Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to and a kind of BroadCast MultiCast Service (BCMCSBroadcast and Multicast Service) user is carried out the method for paging.
Background technology
In the mobile cellular communication system, travelling carriage can be in one of three kinds of states of idle condition, access state and processing Dedicated Traffic Channel state according to self present working condition.When travelling carriage is in idle condition, network side can according to the HASH algorithm computation go out each travelling carriage when the idle condition resident frequency (following with travelling carriage during in idle condition resident frequency be called the HASH frequency of this travelling carriage).
At present, major part mobile cellular communication system can support to provide BCMCS stream for the user, generally speaking, it is that each travelling carriage sends BCMCS stream (a general carrier frequency can carry 15 class BCMCS stream) that system concentrates on some carrier frequency of sub-district, all travelling carriages all can only by self the HASH frequency be tuned to system send and could to receive BCMCS on the carrier frequency of BCMCS stream and flow, in this case, travelling carriage just can not carry out the beep-page message of interception system side transmission on the HASH frequency of self.Therefore for the travelling carriage that receives BCMCS stream, system safeguards paging collection (the employed frequency collection when paging collection is system's mobile paging station for it, residing system sends the carrier frequency of BCMCS stream when comprising travelling carriage present located HASH frequency and receiving BCMCS stream) just seem particularly important, in order to travelling carriage no matter when idle condition is on the HASH frequency, still when receiving BCMCS stream and be on the carrier frequency that system sends BCMCS stream, can both guarantee system calling to travelling carriage, improve call completion ratio.
In the prior art, be by Access Network (AN, Access Network) the paging collection that each accesses terminal (AT, Access Terminal) to be safeguarded, later on the process of carrying out paging by each AT of this paging set pair mainly contains three kinds of schemes.
First kind of scheme: regulation AT can notify AN that self paging collection is safeguarded by routing update (RU, Route Update) message, when AN carries out paging to certain AT, need send beep-page message simultaneously on following frequency:
1) AN must send beep-page message on the HASH of this AT frequency; And
2) send beep-page message on the indicated frequency collection of the RU message that reports of this AT the last time.
Second kind of scheme: stipulated that AT can reside on self the HASH frequency and the forward direction of the BCMCS of its registration stream sends on the carrier frequency, so AN only carries out the paging collection to this two classes frequency of AT and safeguards; When AN carries out paging to certain AT, need on following frequency, send beep-page message simultaneously:
1) AN must send beep-page message on the HASH of this AT frequency; And
2) send beep-page message on the transmission carrier frequency that the BCMCS that this AT is registered flows; Wherein AN may not be included in the indicated frequency of RU message that this AT the last time reports to the transmission carrier frequency of the BCMCS stream of this AT registration and concentrates.
The third scheme: stipulated the BCMCS situation that AN needs simultaneously the RU message that reports according to AT and AT to be registered, the paging collection of AT is safeguarded, when AN carries out paging to certain AT, need on following frequency, send beep-page message simultaneously:
1) AN must send beep-page message on the HASH of this AT frequency; And
2) send beep-page message on the indicated frequency collection of the RU message that reports of this AT the last time; And
3) send beep-page message on the transmission carrier frequency that the BCMCS that this AT is registered flows; In like manner, wherein AN may not be included in the indicated frequency of RU message that this AT the last time reports to the transmission carrier frequency of the BCMCS stream of this AT registration and concentrates.
Just because of above-mentioned reason: as AT during at the relevant BCMCS of AN side registration, AN may not be included in the indicated frequency of RU message that this AT the last time reports to the transmission carrier frequency of the BCMCS stream of this AT registration and concentrate, therefore just need AN that the transmission carrier frequency of the BCMCS stream of AT registration is safeguarded, so that when paging AT, can guarantee that it also can pagedly arrive when AN sends on the carrier frequency of BCMCS stream of its application.
But in the prior art, come the transmission carrier frequency of the BCMCS stream of AT registration safeguarded by AN and may have following deficiency:
A. because as AT during to the present non-existent BCMCS of one of AN side registration, then AN does not still know to distribute which carrier frequency for the BCMCS of this registration when the BCMCS registration message of this AT of processing; Have only after AN communicates news with other network nodes, AN could determine the BCMCS stream of AT registration should send on which carrier frequency, the registration message that receives AT at AN determines that to AN the BCMCS stream of AT registration should be during sending on which carrier frequency, AN has only this registration message of first buffer memory, sets up successfully up to the bearer path of the BCMCS of AT registration and just handles; This shows that when being come the transmission carrier frequency of the BCMCS stream of AT registration safeguarded by AN, its implementation procedure is comparatively complicated.
B. simultaneously because AT sends the BCMCS registration message in the cycle, promptly send the BCMCS registration message each time to the AN side, AN will judge that its registration BCMCS stream determines its transmission carrier frequency.
C. initiatively do not carry out BCMCS when registration to AN as AT, AN just can't realize the transmission carrier frequency of the BCMCS stream of this AT registration is safeguarded, also just can't be informed in the paging AT whether on the carrier frequency that AN forward direction transmission BCMCS flows, and can cause and Lou exhale phenomenon.
