Technical field

The present invention relates to base station and a plurality of portable terminal and implement the mobile communication system of radio communication, relating in particular to provides the multicast and broadcast type data communications method that multimedia service is used and mobile communication system to portable terminal.

Background technology

Be called in the communication mode in the 3rd generation, calendar year 2001, Japan is with W – CDMA (Wideband Code Division Multiple Access: Wideband Code Division Multiple Access (WCDMA)) be put to commercialization.And, predetermined channel (the HS – DSCH:High Speed – Downlink Shared Channel: high-speed downlink shared channel) realize that the data of use down link send the HSDPA of further high speed (High Speed Down Link Pack Access: the high-speed downlink packet access) business that uses by add transmitted in packets at down link (individual data channel, unit control channel) that starts.Also propose and discuss the data that make up direction to send HSUPA (the High Speed Up Link Pack Access: the High Speed Uplink Packet access) mode that further high speed is used.W – CDMA is that (3rd Generation Partnership Project: the 3rd generation partner plan) communication mode of regulation collects in present the 6th edition standard book mobile communication system standardisation bodies 3GPP.

Again, among the 3GPP, as the communication mode different from W – CDMA, radio zone and the whole system that comprises core net formed to study be called " Long Term Evolution: Long Term Evolution " (LTE) and " System Architecture Evolution: system architecture evolution " new traffic mode (SAE).Among the LTE, access way, wireless channel composition and agreement are different from current W – CDMA (HSDPA/HSUPA).For example, in the access way, W – CDMA employing code division multiple access (Code Division Multiple Access), and LTE uses OFDM (Orthogonal Frequency DivisionMultiplexing: Orthodoxy Frequency Division Multiplex), use SC – FDMA (Single Carrier Frequency Division Access: single-carrier frequency division multiple access) at up direction at down direction.And the bandwidth of W – CDMA is 5 (MHz), and LTE uses 1.25/2.5/5/10/15/20MHz.Again, only use the packet communication mode among the LTE, but not the such circuit switching of W – CDMA.

Because LTE uses the new core net different from the core net (GPRS) of W – CDMA to consist of communication system, defines so be used as the independently wireless access network that separates with W – CDMA net.Thereby, in order to distinguish with W – cdma communication system, will (User Equipment: the base station that subscriber equipment) communicates be called eNB (E – UTRAN Node B:E – UTRAN Node B), will control with a plurality of base stations base-station control apparatus (the Radio Network Controller: radio network controller) be called aGW (Access Gateway: IAD) of the exchange of data and user data with mobile terminal UE in the communication system of LTE.The multicast and broadcast type multimedia service of implementing in the communication system of this LTE be called as E – MBMS (Evolved Multimedia Broadcast Multicast Service: evolutionary multimedia broadcast multicast business), to a plurality of portable terminals transmit news, the large capacity broadcasted content such as weather forecast, mobile broadcast.Be referred to as one-to-many (Point to Multipoint) business.The base station with E – MBMS data-mapping DSCH Downlink Shared Channel) or MCH (Multicast Channel: multicast channel), issue portable terminal to DL – SCH (Downlink Shared Channel:.Again, LTE not only provides broadcasting communication professional, and the communication service to indivedual portable terminals in a plurality of portable terminals is provided.To be called to the communication service of indivedual portable terminals clean culture (Unicast) business.LTE is different from W – CDMA, there is not separate channel (the Dedicated Channel towards individual other portable terminal in transmission channel, the physical channel, Dedicated Physical Channel: dedicated channel, DPCH), so implement the data of indivedual portable terminals are sent with common signal channel (shared channel).

Patent documentation 1 discloses in the communication system of cdma2000 mode, is just processing the method for one to one (Point to Point) communication of sound conversation at the portable terminal of receiving broadcast service (Broadcast service).In the non-patent literature 1 in the regulation LTE system minimum ability of the received bandwidth of portable terminal (Minimum Capability) be 10MHz, the adaptive-bandwidth of base station is changed to maximum 20MHz (being 1.25/2.5/5/10/1520MHz).In addition, non-patent literature 2 discloses basis from the treatment step of the eNode B of the information enforcement of the necessity of the expression reception E – MBMS business of portable terminal transmission.Yet non-patent literature 2 does not disclose the detailed step that receives simultaneously E – MBMS business and unicast service usefulness.

Again, non-patent literature 3 discloses and sends paging message (Paging Message) and broadcast message (Broadcast information), to realize the portable terminal low power consumption.Yet, do not disclose the distinctive problem of this LTE of bandwidth that the received bandwidth of portable terminal is used less than the base station.Do not disclose position on the frequency axis and the relation of paging message yet.Non-patent literature 4 discloses the PCH sending method that is conceived to the UE position on the frequency axis.Disclose again the mobile terminal locations side is sent paging designator (Paging Indicator).Yet, disclose problem or its solution that the portable terminal that is receiving E – MBMS business receives information (paging message, the paging designator etc.) usefulness that is used for the incoming call processing.

Fig. 5 is the key diagram of relation that the received bandwidth of the bandwidth of base station and portable terminal is shown.Stipulate in the LTE system: the bandwidth of base station can be selected and utilization from 1.25/2.5/5/10/15/20MHz.The received bandwidth of portable terminal is specified to maximum 20MHz, supports at least 10MHz.The received bandwidth of portable terminal is during less than the bandwidth of base station, portable terminal and base station negotiate, and mobile between position (position), namely portable terminal changes the processing of the centre frequency of wireless receiving and dispatching frequency.This processing is called readjustment (re-tune).Among Fig. 5, as an example, the bandwidth that the base station is shown is that the received bandwidth of 20MHz, portable terminal is the situation of 10MHz and 20MHz.The received bandwidth of portable terminal is in the situation of 10MHz, can not receive simultaneously whole frequency bands to the 20MHz bandwidth of base station, so use the 10MHz frequency range to communicate.In the case, the position of the 10MHz that communicates is not limited to 1, according to following the example of of centre frequency, exists a plurality of as the slot # 1 among the figure, #2, #3.Moreover the received bandwidth of portable terminal is in the situation of 20MHz, and is consistent with the bandwidth of base station, so can use the whole transmission bandwidth from the base station.In the case, do not need above-mentioned readjustment.

Below, the received bandwidth that portable terminal 3 is described is that the bandwidth of 10MHz, base station 2 is judged the no processing that can receive E – MBMS business of portable terminal when being 20MHz.Fig. 6 is the key diagram that the E – MBMS contents table that portable terminal is distributed is shown.Fig. 7 is the key diagram that the position on the frequency axis of distributing to E – MBMS business is shown.

The bandwidth of base station is that the received bandwidth of maximum 20MHz, portable terminal is in the situation of 10MHz, the situation that the frequency utilized bandwidth portable terminal that exists some E – MBMS content (program) to use can not receive.Existing W – CDMA technology all is 5MHz because the received bandwidth of the bandwidth of base station and portable terminal is equal, does not consider to address the above problem, and portable terminal can not judge whether to receive specific E – MBMS content.Therefore, in order to judge whether to receive specific E – MBMS content in the mode of considering the ability (can receive bandwidth) that portable terminal represents, from the E – MBMS contents table that the base station is distributed portable terminal, (namely be used for receive and dispatch this content) the frequency utilized bandwidth of adding that each content uses with corresponding relation ground with each E – MBMS content is as parameter.Comprise the frequency utilized bandwidth that each E – MBMS uses in E – MBMS contents table in the mode of being used as parameter like this, thereby portable terminal can judge whether to receive specific E – MBMS content in the mode of considering received bandwidth own.

Exist E – MBMS contents table to add towards the situation of the unicast service of certain specific portable terminal again.For example, in the situation of the E – MBMS content that utilizing communicates by letter sells, consider that the user is with reference to the situation of the details of certain commodity (suitcase).In the case, portable terminal sends the up direction (portable terminal of specifying " suitcase " according to the indication from the user

Network side) unicast data.The network side of the unicast data that mobile terminal receive sends is used as the details of " suitcase " as down direction (network side

Portable terminal) unicast info sends.At this moment, with the past specific user's transmission of asking this information of the details of " suitcase ".Receive to add like this E – MBMS content of unicast service, can on the disposal ability of hardware or software, process simultaneously the professional and unicast service of E – MBMS as prerequisite take portable terminal.Yet portable terminal can not judge that specific E – MBMS content transmitting-receiving is with unicast service.

Therefore, in order to judge whether to receive in the mode of the ability of portable terminal (here as considering the disposal ability of hardware and software) itself the E – MBMS content with unicast service, from the E – MBMS contents table that the base station is distributed portable terminal, comprise itself whether with the parameter (information that has or not individual communication) of unicast service with each E – MBMS content with corresponding relation ground.Like this, in E – MBMS contents table, comprise expression whether with the parameter of unicast service with each E – MBMS content with corresponding relation ground, thereby portable terminal can judge whether to receive specific E – MBMS content in the mode of the disposal ability (whether can receive simultaneously E – MBMS and unicast data) of considering itself.

Bandwidth of base station is that maximum 20MHz, portable terminal can receive in the situation that bandwidth is 10MHz, and receiving position (UE position) imagination of this portable terminal on frequency axis is shown in Figure 8 follows the example of 3 different receiving positions because of centre frequency.Thereby having UE position for example is the problem that the portable terminal of position 1 can not receive the E – MBMS content that the frequency band that utilizes position 2 (the professional position of E – MBMS) sends.In order to address this is that, portable terminal preferably can judge whether to receive specific E – MBMS content in the mode of considering the professional position of UE position and E – MBMS.Therefore, for portable terminal can judge whether to receive specific E – MBMS content, from the E – MBMS contents table that the base station is distributed portable terminal, (being used for this content of transmitting-receiving) the E – MBMS business position that comprises that each content uses with corresponding relation ground with each E – MBMS content is as parameter (content transmission band information).Comprise the professional position of E – MBMS as parameter in E – MBMS contents table like this, thereby portable terminal can judge whether to receive specific E – MBMS content in the mode of considering UE position own.

Fig. 6 illustrate an example above illustratedly comprise like that the frequency utilized bandwidth, whether with unicast service, the professional position of the E – MBMS E – MBMS contents table as parameter.Moreover E – MBMS contents table needn't comprise whole above-mentioned parameters, can use separately certain parameter, also use capable of being combined.And above-mentioned parameter does not add as the parameter in the E – MBMS contents table, and the portable terminal of issuing a separate notice also can be obtained same effect.Again, above-mentioned explanation is that the situation of 10MHz is illustrated to the received bandwidth of portable terminal, but also can use the thought that discloses in the above-mentioned explanation in the different communication system of the bandwidth of base station and portable terminal.

The concrete processing of the portable terminal of the E – MBMS contents table of using Fig. 6 then, is described.Fig. 8 is the flow chart of processing that the explanation frequency band can receive the portable terminal of E – MBMS business.Fig. 9 is the flow chart that further describes content shown in Figure 8.In the step 1 of Fig. 8, for example 2 (eNode B) are sent to portable terminal 3 to service center 5 such networks through the base station with E – MBMS contents table; In the step 2, portable terminal 3 receives E – MBMS contents table.Base station 2 can receive E – MBMS contents table simultaneously with portable terminal 3.This E – MBMS contents table comprises the frequency utilized bandwidth, whether with all or part of of unicast service, these 3 parameters of the professional position of E – MBMS.And above-mentioned parameter also can not be included in the E – MBMS contents table, and separates transmission with E – MBMS contents table.

The MCH that E – MBMS contents table can be used as transmission channel notifies, and also available BCH, DL – SCH notify.Again, consideration can be mapped to the MCCH as logic channel (Logical Channel), and is mapped to the method that the IP head is notified.Portable terminal 3 receives E – MBMS contents table, and the desired E – MBMS content that then will receive in step 3 selection judges whether to receive the processing of the E – MBMS content of selecting in step 4.The detailed condition of the processing of description of step 4 among Fig. 9.The judged result of step 4 is in the time of receiving the E – MBMS content of selecting, and portable terminal 3 sends E – MBMS in step 5 and receives request, wishes the E – MBMS content that receives with reception.The processing that send to be used for receives the reception request of E – MBMS content is called logins (entry).Sometimes will login to be called and order usefulness (subscribe), activation (activation).The E – MBMS that sends at service center 5 mobile terminal receives 3 receives request.Except service center 5 receptions were logined, base station 2 also can receive.Can will notify the calculating (Counting) that starts E – MBMS content reception and login the while or issue dividually base station 2 again.

Fig. 9 is the flow chart of processing that is shown specifically the step 4 of Fig. 8.In the step 1 of Fig. 9, the received bandwidth of the frequency utilized bandwidth of the E – MBMS content of hope and portable terminal is compared and considers, and judge whether to receive the E – MBMS content of wishing.The judgement of this step 1 is with reference to this parameter of frequency utilized bandwidth of figure 6.For example, the received bandwidth of portable terminal is in the situation of 10MHz, and the content that is judged as the frequency utilized bandwidth and is 20MHz number can not receive the film of CH3.Step 1 is judged as in the situation that can receive, execution in step 2.In the step 2, judge that whether the E – MBMS content of wishing is with unicast service.The judgement of this step 2 with reference to figure 6 whether with this parameter of unicast service.In the situation of E – MBMS content with unicast service of wishing, execution in step 3.On the other hand, in the situation of unicast service, execution in step 4.

In the step 2, the E – MBMS content of hope judges whether to receive simultaneously E – MBMS data and unicast data in step 3 during with unicast service.This is because as long as portable terminal can not receive E – MBMS data and unicast data simultaneously, and is just fully meaningless with the E – MBMS content of unicast service.Carry out this processing with the hardware of considering portable terminal, the mode of software disposal ability.The judged result of step 3 is that portable terminal has in the time of receiving simultaneously E – MBMS data and unicast data the processing of execution in step 4.The judgement of this step 4 is with reference to this parameter of the professional position of E – MBMS of figure 6.For example, be judged as: the UE position is that the portable terminal of position 1 judges that the weather forecast can receive E – MBMS service digit and to be set to 1 content sequence number CH1, the live coverage of baseball of CH2, the communication of CH4 sells.So far, when execution in step 1 was judged as portable terminal and can receives the E – MBMS content of wishing to the result of the series of steps of step 4, portable terminal sent E – MBMS to network side and receives request (step 5 of Fig. 8).On the other hand, when being judged as portable terminal in step 1,3,4 the arbitrary step and can not receiving the E – MBMS content of hope, be judged as and receive in the step 4 of Fig. 8.

In the step 4 of Fig. 9, portable terminal is in the time of can not receiving the E – MBMS content of hope, can be judged as " can not receive on the UE position of present situation ", but not only be judged as " can not receive " and end process according to the professional position of E – MBMS and the UE position judgment of itself.In the case, portable terminal is in order to change the UE position to base station requests, from portable terminal to " the UE position movement request " of base station notice to the professional position of E – MBMS of hope.When the negotiation result of base station and portable terminal, base station were accepted the request of UE position movement, portable terminal changed by making centre frequency, thereby obtains the effect that receives the E – MBMS content of wishing the setpoint frequency of UE position change frequency conversion part 11.This processing is called readjustment (re-tune).

Illustrated as mentioned, utilize in the situation of E – MBMS business in the communication system of LTE that the bandwidth of the received bandwidth of portable terminal and base station can be different, portable terminal is judged the E – MBMS content that judges whether can receive hope in the mode of the ability of considering portable terminal itself, so network is not notified the reception request of the E – MBMS content that the ability of portable terminal can not receive.Thereby the Radio Resource this respect is favourable effectively utilizing.And, in the time of can not receiving the E – MBMS content of hope because the UE position of portable terminal is different from the position of the E – MBMS content of hope (the professional position of E – MBMS), the base station is sent the request of UE position movement, thereby obtain the effect that can receive the E – MBMS content of wishing.

Execution mode 2

Execution mode 1 the bandwidth of the received bandwidth of portable terminal and base station can be different the communication system of LTE in, portable terminal itself judges whether to receive specific E – MBMS content or noly can receive simultaneously E – MBMS business and unicast service.And, in order to judge at portable terminal, with the frequency utilized bandwidth of E – MBMS content with whether be used as parameter with unicast service and append the E – MBMS contents table of portable terminal being distributed from network side.Yet above-mentioned processing may not need portable terminal itself to carry out, also can be in the base station or aGW, the such network side of service center carry out.

Below, the network side of illustrate in the base station, aGW, service center are such is implemented judging whether certain portable terminal can receive the situation of E – MBMS business.Figure 10 is the key diagram that the terminal ability information (UE capability) of portable terminal transmission is shown.The bandwidth of base station is that the received bandwidth of 20MHz, portable terminal is in the situation of 10MHz, has the frequency utilized bandwidth of using owing to E – MBMS content (program), the situation that portable terminal can not receive.Yet, as long as the received bandwidth of nonrecognition portable terminal just can not judge whether certain portable terminal can receive E – MBMS content at network side.Therefore, whether can receive specific E – MBMS content in order to judge portable terminal, portable terminal is toward base station, aGW or the such network side of service center, can receive bandwidth and be used as terminal ability information (UE Capability) and be sent to network side.

Again, existence is added towards the situation of the unicast service of certain specific portable terminal to E – MBMS content.Yet portable terminal does not mean that the E – MBMS content of this terminal transmission with unicast service in the situation that does not have the ability that can process simultaneously E – MBMS business and unicast service aspect hardware or the software., network side can not judge whether certain portable terminal has the ability that can process simultaneously E – MBMS business and unicast service.Therefore, certain portable terminal information that will represent whether to have the ability that can process simultaneously the professional and unicast service of E – MBMS is used as terminal ability information and is issued network side.As terminal ability information, also can notify the UE position (selection band information) of explanation in the execution mode 1 again.Can notify dividually above-mentioned parameter (can receive bandwidth, whether can process simultaneously E – MBMS and clean culture, UE position) with terminal ability information.And, can all not use above-mentioned parameter, and use its part.Above-mentioned explanation is that the situation of 10MHz is illustrated to the received bandwidth of portable terminal, but the base station communication system different from the bandwidth of portable terminal can be used the thought that discloses in the above-mentioned explanation.

Figure 10 is the key diagram of terminal ability information that the portable terminal of network side reference is shown.Comprise the information that can receive bandwidth and represent whether to have the ability that can process simultaneously E – MBMS business and unicast service (for example receiving simultaneously E – MBMS data and unicast data) in the table shown in Figure 10, their terminal ability information is recorded in portable terminal accordingly.Table shown in Figure 10 is the table in the network side reference, can make according to the terminal ability information that portable terminal is issued network side.Figure 11 is that explanation judges whether certain portable terminal can receive the flow chart of processing of the base station of E – MBMS business.In the step 1 of Figure 11, portable terminal 3 is issued base station 2 and the such network of aGW1 with terminal ability information (UE Capabilities).In the step 2, the terminal ability information that base station 2 receives from portable terminal 3.Particularly, portable terminal 3 utilizations are called the agreement of RRC (Radio Resource Control: Radio Resource is controlled) and with layer 3 message the base station are notified.(Media Access Control: the media access control) signaling is from the method for portable terminal informing base station also can to consider to be used as MAC.The terminal ability information that sends in the step 1 comprises the information that can receive bandwidth and whether have the ability that can process simultaneously E – MBMS business and unicast service.

In the step 3, for example 2 (eNode B) issue portable terminal 3 to service center 5 such networks through the base station with E – MBMS contents table.In the step 4, base station 2 receives E – MBMS contents table; In the step 5, portable terminal 3 receives E – MBMS contents table.The E – MBMS contents table that portable terminal 3 receives is identical with execution mode 1, also can comprise the frequency utilized bandwidth, whether with all or part of of unicast service, these 3 parameters of E – MBMS business position, but present embodiment is not must be like this.This is because implement the judgement processing that portable terminal carries out with reference to above-mentioned parameter in the execution mode 1 at base station 2 network sides such as grade.This situation be owing to must cut down the amount of information in the interval (between base station and the portable terminal) that must send as wireless signal, thus effectively utilize aspect the Radio Resource favourable.Particularly, for example utilize and be called NBAP (Node B Application Part: agreement node B application part) is used as E – MBMS contents table as layer 3 message from network informing base station 2.

In the step 6, portable terminal 3 to be wished the desired E – MBMS content that receives and is received the E – MBMS content of wishing reception in order to select, sends E – MBMS in step 7 and receive request.Particularly, for example portable terminal 3 utilizes the agreement that is called RRC (Radio Resource Control: Radio Resource is controlled), layer 3 message is used as in E – MBMS reception request is sent.Also can consider to be used as the method that the MAC signaling is notified.The E – MBMS that base station 2 mobile terminal receives 3 send in the step 8 receives request.Consider that this E – MBMS receives request and uses and calculate (Counting), login (be also referred to as Entry, order usefulness, activation) etc.

In the step 9, base station 2 one sides are with reference to table shown in Figure 10, and one side judges whether portable terminal 3 has the ability that receives desired E – MBMS content.Particularly, base station 2 according to desired E – MBMS content whether with unicast service, the frequency utilized bandwidth of desired E – MBMS content and the received bandwidth of portable terminal, and whether portable terminal can receive E – MBMS data and these viewpoints of unicast data simultaneously, judges whether to receive desirable E – MBMS content.Again, in the situation of notice UE position, base station 2 is judged with position (the professional position of E – MBMS) and the mode of UE position of considering the E – MBMS content that portable terminal is selected.

In the step 9 of Figure 11, the base station be judged as portable terminal 3 can not mobile terminal receive the 3 E – MBMS contents of selecting, then in step 10,2 pairs of portable terminals in base station 3 send the notice that does not allow E – MBMS to login, refusal is logined.On the other hand, the base station is judged as the E – MBMS content that portable terminal 3 energy mobile terminal receives 3 are selected in the step 9, then portable terminal 3 is carried out E – MBMS initiation of services and processes.Yet, can be judged as " can not receive on the UE position of present situation ", but not step 10 sends notice and the end process that does not allow E – MBMS to login like that.In the case, if change the UE position, the base station judges whether to receive desired E – MBMS content,, then can process (for example, portable terminal being allowed to reset) if can receive, and makes the professional position of E – MBMS and UE position consistency.

Moreover, be base station 2 to be shown judge whether certain portable terminal can receive the flow chart of the processing of E – MBMS when professional based on the above-mentioned explanation of Figure 11, process but aGW1, service center are carried out judge, but not base station 2.Figure 12 is that explanation judges whether certain portable terminal can receive the flow chart of processing of the network of E – MBMS business.Figure 12 moves on to network this point difference in each step that base station 2 is carried out of Figure 11, but the content of its step is identical, so detailed.

Illustrated as mentioned, the bandwidth of the received bandwidth of portable terminal and base station can be different the communication system of LTE in utilize in the situation of E – MBMS business, base station, aGW service center etc. judge in the mode of the ability of considering certain portable terminal whether certain portable terminal can receive desired E – MBMS content.Again, in the time of can not receiving desired E – MBMS content because the UE position of portable terminal is different from the position of desired E – MBMS content (the professional position of E – MBMS), if control, make the base station change the UE position to portable terminal, just have the effect of the variation that enlarges the E – MBMS content that portable terminal can utilize.

Execution mode 3

Execution mode 1 with 2 the bandwidth of the received bandwidth of portable terminal and base station can be different the communication system of LTE in, judge whether portable terminal can receive specific E – MBMS content or noly can receive simultaneously E – MBMS business and unicast service.And in the execution mode 1, portable terminal itself is implemented above-mentioned judgement; In the execution mode 2, base station or aGW, service center are implemented above-mentioned judgement.Below, illustrate that the portable terminal that receives E – MBMS data (comprising control information) starts the step of the such unicast data reception of for example sound conversation.

Figure 13 illustrates the flow chart whether portable terminal that judgement utilizing E – MBMS business can utilize the processing of unicast service.Among Figure 13, the user preferentially utilizes which side prior information (step 11) of the professional and unicast service of E – MBMS to base station notice expression.The prior information (step 12) that the base station mobile terminal receive sends.Utilization is called the agreement of RRC (Radio Resource control), and this prior information is used as layer 3 message informing base station.Also available method of being used as MAC (media access control) signaling base station etc.According to this prior information, when receiving E – MBMS content, portable terminal produces in the situation of the such incoming call of sound conversation, control, make the preferential and refusal conversation incoming call of reception of E – MBMS content, or make sound conversation incoming call and end the reception of E – MBMS content.

The portable terminal that is receiving E – MBMS content is used for the information (paging message, paging designator etc.) that (paging) processed in incoming call by receiving, and identification produces for example such indivedual incoming calls to this terminal of sound conversation.In the step 1 of Figure 13, portable terminal judges whether to receive the information that is used for this TV station incoming call processing.When portable terminal receives the information that is used for the incoming call processing (step 1 is yes), in step 2, portable terminal is judged except the current E – MBMS data that receiving, whether is also carried out the reception of unicast data.Figure 14 illustrates the detailed condition of the judgement processing of this step 2.Figure 14 illustrates the flow chart whether portable terminal that judgement utilizing E – MBMS business receives the processing of unicast data.In the step 1 of Figure 14, in order to utilize simultaneously E – MBMS business and unicast service, judge whether the ability of portable terminal is enough.The ability of portable terminal enough (being yes in the step 1) then in step 2, judges whether the user allows to receive simultaneously E – MBMS business and unicast service.

The user allows to receive simultaneously the professional and unicast service (being yes in the step 2) of E – MBMS, then the base station notice is received unicast data, in order to except E – MBMS business, also utilize simultaneously unicast service (step 4 of Figure 13).On the other hand, when the ability of portable terminal is not enough (being no in the step 1) or when not allowing to receive simultaneously the professional and unicast service of E – MBMS (being no in the step 2), judges whether to set in E – MBMS business and the unicast service and preferentially utilize E – MBMS data (step 3 of Figure 13).Set for and preferentially utilize E – MBMS data (being yes in the step 3), then refuse the unicast data of new incoming call, continue to utilize E – MBMS professional (step 9).If set for and preferentially utilize unicast service (being no in the step 3), then carry out processing and the unicast data reception ﹠ disposal (step 10) that stops E – MBMS data receiver.

In the step 4 of Figure 13, portable terminal receives unicast data in order to utilize simultaneously E – MBMS business and unicast service to the base station notice; In the step 5, the notice that the base station mobile terminal receive sends.The base station judges whether unicast data is issued portable terminal in step 6.Figure 15 illustrates the detailed condition of the judgement processing of step 6.Figure 15 illustrates the flow chart that judges whether unicast data is issued the portable terminal processing that utilizes E – MBMS business.In the step 1 of Figure 15, the base station receives unicast data in order to judge whether to utilize to reset, and judges the whether discontinuous transmission of E – MBMS business.Figure 16 and Figure 17 are the Resource Block key diagrams of the distribution of the Radio Resources such as the frequency of explanation when portable terminal is sent E – MBMS data, time.Among Figure 16, X direction represents frequency.The bandwidth of base station is the 20MHz of A to E.Y direction represents the time.When the received bandwidth of portable terminal is 10MHz, owing to can not receive simultaneously whole frequency bands to the 20MHz of the bandwidth A to E of base station, so communicate with the frequency range of 10MHz.According to following the example of of centre frequency, the position 1 among the figure (A-C frequency band, centre frequency F1), position 2 (C-D frequency band, centre frequency F2), position 3 (B-D frequency band, centre frequency F3) but be the frequency acceptance band of portable terminal.

In the example shown in Figure 16, distinguish E – MBMS content assignment to position 1 (that is, position 1 is the professional position of E – MBMS), and discontinuous transmission on the time shaft of the longitudinal axis.Namely, when carrying out the judgement of step 1 of Figure 15, as shown in figure 16, E – MBMS business is carried out discontinuous transmission and its discontinuous phase guarantee that portable terminal resets the required time in the situation of (hereinafter setting forth detailed condition), the base station is judged as and can changes centre frequency and change the UE position by utilizing to reset, and receives the unicast data that is distributed in diverse location.On the other hand, in the example shown in Figure 17, distinguish E – MBMS content assignment to position 1, and on the time shaft of the longitudinal axis, send continuously.That is, when sending continuously as shown in Figure 17 E – MBMS content, there is not the time of resetting to receive the unicast data that is distributed in diverse location.Thereby, when carrying out the judgement of step 1 of Figure 15, sending continuously in the situation of E – MBMS business on the time shaft, be judged as and can not receive in the mode of resetting the unicast data that is distributed in diverse location as shown in Figure 17.Moreover, for example E – MBMS uses A-B frequency band, clean culture to use in the situation of B-C frequency band, the B-C frequency band comprises the received bandwidth A-C (10MHz) of portable terminal, thus can receive simultaneously the unicast data that is distributed in frequency band B-C, no matter whether send E – MBMS data.

Also can consider relevant intention or the ability of whether carrying out the portable terminal of readjustment in step 1.The concrete Notification Method utilization of the intention of portable terminal is called the agreement of RRC (Radio Resource Control: Radio Resource is controlled), with layer 3 message informing base station.(Media Access Control: the media access control) signaling also can consider to be mapped to the method for physical channel from the portable terminal informing base station also to can be used as MAC.Again, the intention of portable terminal or ability can be used as terminal ability information and notify, also can be used as other parameter and notify.As concrete contents processing, during discontinuous transmission E – MBMS, confirm intention, the ability of portable terminal in the step 1.At this moment, in the situation of " do not do reset (maybe can not reset) ", be treated to noly in the step 1, proceed to step 2.In the situation of " doing to reset (maybe can reset) ", being treated in the step 1 is to proceed to step 4.Portable terminal was resetted with the short time (take Resource Block as unit), made the processing load of control part 15 and frequency conversion part 11 become large.Therefore, intention or the ability of the readjustment of consideration portable terminal are good.

In the step 1, owing to send continuously E – MBMS, be judged as and can not receive the unicast data (being no in the step 1) that is distributed in diverse location, then judging whether in step 2 can be to the professional position of E – MBMS schedule of apportionment multicast data.Figure 18 and Figure 19 are whether Resource Block is shown and illustrates can be to the key diagram of the professional position of E – MBMS schedule of apportionment multicast data.Figure 18 illustrates not to the key diagram of the professional position of E – MBMS schedule of apportionment multicast data, and Figure 19 is the key diagram that illustrates to the professional position of E – MBMS schedule of apportionment multicast data.Among Figure 18, the professional position of E – MBMS is the position 1 (10MHz) as the A-C frequency band of Figure 18, and A-B frequency band (being used as 5MHz among the figure represents) sends E – MBMS content continuously in the use location 1.And, distinguish the control data that B-C bandwidth assignment unicast service is used in position 1, the transmission of user data.

Among Figure 18, distinguish not have substantially idle Resource Block in the B-C frequency band, so in the frequency band of the professional position of E – MBMS, crowded by the down direction transmission of dispatching distribution.In this case, in the professional position of E – MBMS, can not distribute new unicast data.E – MBMS service digit is set up in the situation that does not have the Resource Block that distributes new unicast data like this, be judged as to be set up at E – MBMS service digit and can not distribute unicast data (being no in the step 2), and start or proceed the business that the user sets preferential reception in the professional and unicast service of E – MBMS in the step 7 of Figure 13.

Be judged as again when no processing shown in below can carrying out in the step 2 of Fig. 5.Even first processing in different positions (for example the situation of Figure 18, then between the D-E in the position 2), also to carry out E – MBMS professional.Like this, make position 1 and position 2 be the professional position of E – MBMS.Therefore, through and base station negotiate, portable terminal only once makes 1 readjustment that moves to position 2 from the position of UE position, just proceeds to step 3.Thus, portable terminal can one E – MBMS in the receiving position 2 professional, the unicast service in receiving position 2.The 2nd processes process and base station negotiate, and portable terminal only once moves to the readjustment of the position (in the situation of Figure 18, then being position 2 for example) that has the Resource Block that distributes new unicast data, just proceeds to step 3.Even many residential quarters, base station send, also E – MBMS data-mapping is sent to DL – SCH.The schedule information (frequency, time etc.) that will be mapped to the E – MBMS data of DL – SCH and clean culture number from the base station is according to notifying this portable terminal, thus portable terminal can one E – MBMS in the receiving position 2 professional, the unicast service in receiving position 2.Again, by from the base station to a plurality of portable terminals notice schedule informations (frequency, time etc.), but map to the E – MBMS data of DL – SCH on the portable terminal receiving position 2 of notified these information.Process and/or the 2nd process by adding the above-mentioned the 1st, in the step 2 of Figure 15, be judged as no situation and compare with the situation that proceeds to step 7 of Figure 13, advantage is arranged aspect the professional and unicast service of E – MBMS receiving simultaneously.

On the other hand.Among Figure 19, identical with Figure 18, the professional position of E – MBMS is the position 1 (10MHz) as the A-C frequency band, and A-B frequency band (being used as 5MHz among the figure represents) sends E – MBMS content continuously in the use location 1.And, distinguish the control data that B-C bandwidth assignment unicast service is used in position 1, the transmission of user data.Yet, among Figure 19, have idle Resource Block on the B-C frequency band, so can distribute new unicast data in the professional position of E – MBMS.Like this, exist in the situation of the Resource Block that distributes new unicast data in the professional position of E – MBMS, being judged as can be at the professional position schedule of apportionment multicast data (being yes in the step 2) of E – MBMS, and execution in step 3.Otherwise, be judged as in the step 2 of Figure 15 E – MBMS service digit be set up can not the situation of schedule of apportionment multicast data under, carry out the processing of the step 7 of Figure 13.The processing of the step 7 of Figure 13 is identical with the processing of the step 3 of Figure 13, so description thereof is omitted.

E – MBMS uses the A-B frequency band, and clean culture is used in the situation of B-C frequency band, even send continuously E – MBMS, also is limited to the received bandwidth A-C (10MHz) that includes portable terminal in, can receive E – MBMS data and unicast data, and two kinds of business all can be enjoyed.Thereby, send continuously E – MBMS (being no in the step 1) in step 1, and exist in the step 2 when distributing the Resource Block of new unicast data to the professional position of E – MBMS (being yes in the step 2), in step 3, the base station sends unicast data to the portable terminal that receives E – MBMS data, so dispatch, give new unicast data distributes resource blocks.In the case, do not reset to change the UE position, and can receive E – MBMS data and unicast data.Moreover the processing of the step 3 of Figure 15 is equivalent to the processing of the step 8 of Figure 13.

On the other hand, at the discontinuous transmission of the step 1 of Figure 15 E – MBMS, the UE position is changed, can receive unicast data (being yes in the step 1) thereby can be judged as, and the base station judges whether the actual portable terminal readjustment that makes in step 4.The base station utilize downlink quality information (Channel Quality Indicator) that portable terminal sends for example the frequency band of each Resource Block shown in Figure 16 (for example A-B, B-C, C-D, D-E) grasp frequency characteristic and quality.Thereby the base station can judge that to make portable terminal reset to receive unicast data unsatisfactory when for example frequency band C-D, D-E poor quality.When the position 2 of Figure 16 (position beyond the professional position of E – MBMS) is crowded, unicast data is dispatched to the professional position of E – MBMS, so portable terminal needn't be resetted again.Be judged as when portable terminal is resetted (being no in the step 4) processing of execution in step 2 in the step 4.On the other hand, be judged as when portable terminal is resetted (being yes in the step 4) processing of execution in step 6.

In the step 6, whether the base station is judged can the schedule of apportionment multicast data on the position, readjustment purpose place.In this step 6, also identical with step 2, judge whether to exist the Resource Block that distributes new unicast data, but idle opposite with reference to the Resource Block of E – MBMS position with step 2, step 6 is idle with reference to the Resource Block of position, readjustment purpose place, both are different on this aspect.And the mode of needed time of readjustment is made with reference to the free time of the Resource Block of position, readjustment purpose place in step 6 to consider portable terminal in the base station.

, portable terminal transforms to F2 (Figure 16) by the reference frequency that will be in the frequency conversion part 11 produces from F1 and carries out 1 readjustment that changes to position 2 from the position of UE position.Yet, when frequency conversion part 11 changes to F2 with reference frequency from F1, before the frequency F2 at stable generation readjustment purpose place, need the regular hour.Consider this portable terminal characteristic, the base station is made the mode of required time of readjustment and is dispatched to consider portable terminal.Particularly, want to make as shown in Figure 16 in the position 1 portable terminal that receives E – MBMS1 to reset position 2 when receiving unicast service, dispatch the base station, makes the clean culture 1 of new generation be assigned to a call duration time time departure RT (portable terminal is resetted the needed time) Resource Block from E – MBMS1.Carry out similarly the scheduling of clean culture 2, in order to it is assigned to from the Resource Block of the call duration time time departure RT of E – MBMS2.Can not guarantee in the situation of time RT that although the Resource Block of position, readjustment purpose place is free the base station can be judged as in position, readjustment purpose place can not the schedule of apportionment multicast data, also can on the deteriorated basis of estimated quality, be judged as and can distribute.Equally, when 2 readjustments were to position 1 from the position, portable terminal also spent the needed time of resetting.Therefore, the base station need to be made the mode of needed time of readjustment and dispatch to consider portable terminal.

In the step 6, be judged as on the position, readjustment purpose place (being yes in the step 6) can the schedule of apportionment multicast data time processing of execution in step 5 in the base station.Be judged as and divide timing (being no in the step 6), the processing of execution in step 2.In the step 5, the base station is in order to send unicast data to the portable terminal that receives the E – MBMS time, to the unicast data of the new generation position beyond in E – MBMS position with the mode of the asynchronism(-nization) of E – MBMS data to the unicast data distributes resource blocks.Carry out this dispatch deal by the base station, when portable terminal receives E – MBMS data in the professional position of E – MBMS, in the position of schedule of apportionment multicast data, one side is resetted when receiving unicast data, and one side is carried out the reception of E – MBMS data and unicast data in the different time.That is, portable terminal can both utilize E – MBMS business and unicast service.Moreover the processing of the step 5 of Figure 15 is equivalent to the processing of the step 8 of Figure 13.The processing sequence of Figure 15 also can be consistent with above-mentioned explanation.For example, at first carry out the processing of step 2, be judged as in step 2 and proceed to step 3 when being.Step 2 is judged as carries out the processing of step 1, step 4 and step 6 when no, and step 6 is judged as the processing of carrying out step 5 when being.Be judged as the processing of carrying out the step 7 of Figure 13 when no in step 1 or the step 4,6.

In the step 1 of Figure 13, portable terminal determines whether to receive and is used for the information (paging information, paging designator etc.) that (paging) processed in incoming call.Send the information that is used for the incoming call processing from the base station with following method, can receive the information that is used for the incoming call processing in order to receiving the portable terminal of E – MBMS data.Can not receive data that this time sends from the base station this can receive bandwidth less than the problem that the peculiar problem of this LTE of bandwidth of base station produces because of portable terminal in order to solve portable terminal on the position beyond the UE position, need the method.The Resource Block key diagram of Figure 20 and Figure 21 allocation of radio resources such as frequency and time when to be explanation to the portable terminal that receives E – MBMS data send to be used for information that incoming call processes.Among Figure 20, with the discontinuous transmission E of A-C frequency band (10MHz) – MBMS content.That is, E – MBMS service digit is set to position 1, and also 1 frequency band receives the portable terminal that is receiving E – MBMS data in the position simultaneously.Use each position to send from the base station and be used for the information that incoming call is processed, so that can be no matter (the UE position, position that portable terminal is selected; Select frequency band) can both receive.In the situation of Figure 20, use location 1 and position 2 and position 3 overlapping frequency band B-D are distributed in a plurality of Resource Block of the time discontinuous transmission different from E – MBMS.That is, use a plurality of Resource Block to send identical information.

Figure 21 is the key diagram when utilizing the A-B frequency band to send continuously E – MBMS content.Owing to send continuously E – MBMS content, can not send the information that is used for the incoming call processing with E – MBMS content transmitting time with staggering.Yet, to the E – MBMS content A-B frequency band in the distribution locations 1 (A-C) only, so can be used for the information that incoming call is processed to the B-C bandwidth assignment of position 1.Among Figure 21, identical with Figure 20, also use each position to send from the base station and be used for the information that incoming call is processed, so that can be no matter the position that portable terminal is selected receives (UE position).In the situation of Figure 21, use location 1 and position 2 and position 3 overlapping frequency band B-D are distributed in a plurality of Resource Block of the time discontinuous transmission different from E – MBMS.That is, use a plurality of Resource Block to send the identical incoming call process information that is used for.

The Resource Block key diagram of Figure 22 and Figure 23 allocation of radio resources such as frequency and time when to be explanation to the portable terminal that receives E – MBMS data send to be used for incoming call and to process the information (Paging message, Paging Indicator etc.) of (Paging).Among Figure 22, with the discontinuous transmission E of A-C frequency band (position 1) – MBMS content.And, to be used for information distribution that incoming call processes in the professional position of E – MBMS the Resource Block with the time discontinuous transmission different from E – MBMS.The Resource Block of the frequency band B-D that Figure 20 distribution locations 1 and position 2 and position 3 are overlapping, in order to can receive the position (frequency band is selected in the UE position) of selecting regardless of portable terminal for the information of incoming call processing, the difference of Figure 22 is the information that the position distribution is processed for incoming call to E – MBMS business.Thereby different from Figure 20, situation shown in Figure 21, will not be used for information distribution that incoming call processes to a plurality of Resource Block, help effective utilization of Radio Resource.Figure 23 is the key diagram that explanation sends the situation of E – MBMS content continuously.Because to the E – MBMS content A-B frequency band in the distribution locations 1 (A-C) only, thus the information distribution that will be used for the incoming call processing in the position 1 B-C frequency band.Because but the frequency acceptance band of portable terminal is 10MHz, can receive in the case no problemly.Figure 23 is also identical with Figure 22, be used for the message context that incoming call processes and have feature in that the professional position of E – MBMS is distributed, effectively utilize aspect the Radio Resource favourable.The professional position of E – MBMS distributed be used for the information that incoming call is processed, but can consider that also the scope on the frequency axis identical with the E – MBMS content (program) that receives of portable terminal in the professional position of E – MBMS often minute is used in the information that incoming call is processed.Therefore, reduce in the portable terminal reception ﹠ disposal the required frequency range of operation, so can think the advantage that obtains the processing load that reduces demodulation section 13, control part 15.

The Resource Block key diagram of Figure 24 and Figure 25 allocation of radio resources such as frequency and time when to be explanation to the portable terminal that receives E – MBMS data send to be used for information that incoming call processes.Among Figure 24, with the discontinuous transmission E of A-C frequency band (position 1) – MBMS content.And, will be used as for the information that incoming call is processed the part notice portable terminal of E – MBMS content.Particularly, will be mapped to MCH (transmission channel) for the information that the incoming call of the portable terminal that receives E – MBMS business is processed.Below, send an example using common signal channel as content, MCH is described.Perhaps, be positioned in MCCH (logic channel) or MTCH (logic channel).In other words, utilization carry out the media access control eNode B, carry out aGW that paging processes or the high-end network equipment and accept from the calculating of the E – MBMS content of portable terminal or login (ordering usefulness, activation) etc., at MCH but not PCH sends the information that incoming call is processed that is used for to the portable terminal that receives E – MBMS business.Perhaps, also can be at MCCH or MTCH but not PCCH send.At this moment, the information that incoming call processes that is used for of the portable terminal that do not receive E – MBMS business sent with PCH routinely like that.Like this, to be used as for the information that incoming call is processed the part of E – MBMS data, send to portable terminal with MCH, MCCH, MTCH, thereby the portable terminal that is receiving E – MBMS business carries out the reception of E – MBMS business datum, then also can receive the information of processing for incoming call.On this aspect, can simplify the paging reception ﹠ disposal in the portable terminal reception E – MBMS business procedure.Figure 25 is the key diagram when sending continuously E – MBMS content.To the E – MBMS content A-B frequency band in the distribution locations 1 (A-C) only, and send with MCH or MCCH, MTCH without PCH and to be used for the information that incoming call is processed.This point is identical with Figure 24.

The Resource Block key diagram of Figure 26 allocation of radio resources such as frequency and time when to be explanation to the portable terminal that receives E – MBMS data send to be used for information that incoming call processes.Among Figure 26, in the discontinuous transmission E of A-C frequency band (position 1) – MBMS content.And, to be equipped with the Resource Block of the time discontinuous transmission different with E – MBMS content in 2 minutes in the position different from the professional position of E – MBMS (Figure 26 is position 1) for the information of incoming call processing.As shown in figure 26, when being used for information that incoming call processes and being sent to portable terminal in different positions, portable terminal need to carry out resetting to from the professional position of E – MBMS and send the position that is used for the information that incoming call processes with E – MBMS data.When portable terminal is resetted, carry out switching to from centre frequency F1 (position 1) processing of F2, but after switching, before stablizing the frequency F2 of output switching, need the elapsed time (RT).Consider the time difference that this readjustment needs, after sending E – MBMS content, the time RT that sky is opened readjustment to be needed sends and is used for the information that incoming call is processed, by this way distributes resource blocks among Figure 26.

As system, the time of carrying out is adjusted, and makes PCH transmitting time and E – MBMS business transmitting time not overlapping, then in base station, aGW, the more high-end equipment, do not mind which portable terminal and whether receiving E – MBMS business, can receive PCH even receiving the portable terminal of E – MBMS business yet.Moreover, when the portable terminal that receives E – MBMS is sent the information that is used for incoming call, also can carry out above-mentioned adjustment to the PCH transmitting time, and the portable terminal that does not receive E – MBMS is sent in the mode that is positioned on the PCH that does not carry out the time adjustment.By such formation, do not need the PCH transmitting time with respect to the portable terminal that does not receive E – MBMS business is adjusted the time, so the degree of freedom increases.Yet, need to adjust the time with respect to the PCH of the portable terminal that receives E – MBMS business, in order to avoid overlapping with E – MBMS transmitting time.

So far, illustrated that with Figure 20～Figure 26 the base station sends the method that is used for the information that incoming call processes to portable terminal, but when not only sending PCH but also send SCH (Synchronized Channel: also available in the time of synchronizing channel).And, also can use when sending be used for sending control data that E – MBMS uses and MCCH (multicast control channel), the MTCH (multicast traffic channel) of user data.At this moment, consider in the mode that E – MBMS data is changed into MTCH, will change for the information that incoming call is processed MCCH into, then can use above-mentioned thought.Execution mode 3 has illustrated like that as mentioned the portable terminal that receives E – MBMS data (comprising control information) starts the step that unicast data receives, but the thought shown in the execution mode 3 also can be used for receiving the step of portable terminal startup reception E – MBMS data when (comprising control information) of unicast data.

Execution mode 4

Thereby exist the portable terminal that is receiving E – MBMS to move and to switch the situation of the switching of the residential quarter that communicates.Carry out receiving E – MBMS and also with MCH or MCCH, MTCH but not PCH send in the situation of the switching (direct-cut operation) when being used for information that incoming call processes, switch the purpose place and also must similarly send portable terminal with handover source and be used for the information that incoming call is processed.Therefore, in the communication system of LTE, directly communicate between the predetermined landing, so the base station notice of switching purpose is represented the information of " it is professional that the portable terminal that switches is receiving E – MBMS " from the base station of handover source.The identification of base stations of switching the purpose place moves the portable terminal that comes and is receiving E – MBMS business, then is not scheduled to and carries out overlappingly the PCH transmission with E – MBMS transmitting time.Perhaps, with MCH or MCCH, MTCH but not PCH will be sent to portable terminal for the information that incoming call is processed.Moreover, the transmitting time to the PCH (being used for the information that incoming call is processed) of the portable terminal that receives E – MBMS business is adjusted to when not overlapping with the transmitting time of E – MBMS data, also carry out and identical processing mentioned above.

Figure 27 is the flow chart that illustrates the hand-off process of the portable terminal that receives E – MBMS data.In the step 1, the portable terminal that receives E – MBMS content (calculates, logins (ordering usefulness, activation) and receive the E – MBMS content of wishing eNode B (1) notice as handover source base station.After receiving this notice, portable terminal is sent E – MBMS content.In the step 2, eNode B (1) with PCH not send the information of processing for incoming call with the overlapping mode of E – MBMS content transmitting time.In the step 3, decision makes portable terminal switch to as the eNode B (2) (purpose eNode B) that switches the purpose base station from the eNode B (1) (source eNode B) as handover source base station, then notifies " portable terminal that switches is utilizing E – MBMS business " at step 4eNode B (1) to eNode B (2).Finish hand-off process in the step 5, the used for mobile terminal PCH that then comes in step 6 pair movement at the notified eNode B (2) of step 4 is to send the information of processing for incoming call with the nonoverlapping mode of E – MBMS content transmitting time.

Moreover the processing of step 2 can be undertaken by base station or aGW either party, also can jointly carry out with eNode B.The information that needs when switching with the notice of the communication path between this base station, compare when notifying with the path of handover source base station-base-station control apparatus (RNC)-base station, switching purpose place with prior art (UTRAN system) is middle, having can be with the advantage of short time reception and registration.Yet, also can switch the purpose base station through the network notice from handover source base station.Again, portable terminal can again (calculate, login (ordering usefulness, activation) and receive E – MBMS content switching base station, purpose place notice.And, with MCH or MCCH, MTCH but not PCH sends when being used for information that incoming call processes also identical.

Again, when utilizing E – MBMS portable terminal professional and unicast service to switch, switching base station, purpose place also needs to determine whether portable terminal is carried out the transmission of E – MBMS data and unicast data.For example, in the situation about having, even handover source has enough abundant Radio Resource to sending E – MBMS data and unicast data, if it is not abundant to switch the Radio Resource at purpose place, also have to make E – MBMS business or unicast service to be given up.Figure 28 is the flow chart that illustrates the hand-off process of the portable terminal that receives E – MBMS data and unicast data.Among Figure 28, when portable terminal utilizes E – MBMS business and unicast service (step 1), determine hand-off process (step 2), then handover source base station eNode B (1) is receiving the information of E – MBMS data to switching base station, purpose place eNode B (2) notice expression portable terminal.Also can notify the message of " portable terminal receives E – MBMS business and unicast service just at the same time ".Whether notified eNode B (2) has the judgement that portable terminal is provided the Radio Resource of E – MBMS business and unicast service.With Figure 15 the detailed condition that this judges processing is described, so description thereof is omitted.

Figure 29 illustrates the base station of handover source and the key diagram of the Resource Block of the base station of switching the purpose place.(a) Resource Block of handover source base station is shown, the Resource Block that switches base station, purpose place (b) is shown.When Figure 29 (a) processing of step 2 in Figure 15 judges whether to utilize simultaneously the professional and unicast service of E – MBMS, be judged as and utilize simultaneously, thereby carry out in the position 1 frequency band to portable terminal transmission E – MBMS data and unicast data.On the other hand, Figure 29 (b) is judged as: almost do not have assignable Resource Block on the frequency band of position 1, can not utilize simultaneously E – MBMS business and unicast service.In the case, the user is specified preferential E – MBMS data or unicast data issue portable terminal.

Illustrated as mentioned, when utilizing E – MBMS portable terminal professional and unicast service to switch, before the switching, handover source base station is being utilized the message of E – MBMS business and unicast service to switching base station, purpose place notice portable terminal, thereby judges whether portable terminal is carried out the transmission of E – MBMS data and unicast data in switching base station, purpose place.Like this by before switching, judging whether to utilize simultaneously E – MBMS business and unicast service, can be in the effect of the residential quarter of switching purpose place base station selected more suitable (for example can utilize two kinds of business) no problemly thereby can obtain.
