Embodiment
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one
See also Fig. 1, it is the flow chart of an embodiment of the method for reseptance of a kind of system information in neighboring area of the present invention, and this method may further comprise the steps:
Step 101: before receiving system information in neighboring area, obtain the transmitting time of control signaling to be sent;
Wherein, the said transmitting time of obtaining control signaling to be sent comprises: be received in allocation of radio resources or the heavy assigning process controll block that network side sends; The piece that reads said controll block is first, from the first transmission Frame that obtains the Serving cell frame, to carry said control signaling of the piece of said controll block, confirms the transmitting time of control signaling according to the time slot that sends Frame.
For example; In the process of allocation of radio resources or heavily distribution; Network side is to the portable terminal transmit control block, carried the various control signalings that network side sends to portable terminal in this controll block, also carries the indication whether some send up signaling at the piece head of controll block; These indications are used in reference to and illustrate, and portable terminal can carry control signaling of giving network side to be sent in which the transmission Frame in the Serving cell frame.After portable terminal has obtained in the Serving cell frame, to be used to carry the transmission Frame of control signaling to be sent, just can obtain the transmitting time of each control signaling to be sent according to the time slot that sends the digital data frame.As; When the control signaling is up RRBP (Relative Reserved Block Period; When reserved block period) confirming signaling; When portable terminal obtains the Serving cell frame, carrying transmission Frame that up RRBP confirms signaling from the piece head of controll block is the 4th, 5,6 and 7 behind totally four Frames, just can finally confirm to send the transmitting time of a up RRBP affirmation signaling according to the time slot of these four Frames.
Need to prove that portable terminal sends to the control signaling of network side except being the up RRBP affirmation signaling, can also be other upstream control signalings, as, grouping mea-sure report or grouping system message status, present embodiment does not limit this.
What also need remark additionally is under the situation that remains in the controll block to be sent control signaling, to adopt the method for present embodiment to carry out the reception of system information in neighboring area.And, then can still adopt the mode of prior art for the situation of no control signaling to be sent in the controll block, that is, it is professional to hang up PS earlier, and receives system information in neighboring area.Present embodiment in the controll block during no control signaling to be sent the method for reseptance of system information in neighboring area do not limit.
Step 102: when the transmitting time of said control signaling takies the time of reception of said system information in neighboring area, preferentially send said control signaling;
Wherein, because portable terminal only has a radio-frequency devices, when portable terminal need receive system information in neighboring area and when network side sends control signaling, just produce temporal conflict in the same moment.For example; See also Fig. 2, it is for receiving the sketch map that system information in neighboring area conflicts with the time of origin that sends control signaling at synchronization, and is as shown in Figure 2; Because Serving cell and adjacent sub-district are asynchronous cell; Therefore, can not be synchronous between Serving cell frame and the adjacent sub-district frame, but exist the regular hour deviation.If portable terminal need receive system information in neighboring area by the 3rd, 4,5 and 6 four frame in the frame of adjacent sub-district; And also need be in the Serving cell frame the 4th, 5,6 and 7 totally four frames send control signaling, at this moment, the transmitting time of control signaling has taken the time of reception of system information in neighboring area; Promptly; Produced temporal conflict, then portable terminal sends and should control signaling, and is not to hang up the PS business.
What also need remark additionally here is; For situation shown in Figure 2; When if portable terminal need take any or any a plurality of Frame in the 3-7 frame scope in the Serving cell frame when sending control signaling; Temporal conflict is caused in the capital, and in such cases, portable terminal can send control signaling.
Step 103: when the transmitting time of said control signaling did not take the time of reception of said system information in neighboring area, it was professional to hang up packet-switched domain PS, and receives said system information in neighboring area.
For example, be example still, if portable terminal need receive system information in neighboring area by the 3rd, 4,5 and 6 four frame in the frame of adjacent sub-district with above-mentioned Fig. 2; And also need be in the Serving cell frame the 8th, 9,10 and 11 totally four frames send control signaling, at this moment, the transmitting time of control signaling does not take the time of reception of system information in neighboring area; Promptly; The not conflict on the generation time, then portable terminal is hung up the PS business, and receives system information in neighboring area.
What also need remark additionally here is; For situation shown in Figure 2; As long as when the control signaling that portable terminal sends does not take any or a plurality of arbitrarily said frame in the scope of the 3-7 frame in the Serving cell frame, just can not cause temporal conflict, in such cases; It is professional that portable terminal can be hung up packet-switched domain PS, and receive said system information in neighboring area.
Wherein, reduce the professional time of PS of hanging up in order to try one's best, said hang-up packet-switched domain PS business, and the reception system information in neighboring area comprises: receiving system message SI3 and SI4 include the indication information that whether receives SI7 and SI8 in said SI4; Read said SI4, when including the Indication message that receives SI7 and SI8 among the said SI4 of box lunch, hang up said PS business, and receive said SI7 and SI8.
Wherein, in GSM, GPRS or EDGE network, system information in neighboring area is mainly used at Idle state and transmitting state and calculates the C2 value of adjacent area, and according to C2 criterion assessment optimum subdistrict, so that portable terminal carries out district reselecting.System message SI3, SI4, SI7 and SI8 all comprise the need cell selecting parameter that is used to calculate the C2 value; But in the Typical Disposition of commercial network; Network side does not often dispose SI7 and SI8; The Frame that SI7 and SI8 are corresponding is often filled with 2B, also is invalid content even if portable terminal receives SI7 and SI8 and reads.When network side does not dispose SI7 and SI8, and portable terminal is still hung up PS when professional, will cause losing of data block, thereby influence the performance of number biography.Therefore; Can be with SI3 and SI4 minimal set as receiving system message; In SI4, comprise the indication information that whether receives SI7 and SI8, after portable terminal receives SI4 and reads SI4, if comprise among the SI4 when receiving the indication information of SI7 and SI8; Portable terminal is hung up the PS business again, and receives SI7 and SI8; If when not comprising the indication information that receives SI7 and SI8 among the SI4, portable terminal just need not receive SI7 and SI8, just needn't hang up the PS business yet, thereby promote several transfer performances of portable terminal.For example, can in the ACS territory of SI4, use a bit conduct whether to receive the indication information of SI7 and SI8, as, when this bit was 1, expression received SI7 and SI8, and when this bit was zero, expression did not receive SI7 and SI8.
Can find out by the foregoing description; The priority ratio that sends control signaling receives the priority of system information in neighboring area and wants high; When the transmitting time of control signaling when taking the time of reception of system information in neighboring area, promptly send control signaling when receiving between the system information in neighboring area conflicting on the life period, preferentially send control signaling; When the transmitting time of control signaling does not take the time of reception of system information in neighboring area; Promptly send control signaling with receive between the system information in neighboring area life period not on conflict the time, it is professional to hang up packet-switched domain PS, and receives said system information in neighboring area.Thereby the long-time disruption of data service of having avoided the receiving system message process to be brought has improved the professional efficient in PS territory.
