Description
Technology neck city
The present invention relates to moving communicating field, particularly paging technique.
Background technology
Mobile communication technology entered since the second generation mobile communication (The Second Generation is called for short " 2G ") from 20 end of the centurys, had obtained developing rapidly.Increase along with number of users, and improving constantly to requirements such as class of business and performances, the 3G (Third Generation) Moblie that data transmission capabilities is stronger (TheThird Generation, be called for short " 3G ") entered the high speed development stage, moving communicating field presents by 2G progressively to the situation of 3G transition.
When the 3G system progressively entered commercialization, industry had begun Research on New work again, is referred to as super 3G (Super3G) technology, or the evolved technology of 3G, also is the E3G technology.
In order to guarantee the competitiveness of more longer time (as 10 years or longer), third generation partner program (3rd Generation Partnership Proiect is called for short " 3GPP ") started the LTE project since the second half year in 2004.
The state that a very important content is exactly an agreement in the LTE project is divided.At present according to terminal in moving process employed resource situation and with the degree of contact of network side, terminal is divided into three states, promptly divide amorph (LTE_detached), Idle state (LTE_idle) and activated state (LTE_active), correspond respectively to three similar states in existing Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access is called for short " the WCDMA ") network: divide amorph, Idle state and connected state (connected).Branch amorph (LTE_detached), Idle state (LTE_idle) and activated state (LTE_active) are Radio Resource control (Radio Resource Control, abbreviation " RRC ") state, because LTE does not also form practical standard at present, so three states are had different titles, but from the unanimity of saying so in fact.Generally speaking, network side is thought terminal deviated from network during the branch amorph, typical case be terminal closedown; Terminal has signed in to network during Idle state, but is not connected with network side, and network side is known the approximate location of terminal, can find terminal by paging, and typical situation is a terminal standby; Terminal has with network side and is connected during activated state, and typical situation is that terminal is being used wireless traffic, as makes a phone call.
In existing WCDMA system, terminal is when being in idle condition, cell paging channel (CELL_PCH) state and wireless access paging channel (URA_PCH) state, in order to economize on electricity, terminal adopts the mode of discontinuous reception (DRX) to receive data from network side.Network side is operated after public paging channel (Paging Channel is called for short " PCH ") goes up issuing page message, makes terminal can receive beep-page message when having data to be transferred to terminal accordingly.In order to reduce the time of terminal supervisory channel, for terminal improves effective operation of sleep mode, network side is before issuing page message, by Page Indication Channel (Page Indication Channel, be called for short " PICH "), provide paging indication (Paging Indicator is called for short " PI ") to terminal, notice terminal paging receiving message.Specifically, be on the paging occasion (paging occasion) of terminal in each DRX cycle under idle condition, CELL_PCH state and the URA_PCH state, the PI on the PICH channel is monitored.Wherein, paging occasion is that the value according to DRX calculates, and be that international mobile station identity number (InternationalMobile Station Identity, be called for short " IMSI ") according to this terminal calculates at the PI that the paging occasion terminal will read.If terminal is when monitoring PICH, the information of PI indication is " follow-up have beep-page message ", then by calculating paging message receiving occasion (Paging Message Receiving occasion), auxiliary publish control physical channel (Secondary-Common Control Physical Channel is called for short " SCCPCH ") to bearing call message is gone up paging receiving message (SCCPCH is the auxiliary publish control physical channel that Paging Control Channel is mapped to physical layer).For making terminal can accurately receive beep-page message from network side, network side and terminal are consulted the parameter of its DRX in advance, make network side can send PI in due course, and terminal also can and receive the one's own PI information of reception on the PICH in corresponding discovery constantly.
Wherein, the computing formula of paging occasion is as follows:
Paging occasion={ (IMSI/K) mod (DRX cycle length/PBP) } * PBP+n * DRX cycle length+Frame Offset
In the above formula, IMSI is an international mobile subscriber identification code; K is the number of the SCCPCH channel of available bearing call channel (Paging Channel is called for short " PCH "); DRX cycle length is discontinuous receiving cycle; PBP is a paging block periodicity, for drawing together Frequency Division Duplexing (FDD) (Freq terminal n eyDiVision Duplex is called for short " FDD "), PBP=1; Frame offset is vertical shift, and for FDD, vertical shift is 0, and for time division duplex (Time Division Duplex is called for short " TDD "), frame offset value is specified in system message.
The computing formula of paging message receiving occasion is as follows:
Paging message receiving occasion=paging occasion+NPICH+NGAP+{ (DRX Index modNp) mod NPCH) * 2
Wherein, NPICH is the frame number of bearing call indication frame, equals the repeat length of calling indicating frame; NGAP is the frame number between the frame of the frame of last bearing call indication of certain paging occasion and first bearing call message; DRX Index is discontinuous reception index, and its value is IMSI/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; NPCH is the number of paging group.NPICH, Np, NPCH issues in system message.
More than to terminal when discontinuous receive paging method and the computational methods of paging occasion be illustrated, multimedia broadcasting and the multicast service (MultimediaBroadcast/Multicast Service is called for short " MBMS ") that 3GPP is proposed is introduced below.
Multicast and broadcasting are a kind of technology that transmits data from a data source to a plurality of targets.In traditional mobile communications network, cell broadcaste service (Cell Broadcast Service is called for short " CBS ") allows low bit rate data to share broadcast channel to all users' transmissions by the sub-district, and this kind business belongs to information series business.
Now, people no longer are satisfied with phone and messaging service to the demand of mobile communication, and along with the fast development of internet (Internet), a large amount of mobile multi-media services emerge.The some of them mobile multi-media service requires a plurality of users can receive identical data, for example video request program, television broadcasting, video conference, online education, interactive game etc. simultaneously.These mobile multi-media services are compared with general data service, have characteristics such as data volume is big, longer duration, delay sensitive.Present Internet protocol (InternetProtocol, abbreviation " IP ") multicast and broadcast technology only are applicable to wired IP communication network, be not suitable for mobile communications network, because mobile communications network has particular network structure, functional entity and wave point, these are all different with the wire communication IP network.
In order to effectively utilize the mobile communications network resource, 3GPP has proposed the MBMS business of mobile communications network, thereby in mobile communications network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, improve utilization rate of network resource, the interface resource of especially eating dishes without rice or wine.The MBMS that 3GPP proposes can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of following mobile data development undoubtedly.
In the LTE project, the MBMS business also is a crucial business, in order to simplify the design of network configuration, people have proposed the notion of independent descending carrier MBMS, independent descending carrier is exactly separately to divide a frequency only to be used for the professional and relevant control data of MBMS transmission, and unicast data (unicast data) does not transmit on special carrier.
Yet, because private downlink carrier is a frequency that is specifically designed to the MBMS transmission business of dividing out when the network planning, for using private downlink carrier to receive the terminal of MBMS business, can't receive and share information transmitted on the carrier wave, as beep-page message (paging message) etc.Therefore, when terminal is accepted the MBMS business on special carrier, how to allow the effective incoming terminal of beep-page message become the focus of research.
At this problem, existing solution has two:
Scheme one: can receive paging indication and beep-page message normally in order to make those terminals of using private downlink carrier to receive the MBMS business, on special carrier, finish the transmission of beep-page message according to conventional mobile communications network (unicast networks) design one cover paging channel (comprising PCH, PICH etc.) and paging method, also promptly need to be the paging channel design of clean culture independent pilot tone and its channel architecture, yet this method can increase the complexity of system undoubtedly.
Scheme two: get back to terminal periodic unicast networks and monitor paging occasion on the PICH channel to have judged whether one's own paging.This method need not newly-increased channel, implement comparatively convenient, yet, because unicast networks and the different carrier wave of the professional use of MBMS, and general terminal can only be monitored a carrier wave simultaneously, terminal is got back to when monitoring the PICH frame in the unicast networks, and the MBMS business under the private downlink carrier can be interrupted, and has influenced the quality of MBMS business.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is that terminal and network side determine that terminal arrives the opportunity of sharing carrier sense in the time slot that does not receive the business that is carried on special carrier through consultation.Terminal does not need to receive the business in the special carrier during monitoring, thereby can not cause being carried on the interruption that the business of special carrier receives because of monitoring.Wherein, the business in the special carrier is MBMS, and shared carrier wave is the carrier wave of unicast networks.
According to inventive principle the first embodiment of the invention paging method is described below.
As shown in Figure 1, in step 11O, terminal was obtained the schedule information of MBMS before entering into special carrier.Specifically can be by reading Broadcast Control Channel (Broadcast Control Channel, be called for short " BCCH "), perhaps read the MBMS point to multiple spot control channel (MBMSpoint-to-multipoint Control Channel, be called for short " MCCH ") or the MBMS point obtain the schedule information of MBMS business to multiple spot scheduling channel (MBMS point-to-multipoint Schedule Channel is called for short " MSCH ").
Then enter step 120, terminal is initiated Radio Resource control (Radio Resource Control is called for short " RRC ") process, reports the schedule information of the MBMS that this terminal need receive to network side.Terminal can only report the ID of MBMS when reporting the schedule information of the MBMS that needs reception, find corresponding M BMS information by network side according to this ID, and this scheme is less to the demand of interface-free resources; Also can report the information that needs or do not need to receive MBMS on which time slot, use this scheme, the time parameter of monitoring can directly be determined in the base station according to the information that reports, no longer need to find corresponding M BMS information alternately with other network equipment, has simplified the processing of network side.In addition, the RRC process that terminal is initiated can be an existing RRC process in the prior art, as a cell updating course, also can be a new RRC process.If this moment, terminal was in idle condition, then terminal need be set up the RRC connection.
Then enter step 130, network side determines that according to the schedule information of the MBMS of terminal to report this terminal arrives the time parameter of the carrier sense of unicast networks in the time slot that does not receive MBMS.Determined time parameter has two kinds of situations: the one, receiving under the situation of conflicting according between paging occasion that prior art calculated and the MBMS business, the relevant parameter that can utilize existing paging occasion is as determined time parameter, as shown in Figure 2.The 2nd, receiving under the situation of conflicting according to having between paging occasion that prior art calculated and the MBMS business, that is to say, terminal is according to System Frame Number (the System Frame Number of the paging occasion correspondence that existing formula calculated, abbreviation " SFN ") there is the MBMS business to receive on, as shown in Figure 3, then determine this terminal time parameter to the carrier sense of unicast networks in the time slot that does not receive MBMS according to the schedule information of the MBMS of terminal to report by network side.Wherein, time parameter comprises the vertical shift and the Cycle Length of this terminal periodic to the carrier sense of unicast networks that does not have the professional transmission of MBMS in the special carrier.Time parameter by the network side decision-making is monitored can alleviate the calculation requirement to terminal, reduces the power consumption of terminal.
Can know the idle time slot that does not receive MBMS according to the schedule information of MBMS, these idle time slots normally periodically occur.And paging occasion=skew+n * Cycle Length, wherein skew and Cycle Length are variablees.The distribution of known idle time slot, asking the paging occasion that drops on fully in the idle time slot is a mathematical problem.This problem can have the solution of many kinds, for example, skew can be taken in the idle time slot, attempt all possible Cycle Length one by one, the Cycle Length that paging occasion drops in the idle time slot is fully noted, and this skew and these Cycle Lengths are exactly separating of the problems referred to above.And for example, if idle time slot is periodic, the minimum period of establishing idle time slot is M, and then separating of the problems referred to above can be: be offset to certain idle time slot, Cycle Length are k * M, wherein k is a natural number.
If the available time parameter that network side is determined has many groups, then select one group therein: select current one group of minimum time parameter of number of terminals of selecting this time parameter for use according to one of following mode; Or, select by the priority orders that presets; Or, select at random.Adopt first kind of mode to make respectively to organize the terminal number that distributes on the time parameter roughly even, the possibility that clashes during with the minimizing paging, and, because network side is known the time parameter of all terminal monitorings in a paging domain, so have the ability to select one group fully by the time parameter of minimum terminal use.
Then enter step 140, network side is handed down to this terminal with determined time parameter.
Then enter step 150, network side sends paging indication or beep-page message to this terminal according to determined time parameter on the SFN of correspondence.
Then enter step 160, terminal enters special carrier, and according to paging indication or the beep-page message of the time parameter that receives to the SFN of the carrier sense correspondence of unicast networks.Owing to monitor according to determined time parameter, terminal does not need to receive the business in the special carrier when monitoring, thereby can not cause the professional interruption that receives of MBMS in the special carrier because monitoring paging indication or beep-page message.
Network side and terminal can be calculated corresponding SFN according to following formula:
There is not the Cycle Length of the vertical shift+n * terminal periodic of the professional transmission of MBMS in the SFN opportunity of paging receiving (or be called)=special carrier, n=0,1,2 to the carrier sense of unicast networks ..., the maximum that SFN limits less than network side.
According to inventive principle the second embodiment of the invention paging method is described below.
The second embodiment of the invention and first execution mode are roughly the same, its difference only is, in the first embodiment, terminal was obtained the schedule information of MBMS before entering into special carrier, directly initiate the RRC process and give network side, enter special carrier afterwards and receive the MBMS business datum the MBMS reporting of scheduling information (SI); And in the present embodiment, terminal at first enters special carrier, receives the schedule information of MBMS afterwards, and gets back to the carrier wave of unicast networks at the time slot that does not receive MBMS, initiates the RRC process, reports the schedule information of the MBMS that needs reception to network side.
Specifically as shown in Figure 4, in step 401, terminal enters the special carrier network.
Then enter step 402, terminal receives the MBMS business datum that it need receive by MBMS point-to-multipoint service channel (MBMSPoint-to-Multipoint Traffic Channel is called for short " MTCH ").
Then enter step 403, terminal receives the schedule information of its MBMS business that need receive by MCCH.
Then enter step 404, terminal is got back to the carrier wave of unicast networks according to the schedule information of this MBMs at the time slot that does not receive MBMS, initiates the RRC process, reports the schedule information of its MBMS that need receive to network side.Terminal can only report the ID of MBMS when reporting the schedule information of the MBMS that needs reception, find corresponding M BMS information by network side according to this ID, and this scheme is less to the demand of interface-free resources; Also can report the information that needs or do not need to receive MBMS on which time slot, use this scheme, the time parameter of monitoring can directly be determined in the base station according to the information that reports, no longer need to find corresponding M BMS information alternately with other network equipment, has simplified the processing of network side.In addition, the RRC process that terminal is initiated can be an existing RRC process in the prior art, as a cell updating course, also can be a new RRC process.If this moment, terminal was in idle condition, then terminal need be set up the RRC connection.
Step 405 is similar to step 150 to step 407 and step 130, does not repeat them here.
In step 408, terminal is according to the time parameter that receives paging indication or the beep-page message to the SFN of the carrier sense correspondence of unicast networks.Owing to monitor according to determined time parameter, make terminal when monitoring, do not need to receive the business in the special carrier, thereby can not cause the professional interruption that receives of MBMS in the special carrier because monitoring paging indication or beep-page message.
Below the third embodiment of the invention paging method is described.
The third embodiment of the invention and first execution mode are roughly the same, and its difference only is that in the first embodiment, network side is directly determined time parameter according to the schedule information of the MBMS of terminal to report, and notifies this terminal definite time parameter; And in the present embodiment, network side is determined the time parameter that all are available according to the schedule information of the MBMS of terminal to report, and the time parameter that all are available is handed down to this terminal, selects one by this terminal from all available time parameters, as the final time parameter of determining.
Specifically as shown in Figure 5, step 501 and step 502 and step 11O and step 120 are similar, do not repeat them here.
Then enter step 503, network side determines that according to the schedule information of the MBMS of terminal to report this terminal arrives all available time parameters of the carrier sense of unicast networks in the time slot that does not receive MBMS.Determined time parameter comprises following two kinds of situations: the one, receiving under the situation of conflicting according between paging occasion that prior art calculated and the MBMS business, the relevant parameter that can utilize existing paging occasion is as available time parameter, as shown in Figure 2.The 2nd, receiving under the situation of conflicting according to having between paging occasion that prior art calculated and the MBMS business, that is to say, there is the MBMS business receiving on the SFN of terminal according to the paging occasion correspondence that existing formula calculated, as shown in Figure 3, then, determine that this terminal arrives other available time parameter of the carrier sense of unicast networks in the time slot that does not receive MBMS by the schedule information of network side according to the MBMS of terminal to report.Wherein, time parameter comprises the vertical shift and the Cycle Length of this terminal periodic to the carrier sense of unicast networks that does not have the professional transmission of MBMS in the special carrier.To determining all available time parameters, can alleviate calculation requirement by network side, reduce the power consumption of terminal terminal.
Then enter step 504, all up duration parameters that network side will be determined are handed down to this terminal.
Then enter step 505, terminal is selected one group from all available time parameters of being received.Concrete available by the priority orders selection of presetting, or, select at random.Make terminal to make a strategic decision by this mode, thereby make the result of decision be more suitable for the actual needs of terminal in conjunction with some extraneous informations of self.
Then enter step 506, the time parameter report network side that terminal will finally be selected.
Then enter step 507, network side sends paging indication or beep-page message to this terminal according to the time parameter of being received on the SFN of correspondence.
Then enter step 508, terminal enters special carrier, and according to paging indication or the beep-page message of the time parameter that receives to the SFN of the carrier sense correspondence of unicast networks.Owing to monitor according to determined time parameter, terminal does not need to receive the business in the special carrier when monitoring, thereby can not cause the professional interruption that receives of MBMS in the special carrier because monitoring paging indication or beep-page message.
Network side and terminal can be calculated corresponding SFN according to following formula equally:
There is not the Cycle Length of the vertical shift+n * terminal periodic of the professional transmission of MBMS in the SFN opportunity of paging receiving (or be called)=special carrier, n=0,1,2 to the carrier sense of unicast networks ..., the maximum that SFN limits less than network side.
Below the four embodiment of the invention paging method is described.
