In the embodiment of the present invention, after base station of the MME into the second collection of base stations sends paging request, when defaultWhen the page response that the interior base station not received in the second collection of base stations is sent, paging failure is determined；When within a preset timeWhen receiving the page response that the base station in the second collection of base stations is sent, determination is paged successfully.
In the embodiment of the present invention, when the delay requirement for needing to page terminal and page is lower than preset value, MME is firstFirst obtain the load data that terminal corresponds to the interface-free resources of base station in tracking area list；Then according to the first default load criterion andLoad data determines that collection of base stations belonging to base station, collection of base stations include first base station set and the second collection of base stations, the first baseSet expression base station operation of standing is in normal condition, and the second collection of base stations indicates that base station operation is in overload state；To firstBase station in collection of base stations sends paging request；When do not receive that base station in first base station set sends within a preset time seeksWhen exhaling response, determine that the base station into the second collection of base stations sends paging request or determines paging failure.In this way, when base stationWhen interface-free resources load is larger, base station of the MME first to work in normal condition sends paging request, if be in workThe base station calling success of normal condition will not need to send paging request in load condition to work again；If at workIt is unsuccessful in the base station calling of normal condition, will paging request no longer be sent in load condition to work.So in the present inventionPaging request only can be sent without sending paging request to the biggish base station of load to normal Base Station, avoid influencing interface-free resourcesThe existing business of the biggish base station of load.
Further embodiment of this invention provides a kind of method of network paging, MME is used for, as shown in Fig. 2, the method packetIt includes:
201, when the delay requirement for needing that the terminal is paged and paged is lower than preset value, MME obtains terminalThe load data of the interface-free resources of base station in corresponding tracking area list.
Wherein, terminal being stored in MME and corresponding to tracking area list, when needing to page the terminal, MME is obtained eventuallyHold the load data of the interface-free resources of base station in corresponding tracking area list.
It should be noted that MME can obtain the user signing contract information of terminal when terminal adheres to network from HSS, whenWhen needing to page the terminal, it is default to judge whether the delay requirement paged is lower than according to the user signing contract information of terminalValue.MME, which obtains terminal and corresponds to the mode of the load data of the interface-free resources of base station in tracking area list, to be acquisition in real time.
202, MME determines collection of base stations belonging to base station, collection of base stations according to the first default load criterion and load dataIncluding first base station set and the second collection of base stations.
Wherein, first base station set expression base station operation is in normal condition, and the second collection of base stations indicates at base station operationIn overload state.After the load data of MME acquisition base station compared with preset load criterion, base station can be divided into multipleDifferent collection of base stations, collection of base stations number can be two, or multiple.With first base station collection in the embodiment of the present inventionFor conjunction and the second collection of base stations two.
203, base station of the MME into first base station set sends paging request.
204, whether MME judgement receives the page response that any base station is replied in first base station set within a preset time,If not receiving the page response that any base station is replied in first base station set within a preset time, step 205 is executed；If pre-If receiving the page response that any base station is replied in first base station set in the time, step 214 is executed.
205, base station in the second collection of base stations is divided into high preferential by MME according to the second default load criterion and load dataGrade collection of base stations and low priority collection of base stations.
Wherein, high priority collection of base stations is the base station that load data is less than or equal to the second default load criterion, low excellentFirst grade collection of base stations is the base station that load data is greater than the second default load criterion.Since MME is not received within a preset timeThe page response that any base station is replied in first base station set, so MME also needs to carry out the base station in the second collection of base stationsIt pages, in the embodiment of the present invention, MME is before paging the base station in the second collection of base stations, according to the second default loadBase station in second collection of base stations is divided into high priority collection of base stations and low priority collection of base stations by standard and load data.
It should be noted that the number for the priority level that base station in the second collection of base stations divides is not limited in this stepIt is fixed.This step can also be performed simultaneously with step 202, i.e., in step 202 directly draw all base stations according to its load of machinery systemsIt is divided into the different multiple set of priority.In the embodiment of the present invention, the base station in the second collection of base stations is subjected to priority levelDivision, so that it is determined that the lesser base station of the load of machinery systems out, then first page the lesser base station of the load of machinery systems, if pagingIt is unsuccessful, then paging request no longer is sent to the big base station of the load of machinery systems, avoids influencing the biggish base station of interface-free resources loadExisting business.
206, MME sends paging request according to the base station into high priority collection of base stations.
207, the paging whether MME judgement receives that any base station is replied in high priority collection of base stations within a preset time is rungIt answers, if not receiving the page response that any base station is replied in high priority collection of base stations within a preset time, executes step208；If receiving the page response that any base station is replied in high priority collection of base stations within a preset time, step 214 is executed.
208, MME obtains the current loads data of base station interface-free resources in low priority collection of base stations.
209, whether MME judges the current loads data of base station in low priority collection of base stations all greater than the second preset negativeLotus standard, if the current loads data of base station execute not all greater than the second default load criterion in low priority collection of base stationsStep 210；If the current loads data of base station execute step all greater than the second default load criterion in low priority collection of base stationsRapid 213.
Wherein, MME judges base station in low priority collection of base stations according to the second default load criterion and current loads dataCurrent loads data whether all greater than the second default load criterion, if in low priority collection of base stations base station current loadsData then illustrate that the interface-free resources load of some base stations has reduced not all greater than the second default load criterion, right at this timeIt, which sends paging request, will not influence the existing business of base station.
210, MME determines that current loads data are no more than the base of the second default load criterion in low priority collection of base stationsIt stands.
211, MME current loads data into low priority collection of base stations are sent out no more than the base station of the second default load criterionSend paging request.
212, whether MME judgement receives in low priority collection of base stations current loads data no more than the within a preset timeThe page response that the base stations of two default load criterions is replied, if do not receive within a preset time in low priority collection of base stations whenPreload data execute step 213 no more than the page response that the base station of the second default load criterion is replied；If in preset timeThe paging that current loads data are replied no more than the base station of the second default load criterion in low priority collection of base stations is inside received to ringIt answers, executes step 214.
213, MME determines paging failure.
It should be noted that in step 209, when the current loads data of base station in low priority collection of base stations are all bigWhen the second default load criterion, MME may also wait for certain time (such as 30 minutes), then reacquire low priority base stationThe load data of base station interface-free resources at this time in set, then judge the interface-free resources at this time of base station in low priority collection of base stationsWhether load data, if the second default load criterion is still greater than, thens follow the steps all greater than the second default load criterion213；Otherwise, then step 210 can be executed.
214, MME determination is paged successfully.
In the embodiment of the present invention, when the delay requirement for needing to page terminal and page is lower than preset value, MME is firstFirst obtain the load data that terminal corresponds to the interface-free resources of base station in tracking area list；Then according to the first default load criterion andLoad data determines that collection of base stations belonging to base station, collection of base stations include first base station set and the second collection of base stations, the first baseSet expression base station operation of standing is in normal condition, and the second collection of base stations indicates that base station operation is in overload state；To firstBase station in collection of base stations sends paging request；When do not receive that base station in first base station set sends within a preset time seeksWhen exhaling response, determine that the base station into the second collection of base stations sends paging request or determines paging failure.In this way, when base stationWhen interface-free resources load is larger, base station of the MME first to work in normal condition sends paging request, if be in workThe base station calling success of normal condition will not need to send paging request in load condition to work again；If at workIt is unsuccessful in the base station calling of normal condition, will paging request no longer be sent in load condition to work.So in the present inventionPaging request only can be sent without sending paging request to the biggish base station of load to normal Base Station, avoid influencing interface-free resourcesThe existing business of the biggish base station of load.
