Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for offloading service data.
Background
At present, the access modes of internal networks or local area networks of places such as enterprises, shopping malls, schools, airports and the like are all WiFi (wireless fidelity) or wireless DDN (Digital Data Network) modes. WiFi needs to deploy a large number of WiFi APs (wireless network switches) in the planned coverage area such as the building, campus, etc. of the enterprise or the mall, and access the WiFi by manually setting the password or by using an intranet authentication method. In the wireless DDN method, a user terminal and a Subscriber Identity Module (SIM) card are required to set an Access Point Name (APN) dedicated to an enterprise, and a dedicated channel is configured by an operator to Access an internal network of the enterprise.
The WiFi is limited by the technical standard design, the transmission power is low, a perfect power control and user scheduling mechanism is not provided, and continuous mobile switching among a plurality of WiFi is not supported. Therefore, WiFi is mostly used in indoor coverage in a small area, and cannot meet the requirements in the scenes of a large number of users, a wide coverage area, the requirement of terminal users for movement, high requirement on user speed, and the like. On the other hand, Wifi only performs authentication by suggesting a password or a verification code because of no user SIM card authentication mechanism in the aspect of security, and thus has security loopholes. In addition, the operation experience of searching for SSID (Service Set Identifier), inputting passwords, and the like is also poor, and the user cannot perceive nothing.
The wireless DDN method requires the use of a dedicated APN, a dedicated SIM card, and a special terminal configuration, which is very inconvenient for users carrying their own mobile terminal devices, and also makes it impossible for enterprises or manufacturers to service other common terminal users than the special terminals. And the related service delay and bandwidth rate are limited by the bandwidth of the private line, so that the user experience is greatly limited.
In the process of implementing the embodiment of the invention, the inventor finds that the existing method for processing the service of the terminal equipment by the WiFi or DDN mode has poor safety and troublesome operation, and on the other hand, the time delay and the speed for processing the service of the terminal equipment by the traditional communication network are large.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a method for offloading service data provided in this embodiment. Referring to fig. 1, the method includes:
101: acquiring terminal information of a preset terminal, service data information corresponding to a service initiated by the preset terminal, and current resource occupation information of a target network generated by shunting service data to a preset network;
102: judging whether the target network is adopted to process the service or not according to the terminal information, the service data information and the resource occupation information, and if so, adopting the target network to process the service;
the terminal information at least comprises a service configuration file identifier, a first priority for establishing a radio bearer between the preset terminal and the target network, and a second priority for allocating resources for the preset terminal by the target network; the service data information at least comprises an IP address of the service data, a service type of the service and a QCI index for processing the service; the resource occupation information at least comprises the current bandwidth resource occupation rate of the target network.
The method for distributing the service data is used for distributing the service data of the existing preset network which has a longer communication link and is used for processing all services, generating the target network which is only used for processing a certain class of services in a certain range, and then adopting the target network to process the services of the preset terminal when the services processed by the preset terminal are judged to meet the preset conditions. For example, a service data offloading device is installed between a radio base station and a core network (a pre-set network), and a local service platform (a target network) for processing a specific service within a certain range is offloaded from a network formed by the radio base station. Compared with the preset network, the target network has a shorter communication link for processing the service, so that the time delay for processing the service by adopting the target network is low and the speed is high. On the other hand, when the preset terminal and the service processed by the preset terminal meet the conditions, the service can be processed by adopting the target network, the target network and the preset network are automatically switched, identity verification is not required, and the operation is convenient.
It should be noted that the preset terminal refers to a mobile phone, a computer, or other terminal equipment. The service initiated by the preset terminal can be a voice service, a video service, a data content access service and the like initiated by the preset terminal. The service data information is information of data related to the service, for example, voice service data information, including a source IP (protocol for interconnection between networks) address, a destination IP address, a service type of the voice service, and a QCI index, such as a minimum rate, a delay, etc., that needs to be guaranteed for processing the service. The resource occupancy information may be, for example, an occupancy of a bandwidth of a data transmission to the target network. The radio bearer refers to a channel of radio communication, and allocates resources to a preset terminal, that is, allocates a bandwidth to the preset terminal. For example, a first priority for establishing a radio bearer is defined by ARP (address resolution protocol), and a second priority for allocating resources to a preset terminal is defined by QCI.
In a specific embodiment, how to determine that the service needs to be processed through the target network according to the parameters may be set according to actual needs, which is not specifically limited in this embodiment.
The embodiment provides a method for distributing service data, which judges whether a target network generated by distributing service data to a preset network can be used for processing a service of a terminal according to information of the terminal and service information to be processed by the terminal. Conventional provisioning networks typically process corresponding traffic over relatively long communication links, with long delays and low speeds. The target network generated by shunting the service data to the preset network is only used for processing specific services, such as local services, in a certain area range, and a communication link for processing the services is shorter than that of the preset network, so that the time delay is low and the speed is high. On the other hand, as the target network performs service data distribution generation on the preset network, when the preset terminal and the service to be processed by the preset terminal meet the preset condition, the target network is automatically adopted to process the service, identity verification is not required, and the operation is simple.
Further, on the basis of the foregoing embodiment, the determining whether to process the service by using the target network according to the terminal information, the service data information, and the resource occupation information includes:
and judging whether the preset terminal has the authority of processing the service by adopting the target network or not according to the identification information stored in the service configuration file identifier, and if so, judging whether the service is processed by adopting the target network or not according to the service data information and the resource occupation information.
It should be noted that the SPID, which is the identifier of the service profile, is a number used by the service provider to define a service subscribed by an ISDN (circuit switched network system) device user, and after obtaining the SPID of the preset terminal, according to a pre-stored correspondence between the terminal and the service, it is determined whether the preset terminal has an authority to process the service using the target network, for example, it is determined whether the terminal has an authority to process the service using the target network according to the SPID of the terminal.
In the method provided by this embodiment, terminals having the authority to process services using the target network are screened out according to the SPID of the preset terminal, and for the services initiated by these terminals, further determination is made as to whether the services can be processed using the target network according to the service data information and the resource occupation information of the target network. The terminal without the authority of adopting the target network to process the service is removed through the SPID, and the speed of the subsequent judgment process is improved.
Further, on the basis of the foregoing embodiments, the determining whether to process the service by using the target network according to the service data information and the resource occupation information includes:
judging whether the target network is adopted to process the service according to the IP address of the service data, if so, judging whether the target network supports the service type according to the service type, and if not, adopting the preset network to process the service;
if the target network supports the service type, judging whether the target network can be adopted to process the service according to QCI index information corresponding to the service processing, and if so, judging whether the target network is adopted to process the service according to the resource occupation information.
For example, if the destination IP address of the service data is a preset network (core network), the service data is directly routed to the core network, and if the destination IP address of the service data is a target network (local service platform), whether to process the service by using the target network is determined according to other information of the service data and the resource occupation condition of the current target network.
For example, after the destination IP address of the service data is determined to be the target network, whether the target network can process the service of the type is determined according to the service type of the service. For example, the service type of the service is a voice service, if it is determined that the target network cannot process the voice service, the service data is directly routed to the preset network, and if it is determined that the target network can process the voice service, QCI index information related to processing the service in the service data information is acquired, and whether the target network is used to process the service and can meet the corresponding QCI index requirement is determined. The QCI index includes requirements such as packet loss rate, minimum guaranteed rate, time delay, etc. for data processing, if it is determined that the corresponding QCI index requirements cannot be met by adopting the target network processing, the service data is directly routed to the preset network, otherwise, it is determined whether to adopt the target network to process the service according to the resource occupation information of the current target network.
In the method provided in this embodiment, further for a service initiated by a terminal having a permission to process the service of the preset terminal by using the target network, further screening is performed according to information of service data, the service that cannot be processed by the target network or the service that cannot meet the requirement of the corresponding QCI index is directly routed to the preset network for processing by using the target network, and the speed of the screened service processed by using the target network is ensured on the service type and the QCI index.
Further, on the basis of the foregoing embodiments, the determining whether to process the service by using the target network according to the resource occupation information includes:
and judging whether the current bandwidth resource occupancy rate of the target network exceeds a preset bandwidth resource occupancy rate, if so, establishing a radio bearer between the preset terminal and the target network according to the first priority, and distributing resources for the preset terminal according to the second priority, otherwise, processing the service by adopting the target network.
It can be understood that the higher the bandwidth resource occupancy rate, the larger the traffic volume currently being processed by the target network is, and the less the traffic volume can be reprocessed. The preset bandwidth resource occupancy is a preset value. When the current bandwidth resource occupancy rate of the target network exceeds the preset bandwidth resource occupancy rate, the services which can be processed by the target network are limited, at the moment, the radio bearer is established according to the establishment corresponding to the preset terminal and the first priority of the radio bearer of the target network, and the resources are allocated to the corresponding services according to the second priority of the resources allocated to the preset terminal.
For example, the radio bearer is established according to a first priority of the radio bearer between the establishment and the target network defined in the ARP, the higher the priority, the first the radio bearer is established, and the lower the priority, the later the radio bearer is established. And then, for the second priority of resource allocation in the QCI, preferentially allocating resources to the terminal with higher second priority, which allocates resources to the preset terminal in the QCI, wherein it can be understood that if the resources with lower second priority are not allocated to the resources, the preset network can be used to process the services of the terminals with lower second priority.
Of course, if the current bandwidth resource occupancy rate of the target network does not exceed the preset bandwidth resource occupancy rate, the target network is directly adopted to process the service of the preset terminal.
The embodiment provides a method for establishing a radio bearer for processing a preset terminal service according to a preset judgment method related to the bandwidth resource occupancy rate of a target network for a service of a preset terminal processed by the target network, which is screened out according to the bandwidth resource occupancy rate. The method aims at the service of a preset terminal, establishes a corresponding wireless bearer according to the service bearing capacity of a target network, allocates resources and ensures the quality of the service processed by the target network.
Further, on the basis of the foregoing embodiments, the acquiring terminal information of a preset terminal, service data information corresponding to a service initiated by the preset terminal, and current resource occupation information of a target network generated by performing service data offloading on a preset network includes:
and judging whether the preset terminal is currently in the coverage range of the target network, if so, acquiring terminal information of the preset terminal, service data information corresponding to a service initiated by the preset terminal, and current resource occupation information of the target network generated by shunting service data to the preset network.
Before the service of the preset terminal is processed by using the target network, the network coverage of the preset terminal may be determined, for example, the network coverage of the terminal is determined according to the position information reported by the terminal. And when the terminal is judged to be in the coverage range of the target network, judging whether the service is processed by the target network.
As a specific embodiment, as shown in fig. 2, a local service data offloading device 203 is adopted to offload service data of a conventional core network for communication (the core network and the external device 202 in fig. 2 are conventional networks for communication, that is, preset networks in the foregoing embodiments), so as to obtain a local service platform 201 (target network) for processing some services in a certain area. As can be seen from fig. 2, a set of traffic data offloading equipment is added to the S1 interface (S1 interface is a communication interface between the base station and the core network) links of the base station and the core network, and both the uplink S1 control plane and the user plane information route pass through the equipment. One end of the service data distribution device is connected with the base station, the other end of the service data distribution device is connected to the core network through the access device, and the other interface of the service data distribution device is connected to a local service platform (for example, the local service platform can be used as a device such as an enterprise intranet, a private cloud or a local service platform and a firewall) as an information transmission path for distributing the local service to the local intranet or the service platform. It can be understood that the local service data offloading device 203 may be disposed at the base station side, may be separately disposed, or may be disposed at the access device side, as long as the service data offloading can be performed on a preset network, and the embodiment is not particularly limited.
In the process of performing service offloading through the local service data offloading device, as shown in fig. 3, first, service data of a terminal reaches the service data offloading device through a radio base station and an ereb (evolved radio bearer) bearer of the terminal, and then, acquires ereb information (e.g., QCI, ARP, SPID, etc.) and an IP address (e.g., including a source address, a destination address, an address version type, etc.) of a user;
then, according to a preset determination rule, the transmission of the service data is determined, for example, whether the terminal or the service has the authority to access the local service platform is determined through the SPID and the IP address (i.e., rule screening of the IP access authority in fig. 3), if so, how to process the service data is further determined, and if it is determined that the terminal or the service does not have the authority to access the local service platform through the SPID and the IP address, the service data related to the terminal or the service data is directly sent to a preset network (e.g., a communication link formed by the core network and the internet in fig. 3). As shown in fig. 3, if it is determined that the terminal or the service has the right to access the local service platform through the SPID and the IP address, it is further determined whether to process the service using the local service platform according to the QCI and the ARP related to the service.
It can be understood that, for different service needs, the specific setting of the determination rule for determining according to the parameters such as SPID, IP, QCI, and ARP may be used, and the specific determination rule is not limited in this embodiment. For example, if a service demander proposes a new service requirement, an operator may design and adjust a distribution rule through the distribution rule control module to satisfy a new service scheme.
As shown in fig. 4, in a specific embodiment, after detecting that the terminal is in the coverage area of the intranet, it is determined whether the user has the authority to access the intranet according to the SPID of the terminal (for example, different terminals are ranked by SPID, and are classified into a general user who cannot access the intranet and a member user who can access the intranet, and at the same time, the member user is classified into a service which can only process the low QCI requirement through the intranet, and a service which can process the high QCI requirement through the intranet). In this step, only the terminal capable of using the intranet processing service needs to be screened out.
And then after the terminal initiates a voice service, judging whether the destination address of the voice service is an enterprise intranet or a core network, if so, directly processing the service through the core network, if so, further judging whether the enterprise intranet supports the service according to the service type (voice service) and QCI (quaternary Committee identifier) of the voice service, if not, directly processing the service by adopting the core network, and if so, correspondingly judging the service according to whether the bandwidth resource utilization rate occupied by the service processed by the current enterprise intranet exceeds the preset bandwidth resource utilization rate.
When the utilization rate of the bandwidth occupied by the service processed by the current intranet exceeds the preset bandwidth resource utilization rate, the priority of the radio bearer is established in the ARP corresponding to the terminal and the priority of the resource distributed to the voice service specified in the QCI is established, the service with high priority is processed by adopting the intranet priority, and corresponding QOS (quality of service) guarantee is provided. And when the bandwidth resource utilization rate occupied by the service processed by the current intranet does not exceed the preset bandwidth resource utilization rate, processing the voice service by adopting the intranet.
In general, the filtering rule provided by this embodiment includes the following two parts: firstly, rule screening based on IP and access right, and using parameters such as SPID and IP as screening rules of user service data distribution. The SPID defines ID information of each UE (user), a network can distinguish UE identities through the SPID, different operation strategies are defined for each UE, the SPID is pre-stored in the equipment to distinguish the level of local service data distribution of different users, and the users with different levels correspond to different service types and access rights to a local service platform. The IP address defines a source address and a destination address of the data packet, and a screening rule for shunting is performed based on a source network or host address, a destination network or host address, and an IP protocol version. If the IP destination address of the user data packet is the address of the local service server, the data packet is routed to the local server, otherwise, the core network is accessed.
And secondly, screening based on local service types and rules of resource occupation control. Using parameters such as ARP and QCI as a screening rule of the wireless network resource occupation amount of the local shunting service; ARP defines the priority of UE radio bearer establishment, and the bearer with high priority can preferentially obtain resources to establish radio bearer when accessing the network; the QCI defines the priority of the UE radio bearer, that is, defines the QoS requirements of the established radio bearer, including priority, maximum/minimum guaranteed rate, delay guarantee, and the like; determining the service type and QoS requirement of the terminal through QCI, and if the service type and QoS local network initiated by the terminal are not supported, directly interrupting the establishment of service connection; meanwhile, when the base station traffic is large, the wireless resource load is too high, the local shunt function is limited, the traffic is limited according to the maximum occupied bandwidth of each type of traffic agreed in advance or the local traffic signed by each traffic demand party in advance, and the traffic with the low priority of ARP and QCI is limited to be accessed to the local shunt network or even is refused to be accessed.
The judging method can cover factors such as user ID, bearing priority, QoS requirement, service type, IP data packet source and destination and the like, and can meet various application scenes.
On the other hand, the present invention also provides a device 500 for offloading service data, which includes an obtaining module 501 and a determining module 502, wherein,

The apparatus 500 for service data offloading provided in this embodiment is suitable for the method for service data offloading described in the foregoing embodiment, and is not described herein again.
The invention provides a device for distributing service data, which judges whether a target network generated by distributing the service data to a preset network can be used for processing the service of a terminal or not according to the information of the terminal and the service information to be processed by the terminal. Conventional provisioning networks typically process corresponding traffic over relatively long communication links, with long delays and low speeds. The target network generated by shunting the service data to the preset network is only used for processing specific services, such as local services, in a certain area range, and a communication link for processing the services is shorter than that of the preset network, so that the time delay is low and the speed is high. On the other hand, as the target network performs service data distribution generation on the preset network, when the preset terminal and the service to be processed by the preset terminal meet the preset condition, the target network is automatically adopted to process the service, identity verification is not required, and the operation is simple.
Further, on the basis of the foregoing embodiment, when determining whether to process the service using the target network according to the terminal information, the service data information, and the resource occupation information, the determining module determines whether the preset terminal has the right to process the service using the target network according to the identification information stored in the service profile identifier, and if so, determines whether to process the service using the target network according to the service data information and the resource occupation information.
Further, on the basis of the foregoing embodiments, when determining whether to process the service using the target network according to the service data information and the resource occupation information, the determining module determines whether to process the service using the target network according to an IP address of the service data, if so, determines whether the target network supports the service type according to the service type, and otherwise, processes the service using the preset network; if the target network supports the service type, judging whether the target network can be adopted to process the service according to QCI index information corresponding to the service processing, and if so, judging whether the target network is adopted to process the service according to the resource occupation information.
Further, on the basis of the foregoing embodiments, when determining whether to process the service using the target network according to the resource occupancy information, the determining module determines whether the current bandwidth resource occupancy rate of the target network exceeds a preset bandwidth resource occupancy rate, if so, establishes a radio bearer between the preset terminal and the target network according to the first priority, and allocates resources to the preset terminal according to the second priority, otherwise, processes the service using the target network.
Further, on the basis of the foregoing embodiments, the obtaining module is further configured to determine whether the preset terminal is currently located in the coverage area of the target network, and if so, obtain terminal information of the preset terminal, service data information corresponding to a service initiated by the preset terminal, and current resource occupation information of the target network, which is generated by performing service data offloading on the preset network.
