Abstract
The invention provides a method for performing strategy identification and control by using user service identification (USID) in an evolved packet system. In the method, a loading identifier is replaced by a flow label in an IPv6 data packet head, namely the flow label is used as the USID for identifying the quality of service (QoS) grade set quintuple and a charging rule of each data stream in the EPS; a corresponding USID for identifying the security grade of the data stream QoS is generated by searching a self-reconfigured policy and charging control (PCC) rule and a USID mapping table after a policy and charging rule function (PCRF) of each network element judges that a request object obtains a PCC rule including a certain QoS grade set and charging; because each network element in the system abides by an internet protocol (IP) and can identify the USID, and uplink and downlink network elements of each data stream are preconfigured with the PCC rule and the USID mapping table, QoS consultation and authentication can be executed simply and intelligently, the QoS is provided conveniently and flexibly, and a transmission strategy and a charging control can be executed at the same time. The method for performing strategy identification and control by using the USID enhances the function of network memorizing QoS information, enables the network to be more intelligent and has relatively great advantages in the aspects of improving the network efficiency, reducing the network load and the like.
Description
Technical field
The present invention relates to a kind of at evolved packet system EPS(Evolved Packet System) in utilize user's service identifiers USID(User Service Identification) method of implementation strategy sign and control, belong to the mobile communication technology field.
Background technology
The EPS network is the model of following mobile network's development of 3GPP standard, is made up of Access Network and core net EPC.Wherein, Access Network comprises user terminal UE and evolution grouping base station eNodeB, and EPC comprises the mobile management entity MME of negotiation phase, the gateway SGW of transfer phase and the gateway PDN-GW of Packet Data Network.Except MME, other each network elements all are closely related with the enforcement of QoS mechanism.
In EPS, multiple important application all needs QoS to provide support, as voice frequency telephone, video conference, HDTV (High-Definition Television) etc.These are used and drive the exploration that many research institutions are devoted to relevant problem.Wherein, strategy and charging control PCC (Policy and Charging Control) are the focuses of research with the binding mechanism of bearing identification all the time, and scientific and technical personnel in the industry pay much attention to, pay close attention to and put into the research and development of QoS control and binding mechanism.
At present, in the negotiation and renewal process of the QoS of EPS and billing model, each network element (comprising user terminal UE, evolution grouping base station eNodeB, gateway SGW and packet data network gateway PDN-GW) all will participate in this process, and, when the user wished to obtain again QoS request that network authorized, each network element among the EPS must repeat the overall process of original negotiation and mandate.Its idiographic flow is as follows:
At first, network will carry out the pre-configured of necessity before accepting negotiation information, and each network element needs to dispose a USID mapping table, is used for setting up the corresponding relation of EPS qos parameter and bearing identification.This USID mapping table comprises bearing identification, QoS class set five-tuple and charging regulation.But, be empty in the information of pre-configured stage bearing identification item, need after consulting, to insert; QoS class set five-tuple comprises QoS classification logotype QCI, distribution and maintenance priority ARP, guarantees bit rate GBR, maximum bit rate MBR and Aggregate Maximum Bit Rate AMBR.Secondly, when a QoS request arrived network, the PCC that is positioned at core net at first judged QoS grade and charging case that this request allows to obtain, if can satisfy, it is regular and issue just to generate PCC who has a series of EPS qos parameters.The PCC rule is made up of QoS class set five-tuple and charging regulation.After PDN-GW on the way, SGW, eNodeB receive the PCC rule that core net issues, for request object is set up bearer path, and in the USID allocation list, insert bearing identification, this bearing identification and corresponding QoS attribute are bound together (replacing with TFT during the no identification number of carrying).
Again, behind conversation end, setting up all good bearer paths relevant with this session all can be deleted along with the cancellation in path, and namely all bearing identifications relevant with this session also can be deleted from the USID mapping table.After, when same user is intended for the identical QoS of another data flow application service, must restart identical negotiation and licensing process; Because in the network with last time employed bearing identification deleted.In this case, EPS will regard it as a strange request, and all module will be again to its mandate among the PCC, and all network elements also will repeat inquiry and the binding procedure in the whole negotiation.
The implementation process of current EPS QoS need to consume the storage of each network element and the resource of calculating, and, the increase of the number of the data flow that this process also will be supported along with network element the expense of resource and increasing.Its reason is as follows: for QoS negotiation each time, network element all will be set up the mapping relations that a USID mapping table is set up bearing identification number (or TFT) and concrete QoS attribute, and in the implementation process that QoS guarantees, each network element except UE is after receiving from the upstream or downstream packet, all will find the list item of its ownership and this packet is implemented follow-up QoS to guarantee according to the USID mapping table of number (or TFT) inquiry of the bearing identification in the packet oneself; And the information in the USID mapping table is deleted behind conversation end.
This shows that the USID mapping table in the network element is dynamic change along with the foundation of bearer path and deletion, the foundation in path each time or deletion all will trigger interpolation or the deletion action of a certain list item.When same user was intended for the same QoS of another data flow application service next time, network can not remembered any relevant QoS information with it.EPS still regards it as a strange request, and all modules will be again to its mandate among the PCC, and all network elements also will repeat inquiry in the overall negotiation process and whole operations of binding.Therefore, the implementation process of current EPS QoS, consumed the resource of storage and the calculating of each network element, and, this process to the expense of resource, be the number unanimity that bar number in the list item can need the data flow supported along with network element is current, that is to say, the data flow of applying for this network element support QoS assurance is more many, the clauses and subclauses of the USID mapping table of this network element are just more many, and are also just more big to the consumption of network element resources, thereby restricted the extensibility of equipment in the network.
From the above mentioned, there is certain limitation in the QoS of current EPS with the negotiation of billing model and licensing process, and its attribute with bearing identification and QoS is bound mutually, will cause following two problems:
Complicated and forgetful QoS consults and licensing process: all network elements of the prior art all must participate in consulting and licensing process, and upgrade its USID mapping table according to the situation of consulting.In case conversation end, bearer path information all in the network make when the user initiates same request again all with deleted, need restart the process of consulting and authorizing, and all network elements also must participate in the overall process of duplicate negotiation loops mandate in the network, have increased the weight of the burden of PCC.
The QoS that expense is big implements: because all network elements all will participate in consulting and authorizing, the list item of USID mapping table must be safeguarded and store to each network element, simultaneously the number of list item will increase along with the increase of the number of the data flow of its support, will consume a lot of calculating and stored resource.
The root of the problems referred to above is that existing QoS information can only depend on the foundation of carrying, and is bound to the identification number of carrying.And for each disposable QoS carrying, prior art from setting up, being maintained into the overall process of deletion, is all wanted consumption of natural resource (as time, memory space or computational resource) between user terminal and each network element.If can in data transmission procedure, QoS information be separated from the identification number of carrying, the problems referred to above are readily solved.Therefore, for working out a kind of solution efficiently, just become at present the emphasis problem of scientific and technical personnel's concern in the industry.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of user's service identifiers USID implementation strategy sign and method of controlling in evolution packet network EPS, utilized, come the alternative bearer sign in order to adopt the flow label field in the basic header of IPv6 of the present invention, with the mapping of realization and qos parameter, thereby QoS information and bearing identification are separated.The present invention can realize following target:
Simple and intelligent QoS consults and licensing process: the intermediate NE of the inventive method will adopt static USID mapping table, make it need not participate in consulting and licensing process, to alleviate the workload of PCC.
Economic and QoS implementation step flexibly: owing to realize and the binding of QoS information that with stream label network element does not need to participate in QoS negotiation and licensing process, does not namely need Dynamic Maintenance USID mapping table, thereby saves computational resource greatly; Simultaneously, stream label can be supported the polymerization of data flow, and the data flow that namely has identical QoS attribute can identify by enough same stream labels, reduces the list item of USID mapping table, can better adapt to the expansion of network size.
In order to reach the foregoing invention purpose, the invention provides a kind of user's service identifiers USID implementation strategy sign and method of controlling in evolved packet system EPS, utilized, it is characterized in that: the flow label field in the IPv6 data packet head is replaced bearing identification, be about to stream label as user's service identifiers USID(User Service Identity), for QoS class set five-tuple and the charging regulation thereof of each data flow of sign EPS; This USID is that regular entity PCRF by the strategy of each network element and the control of chargeing is after request object of judgement obtains to comprise the PCC rule of certain QoS class set and charging, generate corresponding USID by inquiring about the regular mapping table with USID of himself pre-configured PCC, be used for the guarantee grade of this data flow of sign QoS; Because all network elements in the EPS system are all followed and are carried out the IP agreement and can identify USID, the network element of the uplink and downlink of each data flow presets the mapping table of PCC rule and USID, thereby can carry out negotiation and the mandate of QoS and implement the QoS service, carry out transmission policy simultaneously and the control of chargeing; Described method comprises following operating procedure:
(1) generate the USID mapping table: this USID mapping table is made up of stream label, QoS class set and charging regulation, wherein each element of QoS class set depends on a five-tuple: priority ARP, the bit rate GBR that guarantees, maximum bit rate MBR and Aggregate Maximum Bit Rate AMBR are reserved in QoS class letter QCI, carrying, and wherein QCI is provided with 9 kinds; Charging regulation is to be defined voluntarily according to demand separately by operator or the user that uses USID; The value of stream label adopts hash function to generate according to QoS class set five-tuple and charging regulation;
(2) pre-configured USID mapping table: this USID mapping table is preconfigured into respectively among base station eNodeB, gateway SGW and the packet data network gateway PDN-GW, and stream label numerical value has been inserted and constant all the time in this pre-configured USID table;
(3) negotiation of USID and licensing process: the corresponding operating of finishing this step according to initial negotiation and mandate or the dual mode of exempting to consult;
(4) implementation process of USID: each network element is learned the corresponding QoS class set of stream label, and corresponding QoS service implementation is provided according to inquiry USID mapping table.
Described USID comprises preceding 15 bits of the stream label in the IPv6 datagram header at least, back 5 bits give over to subsequent expansion, what each QoS class set five-tuple of sign and charging regulation thereof can be provided is combined as 32767 kinds, and the various QoS that can satisfy operator can provide at present serve and charge required.
The process that described step (1) generates the USID mapping table is: define a QoS class set earlier, each element in this set depends on following five-tuple: QoS class letter QCI, carrying are reserved priority ARP, are guaranteed bit rate GBR, maximum bit rate MBR and Aggregate Maximum Bit Rate AMBR; And define one and according to demand separately the wherein PCC charging regulation of element is set by operator or user; The five-tuple that random extraction is set from the QoS class set is as an element again, and with this element and PCC charging regulation respectively as two inputs of hash function, generate stream label by hash function, this stream label is formed the USID mapping table with corresponding QoS class set and charging regulation again; This hash function can select for use any one cryptographic algorithm to realize, and guarantees that the PCC rule realizes mapping relations one to one with the USID mapping table.
Described USID mapping table is static, each the PCC rule that is made of QoS class set five-tuple and charging regulation thereof in can precise marking EPS; And the mapping relations in this USID mapping table also are static, do not change along with the variation of data flow.
Initial negotiation in the described step (3) and authorization are applicable to the data flow TFT(Traffic Flow Template that never consulted QoS request), receive the QoS request after, carry out initial negotiation with PDN-GW; Described data flow TFT is used for each data flow of unique identification; This process comprises following concrete operations content: after the regular entity PCRF of strategy and the control of chargeing receives request from application entity AF, judge the qos parameter of this request earlier, to obtain the PCC rule, generate QoS by the inquiry USID mapping table generation flow label values corresponding with it then and reply, this replys the mapping relations of the data flow TFT that comprises stream label and request; After PCEF receives that QoS replys, just upgrade the binding table of its stream label and TFT; After SGW and eNodeB receive that QoS replys, do not carry out any processing, directly be transmitted to UE; UE receives this QoS and replys, and is stored as the binding table of a TFT and stream label.
The content of operation of exempting from negotiation mode in the described step (3): during each conversation end, UE or AF store the mapping of certain data flow TFT and a concrete data flow label value; If be the identical data flow of TFT numerical value next time, the UE just PCRF in the PCC adjudicates again and authorizes, and directly uses the stream label FL of this preservation just to obtain corresponding QoS service; But for insincere user or only allow the business of chargeing by the duration mode, based on security consideration, PCC only allows AF behind PCEF registration flow label value, is distributed to UE again.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with drawings and Examples.
As the system of all-IPization, EPS all adopts the IP agreement in all network elements.Compare with traditional IPv4, IPv6 has a lot of advantages, comprises abundant address resource, the QoS feature of the locomotive function of enhancing and expansion etc.All network element, it is very simple that USID is set in IPv6 in EPS; And will solve layer (crosslayer) problem of striding in the existing EPS system.QoS and charge information are collected at the IP layer, rather than at GPRS Tunnel Protocol layer, radio bearer key-course and mobile IP layer.
The present invention utilizes USID implementation strategy sign and the method for controlling in EPS, be that the flow label field in the IPv6 data packet head is replaced bearing identification, be about to stream label as user's service identifiers USID, be used for QoS class set five-tuple and the charging regulation thereof of each data flow of sign EPS; This USID is that regular entity PCRF by the strategy of each network element and the control of chargeing is after request object of judgement obtains to comprise the PCC rule of certain QoS class set and charging, generate corresponding USID by inquiring about the regular mapping table with USID of himself pre-configured PCC, be used for the guarantee grade at this data flow of EPS sign QoS; Because all network elements in the EPS system are all followed and are carried out the IP agreement, the network element of the uplink and downlink of each data flow presets the mapping table of PCC rule and USID, each network element also can both be identified USID, thereby can carry out negotiation and the mandate of QoS simply, intelligently, convenient, implement the QoS service neatly, carry out transmission policy simultaneously and the control of chargeing.
In the inventive method, preceding 15 bits of stream label are used for sign USID, have 32767 kinds of combinations and can be used for unique QoS of sign and charging regulation, other application that back 5 bits are left subsequent expansion for.And supposition has only two kinds of COS: voice service charged according to time and the e-mail that charges by flow service.
Referring to Fig. 1, introduce the concrete operations step of the inventive method embodiment:
Referring to Fig. 2, after introducing the generative process of mapping table: PCRF and receiving request from AF, judge the qos parameter of this request earlier, to obtain the PCC rule, generate QoS by the inquiry USID mapping table generation flow label values corresponding with it then and reply, this replys the mapping relations of the data flow TFT that comprises stream label and request; After PCEF receives that QoS replys, just upgrade the binding table of its stream label and TFT; After SGW and eNodeB receive that QoS replys, do not carry out any processing, directly be transmitted to UE; UE receives this QoS and replys, and is stored as the binding table of a TFT and stream label.
Suppose that FL=0X1002* represents voice service; FL=0X1006* represents the e-mail service.The corresponding relation of its PCC rule and stream label is referring to shown in Figure 4.
This step comprises following content of operation:
(21) be applicable to initial negotiation and the licensing mode of the data flow TFT that never consulted QoS request: after receiving the initial QoS request of user, carry out initial negotiation with PDN-GW; Data flow TFT is used for each data flow of unique identification.
Suppose that User IP v6 address is 2001:db8::6, two QoS request forms that then send are respectively:
The filtration parameter of request 1: { 2001:db8::6,2001:db8::27,653,205,6}, qos parameter: { time delay=150ms, packet loss=10
-3, bandwidth=any, COS=video-conference};
The filtration parameter of request 2: { 2001:db8::6,2001:db8::82,25,465,17}, qos parameter: { time delay=300ms, packet loss=10
-6, bandwidth=any, COS=e-mail}.
PCRF judges whether to support corresponding QoS according to user's request, if can, it is right then to generate corresponding { filtration parameter, stream label }, and two records that generate are added to during QoS replys.This QoS replys and is passed to PCEF, SGW, eNodeB and UE respectively.After PCEF receives that QoS replys, will upgrade the binding table of its stream label and TTF, and after SGW and eNodeB receive that QoS replys, and just transmit and be left intact.QoS replys the binding table of participation PDN-GW respectively referring to Fig. 5 and shown in Figure 6.UE receives after QoS replys, and then it can be added in the binding table (referring to shown in Figure 7).
(22) exempt from negotiation mode: behind each conversation end, UE or AF will record the mapping relations between certain data flow qos parameter and the stream label, the i.e. mapping of this data flow TFT and its label value; If be the identical data flow of TFT numerical value next time, the UE just PCRF in the PCC adjudicates again and authorizes, and directly uses the stream label FL of this preservation just to obtain corresponding QoS service; But for insincere user or only allow the business of chargeing by the duration mode, based on security consideration, PCC only allows AF behind PCEF registration flow label value, is distributed to UE again.For example, the mapping relations between qos parameter and the stream label are:
The qos parameter of record 1: { time delay=150ms, packet loss=10
-3, bandwidth=any, COS=video-conference}, FL=0X1002*;
The qos parameter of record 2: { time delay=300ms, packet loss=10
-6, bandwidth=any, COS=e-mail}, FL=0X1006*.
After, when the user needs same QoS request when (as recording the e-mail service in 2) next time, same QoS request described here refers to adopt the data flow of same TFT sign, and then the user can directly reuse FL=0X1006* and obtains service and do not need to consult again.
In up link, for request 1, UE checks the TFT(five-tuple in the grouping): 2001:db8::6,2001:db8::27,653,205,6}, and the corresponding FL=0X1002* of mark sends to eNodeB then in grouping; ENodeB and SGW read the FL=0X1002* of grouping, provide specific QoS service by the USID mapping table of searching them; After PDN-GW receives grouping from SGW, check the TFT(five-tuple): { whether 2001:db8::6,2001:db8::27,653,205,6} are authorized to and use corresponding FL=0X1002* in the grouping, and it is chargeed.
In down link, for request 1, PDN-GW also is by the TFT(five-tuple): { 653,205,6} comes the corresponding FL=0X1002* of mark packets, and before transmitting them it is chargeed for 2001:db8::6,2001:db8::27; ENodeB and SGW also are to use the USID mapping table that corresponding specific QoS service is provided.
The embodiments of the invention test is successful, has realized goal of the invention.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
