Embodiment
Fig. 1 is the flow chart of business access method embodiment one of the present invention, and as shown in Figure 1, the method for the present embodiment can comprise:
Step 100 is resolved the request message for the first business that subscriber equipment (User Equipment is hereinafter to be referred as UE) sends, and obtains the type of service of the first business.
Concrete, AC carries out deep-packet detection to the request message of the first business that UE sends, and analyzes Internet protocol (Internet Protocol is hereinafter to be referred as IP) payload package content, obtains the type of service of the first business.First kind type of service comprises: point-to-point service or long-term online class business, for example BT downloading service, QQ business.
Step 101, if the type of service of the first business belongs to default first kind type of service, relatively current network takies resource and the first congestion threshold of presetting.
Concrete, judged that by AC the type of the first business belongs to first kind type of service or belongs to other types of service.If the type of service of the first business belongs to default first kind type of service, AC compares the first congestion threshold that current network takies resource and presets.AC relatively current network a kind of embodiment of taking resource and default the first congestion threshold can be: set in advance a percentage, as the first congestion threshold, calculate the percentage that current network takies resource and network total resources, the percentage and the first congestion threshold that obtain with this calculating compare.This first congestion threshold can be an empirical value, can determine according to the situation of concrete network, herein not with restriction.
Step 105 is less than or equal to the first congestion threshold if current network takies resource, the priority of first business that raises in default type of service priority list, and type of service priority list access the first business after raising according to the first service priority.
Concrete, set in advance a type of service priority list in AC.In this type of service priority list, because point-to-point service or long-term online service needed take Internet resources in a large number, affect other business, so point-to-point service or be set to than low level in the priority of line service in this type of service priority list for a long time, even can be set to minimum rank, for example, the priority of the business such as BT downloading service and QQ business is set to minimum rank.In this step, if taking resource, current network is less than or equal to the first congestion threshold, illustrate that this moment, Internet resources had larger slack resources, can be by revising this type of service priority list, improve the priority of the first business, namely improve point-to-point service or for a long time in the priority of line service, improve the service quality of the first business.
in the embodiment of the present invention one, the request message for the first business that AC sends by resolving UE, obtain the type of service of the first business, if the type of service of the first business belongs to default first kind type of service, relatively current network takies resource and the first congestion threshold of presetting, if taking resource, current network is less than or equal to the first congestion threshold, the priority of first business that raises in default type of service priority list, and type of service priority list access the first business after raising according to the first service priority, realize adopting variable priority to access, for example, current network takies resource network and the first congestion threshold compares, when current network takies resource network less than the first congestion threshold, AC passes through said method, Streaming Media (the Bit Torrent that script priority is lower, be called for short: BT) priority of downloading service raises, thereby rationally utilize fully Internet resources.
Based on the business access method that Fig. 1 provides, further, Fig. 2 is the flow chart of business access method embodiment two of the present invention, and as shown in Figure 2, the method comprises following process.
Step 100 is resolved the request message for the first business that UE sends, and obtains the type of service of the first business.
Step 101: whether the type of service that judges the first business belongs to default first kind type of service.
If so, execution in step 102.Otherwise execution in step 110.
Step 102, relatively current network takies resource and the first congestion threshold of presetting.
If taking resource, current network is less than or equal to the first congestion threshold, execution in step 103; If current network takies resource greater than the first congestion threshold, execution in step 110.
Step 103 sends rising priority query message to UE.
Step 104 receives UE and replys message and judge that this reply message is for being or no.
Concrete, if the reply message of UE is yes, execution in step 105, if the reply message of UE is no, execution in step 110.
Step 105, the priority of first business that raises in default type of service priority list, and type of service priority list access the first business after raising according to the first service priority.
Concrete, first kind type of service comprises: point-to-point service or long-term online class business.And, after the priority with the first business raises, be the first business interpolation priority rising sign, this sign is used for representing that the current priority of the first business is the priority through raising.Perhaps, in another kind of implementation, the memory priority level is adjusted record in AC, and is historical with the adjustment of recording each service priority.
As shown in Figure 2, after step 105, can also comprise the following steps 106 to step 109.
Step 106 generates the Charging Data Record of the first business and sends to accessing control server according to the type of service priority list, so that accessing control server is carried out charging according to the Charging Data Record of the first business to the first business.
Step 107 is obtained the request message for the second business, and relatively current network takies resource and the second congestion threshold of presetting.
Concrete, the second congestion threshold is also a default percent value, its concrete size will not limit, but will guarantee that the second congestion threshold is larger than the first congestion threshold, and a larger scope is arranged between the first congestion threshold and the second congestion threshold.For example the first congestion threshold is made as 30%, and the second congestion threshold can be set to 70%.when accessing the first business after the priority with the first business raises, if the percentage of the resource that current network takies and network total resources is no more than the second congestion threshold, priority list access first business of AC after according to the priority of first business that raises, if the percentage of the resource that current network takies and network total resources surpasses the second congestion threshold, access according to the priority list after the priority of first business of rising the resource congestion that the first business can cause current network to take, so, when the resource that takies in current network and the percentage of network total resources surpass the second congestion threshold, AC reduces the priority of the first business in the type of service priority list.Further, in this step, in the situation that adjusted before the first service priority, if get the request message for the second business, current network is taken resource and compare with the second congestion threshold of presetting.In one implementation, AC can raise according to the priority that the first business is carried and identify, and knows that the current priority of the first business is the priority through raising.Perhaps, in another kind of implementation, the AC Query priority is adjusted record, knows that according to this record the current priority of the first business is the priority through raising.
Step 108 if current network takies resource more than or equal to the second congestion threshold, reduces the priority of the first business in the type of service priority list, and type of service priority list access the second business after reducing according to the first service priority.
Step 109, generate the Charging Data Record of the first business and the second business and send to accessing control server according to the type of service priority list, so that accessing control server is carried out charging according to the Charging Data Record of the first business to the first business, according to the Charging Data Record of the second business, the second business is carried out charging.
Step 110 is according to default type of service priority list access the first business.
Concrete, in step 101, if the type of service of the first business does not belong to default first kind type of service, carry out this step 110.In step 102, if current network takies resource greater than the first congestion threshold, carry out this step 110.In step 104, if the reply message of UE is no, carry out this step 110.
Step 111 generates the Charging Data Record of the first business and sends to accessing control server according to default type of service priority list, so that accessing control server is carried out charging according to the Charging Data Record of the first business to the first business.
the business access method that the present embodiment provides, on the basis of business access method embodiment one, further, send rising priority query message and receive UE to UE by AC and reply message, if the reply message of UE is yes, if current network takies resource and is less than or equal to the first congestion threshold, the priority of AC rising first business in default type of service priority list, and type of service priority list access the first business after raising according to the first service priority, make like this UE adjust priority orders between different business according to self-demand and Internet resources situation, provide a kind of priority adjustable service access mode.and, AC sends the priority of the first business to accessing control server, carry out charging by accessing control server according to this priority, wherein, the first service priority if raise, AC sends the priority of the first business after raising to accessing control server, so that accessing control server is carried out charging according to the priority of the first business after raising to the first business, if the first service priority does not raise, AC sends the priority of the first business in default type of service priority list to accessing control server, so that accessing control server is carried out charging according to the priority of the first business in default type of service priority list to the first business.If the reply message of UE is no, AC is according to default type of service priority list access the first business.AC obtains the request message for the second business subsequently, relatively current network takies resource and the second congestion threshold of presetting, if current network takies resource more than or equal to the second congestion threshold, AC reduces the priority of the first business in the type of service priority list, and type of service priority list access the second business after reducing according to the first service priority, send to reduce the priority of the second business after the first service priority to accessing control server, so that accessing control server is carried out charging according to this priority to the second business.Realize adopting variable priority to access, when Internet resources change, adjust the service priority that belongs to first kind type of service, rationally and fully utilize Internet resources, guarantee access and the transmission of different kinds of business.
Fig. 3 is the signaling process schematic diagram of business access method embodiment three of the present invention, below in conjunction with business access method embodiment one of the present invention, two, with reference to Fig. 3, business access method of the present invention is further illustrated, and signaling process comprises:
Step 200, UE sends the request message of the first business to AC.
Concrete, UE initiates a business by access network, and UE need to send to AC the request message of the first business.
Step 202, AC resolves this request message, obtains the type of service of the first business.
concrete, by carrying out deep-packet detection to what UE sent for the first business request information in AC, analyze Internet protocol IP payload package content, obtain the type of service of the first business, further, when the IP packet, transmission control protocol (Transmission Control Protocol, hereinafter to be referred as TCP) or User Datagram Protoco (UDP) (User Datagram Protocol, hereinafter to be referred as, UDP) data flow is passed through based on deep packet inspection technical (Deep Packet Inspection, hereinafter to be referred as DPI) AC the time, AC comes open system interconnection (Open Svstem Interconnect by the content that deeply reads the IP payload package, hereinafter to be referred as OSI) application layer message in seven layer protocols recombinates, thereby obtain the content of whole application program, specifically can be by the recognition technology based on " tagged word ", ALG recognition technology and behavior pattern recognition technology realize.
Step 204, the type of service of AC judgement the first business.
Concrete, if the type of service of the first business belongs to default first kind type of service, AC relatively current network takies resource and the first congestion threshold of presetting.First kind type of service comprises: point-to-point service or long-term online class business, and such as the long-term online business such as BT downloading business, QQ.If current network takies resource when being less than or equal to the first default congestion threshold, continue execution in step 206; When if current network takies resource greater than default the first congestion threshold, direct execution in step 210.
If the type of service of the first business does not belong to default first kind type of service, direct execution in step 210.
Step 206, AC sends rising priority query message to UE.
Concrete, when current network took resource and is less than or equal to the first default congestion threshold, AC sent rising priority query message to UE, with the inquiry UE prioritization of the first business in the type of service priority list that whether raise.
Step 208, UE transmits a reply message to AC.
Concrete, UE can be by the user's prioritization of the first business in the type of service priority list of selecting voluntarily whether to raise after receiving rising priority query message.And with selection result (be or no) by replying message feedback to AC.
Further, receiving this reply message by AC, is yes if the user replys message, the priority of first business that raise in the type of service priority list by AC, then execution in step 210, in step 210, and priority list access first business of AC after according to the priority of first business that raises.If it is no that the user replys message, do not need the raise priority of the first business of AC in the type of service priority list, direct execution in step 210, in step 210, AC is according to default type of service priority list access the first business.
Step 210, AC is according to priority, the type information of the first business, and access the first business also generates Charging Data Record to the expenses standard of the first business.
Concrete, AC raises in the type of service priority list after the priority of the first business, type of service priority list assignment after being raise according to the first service priority by AC configures accordingly, comprise outlet bandwidth assurance etc., AC namely accesses the first business according to priority, the type information of the first business, is about to the first service access in outer net.If in step 208, it is no that the user replys message, when perhaps current network takies resource greater than default the first congestion threshold, this AC according to the priority of the first business in default type of service priority list, type information with the first service access in outer net.And after the first service access outer net, AC generates Charging Data Record according to the type of service priority list.Need to prove, be no if the user replys message, and AC generates the Charging Data Record of the first business according to default type of service priority list.
Step 212, AC sends Charging Data Record to accessing control server.
Step 214, accessing control server is carried out charging according to Charging Data Record.
Concrete, after accessing control server receives Charging Data Record, according to the Charging Data Record of the first business, the first business is carried out charging.
Step 216, accessing control server sends the first service access response message to AC.
Concrete, accessing control server sends the first service access response message to AC.This first service access response message comprises the required bandwidth parameter of the first business, so that AC is according to the first service access response message, priority and type information, the first service access is arrived outer net, and according to bandwidth parameter, the first business is carried out Control for Speed Limitation.
Step 218, UE sends the request message of the second business to AC.
Concrete, after the first service access network of UE, UE initiates second business by access network, i.e. the second business, and UE need to send to AC the request message of the second business.
Step 220, AC resolves this request message, obtains the type of service of the second business, and relatively current network takies resource and the second congestion threshold of presetting.
Concrete, after AC receives the request message of the second business, resolve this request message, obtain the type of service of the second business, compare current network by AC and take resource and the second congestion threshold of presetting.When if current network takies resource more than or equal to the second congestion threshold, reduced the priority of the first business by AC in the type of service priority list.When if current network takies resource less than the second congestion threshold, the access operation of the second business after continuing to carry out according to the type of service priority list after the priority of first business of rising.
Step 222, AC is according to priority, the type information of the second business, and access the second business also generates Charging Data Record to the expenses standard of the second business.
Concrete, AC reduces the priority of the first business in the type of service priority list after, priority assignment second business of the second business in the type of service priority list after being reduced according to the first service priority by AC configures accordingly, comprise outlet bandwidth assurance etc., AC is according to priority, type information access second business of the second business, be about to the second service access in outer net, be lowered due to the priority of the first business this moment, thus AC need according to the first business that is lowered priority, type information again with the first service access in outer net.And after the first business and the second service access outer net, AC generates the Charging Data Record of the first business and the second business according to the type of service priority list.When if current network takies resource less than the second congestion threshold, AC continues according to the priority of the second business in the type of service priority list after the priority of first business of rising, the second service access to be arrived outer net, need not again to access the first business.After the second service access outer net, AC generates the Charging Data Record of the second business according to the type of service priority list.
Step 224, AC sends Charging Data Record to accessing control server.
Step 226, accessing control server is carried out charging according to Charging Data Record.
Concrete, after accessing control server receives Charging Data Record, for the Charging Data Record that comprises the first business and the second business, accessing control server is carried out charging according to the Charging Data Record of the first business and the second business to the second business, and the first business that reduces priority is re-started charging.For the Charging Data Record that only comprises the second business, a Charging Data Record according to the second business carries out charging, will not change the billing operation of the first business before.
Step 228, accessing control server sends the second service access response message to AC.
Concrete, after accessing control server receives Charging Data Record, for carrying out charging and need again situation to the first business charging again the second business, accessing control server produces second a service access response message, this the second service access response message comprises the required bandwidth parameter of the second business and the required bandwidth parameter of the first business, so that AC carries out Control for Speed Limitation according to bandwidth parameter to the second business and the first business.For only carrying out charging to the second business, and the first business is not needed again to upgrade the situation of billing operation, this the second service access response message only comprises the required bandwidth parameter of the second business, so that AC carries out Control for Speed Limitation according to bandwidth parameter to the second business.
