in a cell and the cell is overloaded (for example, the maximum rate that a user with a good signal can obtain is less than 300 Kbps), if a user applies for a BoD service, the experience of the ordinary user is seriously affected.

For another example, if the user is at the edge of the cell, the signal quality is not good, and the obtained bandwidth is not much; when the whole cell is in congestion, for example, even if the user with better signal can obtain the rate less than 512 Kbps, the user applies for the BoD service. The effect of the promotion may not be obvious, and it will seriously affect the experience of ordinary users.

The embodiment of the present invention provides a BoD admission determination function, which can reasonably allocate BoD resources, so that the experience of the BoD user is improved, and the experience of the ordinary user is not seriously affected.

2 is a schematic flowchart of a method for controlling a BoD service according to an embodiment of the present invention. The method of Figure 2 can be applied to the system architecture of Figure 1.

201. Receive a request message, where the request message is used to request whether the BoD industry is allowed for the UE. Conduct a judgment.

The embodiment of the present invention does not limit the specific form of the request message, and the request message may also be referred to as a trigger message, an indication message, a notification message, or a command message. The request message may be explicit, for example, may include an explicit request field or a request identifier for indicating that the request message is used to request a decision on whether the UE is allowed to perform BoD service; the request message may also be implicit, such as a request. The message is used to notify an event or send a parameter that is used to implicitly request a decision on whether the UE is allowed to conduct BoD services.

Specifically, for example, when a user requests a BoD service from an OTT server by clicking an application on the UE, the UE needs to be allocated a BoD resource. Alternatively, the OTT server may also actively apply for a BoD resource for the UE. At this time, the OTT server may send a request message to the capability opening gateway to request whether the UE is allowed to perform BoD service.

For another example, when a UE that has previously allocated a BoD resource switches during use, it may be necessary to re-allocate the BoD resource for the UE. Or, after the OTT server actively requests the UE to apply for the BoD resource, the UE needs to re-allocate the BoD resource to the UE when the UE performs the handover in the process of using the BoD resource. At this time, the core network may send a notification message to the capability open gateway to notify the capability open gateway that the UE is handed over, and trigger or request the capability open gateway to determine whether the UE is allowed to perform BoD service.

For another example, when the UE that has previously allocated the BoD resource reconnects (for example, the user shuts down and initiates the connection, etc.), the system needs to allocate the BoD resource to the UE. At this time, the core network may send a notification message to the capability open gateway, and notify the capability open gateway that the packet data protocol (PDP, Session Data Protocol) session of the UE or the Evolved Packet System (EPS) is established and triggered. Or request the capability open gateway to decide whether the UE is allowed to perform BoD services.

202. Determine whether a network parameter of a network where the UE is located meets a judgment condition for allowing a BoD service.

Network parameters include network resource parameters. The network resource parameter includes at least one of the following: a parameter for indicating the number of high-priority UEs in the cell where the UE is located, a parameter for indicating a cell status of the cell where the UE is located, and a parameter for indicating a signal quality of the location where the UE is located.

The determining process of determining whether the network parameter of the network where the UE is located meets the decision condition for allowing the BoD service to be performed may also be referred to as a BoD admission decision.

203a: When the network parameter meets the judgment condition, the UE is allowed to perform BoD service. Or,

203b: When the network parameter does not satisfy the judgment condition, the UE is rejected from performing BoD service.

In the embodiment of the present invention, before the UE performs the BoD service, the BoD admission decision is performed based on the network resource parameter, and the BoD service is allowed or denied according to the result of the BoD admission decision, so that the BoD resource can be directly allocated to the user applying for the BoD service. The problem that affects the quality of service of other users, so that the allocation of BoD resources can be more reasonably controlled.

The BoD admission decision can be based on different admission conditions (or decision conditions). There may be multiple access conditions, and multiple access conditions may be independent of each other or may be combined with each other. For example, for mutually independent access conditions, when an access condition is not met, it can be judged as failure (ie, the network parameters do not satisfy the decision condition), and only when all the admission conditions are met, can it be judged as Success (ie network parameters satisfy the decision condition). The mutually agreed admission conditions may have different priorities. If the admission condition A and the admission condition B are combined, and the admission condition A has a higher priority, the admission condition A may be determined as Failure, regardless of whether the admission condition B is satisfied or not, may be judged as successful when both the admission conditions A and B are satisfied, and the failure is still determined when the admission condition A is satisfied but the admission condition B is not satisfied. The combination of the above admission conditions is merely exemplary, and the embodiments of the present invention are not limited to the combination modes exemplified herein.

The network resource parameters are based on the network resource control level. In the BoD admission decision of the embodiment of the present invention, the process of determining whether the network resource parameter satisfies the decision condition may also be referred to as a first type BoD admission decision. The decision condition corresponding to the network resource parameter may be based on the network providing capability setting. For example, the decision condition may include information indicating a range of network resource parameters in a case where the BoD service is allowed in the network where the UE is located, such as an allowable range or an allowable range of the number of high priority UEs, an allowable range of the cell state, or not Allowable range, allowable range of signal quality, or disallowed range. At this time, when determining whether the network resource parameter satisfies the decision condition, it may be determined whether the network resource parameter belongs to a range of network resource parameters in the judgment condition. For example, when the network resource parameter belongs to the range of the network resource parameter, the network resource parameter satisfies the decision condition; or, when the network resource parameter does not belong to the range of the network resource parameter, the network resource parameter does not satisfy the decision condition;

The number of the high-priority UEs in the cell where the UE is located may be the number of users currently using the BoD service in the cell. The network resource parameters required to perform the conditional decision may include values of the number of high priority UEs in the cell in which the UE is located, or may further include a corresponding threshold.

The cell status refers to whether the cell is overloaded, for example, it can be divided into a state of congestion, idleness, and the like. Optionally, the cell status may be represented by a parameter such as a user average rate. For example, when the average user rate under the cell is lower than a certain threshold, the cell may be considered to be in a congested state, that is, overloaded; When the rate is greater than or equal to a certain threshold, the cell may be considered to be in an idle state. However, the embodiment of the present invention does not limit the characterization parameters of the cell state. The network resource parameters required to perform the conditional decision may include a cell status indication value (e.g., 1 indicates idle, 0 indicates congestion/overload) or other type of parameter value (e.g., user average rate), or may further include a corresponding threshold.

The signal quality of the location of the UE refers to the network quality status at the current location of the UE. For example, the channel quality indicator (CQI) or other parameter may be used. The embodiment of the present invention does not limit the characterization parameters of the signal quality. The network resource parameters required to perform the conditional decision may include a signal quality indicator value (eg, 1 indicates better quality, 0 indicates poor quality) or other type of parameter value (such as CQI value), or may further include a corresponding threshold.

Specifically, for example, when considering the number of high-priority UEs in the cell where the UE is located, the number of online BoD users in one cell may affect the normal user experience. Therefore, if the number of high-priority UEs in the cell where the UE is located is equal to or If it is greater than a certain threshold, it may be determined that the network resource parameter does not satisfy the corresponding decision condition.

When the cell status is considered, the upgrade of the ordinary user to the BoD user due to the overload of the cell will result in the deterioration of the normal user experience in the cell. Therefore, if the cell status is overloaded or close to overload, the network resource parameter may be determined. Meet the corresponding judgment conditions.

When considering the signal quality of the location where the UE is located, because the quality of the user network that uses the BoD is poor, even if the user upgrades to the BoD user, the user cannot obtain a good experience and affects the experience of the ordinary user. Therefore, if the signal quality of the location of the UE is poor (for example, the CQI is lower than a certain threshold), it may be determined that the network resource parameter does not satisfy the corresponding decision condition.

Alternatively, the above conditions may be combined. For example, the combination considers the cell state and the signal quality of the location of the UE. At this time, if the cell is congested (the average user rate in the cell is <500 Kbps), and the network quality of the location where the UE is located is poor, it is determined that the network resource parameter does not satisfy the decision condition. If the cell is relatively idle (average rate of users under the cell > 500 Kbps), the signal quality of the location of the UE can be upgraded to a BoD user, and a good experience can be obtained.

Therefore, optionally, as an embodiment, in step 202, it may be determined whether the network resource parameter satisfies a decision condition; wherein, when the network resource parameter satisfies the decision condition, the network parameter satisfies the decision condition; or, when the network resource parameter is not When the decision condition is met, the network parameters do not satisfy the decision condition. In this case, the main body performing the method may be an access network device, a core network device, or a capability open gateway.

Optionally, as another embodiment, the network parameter may further include a network management parameter. Network tube The parameter includes at least one of the following: a parameter used to indicate a radio access technology (RAT) of a cell in which the UE is located, and is used to determine whether a cell where the UE is located is a cell with BoD service capability (ie, determining whether the cell where the UE is located is The parameters located in the BoD service enablement area. That is, the process of determining whether the network management parameter satisfies the decision condition in the embodiment of the present invention may be referred to as a second type BoD admission decision. The decision condition corresponding to the network management parameter may be set based on the operator's operational purpose. For example, the decision condition may include information including a range of network management parameters for indicating that the BoD service is allowed in the network where the UE is located, such as an allowed or disallowed range of the RAT, a BoD service enabled area range, or a BoD service disabled area. Range, etc. At this time, when determining whether the network resource parameter satisfies the decision condition, it may be determined whether the network management parameter belongs to the range of the network management parameter in the judgment condition. For example, when the network management parameter belongs to the scope of the network management parameter, the network management parameter satisfies the decision condition; or, when the network management parameter does not belong to the range of the network management parameter, the network management parameter does not satisfy the decision condition;

For example, when considering the RAT, whether the condition is satisfied may be determined according to the RAT type to which the UE is currently attached. For example, only the BoD service can be used in the LTE network. If the network currently attached to the UE is a 2G or 3G network, the network management parameter is considered not to satisfy the RAT condition. The network management parameters required to perform the conditional decision may include information of the RAT to which the UE is currently attached, or may further include information that allows the use or prohibition of the RAT using the BoD service.

For example, when considering the BoD service enablement area, whether the condition is met may be determined according to whether the current location of the UE is in the BoD service enablement area. The manufacturer or the carrier can perform the sub-area deployment. The BoD service is allowed to be used only in some areas. The area can be called the BoD service enable area. Alternatively, the BoD service can be disabled in some areas. This area can be called BoD. Business disabled area. Only the UE can use the BoD service in the BoD service enablement area. Otherwise, the network management parameters are not satisfied with the BoD service enablement area. The network management parameter required to perform the conditional decision may include a parameter indicating the current location of the UE (for example, the cell identifier of the cell where the UE is located), or may further include information of the BoD service enablement area or the BOD service disabled area (for example, the BoD service is enabled). The cell ID set of the cell covered by the zone or the BoD service disabled zone).

Optionally, as another embodiment, the first type of BoD admission decision is a mandatory configuration, and the second type of BoD admission decision is an optional configuration.

In the embodiment of the present invention, when the network parameter includes the network management parameter and the network resource parameter, that is, when the first type of BoD admission decision and the second type of BoD admission decision are configured, when any type of admission decision fails, Determining that the entire BoD admission decision fails, that is, the network parameters do not satisfy the judgment condition. At this time, another type of admission decision may or may not be performed; or, when both types of admission decisions are successful, it is determined that the entire BoD admission decision is successful, that is, the network parameters satisfy the decision condition.

For example, as an embodiment, when it is determined in step 202 whether the network parameter of the network where the UE is located meets the decision condition for allowing the BoD service, whether the network management parameter satisfies the judgment condition may be determined; wherein, when the network management parameter is not When the decision condition is met, the network parameters do not satisfy the decision condition.

For example, as an embodiment, when it is determined in step 202 whether the network parameter of the network where the UE is located meets the decision condition for allowing the BoD service, whether the network resource parameter satisfies the judgment condition may be determined; wherein, when the network resource parameter is not When the decision condition is met, the network parameters do not satisfy the decision condition.

For example, as an embodiment, when it is determined in step 202 whether the network parameter of the network where the UE is located meets the decision condition for allowing the BoD service, whether the network management parameter satisfies the judgment condition, and whether the network resource parameter satisfies the judgment may be determined. condition. When the network management parameter satisfies the decision condition and the network resource parameter satisfies the decision condition, the network parameter satisfies the decision condition.

In addition, BoD admission decisions can be implemented in different deployment methods. For example, it can be divided into a unified judgment method and a hierarchical judgment method.

In the unified judgment mode, the first type of BoD admission decision and the second type of admission decision can be performed on the same device. The device may be an access network device, a core network device, or a capability open gateway.

In the hierarchical decision mode, the first type of BoD admission decision and the second type of admission decision can be performed on different devices. For example, the first type of BoD admission decision is performed on the access network device, and the second type of admission decision is performed on the capability open gateway; for example, the first type of BoD admission decision is performed on the access network device, and the second type The admission decision is performed on the core network device; for example, the first type of BoD admission decision is performed on the core network device, and the second type of BoD admission decision is performed on the capability open gateway; different BoD admissions are performed on different devices. There are still many ways to decide, and there are no restrictions here.

The following two examples are suggested in the embodiment of the present invention:

For example, in a unified decision mode, the capability open gateway may obtain a decision from an access network device (represented by the RAN in the drawings of the present application) or a core network device (represented by CN in the drawing of the present application). The required network parameters are completed and the decision is completed on the capability open gateway.

For example, in the hierarchical decision mode, the first type of BoD admission decision can be performed first on the RAN side. And the result of the decision is notified to the capability open gateway, and then the capability opening gateway comprehensively determines whether the entire BoD admission decision is successful based on the result of the decision and/or the result of the second type BoD admission decision. For example, assuming that the result of the first type of BoD admission decision performed at the RAN is a failure, the capability open gateway can directly determine that the entire BoD admission decision fails without performing the second type of BoD admission decision; If the result of the first type of BoD admission decision is successful, the capability open gateway can continue to perform the second type of BoD admission decision, and determine that the entire BoD admission decision is successful when the second type of BoD admission decision is successful, in the second When the BoD-like admission decision fails, the entire BoD admission decision is determined to fail.

The above decision mode is merely exemplary. For example, the execution subject of the hierarchical decision or the unified decision may be modified, and such modifications still fall within the scope of the embodiments of the present invention.

Optionally, as an embodiment, the capability opening gateway may obtain network resource parameters from a core network device or an access network device.

Optionally, as another embodiment, when determining, by the access network device, whether the network resource parameter meets the determining condition, the access network device may send the resource determination result to the capability opening gateway or the core network device. The result of the resource decision is a result of determining whether the network resource parameter satisfies the decision condition, for example, indicating whether the first type of BoD admission decision executed at the access network device succeeds or fails.

Optionally, as another embodiment, the access network device may send a GPRS (General Packet Radio Service) Tunneling Protocol-User plane (GTP-U) extension header to the core network device. The GTP-U extension header may include the resource decision result described above.

Optionally, as another embodiment, when the capability opening gateway determines whether the network management parameter satisfies the decision condition, the capability opening gateway may acquire the network management parameter from the access network device or the core network device. For example, the GTP-U extension header sent by the access network device to the core network device may further include a cell identifier of a cell where the UE is located, as a network management parameter.

Optionally, as another embodiment, the core network device may further send a cell identifier to the capability open gateway, and/or information of the RAT to which the UE is attached. The cell identity and the information of the RAT to which the UE is attached may be used as a network management parameter.

Optionally, as another embodiment, the first type of BoD admission decision and/or the second type of BoD admission decision may be performed at the access network device. For example, when it is determined by the access network device whether the network management parameter satisfies the decision condition, the access network device may send a management decision result to the capability open gateway or the core network device; wherein, the management decision result is to determine whether the network management parameter satisfies the decision condition Knot fruit.

Optionally, as another embodiment, in step 201, the capability opening gateway may send a first request message for requesting a BoD admission decision to the core network device. The core network device may send a GTP-U extension header carrying the BoD admission request to the access network device based on the first request message. Here, the function of the first request message may be different depending on the decision mode. For example, if the layered decision is made, the first request message may trigger the core network device to request the access network device to perform the first type of BoD admission decision, and request the access network device and the core network device to sequentially return the first type of BoD admission. As a result of the decision, if the second type of BoD admission decision needs to be performed, the access network device and the core network device may be requested to return the condition parameters required for the second type BoD admission decision, respectively. As another embodiment, if a unified decision is made, the first request message may trigger a condition parameter required by the core network device and the subsequent access network device to return the first type and the second type of BoD admission decision, respectively.

Optionally, as another embodiment, before the capability opening gateway sends the first request message for requesting the BoD admission decision to the core network device, the capability opening gateway may further receive, from the OTT server, a second for requesting the BoD resource. A request message or a third request message for requesting a BoD admission decision.

The names of the foregoing first request message, the second request message, and the third request message are merely exemplary, and the embodiment of the present invention does not limit this.

Optionally, as another embodiment, the capability opening gateway may further notify the OTT server of the decision result of the BoD admission decision, and at this time, the OTT server performs steps 202 and 203 according to the decision result of the BoD admission decision. Alternatively, the capability opening gateway sends a notification message to the OTT server that allows or denies the UE to perform the BoD service. At this time, both steps 202 and 203 are performed at the capability opening gateway.

The embodiment of the present invention does not limit the timing of executing the BoD admission decision. For example, optionally, as another embodiment, before or after step 201, it may be determined that the OTT server applies for a BoD resource for the UE; or, it may be determined that the UE has a handover, where the UE has subscribed to the BoD service or has been assigned a BoD. The resource may be determined. The PDP session or the EPS default bearer setup of the UE may be determined. The UE has subscribed to the BoD service.

Specifically, as an embodiment, the BoD admission decision may be performed for the UE when the UE that has applied for the BoD resource has a handover or needs to re-apply for the BoD resource. For example, when the UE has previously applied for the BoD resource, the link is interrupted during use (such as the user turns off the data service switch of the UE, shuts down or powers down, etc.), and may need to re-enter the system when the link is established again. Applying for the BoD resource, the BoD admission decision can be performed for the UE at this time.

Optionally, as another embodiment, after refusing to allocate the BoD resource to the UE due to the failure of the decision result of the BoD admission decision, the OTT server may send a freeze message to the SPR, where the freeze message is used to indicate that the SPR freezes the BoD of the UE. business. Alternatively, the OTT server can release the BoD resource. Alternatively, the OTT server may restore the normal scheduling priority of the UE.

The embodiment of the present invention does not limit the manner in which the UE is allowed to perform the BoD service or the specific mode in which the UE is denied the BoD service.

For example, optionally, as an embodiment, when the request message of step 201 is sent by the OTT server, if the UE is allowed to perform BoD service, the OTT server may sign the BoD service for the UE.

Optionally, as another embodiment, when it is determined that the OTT server requests the BoD resource for the UE, if the UE is allowed to perform the BoD service, the capability opening gateway may request to allocate the BoD resource to the UE.

Optionally, as another embodiment, when the UE has subscribed to the BoD service, if the UE is denied the BoD service, the BoD service of the UE may be frozen. Alternatively, when the UE has been allocated a BoD resource, if the UE is denied the BoD service, the BoD resource allocated to the UE may be released.

After obtaining the result of the first type of BoD admission decision (the result of the resource decision), the resource decision result is carried in the uplink GTP-U extension header and sent to the core network device. At the same time, network management parameters can be carried in the uplink GTP-U extension header. The network management parameter may include a cell identity of a cell in which the UE is located.

307. The core network device returns the resource decision result and the cell identifier to the capability open gateway through the Ge interface, and sends another network management parameter, that is, the information of the RAT to which the UE is attached, to the capability open gateway.

308. If the first type of BoD admission decision is successful (that is, the network resource parameter satisfies the corresponding decision condition), the capability opening gateway performs the second type of BoD admission decision. If the second type of BoD admission decision is successful, the BoD admission result is successful (ie, the network parameter is determined to satisfy the decision condition); if the second type of BoD admission fails, the BoD admission result is a failure (ie, the network parameter does not satisfy the decision) condition). The capability open gateway sends the BoD admission result to the OTT server.

According to the BoD admission result returned by the capability opening gateway, the OTT server performs different operations 309-1 or 309-2.

309-1, if the admission result is a failure, the OTT server refuses to allocate a BoD resource to the UE, and returns a message indicating that the application for the BoD service fails. Of course, the OTT server may not return any message to the UE, and the UE determines that the application for the BoD service fails after receiving the feedback message for a period of time.

309-2, if the admission result is successful, the OTT server allows the BoD resource to be allocated to the UE, and continues to the SPR to subscribe to the BoD service for the user.

310. The SPR responds to the OTT server and signs a BoD service for the user.

311. The OTT server returns an application BoD service result to the UE.
