Description

A kind of method of connection management and device
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 prior art, the travelling carriage under URA_PCH (UTRAN Registration Area Paging Channel, UTRAN Acceditation Area paging channel) state can not directly carry out data input and data output.In the time that network side has data or calling will be handed down to the travelling carriage of URA_PCH state, need to be at the PCH of network side (Paging Channel, paging channel) send beep-page message notify travelling carriage, travelling carriage receives after beep-page message, and state transition enters into other states and carries out data input and data output.For economize on electricity object, travelling carriage under 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) has a Page Indication Channel (Page Indicator Channel, PICH) pairing is used with it, travelling carriage only goes PI (Paging Indication, the paging instruction) information on 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 div8192
Wherein: IMSI (International Mobile Subscriber Identity IMSI International Mobile Subscriber Identity) is for identifying international mobile subscriber; K is the number of the SCCPCH (Secondary Common Control Physical Channel, Secondary Common Control Physical Channel) of available carrying PCH; DRX cycle length is discontinuous receiving cycle; PBP is 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 pICHfor the frame number of bearing call instruction frame, equal the repeat length of calling indicating frame; N gAPit is the frame number between frame and the frame of first bearing call message of last bearing call instruction of certain paging occasion; DRXIndex is discontinuous reception index, and its value is (IMSI div8192); For FDD, Np is the number of a paging instruction in frame, and for TDD, Np is the number of a paging instruction in paging block; N pCHfor the number of 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 need the PI of monitoring.If the information that monitors one's own paging instruction in paging occasion is " follow-up have beep-page message ", for FDD, specifying t pICHafter=7680chips, to the upper paging receiving message (PCH is transmission channel, and it is mapped to physical channel is SCCPCH) of SCCPCH of bearing call message.In prior art WCDMA, the time slot relation of PICH and SCCPCH as shown in Figure 1.
PICH frame structure in WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) as shown in Figure 2, comprises 288 bits and 12 reserved bits for paging instruction.In the Release7 version of WCDMA, introduce enhancing paging characteristic, for the travelling carriage under the Cell_PCH state of support enhancing paging characteristic or under URA_PCH state, can utilize HSDPA (High Speed Downlink Package Access, high-speed downlink packet access) technology realizes the increase of transmission bit rate, 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 is as shown in Figure 3.Its concrete implementation is as follows:
For the travelling carriage under URA_PCH state, if travelling carriage support strengthens paging characteristic, and in the time that travelling carriage enters into a community of supporting to strengthen paging characteristic, travelling carriage can be monitored the paging instruction on Page Indication Channel according to existing mode.Be with the difference of non-enhancing paging, the K that enhancing paging is used for the formula that calculates paging occasion is the number of supporting the PICH of HSDPA from system broadcast message in the community obtaining, and the channel of the PICH of mobile station supervision is calculated and selected by the U-RNTI of the relevant information in reading system broadcast and travelling carriage (User Radio Network Temporary Identity, user radio network temporary mark):
Numbering=U-RNTI mod K of the Page Indication Channel of the selected monitoring of travelling carriage
K value in formula is the number of candidate's Page Indication Channel of support HSDPA.
The information of monitoring Page Indication Channel and one's own paging instruction being detected when the travelling carriage of URA_PCH state is " follow-up have beep-page message ", after the time interval of specifying, to the upper paging receiving message content of HS-PDSCH (High-Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel (HS-PDSCH)) of bearing call message content.
In prior art, a kind of communication system as shown in Figure 4, comprising:
SRNC (Serving RNC, Serving RNC) refer to RRC (the Radio Resource Control between travelling carriage and network, unlimited resources control) destination node of agreement, the RRC context of travelling carriage is all stored in Serving RNC, and SRNC is unique interface that travelling carriage and core net communicate.
CRNC (Controlling RNC, control RNC), refer to that travelling carriage, due to reasons such as movements, has entered and belonged in this RNC community, travelling carriage has used the resource within the scope of this RNC, but when travelling carriage and core net communicate, still needs to pass through SRNC.
The Serving RNC of travelling carriage and control RNC may be same RNC, can be also different RNC.When the Serving RNC of travelling carriage with control RNC when inconsistent, Serving RNC can determine to initiate the process (being service radio network system repositioning process) of SRNS Relocation, the RRC context of travelling carriage is transferred to and controlled RNC from Serving RNC, thereby the control RNC before making becomes its Serving RNC.
Consider scene below: in a communication system shown in Fig. 4, travelling carriage is in URA_PCH state.Travelling carriage is set up RRC and is connected in radio network controller A scope Nei community, and radio network controller A is the Serving RNC of travelling carriage.But due to reasons such as the movements of travelling carriage, travelling carriage has resided in the community D under radio network controller B afterwards, and radio network controller B becomes the control RNC of travelling carriage.
In Fig. 4, radio network controller C scope Nei community E and the community D under radio network controller C belong to identical URA, also in the time that travelling carriage is carried out cell reselection from community D gravity treatment to community E due to reasons such as movements, although current wireless network controller C becomes the control RNC of travelling carriage, travelling carriage can't be initiated URA renewal process informing network side.
In the time that Serving RNC is received from the data for this URA_PCH state travelling carriage of core net or is called out, owing to can storing the RRC context of this travelling carriage in Serving RNC, therefore can know the RRC state of this travelling carriage and the URA identification information at place, so send beep-page message belonging in this URA community, specific implementation process as shown in Figure 5, comprises the following steps:
Step s501, Serving RNC sends paging request message to other the RNC that at least comprises a Ge Gai URA community, in this paging request message, carry: paging area (paging territory), be URA identification information, exhaled the IMSI of travelling carriage, and the information such as the DRX cycle parameter of this travelling carriage.Wherein, paging territory refers to the scope that need to send paging, can be URA mark, and mark that also can Shi Yige community, in the time controlling RNC and obtain paging territory, has been known and need in the scope of which community, have been sent this beep-page message.
Step s502, receive that the RNC of paging request message is (in the communication system of Fig. 4, RNC B and RNC C can receive this paging request message), according to the paging occasion of IMSI and DRX cycle calculation of parameter travelling carriage of being exhaled travelling carriage, and the information of the content of beep-page message and PI instruction is placed in PCH Frame and sends to base station by Iub interface.
Step s503, PCH Frame is received in base station, according to the content in PCH Frame, sends paging indication information in the relevant position of Page Indication Channel, sends the content of beep-page message at SCCPCH channel.
Step s504, travelling carriage is according to the IMSI of oneself, and the information such as DRX parameter calculate the opportunity of monitoring paging instruction, and judge whether to arrive SCCPCH channel paging receiving message content according to the information of paging instruction.
Introducing after enhancing paging characteristic, in above-mentioned step s502, receiving that the RNC of paging request also may be placed on the information of the content of beep-page message and PI instruction in HS-DSCH Frame and send to base station by Iub interface.
Step s503, HS-DSCH Frame is received in base station, according to the content in HS-DSCH Frame, sends paging indication information in the relevant position of Page Indication Channel, sends the content of beep-page message at HS-PDSCH channel.
Travelling carriage determines still paging receiving message on HS-PDSCH channel of paging receiving message on SCCPCH channel according to the cell capacity information of expressing in the system broadcast message of the ability information of oneself and current area.
In sum, realizing in process of the present invention, inventor finds that in prior art, at least there are the following problems: according to the description of existing protocol, if travelling carriage support strengthens the function of paging, and the relevant information in system broadcast message shows that the current resident community of travelling carriage is also while supporting enhancing paging function, travelling carriage is in the paging instruction listening on Page Indication Channel, the content that next can remove to answer on HS-PDSCH channel beep-page message.But the system broadcast message in the persistent district that travelling carriage receives is the configuration that comes from CRNC, current area supports enhancing paging can only show that CRNC supports to strengthen paging characteristic, can not show whether SRNC supports to strengthen paging characteristic.
Although CRNC can obtain travelling carriage and whether support to strengthen from travelling carriage carry information cell update or URA updating message the ability information of paging, then judges beep-page message is sent in to SCCPCH channel or HS-PDSCH channel according to the ability information of travelling carriage.But, if when travelling carriage was never initiated up access in the scope of current C RNC, be that travelling carriage cell reselection is to different RNS (Radio Network Subsystem, RNS) scope, but still belong to identical URA community, therefore need not initiate the process that URA upgrades.Therefore whether CRNC is iff supporting the ability information that strengthens paging to select paging channel according to this community, 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 community D gravity treatment to community E, because community D and community E belong to identical URA, therefore in the time that network side need to be to Mobile Origination paging, travelling carriage was not also initiated up signaling access in the scope of radio network controller C, so radio network controller C cannot learn the ability information of travelling carriage, also just cannot know after travelling carriage is received paging instruction and can go to monitor beep-page message on SCCPCH or HS-PDSCH channel, so there is the possibility of call loss.
Summary of the invention
The embodiment of the present invention provides a kind of method and system of definite paging transmission channel, to solve the ability information that cannot learn travelling carriage in prior art, also after cannot learning that travelling carriage receives that paging is indicated, the problem that can remove to monitor on SCCPCH or HS-PDSCH channel beep-page message.

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 paging characteristic.Described control RNC obtains and stores described travelling carriage and whether supports to strengthen paging characteristic and specifically comprise: described travelling carriage sends update request to described SRNC, and described request comprises whether described travelling carriage supports to strengthen the instruction of paging characteristic; Described SRNC sends paging request to described control RNC, carries described instruction in described request; Described control RNC obtains and stores described instruction.Or described control RNC receives the RRC message sending when described travelling carriage upgrades, obtain and store travelling carriage described in described message and whether support to strengthen the instruction of paging characteristic.Or, in travelling carriage certain community in URA, initiate up access and carry the ability information of supporting to strengthen paging characteristic; By the information interaction between RNC, the ability information of travelling carriage is obtained by all control RNC that have at least Yi Ge community to belong to this URA scope.
In the embodiment of the present invention one, a kind of travelling carriage is determined paging transmission channel method, as shown in Figure 6, comprises the following steps:
Step s601, travelling carriage carries the information of travelling carriage support enhancing paging performance capabilities in the uplink RRC (Radio Resource Control) signaling that sends to 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 in process of establishing, can be cell update message, can be URA updating message.
Step s602, the information that this travelling carriage support is strengthened paging performance capabilities by Serving RNC is stored in the RRC context that this travelling carriage is corresponding;
Step s603, controls RNC paging receiving request message;
In this paging request message, carry travelling carriage and whether support to strengthen the indication information of paging characteristic;
Or also can only carry travelling carriage support and strengthen the indication information of paging characteristic, while not carrying this information, think that travelling carriage do not support to strengthen paging characteristic.
Step s604, controls RNC according to the channel of the ability information decision transmission beep-page message in the ability information of travelling carriage and paging territory.
If travelling carriage support strengthens paging, and the community support enhancing paging characteristic of beep-page message transmission, on HS-PDSCH channel, send beep-page message;
If travelling carriage support strengthens paging, but paging characteristic is not supported to strengthen in the community that beep-page message sends, and on SCCPCH channel, sends beep-page message;
If travelling carriage does not support to strengthen paging, but enhancing paging characteristic is supported in the community that beep-page message sends, and on SCCPCH channel, sends beep-page message;
If travelling carriage does not support to strengthen paging, and beep-page message send community do not support to strengthen paging characteristic, on SCCPCH channel, send beep-page message.
That is, only have in the time that the community of travelling carriage and beep-page message transmission is supported to strengthen paging characteristic simultaneously, just on HS-PDSCH channel, send beep-page message.
In the embodiment of the present invention two, a kind of travelling carriage is determined paging transmission channel method, as shown in Figure 7, comprises the following steps:
Step s701, travelling carriage carries the information of travelling carriage support enhancing paging performance capabilities in the uplink RRC (Radio Resource Control) signaling that sends to network side;
This uplink RRC (Radio Resource Control) signaling is including but not limited to following RRC signaling: can be that RRC connects RRC in process of establishing and connects and set up demand signalling, can be that RRC connects and set up, and can be cell update message, can be URA updating message.
Step s702, controls RNC from the up RRC message described in step s701, and whether acquisition storing mobile station support to strengthen the information of paging characteristic.
Step s703, controls RNC paging receiving request message.
Step s704, s604 is identical with step.
The something in common of embodiment mono-and embodiment bis-is whether control RNC need to support to strengthen by certain approach acquisition travelling carriage the ability information of paging characteristic; And utilize the ability information of travelling carriage and need the community of issuing page message whether to support the ability information that strengthens paging characteristic jointly to judge issuing page message on which channel.Different, in embodiment mono-, be to obtain the paging request message sending from Serving RNC, and in embodiment bis-, be to obtain from travelling carriage sends to the up RRC message of network side.
In the embodiment of the present invention three, a kind of travelling carriage is determined paging transmission channel method, as shown in Figure 8, comprises the following steps:
Step s801, when Serving RNC is the new U-RNTI of mobile assignment at every turn, or each Serving RNC mark is while changing, carries SRNC and whether support to strengthen the instruction of paging characteristic in the RRC message that network side sends to travelling carriage.Wherein, described RRC message can include but not limited to following message: be switched 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 (RADIO BEARER RELEASE); Radio bearer is set up message (RADIO BEARER SETUP); Message (RRC CONNECTION SETUP) is set up in RRC connection; Transmission channel reconfiguration message (TRANSPORT CHANNEL RECONFIGURATION); URA upgrades acknowledge message (URA UPDATE CONFIRM); UTRAN moving notification message (UTRAN MOBILITY INFORMATION).
Step s802, travelling carriage can judge whether Serving RNC supports to strengthen paging by this instruction;
As the network side new U-RNTI that has been mobile assignment, but while but not carrying this instruction, travelling carriage can think that this Serving RNC do not support to strengthen paging characteristic.
Step s803, controls RNC and receives paging request message.
Step s804, controls RNC and determines paging channel according to the ability information of travelling carriage, sends beep-page message;
If controlling in RNC does not have storage whether to support to strengthen the information of paging about this travelling carriage, control RNC for this travelling carriage, on the relevant Page Indication Channel of its HS-PDSCH channel and the relevant Page Indication Channel of SCCPCH, all send paging indication information.
Control RNC in the time calculating paging occasion and PI bitmap (bitmap), to be exhaled travelling carriage according to two kinds of situations not supporting to strengthen paging characteristic and support to strengthen paging characteristic, calculate two paging occasion, two PICH No. SFN, and in these two paging occasion, all transmit corresponding paging instruction, show " follow-up have beep-page message " the information that comprises " beep-page message is at SCCPCH " in the extended bit of the relevant paging indicator channel frames of HS-PDSCH channel to travelling carriage.
Step s805 sends the content of beep-page message on SCCPCH channel.
Step s806, if travelling carriage support strengthens paging characteristic, travelling carriage can be read the information of " beep-page message is at SCCPCH " in paging instruction and the extended bit on the Page Indication Channel that HS-PDSCH channel is relevant.Thereby next to the content of paging receiving message on SCCPCH channel.
In embodiment tri-, the travelling carriage only meeting the following conditions can remove to read the extended bit in PICH frame: travelling carriage is in URA_PCH state, travelling carriage support strengthens paging characteristic, and paging characteristic is supported to strengthen in current community of living in, and it (may be because SRNC is the Rel7 RNC of version in the past that the Serving RNC of travelling carriage does not support to strengthen paging characteristic, or after Rel7 version but do not support to strengthen the RNC of paging characteristic), even if the discontented travelling carriage that is enough to condition is read this extended bit, also can ignore its implication.
Can know from above analysis, the paging that does not meet these conditions still can utilize HSDPA channel to issue; Even if meet these conditions, beep-page message still has an opportunity to issue at HSDPA channel, and this depends on whether control RNC understands the enhancing paging performance capabilities of travelling carriage, so can effectively utilize HSDPA characteristic.
In the embodiment of the present invention four, the travelling carriage that support in URA_PCH state strengthens paging characteristic recognizes that Serving RNC do not support to strengthen paging characteristic, and paging characteristic is supported to strengthen in current area, and travelling carriage is in SCCPCH channel paging receiving message.Control RNC in the time calculating paging occasion and PI bitmap, will be exhaled travelling carriage according to the travelling carriage processing of not supporting to strengthen paging characteristic.Detailed process as shown in Figure 9, comprises the following steps:
Step s901～s903 is identical with step s801～s803.
