Embodiment
Below, describe in detail according to a preferred embodiment of the invention with reference to accompanying drawing.Below only explanation need to understand part according to action of the present invention, the explanation of under the prerequisite that does not influence emphasis of the present invention, omitting other parts.
The invention provides a kind of method that when a plurality of UE that join the MBMS service transmit the Paging Indicator of informing the paging information existence, can more effectively transmit.
Usually, in the mobile communication system, UE is in order to prevent unnecessary battery consumption, paging time point (Paging Occasion from the random time of prior appointment, be called " PO " below) reception PICH signal, when the relevant paging of the PICH of described reception signal shows (Paging Instance is called " PI " below) set point " 1 ", confirm to have paging.At this moment, decide described PO to begin time point by each UE identifier, described PO time point repeatedly may be the value of formulating at core net (Core Network) or UMTS wireless connections net (UMTS Territorial Radio Access Network).
Promptly, when having PI, described UE receives and is sent to common for the second time control physical channel (Secondary Common Control Physical Channel: conveyer channel (Paging Channel following being called " S-CCPCH "), be called " PCH " below)-the paging channel, whether judgement transmits the paging information (Paging Message) of described UE, but, conventional art is described as described, MBMS is the service to a plurality of UE, for the control information of described MBMS or be the service of a plurality of UE.Therefore transmit the PI that informs that described MBMS control information exists within a certain period of time repeatedly, make all UE that will receive described MBMS can both receive this PI.
Correspondingly, among the present invention to UE inform the PI that control information exists and receive described PI PICH, inform the NI that the control information relevant with MBMS exists and inform that the MICH that the control information relevant with described MBMS exists will distinguish physical channel.Here, informing that the Paging Indicator that the control information relevant with described MBMS exists calls notification indicator (Notification Indicator: following calling " NI "), the physical channel that receives described NI is called MBMS notification indicator channel (MBMS Notification Indicator Channel: following calling " MICH ").
And, among the present invention, the UE that supports described MBMS service confirms the described NI according to the MBMS service in order to receive described PI in the time point PO that opens (turn on) receiver, also judge whether to exist the relevant MBMS service paging of asking service with described UE simultaneously.That is, in described PO, carry out NI together, when preventing that described UE from receiving PI and NI, because of repeatedly opening the unnecessary UE power consumption that receiver power supply causes.
At this moment, described UE is by the existence of described NI affirmation to the control information paging of described MBMS service, receive to transmit MBMS control channel to the control information of MBMS (MBMS Control Channel: following being called " MCCH "), this MBMS use the conveyer channel that transmits by S-CCPCH forward near channel (Forward Access Channel: following being called " FACH ") drawing.That is, described UE is by the existence of described NI affirmation to the control information of the MBMS of described request.Therefore, when RNC transmits control information to any MBMS, transmit described NI within a certain period of time repeatedly, make the UE of request service can receive described NI.At this moment, described RNC can utilize whole 300 bits of described MICH to transmit NI.
At this moment, RNC at first, carries out forming in relevant unit the program of the MICH of common physical channel (Common Physical Channel) in order to pass through self-administered unit to the NI of UE transmission according to specific MBMS.
Fig. 3 is the information flow chart according to control information transmission/receiving course between the RNC of first embodiment of the invention composition MICH and the NodeB.
With reference to Fig. 3, RNC403 forms the physical channel that transmits NI by common conveyer channel device (Common Transport Channel Setup) (410 programs, 411 programs) at Node B402.Below " table 1a " and table " 1b " with MICH of the new qualification of physical channel explanation that transmits NI.
Correspondingly, the following describes the parameter of the existing common conveyer channel device request that is appended to (Common Transport Channel Setup Request).

Described<table 1a record pattern (Mode) the MBMS paging group number that is included in described MICH is shown.For example, if NICH Mode is set at 3, always co-exist in 3 MBMS paging groups.As mentioned above, when having 3 MBMS paging groups, RNC is set at 1 to any NI corresponding to a paging group, and transmits to Node B, and at this moment, Node B is set at 1 to 100 bits of the described NI of described NICH frame, and transmits to UE.
Described MBMS paging group identifier (paging Group ID) shows an above MBMS set of service that is assigned to notification indicator.Promptly, each MBMS that wants paging is consisted of a MBMS paging group unit, promptly be set at described MBMS paging group ID (MBMS Group ID) and transmit NI, and each MBMS service of described MBMS paging group identifier (paging Group ID) can be assigned to independently notification indicator.That is, set NI, can transmit to Node B with each MBMS service identifier (Service ID).
Even PO and the DRX cycle of a plurality of UE by the cycle of differing from one another receives NI, ensure that also the UE that belongs to the same MBMS paging group receives identical NI, for this reason, described paging cycle (PagingDuration) mean Node B transmit continuously NI during.Set described paging cycle (PagingDuration), make each MBMS paging group have the paging cycle that differs from one another.
At this moment, described MBMS paging group identifier (Paging Group ID) and described paging cycle (Paging Duration) are consisted of a pair of, can generate and have the tabulation (list) that maximum MBMS paging group is counted equal length.Or remove MBMS paging group identifier (Paging Group ID), according to the described MBMS paging group of order permutation identifier upwards, can generate only the have described paging cycle tabulation of (Paging Duration) according to permanent order.
And, when described MBMS paging group has identical paging cycle, described common conveyer channel device request (Common Transport Channel Setup Request) information comprises a paging cycle (Paging Duration) that is not tabulation, so can transmit.
Described<table 1b〉the change cycle (Modulation Period) is MBMS paging group or different MBMS service when having identical paging cycle, shows the term of this common paging cycle.The UE that receives specific MBMS service is in order to ensure the paging to its service, and Node B can not append or delete paging to new service in the change cycle.
Described<table 1a〉and<table 1b common physical channel identifier (Common Physical Channel ID) be the channel identifier of discerning described MICH.FDD (Frequency Division Duplex) DL (Downlink) channelization code (Channelisaion Code Number) shows the channelization Code Number that is assigned to described MICH.MBMS notification indicator channel power (MICH Power) shows the operable maximum electric weight that is assigned to described MICH.
With reference to Fig. 3, RNC403 transmits common conveyer channel device request (the Common Transport Channel Setup Request) information that comprises parameter, NI pattern or MICH pattern, paging cycle (Paging Duration) to Node B402 in program 410.In program 411, described Node B402 successfully forms the physical channel that transmits described NI, finishes described common conveyer channel device.
In the program 415, described Node B402 transmits NI from RNC403, correspondingly, upgrades system information module (being called " SIB " below the System Information Block) information of relevant MICH.In the program 417, described Node B402 broadcasts the SIB information of the whole unit that upgrades by described program 415 to the time point of appointment.In the described program 417, SIB information comprises MBMS NI Indicator, NI pattern (Mode) or MICH pattern.Here, whether described MBMS NI Indicator uses the designator of the new MICH that limits for MBMS uses paging.MICH pattern and described<table 1a〉and<show 1b described in parameter identical.
The UE that obtains SIB information by described program 417 periodically monitors MICH, confirms the existence according to the control information of MBMS.Here, the paging cycle of a MBMS paging group (Paging Duration) is decided by greatest length in the DRX cycle of the UE that belongs to the same MBMS paging group.Therefore, during activation MBMS service in, described paging cycle (Paging Duration) is not the value of fixing but the value that can change.
By described Fig. 3, Node B finishes to organize the preparation that transmits NI to specific MBMS repeatedly in described paging cycle, and UE also obtains receiving the physical channel information of NI by SIB, finish to receive the preparation of NI.
Therefore, RCN begins the MBMS session in order to inform, or informs that by MCCH carrying out aperiodicity MBMS information transmits, and transmits NI to UE.
Here, as described in Fig. 3 program 410, in described paging cycle (Paging Duration), RNC is inefficient to the mode that Node B transmits the NI value in each NICH frame.
Corresponding therewith, Fig. 4 illustrates that the RNC of notification indicator and the information between the Node B that transmit relevant MBMS paging group according to second embodiment of the invention transmit, receiving course.That is, Fig. 4 illustrates RNC and transmits NI value by Node B to the beginning time point, and Node B constitutes PICH and MICH frame repeatedly in described setting paging cycle, and to the method for UE transmission.In this method, Iub interface error causes Node B not receive the NI value that RNC transmits to the beginning time point, and also produce error when forming a plurality of PICH and MICH frame in paging cycle (Paging Duration) this moment, so can reliably transmit.
Therefore, as shown in Figure 4, the method for utilizing user plane (User Plane) Frame Protocol (Frame Protocol) to transmit NI NBAP (the Node B ApplicationPart) information that is utilized control plane (Control Plane) method that transmits described NI substitutes.
And, among the present invention, limit RNC with the new NBAP information that transmits described NI and upgrade (the NotificationInformation Update Response) information of replying to the announcement information that RNC transmits to announcement information update request (the Notification Information Update Request) information of Node B transmission with corresponding to described request information Node B.Can transmit described announcement information update request/reply (Notification Information UpdateRequest/Response) information by existing Node B control port (control port) or by the MBMS control port (controlport) that limits again according to the present invention here.
Between a RNC and NodeB, use described NodeB control port (control port) during the NBAP information of the irrelevant unit of transmission/receiving management particular UE.On the contrary, between a RNC and NodeB, use the MBMS control port (control port) that limits again during reception/transmission notification indicator (NotificationIndication) information by described NBAP information.
With reference to described Fig. 4, in the program 510, RNC503 transmits announcement information update request (Notification Information Update Request) information to NodeB503, makes Node B can form the MICH frame.Because carry out program 510, so can constitute physical channel by described Fig. 3 process.
The announcement information update request of described program 510 (Notification Information Update Request) information comprises NI information that is included in the MICH frame and paging cycle (Paging Duraion) information that optionally changes.Here, in order to show that described NI information uses following two kinds of methods.
First method: use bitmap (Bitmap)
Respectively distribute a bit according to MBMS paging classification.Therefore constitute the bitmap of forming by total NI mode bit., described bit is set at 0 o'clock here, does not transmit relevant NI, described bit is set at 1 o'clock, transmit relevant NI in the paging cycle of having set continuously.
Second method: use index (Index)
Be that category setting wants the MBMS of paging to serve according to the rules, and distribute the mode of the identifier of described group of difference.That is, once arrange the MBMS paging group,, be referred to as M BMS paging group identifier (Paging Group Identification) according to the upstream sequence number of getting.When comprising described paging group identifier (Paging Group ID), in the paging cycle of having set, transmit continuously relevant NI, when not comprising described paging identifier, do not transmit relevant NI.At this moment, belong to two MBMS services of identical paging group, in each change cycle, produce paging on the same position of frame.
Correspondingly, below<table 2a〉and<show 2b〉described announcement information update request (Notification Information Update Request) information one example is shown.

Described<table 2a〉and<show 2b each parameter set forth in the above, so omit its explanation.
Particularly, as described<table 2a〉and<table 2b〉shown in, when RNC transmits NI, use selectivity notification identifier information (Choice NI Information To Be Configured) parameter, according to circumstances in bitmap and index, select one, transmit to Node B.
And, as described<table 2a〉and<table 2b〉shown in, optionally comprise paging cycle (Paging Duration) parameter, transmit described announcement information update request (Notification Information Update Request) information, thereby according to MBMS paging classification change paging cycle (Paging Duration).
Correspondingly, described<table 2b〉shown in, the announcement information update request includes only the MBMS service groups in paging and will be from the MBMS service groups difference of new paging.That is, at described<table 2b〉in the new announcement information update request that transmitted can comprise the paging group tabulation (delta list) of appending or deleting after relatively with the paging group that has transmitted.
And, among the present invention, substitute described MBMS paging group identifier and can use MBMS identifier (MBMS Service ID).
, use the situation of described bitmap here, with the more effective use of the method Iub cable resource of all MBMS paging groups of paging simultaneously.
On the contrary, use the situation of described index, when the MBMS of while paging paging group number for a long time, have less bit and inform that whether paging exists, thereby, more effectively use the Iub cable resource.Therefore, the situation that RNC selects to use the situation of described bitmap adaptively and uses index is effectively used described Iub cable resource.
And, use the situation of described bitmap, RNC does not comprise described paging cycle (Paging Duration) information in described common conveyer channel device request (Common Transport Channel Setup Request) information or announcement information update request (Notification Information Update Request) information, can transmit bitmap by Node B.That is, transmit as the bitmap signal that transmits for existing Rel99PICH signal, RNC changes to 1 time point and changes to 0 time point from 1 from 0 to NI by Node B and transmits brand-new bitmap.
At this moment, described Node B from described program 510 reception notification information updating requests (Notification Information Update Request) afterwards, storage is to the composition information of MICH frame, and upgrades by announcement information in program 511 and reply (Notification Information Update Response) information answer.Promptly, the Node B of reception notification information updating request (Notification Information Update Request) information is in program 512, by each MBMS paging group in the paging cycle of having set from described information Connection Frame Number time point, the bit corresponding to continuous MICH frame NI is set at 1 transmits repeatedly.
Described paging cycle (Paging Duration) by program 410 common conveyer channel devices (Common Transport Channel Setup Request) information, is set by each paging group in Fig. 3 in advance.
For example, specific NI is set at 1 at CFN=0, and the MBMS paging group paging cycle (Paging Duration) of relevant described NI is set at 200 o'clock, the bit that is equivalent to the described NI of MICH frame the CFN value be 0~199 during, in all 200 frames, all be set to 1, and be sent to UE.At this moment, CFN=20 again NI be set at 1, described paging cycle (Paging Duration) is identical 200 o'clock, is equivalent to the bit of the described NI of described PICH frame or described MICH frame, the CFN value be 20~219 during, all be set to 1 in 200 frames, and be sent to UE.
And, among the present invention,, when the MBMS service that differs from one another is transmitted NI, transmit NI according to each MBMS service identifier (MBMS Service ID) by the new settings MICH of 300 bit lengths, use described MBMS paging group identifier to substitute.
