Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Fig. 1 is a flowchart of a method for implementing QoS management of a wireless network according to the present invention, as shown in fig. 1, including:

step 100: QoS resource information which can be utilized by the wireless network, service types transmitted by the equipment through the wireless network and QoS resource information which is actually used by the equipment are obtained. In particular, the amount of the solvent to be used,

on one hand, information on a wireless base station and a core network such as a GPRS service support node/mobile management entity (SGSN/MME) is collected, wireless network bearing capacity is determined, and surplus and idle available QoS resource information of the wireless network is analyzed and extracted according to the collected bandwidth allocated to access equipment by the wireless network. How to analyze and refine the conventional technical means of those skilled in the art is not used to limit the protection scope of the present invention, and is not described herein again.

On the other hand, the service type information transmitted by the equipment through the network, such as VoIP, voice, interactive games, video and video conferences, is acquired and obtained through a deep packet inspection technology; the service type information and the QoS resource information actually allocated to the device (such as QoS indexes such as actual internet access bandwidth of the device) are collected through interaction with a Policy and Charging control unit (PCRF) network element. The detailed implementation is a matter of routine skill for those skilled in the art, and is not intended to limit the scope of the present invention, which is not described herein.

Step 101: and when determining that the reference QoS or the actual scene requirement corresponding to the service cannot be met according to the QoS resource information actually allocated to the equipment, adjusting the QoS index of the equipment according to the QoS resource condition available to the wireless network.

In this step, if it is determined that the reference QoS or actual scene requirement corresponding to the service is satisfied, the process is ended.

In this step, determining that the reference QoS or actual scene requirement corresponding to the service cannot be met according to the QoS resource information actually used by the device specifically includes:

determining whether the QoS index of the wireless network of the device is necessary to be adjusted according to QoS resource information actually used by the device, such as QoS indexes of actual internet access bandwidth of the device, service types transmitted by the device through the wireless network and reference QoS or actual scene requirements of the service types: when the actual internet bandwidth QoS index of the equipment is lower than the reference QoS or actual scene requirement of the service type transmitted by the equipment through the wireless network, the QoS index of the equipment is determined to be required to be adjusted, so that better network communication service is provided for the equipment. It should be noted that, the reference QoS of the service types transmitted by the device through the wireless network defines the basic QoS indicator that satisfies the requirement of using various service types by the device for accessing the internet, which may be referred to as a related protocol specifically, and does not belong to the protection scope of the present invention.

In this step, adjusting the QoS index of the device according to the QoS resource condition available to the wireless network specifically includes:

according to the obtained available QoS resource information of the wireless network, namely the surplus and free available QoS resource conditions of the wireless network, whether the QoS index meeting the requirements of the equipment can be provided or not is determined, if the QoS index meeting the requirements can be met, a QoS index adjusting instruction can be pushed to the equipment, and the QoS index adjusting instruction is recommended to initiate the adjustment of the QoS index, or the QoS index of the equipment is automatically adjusted. The QoS index adjustment instruction may be determined according to actual equipment and application conditions. For example, for a mobile phone user, the instruction is a configurable short message template, and in this case, the short message is sent to the user equipment to inform the user that the current network is unstable and cannot meet the current internet access requirement, and whether the network service quality needs to be improved. The short message template may be different according to the actual operation requirements of different operators, and it may be informed that the user generates more traffic or needs additional charges.

When the QoS index adjustment instruction is selected to be pushed to the equipment, the method of the invention further comprises the following steps:

the equipment organizes and sends a QoS index adjusting instruction to the PCRF after receiving the QoS index adjusting instruction and according to the existing Rx interface protocol so as to provide a QoS index adjusting request;

and the PCRF sends a QoS index adjustment instruction to the PCEF, collects an adjustment result from the PCEF, and finally feeds back the QoS index adjustment result to the equipment to finish the QoS index adjustment of the equipment. Here, when the Rx interface is actually used to send the QoS indicator adjustment instruction, corresponding parameters, such as priority, maximum uplink bandwidth, maximum downlink bandwidth, etc., are provided according to the actual adjustment condition of the target user, which is not limited herein.

When the QoS index of the device is automatically selected to be adjusted, the method of the present invention further includes:

and automatically sending a QoS index adjustment instruction to the PCRF according to an Rx interface protocol, issuing the QoS index adjustment instruction to the PCEF by the PCRF, collecting an adjustment result from the PCEF by the PCRF, feeding the QoS index adjustment result back to the equipment as required, and completing the QoS index adjustment of the equipment.

The invention analyzes the actual requirement of the equipment for the QoS when accessing the wireless network to the Internet by analyzing the QoS index of the wireless network of the operator, particularly the free amount of the network bandwidth, and when the QoS index of the wireless network is found to be surplus and free and the actual enjoyed QoS index of the equipment can not meet the requirement of the service type transmitted by the equipment through the network under the normal condition, an adjustable QoS index instruction is provided for the equipment, and the QoS index of the equipment receiving and responding to the adjustment instruction is adjusted, or the QoS index is automatically adjusted for the equipment. By the method, redundant bandwidth of an operator is effectively and reasonably utilized, and better network communication service is provided for equipment.

Fig. 2 is a schematic structural diagram of a device for implementing QoS management of a wireless network, as shown in fig. 2, the device at least includes a bearer analysis module, a network interaction module, a QoS decision module, and a processing module; wherein the content of the first and second substances,

the bearing analysis module is used for acquiring QoS resource information available for the wireless network; the method is specifically used for acquiring information on a wireless base station and a core network such as SGSN/MME to determine the wireless network bearing capacity, and analyzing and extracting the surplus and idle available QoS resource information of the wireless network through the acquired bandwidth allocated to the access equipment by the wireless network.

The network interaction module is used for acquiring QoS resource information actually used by the equipment; the method is specifically used for acquiring and obtaining the service type of the equipment transmitted through the network by using a deep packet inspection technology; through interaction with a PCRF network element, QoS resource information actually allocated or occupied by the equipment, such as QoS indexes of actual internet access bandwidth of the equipment, is acquired.

And the QoS decision module is used for informing the processing module when the QoS resource information actually distributed or occupied by the equipment is determined to be incapable of meeting the reference QoS or the practical scene requirement corresponding to the service. The information reported by the bearing analysis module and the network interaction module is received, the information is analyzed, and when the QoS index needs to be adjusted for the equipment, the processing module is informed to perform corresponding adjustment operation; the method is specifically used for determining the QoS index of the equipment needing to be adjusted and informing the processing module when the QoS index of the actual internet access bandwidth of the equipment is lower than the reference QoS index or the practical scene requirement of the service type transmitted by the equipment through the wireless network. That is, according to the QoS resource information actually used by the device, such as QoS indexes of the actual internet bandwidth of the device, the service type of the device transmitted through the network, and the reference QoS index or the actual scene requirement of the service type of the device transmitted through the network, it is determined whether there is a need to adjust the QoS index of the wireless network of the device: when the QoS index of the actual internet bandwidth of the equipment is lower than the reference QoS index or the actual scene requirement of the service type transmitted by the equipment through the network, the QoS index of the equipment is judged to be required to be adjusted, meanwhile, the QoS index is further processed by combining the condition of the QoS resources available to the wireless network, and when the QoS resources available to the wireless network redundancy can meet the QoS index required by the equipment, the processing module is informed to adjust the QoS index for the equipment.

Before notifying the processing module, the QoS decision module may further determine whether the authentication device has a condition for adjusting the QoS index according to a need, and send a QoS index adjustment notification to the processing module only if the authentication device has the condition.

And the processing module receives the notice from the QoS decision module and determines whether to recommend the QoS index adjustment for the equipment or automatically adjust the QoS index for the equipment according to the type or the attribute information of the equipment. When a mode of recommending to adjust the QoS index for the equipment is adopted, the processing module pushes a QoS index adjustment suggestion instruction to the equipment, if the equipment receiving the adjustment suggestion instruction replies to the processing module, the equipment replies according to the mode provided in the suggestion instruction, at the moment, the processing module sends a formal adjustment notice to the network interaction module, and the notice message contains the specific QoS index to be adjusted; when the mode of automatically adjusting the QoS index is adopted, the processing module automatically sends a formal adjustment notice to the network interaction module, and the notice message contains the specific QoS index to be adjusted.

The QoS decision module is also used for judging whether the authentication equipment has the condition for adjusting the QoS index, and if so, sending a QoS index adjusting instruction to the network interaction module.

Correspondingly, the network interaction module is further configured to receive a QoS index adjustment instruction from the processing module, interact with a PCRF network element through an Rx protocol interface, and request for QoS index adjustment for the device; receiving the adjustment result of the QoS index from the PCRF and returning the adjustment result to the processing module; at this time, the processing module is further configured to notify the device of the QoS adjustment result according to actual needs.

Fig. 3 is a flowchart illustrating an embodiment of obtaining a wireless network bearer capability according to the present invention, and with reference to fig. 2, the flowchart shown in fig. 3 includes:

step 300: the bearing analysis module initiates a request for collecting the bearing capacity data information of the wireless access network to the wireless base station so as to obtain the information including the reserved or allocated uplink/downlink network bandwidth.

Step 301: the wireless base station returns the acquired result data, namely the bearing capacity data information to the bearing analysis module.

Step 302: the bearer analysis module initiates a request to the SGSN or MME to collect the reserved bandwidth or the allocated bandwidth.

It should be noted that step 300 is to collect from the radio access network, and this step is to collect from the core network, and those skilled in the art will readily know that the processing here is to obtain more accurate information.

Step 303: the SGSN or the MME returns the acquisition result data, namely the reserved bandwidth or the allocated bandwidth of the wireless network to the bearing analysis module.

Step 304: the bearing analysis module analyzes and calculates the surplus and idle available QoS resource information of the wireless network through the information collected from the wireless base station and the core network. How to analyze and calculate the technical means which are conventional for those skilled in the art is not used to limit the scope of the present invention, and is not described herein again.

Fig. 4 is a schematic flow chart of an embodiment of obtaining an actual internet QoS indicator of a device according to the present invention, and with reference to fig. 2, the flowchart shown in fig. 4 includes:

step 400: the network interaction module interacts with a PCRF network element through an Rx protocol interface and subscribes the QoS index of the equipment to the PCRF by using an Authentication Authorization Request (AAR) message.

Step 401: and the PCRF subscribes the QoS index of the equipment to the PCEF by using a re-authentication request (RAR) message through a Gx protocol interface between the PCRF and the PCEF.

Step 402: and the PCEF reports the QoS index to the PCRF by adopting a Re-authentication response (RAA, Re-Auth-Answer) message according to the registered subscription event.

Step 403: the PCRF uses the AAA message to return the QoS index parameters of the subscribed equipment, such as the QoS indexes of the actual internet access bandwidth of the equipment, to the network interaction module.

In addition, the network interaction module informs the PCRF of sending a subscription instruction to the PCEF supporting the deep packet inspection technology through the Rx protocol interface to indicate that the PCEF detects data information flowing through the network, the PCEF detects the service type information transmitted by the device through the network, and then the PCEF feeds back the detected service type confidence to the PCRF, and the PCRF feeds back the information to the network interaction module, such as the service types of VoIP, voice, interactive games, video and video conferences, and the like, and the network interaction module sends the service type information transmitted by the device through the network to the QoS decision module.

Fig. 5 is a schematic flow chart of an embodiment of a decision for adjusting the QoS indicator of the device for internet access and issuing the decision according to the present invention, and with reference to fig. 2, fig. 5 includes:

Step 501: and the network interaction module reports the wireless QoS index actually used by the equipment, namely the QoS resource information actually used by the equipment to the QoS decision module.

Step 502: and the network interaction module reports the service type transmitted by the equipment through the network to the QoS decision module.

Step 503: the QoS decision module comprehensively analyzes and judges whether the QoS index adjustment needs to be carried out on the equipment: if the device actually accesses the internet, the network QoS index actually used when accessing a certain type of service or the type of the transmitted service cannot meet the required standard QoS index or the actual scene requirement, meanwhile, the QoS decision module judges that the wireless bearing capacity of the current wireless network can meet the QoS index required by the device, and in addition, when the authentication device has the condition of adjusting the QoS index, the QoS index of the wireless network of the device needs to be adjusted.

The authentication in this step may support authentication of the device with respect to conditions such as a device attribute identifier (used to identify the identity of the device), a device state (such as normal, abnormal, or inactive), and the like. These conditions can be configured and adjusted according to the actual deployment requirement, and are not limited.

Step 504: and the QoS decision module issues a QoS index adjustment instruction for the equipment to the processing module.

Fig. 6 is a schematic flow chart of an embodiment of adjusting the QoS indicator of the device for internet access according to the present invention, and with reference to fig. 2, the flowchart shown in fig. 6 includes:

Step 601: if the device feedback requires to improve the QoS, the QoS index adjustment application can be submitted to the processing module through a short message or an API interface mode.

Step 602: and the processing module sends a QoS index adjustment instruction to the network interaction module.

Step 603: the network interaction module interacts with a PCRF network element through an Rx protocol interface, for example, sends an AAR request message to the PCRF to request QoS index adjustment for the device.

The AAR is a protocol interface message, which includes many parameters according to the protocol specification, where the parameters include some operation types, the step corresponds to the QoS application operation type, the step 400 corresponds to the actual QoS condition of the user, and the two types of flows also have different other parameters.

Step 604: the PCRF and the PCEF interact through a Gx protocol interface, and the PCRF can inform the PCEF of carrying out QoS index adjustment on the equipment by adopting an RAR message.

Step 605: after the PCEF completes the adjustment, the QoS index adjustment result can be reported to the PCRF through the RAA message.

Step 606: after receiving the QoS index adjustment result of the PCEF, the PCRF may use an AAA message to feed back the adjustment result of the QoS index for the device to the network interaction module.

Step 607: the network interaction module returns the QoS index adjustment result to the processing module.

Step 611: and the processing module informs the equipment of carrying out QoS adjustment according to the QoS index adjustment result.

In the case of automatically adjusting the QoS index for the device, the interaction with the device is not involved, and only step 602 to step 608 need to be executed.

In summary, the method and the apparatus for implementing QoS management of a wireless network according to the present invention evaluate whether QoS adjustment is required by comprehensively analyzing the carrying capacity, the bandwidth usage, the actual QoS index of the device during internet access, and the internet access experience of the device. Furthermore, according to the business mode needs of operators or according to the equipment type characteristics, a mode of adjusting QoS by recommending equipment and then actively initiating QoS index adjustment by the equipment can be adopted; or, the device for realizing QoS management of the invention directly adjusts the QoS index for the equipment needing QoS adjustment.
