Description

Service acceleration method and device

Technical Field

The present invention relates to communications technologies, and in particular, to a method and an apparatus for accelerating a service.

Background

With the development of social economy, urban traffic is more and more convenient, people are more and more common when traveling by means of transportation (such as cars, buses, subways, and the like), and mobile services with high quality of Service (QoS) guarantee requirements are used on the transportation through a network. The high QoS guarantee requirement means that the service transmission requires higher bandwidth and smaller delay requirement. For example, a user watches videos, online games and the like in a moving state, when the user in motion watches videos or online games, a large bandwidth resource needs to be guaranteed for a traffic flow in real time to ensure the fluency of user experience. For a user in a mobile state, the staying time in one cell is usually short, and the user may need to switch multiple cells in a short time, so that the next cell to be switched by the user needs to have enough bandwidth resources to ensure the fluency of the user when using the mobile service with high QoS guarantee requirement.

In the prior art, when a User Equipment (User Equipment, abbreviated as UE) is switched from a serving cell (or called source cell) providing services for the UE to a next cell (target cell) in a mobile line of the UE, the UE measures signal quality of a plurality of target cells and sends a measurement result to the serving cell, and the serving cell interacts with the plurality of target cells to obtain an available resource condition of each target cell. In order to ensure the stability of UE service transmission, the serving cell generally selects a target cell with the best signal quality for handover.

However, after the UE switches to the target cell with the best signal quality, if the target cell has a situation with less available resources, or the target cell is currently in an overload congestion state, the target cell may perform speed reduction processing on the mobile service with the high QoS guarantee requirement of the UE, so that the mobile service with the high QoS guarantee requirement can only use the less available resources of the target cell, and therefore the mobile service with the high QoS guarantee requirement in the mobile state of the UE may be stuck and delayed.

Wherein, performing service acceleration processing on at least one target cell of the UE specifically includes: the strategy and charging entity makes a corresponding QoS strategy according to the network state information of the at least one target cell, and reserves bearing resources for the at least one target cell in advance according to QoS parameters corresponding to the QoS strategy, when UE is switched to the at least one target cell, the mobile service with high QoS guarantee requirement uses the reserved bearing resources in advance, and the reserved bearing resources in advance meet the requirement of the high bandwidth of the mobile service with high QoS guarantee requirement, so the phenomena of blockage and delay of the mobile service with high QoS guarantee requirement can not occur, and the accelerated processing of the service can be realized.

And 102, receiving a service acceleration notification message sent by the policy and charging entity.

Step 103, sending a service acceleration option message to the UE according to the service acceleration notification message.

Step 104, sending the service acceleration request message sent by the UE to the policy and charging entity, so that the policy and charging entity formulates a QoS rule according to the service acceleration request message, the user subscription information, the operator policy, and the network state information of the target cell of the UE.

Specifically, the service acceleration request message includes an identifier of the UE and/or a service acceleration indication and/or an application identifier. It should be noted that, after receiving the service acceleration request message, the policy and charging entity formulates a QoS rule for quality of service, and obtains a QoS parameter by analyzing the QoS rule, and sends the QoS parameter to at least one target cell of the UE, so that the at least one target cell of the UE performs service acceleration processing on the UE according to the QoS parameter. It should be noted that, the Policy and charging entity of the implementation subject in this embodiment actually includes a Policy and Charging Rule Function (PCRF) and a Policy and Charging Enforcement Function (PCEF), so that, in an actual interaction process, the PCRF formulates a QoS Rule and sends the QoS Rule to the PCEF, the PCEF analyzes the QoS Rule to obtain a QoS parameter and modify or establish a dedicated bearer, and then the PCEF sends the QoS parameter to at least one target cell of the UE, so that the at least one target cell of the UE reserves bearer resources in advance according to the QoS parameter.

In the service acceleration method provided in this embodiment, an application server entity determines an identifier of at least one target cell of a UE, and then the application server entity sends the identifier of the at least one target cell of the UE and the identifier of the UE to a policy and charging entity, so that the policy and charging entity obtains network status information of the at least one target cell of the UE according to the identifier of the at least one target cell of the UE and determines to perform service acceleration processing on the at least one target cell of the UE according to the network status information, further, the application server entity receives a service acceleration notification message sent by the policy and charging entity and sends a service acceleration option message to the UE according to the service acceleration notification message, and when the UE determines to perform service acceleration, the UE sends a service acceleration request message to the application server entity, and the application server entity sends the service acceleration request message sent by the UE to the policy and charging entity so that the policy and charging entity makes a QoS rule according to the service acceleration request message, the user subscription information, the operator policy and the network state information of the target cell of the UE. Furthermore, the policy and charging entity issues the QoS parameter in the QoS rule to the target cell of the UE, so that the target cell of the UE reserves the bearer resource in advance according to the QoS parameter in the QoS rule, so that the UE has sufficient available bandwidth when moving to the target cell, and the smoothness of using the mobile service with high QoS guarantee requirement by the user is ensured.

Further, regarding step 100 in fig. 1, one possible implementation manner is:

step 100a, receiving a routing message sent by the UE, where the routing message includes routing information, a destination, and an identifier of the UE.

Specifically, the route information may be route information determined by the user through a map, a navigation system, or the like, and optionally, the route information is represented by, for example, longitude and latitude coordinates of the route selected by the user. The latitude and longitude coordinates of the line can be determined by latitude and longitude coordinates of a plurality of sampling points on the line. The destination may be represented by latitude and longitude coordinates of the destination. Furthermore, the longitude and latitude coordinates can be acquired through a GPS and correspond to the sampling points and the destinations in advance. And the route information may be a navigation route or a public transportation route.

And step 100b, determining a cell identification list corresponding to the line information.

Specifically, one possible implementation manner is to select the identifier of the cell covering the selected line by matching the coordinate information, such as the longitude and latitude coordinates, corresponding to all the cells stored in advance in the application server entity with the coordinate information, such as the longitude and latitude coordinates of the line selected by the user, where the coordinate information corresponding to the cell may be the center longitude and latitude information and the cell radius of each cell, or the boundary sample point longitude and latitude information of each cell. Because each cell has a certain coverage area, several boundary sampling points are selected in advance on the covered boundary according to the coverage area, and the longitude and latitude of the boundary sampling points are used as the corresponding position information of the cell. Furthermore, the longitude and latitude coordinates can be acquired through a GPS and correspond to the boundary sampling points in advance. And generating a cell identification list corresponding to the line information. By searching the cell identifier list corresponding to the line information, the application server entity obtains the identifier which is about to arrive by the UE and includes but is not currently determined in the next target cell, and sends the identifier of the target cell to the policy and charging entity, and the process is executed circularly until the last cell of the cell identifier list. And if the UE has selected the service acceleration processing, the application server entity does not repeatedly push the service acceleration option to the UE.

Step 100c, obtaining the identifier of the serving cell of the UE, and determining the identifier of the target cell of the UE according to the cell identifier list corresponding to the line information and the identifier of the serving cell of the UE.

Preferably, the identifier of the target cell of the UE may be determined according to a cell identifier list corresponding to the line information, the identifier of the serving cell of the UE, and a destination selected by the UE.

Further, for receiving the line message sent by the UE in step 100a, a possible implementation manner includes:

the method I is used for receiving a line message sent by UE.

Specifically, for a vehicle equipped with an onboard GPS, the onboard GPS system does not have a Subscriber Identity Module (SIM) card. After a user inputs a destination in the vehicle-mounted GPS system and the vehicle-mounted GPS system plans a navigation route for the user, the vehicle-mounted GPS system sends route information to the UE in a short-distance Wireless communication mode, such as Bluetooth and Wireless Local Area Network (WLAN). And the UE transmits the line message to the application server entity through the service base station in a short message mode. The application server entity compares the line information with a pre-stored cell distribution diagram of an operator to obtain a cell identification list corresponding to the line information.

For public transport means with fixed lines such as buses, subways and high-speed rails, a line acquisition client is installed on UE (intelligent mobile phones and tablet computers), a user inputs the number of cars and destinations in the line acquisition client, and the client transmits information and identity identification information input by the user to an application server entity through a service base station in a short message mode. The application server entity stores the cell identification list of the operator through which each bus, subway and high-speed rail of each train pass in advance, and calls the cell identification list corresponding to the line information (train number) from the memory after receiving the line (train number) taken by the user sent by the client.

And the second mode is to receive the line message sent by the vehicle-mounted GPS.

Specifically, for a scenario in which the UE uses the service acceleration method provided by the present invention on a vehicle having a vehicle-mounted GPS and an SIM card, the UE may send a line message to an application server entity by using the vehicle-mounted GPS of the vehicle. For vehicles equipped with onboard GPS, the onboard GPS system has a SIM card built in. The User inputs a destination in the vehicle-mounted GPS system, and sends an Identification of a User Equipment (UE) including, but not limited to, an Internet Protocol (IP) address, an International Mobile Subscriber Identity (IMSI), and a Temporary Identity (TMSI) to the vehicle-mounted GPS system through a short-range wireless communication method (such as bluetooth and WLAN). After planning a navigation route for a user, the vehicle-mounted GPS system transmits the route and user identity identification information to an application server entity through a service base station in a short message mode through a built-in SIM card. The application server entity compares the driving route with a pre-stored operator cell distribution map to obtain a cell identification list corresponding to the line information.

Further, for step 100b, one possible implementation manner is:

and determining a cell identification list corresponding to the line information according to the line information and the cell distribution diagram.

The application server entity stores a cell distribution diagram in advance, wherein the cell distribution diagram comprises the identifications of all cells and the position information corresponding to each cell.

Preferably, the location information corresponding to each cell includes, but is not limited to, center longitude and latitude information and cell radius of each cell, or boundary sampling point longitude and latitude information of each cell. Because each cell has a certain coverage area, several boundary sampling points are selected in advance on the covered boundary according to the coverage area, and the longitude and latitude of the boundary sampling points are used as the corresponding position information of the cell.

Further, for obtaining the identifier of the serving cell of the UE in step 100c, one possible implementation manner is as follows:

sending a request message to the policy and charging entity so that the policy and charging entity sends a reply message containing the identity of the serving cell of the UE.

Further, after step 104, the method further includes:

Specifically, after completing a handover from the serving cell to the target cell, the UE sends a handover complete message to the policy and charging entity, and sends the handover complete message to the application server entity. And after receiving the switching completion message, the application server entity starts to repeat the operation to determine the identifier of the next target cell of the UE and judges whether the next target cell of the UE can be accelerated.

Fig. 2 is a flowchart illustrating a service acceleration method provided in the second embodiment of the present invention, and preferably, an execution subject of the second embodiment is a user equipment, where the user equipment includes but is not limited to: mobile phones, tablet computers, etc. Referring to fig. 2, the service acceleration method includes the following steps:

step 200, the UE sends a routing message to the application server entity, where the routing message includes routing information, a destination, and an identifier of the UE.

Step 201, the UE receives a service acceleration option message sent by the application server entity, and determines to perform acceleration processing on a service according to the service acceleration option message.

Specifically, the service acceleration option message includes an acceleration option and a no-more-prompt option, and the user sees the service acceleration option message on an interactive interface of the UE and clicks the acceleration option; otherwise, the user clicks the no-prompt option, the application server entity sends the no-prompt information to the policy and charging entity, and the user is in the no-disturbance state.

Step 202, the UE sends a service acceleration request message to the application server entity, where the service acceleration request message includes an identifier of the UE and/or a service acceleration indication and/or an application identifier.

Step 203, the UE switches to the target cell and performs service acceleration processing through the pre-reserved bearer resource.

In the service acceleration method provided in this embodiment, a line message is sent to an application server entity by a UE, where the line message includes line information, a destination, and an identifier of the UE, the UE receives a service acceleration option message sent by the application server entity, determines to accelerate a service according to the service acceleration option message, and sends a service acceleration request message to the application server entity, where the service acceleration request message includes an identifier of the UE and/or a service acceleration indication and/or an application identifier, and finally the UE switches to a target cell and performs service acceleration processing through a bearer resource reserved in advance, and since the target cell of the UE reserves a bearer resource for the UE in advance according to a QoS parameter in the QoS rule, there is sufficient available bandwidth when the UE moves to the target cell, the fluency of the user using the mobile service with high QoS guarantee requirement is ensured.

Further, for the UE sending the routing message to the application server entity in step 200, a possible implementation manner is as follows:

the first method is as follows: and the UE sends the identification of the UE to a vehicle-mounted GPS so that the vehicle-mounted GPS sends the line message to the application server entity.

Specifically, for a scenario in which the UE uses the service acceleration method provided by the present invention on a vehicle having a vehicle-mounted GPS and an SIM card, the UE may send a line message to an application server entity by using the vehicle-mounted GPS of the vehicle. For vehicles equipped with onboard GPS, the onboard GPS system has a SIM card built in. The user inputs a destination in the vehicle-mounted GPS system, and sends the Identity (including but not limited to an IP address, International Mobile Subscriber Identity (IMSI) and Temporary Identity (TMSI)) of the UE to the vehicle-mounted GPS system through a short-distance wireless communication mode (such as Bluetooth, WLAN and the like). After planning a navigation route for a user, the vehicle-mounted GPS system transmits the route and user identity identification information to an application server entity through a service base station in a short message mode through a built-in SIM card. The application server entity compares the driving route with a pre-stored operator cell distribution map to obtain a cell identification list corresponding to the line information.

The second method comprises the following steps: and the UE receives the route information and the destination sent by the vehicle-mounted GPS.

The UE sends the routing message to the application server entity.

Specifically, for a vehicle equipped with an onboard GPS, the onboard GPS system does not have a built-in SIM card. After a user inputs a destination in the vehicle-mounted GPS system and the vehicle-mounted GPS system plans a navigation route for the user, the vehicle-mounted GPS system sends the route information to the UE through a short-distance wireless communication mode (such as Bluetooth, WLAN and the like). And the UE transmits the line message containing the line information to the application server entity through the service base station in a short message mode. The application server entity compares the line information with a pre-stored cell distribution diagram of an operator to obtain a cell identification list corresponding to the line information.

Preferably, before step 200, the method further comprises:

and the UE sends a service request to the application server entity.

Specifically, when the UE uses a mobile service with high QoS guarantee requirement in high-speed movement, the UE sends a service request to the application server entity. For example, the UE network is online, visits a certain video website and clicks on a certain video.

Step 302, the policy and charging entity receives a service acceleration request message forwarded by the application server entity, and formulates a QoS rule according to the service acceleration request message, user subscription information, an operator policy, and the network state information of at least one target cell of the UE.

Based on the information of the driving route of the vehicle-mounted user, the destination and the identifier of the service cell of the UE, the application server pre-judges the identifier of a target cell which is about to arrive by the UE and is not limited to the next cell, and sends the identifier of the target cell to a policy and charging entity. By calling the network state information of the target cell, the strategy and charging entity makes a decision of pushing service acceleration and implements a corresponding QoS strategy in advance, so that the aim of improving the service experience of the vehicle-mounted user is fulfilled.

Step 303, the policy and charging entity triggers at least one target cell of the UE to reserve bearer resources in advance according to the QoS rules.

It should be noted that, in this embodiment, the policy and charging entity of the executive body actually includes functions of the PCRF and the PCEF, so that, in an actual interaction process, the PCRF formulates the QoS rule and sends the QoS rule to the PCEF, the PCEF analyzes the QoS rule to obtain the QoS parameter and modify or establish the dedicated bearer, and then the PCEF sends the QoS parameter to the at least one target cell of the UE, so that the at least one target cell of the UE reserves the bearer resource in advance according to the QoS parameter.

In the service acceleration method provided in this embodiment, a policy and charging entity determines to perform service acceleration processing on at least one target cell of the UE, and then the policy and charging entity sends a service acceleration option message to the application server entity, and the policy and charging entity receives a service acceleration request message forwarded by the application server entity, formulating a QoS rule according to the service acceleration request message, user subscription information, operator policy and the network state information of at least one target cell of the UE, and finally triggering the at least one target cell of the UE to reserve bearer resources in advance by the policy and charging entity according to the QoS rule, therefore, when the UE moves to the target cell, enough available bandwidth is available, and the fluency of using the mobile service with high QoS guarantee requirement by the user is ensured.

Specifically, the network state information of the at least one target cell of the UE may be load information or an available bandwidth of the at least one target cell of the UE, so that the load information of the at least one target cell of the UE is compared with a first threshold, or the available bandwidth is compared with a second threshold, if the load information is greater than the first threshold, or the available bandwidth is smaller than the second threshold, it indicates that the target cell is in a congestion state at the moment, and after the UE is handed over to the target cell, according to the existing load and available bandwidth, a stuck phenomenon may occur when the UE uses a mobile service with a high QoS guarantee requirement, and therefore, the service needs to be accelerated in the target cell. In order to meet the requirement of acceleration processing, the policy and charging entity makes a new QoS rule according to the service acceleration request message, the user subscription information, the operator policy, and the network state information of at least one target cell of the UE. Preferably, the QoS parameter is Allocation and Retention Priority (ARP). Optionally, the QoS parameter may also be a Guaranteed Bit Rate (GBR) and/or a maximum Bit Rate (maximum Bit Rate, MBR) and/or a quality of service Class Identifier (QoS Class Identifier QoS, QCI).

Preferably, for step 303, one possible implementation manner is:

Fig. 5 is a schematic signaling interaction diagram of a service acceleration method according to a fifth embodiment of the present invention, and as shown in fig. 5, for a vehicle equipped with a vehicle-mounted GPS and a built-in SIM card, the service acceleration method includes the following steps:

step 500, the UE sends a service request to the application server entity.

For example, the in-vehicle UE network is online, visits a certain video website and clicks on a certain video therein.

Step 501, the UE sends the UE identification to the vehicle-mounted GPS.

Specifically, the UE sends the UE identity to the onboard GPS via short-range wireless communication (e.g., bluetooth, WLAN, etc.).

Step 502, the user inputs a destination, and the vehicle-mounted GPS calculates a driving route.

Step 503, the vehicle-mounted GPS sends the line message to the application server entity through the built-in SIM card.

Step 504, the application server entity calculates a cell identifier list corresponding to the line information according to the cell distribution map of the operator and the line information.

Step 505, the application server entity sends a request message to the policy and charging entity.

The request message is used for calling the identifier of the UE serving cell, and the message carries the identifier of the UE.

Step 506, the policy and charging entity sends a reply message to the application server entity.

Specifically, the reply message includes an identifier of a serving cell of the UE.

Step 507, the application server entity pre-judges the identifier of the target cell of the user UE according to the identifier of the serving cell of the UE, the cell identifier list corresponding to the line information, and the destination.

Step 508, the application server entity returns the identity of the UE and the identity of the target cell to the policy and charging entity.

Step 509, the policy and charging entity sends the subscription request of the user switching completion and the network state information request message of requesting the network state information to the target cell.

Specifically, the network status information request message carries a network status information parameter table required to be reported, which includes a cell load condition and an available bandwidth.

Step 510, the base station of the target cell reports network state information to the policy and charging entity, and the network state information includes cell load condition and available bandwidth.

Step 511, the policy and charging entity makes an analysis decision according to the network state information.

If the load of at least one target cell of the UE is greater than the first threshold, or the available bandwidth is smaller than the second threshold, that is, the target cell is in a congested state, and if the service acceleration processing is not performed, the phenomena of stuck and delayed when the UE uses a mobile service with a high QoS guarantee requirement may be caused, so that the acceleration processing needs to be performed on the at least one target cell of the UE. Step 511 is triggered.

Step 512, the policy and charging entity sends a service acceleration notification message to the application server entity.

Step 513, the application server entity sends a service acceleration option message to the UE.

Specifically, the service acceleration option message contains an acceleration option and a no-more-prompt option.

And 514, the UE determines to accelerate the service according to the service acceleration option message.

Specifically, the service acceleration option message includes an acceleration option and a no-more-prompt option, and the user sees the service acceleration option message on an interactive interface of the UE and clicks the service acceleration option; otherwise, if the user clicks the no-prompt option, the application server entity sends the no-prompt information to the PCRF, and the user is in the no-disturbance state.

Specifically, the service acceleration request message includes an identity of the UE, for example, including but not limited to an IP address, TMSI, IMSI, and/or the like of the UE, and/or a service acceleration indication and/or an application identity, see third generation Partnership Project (3rd generation Partnership Project) TS 29.214.

Step 517, the policy and charging entity makes a QoS rule according to the service acceleration request message, the user subscription information, the operator policy, and the network state information of at least one target cell of the UE, and analyzes the QoS rule to obtain a QoS parameter.

In particular, the rules include QoS parameters. Further, the QoS parameter is ARP. The QoS parameters may also be GBR and/or MBR and/or QCI.

Step 519, the policy and charging entity executes the QoS policy, initiates the process of establishing or modifying the dedicated bearer in advance, and sends the QoS parameter preset message of the user, including the bit rate, QCI, and ARP parameters, to the base station of the target cell.

Step 520, the base station of the target cell stores the QoS preset parameter.

Step 521, the serving cell sends a handover request message to the base station of the target cell.

Step 522, the base station of the target cell executes bandwidth reservation operation, and when the UE accesses the target cell, the base station of the target cell establishes a radio bearer according to the preset QoS parameter.

Step 523, the base station of the target cell sends a handover complete message to the policy and charging entity.

Step 524, the policy and charging entity sends a handover complete message to the application server entity.

Step 525, the application server entity obtains the identifier of the next target cell of the UE by searching the cell identifier list corresponding to the line information.

Specifically, the application server entity sends the identifier of the next target cell of the UE to the policy and charging entity. After step 525, go to step 507 until the last cell of the above cell id list is reached. It should be noted that after the step 507 is reached, if the user has selected the service acceleration processing, the service acceleration option message is not repeatedly pushed during the driving process.

If the user driving route is changed in the process, the vehicle-mounted GPS recalculates the driving route, and sends a new route message to the application server entity, then the process goes to step 503. If the target cell of the user calculated by the application server entity has changed in step 507, the application server entity sends an identifier update message of the target cell of the user to the policy and charging entity, and triggers the policy and charging entity to send a deletion instruction message to the original target cell base station to instruct the original target cell base station to delete the preset parameters and release the reserved bandwidth resources.
