Along with development of internet technology, existing SAE/LTE network and 2G/3G network are and deposit, and subrange therefore can occur and cover phenomenon on coverage.And owing to the speech business of portable terminal generally is based upon on the GERAN CS territory, after finishing voice communication, resident again to LTE or group user group (Closed SubscriberGroup that better data service can be provided for it according to carrier policy; Hereinafter to be referred as: CSG) on the network cell, therefore the core concept of various embodiments of the present invention is exactly that portable terminal is in the process of carrying out speech business release, the measurement report of having surveyed measured LTE and/or CSG network cell information is before reported Access Network, and before business release is finished, Access Network will send target cell information to portable terminal according to measurement report, portable terminal can be according to the adjacent cell frequency tabulation of the RAT in the target cell information and RAT precedence information and/or frequency precedence information, select suitable LTE or CSG sub-district, guarantee being redirected of sub-district, gravity treatment, carrying out smoothly of cell change or handoff procedure.
Fig. 1 is a measurement report report method embodiment flow chart of the present invention, and as shown in Figure 1, this method comprises:
Step 100 sends measurement report to Access Network in the session dispose procedure, and described measurement report comprises the measured value of long-term evolving network sub-district and/or CSG network cell;
Portable terminal is in the process of the enterprising lang sound business in GERAN CS territory, owing to do not need speech business is switched to LTE or CSG sub-district this moment.For reporting of the measurement report that reduces LTE of comprising unnecessary and/or CSG network cell, the measurement control mode that portable terminal adopts is for only LTE and/or CSG network cell being measured but do not report the measured value of LTE and/or CSG network cell, just say that also portable terminal will be measured LTE and/or CSG network cell in this process, obtain the measured value of LTE and/or CSG network cell, but do not report Access Network, can earlier this metrical information be stored on the portable terminal, need wait to give the correct time to send to Access Network again.
When business release is carried out in portable terminal end voice communication, in order to guarantee that Access Network obtains the measurement report of portable terminal information of adjacent cells and issues target cell information according to measurement report, portable terminal will send measurement report to Access Network in the session dispose procedure, surveyed the measured value of measured LTE sub-district and/or CSG sub-district before comprising in the described measurement report.Portable terminal will send measurement report to Access Network in the session dispose procedure can be divided into following several situation according to practical application, comprises in the session dispose procedure, and portable terminal sends measurement report to Access Network after Access Network sends the disconnection conversation message; Also can be in the session dispose procedure, send measurement report to Access Network behind the disconnection conversation message that portable terminal reception Access Network sends.More than two kinds of situations all be that portable terminal has been known in advance and will have been sent measurement report to Access Network in the session dispose procedure, institute's difference is the trigger condition difference, the former portable terminal is sending the disconnection conversation message when initiatively initiating professional dispose procedure after, initiatively sends measurement report immediately; The latter is that portable terminal triggers to Access Network transmission measurement report by receiving the disconnection conversation message when initiating professional dispose procedure by Access Network.Access Network can send the notification message that requires the mobile terminal reporting measurement report to portable terminal in advance, be in particular, Access Network can be before business discharges just portable terminal carrying out in the speech business process, by the notification message of dedicated channel to portable terminal transmission reporting measurement reports, portable terminal just sends the measurement report that Access Network needs according to above-mentioned triggering mode after receiving notification message.It can also be to send the notification message of reporting measurement reports by broadcast channel to portable terminal before speech business takes place that Access Network sends a notification message, and portable terminal is the measurement report that sends the Access Network needs according to above-mentioned triggering mode in professional dispose procedure equally after receiving notification message.Certainly the Access Network portable terminal of also can not giving advance notice sends measurement report to it, but in professional dispose procedure, send the request message of reporting measurement reports to portable terminal, require the mobile terminal reporting measurement report, after portable terminal receives this request message, send required measurement report to Access Network immediately.Measurement report can be by terminal by slow associated control channel (Slow Associated Control Channel; Be called for short: SACCH) or Fast Associated Control Channel (Fast Associated Control Channel; Be called for short: FACCH) report Access Network.
Step 101 receives the instruction message that is used for mobile management that described Access Network issues.
Access Network is after receiving the measurement report that portable terminal sends, measured value with each RAT cell information in the measurement report is a foundation, issue the instruction message that is used for mobile management, be specially Access Network and RAT priority and/or frequency priority be set according to carrier policy, and the target cell information sending that will comprise adjacent cell frequency information of each RAT and described precedence information gives portable terminal, and portable terminal can carry out redirecting cell, gravity treatment, cell change or switching according to each precedence information and the adjacent cell frequency Information Selection of RAT best cell.In the present embodiment, Access Network carries the instruction message that is used for mobile management in channel release message, be specifically as follows and in channel release message, increase the field that comprises LTE network cell frequency information and/or CSG network cell frequency information, comprise that also each above-mentioned precedence information is handed down to portable terminal, for portable terminal be redirected, gravity treatment, cell change or switching.
After portable terminal receives the target cell information that Access Network sends, according to comprising RAT adjacent cell frequency information and RAT precedence information and/or flow processs such as the frequency precedence information is redirected, gravity treatment, cell change or switching.Particularly, if comprise the frequency information of LTE sub-district and the frequency information of CSG sub-district in the target cell information, and comprise LTE precedence information and CSG precedence information, portable terminal knows that according to precedence information high promptly professional release of LTE priority ratio CSG priority will be linked on the LTE sub-district after finishing, thus portable terminal in the frequency information of LTE sub-district according to setting strategy or selecting a frequency to carry out being redirected of sub-district, gravity treatment, cell change or switching at random.If not only comprise the RAT precedence information of RAT sub-district in the target cell information, when also comprising the frequency precedence information of RAT sub-district, portable terminal selects in having the RAT information of adjacent cells of higher priority that the higher frequency respective cell of frequency priority is redirected, gravity treatment, cell change or switching.If when only comprising the frequency precedence information of RAT sub-district in the target cell information, then portable terminal select that the highest sub-district of frequency priority of all RAT sub-districts is redirected, gravity treatment, cell change or switching.
The measurement report report method that the embodiment of the invention provides may need to change to LTE or CSG network cell at the portable terminal that carries out speech business at the GERAN network when business discharges, and LTE and/or CSG sub-district are measured and do not reported following time of measurement control model of the measurement report of LTE and/or CSG sub-district when portable terminal only is in, because network side does not have the measurement report of relevant LTE and/or CSG sub-district, can't issue the phenomenon of LTE and/or CSG cell information, the measurement report that portable terminal will include LTE and/or CSG sub-district before business discharges has reported Access Network, Access Network is according to current measurement report, send target cell information to portable terminal, portable terminal is according to the adjacent cell frequency information of the RAT in the target cell information and RAT precedence information and/or frequency precedence information, select suitable LTE or CSG sub-district, guarantee being redirected of sub-district, gravity treatment, carrying out smoothly of cell change or handoff procedure improved service quality.
The measurement report report method that the foregoing description provided is under the situation that SAE/LTE network and 2G/3G network cover mutually, portable terminal finishes, and the solution of gravity treatment to can provide on the LTE of better data service or the CSG network cell for it time is provided after professional the release, because SAE/LTE network and 2G/3G network cover mutually, portable terminal is when carrying out adjacent cell measurement so, just can measure the signal message of LTE and/or CSG sub-district, and this metrical information is reported Access Network.When portable terminal does not have the LTE and/or the CSG network coverage of living inly, then do not comprise LTE and/or CSG cell information in the measurement report, Access Network can be that portable terminal selects the better adjacent sub-district of signal strength signal intensity to be redirected according to the measured value of the information of adjacent cells in the measurement report, not indicating mobile terminal be redirected, gravity treatment, cell change or switching, also reside on the former sub-district.
The embodiment of the invention provides a kind of target cell information sending method again, this method comprises that session discharges and finishes the forward direction portable terminal and issue target cell information, described target cell information comprises the adjacent cell frequency information of RAT, and RAT precedence information and/or frequency precedence information.
Portable terminal is in the process of carrying out speech business, because portable terminal only is in the measurement control mode that LTE and/or CSG cell measurement are not reported, Access Network does not have the measurement report of LTE and/or CSG neighbour sub-district in this business procedure.And finish precedent as after sending the disconnection conversation message to portable terminal or send the request message of reporting measurement reports to portable terminal after in session release, will receive the measurement report that comprises LTE and/or CSG sub-district that portable terminal sends immediately.After Access Network receives measurement report, measured value according to each adjacent sub-district, set the adjacent cell frequency information of each RAT and RAT precedence information and/or frequency precedence information according to strategy, form target cell information and send to portable terminal, specifically can be in the adjacent cell frequency tabulation of RAT, to comprise the adjacent cell frequency information of RAT and RAT precedence information and/or frequency precedence information, certainly RAT precedence information and/or frequency precedence information also can not be stored in the adjacent cell frequency tabulation of RAT but be stored in independently in the field, and perhaps other storage mode is enumerated herein no longer one by one.In order to guarantee that portable terminal finishes business and discharges back resident on LTE that data service preferably can be provided and/or CSG network cell, the LTE that Access Network comprises in will the measurement report according to mobile terminal reporting and/or the measured value of CSG network cell are formed the frequency information of LTE network cell and/or the frequency information of CSG network cell, and after according to predetermined policy RAT precedence information and/or frequency precedence information being provided with, be handed down to portable terminal, carry out mobility management process for portable terminal.After portable terminal receives target cell information, according to the adjacent cell frequency information of RAT and RAT precedence information and/or frequency precedence information, obtain Target cell and carry out redirecting cell, gravity treatment, cell change or switching, resident on this target adjacent section.
Because in professional dispose procedure, therefore Access Network will can send to portable terminal by channel release message with target cell information to portable terminal transmitting channel release message.Can change to LTE or CSG sub-district according to the Access Network requirement after making portable terminal finish professional release, in professional dispose procedure, network need issue LTE and/or CSG cell information to terminal.When network provides the optional cell information of mobile management for terminal, because network may provide the list of frequency of a plurality of RAT or a RAT for portable terminal, when so network issues the tabulation of adjacent cell frequency to portable terminal, send precedence information and/or the frequency precedence information of each RAT simultaneously to portable terminal, concrete grammar is shown in following method one or method two, in channel release message " Channel Release ", increase the list of frequency of LTE and/or CSG sub-district, and increase precedence information and/or the frequency precedence information of each RAT.Mobile terminal service carries out the sub-district gravity treatment after discharging and finishing if desired, and then adjacent cell frequency tabulation that issues according to network and RAT priority and/or frequency precedence information carry out the sub-district gravity treatment.
Method one: as shown in table 1 below, in " Channel Release " message, increase the list of frequency " E-UTRANFreqList " of E-UTRAN and/or the list of frequency " CSGFreqList " of CSG, in the list of frequency information of each RAT, increase RAT priority and/or the frequency precedence information of each RAT.
