Abstract
The invention provides a method that can ensure service to run normally in normal domain when location registration fails and a wireless network controller. That the cause value of refusal information of location registration is forbidding general packet radio service or international portable user identity in home location register is judged; after receiving the information of the position location result and cause value, the wireless resource control keeps staying in existing micro-plot, so as to ensure normal operation to run normally in normal domain. Therefore, the invention can make up for the shortage of protocol to ensure that when one domain registration fails, the service in another normal domain can work normally.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of LR failure back and guarantee method and the radio network controller that the business in normal territory is normally carried out.
Background technology
At present, terminal is at Location Registration (LR, Location Registration) in the process, if receiving cause value is the refuse information of " forbidding GPRS (General Packet Radio services not allowed) " and " international mobile subscriber identification code the unknown in the attaching position register (International MobjleSubscriber Identity unknown in Home Location Register) ", in 25.304 agreements, require Radio Resource control (RRC, Radio Resource Control) carries out " any cell search (ANY CELL SEARCH) ", like this under " any sub-district " state, no matter non-GPRS (non-GPRS) business or gprs service all can be in constrained state.Specify as follows:
One, terminal is the refuse information of " GPRS services not allowed " if receive cause value in the LR process, the protocol requirement according to 24.008, and as shown in Figure 1, terminal need be done as follows:
1) in 24.008 agreements, this Reason For Denial does not influence the login state (promptly not influencing the non-GPRS business) of non-GPRS; But only influence the login state of GPRS, and agreement offers some clarification on subscriber identification module (SIM, Subscriber Identity Module) invalid to gprs service, up to shutdown or pull out SIM card, so be (corresponding also just can't recover gprs service) that to recover the login state of GPRS by resident new sub-district again.
2) because cause value is not allow this travelling carriage (MS for the refuse information of " GPRS services not allowed ", Mobile Station) carrying out gprs service causes, rather than because certain sub-district or certain network can not provide roaming to cause for the gprs service of this MS, so even resident again new sub-district also can not provide gprs service for this MS.
This shows, " GPRS services not allowed " be because MS does not have the GPSR service authority to cause, thus can not recover gprs service by resident new sub-district, and this cause value does not influence the non-GPRS business.MS by mobile management the GPRS mobile management (MM GMM, Mobility Management GPRS Mobility Management) login state guarantee that each territory allows the business of initiating (no matter being regular traffic or restricted service), does not need to guarantee by the state of persistent district.
Two, terminal is the refuse information of " IMSI unknown in HLR " if receive cause value in the LR process, the protocol requirement according to 24.008, and as shown in Figure 2, terminal need be done as follows:
This Reason For Denial does not influence the login state (promptly not influencing gprs service) of GPRS; But only influence the login state of non-GPRS, and it is professional invalid up to shutdown or pull out SIM card to non-GPRS that agreement offers some clarification on SIM, so be (corresponding also just can't recover the non-GPRS business) that can not recover the login state of non-GPRS by resident new sub-district again.
As from the foregoing, " IMSI unknown in HLR " only causes the non-GPRS business limited, can not recover the non-GPRS business by resident new sub-district, and this cause value do not influence gprs service.MS by MM the login state of GMM guarantee that each territory allows the business of initiating (no matter being regular traffic or restricted service), does not need to guarantee by the state of persistent district.
In sum, according to of the processing of 25.304 agreements to LR refuse information (cause value is " GPRS services notallowed " and " IMSI unknown in HLR "), terminal will reside under the professional limited Any Cell state after the LR failure, and under this state the non-GPRS business still be gprs service all be limited, obvious in this 25.304 description and 24.008 description in 23.122 be inconsistent; From the description of top agreement also as can be known, when LR be since " IMSI unknown in HLR " or " GPRS services not allowed " when refusal, by this Cell Search is the business that can't recover to be subjected to confinement, and the business in each territory by MM the login state of GMM guarantee, irrelevant with the state of persistent district, so this Cell Search there is no need.
In addition, cause value is the refuse information of " IMSI unknown in HLR ", only is effectively professional at non-GPRS, should not influence gprs service; The reason of " GPRS services notallowed " equally should be only effective at gprs service, also should not influence the non-GPRS business.
