High-speed cache in mobile network has been introduced into the network to have the increasing flow of quantity, for example the Internet traffic in current-dividing network, is repetition because high-speed cache is significant proportion based on the Internet traffic.Therefore, cardinal principle is for example in the different piece of RAN or node or in CN etc., and the copy of (data) content is moved to such an extent that more approach mobile subscriber.The benefit that high-speed cache in mobile network is realized comprises:
A) reduce the cost that transmits content in mobile network.This is that " more than high-speed cache " realized, if because in the transmission link in principle more than high-speed cache, for example in mobile network from media server to CN node or be cached at RAN, in the transmission link between RAN and CN, transmit the content information of a high-speed cache.
B) improve the Quality of experience of mobile phone users.This mainly utilizes lower delay to realize, if because with will fetch information comparison from home position all the time, can return to quickly to mobile subscriber the information of high-speed cache from high-speed cache.
C) for operator provides new service, such as content hosting and stored/backed-up.Mobile operator can with content supplier's conclude an agreement, these agreement based on mobile operator guarantee send the content from particular content provider with efficient way to mobile subscriber or subscriber in the network of mobile operator.
High-speed cache also can be for going to mobile subscriber's distribution of media, replaces that fetch from media server or other users can downloads of media, can fetch media from high-speed cache.How Fig. 1 illustrates to the high-speed cache 6 that is arranged in cordless communication network 1 and pushes from being arranged in internet or being positioned at the media information of one or more media server 5 at service provider place.Conventionally, cordless communication network 1 is also expressed as mobile network, and it comprises RAN3 and CN4.Internet is regarded as the outside at cordless communication network 1.Conventionally from internet or any similar IP network fetch or receiving media information.The UE2 of access RAN3 is directly from high-speed cache 6 rather than from media server receiving media information.Be worth should be mentioned that high-speed cache can be for almost any internet content and Fig. 1 are only the example based on media services.
As described in more early, the cardinal principle of high-speed cache is that the copy of (data) content is moved to such an extent that more approach mobile subscriber.Therefore RAN is the suitable place of implementing one or more high-speed cache in network.But the complexity of the network architecture, comprise distinct interface and function, such as legal or intercept and capture in accordance with the law, charge, mobility and policy control, propose ask for something to the operator of network.In other words, operator should only not place simply high-speed cache and allow mobile subscriber utilize it in RAN.
Legal or intercept and capture (LI) in accordance with the law and relate to according to constituted authorities and obtain communication network data for analyzing or evidence object.Such data are generally made up of signaling or network management information, or in example still less by the Composition of contents of communicating by letter.One of basis of LI is that law enforcement agency (LEA), management or regulator and intelligence department intercept and capture telecommunication according to local law.In some legal systems,---particularly real time access content---may need due procedure and receive proper authorization from competent department---that this activity was called as in the past " eavesdropping " and just existed since electronic communication beginning to implementation.
The problem of RAN high-speed cache and LI is must likely intercept and capture user plane traffic and may mode detect that flow is intercepted and captured without any.A solution can be that definition is for intercepting and capturing the new interface of object.But due to the cost relating in standardisation process and complexity, this is not regarded as a kind ofly proposing standardization for intercepting and capturing the feasible pattern of new RAN LI interface (for example, from RBS, RNC or BSC) of object.
Charge in mobile network is carried out by different core net and serving network node.Charge can be divided into online charging and off-line charge.The problem of RAN high-speed cache and charge is that user plane traffic is based on quantity, monthly record and content-based charge, for example uses according to the fees policy of URL, and in the time being cached at below core net, in RAN, can not be that given subscriber (or user) triggers charging function from RAN node at present.A reason is not to be that all mobile systems allow user's subscriber identification in RAN, to can be used for charging function.Also be this situation for LI function, not always likely in RAN, identify terminal use or subscriber.

Embodiment
In brief, be provided for the network node of use and the example embodiment of method of the high-speed cache in subscriber's rank control RAN.Particularly, network node comprises: the hereinafter referred to as RAN network node of RAN node and the CN network node that is called CN node.RAN node can be radio network controller (RNC) according to used RAT; Base station controller (BSC), radio base station, for example RBS, e Node B or eNB, Node B, donor base station or RAN controller node.For example, in UMTS/UTRAN/HSPA or GSM, RAN node can be RNC, BSC or any suitable controller node that is positioned at RAN.In LTE/E-UTRAN, RAN node can be eNB, or another RAN controller node, because LTE/E-UTRAN does not use RNC.
CN node can be mobile management entity (MME), gateway (S-GW), service universal grouping wireless electricity serving GPRS support node (SGSN), MSC, home subscriber system (HSS) or attaching position register (HLR).For example, in UMTS/UTRAN or GERAN or GSM or HSPA, CN node can be HLR/HSS or SGSN or MSC, and in LTE/E-UTRAN, CN node can be HSS or MME.
Before describing the heterogeneous networks scene of implementing this paper embodiment, first describe and illustrate the key step that RAN node and CN node are carried out respectively.
Fig. 2 describes the main method step of being carried out by RAN node according to this paper embodiment.As shown in the figure, the method comprises: RAN node receives 201 signaling messages from CN node or from another RAN network node, and this signaling message comprises about the information of subscriber's profile that is exclusively used in subscriber; 202 information that receive of analyzing are to determine whether provide designator in the information about subscriber's profile; In the information receiving, provide designator and determine whether 203 allow subscriber to use the high-speed cache in RAN; And result based on definite is controlled the use of the high-speed cache in 204RAN.
Fig. 3 describe according to this paper embodiment carried out by CN node for making the RAN node can be in the main method step of the use of the high-speed cache of subscriber's rank control RAN.As shown in the figure, the method comprises: assembling 301 signaling messages, and this message comprises about the information of subscriber's profile that is exclusively used in subscriber; Comprising 302 designators about the information of subscriber's profile, this designator indicates whether to allow subscriber to use the high-speed cache in RAN; And send 303 message that comprise the assembling of designator to RAN node, to make RAN node can determine whether to allow subscriber to use the high-speed cache in RAN.
Subscriber's profile mark (SPID) about the information of subscriber's profile.SPID is also referred to as the RFSP of RAT frequency of selection priority (RFSP) index or reservation.SPID can be assigned to particular subscription and be stored in one or some CN nodes.For example, if SPID is stored in HSS, it is called the RFSP index of reservation.Subscription is assigned or is exclusively used in the subscriber with subscriber equipment (UE).Signaling between CN and RAN is by standardization.SPID usage example in radio base station is the specific collection that the SPID value of reception is mapped to the RAT/ carrier wave using as the special priority information towards UE.Another may use is the part as provided for radio resources management (RRM).RRM function relates to distributes and safeguards radio communication path and carried out by RAN.RRM strategy in E-UTRAN/LTE for example can be based on the specific information of user.
SPID is by the following RAN node that arrives.In the time having the UE of subscription and be attached to mobile network, subscription context is downloaded to CN node from another CN node, and when create UE context in RAN node time, sends SPID from CN node to RAN node by signaling.According to this paper embodiment, SPID is expanded further to comprise the designator that indicates whether to allow high-speed cache.This will help the judgement of RAN node to allow which subscriber to use high-speed cache.
As more early mentioned, according to this paper embodiment, RAN node determines for subscriber whether allow high-speed cache by the value that checks/determine designator, and if the value pointer of designator allows the high-speed cache in RAN to this subscriber, RAN node is for example controlled the use of high-speed cache by what relatively receive from subscriber for the request of information and the cache content providing the RAN high-speed cache associated with RAN node, and if the information of asking is in high-speed cache, RAN node allows subscriber to fetch asked information from high-speed cache.If but the value pointer of designator does not allow the high-speed cache in RAN to this subscriber, RAN is by control the use of high-speed cache to the request for information of expection server transmitting subscriber, or RAN node is to the high-speed cache signaling associated with RAN node: do not allow the high-speed cache in RAN for this subscriber.For example SPID can pointer to this subscriber: " 100=will allow to use high-speed cache ", " 101=will not allow to use high-speed cache ".If indicated value 100, relatively subscriber's the request for information and cache content, and if the content of asking in high-speed cache, it can return to subscriber from high-speed cache.If but indicated value 101, to expection server, for example internet or media server transmitting subscriber the request for information, rather than with cache content comparison.Notice that embodiment is not limited to above value 100 and 101.These values are design parameters.
Therefore, SPID is expanded to allow other as the high-speed cache logic in RAN or RAN node and/or the input for the treatment of circuit, in the time that the flow that judges which subscriber is allowed to high-speed cache as designator.
This mode likely at subscription level control RAN high-speed cache take according to whether allowing high-speed cache in RAN to enable CN function, such as LI, charge, policy control etc. as given subscriber.
For example, if activate LI or need specific tariff for the particular subscription type of certain subscriber in CN, wherein for example need the extra charge in CN for this particular subscription type, the SPID receiving from CN node at RAN Nodes can indicate for this subscriber and not allow RAN high-speed cache normally to work to guarantee CN function.Therefore, the operator of network can be used this point as the chance that only comprises high-speed cache for particular subscription type, for example can obtain extra charge for these particular subscription types.
Should be mentioned that in prior art 3GPP framework, conventionally the function of carrying out in mobile packet-based core networks, such as charge, LI, mobility and policy control, to be anchored and to pass gateway, for example GGSN/P-GW based on all user plane traffic, to can carry out its function, and as previously described, in the RAN of some mobile systems, there is no user's subscriber identification, the in the situation that of LTE RAN, be for example IMSI, this user's subscriber identification can be used for marking terminal user for charge or intercept and capture action in accordance with the law.Even these CN functions still can appropriately be worked but use in mobile system according to the solution of this paper embodiment, wherein this mobile system does not allow user's subscriber identification in RAN, to can be used for such function.In addition, method described above can be independent of used radio access technologies (RAT) and realize.
Following chapters and sections more specifically describe for different RAT how to transmit SPID from CN to RAN.
When Fig. 4 is shown in SPID and is used to refer to the high-speed cache whether allowing in RAN for the simplification framework of E-UTRAN/LTE situation.As previously described, transmit the RFSP index of SPID or reservation from HSS401 to MME402, it is translated or is converted to the RFSP index of the reservation in use in this MME.Even in other system, CN node is still translated SPID or convert to the RFSP index in use.For example, for UTRAN, SGSN carries out as by translating of schematically illustrating in Fig. 6, and for GERAN, MSC carries out and translates.
Get back to Fig. 4, MME402 receives SPID from HSS401 during UE attaching process, and in MME402, stores SPID.In the time that UE context is set up, MME402 forwards the RFSP index of SPID or reservation to RAN node eNB404.Should be mentioned that for roaming subscriber/UE, MME402 can analyze and removes or add SPID based on IMSI.Fig. 4 also illustrates gateway 407, is connected to grouped data network gateway (PDN-GW) and the gateway (S-GW) of internet.Also described the UE406 in the overlay area of E-UTRAN/RAN.
In E-UTRAN/LTE scene, below signaling message comprise SPID:INITIAL CONTEXT SETUP REQUEST(initial context set up request); UE CONTEXT MODIFICATION REQUEST(UE contextual modifications request); Comprise source eNB transmits container HANDOVER REQUIRED(requirement switching to target eNB) and HANDOVER REQUEST(handover request).
INITIAL CONTEXT SETUP REQUEST message can comprise following cell IE: the switching restriction list IE that can comprise roaming, region or restrict access; UE radio ability IE; For subscriber's profile ID IE of RAT/ frequency priority; Circuit switching retreats designator IE and SRVCC operation may IE.If available in MME, in this scene, be this situation, INITIAL CONTEXT SETUP REQUEST message should comprise the SPID IE for RAT/ frequency priority.This is equally applicable to UE CONTEXT MODIFICATION REQUEST.
Switching the situation of UE from source eNB to target eNB, transmit the SPID IE for RAT/ frequency priority from source eNB to target eNB by X2.Therefore, according to an embodiment and in the situation that switching, RAN node, for example target eNB are arranged in the signaling message that comprises SPID and receive SPID from source RAN, for example source eNB, and this SPID indicates whether to allow the UE switching to use the high-speed cache in target RAN node.
Return to Fig. 4, have SPID(or use in the RFSP index of reservation) eNB304 be arranged to the use of controlling the high-speed cache in RAN.High-speed cache 405 can be positioned in eNB404 or be connected to eNB404, or high-speed cache 405 can be positioned in RAN upwards higher height, for example be positioned over as shown in the figure (or being connected to RAN controller node 403) in RAN controller node 403.In the scene of Fig. 4, whether the signaling depending between MME402 and eNB404 passes through and has two sub-scenes via high-speed cache 405.In example subfield scape, SPID value is regarded as receiving from MME402 in the specific signaling connection of UE.Interface between MME and eNB is called S1-MME interface.In example subfield scape, the user plane between S1-U interface, i.e. eNB404 and gateway S-GW407 can be arranged to via high-speed cache 405 and pass through equally.
Scene 1: high-speed cache (not shown) is in eNB404
In this scene, eNB404 analyzes the message that comprises SPID value receiving to determine whether to allow high-speed cache to control the use of high-speed cache, judges whether to allow to use the UE406 of this subscription to use the local cache of (or being connected to eNB404) in eNB404.
Scene 2: high-speed cache 405 in RAN upwards higher height, for example, in RAN controller node 403:
In scene 2, there are two sub-scenes:
-subfield scape 2a:MME-eNB signaling interface S1-MME does not pass through via high-speed cache.
In this subfield scape, eNB304 uses the SPID value that receives to judge whether to allow to use the UE406 of this subscription to use in RAN the upwards high-speed cache of higher height.
If SPIC indication allows high-speed cache, eNB404 allows high-speed cache to high-speed cache signaling and indication.User plane between S1-U interface, i.e. eNB404 and S-GW407 can pass high-speed cache 405.If S1-U interface is for example via transmitting the configuration of network, through high-speed cache, eNB404 allows high-speed cache just enough to high-speed cache 405 signaling indications.
If SPID indication does not allow high-speed cache, eNB404 guarantees not use high-speed cache.A kind of is that eNB404 does not link S1-U interface to pass through via high-speed cache 405 for realizing the mode of this point.Another way is that eNB404 notifies to high-speed cache 405 signalings: do not allow high-speed cache for subscriber or UE406.An action after using in the situation that S1-U interface passes through through high-speed cache 405.Another mode is as previously described, and RAN node, in this example, to be eNB404 forward to expection (internet) server the request for information receiving from subscriber or UE406.
-subfield scape 2b:MME-eNB signaling interface S1-MME passes through via high-speed cache.
In this subfield scape, high-speed cache 405 can be intercepted and captured S1 Application Protocol (S1AP) signaling and detect from the SPID value of MME404 indication on S1-MME interface.Then high-speed cache 405 in RAN controller node 403 uses SPID value to judge whether allowing the to use UE406 of this subscription to use high-speed cache.Therefore, with the main difference of subfield scape 2a be in this subfield scape, eNB404 is without sending SPID values to high-speed cache 405 use signalings.ENB404 is arranged to and takes similar movement to pass through (in the situation that allowing high-speed cache) to guarantee S1-U interface via high-speed cache 405.
When Fig. 5 is shown in SPID and is used to refer to the high-speed cache whether allowing in RAN for the simplification framework of WCDMA/HSPA situation.Fig. 5 illustrates the CN that comprises HSS501, and this HSS is connected to SGSN502, and this SGSN is connected to again GGSN507.GGSN507 is connected to internet.In RAN or UTRAN, provide the RNC503 that is connected to Node B or NB504.UE506 is also shown.Fig. 5 also illustrates that high-speed cache 505 is parts of RNC, but this is optional.Hereinafter, be positioned at and where describe four kinds of scenes according to being cached in RAN.
Should be mentioned that in WCDMA, below signaling message comprise the public ID of SPID:COMMON ID(); DIRECT TRANSFER(directly transmits); RELOCATION REQUEST(re-positioning request), RELOCATION REQUIRED(requires reorientation) and RANAP ENHANCED RELOCATION INFORMATION REQUEST(RANAP strengthen relocation information request), all these message comprise that source RNC is to Target RNC transparent vessel, and this container comprises SPID.
In the time switching, utilize transparent vessel to transmit SPID from RAN to RAN.In the time of cell reselection, but UE changes community network not yet ' preparation ' target RAN node, CN node need to send new SPID.Need the SPID coordinating to encode to obtain identical UE behavior and no matter how UE arrives Target cell.
Return to Fig. 5, HSS501 and SGSN502 be treatment S PID as normal, and RNC503 or Node B or NB504 take the new element according to example embodiment.In all scenes, suppose that the user plane interface between Iu-PS UP interface, i.e. RNC503 and SGSN502 or GGSN507 is passed through via high-speed cache.Also suppose that UE506 is arranged to the request sending for information, for example media or data as previously described, and this information can be provided as cache content to allow UE506 so to do permission subscriber or UE506 in the time that high-speed cache is fetched.
Scene 1: high-speed cache 505 is (as shown in Figure 5) in RNC503
RNC503 is arranged to from CN node, this example, comprises the signaling message of the RFSP index in SPID or use for SGSN502 reception, and analyzes SPID to determine whether provide designator in SPID.If designator exists, RNC503 determines whether to allow high-speed cache in RAN, determines whether to allow to use the UE506 of this subscription to use the local cache in RNC503.In this case for Iu-PSUP interface without specific action because high-speed cache and interface the two all in same node point, in RNC503.
Scene 2: high-speed cache (not shown) in RAN upwards higher height, more than RNC503 but below CN/before.
The action of RNC503 can with previously about Fig. 4, " scene 2: high-speed cache 405 in RAN upwards higher height, for example, in RAN controller node 403 " describe the action of being taked by eNB404 very similar.S1-MME interface is called Iu-PS interface in this scene, and this Iu-PS interface is the control plane part of this interface also referred to as Iu-PC CP to indicate it.Two the sub-scene 2a and the 2b that more early describe about Fig. 4 are also suitable for here.
Scene 3: high-speed cache (not shown) is between RNC503 and NB or Node B 504.
In this case, RNC503 and high-speed cache are without having new signaling interface.When RNC503 is when SGSN502 receives the SPID value signaling message, this SPID value is forwarded to high-speed cache.High-speed cache (or RNC) can use the value of reception to judge for connecting associated UE506 with this signaling whether allow high-speed cache.Note owing to being cached in RAN, so also it is considered as to RAN node here.
Scene 4: high-speed cache (not shown) is in NB or Node B 504.
When RNC503(is in signaling message) while receiving SPID value from SGSN503, this SPID value is forwarded to NB504.Then NB504 is arranged to and uses the SPID value receiving to determine/to judge for connecting associated UE with this signaling whether allow high-speed cache.
Above scene 3 and 4 needs additional measures really, because the high-speed cache below RNC is conventionally unlikely because air-interface encryption stops in RNC.But, will between RNC and Node B, move or even move in Node B if encrypt terminating point, these scenes are also effective scenes.
Fig. 6 illustrates network scenarios, and this network scenarios comprises multiple RAN of different RAT, is connected respectively to the E-UTRAN of CN node M ME, SGSN and MSC; UTRAN and GERAN, can implement example embodiment of the present invention therein.It should be noted that high-speed cache is not suitable for circuit switched service (for example voice).But for example, can be arranged to RAN node, for example send the SPID that comprises designator to GERAN node or to UTRAN node or to E-UTRAN node as the MSC of circuit switching (voice) node, and RAN node is used for described SPID to control the high-speed cache of RAN for packet-switched services/flow.In simplification scene, also illustrate that the SPID in different nodes processes.For example, as previously, in conjunction with as described in Fig. 4 (E-UTRAN/LTE scene), HSS and MME processed the SPID in CN, and RAN node from from MME to E-UTRAN sends SPID by signaling.As previously described, be stored in the RFSP index that SPID in HSS is called reservation, and subsequently respectively at MME; In SGSN and MSC, it is translated.This point shown in Figure 6.
Similarly, for UTRAN/WCDMA/HSPA, HSS and SGSN/MSC process the SPID that the RAN node signaling from SGSN/MSC to UTRAN sends.For GERAN, SPID is processed and is sent to the RAN node in GERAN by signaling subsequently by HSS and SGSN/MSC.
Switching UE(or subscriber's (not shown) from source RAN to target RAN) in the situation that, between RAN, in suitable signaling message, transmitting SPID or RFSP index as shown in Figure 6.For roaming subscriber, MME can analyze and removes or add SPID based on IMSI.
