Abstract
The invention includes steps: mobile terminal reports capability of the terminal for initiating the leaving resource in advance to network side; based on the said capability, the network side decides the initiator of leaving resource in advance; after deciding the initiator, the network side indicates the mobile terminal whether to initiate leaving resource. The invention avoids failure of the leaving resource procedure caused by that the mobile terminal does not possess capability for initiating the leaving resource as well as avoids both of mobile terminal and network side initiate the leaving resource pointed to a media stream.
Description
Technical field
The present invention relates to wireless communication field, especially relate to the method for determining the resource reservation initiator in a kind of network, the method, system and device that trigger resource reservation.
Background technology
WiMax (micro-wave access global inter communication) is the standard of broadband wireless access, is a kind of technology of the wireless MAN based on 802.16 standards, and it can provide towards the high speed of the Internet and connect.Different with current 2G, 3G technology, WiMax is a kind of completely based on the network of IP packet-switch technology, and the circuit-switched technology towards voice is not provided, and therefore, must adopt the form of VoIP in the enterprising lang sound communication of WiMax network.802.16e be 802.16 standards under the mobile environment.
Owing to need in the WiMax network, carry multiple business, as voice, video, HTTP, Email or the like, and miscellaneous service is to the requirement difference of service quality (QoS), as bandwidth, delay, packet loss etc., need hang down delay as video flowing, but can tolerate certain packet loss, the Email business then allows higher delay, but requires extremely low packet loss and error rate.Therefore in the WiMax system, need the support of realization to QoS, promptly to the different business data of same portable terminal (MS/MSS/SS), different service flow (service flow) is provided, as the service flow of a VOIP, the service flow of a HTTP, and different service flow is specified different qos parameters, thereby guarantee for different business provides different service quality.Usually, when certain business of the needs WiMax network carrying, MS or network side can be initiated resource reservation, satisfy this professional resource to provide at Access Network, and said here resource can comprise the resource and the access network resources of air interface.
In current NWG (network work group) draft, the WiMax network reference model as shown in Figure 1.The WiMax network mainly is made up of three parts, i.e. client (MS/MSS/SS), access service network (ASN) and connection service network (CSN).Wherein, ASN comprises base station (BS) and access service network gateway (ASN GW) etc., and CSN comprises prepaid server (PPS), 3A server functional entitys such as (AAA Server) again.
In the current NWG draft, the QoS reference model of WiMax as shown in Figure 2.In WiMax QoS framework, have with the closely-related entity of the present invention:
Management service flow device (SFM:Service Flow Management) always is arranged in the base station of ASN, according to the situation of local wireless sources and local other resource, service flow is carried out access control.
Service flow mandate (SFA:Service Flow Authorization) comprises service SFA (servingSFA) and anchor point SFA (anchor SFA), can approve service flow according to local policy.
Policing feature body (PF:Policy Function) is grasped user profile and to its entity that qos policy is provided, is arranged in CSN.PF can be divided into the PF of home network, i.e. the PF of H-PF, and visited network, i.e. and V-PF, this paper is referred to as PF.
Application function body (AF:Application Function), user terminal MS is directly mutual by application layer protocol and AF, as by SIP (Session Initiation Protocol, Session initiation Protocol) agreement, and AF is can be with PF mutual and trigger PF and initiate resource reservation.AF can be divided into the AF of home network, i.e. the AF of H-AF and visited network, i.e. and V-AF, this paper is unified into AF.If IMS (IP Multimedia System) territory, then AF is P-CSCF.
The 3A server (AAA:Authentication, Authorization Accounting), are arranged in the server of CSN, be used to provide to the user authenticate, the function of authentication, charging.
It should be noted that Fig. 2 is the QoS frame diagram of portable terminal under roam mode, when portable terminal under non-roaming pattern, ASN will directly be connected with home network services provider (H-NSP), and without access network services provider (V-NSP).
Two kinds of modes of initiating resource reservation request in the WiMax/802.16 network, have been defined, i.e. the resource reservation that the resource reservation of MS initiation and network side are initiated.
The resource reservation request reference flowchart that MS initiates in the current WiMax network is (this paper is called for short the PD process) as shown in Figure 3.As shown in Figure 3, the resource reservation that MS initiates is finished by strategy decision (PD:Policy Decision) message, comprise strategy decision request PD-Request message and strategy decision response message PD-Response, note, wireless air interface between MS and SFM is that (interface-free resources of 802.16 definition is reserved series message to DSX message, comprise that dynamic service flow sets up DSA, dynamic service flow is revised related news such as DSC and dynamic service flow deletion DSD).PD-Request message finally sends to policing feature body PF, ratifies or refuse this request by PF.
The resource reservation request that network side is initiated can be initiated by PF or SFA, and the resource reservation that SFA initiates is at prefabricated Business Stream, not within this paper discussion scope, and reference flowchart such as Fig. 4 (this paper is called for short the RR process) of the resource reservation request that PF initiates:
As shown in Figure 4, the resource reservation process that network side is initiated is by RR (Resource Reservation, resource reservation) message is finished, comprise resource reservation request message RR-Request and resource reservation response message RR-Response, equally, the wireless air interface between MS and SFM is a DSX message.The resource reservation process that network side is initiated can be triggered by application function body AF.
When MS enters network for the first time, the MS that 802.16 definition can take place goes into network process, this process comprise scanning with simultaneous downlink, obtain downstream parameter, obtain line parameter, initial ranging, basic capability negotiating, authentication and authorization, register, set up IP and be connected or the like, in this process after MS has passed through authentication and authorization, MS can send login request message REG-REQ to register to network to network side, REG-REQ message can report some abilities of MS to give network side, and this process makes that MS can accesses network.After BS receives the REG-REQ message that MS sends, some parameters in the REG-REQ message can be passed to ASN GW by context request (Context-Request) message, as the ability of convergence sub-layer CS etc.SFA can send SFA position updating request SFA-LU-REQ message to H-PF (SFA-LU-REQ message can send to H-PF through V-PF) in this process, to finish the position updating process of SFA, and can be with reference to routine as shown in Figure 5 flow process.
Session Initiation Protocol and the IP Multimedia System (IMS) that again the present invention be will be referred to simply introduced below.
Session Initiation Protocol is to be organized in proposed in 1999 one in IP based network by IETF, particularly in the network environment of a kind of like this structure of Internet, realizes a kind of signaling protocol that real-time communication is used.And so-called session (session) just is meant the exchanges data between the user.In application based on Session Initiation Protocol, each session can be various data, can be common text data, also can be audio frequency, video data through digitized processing, can also be to wait the data of using such as recreation, application has very high flexibility.
Standard as an IETF proposition, Session Initiation Protocol has been used for reference the Internet agreement of other various extensive existence to a great extent, as http (HTML (Hypertext Markup Language)), SMTP (Simple Mail Transfer protocol) etc., the same with these agreements, the text based coded system that SIP also adopts, this also is that Session Initiation Protocol is compared one of maximum characteristics with other existing standards of video communication field.
The SIP core specification has defined 6 kinds of SIP requests, each all has different effects, wherein register requirement (REGISTER) message is used for the contact address of sip user agent to registrar registration oneself, and INVITE (invitation) message is used to invite the callee to add a session.
The message format such as the table 1 of SIP request comprise request row, title head, null and message body (request row and title head part are only as example):
Table 1.
| Request row Request-line | Comprise: method, request-URI, protocol version INVITE sip:bob@biloxi.com SIP/2.0 |
| Title head Several headers | Via：SIP/2.0/UDP?pc33.atlanta.com；branch＝z9hG4bK776asdhds To：Bob<sip:bob@biloxi.com> From：Alice<sip:alice@atlanta.com>；tag＝1928301774 Call-ID：a84b4c76e66710@pc33.atlanta.com Contact：<sip:alice@pc33.atlanta.com> Content-Type：application/sdp |
| Null Empty line | |
| Message body Message body | As media description or out of Memory such as SDP, there is not message body in some SIP request |
User's SIP public user identity is the disclosed contact address of user, adopts the form that is similar to e-mail address, as user_name@domain_name.When the user need arrive certain registrar registration, can send the REGISTER request to registrar, this request comprises user's public user identity and current actual contact address, therefore after user registration success, can keep user's the public user identity and the binding relationship of current actual contact address on the registrar, so other user can relate to the user by registrar.
When the user need invite certain called subscriber to participate in certain session, wish voice communication as caller with the called VoIP of carrying out, then the calling party can send the INVITE request to the callee, usually, the INVITE request can be related to the callee at last by one or more sip servers (as acting server).
The SIP core specification defines in RFC3261, yet the SIP of core specification definition is limited in one's ability, therefore for the demand of those special applications, can realize the expansion on the SIP function by the form of SIP expansion.
IMS (IP Multimedia System) is the 3G network core technology standard that 3GPP formulates at first, at present by ITU-T and ETSI approval, include the core standard framework of NGN in, IMS has proposed the design concept that carrying and control are separated, and is considered to realize not fix/important technology that the mobile network is merged.IMS has proposed the complete IP network framework, adopts Session Initiation Protocol as the control signaling, realizes mobile management, Multimedia session signaling and bearer services transmission, realizes IP operation end to end.
CSCF (CSCF) is the calling control core of IMS system, angle from Session Initiation Protocol, CSCF is then serving as the function of sip server, CSCF can be subdivided into P-CSCF from the function logic, I-CSCF, S-CSCF, wherein P-CSCF (proxy CSCF) is first access point of IMS system, be used for call request is acted on behalf of to I-CSCF (inquiry CSCF) or portable terminal, and P-CSCF finishes the function of AF, be about to dynamic QoS related application layer parameter such as SDP and be mapped as decision-making and set up information, and send PDP (Policy Decision Point policy decision point) to.I-CSCF mainly is responsible for to HSS inquiry home subscriber information, with the registration message of MS with call out correct route to S-CSCF.The function that S-CSCF (serving CSCF) also serves as registrar, control and processing capacity are called out in the receiving terminal registration, and to the application server AS trigger intelligent business.
IMS is a core key-course, and the Access Network that inserts IMS can be any IP network, as 3G network, WLAN, ADSL and WiMax etc.Because many network integrations are development trends of future communications system, so the WiMax standard also can provide support to inserting IMS.The WiMax standard does not define the system architecture that inserts the IMS system at present, when WiMax inserts IMS, AF can be the P-CSCF among the IMS, and PF possibly extended function perhaps have interface to communicate between the PDF in PF and 3GPP/IMS territory with the function of the PDF that possesses 3GPP/IMS definition; If the R7 framework that adopts 3GPP to formulate, then PF has interface communication between PCRF or PF and the PCRF.
The IMS standard is formulated by 3GPP, and adopt SIP as the control signaling, in the SIP signalling interactive process between MS and IMS (as Fig. 6), P-CSCF (AF) meeting and PDF (strategy decision functive) communicate with authorized token (Authorization Token), and P-CSCF can issue MS with this authorization token in mailing to the SIP signaling of MS, this token carries in SIP extension header P-Media-Authorization.The 3GPP Access Network can carry out resource reservation by PDP context activation subsequently, and MS need show this authorization token to network in PDP context activation.Authorization token shows that network side authorizes the Media Stream that application layer signaling (as SIP) is consulted, and therefore one does not have the resource reservation request of authorization token to be refused by network.What deserves to be mentioned is in the up-to-date PCC framework of 3GPP, charging rule functions CRF and strategy decision function PDF have been merged into a functive PCRF, so PCRF to possess the function of policy decision point PDP.Authorization token mechanism is the licensing scheme that adopts in the 3GPP R6 framework, and in R7 PCC framework, still needs authorization token mechanism is carried out compatibility.
Usually, the resource reservation process of WiMax network should be triggered by the functive of application layer, and the entity that can trigger comprises MS and AF, and before initiating resource reservation, MS and AF can consult media parameter.Application layer can be shone upon QoS after obtaining professional QoS attribute to bottom QoS.
Current WiMax standard is pointed out the mode of two kinds of resource reservation of WiMax network support, i.e. the resource reservation (for example, foregoing resource reservation RR process and strategic decision-making PD process) that the resource reservation of MS initiation and network side are initiated.
Current WiMax standard is pointed out the resource reservation process that WiMax network and the necessary compulsory support of MS are initiated by network, and a MS can possess the ability of initiating resource reservation, but and does not require that MS must possess the ability of initiating resource reservation.Therefore a MS might possess the ability of initiating resource reservation, also may not possess the ability of initiating resource reservation.Yet the WiMax network does not also know whether certain MS possesses the ability of initiating resource reservation.So, will produce two problems:
1) the WiMax network does not know whether a MS possesses the ability (if a MS possesses the ability of initiating resource reservation, then software on the MS or hardware need provide support to this) of initiating resource reservation.If network side requires MS to initiate resource reservation, and MS does not possess the ability of initiating resource reservation, then resource reservation can not carry out, as Fig. 7.
2) MS and network side might occur and all initiate the scene of resource reservation at same business, then might be at same professional two parts of resources of reserving, perhaps produce waste on conflict, the resource, unusual etc., as Fig. 8.
Summary of the invention

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, specific embodiments of the invention are elaborated below in conjunction with accompanying drawing.
Below only with the 802.16/WiMax network be example the present invention will be described, but the present invention is not limited to the 802.16/WiMax network, and can be applied to other similar network equally.
Embodiment 1
The ability that the embodiment of the invention 1 reports this MS to initiate resource reservation by MS to network side solves the WiMax network and does not know whether MS possesses the problem of the ability of initiating resource reservation.Can be listed below 2 kinds of execution modes at this.
Mode 1: the message by expansion 802.16/WiMax realizes that MS initiates reporting of resource reservation ability.
Fig. 9 reports the process schematic diagram of initiating the resource reservation ability for MS in the present embodiment.As shown in Figure 9, in the MS registration process, can initiate the PF (comprising the PF of visited network and/or the PF of home network) that ability that the information of the ability of resource reservation initiates resource reservation with MS reports network side by in REG-REQ message, Context Request message, SFA-LU-REQ message, carrying instruct MS.
Particularly, can be in REG-REQ message, Context Request message, SFA-LU-REQ message newly-added information element (IE): " MS Resource Reservation Initiation Capability ", be used for instruct MS and initiate the ability of resource reservation, can know that after PF receives SFA-LU-REQ message MS initiates the ability of resource reservation; This IE also can comprise in REG-RSP message, Context Response message, SFA-LU-RSP message.
Mode 2:MS reports network side by the application layer signaling with the ability whether MS can initiate resource reservation.
Be that MS reports MS to initiate the ability of resource reservation by the indication information that carries MS initiation resource reservation ability in the application layer signaling to the application function body (AF) of network side, after network side learns that MS initiates the ability of resource reservation, can whether support the ability of initiating resource reservation to determine whether to trigger MS initiation resource reservation according to MS, promptly after network side (AF) learnt that MS possesses the ability of initiating resource reservation, network side (AF) can trigger MS and initiate resource reservation; Learn MS when network side (AF) and do not possess the ability of initiating resource reservation that then network side (AF) can not trigger MS and initiate resource reservation.
Consider that the application layer protocol kind is a lot, present embodiment is that specific embodiment describes with the Session Initiation Protocol with wide application prospect, and when operation Session Initiation Protocol in the WiMax network, AF then possesses the function of a sip proxy server.
The mode 2 of present embodiment 1 has been expanded existing Session Initiation Protocol, by carry out increasing an expansion in SIP register requirement (REGISTER) message in when registration at MS, the ability indication that this expansion is responsible for MS is initiated resource reservation sends to network side (AF), as shown in figure 10.Expansion can realize with the prolate-headed mode of newly-increased SIP, also can realize by the mode that increases parameter in existing SIP title head.
For example, use newly-increased SIP extension header can adopt following implementation:
P-MS-RR-Init-Capability：Yes/No
Above expanding packet is contained in the SIP register requirement REGISTER message that MS mails to AF and sends, be used to represent whether MS possesses the ability of initiating resource reservation, the possible value of this expansion can comprise: Yes and No (but are not limited to this, also can be 1/0 etc., as long as can be used in the ability that instruct MS is initiated resource reservation).
Implementation by newly-increased parameter in existing SIP title head:
For example, can be used for instruct MS and whether possess the ability of initiating resource reservation by newly-increased parameter MS-RR-Initiation-Capability in the Contact in the SIP login request message, this parameter is defined as follows:
MS-RR-Init-Capability＝Yes/No
The value that this parameter is possible is Yes and No (but being not limited to this);
This parameter is included in the Contact of REGISTER request:
Contact:＜sip:user_name@domain_name 〉; MS-RR-Init-Capability=" yes " is used to show that MS supports to initiate resource reservation;
Contact:＜sip:user_name@domain_name 〉; MS-RR-Init-Capability=" no " is used to represent that MS does not support to initiate resource reservation.
By the SIP signaling of expansion, network side (AF) can access the information whether MS possesses the ability of initiating resource reservation.Consider that MS can periodically send heavy register requirement, therefore above-mentioned expansion can only send in first register requirement.
Further, when expanding by SIP, AF this ability can be informed that by the interface message between AF and the PF/PDF/PCRF policy decision point PF/PDF/PCRF (considers the fusion of WiMax and IMS after the ability that obtains MS initiation resource reservation is indicated, may have PDF functional entity or PCRF functional entity between AF and the PF), as shown in figure 11.
By as above scheme, network side AF and PF can obtain the ability information that MS initiates resource reservation, therefore can prevent because of MS can't initiate resource reservation and make the situation of service fail.
Embodiment 2
In addition, for fear of MS and network side same business is all initiated resource reservation, cause the conflict or the wasting of resources etc., the present invention proposes a kind of AF and triggers the method that MS initiates resource reservation by the application layer signaling, be after AF determines the resource reservation initiator, comprise the indication information whether instruct MS initiates resource reservation in mailing to the application layer signaling of MS, whether MS initiates resource reservation according to this information decision.
Equally, the present invention is that embodiment 2 describes with the Session Initiation Protocol, but the present invention is not limited to this.Network side can comprise following several to MS notice resource reservation initiator's mode:
Mode 1:MS determines whether to initiate resource reservation (as Figure 12) by whether carrying authorization token in the SIP signaling.
In 3GPP, authorization token is obtained from PDF by AF (P-CSCF), be used for the mandate of network to Media Stream, whether the mode 1 of present embodiment 2 has expanded the function of authorization token, promptly contained authorization token and determine that initiating resource reservation by network side still is to initiate resource reservation by MS by protecting in mailing to the SIP signaling of MS by AF; MS determines whether to initiate resource reservation according to whether comprise authorization token from the SIP signaling that AF receives.
When policy decision point PF/PDF/PCRF decision is initiated resource reservation by network side, PF/PDF/PCRF can not produce authorization token to AF, AF can not comprise authorization token in mailing to the SIP signaling of MS, MS can not get authorization token thus, then can not initiate the resource reservation process, resource reservation is initiated by network side PF/PDF/PCRF.
When the PF/PDF/PCRF decision is initiated resource reservation by MS, PF/PDF/PCRF produces authorization token and also passes to AF, and AF can comprise authorization token in mailing to the SIP signaling of MS, and MS can authorized token thus, then initiate the resource reservation process, and network side can not initiated the resource reservation process.
Whether mode 2:MS initiates resource reservation (as Figure 13) by the particular value decision of definition authorization token.
In this programme, AF always obtains authorization token from PF/PDF/PCRF, and is handed down to MS in the SIP signaling.Different is, when the PF/PDF/PCRF decision is initiated resource reservation by network side, then produce the authorization token of particular value, be set to complete 0 or complete 1 as the authorization token that produces, MS then can initiatively not initiate resource reservation when receiving the authorization token of this particular value from the SIP signaling from AF, and PF/PDF/PCRF can initiate resource reservation from self after producing the authorization token of this particular value; When the PF/PDF/PCRF decision was initiated resource reservation by MS, PF/PDF/PCRF produced the authorization token of non-particular value and gives AF, when MS receives this authorization token from the SIP signaling from AF, then can initiatively initiate resource reservation.
Mode 3: whether initiate resource reservation (as Figure 14) by the newly-increased SIP expansion notice MS that carries the resource reservation initiator information.
The manner is issued newly-increased following SIP extended message head in the INVITE of MS and the response message thereof at AF:
P-RR-Initiator：MS/Network
In this scheme, AF can obtain resource reservation initiator's information from PF/PDF/PCRF, and comprises this information in above-mentioned extended message head.P-RR-Initiator extended message head is included in the response message that AF issues the INVITE of MS or INVITE, when the P-RR-Initiator value is MS, show that the resource reservation initiator is MS, MS can be by initiating resource reservation process, i.e. PD process after receiving this expansion; When the P-RR-Initiator value is Network, show that the resource reservation initiator is network side, then MS can not initiate the resource reservation process after receiving this expansion, and resource reservation is initiated by network side.
Embodiment 3
In order to realize as above method, definite resource reservation initiator's of the embodiment of the invention 3 system mainly comprises: portable terminal, policy decision point and application function body AF, as shown in figure 15, wherein
Described portable terminal is used for reporting this terminal to initiate the ability of resource reservation to network side;
Described policy decision point (as PF/PDF/PCRF) is positioned at network side, is used for the ability decision resource reservation initiator according to the initiation resource reservation of terminal to report, and gives application function body AF with the result notification of decision; And
Described application function body AF is positioned at network side, is used for indicating described portable terminal whether to initiate resource reservation according to the result of policy decision point decision.
The device of the network side in the described system comprises policy decision point and application function body AF, and wherein policy decision point (as PF/PDF/PCRF) is the decision unit, to initiate the ability decision resource reservation initiator of resource reservation according to terminal; Application function body AF is an indicating member, is used for indicating mobile terminal and whether initiates resource reservation.
In sum, in the embodiment of the invention, MS is by reporting the ability information of oneself initiating resource reservation to network side, make the initiator of definite resource reservation that network side can be correct, thereby avoided MS not possess when initiating the resource reservation ability and the resource reservation procedure failure that causes;
And, after network side is determined the resource reservation initiator, notice MS, whether MS need initiate the resource reservation process with notice, perhaps also can be only when the network side decision be initiated resource reservation by MS, notice MS initiates process with the resource reservation that triggers MS.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.Within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
