Technical scheme of the present invention is described in detail below in conjunction with Fig. 6.
Fig. 6 shows the schematic flow diagram of method according to an embodiment of the invention to the terminal position management be in outside network coverage and paging.
As shown in Figure 6, first, network side server (as ProSe Application Server or ProSe Function) and far-end UE need just to be configured the need of location management and the granularity that realizes location management.
Wherein, this layoutprocedure can be pre-configured to be in far-end UE or in UICC, also can be by carrying out dynamic-configuration with the connection of network side server when far-end UE is positioned at the network coverage.Wherein, the granularity of location management can be cell-level, tracing area TA (tracking area) level, also can be the multiple macrocells bunch rank introduced for D2D business support.
Macrocell bunch rank can be undertaken dividing and configuring by Virtual network operator, and it divides needs configuration in the terminal.Divide the location management that macrocell bunch carries out far-end UE, the limitation of TA can be broken through, make the location management of far-end UE more flexible.Such as: the partitioning standards of macrocell bunch can be associated with the resource distribution of D2D business, can realize the D2D resource distribution change of UE and the synchronous generation of location updating like this, can reduce the interaction times of far-end UE and network side server.
Secondly, far-end UE is according to the location updating granularity configured, and carry out location updating with good conditionsi, basic principle is as follows:
If far-end UE and relaying UE have ongoing D2D and to communicate and far-end UE has the identification information (as SAE identification information) of relaying UE, then far-end UE can trigger relaying UE by location information report to ProSe Function;
If far-end UE does not get not ongoing D2D communication within the scope of relaying that the identification information of relaying UE or far-end UE be just in relaying UE, then far-end UE detects the E-CGI information that relaying UE forwards from network side, the granularity configured with self is compared: if the granularity of location management is cell-level, then positional information (namely current E-CGI) is reported to network side server (as ProSe Function) by far-end UE; If the granularity of location management is macrocell bunch rank, then distance terminal determines the macrocell bunch belonging to this E-CGI, and then reports the identification information of the macrocell belonging to this E-CGI bunch to network side server.
Wherein, when far-end UE reports position to network side server, new mark can be used to report positional information to ProSe Function.It should be noted that the location management that the present invention proposes is different based on the location management mechanism of MME from tradition, the maintenance entity of positional information is ProSeFunction; Far-end UE reports to the mark of ProSe Function, do not need picture S-TMSI (SAE Temporary Mobile Subscriber Identifier, the Temporary Mobile Subscriber Identity of UE in SAE, for identifying mobile terminal) the complete like that controlled entity such by MME distribute, and it can be that UE and ProSe Function is distributed by PC3 interface negotiation that far-end UE reports to the mark of ProSe Function; ProSe Function needs to possess mapping ability, and the mark that far-end UE is reported can map with the mark of 3GPP SAE such as S-TMSI.
Again, based on location management mechanism as above, the present invention can realize high efficiency paging mechanism: network side is when paging UE, first MME needs the positional information obtaining UE from ProSe Function, i.e. position enquiring, after ProSe Function carries out position feedback, MME determines whether to initiate paging and whether can in the paging of specific cell scope, to avoid the paging of the whole network broadcast type according to the information of the mark of relaying UE, macrocell or macrocell bunch.
Particularly, if ProSe Function has found the current mark of carrying out the relaying UE communicated of far-end UE, then the positional information of far-end UE can directly have been determined according to the positional information of relaying UE; Because existing network framework does not define direct interface between MME and ProSe Function, therefore, MME needs by other entity transfers to ProSe Function launch position query messages, or directly the new interface of definition realizes.
Technical scheme in the above embodiment of the present invention can realize the location management far-end UE be in outside the network coverage being carried out to certain frequency certain position granularity, solves the blindness paging of part covering scene lower network side when paging far-end UE and sends problem.
More than be described with reference to the accompanying drawings technical scheme of the present invention, the present invention proposes a kind of new Location Management Scheme being in the terminal outside the network coverage and paging scheme, can realize managing the positional information of the terminal be in outside the network coverage, and then can realize carrying out paging operation to far-end UE in specified scope, avoid and cause taking more Radio Resource at the whole network broadcast paging messages when needing paging far-end UE.
