Embodiment
The embodiment of the present invention provides a kind of paging method and device, in order in comprising the network of HeNB or RN, guarantees the correct paging of MME to UE.
Centralized agents node described in the embodiment of the present invention is HeNB GW or DeNB.
When centralized agents node is HeNB GW, HeNB GW agency's communication equipment is HeNB;
When centralized agents node is DeNB, DeNB agency's communication equipment is RN.
Referring to Fig. 3, a kind of paging method that the embodiment of the present invention provides comprises step:
S101, MME obtain the acquiescence paging cycle of the communication equipment of centralized agents node-agent.
S102, MME, according to the acquiescence paging cycle of the communication equipment of centralized agents node-agent, determine the NAS paging cycle of UE under different base station.
Wherein, the NAS paging cycle of described definite UE under different base station, can realize by calculating the duration of the NAS paging timer of UE under different base station.
S103, MME, according to the NAS paging cycle of UE, initiate the paging to UE.
Preferably, step S101 comprises:
MME obtains the sign of communication equipment that centralized agents node reports and the corresponding relation list of the acquiescence paging cycle of this communication equipment;
MME, by described corresponding relation list, obtains the acquiescence paging cycle of the communication equipment of centralized agents node-agent.
Preferably, MME, in S1 interface process of establishing, or in eNB config update process, obtains the corresponding relation list that centralized agents node reports, and wherein, S1 interface is the interface between MME and centralized agents node.
Or step S101 comprises:
MME, by the upper layer NMS of the communication equipment of centralized agents node-agent, obtains the acquiescence paging cycle of the communication equipment of centralized agents node-agent.
Wherein, when centralized agents node is HeNB GW, when HeNB GW agency's communication equipment is HeNB, the upper layer NMS of HeNB is the management system HeMS of family's evolved base station; When centralized agents node is DeNB, when DeNB agency's communication equipment is RN, the upper layer NMS of RN is RN network management system (RN OAM).
Or step S101 comprises:
MME, in S1 interface process of establishing, or in eNB config update process, obtains the acquiescence paging cycle of the communication equipment that centralized agents node reports; Wherein, S1 interface is the interface between MME and centralized agents node; This gives tacit consent to paging cycle, the acquiescence paging cycle of the communication equipment that to be centralized agents node choose according to default principle, or be pre-configured in centralized agents node by operator.
That is to say, for the network that has centralized agents node, can complete the support to paging by following three kinds of methods.
Method one: centralized agents node reports acquiescence paging cycle list (default paging drx list) to MME.
Default paging drx list, i.e. the corresponding relation list of the acquiescence paging cycle of the sign of the communication equipment of centralized agents node-agent and this communication equipment.
For example, when setting up S1 interface or carrying out the renewal of S1 interface configuration between HeNB and HeNB GW, HeNB reports HeNB GW by the acquiescence paging cycle of oneself, HeNB GW receives after the value of acquiescence paging cycle (default paging drx) of different HeNB, it is carried out associated with the sign (ID) of HeNB, form a list, and this list is set up by S1 interface or eNB config update process sends to MME.MME receives after this list, according to the value of different acquiescence paging cycle (drx), calculate different NAS paging timers (paging timer), in the process of follow-up paging (paging), can carry out different operations according to different paging timer.The flow process that HeNB acquiescence paging cycle reports as shown in Figure 4.
For the network that comprises Relay, when setting up S1 interface or carrying out the renewal of S1 interface configuration between RN and DeNB, RN reports DeNB by the acquiescence paging cycle of oneself, DeNB receives after the value of acquiescence paging cycle (default paging drx) of different RN, by the sign of itself and RN, E-UTRAN Cell Global Identifier (E-CGI) information that is RN is carried out association, forms a list, and this list is set up by S1 interface or eNB config update process sends to MME.The flow process that corresponding acquiescence paging cycle reports can be referring to Fig. 4, and only the HeNB GW in Fig. 4 should change DeNB into, and HeNB should change RN into.
Method two: the default pagingdrx that informs the corresponding HeNB of MME or Relay by upper layer network system.
HeNB is in starting up's process, determine the information such as working frequency points, PCI, default paging drx of oneself, then, corresponding information is upgraded at HeMS place, HeMS obtains after the defaultpaging drx of this HeNB, can, by the value of the default paging drx of this HeNB by direct interface (if having direct interface) or indirect interface, send to MME.
Relay is in the process starting, if the default paging drx being configured for RN by RN network management system (RN OAM), by RN OAM by the default paging drx information reporting of this RN to MME.
Method three:
HeNB GW or DeNB are when carrying out S1 interface process of establishing or eNB config update process with MME, according to predefined principle (for example, choose maximum default paging drx or minimum default paging drx), select a default paging drx to report MME; Or, by the pre-configured acquiescence paging drx in HeNB GW (or DeNB) of operator, by HeNB GW (or DeNB), this acquiescence paging drx is reported to MME, the reference value that follow-up paging arranges as MME.
Provide several specific embodiments below.

Referring to Fig. 5, this paging flow process specifically comprises following four steps:
Step 1, HeNB1 and HeNB2 and HeNB GW between while setting up S1 interface, report respectively the default paging drx of oneself, HeNB GW and MME between report paging drx list when setting up S1 interface or being configured renewal, comprising E-CGI and the default paging drx of all HeNB of this HeNB GW subordinate community.
Step 2, UE adhering in tracing section updating request (TAU Request) message in request (Attach Request) or tracing section updating (TAU) process in adhering to (Attach) process, can carry UE specific paging drx, i.e. the paging cycle value of UE expectation.MME receives after UE specificpaging drx, according to the default paging drx of each HeNB receiving in this value and step 1, calculate UE paging timer relevant to NAS in each HeNB community, in order to control follow-up paging, such as, in the time interval that can this paging timer be set to continuous paging, before the paging response of not receiving UE, often this paging timer is overtime just carries out a paging.
Step 3, when MME need to carry out paging to UE, expectation paging cycle UE in step 1 being reported by paging message (UE specific paging drx) sends to eNB.ENB compares the acquiescence paging cycle of this paging cycle and self broadcast, gets wherein less value, as the paging drx of final this UE of paging, thereby according to this paging drx, calculates frame number and the subframe position that sends Paing message to this UE.Because MME is different to the NAS pagingtimer of the HeNB community under same HeNB GW, therefore to the paging between different HeNB communities, there is the regular hour poor, MME can be handed down to HeNB GW by paging message by this time difference information, by HeNB GW, according to the paging time of different HeNB communities, sends beep-page message.Therefore, MME sends to the paging message of HeNB GW need to comprise E-CGI and the corresponding paging interval time difference information of the HeNB community under this HeNB GW.
Step 4, UE are when monitoring paging, also use the smaller value in the acquiescence paging cycle of base station broadcast and the paging cycle of oneself expectation, calculate the frame number and the subframe position that receive Paing message, so just can guarantee that UE accurately listens to the beep-page message that oneself is issued in base station.
