Description

A kind of method and system of definite paging transmission channel
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and system of definite paging transmission channel.
Background technology
In the prior art, the travelling carriage that is under URA_PCH (UTRAN Registration Area Paging Channel, the UTRAN Acceditation Area paging channel) state can not directly carry out data transmission and reception.When network side has data or calling will be handed down to the travelling carriage of URA_PCH state, need be at the PCH of network side (Paging Channel, paging channel) sends beep-page message and notify travelling carriage, after travelling carriage was received beep-page message, state transition entered into other states and carries out data transmission and reception.For purpose of saving, the travelling carriage that is under the URA_PCH state is carried out discontinuous reception (Discontinuous Reception, DRX), travelling carriage is according to the discontinuous receiving cycle and the algorithm that consult with network side, calculate and when should go to receive one's own beep-page message, concrete grammar is as follows:
Each paging channel (PCH) all has a Page Indication Channel (Page Indicator Channel, PICH) pairing is used with it, travelling carriage only goes PI (Paging Indication, paging indication) information on the discontinuous monitoring PICH in certain paging occasion (paging occasion).The calculating of paging occasion:
Paging?Occasion＝{(IMSI?div?K)mod(DRX?cycle?length?div?PBP)}*PBP+n*DRX?cycle?length+Frame?Offset； (1)
PI＝DRX?Index?mod?Np；
where?DRX?Index＝IMSI?div?8192
Wherein: IMSI (Intemational Mobile Subscriber Identity IMSI International Mobile Subscriber Identity) is used to identify international mobile subscriber; K is the number of the SCCPCH (Secondary CommonControl Physical Channel, Secondary Common Control Physical Channel) of available carrying PCH; DRX cycle length is discontinuous receiving cycle; PBP is a paging block periodicity, for FDD (Frequency Division Duplex, frequency division multiplexing), PBP=1; Frame Offset is vertical shift, and for FDD, vertical shift is 0, and for TDD (Time Division Duplex, time division multiplexing), frame offset value is specified in system message; N PICHBe the frame number of bearing call indication frame, equal the repeat length of calling indicating frame; N GAPIt is the frame number between the frame of the frame of last bearing call indication of certain paging occasion and first bearing call message; DRXIndex is discontinuous reception index, and its value is (IMSI div 8192); For FDD, Np is the number of a paging indication in the frame, and for TDD, Np is the number of a paging indication in the paging block; N PCHNumber for paging group.Wherein, N PICH, N p, N PCHAll in system message, issue.
By above formula, travelling carriage can calculate the SFN (System Frame Number, System Frame Number) of the calling indicating frame that oneself needs monitoring and the PI that needs monitoring.If the information that monitors one's own paging indication in paging occasion is " follow-up have beep-page message ",, specifying t for FDD PICHBehind=the 7680chips, to the last paging receiving message (PCH is a transmission channel, and it is mapped to physical channel is SCCPCH) of the SCCPCH of bearing call message.The time slot of PICH and SCCPCH relation as shown in Figure 1 among the prior art WCDMA.
PICH frame structure in WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) comprises 288 bits that are used for paging indication and 12 bits of reservation as shown in Figure 2.In the Release7 version of WCDMA, introduced enhancing paging characteristic, for the Cell_PCH state that support to strengthen the paging characteristic down or the travelling carriage under the URA_PCH state, can utilize HSDPA (High SpeedDownlink Package Access, the high-speed downlink packet access) technology realizes the increase of transmission bit rate, promptly from HS-PDSCH (High-Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel (HS-PDSCH)) paging receiving message, the time slot relation of PICH and HS-PDSCH as shown in Figure 3.Its concrete implementation is as follows:
For the travelling carriage under the URA_PCH state, if the travelling carriage support strengthens the paging characteristic, and when travelling carriage entered into the sub-district of a support enhancing paging characteristic, travelling carriage can be indicated according to the paging that existing mode is monitored on the Page Indication Channel.Be with the difference of non-enhancing paging, strengthening the K that paging is used for calculating the formula of paging occasion is the number of supporting the PICH of HSDPA from system broadcast message in the sub-district that obtains, and the channel of the PICH of mobile station supervision is to calculate and select by the U-RNTI of relevant information in the reading system broadcast and travelling carriage (User Radio Network Temporary Identity, user radio network temporary mark):
The numbering of the Page Indication Channel of the selected monitoring of travelling carriage=U-RNTI mod K
K value in the formula is the bar number of candidate's Page Indication Channel of support HSDPA.
The information of monitoring Page Indication Channel and detecting one's own paging indication when the travelling carriage of URA_PCH state is " follow-up have beep-page message ", then after designated time intervals, HS-PDSCH (High-Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel (HS-PDSCH)) to the bearing call message content goes up the paging receiving message content.
A kind of communication system comprises as shown in Figure 4 in the prior art:
SRNC (Serving RNC, Serving RNC) is meant RRC (Radio Resource Control between travelling carriage and the network, unlimited resources control) destination node of agreement, the RRC context of travelling carriage all is stored in the Serving RNC, and SRNC is unique interface that travelling carriage and core net communicate.
CRNC (Controlling RNC, control RNC) is meant that travelling carriage owing to reason such as moving, has entered in the sub-district that belongs to this RNC, and travelling carriage has used the resource in this RNC scope, but travelling carriage and core net still need to pass through SRNC when communicating.
The Serving RNC of travelling carriage and control RNC may be same RNC, also can be different RNC.When the Serving RNC of travelling carriage is inconsistent with control RNC, Serving RNC can determine to initiate the process (being the service radio network system repositioning process) of SRNSRelocation, the RRC context of travelling carriage is transferred to control RNC from Serving RNC, thereby the control RNC before making becomes its Serving RNC.
Scene below considering: in the communication system shown in Figure 4, travelling carriage is in the URA_PCH state.Set up RRC in the sub-district of travelling carriage in radio network controller A scope and connect, promptly radio network controller A is the Serving RNC of travelling carriage.But afterwards owing to reasons such as moving of travelling carriage, travelling carriage has resided among the sub-district D under the radio network controller B, and promptly radio network controller B becomes the control RNC of travelling carriage.
Sub-district E among Fig. 4 in the radio network controller C scope belongs to identical URA with the sub-district D under the radio network controller C, also promptly when travelling carriage owing to reason such as moving and carry out the sub-district gravity treatment from sub-district D gravity treatment to sub-district E, though current wireless network controller C becomes the control RNC of travelling carriage, travelling carriage can't be initiated URA renewal process informing network side.
When Serving RNC is received from the data of the state of the URA_PCH hereto travelling carriage of core net or is called out, owing to can store the RRC context of this travelling carriage in the Serving RNC, therefore can know the RRC state of this travelling carriage and the URA identification information at place, so in belonging to the sub-district of this URA, send beep-page message, the specific implementation process may further comprise the steps as shown in Figure 5:
Step s501, Serving RNC sends paging request message to other the RNC that comprises this URA sub-district at least, carry in this paging request message: paging area (paging territory), promptly the URA identification information, exhaled the IMSI of travelling carriage, and the information such as DRX cycle parameter of this travelling carriage.Wherein, the paging territory is meant the scope that needs to send paging, can be a URA sign, also can be the sign of a sub-district, when control RNC obtains the paging territory, has promptly known to send this beep-page message in the scope of which sub-district.
Step s502, the RNC that receives paging request message is (in the communication system of Fig. 4, RNC B and RNCC can receive this paging request message), according to the paging occasion of IMSI that is exhaled travelling carriage and DRX cycle calculation of parameter travelling carriage, and the information of the content of beep-page message and PI indication is placed in the PCH Frame sends to the base station by Iub interface.
Step s503, the PCH Frame is received in the base station, then according to the content in the PCH Frame, sends paging indication information in the relevant position of Page Indication Channel, sends the content of beep-page message at the SCCPCH channel.
Step s504, travelling carriage are according to the IMSI of oneself, and information calculations such as DRX parameter go out to monitor the opportunity of paging indication, and judge whether that according to the information of paging indication needs are to SCCPCH channel paging receiving message content.
After introduce strengthening the paging characteristic, among the above-mentioned step s502, the RNC that receives the paging request also may be placed on the information of the content of beep-page message and PI indication in the HS-DSCH Frame and send to the base station by Iub interface.
Step s503, the HS-DSCH Frame is received in the base station, then according to the content in the HS-DSCH Frame, sends paging indication information in the relevant position of Page Indication Channel, sends the content of beep-page message at the HS-PDSCH channel.
The cell capacity information decision of expressing in the ability information of travelling carriage basis oneself and the system broadcast message of current area still is a paging receiving message on the HS-PDSCH channel in paging receiving message on the SCCPCH channel.
In sum, in realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: according to the description of existing protocol, if the travelling carriage support strengthens the function of paging, and the relevant information in the system broadcast message show travelling carriage current resident sub-district also be when support strengthening paging function, travelling carriage is in the paging indication that listens on the Page Indication Channel, the content that next can remove to answer on the HS-PDSCH channel beep-page message.Yet the system broadcast message in the persistent district that travelling carriage receives is the configuration that comes from CRNC, i.e. current area support strengthens paging can only show that CRNC supports to strengthen the paging characteristic, can not show whether SRNC supports to strengthen the paging characteristic.
Though CRNC can carry the ability information whether the information acquisition travelling carriage supports to strengthen paging from travelling carriage cell update or URA updating message, judge according to the ability information of travelling carriage then beep-page message is sent in SCCPCH channel or HS-PDSCH channel.Yet, when if travelling carriage was never initiated up access in the scope of current C RNC, be that the gravity treatment of travelling carriage sub-district is to different RNS (Radio Network Subsystem, RNS) scope, but the process that URA upgrades need not be initiated in the sub-district that still belongs to identical URA therefore.Therefore whether CRNC is iff supporting the ability information that strengthens paging to select paging channel according to this sub-district, and travelling carriage may can not receive beep-page message, has the possibility of call loss.
Such as in Fig. 4, when the scope of travelling carriage from sub-district D gravity treatment to sub-district E, because sub-district D belongs to identical URA with sub-district E, therefore when network side need be to the Mobile Origination paging, travelling carriage was not also initiated up signaling and was inserted in the scope of radio network controller C, so radio network controller C can't learn the ability information of travelling carriage, also just can't know after travelling carriage is received the paging indication and can go SCCPCH to monitor beep-page message on the HS-PDSCH channel, so there is the possibility of call loss.
Summary of the invention
The embodiment of the invention provides a kind of method and system of definite paging transmission channel, to solve the ability information that to learn travelling carriage in the prior art, after can't learning that also travelling carriage is received the paging indication, can remove SCCPCH still is the problem of monitoring beep-page message on the HS-PDSCH channel.
For achieving the above object, the embodiment of the invention provides a kind of method of definite paging transmission channel on the one hand, may further comprise the steps:

Embodiment
Control RNC obtains the ability information of travelling carriage and the ability information in paging territory in the embodiment of the invention, controls RNC then according to the ability information of described travelling carriage and the definite channel that sends beep-page message of ability information in paging territory.Wherein, the ability information of described travelling carriage is whether described travelling carriage supports to strengthen the paging characteristic, and the ability information in described paging territory is whether described beep-page message transmission sub-district supports to strengthen the paging characteristic.
Wherein, determine that according to the ability information in the ability information of travelling carriage and paging territory the channel that sends beep-page message specifically comprises: when control RNC receives service wireless network controller SRNC for the paging request of certain travelling carriage, determine and described paging request need be handed down to described travelling carriage in a sub-district of supporting to strengthen the paging characteristic; Described control RNC judges whether to store the information that described travelling carriage support strengthens paging, if having, then sends beep-page message on HS-PDSCH, indicates described travelling carriage to send beep-page message according to strengthening the paging mode on HS-PDSCH.If do not store the information that described travelling carriage support strengthens paging among the described control RNC, then described control RNC strengthens described travelling carriage the paging characteristic and supports two kinds of situations that strengthen the paging characteristic to calculate two paging occasion according to not supporting, and all transmits corresponding paging indication in described two paging occasion.
Wherein, judge that the information that stores described travelling carriage support enhancing paging comprises before: described control RNC obtains and stores described travelling carriage and whether supports to strengthen the paging characteristic.Described control RNC obtains and stores described travelling carriage and whether supports to strengthen the paging characteristic and specifically comprise: described travelling carriage sends update request to described SRNC, comprises in the described request whether described travelling carriage supports to strengthen the indication of paging characteristic; Described SRNC sends the paging request to described control RNC, carries described indication in the described request; Described control RNC obtains and stores described indication.Or described control RNC receives the RRC message that sends when described travelling carriage upgrades, and obtains and store the indication whether travelling carriage described in the described message supports to strengthen the paging characteristic.Or, initiate up access in travelling carriage certain sub-district in URA and carry the ability information of supporting to strengthen the paging characteristic; By the information interaction between the RNC, the ability information of travelling carriage is obtained by all control RNC that have at least a sub-district to belong to this URA scope.
A kind of travelling carriage is determined the paging transmission channel method in the embodiment of the invention one, as shown in Figure 6, may further comprise the steps:
Step s601, travelling carriage carry the information that the travelling carriage support strengthens the paging performance capabilities in sending to the uplink RRC (Radio Resource Control) signaling of network side;
This uplink RRC (Radio Resource Control) signaling is including but not limited to following RRC signaling: can be that RRC connects the RRC signaling of setting up in the process, can be cell update message, can be the URA updating message.
Step s602, Serving RNC strengthens the information stores of paging performance capabilities in the RRC of this travelling carriage correspondence context with this travelling carriage support;
Step s603, control RNC paging receiving request message;
Carry travelling carriage in this paging request message and whether support to strengthen the indication information of paging characteristic;
Perhaps also can only carry the indication information that the travelling carriage support strengthens the paging characteristic, think when not carrying this information that travelling carriage do not support to strengthen the paging characteristic.
Step s604, control RNC send the channel of beep-page message according to the ability information decision in the ability information of travelling carriage and paging territory.
If the travelling carriage support strengthens paging, and the sub-district support enhancing paging characteristic of beep-page message transmission, then on the HS-PDSCH channel, send beep-page message;
If the travelling carriage support strengthens paging, but the paging characteristic is not supported to strengthen in the sub-district that beep-page message sends, and then sends beep-page message on the SCCPCH channel;
If travelling carriage does not support to strengthen paging, but enhancing paging characteristic is supported in the sub-district that beep-page message sends, and then sends beep-page message on the SCCPCH channel;
If travelling carriage does not support to strengthen paging, and the sub-district that beep-page message sends do not support to strengthen the paging characteristic, then sends beep-page message on the SCCPCH channel.
That is, have only when the sub-district of travelling carriage and beep-page message transmission is supported to strengthen the paging characteristic simultaneously, just on the HS-PDSCH channel, send beep-page message.
A kind of travelling carriage is determined the paging transmission channel method in the embodiment of the invention two, as shown in Figure 7, may further comprise the steps:
Step s701, travelling carriage carry the information that the travelling carriage support strengthens the paging performance capabilities in sending to the uplink RRC (Radio Resource Control) signaling of network side;
This uplink RRC (Radio Resource Control) signaling is including but not limited to following RRC signaling: can be that RRC connects the RRC that sets up in the process and connects and set up demand signalling, can be that RRC connects to set up and finishes, and can be cell update message, can be the URA updating message.
Step s702, RNC is from the described up RRC message of step s701 in control, and whether acquisition and storing mobile station support to strengthen the information of paging characteristic.
Step s703, control RNC paging receiving request message.
Step s704, s604 is identical with step.
The something in common of embodiment one and embodiment two is that control RNC need obtain the ability information whether travelling carriage supports to strengthen the paging characteristic by certain approach; And utilize the ability information of travelling carriage and need the sub-district of issuing page message whether to support the ability information that strengthens the paging characteristic to judge issuing page message on which channel jointly.Different is, among the embodiment one is to obtain from the paging request message that Serving RNC sends, and is to obtain from travelling carriage sends to the up RRC message of network side among the embodiment two.
A kind of travelling carriage is determined the paging transmission channel method in the embodiment of the invention three, as shown in Figure 8, may further comprise the steps:
When step s801, Serving RNC distributed new U-RNTI for travelling carriage at every turn, when perhaps each Serving RNC sign changed, network side carried the indication whether SRNC supports to strengthen the paging characteristic in the RRC message that travelling carriage sends.Wherein, described RRC message can include but not limited to following message: switch to UTRAN order (HANDOVER TO UTRAN COMMAND); Physical channel reconfiguration message (PHYSICAL CHANNEL RECONFIGURATION); Radio bearer configuration messages (RADIO BEARER RECONFIGURATION); Radio bearer release message (RADIOBEARER RELEASE); Radio bearer is set up message (RADIO BEARER SETUP); Message (RRC CONNECTION SETUP) is set up in the RRC connection; Transmission channel reconfiguration message (TRANSPORT CHANNEL RECONFIGURATION); URA upgrades acknowledge message (URAUPDATE CONFIRM); UTRAN moving notification message (UTRAN MOBILITYINFORMATION).
Step s802, travelling carriage can judge whether Serving RNC supports to strengthen paging by this indication;
When network side is that travelling carriage has distributed new U-RNTI, but when but not carrying this indication, travelling carriage can think that this Serving RNC do not support to strengthen the paging characteristic.
Step s803, control RNC receives paging request message.
Step s804, control RNC sends beep-page message according to the ability information decision paging channel of travelling carriage;
Whether do not support to strengthen the information of paging about this travelling carriage if there is storage among the control RNC, then control RNC travelling carriage hereto, on the relevant Page Indication Channel of the relevant Page Indication Channel of its HS-PDSCH channel and SCCPCH, all send paging indication information.
Promptly control RNC when calculating paging occasion and PI bitmap (bitmap), to be exhaled travelling carriage according to two kinds of situations not supporting to strengthen the paging characteristic and support to strengthen the paging characteristic, calculate two paging occasion, promptly the SFN of two PICH number, and in these two paging occasion, all transmit corresponding paging indication, show " follow-up have beep-page message " to travelling carriage, and in the extended bit of the relevant Page Indication Channel frame of HS-PDSCH channel, comprise the information of " beep-page message is at SCCPCH ".
Step s805, the content of transmission beep-page message on the SCCPCH channel.
Step s806, if the travelling carriage support strengthens the paging characteristic, then travelling carriage can be read the paging indication on the relevant Page Indication Channel of HS-PDSCH channel and the information of " beep-page message is at SCCPCH " in the extended bit.Thereby the content of paging receiving message to the SCCPCH channel next.
Among the embodiment three, the travelling carriage that only meets the following conditions can remove to read the extended bit in the PICH frame: travelling carriage is in the URA_PCH state, the travelling carriage support strengthens the paging characteristic, and the paging characteristic is supported to strengthen in current sub-district of living in, and it (may be because SRNC is the RNC of version before the Rel 7 that the Serving RNC of travelling carriage does not support to strengthen the paging characteristic, or Rel 7 versions RNC who does not still support to strengthen the paging characteristic afterwards), even the discontented travelling carriage that is enough to condition is read this extended bit, also can ignore its implication.
Can know that from above analysis the paging of not satisfying these conditions still can utilize the HSDPA channel to issue; Even satisfy these conditions, beep-page message still has an opportunity to issue at the HSDPA channel, and this depends on whether control RNC understands the enhancing paging performance capabilities of travelling carriage, so can effectively utilize the HSDPA characteristic.
In the embodiment of the invention four, the travelling carriage that the support that is in the URA_PCH state strengthens the paging characteristic recognizes that Serving RNC do not support to strengthen the paging characteristic, and the current area support strengthens the paging characteristic, and then travelling carriage is in SCCPCH channel paging receiving message.Control RNC will be exhaled travelling carriage according to not supporting the travelling carriage that strengthens the paging characteristic to handle when calculating paging occasion and PI bitmap.Detailed process may further comprise the steps as shown in Figure 9:
Step s901～s903 is identical with step s801～s803.
Step s904 as control RNC when receiving the paging request, does not support to strengthen the paging characteristic if control RNC is known Serving RNC, and then travelling carriage hereto sends paging indication information on the relevant Page Indication Channel of SCCPCH.
Control RNC learns that the method that strengthens the paging characteristic of whether supporting of Serving RNC can be: control RNC can obtain from the signaling that SRNC sends, and also can obtain from the signaling that travelling carriage is sent.
Step s905, travelling carriage listen to the paging indication back paging receiving message to the SCCPCH channel on the relevant paging channel of SCCPCH.
The embodiment of the invention five may further comprise the steps as shown in figure 10:
Step s1001, control RNC paging receiving request message.
Step s1002, if control RNC need be in support strengthening the sub-district of paging issuing page message, then control RNC and need judge whether to have stored the information of whether supporting to strengthen paging about this travelling carriage, if do not have, then change step s1003.Certainly, step s1002 also can omit in the practical application.
Step s1003, issuing page message in the sub-district that control RNC indicates in the paging request.Control RNC sends beep-page message on HS-PDSCH channel and SCCPCH channel,
The mode that sends can send beep-page message simultaneously on HS-PDSCH channel and SCCPCH channel, perhaps;
Can on HS-PDSCH, send beep-page message earlier,, on SCCPCH, send beep-page message again if do not receive the page response of travelling carriage within a certain period of time; Perhaps
Can on SCCPCH, send beep-page message earlier,, on HS-PDSCH, send beep-page message again if do not receive the page response of travelling carriage within a certain period of time; Perhaps
Also can on HS-PDSCH, send the beep-page message of certain number of times earlier, on SCCPCH, send the beep-page message of certain number of times again; Perhaps
Also can on SCCPCH, send the beep-page message of certain number of times earlier, on HS-PDSCH, send the beep-page message of certain number of times again; Perhaps
Also can on HS-PDSCH and SCCPCH, send beep-page message at interval.In a word, no matter take which kind of send mode,, just belong to protection scope of the present invention so long as on two channels, all sent out.
If in not supporting to strengthen the sub-district of paging characteristic, issue, then control RNC and only on SCCPCH, transmit beep-page message.
In embodiment five, if control RNC need be in not supporting to strengthen the sub-district of paging characteristic issuing page message, then control directly issuing page message on the SCCPCH channel of RNC.If stored the ability information of being exhaled travelling carriage among the control RNC, then when the sub-district of travelling carriage and beep-page message transmission is all supported to strengthen the paging characteristic, on high-speed physical downlink shared channel (HS-PDSCH) HS-PDSCH channel, send beep-page message.When the sub-district of travelling carriage and/or needs transmission beep-page message is not supported to strengthen the paging characteristic, on the SCCPCH channel, send beep-page message.
The embodiment of the invention six as shown in figure 11, may further comprise the steps:
Step s1101～s1102 is identical with S601～S602.
Step s1103, the URA identification information that Serving RNC can belong to according to travelling carriage, the enhancing paging performance capabilities information of travelling carriage is notified to other RNC that have at least a sub-district to belong to this URA, strengthens the ability information of paging characteristic so the control RNC at travelling carriage place can know the travelling carriage support.
Step s1104, control RNC paging receiving request message.
