Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The present invention in view of the prior art in after UTRAN (Universal Mobile Communication System land radio access web) side call drop again
Secondary the problem of exhaling unsuccessfully, provides a kind of method that link is removed between radio network controller and core net, as shown in Figure 1, packet
It includes:
Step 11: receiving the Iu Connection Release that cause value is a self-defining value that carries that core net issues and instruct；
Step 12: the Iu connection removed between core net is instructed according to the Iu Connection Release.
Self-defining value described in the embodiment of the present invention is preferentially selected as remove-MobileID (removal-movement ID).
The method of link is removed between the radio network controller provided in an embodiment of the present invention and core net by connecing
The cause value that carries that core net issues is received to remove between core net for after the Iu Connection Release instruction of a self-defining value
Iu connection solves (the Universal Mobile Communication System land UTRAN so that wireless net side is consistent with the User Status of core-network side
Wireless access network) the problem of exhaling unsuccessfully is acted again after the call drop of side.
The embodiment of the present invention provides two kinds of counter-measures for practical situations, the first: receiving core net and issue
Carrying cause value the step of being the Iu Connection Release instruction of a self-defining value include: that the Radio Link that reports of receiving node B loses
The report lost；When determining that the terminal connecting with node B carries out voice service according to the report of the Radio Link Failure, to core
Online report cause value is the Iu connection release request of the self-defining value；Core net is received according under the Iu connection release request
The Iu Connection Release that cause value is the self-defining value that carries of hair instructs.
Further, the method also includes: end for connecting with node B is determined according to the report of the Radio Link Failure
When end is without carrying out voice service, Xiang Suoshu node B issues wireless link-activation instruction, so that node B deactivation is wireless
Link, and then the triggering terminal initiates cell update or the timer that goes offline overtime can be triggered and be gone offline.
Second: receiving packet the step of carrying the Iu Connection Release instruction that cause value is a self-defining value that core net issues
It includes: receiving core net and requested according to the call management service that terminal reports, determined the Iu connection of Mobile sign in the request
In the presence of and establish reason be the terminal carry out voice service when, issue carry cause value be the self-defining value Iu connection
It releases order.
Further, the method also includes: receive the call management service request that core net reports according to the terminal,
In the absence of the Iu connection for determining Mobile sign in the request, what is issued establishes the first instruction of call management service；Receive core
Heart net is requested according to the call management service that the terminal reports, and determines that it is that the terminal carries out language that reason is established in the request not
When sound business, what is issued establishes the second instruction of call management service.Wherein, the first instruction is identical with the second instruction, can be
It is instructed into authentication, safe mode command, the authentication etc. in call management service establishment process.
Below between the radio network controller provided in an embodiment of the present invention and core net remove link method into
Row illustrates.
Typical fault signaling as shown in Figure 2, serial number 9-10:Paging Response (page response) can be seen that this
It is an incoming call.Parse the signaling, it can be seen that the Mobile ID of carrying is as shown in Figure 3.
In Fig. 4, serial number 43-46: voice call is connected.Serial number 47:Node B (node B) detects continuous uplink loss
Time be more than some threshold values after, will trigger reporting Radio Link Failure Indication (Radio Link Failure refers to
Show) to RNC.Each producer defines triggering Radio Link Failure Indication timer different.Serial number
48:Node B reports Radio Link Failure Indication triggering RNC to issue Radio Link Activation
Command (wireless link-activation instruction) gives Node B, instruction Node B to close downlink.
Since the downlink of network side is switched off, cause end-probing less than downlink, so as to cause terminal judgement
Downlink failure, stops at the transmission of old chain road, so that UE is reselected wireless by cell update (Cell Update)
Quality more preferably cell, the cell are likely to be source cell, it is also possible to be other cells.In present case, UE is selected just
It is other cell (Cell ID=29223), as shown in Figure 5, wherein serial number 97-98:UE is in new cell (Cell ID=
29223) voice call service is initiated, sends CM Service Request, cause value is Original Conversational
Call (original talk calling), the Mobile ID (92232494) of carrying is as in Paging Response above.Sequence
Number 101-102: core net refuses the CM Service Request.The reason of CM Service Reject, is: Message
Not compatible with the protocol state, as shown in Figure 6.
Concrete reason analysis: after uplink loss, the timer (actually call drop timer) of RNC release call is existing
It is 15.25 seconds under net configuration.It is different for the calculation of the different producers call drop timer.Nevertheless, all
It is set larger than 0, having from 7,8 seconds to more than ten seconds.
RNC indicates that Node B stops after downlink (Radio Link Activation Command), and the call of UE is real
Border has stopped, time point 10:00:12:821 (serial number: 48).
UE cell update is initiated CM Service Request (CS audio call) again to other cells, time point 10:
00:19:371 (serial number: 97).
It is separated by about 7 seconds (between call drop and again initiation CS audio call) between two time points, far smaller than RNC is released
Put talk timer 15.25 seconds.Before timer expiry, RNC be will not initiate Iu Release Request (Iu release asks
Ask), therefore the Iu connection between RNC and CN still maintains.After core net receives CM Service Request, core net hair
The reason of its existing Mobile ID carried probably already exists Iu connection, will refuse the secondary CM Service Request, refusal be
Message not compatible with the protocol state, to cause the access failure of CS voice call.
The embodiment of the present invention provides a kind of new algorithm flow on the basis of 3GPP protocol specification, goes to avoid such event
The generation of barrier, the voice for promoting client connect perception.
Firstly, the Cause (cause value) of customized one new Iu Release Request.According to 3GPPTS25.413
The reason of middle 9.2.1.4 (Radio Access Network Application Part Protocol) standardizes, Iu Release Request value is divided into standard (standard) and non-
Two kinds of standard (non-standard), wherein serial number 1-128,257-512 is standard, and serial number 129-256 is non-
Standard can leave main equipment producer oneself definition for.
The embodiment of the present invention selects wherein 1 serial number (protocol specification serial number 256 is obsolete) in 129-256, newly
Increase a Cause value, is defined as: remove-MobileID (self-defining value in the embodiment of the present invention) is then carrying
Cause value provides corresponding signaling process for the Iu Release Request of remove-MobileID.
According to existing procedure, after RNC reports Iu Release Request to CN, first Iu can be issued by triggering CN
Release Command completes taking out stitches for Iu connection between RNC and CN；Then RNC issues RRC Connection Release
(RRC Connection Release) is completed RRC connection and is removed between UE and RNC；Last RNC issues Radio Link Deletion
Request (Radio Link removes request), instruction NodeB complete the dismounting of physical link, as shown in Figure 7.
Signaling process provided in an embodiment of the present invention is, if RNC, which is reported, carries cause value as remove-MobileID's
The reason of carrying in Iu Release Request, the Iu Release Command that CN is issued also is remove-MobileID.
After RNC receives the Iu Release Command that the reason of CN is issued value is remove-MobileID, RNC connects without RRC
The relevant operation removed with physical link is connect, the dismounting of Iu connection is only completed between RNC and CN.
The embodiment of the present invention provides two kinds of specific algorithms for the definition of two above signaling and process, the first, such as
Shown in Fig. 8:
After step 81:RNC receives the Radio Link Failure that Node B is reported, judge whether UE carries out CS voice industry
Business.If being, 82 are entered step；If no, 85 are entered step.
It is the Iu Release Request of remove-MobileID that step 82:RNC, which reports cause value to CN,.
Step 83:CN issues the Iu Release Command for carrying that cause value is remove-MobileID to RNC.
It carries out Iu connection between step 84:RNC and CN to remove, but the phase that RNC is removed without RRC connection and physical link
Operation is closed, it then,, will not be by CN even if UE re-initiates CM Service Request before call drop timer expiry
Refusal.
Step 85:RNC issues Radio Link Activation Command to Node B.
Step 86:Node B deactivates nothing after receiving the Radio Link Activation Command that RNC is issued
Wired link, triggering UE initiate cell update process or call drop (line) timer expiry triggering call drop (line).
Second, as shown in Figure 9:
Step 91:CN receives the CM Service Request that UE is reported, parse Mobile ID therein and
(CM Service Request is that UE issues CN to Establishment Cause, and RNC is passed through in centre, but RNC is intermediate
A transparent transmission is done, without any processing).
Step 92:CN judges whether the Iu connection of the Mobile ID has existed.If being, 93 are entered step；It is no
If, enter step 96.
Step 93:CN judges whether it is CS voice call from Establishment Cause.If being, 94 are entered step；
If no, 96 are entered step.
Step 94:CN issues the Iu Release Command that cause value is remove-MobileID to RNC.
It carries out Iu connection between step 95:RNC and CN to remove, but the phase that RNC is removed without RRC connection and physical link
Close operation.
Step 96: carrying out normal CM Service (call management service/CS audio call) Establishing process.
To sum up, the embodiment of the present invention defines one and carries the Iu Release that cause value is remove-MobileID
Request message, and corresponding signaling process is provided for it: if RNC reports carrying, cause value is remove-MobileID's
The reason of carrying in Iu Release Request, the Iu Release Commmand that CN is issued also is remove-
MobileID.When RNC receive the reason of CN is issued value be remove-MobileID Iu Release Command after, RNC and
The dismounting of Iu connection, but the relevant operation that RNC is removed without RRC connection and physical link are completed between CN, are successfully solved
It is risen again after the side UTRAN call drop and exhales unsuccessfully failure, innovative value with higher and practical value, and the embodiment of the present invention mentions
