Description

Terminal location management method, paging method, device and terminal

This application claims the priority of the Chinese Patent Application No. 201510272312.2, the invention titled "Location Management Method, Paging Method, Device and Terminal" of the terminal, which was submitted to the Chinese Patent Office on May 25, 2015. The citations are incorporated herein by reference.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a location management method for a terminal that is outside the network coverage, a location management device for a terminal that is outside the network coverage, and a paging for a terminal that is outside the network coverage. Method, a device for paging a terminal that is outside the network coverage, and a terminal.

Background technique

At the beginning of 3GPP Release 12, a discussion of partial coverage scenarios has been introduced, that is, two or more terminals that perform D2D (Device-to-Device) communication, some are located in the network coverage, and some are located outside the network coverage. A terminal located in the coverage of the network can be managed by the network side, and the terminal outside the network coverage has not defined how to perform location management. As shown in FIG. 1 , a partial coverage scenario is shown. In a partial coverage scenario, a base station establishes a connection with a SAE (System Architecture Evolution) or a core network (Core Network) through an S1 interface, and relays a UE (User Equipment, The user equipment may establish an RRC (Radio Resource Control) and a NAS (Non-access Stratum) signaling connection with the base station, and the remote UE may perform D2D communication with the relay UE.

Since the location management of the prior art mainly relies on the control signaling connection between the UE and the network side, such as a NAS connection, in a partial coverage scenario, the NAS connection between the remote UE and the network side may not exist, so the prior art does not Support for location management of out-of-coverage terminals. However, in a specific scenario, the network side still needs to know whether the remote UE exists, or needs to trigger a remote UE to initiate D2D communication by paging, such as starting a relay UE selection and connection process, and the existing solution. However, the location information of the remote UE cannot be managed. If the network side needs to page the remote UE through the relay UE, the result of lack of location management information is that the network needs to broadcast the paging message on the entire network, along with the number of terminals. The increasing amount of this will undoubtedly cause a huge waste of wireless resources.

Therefore, how to manage the location information of the terminal that is outside the network coverage is avoided, and the radio resource that is occupied by the paging message on the entire network when the remote UE needs to be paged is avoided, which is a technical problem to be solved.

The technical solution of the present invention will be described in detail below with reference to FIG.

6 shows a schematic flow diagram of a method of location management and paging of terminals outside of network coverage, in accordance with an embodiment of the present invention.

As shown in FIG. 6, first, the network side server (such as ProSe Application Server or ProSe Function) and the remote UE need to be configured on whether or not location management is required and the granularity of location management is implemented.

The configuration process may be pre-configured in the remote UE or in the UICC, or may be dynamically configured through a connection with the network side server when the remote UE is located in the network coverage. The granularity of the location management may be a cell level, a tracking area (TA), or a plurality of macro cell cluster levels introduced for D2D service support.

The macro cell cluster level can be divided and configured by the network operator, and the division needs to be configured in the terminal. The macro cell cluster is divided to perform location management of the remote UE, which can break through the limitation of the TA, and the location management of the remote UE is more flexible. For example, the division of the macro cell cluster may be related to the resource configuration of the D2D service, so that the synchronization of the D2D resource configuration change and the location update of the UE may occur, and the number of interactions between the remote UE and the network side server may be reduced.

Secondly, the remote UE performs conditional location update according to the configured location update granularity. The basic principles are as follows:

If the remote UE has ongoing D2D communication with the relay UE and the remote UE has the identification information of the relay UE (such as SAE identification information), the remote UE may trigger the relay UE to report the location information. Tell the ProSe Function;

If the remote UE does not obtain the identification information of the relay UE or the remote UE is only in the relay range of the relay UE and there is no ongoing D2D communication, the remote UE detects the E forwarded by the relay UE from the network side. -CGI information, compared with the granularity configured by itself: if the granularity of the location management is cell-level, the remote UE reports the location information (ie, the current E-CGI) to the network side server (such as ProSe Function); If the granularity of the location management is a macro cell cluster level, the remote terminal determines the macro cell cluster to which the E-CGI belongs, and reports the identification information of the macro cell cluster to which the E-CGI belongs to the network side server.

When the remote UE reports the location to the network side server, the location information can be reported to the ProSe Function by using the new identifier. It should be noted that the location management proposed by the present invention is different from the traditional MME-based location management mechanism. The maintenance entity of the location information is a ProSe Function; the identifier reported by the remote UE to the ProSe Function does not need to be like S-TMSI (SAE Temporary). The Mobile Subscriber Identifier, the temporary mobile subscriber identity of the UE in the SAE, is used to identify the mobile terminal, and is completely allocated by the control entity such as the MME. The identifier that the remote UE reports to the ProSe Function may be that the UE and the ProSe Function negotiate to allocate through the PC3 interface. Good; the ProSe Function needs to have mapping capability, so that the identifier reported by the remote UE can be mapped with the identifier of the 3GPP SAE, such as S-TMSI.

Again, based on the above location management mechanism, the present invention can implement a highly efficient paging mechanism: when the network side is paging the UE, the MME first needs to obtain the location information of the UE from the ProSe Function, that is, the location query, and the ProSe Function performs the position feedback. The MME determines whether to initiate paging and whether paging can be in a specific cell range according to the identifier of the relay UE, the macro cell or the macro cell cluster, to avoid full-network broadcast paging.

Specifically, if the ProSe Function finds the identifier of the relay UE that the remote UE is currently communicating with, the location information of the remote UE may be directly determined according to the location information of the relay UE; The direct interface between the ProSe Functions. Therefore, the MME initiates a location query message to the ProSe Function, which needs to be transited by other entities, or directly defined by a new interface.

The technical solution in the foregoing embodiment of the present invention can implement location management of a certain frequency of a certain location of a remote UE that is outside the network coverage, and solve the problem that the network side is at the remote end of the paging in the partial coverage scenario. Blind paging transmission problem when UE.

The terminal 7 can perform D2D communication with the relay terminal, and the relay terminal is within the coverage of the network.
