The method and system that a kind of empty port load-supporting is set up

Technical field

The present invention relates to a kind of communication technology, relate in particular to the method and system that a kind of empty port load-supporting is set up.

Background technology

MCCH (MBMS control channel) is MBMS (multimedia broadcast multi-broadcasting business) control channel, and the UE (user terminal) of all reception MBMS business will read MCCH to obtain relevant various RRC (Radio Resource control) message of MBMS in the sub-district.New MBMS is professional or delete existing MBMS when professional setting up, and the RRC message on the MCCH can change; In order to guarantee the reliable reception of UE to MCCH, the message on the MCCH adopts the mode that repeats to send.Therefore need the transmission of scheduling RRC message on MCCH.

Whether MICH (MBMS indicating channel) is a physical channel, be used to indicate the RRC message on the MCCH relevant with each MBMS business to change.

Fig. 1 show MICH, MCCH the carrying and on the information-bearing process.Below with reference to Fig. 1 the last change in information situation of MICH, MCCH is described.

As shown in Figure 1, the last carrying of MCCH Access Info (access information) and Critical Info (key message), access information repeats to send with Access info period (access information cycle), and key message repeats to send with Repetition period (repetition period).Repetition period is the several times in access information cycle, and Modification period (modification cycle) is the several times of repetition period.In cycle, access information all may change at each access information; Key message each repetition period in a modification cycle all remains unchanged, and may change between the different modification cycles.

When the key message of certain MBMS business changed, the MICH bit of the service groups correspondence under this business is meeting set in the previous modification cycle, and the Change Information (change information) in this key message also can indicate.

Access information is RRC message MBMS ACCESS INFORMATION (MBMS access information), when receiving the UE number of a MBMS business in the statistics sub-district, is used to control UE and is linked into network.

Key message comprises following RRC message: MBMS MODIFIED SERVICESINFORMATION (MBMS revises business information), and it is used in reference to the MBMS business that relevant configuration information changes in the current modification cycle that is shown in; MBMS UNMODIFIED SERVICESINFORMATION (the unmodified business information of MBMS), it is used in reference to the MBMS business that relevant configuration information does not change in the current modification cycle that is shown in; MBMS GENERAL INFORMATION (MBMS general information); MBMS COMMON P-T-M RB INFORMATION (the public P-T-M of MBMS (putting multiple spot) radio bearer information); MBMS CURRENT CELL P-T-M RBINFORMATION (the P-T-M radio bearer information of MBMS current area), the P-T-M radio bearer information of described MBMS general information, the public P-T-M radio bearer information of MBMS, MBMS current area is used to indicate current area to comprise which MBMS business, and the channel configuration of these MBMS business; And MBMS NEIGHBOURING CELL P-T-M RB INFORMATION (the P-T-M radio bearer information of the neighbor cell of MBMS current area), it has comprised the existing MBMS business of current area, and the channel configuration of these MBMS business.

The process of setting up empty port load-supporting in the prior art is described below, and described empty port load-supporting is meant the P-T-M carrying of MBMS.

When initial, UE has activated the MBMS business, and it is in idle pulley, monitors the professional corresponding MICH bit of this MBMS.At this moment, the MBMS business does not begin transmission, and the P-T-M carrying is not set up.

After the professional beginning of MBMS, RNC (radio network controller) starts the process of setting up that the P-T-M carrying is set up:

RNC configuration network side and each relevant user entity of P-T-M carrying when the MBMS business datum arrives RNC, will send in the P-T-M carrying;

RNC is provided with in the modification cycle on the horizon the professional corresponding MICH bit with this MBMS;

RNC sends the RRC message that comprises this MBMS service configuration information in the next one modification cycle after MICH set.

UE has known that by monitoring MICH variation has taken place the MCCH information of this MBMS business, then reads MCCH in the next one modification cycle, obtains the P-T-M carrying configuration information of this MBMS business, and the P-T-M that arrives then carries up reception MBMS business.

Yet in above-mentioned existing MBMS technology, the RRC message on the MCCH repeated to send with the modification cycle, because the restriction of MCCH bandwidth, the repetition period can not be too short.Consider the reliable reception of RRC message, the number of repetition in a modification cycle can not be too little, so just causes the modification cycle can not be too little.Therefore, when using MBMS to carry to realize that MBMS is professional, the modification cycle of prior art regulation MCCH can be 1.28s, 2.56s, 5.12s, 10.24s.When the modification cycle is selected the shortest 1.28s, the eat dishes without rice or wine setup delay of downlink bearing passage reaches the twice of 1.28s when the longest (starting the empty port load-supporting passage when the modification cycle has just begun sets up, at next modification cycle change MICH, at change of following next modification cycle MCCH).Add other signaling procedures, can not satisfy the delay requirement of PTT (putting call through immediately after connection) call setup.

Embodiment

Understand and realization the present invention the existing embodiments of the invention of describing in conjunction with the accompanying drawings for the ease of persons skilled in the art.

The method for building up of empty port load-supporting of the present invention comprises that RNC to the carrying of the P-T-M between the hearer, will be described in greater detail below.

Have two kinds of reasons can cause the foundation of RNC to the P-T-M between hearer carrying, the one, the hearer P-T-M carrying that the speaker triggers set up flow process, the 2nd, the hearer P-T-M carrying that the hearer triggers set up flow process, respectively this situation is described in detail below.

1, the P-T-M carrying that triggers of speaker sets up flow process

When initial, UE is by carrying out point-to-point mutual with network, add a PTT (putting call through immediately after connection) service groups, and in this process, obtained PTT IMSI (PTT IMSI International Mobile Subscriber Identity), PTT DRX cycle length coefficient (the discontinuous receiving cycle length factor of PTT), page response probability initial value, page response probability increase step-length, page response repetition period, the page response maximum attempts of this PTT service groups.When not having the user to talk in the PTT group, hearer P-T-M carrying is not set up, and each UE is in idle pulley, and whether monitoring seek channel is paged to obtain its PTT IMSI that adds the PTT business.Particularly, each UE monitoring seek channel to be obtaining paged PTT IMSI, and judges whether the PTT IMSI of paging conforms to the PTT IMSI of the PTT business of its adding, if conform to, the PTT IMSI business that then UE added is paged, otherwise, continue monitoring seek channel.

When having the user to talk in the PTT group, SGSN (Serving GPRS Support Node) notice RNC starts the process of setting up that the P-T-M carrying is set up in the sub-district, describes the flow process of setting up of P-T-M carrying that the speaker triggers in detail below with reference to Fig. 2.

Step 1, RNC be by PAGING TYPE 1 message on the paging channel, the PTTIMSI that paging should business, and paging cycle obtains according to the discontinuous receiving cycle length factor of PTT, and according to the present invention, the discontinuous receiving cycle length factor of described PTT is 0-9.Described paging cycle can be obtained by following formula:

10* (2^ (the discontinuous receiving cycle length factor of PTT)) millisecond

For example, when the discontinuous receiving cycle length factor of PTT got 0, paging cycle was the 10*2^0=10 millisecond; When the discontinuous receiving cycle length factor of PTT got 2, paging cycle was the 10*2^2=40 millisecond.

Step 2, hearer UE be according to the PTT business that it added, listen to the PTT IMSI of paged PTT IMSI and the PTT business of its adding identical after, the paging that stops to monitor PTT IMSI begins to monitor descending CCCH (Common Control Channel); Be that probability is gone up to RNC transmission RRC CONNECTION REQUEST message (RRC (Radio Resource control) connection request message at RACH (Reverse Access Channel) with page response probability initial value simultaneously, wherein set up cause value and be PTT hearer's request, IMSI is PTT IMSI); UE is passing through page response after the repetition period, if on CCCH, also do not receive PTT RADIOBEARER SETUP message (the PTT radio bearer is set up message), making last time, the page response probability increases a page response probability increase step-length, send RRC connection request message as new probability to RNC, up to receiving that the PTT radio bearer is set up message or till RNC sends maximum attempts RRC connection request message.The relation that page response probability initial value, page response probability increase between step-length, the page response maximum attempts three can be determined by system, be made as more than or equal to 1 as making page response probability initial value+page response probability increase step-length * page response maximum attempts, promptly after UE receives beep-page message, just send RRC connection request message to RNC.

After step 3a-b, RNC receive this RRC connection request message, send the PTT radio bearer and set up message on CCCH, it comprises the configuration information and the PTT IMSI of the P-T-M carrying of this PTT business; If network side P-T-M carrying is not set up, RNC goes back each relevant user entity of configuration network side P-T-M carrying simultaneously.

Step 4, UE are receiving on the CCCH after the PTT radio bearer sets up message, if the PTTIMSI in the message conforms to the PTT IMSI that UE is added, then set up the configuration of the P-T-M carrying that obtains the PTT business the message from the PTT radio bearer, receive the P-T-M carrying according to P-T-M carrying configuration information then, and stop to send the RRC connection request to RNC.If the PTT IMSI in the message does not conform to the PTT IMSI that UE is added, then ignore this message.

2, the P-T-M carrying that triggers of hearer UE sets up flow process

When PTT call business well afoot, owing to carry because of not existing the UE that receives this PTT business not set up P-T-M the sub-district, at this moment, and when hearer UE enters this sub-district, the foundation of the P-T-M of triggering cell carrying.Describe the flow process of setting up that moves the P-T-M carrying that causes because of the hearer in detail below with reference to Fig. 3.

Step 1, hearer UE find that the movable cell of MBMS request user terminal of new sub-district this PTT business is set to ask the point-to-point wireless carrying, on RACH, send RRC connection request message to RNC, it comprise set up PTT hearer request set up cause value and PTT IMSI, and begin to monitor descending CCCH;

After step 2a-b, RNC receive this RRC connection request message, on CCCH, send the PTT radio bearer and set up message, it comprises the configuration information of the P-T-M carrying of PTT IMSI and this PTT business, and RNC goes back each relevant user entity of configuration network side P-T-M carrying simultaneously;

Step 3, UE are receiving on the CCCH after the PTT radio bearer sets up message, if the PTTIMSI in the message conforms to the IMSI that UE adds the PTT business, UE just sets up the configuration information that obtains P-T-M the message from the PTT radio bearer, receives the P-T-M loaded information according to P-T-M carrying configuration information then.

For guarantee a plurality of UE in the sub-district can both reliable reception PAGING TYPE 1 and the PTT radio bearer set up message, RNC repeats to send these two message with paging cycle and (before the P-T-M carrying is set up, only sends PAGING TYPE 1 message; After the P-T-M carrying is set up, after sending PAGING TYPE 1, send the PTT radio bearer after the radio frames in interval and set up message).

The channel configuration information of the P-T-M carrying of PTT business also repeats to send by the relevant configuration information on the MCCH except setting up the message transmission by the PTT radio bearer on CCCH, and its sequential as shown in Figure 4.The once transmission that on behalf of PAGING TYPE 1 and MBMS radio bearer, last each rectangle of CCCH set up.Corresponding bits set in an ensuing modification cycle to MICH, channel configuration information begins to send on MCCH in the modification cycle following closely, stops at CCCH simultaneously and goes up transmission.

In order to guarantee that each UE in the sub-district can both this beep-page message of reliable reception, RNC sends N usually, and (N is the positive integer greater than 1, it is fixed that it can be come by system, as being made as 5) inferior beep-page message, if RNC does not also receive the RRC connection request message of UE after sending N paging, stop at this sub-district and send beep-page message, the movable cell of MBMS request user terminal that MBMS revises in business information message and the unmodified business information message of MBMS is set to ask the point-to-point wireless carrying, represent that current this PTT business carries out, but the P-T-M carrying is not set up in this sub-district because there not being the user.

After P-T-M carrying was set up, RNC inquired about by the cycle counting (user terminal counting) of MBMS is machine-processed whether the number of users that this sub-district receives this PTT business is 0; If the PTT number of users is 0, delete the P-T-M carrying of this sub-district, the movable cell of MBMS request user terminal is set to ask the point-to-point wireless carrying.

Eat dishes without rice or wine to set up process according to above-mentioned, as follows to the time-delay analysis of setting up in the embodiment of the invention in the P-T-M load bearing process: suppose that the discontinuous receiving cycle length factor of PTT value is 3, then paging cycle is 80ms.UE receives that beep-page message receives that to RNC the time delay of RRC connection request message is 100ms, and RNC receives that RRC connection request message receives that to UE it is 200ms that the PTT radio bearer is set up the time delay of message.RNC set up the time of 400ms approximately to the P-T-M carrying of hearer UE like this, much smaller than existing 2.56 seconds.

The invention also discloses the system that a kind of empty port load-supporting is set up, comprise: user terminal, be used for sending wireless resource control connection request to radio network controller, and receive the putting call through immediately after connection radio bearer that radio network controller sends and set up message, and set up message according to the putting call through immediately after connection radio bearer and obtain point to multiple spot carrying configuration; Radio network controller is used to receive the wireless resource control connection request of user terminal, and sends the putting call through immediately after connection radio bearer with paging cycle to user terminal and set up message.

According to the present invention, give PTT IMSI of each PTT traffic assignments, utilization eat dishes without rice or wine discontinuous reception and paging flow process, RRC connection building process, by on paging channel, CCCH, sending message to UE, but fast notification is in the P-T-M carrying configuration information of the current PTT business of the UE of idle pulley, thereby realizes the quick foundation of the P-T-M carrying of UE; Setting up in the process of the P-T-M of UE carrying, by the UE of paging acquisition PTTIMSI, set up the P-T-M carrying again after the UE response of this PTT business of wait reception, if do not have UE to respond then do not set up P-T-M to carry, saved idle wireless resource; When hearer UE response paging, the method that adopts access probability progressively to increase has been avoided jam of ascending idle port.

Therefore,, on the basis of existing MBMS wireless access fidonetFido, change on a small quantity, just can realize the quick foundation of eat dishes without rice or wine hearer's carrying and speaker's carrying that PTT calls out according to the present invention.
