Description
Technical field
The present invention relates to communication field, and especially, relate to a kind of implementation method of multi-registration.
Background technology
IP Multimedia System (IP Multimedia Subsystem, IMS) be third generation affiliate tissue (3rd Generation Partnership Project, abbreviation 3GPP) standard of the next generation network of definition, its distinguishing feature is to have adopted Session initiation Protocol (Session Initiation Protocol, be called for short SIP) system, make that communication and access are irrelevant, and can possess multiple media business controlled function separates with bearing capacity, calling separates with session, application separates with service, business and network detach, and multiple abilities such as mobile network and internet integrated services, therefore, the trend of communication network fusion development has been complied with in the proposition of IMS.
Major function entity in the IMS system comprises: call conversation control entity (the Call Session Control Function that functions such as user's registration management, session control are provided, be called for short CSCF), home subscriber server (the HomeSubscriber Server of centralized management user contracting data function is provided, be called for short HSS), the application server (Application Server is called for short AS) of miscellaneous service logic control function is provided.
Fig. 1 show the main network element entity of IMS architecture and between connect each other.Wherein: the terminal equipment that subscriber equipment (User Equipment is called for short UE) 101 representative of consumer are used; CSCF (Call Session Control Function, abbreviation CSCF) entity is the core network element of control conversation procedure, it comprises: Proxy Call Session Control Function (Proxy-CSCF, be called for short P-CSCF) 102, query call conversation control function (Interrogating-CSCF, be called for short I-CSCF) 103, service call conversation control function (Serving-CSCF is called for short S-CSCF) 104; Home subscriber server (HomeSubscriber Server is called for short HSS) the 105th, the main storage server of all data relevant among the IMS with user and server; Application server (Application Server is called for short AS) 106 provides the network element of increment multimedia service.
Between each network element illustrated in fig. 1, UE links to each other with P-CSCF by Gm; Realize interconnected by Mw between P-CSCF, I-CSCF, S-CSCF; HSS links to each other with I-CSCF, S-CSCF by the Cx interface realization, realizes linking to each other with AS by Sh interface; S-CSCF realizes linking to each other with AS by the professional control of IMS (IMS service control,, be called for short ISC) interface.
The user is after signatory with operator, all possesses a public address (PublicAddress, be also referred to as Address of record, be called for short the AOR address), but the user can not directly carry out business with this AOR address, and need bind contact address (Contact Address) afterwards by registration, just can carry out normal business.In addition, the user is before using IMS registration business, also need carry out authentication at network, so the user is before using regular traffic, necessary successful execution registration process realizes that the user inserts the IMS network, the user at the basic procedure of IMS network registry as shown in Figure 2, should be noted that because the present invention does not relate to network elements such as I-CSCF, AS, HSS, so omitted the handling process of these network elements hereinafter.
As shown in Figure 2, the basic procedure of user's registration comprises following processing:
S201, UE sends register requirement to P-CSCF, comprises header fields such as Request-URI, From, To, Call-ID, CSeq in this request at least;
S202, P-CSCF is transmitted to S-CSCF with register requirement;
S203, S-CSCF returns the response of succeeding in registration to P-CSCF after UE and S-CSCF have finished the registration process of UE, comprise header fields such as From, To, Call-ID, CSeq at least in the response of succeeding in registration; Registration process may comprise challenge request, the adjustment response of UE initiation and the associative operation of HSS etc. that S-CSCF initiates;
S204, P-CSCF transmit the registration response and give UE, and UE has finished the registration at the IMS core network thus.
In registration process, UE and IMS core network come identifier register by the combination of From, To and call identification (Call-ID), owing to there be not the third party to help under the situation that the user registers, the value of From and To generally all is user's AOR address, and therefore different registrations are mostly to be to adopt Call-ID to identify.At present, Call-ID adds that by one section word string that generates at random each produces the special sign that adds and forms usually.
In the prior art, if From, To are identical but Call-ID is inequality, then the registration from same terminal will cover mutually, that is, after S-CSCF receives a back register requirement, existing registration before will covering, as shown in Figure 3, its basic procedure is as follows:
S301, UE send first register requirement to P-CSCF, and From, To header field value are the AOR of UE in the request, and the value of Call-ID header field is Call-ID1;
S302, P-CSCF transmit this register requirement and give S-CSCF;
S303, S-CSCF finish the registration process of UE, and its flow process is identical with S203, finish registration after, S-CSCF puts this UE state and is the state of succeeding in registration, simultaneously S-CSCF returns the response of succeeding in registration to P-CSCF;
S304, P-CSCF transmit the response of succeeding in registration and give UE, and UE has finished the registration at the IMS network, are called registration one here;
S305, UE send second register requirement to P-CSCF, and From, To header field value are the AOR of UE in the request, and the value of Call-ID header field is Call-ID2, and the value of Call-ID2 and the value of Call-ID1 are inequality;
S306, P-CSCF transmit this request and give S-CSCF;
S307, S-CSCF finds that this UE succeeds in registration, and the Call-ID value that monitors second Call-ID header field value in the register requirement and registration one is also inequality, so if this succeeds in registration, its log-on message will cover the log-on message of registration one, and nullify registration one and discharge and register a relevant Session Resources; S-CSCF finishes the registration process of UE, and S-CSCF returns the response of succeeding in registration to P-CSCF simultaneously;
S308, P-CSCF will succeed in registration to respond and be transmitted to UE;
S309 carries out network-initiated deregistration, nullifies registration one, and discharges the relevant Session Resources of registration.
As seen, the login mechanism of prior art has guaranteed that a UE can only have one to be registered in the IMS network effective simultaneously.
But, along with the development of IMS and the introducing of new business, circuit commutative field can be inserted IMS territory, the business that makes the circuit commutative field user can use the IMS territory to provide, thereby can guarantee user experience and professional continuity, can make the circuit commutative field user enjoy IMS new business simultaneously.Therefore, in 3GPP Release8, introduced IMS centralized traffic (IMS Centralized Services, be called for short ICS) technology, provide consistency, successional business service the user of different input fields.For these new introducings, all need to allow the single or a plurality of terminals of a contracted user, and be linked into individually or simultaneously in the same IMS core net by different access waies, form a plurality of different contact address corresponding to same user binding.
Like this, in some cases, UE wishes registration when repeatedly registration realizes a plurality of contact address, just has a plurality of effective registrations simultaneously, and being called as in this article is many registrations or multi-registration.This and existing login mechanism are disagreed, and just existing login mechanism can't carry out many registrations.For many registration problems, present the Internet engineering duty group (Internet Engineering Task Force, abbreviation IETF) tissue has also carried out big quantity research, provide employing outbound mechanism to realize, but its process more complicated, bigger to the existing procedure modification, be unfavorable for seamlessly transitting from prior art.At present, do not propose to realize simple and effective many registration realization technology as yet.

Embodiment
In the present embodiment, provide a kind of implementation method of multi-registration, be used for realizing at IP Multimedia System the multi-registration of terminal, wherein, multi-registration is meant the registration of a plurality of contact addresses that terminal is initiated.Fig. 4 is the flow chart according to the implementation method of the multi-registration of the embodiment of the invention.
As shown in Figure 4, the implementation method according to the multi-registration of the embodiment of the invention comprises: step S402 receives the multi-registration request at the IP Multimedia System network; Step S404, request is registered terminal according to multi-registration, and before the terminal under the situation of IP Multimedia System network registry, the log-on message before keeping, wherein, carrying this register requirement of expression in the multi-registration request is the beacon information of multi-registration request.
According to technique scheme, specifically may further comprise the steps:
The first step, terminal or network will be in the register requirement of initiating in terminal be added following information: (a), the multi-registration request possesses certain or some identical features, and not each other a plurality of register requirement of multi-registration do not possess these features; (b), when register requirement is during from different network insertion IMS network, the access way of carrying in a plurality of register requirement of multi-registration is inequality each other;
Second the step, network is received register requirement, finish register flow path after, with information that comprise, that in the first step, add in this register requirement of network side preservation;
The 3rd step, after network is received register requirement, current whether registration of user that needs registration will be judged, if the user has registered and current register requirement is not that registration refreshes, then judge current register requirement whether with the existing multi-registration that is registered as, if multi-registration will carry out many register flow paths, otherwise, register according to existing procedure;
The 4th step, register when refreshing, require the registration refresh requests to possess identical sign-on ID symbol with former registration request, perhaps possess identical access way information.
Wherein, terminal is specially in the processing that register requirement is provided with sign: setup string in the call identification of multi-registration request or instance identification, and the character string that will be each other be provided with in the multi-registration request of multi-registration is identical or meet pre-defined rule, thereby with the identification information of character string as the multi-registration request, wherein, the registration of stack is simultaneous registration in the IP Multimedia System network each other.
And under the situation that call identification is setuped string, the IP Multimedia System network is preserved the random string that character string sets in advance in call identification as the binding information of endpoint registration.
On the other hand, under the situation that instance identification is setuped string, the IP Multimedia System network is preserved the fixed character string that character string sets in advance in instance identification as the binding information of endpoint registration.
Specifically, in a of above-mentioned first step information, information can be identical with certain part word string in call identification (Call-ID) the header field value in register requirement.Perhaps, Call-ID meets certain specific rule, also can identify this in Call-ID and be registered as multi-registration.And information also can be identical with certain part word string in instance identification (Instance-ID) header field in register requirement, and perhaps Instance-ID meets certain specific rule, also can identify this in Instance-ID and be registered as multi-registration; It is to be used to identify one group and to superpose each other/feature of the register requirement of many registrations in essence, and the register requirement that has this feature superposes/many registrations each other, otherwise, then be not stack/many registrations, and, to guarantee that also each superpose/registers the uniqueness of stack features more; A plurality of registrations of stack each other/many registrations are called the multi-registration group, and the registration in the same multi-registration group is multi-registration each other, and corresponding register requirement belongs to same multi-registration request group; This characteristic character string can be the random train that generates at random, also can be the word string that produces according to certain rule.
And first under the situation of IP Multimedia System network registry, terminal generates at random and setups string in terminal; Afterwards, under the situation of the registration before terminal need refresh, terminal is obtained character string, character string is arranged in the registration refresh requests or based on character string be arranged in the registration refresh requests with pre-defined rule generation new character strings and with new character strings; And under the situation of the registration before terminal need be nullified, regenerate and in register requirement, be provided with other random string.
Under the situation of the registration before terminal need refresh, further comprise: terminal is obtained pairing call identification of the registration that need refresh or instance identification, and call identification or the instance identification of obtaining is sent to the IP Multimedia System network by the registration refresh requests; IP Multimedia System network pair refreshes with the registration of call identification that receives or instance identification coupling.
In addition, insert the IP Multimedia System network respectively by a plurality of networks and initiate under the situation of multi-registration in terminal, for each multi-registration, in terminal or the terminal accessing IP multimedia sub-system network development process by way of the trusted network element will add that the beacon information as the multi-registration request sends to the IP Multimedia System network in the register requirement corresponding to the access way information of current access network.
Wherein, receive access way information after, the IP Multimedia System network is carried out the registration to terminal, and access way information is preserved as binding information.
And, under terminal need refresh situation corresponding to the registration of certain network in a plurality of networks, this method can further comprise: terminal is obtained the pairing access way information of this network, and the access way information of obtaining is sent to the IP Multimedia System network by the registration refresh requests; IP Multimedia System network pair refreshes with the registration of the access way information matches that receives.
Wherein, sending under the situation that adds access way information in the registration message at it by terminal, by in the terminal accessing IP multimedia sub-system network development process by way of the trusted network element access way information that adds is verified, under the incorrect situation of checking access way information, IP Multimedia System is deleted this access way information and is refused terminal and insert or revise this access way information.
Specifically, in the b information of the above-mentioned first step, access way information can be to add when initiating registration by terminal, and the network element that also can be carried out terminal access mode information by the network element of register requirement approach adds; When access way information is added by terminal, by on the register requirement path, by the network element of IMS network trust, the correctness of access way information is verified; When the network element checking access way information of IMS network trust is incorrect, the IMS network will be deleted access way information, perhaps use correct access way information substitution; Register requirement can be carried by existing header field or label, also can carry this information by adding header field or label.
In second step, it is the registration of feature that the IMS network receives with Call-ID/Instance-ID, and after finishing registration, when preserving the binding information of this registration, the Call-ID/Instance-ID information of preserving this registration simultaneously is as binding information; The IMS network receives the register requirement of carrying access way information, and after finishing registration, when preserving the binding information of this registration, the access way information of preserving this registration simultaneously is as binding information;
In the 3rd step, judge that whether current register requirement is registered in same multi-registration group with existing, adopts the method that illustrates in the above-mentioned first step to judge;
According to many register requirement flow process, will finish this registration, and keep existing registration, original registration such as is not nullified at operation, at this moment, will there be two registrations simultaneously in a terminal; Different contact addresses has been carried in these two registrations; Do not belong to same multi-registration group if judge current registration and existing registration, at this moment when finishing current registration, need yet, discharge related resources such as original registration respective session original Register Cancel; The user finishes after many registrations, and the log-on message of storing on S-CSCF will no longer be an infobit, but this user's register list;
In the 4th step, can use Call-ID/Instance-ID as the sign-on ID symbol, it is identical with the Call-ID/Instance-ID of original registration then to register the Call-ID/Instance-ID that refreshes; When the UE decision refreshes certain registration, at first need to obtain the Call-ID/Instance-ID of original this registration, then with the Call-ID/Instance-ID of this Call-ID/Instance-ID as the registration refresh requests; After S-CSCF received the registration refresh requests, the identical registration of Call-ID/Instance-ID in will searching Call-ID/Instance-ID and register refresh requests in this user's register list refreshed this log-on message then; When using access way information, when the IMS network is accepted register requirement, if this user's current state is a registered state, to judge in the registration of access way information that current register requirement is carried and binding whether have consistent access way information, if there is no, to carry out many register flow paths, otherwise, will refresh original registration or finish this registration, nullify original registration.
Below, will be illustrated technique scheme in conjunction with the accompanying drawings.
Example 1, the situation of general registration.
Fig. 5 is the signaling process figure according to the example 1 general registration of the embodiment of the invention.As shown in Figure 5, specifically comprise the steps:
S501, UE generates sign according to rule, and next, the multi-registration group word string of the registration that will initiate if do not carry out the registration of this multi-registration group before, then can generate at random, perhaps generates according to Else Rule, but needs to guarantee the uniqueness of this word string.If this multi-registration group has existing registration, then multiplexing original registration group word string; This word string is formed unique Call-ID with random train and other possible word string of this registration of sign;
The register requirement that S502, UE will comprise header field information such as From, To, Call-ID sends to the P-CSCF network element of IMS network;
S503, P-CSCF is transmitted to corresponding S-CSCF with register requirement;
S504, S-CSCF receive after this register requirement, judge that this user is the state of having not yet registered, and handle this register requirement, after finishing registration, return the response of succeeding in registration to P-CSCF, and comprise Call-ID word string content at interior log-on message in the S-CSCF preservation;
S505, P-CSCF will succeed in registration to respond and return to UE, finish the registration of UE at the IMS network.
Fig. 5 is the signaling process figure according to the example 1 general registration of the embodiment of the invention, owing to do not carry out many registrations, so flow process and flow process shown in Figure 2 are only had any different generating on the Call-ID word string, and main application of the present invention is embodied on the flow processs such as many registrations and many registrations refresh.If adopt Instance-ID to identify, will on intrinsic Instance-ID basis, generate new Instance-ID as multi-registration; If adopt access way information, when UE adds access way information in register requirement, also can add access way information by P-CSCF or other network, S-CSCF is after carrying out registration, and S-CSCF preserves and contains access way information at interior log-on message.
Example 2, the situation of many registrations.
Fig. 6 is the signaling process figure according to example more than 2 registrations of the embodiment of the invention.As shown in Figure 6, specifically may further comprise the steps:
S601, not in the IMS registration, UE generates Call-ID1 to current UE as yet, and its flow process is identical with S501, and UE sends the register requirement of carrying Call-ID1 and arrives P-CSCF;
S602, P-CSCF is forwarded to S-CSCF with register requirement;
S603, S-CSCF receives after this register requirement, judge that this user is the state of having not yet registered, and handle this register requirement, after finishing registration, return the response of succeeding in registration to P-CSCF, and comprise Call-ID1 word string content at interior log-on message in the S-CSCF preservation, this User Status also becomes login state;
S604, P-CSCF will succeed in registration to respond and return to UE, finish the registration of UE at the IMS network thus, and this example is called registration one with this registration;
S605, UE generated the Call-ID2 that belongs to same multi-registration group with registration one before initiating second register requirement, its product process is seen S501, and UE sends the register requirement of Call-ID2 to P-CSCF;
S606, P-CSCF is forwarded to S-CSCF with register requirement;
S607, S-CSCF judge that this User Status is a login state, and Call-ID2 and Call-ID1 are inequality, but belong to same multi-registration group, carry out the multi-registration flow process;
S608, S-CSCF return the response of succeeding in registration and give P-CSCF;
S609, P-CSCF return the response of succeeding in registration and give UE, have finished this register flow path thus, are called registration two in this example;
This moment, UE had two registrations simultaneously simultaneously in the IMS network, the From of two registrations, To header field content are identical, but two registrations can be used Call-ID separately, promptly, Call-ID1 and Call-ID2 distinguish, and can related be called a multi-registration group of multi-registration each other by Call-ID simultaneously.The described situation when being used for two registrations simultaneously of Fig. 6 when the needs registration surpasses two multi-registration, then repeats S605～S609 flow process and gets final product.
Situation when Fig. 6 represents to be employing Call-ID association, when adopting Instance-ID related, principle and Fig. 6 are similar, change Call-ID into Instance-ID and get final product in Fig. 6 example.
If when adopting access way information, registration one is carried different access way information with registration two, will carry out many registrations.
Example 3, non-many registration scenarios.
Fig. 7 is the signaling process figure according to example 3 non-many registrations of the embodiment of the invention.As shown in Figure 7, concrete steps comprise:
S701, not in the IMS registration, UE generates Call-ID1 to current UE as yet, and its flow process is identical with S501, and UE sends the register requirement of carrying Call-ID1 and arrives P-CSCF;
S702, P-CSCF is forwarded to S-CSCF with register requirement;
S703, S-CSCF receives after this register requirement, judge that this user is the state of having not yet registered, and handle this register requirement, after finishing registration, return the response of succeeding in registration to P-CSCF, and comprise Call-ID1 word string content at interior log-on message in the S-CSCF preservation, this User Status also becomes login state;
S704, P-CSCF will succeed in registration to respond and return to UE, finish the registration of UE at the IMS network thus, and this example is called registration one with this registration;
S705, UE generated the Call-ID2 that does not belong to same multi-registration group with registration one before initiating second register requirement, its product process is seen S501, and UE sends the register requirement of Call-ID2 to P-CSCF;
S706, P-CSCF is forwarded to S-CSCF with register requirement;
S707, S-CSCF judge that this User Status is a login state, and Call-ID2 and Call-ID1 are inequality, and do not belong to same multi-registration group, carry out the normal registration flow process;
S708, S-CSCF return the response of succeeding in registration and give P-CSCF;
S709, P-CSCF return the response of succeeding in registration and give UE, have finished this register flow path thus, are called registration two in this example;
S710, S-CSCF are after the S707 that finishes dealing with, and network-initiated deregistration registers one, and a shared Session Resources is registered in release.
If when adopting Instance-ID to do sign, registration one during with the Instance-ID that registers two judgment principle all identical with flow process.If when adopting access way information as sign, registration one and registration two after registration two is succeeded in registration, will be nullified registration one when inserting under the same access way, and discharge and register a shared Session Resources.
Example 4, the situation that many registrations refresh.
After UE has finished many registrations shown in Figure 6, also need to safeguard a plurality of registrations of succeeding in registration, wherein the periodic refreshing registration is essential, and Fig. 8 registers the signaling process figure that refreshes according to the example more than 4 of the embodiment of the invention, and its step is as follows:
S801, in the very first time, UE judges needs refresh registration one this moment, initiates the registration refresh requests to P-CSCF, and the Call-ID in the request adopts and adopts Call-ID1 when registering;
S802, P-CSCF transmit the registration refresh requests to S-CSCF;
S803, S-CSCF finds this user's registration one according to Call-ID1 in the registration refresh requests, then according to the information of refresh requests refresh registration one;
S804, behind the Flushing success, S-CSCF returns the response of succeeding in registration to P-CSCF;
S805, P-CSCF returns the response of succeeding in registration to UE, and refreshing smoothly of registration one finished;
S806, in second time, UE judges needs refresh registration two this moment, initiates the registration refresh requests to P-CSCF, the Call-ID2 that the Call-ID in the request adopts when adopting registration two registrations;
S807, P-CSCF transmit the registration refresh requests to S-CSCF;
S808, S-CSCF finds this user's registration two according to Call-ID2 in the registration refresh requests, then according to the information of refresh requests refresh registration two;
S809, behind the Flushing success, S-CSCF returns the response of succeeding in registration to P-CSCF;
S810, P-CSCF returns the response of succeeding in registration to UE, and refreshing smoothly of registration two finished.
If when adopting the Instance-ID sign, registration one is identical with the Instance-ID of registration two, when perhaps adopting the access way message identification, registration one is identical with the access way of registration two, then register two succeed in registration after, will nullify registration one, and discharge the shared Session Resources of registration one.As seen, make many registration refresh technique, the registration that can finish the user smoothly refreshes.
In sum, by means of technical scheme of the present invention, can realize many registrations easily, thereby make things convenient for combining various network services.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
