Description
Technical Field
The present invention relates to the field of computer and communication technologies, and in particular, to a method and a controller for reducing service latency.
Background
In the existing typical Long Term Evolution (LTE) standard flow, the Quality of Service (QoS) modification can be completed by establishing, modifying and releasing a dedicated bearer.
As shown in fig. 1, dedicated bearer establishment may be actively initiated by a User Equipment (UE) or a Mobility Management Entity (MME), and a base station eNodeB cannot be actively initiated. If the bearer establishment process is initiated by the MME actively, the steps 1 and 2 are omitted; the UE initiates a bearer establishment flow, and a core network can reply the bearer establishment and modification flow; multiple dedicated bearers can be established simultaneously but are not currently supported.
The dedicated bearer modification may be initiated actively by the UE, MME, and not by the eNodeB. The flow of modifying QoS is shown in fig. 2. If the MME actively initiates the bearer establishment/modification/release, the steps 1 and 2 are omitted; if the eNodeB initiates the RELEASE actively, there is no step1, step2 changes to send E-RAB Release INDICATION message to MME; the UE initiates a bearer modification process, and the core network can reply the bearer establishment, modification and release processes. The flow of only modifying the traffic Template (TFT) without modifying the QoS is shown in fig. 3, and is a direct uplink and downlink message, which is independent of the eNodeB.
Dedicated bearer release procedure as shown in fig. 4, dedicated bearer release may be actively initiated by eNodeB, MME.
In the prior art, modification of user service information (the user service information refers to information of a telecommunication service signed by a user and an operator, and may include bandwidth of the telecommunication service used by the user, time of the telecommunication service used by the user, charge of the telecommunication service used by the user, availability of the telecommunication service used by the user, and the like, for example, the operator ensures that the annual interruption time of the service is less than 2 hours) is triggered by a core network, and the core network belongs to a black box in the telecommunication network. In the prior art, the change of service bandwidth is completed from the perspective of QoS and proprietary bearer mainly through interaction of a core network, so that the priority of a user on a wireless side is not supported to be changed in real time externally, and the network capability of a wireless network access side is provided externally. The QoS of a typical service includes: the bandwidth of the telecommunication service of the user, the time delay of the telecommunication service of the user, the availability of the telecommunication service of the user, and the like, so the time delay of the telecommunication service is an index of the QoS. The prior art mainly improves service delay from the perspective of improving telecommunication QoS (for example, when a user access bandwidth is limited, the service delay of the user may be increased, so that the prior art improves the service delay from the perspective of improving the user access bandwidth, and for example, when the route of user service data is blocked, the prior art considers improving from the perspective of optimizing the data packet route).
In the prior art in the telecommunication system, the improvement of the QoS is processed by mapping the QoS strategy from the core network side to the access network, and a complex mapping and conversion process is needed in the middle, so that the real-time performance of the delay improvement is not particularly good. In addition, because the QoS of the telecommunication service is not equal to the QoS of the OTT service used by the user, the time delay of the OTT (over the top, which means that the internet company goes over the telecommunication (telecom) operator to develop various video and data service services based on the open internet, and emphasizes the independence of the service and the physical network) service is not considered in the optimization of the telecommunication service by the operator, and thus the improvement of the service delay of the OTT according to the user requirement cannot be guaranteed.

Detailed Description
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
The invention provides a method for reducing user service delay based on a wireless network architecture of an SDN. The wireless network architecture of such SDN is as follows (the architecture has been disclosed in some patents, and the present invention is described here):
as shown in fig. 5, the wireless network architecture of the SDN includes several important network elements: a wireless controller, a wireless access network, a telecommunication operator charging system, an OTT server and the like.
The controller is a core of the present architecture, and the network element centralizes the control plane capability of the wireless network, including: control of wireless air interface scheduling priority, control of core network routing, scheduling of radio network RB resources, scheduling of radio spectrum resources, and the like.
The controller is used as a core network element of the architecture, and interfaces exist between the controller and other network elements, wherein an OR1 interface is adopted between the controller and a radio access network, an OR2 interface is adopted between the controller and a user terminal, and an OR3 interface is adopted between the controller and an OTT operator/virtual operator. In addition, the architecture also defines a charging interface between the telecom operator and the OTT operator: OR4 interface.
The OR1 interface, which interfaces between the control plane and the data plane of the wireless network, is primarily conventional control plane to data plane control information, including but not limited to: controlling an air interface scheduling priority of the wireless base station; controlling scheduling of RB resources; controlling how the radio base station spectrum is used; controlling data transmission between the wireless base stations; controlling data transmission from the base station to the core network; controlling a scheduling algorithm of the radio base station; controlling the system of the wireless base station; controlling the generation, destruction and the like of the virtual base station;
the OR2 interface, which is used as an interface between the wireless network and the wireless terminal, mainly transfers network control information to the terminal, and the information includes but is not limited to: controlling the system of the wireless terminal, and controlling the wireless spectrum usage (white spectrum usage); controlling the wireless terminal to access to the wireless network (which wireless network the wireless terminal is to access in case of multiple wireless networks); controlling the wireless terminal to generate and destroy the virtual base station; controlling handover of the wireless terminal; the information transmitted by the OR4 interface also includes control information from the wireless terminal to the wireless network, i.e. not only the wireless network control wireless terminal but also the wireless terminal control wireless network via the OR4 interface. Control over the wireless network, particularly over the wireless terminal, is similar to that of the OR3 interface;
an OR3 interface as an interface between the controller and the OTT operator and the virtual operator, through which the OTT operator and the virtual operator can invoke the control capability of the wireless network to control the wireless access network and the wireless core network; these controls include, but are not limited to: controlling the creation and destruction of the wireless virtual base station; controlling data routing from the base station to the core network; controlling a data route from a base station to the RRU; controlling the QoS of the service; controlling the priority of the wireless resource air interface scheduling; control the base station to use wireless spectrum resources (e.g., use white spectrum); controlling interaction between the base station and the spectrum database; controlling charging interaction between the telecommunication charging system and the OTT charging system; controlling the distribution of data streams to various wireless standard networks; controlling the switching of resources between RANs; control the routing of data streams at handover, etc.;
the OR4 interface is an interface between a telecommunications carrier and an OTT carrier, and through this interface, the OTT carrier and the telecommunications carrier perform real-time payment settlement.
The user in the scene based on the above framework has two identities, one identity is a telecommunication user, and the other identity is an OTT user; the user pays for the OTT to use the OTT high-speed channel, thereby using the OTT enhanced service; OTT pays for telecom operators, and telecom operators provide high-speed channels for OTT users to meet the requirements of OTT enhanced services. In this way, win-win results can be brought to telecom operators, OTT operators and users.
Based on the network architecture, the method for reducing service delay of the embodiment of the present invention is shown in fig. 6, and includes:
in step S610, the controller (such as the above-mentioned radio controller) receives a service latency acceleration request initiated by the user equipment UE.
Step S620, the controller adjusts the transmission delay of one or both of the core network and the access network of the UE according to the service delay acceleration request.
Step S630, the controller obtains the adjusted time delay fed back by the UE, and if the adjusted time delay reaches the time delay required by the UE, the adjustment is completed.
Further, the specific way for the controller to receive the service delay acceleration request initiated by the UE in step S610 includes:
the controller receives a request for accelerating the service delay directly initiated by the UE, wherein the request carries the identifier of the UE in a network operator, the service identifier of the UE in the service operator and the required delay information. Or the controller receives a service delay acceleration request of the UE reported by the service operator, wherein the request carries the identity of the network operator where the UE is located, the service identity of the UE in the network operator, the service identity of the service operator in the network operator and the identity of the service operator in the network operator. And after receiving the request reported by the service operator, the controller authenticates the service operator and finds out the service identifier or the bearing identifier of the UE in the network operation according to the information carried in the request.
Further, the specific ways in which the controller adjusts the transmission delay of one or both of the core network and the access network of the UE according to the service delay acceleration request in S620 include the following four ways:
(1) the controller initiates a QoS modification request to a base station eNodeB serving the UE on an access network side of the UE, where the request is used to modify a traffic QoS class of the UE or modify a bearer of the UE. I.e. to reduce traffic delay by modifying the quality of service or the bearer capability.
(2) The controller generates a route forwarding strategy for reducing the service delay so as to control the router to optimize a forwarding path; and the route forwarding strategy is issued to the router positioned in the core network. The method reduces the service delay by optimizing the route and reducing the data transmission time.
(3) The controller initiates a request to a base station eNodeB on the access network side of the UE, instructing the base station eNodeB to increase the scheduling priority for the UE. The method reduces the waiting time of data at the eNodeB by preferentially scheduling the transmission data of the UE, thereby reducing the service delay.
(4) The radio controller instructs the base station eNodeB on the access network side of the UE to reduce retransmission messages to the UE to reduce traffic delay. For example: if a certain message transmitted by the eNodeB to the UE is not responded, the eNodeB will reduce the number of retransmissions of the message to transmit the data that should be currently transmitted, thereby reducing the delay.
In the specific adjustment of the time delay, the adjustment may be performed in one of the specific manners (1) to (4), or may be performed in any combination of the manners (1) to (4), for example: the time delay of the core network and the access network of the UE can be adjusted simultaneously in the manners (1) and (3).
Further, in step S630, the controller may obtain the adjusted time delay fed back by the UE, and may report the adjusted time delay by receiving the UE; or receiving the adjusted time delay reported by the service operator; or the controller acquires the adjusted time delay fed back by the UE by detecting the time delay of the service layer.
After the above steps of adjusting the time delay, the controller obtains the adjusted time delay fed back by the UE, and if the time delay required by the UE is not reached, the step S620 is repeatedly executed, that is, the time delay is adjusted in one or any combination of the above steps (1) to (4) until the time delay required by the UE is reached.
Further, after the adjustment is completed, the method further comprises the following steps: the controller starts service charging, that is, starts an OTT charging system in the OTT server through an OR3 interface in fig. 5 to charge the accelerated service according to a preset charging mode.
The following scenario specifically illustrates the method for reducing service latency according to the present invention.
Bob is a game fan, using the LTE network, and the service rate contracted with the operator is 2 mb/sec.
Saturday is on vacation, and Bob and friends go out for spring travel and go to beautiful Qingcheng mountains for barbecue. On the way, a plurality of friends feel bored and want to play a magic plate together, so that the friends take out the ipad (LTE edition) of the friends and get on a large platform to play games. However, as the number of tourists in the qingcheng mountain scenic area is too many, the people feel large time delay in the process of playing games, and the game experience is not good. At the moment, the operator prompts the user to purchase a 'Gaming Boost' service, and prompts the user to use the service, so that the time delay of the game can be reduced to 10ms, and the real-time effect of game competition is ensured. Bob and friends then purchase the service together. After purchasing the accelerated service, Bob and friends can eventually play Dota smoothly. In this scenario, the user uses the default telecom subscription service, and the satisfactory OTT service experience of the user cannot be guaranteed. The user pays to the OTT service operator, and the OTT service operator negotiates with the telecom operator to divide the OTT service into the OTT service operator, so that the time delay of the service is accelerated for the user, and the user can be ensured to smoothly use the OTT service. The method for realizing the game acceleration is realized by the following specific steps:
based on the network architecture, a first method for reducing game service delay according to the embodiment of the present invention is shown in fig. 7: the method comprises the following steps:
step 1: UE initiates a request to a controller of a wireless controller to request for accelerating the game service; the request carries the identity of the UE in the network operator, the service identity of the game (the service identity of the UE in the service operator) and the accelerated delay information;
step 2: the wireless Controller decides to find the network operation business identifier (or bearer identifier) corresponding to the game service used by the UE according to the two identifiers in step1, and then the wireless Controller initiates a QoS modification request to the eNodeB serving the UE, where the QoS modification request is used to modify the service QoS class of the UE (or modify the bearer of the UE and improve the service delay by modifying the bearer, which needs the basis of the wireless Controller);
step 3: after receiving the request, the eNodeB initiates a request for modifying the bearing context to the UE;
step 4: the UE replies Radio Resource Control (RRC) connection reconfiguration completion after receiving the request;
step 5: the eNodeB replies an Evolved Packet System (EPS) bearer context response to the radio controller;
step 6: UE initiates an EPS bearing context modification receiving request to an eNodeB;
step 7: the eNodeB initiates an EPS bearing context modification acceptance request to a radio controller;
step 8: the UE feeds back the service delay to the wireless controller;
step 9: and the wireless controller judges that the service delay meets the service requirement according to the service delay fed back by the UE, and then starts service charging.
In this embodiment, the feedback of the service delay is completed by reporting the service delay through the UE, and in the actual implementation process, the feedback may also be completed by reporting the service delay through the operator of the game, or by detecting the delay of the service layer by the wireless controller.
Based on the network architecture, a second method for reducing game service delay according to the embodiment of the present invention is shown in fig. 8: the method comprises the following steps:
step 1: UE initiates a request to a controller of a wireless controller to request for accelerating the game service; the request carries the identity of the UE in the network operator and the accelerated delay information. And the controller performs authentication according to the identity of the UE in the network operator.
Step 2: the wireless controller detects that the service delay of the UE does not reach the service delay requirement of the request; the wireless controller generates a relevant router forwarding strategy, and the strategy can control the router to optimize a forwarding path, so that the reduction of service delay is brought;
in this embodiment, the further processing may be performed after the acceleration delay in the first method still does not meet the requirement; namely, step2 in the method replaces the procedure after step9 in the first method.
Step 3: and the wireless controller issues the router forwarding strategy to the corresponding router.
The router referred to in this embodiment may be an Openflow-based router, and thus the corresponding route forwarding policy may be an Openflow-based rule.
Step 4: after receiving the forwarding strategy, the router updates the forwarding table of the router, and when the subsequent router forwards the data packet, the router forwards the data packet according to a new rule.
Step 5: and the UE feeds back the new service time delay to the wireless controller.
In this embodiment, the service delay is collected by using a UE feedback manner, and in actual implementation, the service delay may also be collected by the wireless controller itself or reported by the game server.
Step 6: and after the feedback service delay meets the requirement, the wireless controller starts charging.
Based on the network architecture, a third method for reducing game service delay according to the embodiment of the present invention is shown in fig. 9: the method comprises the following steps:
step 1: the UE initiates a request to a wireless controller to accelerate the game service, wherein the request carries the identity of the UE in a network operator, the service identity of the game and the accelerated delay information. And the controller performs authentication according to the identity of the UE in the network operator.
Step 2: the wireless controller detects that the service delay of the UE does not reach the service delay requirement of the request; the wireless controller reduces the time delay of the network from the point of air interface scheduling by judging;
in the method, steps 2 to 7 can be further processed after the acceleration delay in the first or second method still does not meet the requirement; namely, step2 in the method replaces the procedure after step9 in the first or second method.
Step 3: the radio controller initiates a request to the eNodeB instructing the base station to increase the scheduling priority for the UE.
Step 4: after receiving the request from the radio controller, the eNodeB modifies the scheduling priority of each Transmission Time Interval (TTI) to the air interface of the UE.
Step 5: the eNodeB returns a modify scheduling priority success response to the radio controller.
Step 6: and the UE feeds back the new service time delay to the wireless controller.
In this embodiment, the service delay is collected by using a UE feedback manner, and in actual implementation, the service delay may also be collected by the wireless controller itself or reported by the game server.
Step 7: and after the feedback service delay meets the requirement, the wireless controller starts charging.
Based on the foregoing network architecture, a fourth method for reducing game service delay according to an embodiment of the present invention is shown in fig. 10, and includes:
step 1: UE initiates a request to a controller of a wireless controller to request for accelerating the game service; the request carries the identity of the UE in the network operator, the service identity of the game and the accelerated delay information. And the controller performs authentication according to the identity of the UE in the network operator.
Step 2: the wireless controller detects that the service delay of the UE does not reach the service delay requirement of the request; the radio controller reduces the delay of the network by deciding to reduce Hybrid automatic repeat Request (HARQ) and ARQ (automatic repeat Request) from the air interface perspective.
In this embodiment, steps 2 to 7 may be further processed after the acceleration delay in any of the above methods has not yet been met; namely, the step2 in the method replaces the step9 in any of the above methods.
Step 3: the radio controller instructs the base station to reduce the retransmission messages to the UE.
Step 4: the eNodeB modifies the number of HARQ retransmissions per TTI to the UE.
Step 5: the eNodeB feeds back a modification success response to the radio controller.
Step 6: the UE feeds back the network delay to the wireless controller.
Step 7: and after the feedback service delay meets the requirement, the wireless controller starts charging.
In the four methods for reducing the service delay, it is described that the UE requests the network operator for the delay acceleration, but the method may also be evolved such that the UE requests the game operator for the delay acceleration of the service, and then the game operator requests the radio Controller for the delay acceleration of the specified service of the specified UE. That is, the flow is replaced with the flow shown in fig. 11, so as to explain the flow of the first method. The replacement process comprises:
step 1: the service acceleration request sent by the UE to the game operator needs to carry the identity of the network operator where the UE is located, and the service identity of the game service of the UE in the network operator.
Step 2: the game operator initiates a request to the wireless controller to perform time delay acceleration on the UE, wherein the request carries the identity of the UE in the network operator, the service identity of the game service in the network operator, and the identity of the game operator in the network operator. The service identifier is carried with the service identifier of the service operator at the network operator, and the service identifier is related to the time delay, for example, the predetermined time delay of the video service must be 50ms, and the time delay of the game service must be 10 ms.
Step 3: after receiving the request, the wireless controller authenticates the game operator; and according to the information carried in step2, find out the service identifier or bearer identifier of the UE in the network operation.
After the authentication is passed, the controller reduces the service delay by using any one of the first to fourth methods.
By the method, the user equipment can initiate the request when needed, so that the service delay is reduced.

The delay adjusting unit 1220 specifically adjusts in the following four ways:
(1) the delay adjusting unit 1220 initiates a QoS modification request to the base station eNodeB serving the UE on the access network side of the UE, where the QoS modification request is used to modify the service QoS class of the UE or modify the bearer of the UE.
(2) The delay adjusting unit 1220 generates a routing forwarding policy for reducing service delay to control a router to optimize a forwarding path, and issues the routing forwarding policy to a router in a core network.
(3) The delay adjusting unit 1220 initiates a request to the base station eNodeB located on the access network side of the UE, and instructs the base station eNodeB to increase the scheduling priority of the UE.
(4) The delay adjustment unit 1220 instructs the base station eNodeB located on the access network side of the UE to reduce retransmission messages to the UE.
The delay feedback unit 1230 obtains the adjusted delay fed back by the UE, and if the adjusted delay reaches the delay required by the UE, the adjustment is completed; if the requirement is not met, the information is fed back to the delay adjusting unit 1220 to make it continue to adjust until the requirement is met. The delay feedback unit 1230 is configured to receive the adjusted delay reported by the UE; or receiving the adjusted time delay reported by the service operator; and acquiring the adjusted time delay fed back by the UE by detecting the time delay of the service layer.

Further, the UE is specifically configured to send data carrying an identity and a service identity of the UE in a network operator to the service operator server; the service operator initiates a request carrying the identity of the UE in the network operator, the service identity and the identity of the service operator to the controller; and the controller is used for authenticating the service operator after receiving a request initiated by the service operator, and finding out the operator service identifier corresponding to the service used by the UE according to the identity identifier of the UE in the network operator, the service identifier and the identity identifier of the service operator.
Further, the controller is configured to find, according to the identifier and the service identifier of the UE in the network operator, an operator service identifier or a bearer identifier corresponding to a service used by the UE, and initiate a QoS modification request to a base station eNodeB serving the UE in the radio access network, where the QoS modification request is used to modify a service QoS class of the UE or modify a bearer of the UE; after receiving the request, the eNodeB initiates a request for modifying the bearing context to the UE; the UE replies RRC connection reconfiguration completion after receiving the request; the eNodeB replies an EPS bearing context response to the radio controller; UE initiates an EPS bearing context modification receiving request to an eNodeB; the eNodeB initiates a modify EPS bearer context accept request to the radio controller.
Further, when the controller detects that the service delay of the UE does not meet the requested service delay requirement, the controller generates a router forwarding policy for reducing the service delay and issues the router forwarding policy to a corresponding router; the router is used for updating the forwarding table of the router after receiving the forwarding strategy, and the subsequent router performs routing forwarding according to the strategy when forwarding the data packet.
Further, when the controller detects that the service delay of the UE does not meet the requested service delay requirement, the controller initiates a request to a base station eNodeB in the radio access network to instruct the base station to improve the scheduling priority of the UE; after receiving the request sent by the controller, the eNodeB modifies the air interface scheduling priority of each transmission time interval to the UE, and returns a successful response of modifying the scheduling priority to the controller.
Further, when the controller detects that the service delay of the UE does not meet the requested service delay requirement, the controller instructs the base station eNodeB to reduce the retransmission message for the UE; the eNodeB modifies the HARQ retransmission times of each transmission time interval to the UE; the eNodeB feeds back a modification success response to the controller.
Further, the UE is specifically configured to feed back the adjusted delay to the controller.
Further, the service operator server is specifically configured to feed back the adjusted time delay to the controller.
Further, the controller is specifically configured to acquire the adjusted time delay fed back by the UE by detecting a time delay of a service layer.
