Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following detailed description, together with the accompanying drawings, is intended to illustrate exemplary embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced. The following detailed description includes specific details in order to provide a thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention may be practiced without these specific details.

In some instances, well-known structures and devices may be omitted or may be shown in block diagram form, centering on the core functionality of each structure and device, to avoid obscuring the concepts of the present invention. In the following description, the same components are denoted by the same reference numerals throughout the specification.

In the present invention, a user equipment (UE) may be fixed or mobile and various devices communicating with the BS to transmit and receive user data and / or various control information. The UE may be a terminal equipment, a mobile station, a mobile terminal, a user terminal, a subscriber station, a wireless device, a personal digital assistant (PDA) modem, a handheld device, and the like. Also, in the present invention, a base station (BS) is a fixed station that generally communicates with a UE and / or another BS, and exchanges various data and control information by communicating with the UE and another BS. do. The BS may be referred to as other terms such as an Advanced Base Station (ABS), a Node-B (NB), an Evolved NodeB (eNB), a Base Transceiver System (BTS), an Access Point and a Processing Server (PS).

The wireless network operator is moving the serving network to the fourth generation wireless network. The fourth generation wireless network is a Long Term Evolution (LTE) wireless network as defined by the Third Generation Partnership Project (3GPP). The LTE standard is also referred to as the EUTRA (Evolved Universal Terrestrial Radio Access) standard. The Code Division Multiple Access (CDMA) 2000 technology, such as the High Rate Packet Data (HRPD) technology defined by 3GPP2, has some difficulties in interoperating with the EUTRA technology. Thus, techniques that enable movement from HRPD to EUTRA involve evolved HRPD (evolved HRPD) techniques. The eHRPD radio access network may interoperate with the EUTRA radio access network. A mobile station supporting eHRPD technology may be handed off between an eHRPD access network and an EUTRA access network. In addition, a mobile station supporting eHRPD may perform cell reselection in an EUTRA or eHRPD access network. Other wireless protocols may use other types of modulation for wireless communications such as orthogonal frequency division multiplexing (OFDM), Gaussian minimum shift keying (GMSK), 8 phase-shift keying (8PSK), or CDMA modulation.

The mobile communication system maintained by the wireless network provider may not implement the eHRPD capability in all HRPD access networks. That is, while some HRPD networks are capable of eHRPD (this access network is referred to as an eHRPD access network), other HRPD access networks in the HRPD coverage area do not support the eHRPD capability (this access network is referred to as the HRPD access network For example, only HRPD cells overlapping the EUTRA coverage area or adjacent to the EUTRA coverage area will use the eHRPD access network.

Figure 1 illustrates an exemplary wireless communication network including an LTE network, an eHRPD access network, and a Wireless Local Area Network (WLAN). Although only one LTE network, one eHRPD access network, and one WLAN are shown in FIG. 1, there will typically be multiple LTE networks, multiple eHRPD networks, and multiple WLANs.

According to LTE technology, an LTE network includes an eNB B 102 (eNB) corresponding to a base station, and an eHRPD access network includes an eHRPD base station (HRPD BTS 118). The base station can perform one or more of the following tasks: radio resource management, mobility management for managing mobility of mobile stations, routing of traffic, and the like.

As shown in FIG. 1, in an LTE network, a UE 116 is wirelessly connected to an EUTRA access network via an eNodeB 102. The EURA access network is in turn connected to various elements, including the mobility management entity (MME) 104 and the serving gateway 106. The MME 104 is a control node for an LTE network. For example, the MME 104 performs idle mode mobile station tracking and paging procedures. In addition, the MME 104 has a function of selecting a serving gateway for initial entities and for a mobile station in handover. In addition, the MME 104 functions to authenticate the user of the mobile station.

Serving gateway 106 routes bearer data packets. In addition, the serving gateway 106 acts as a mobile anchor for the user side during handover between other access networks.

Also provided is an eHRPD access network in which the UE 128 is wirelessly connected. The eHRPD access network is connected to the HRPD serving gateway (HSGW) The HSGW 122 routes packet data traffic initiated at or at the mobile station. The HSGW 122 provides interworking of the mobile station to the EUTRA network. The interworking function includes support for mobility, policy control, billing, access authentication, roaming, and others. The HSGW 122 supports seamless inter-technology mobility transport between the EUTRA network and the eHRPD access network.

References to EUTRA, HRPD, and eHRPD standards are intended to refer to current standards as well as time evolving standards. Future standards evolving from EUTRA, HRPD, or eHRPD are expected to be referred to by other names. References to "EUTRA," "HRPD," or "eHRPD" are intended to cover the next evolving standard. Also, as described above, techniques or mechanisms may be applied to systems using other types of wireless protocols.

The WLAN may also be connected to the SPGW 106 and the 3GPP2 AAA server 124 via an enhanced Packet Data Gateway (ePDG) 132. The UE 134 may be connected to the ePDG 132 via a WiFi AP (Access Point) 130.

2 illustrates a method for updating location information of a user equipment (UE) in a handover between heterogeneous communication networks according to an embodiment of the present invention. In FIG. 2, the UE corresponds to a VoLTE terminal.

The UE 1 is connected to the LTE network via the EUTRN network (S1). The UE 1 determines handover (S2). In the embodiment according to FIG. 2, the UE 1 can handover from a LTE network corresponding to a 3GPP network to a Non-3GPP network, such as a WLAN or eHRPD network.

The UE 1 can establish a session by requesting a session with the ePCF 5 (S3). The 3GPP-AAA (Authentication Authorization Account) server 6 can request the HSS (Home Subscriber Server) 4 to register the location of the UE (S4-1). The location registration is performed through transmission of a Server-Assignment-Request (SAR) message from the 3GPP-AAA server 6 to the HSS 4, and the SAR message may include an international mobile subscriber identity (IMSI). In response to the location registration request, the HSS server 4 can transmit a Server-Assignment-Answer (SAA) message to the 3GPP-AAA server 6 (S4-2) (Access Point Name) information, and Packet Data Network Gateway (PGW) information. Then, the HSS server 4 can update the location information of the UE 1 or the subscriber of the UE to "AAA Registered" indicating that it is connected to the Non-3GPP network.

The UE 1 has completed the handover from the 3GPP network to the Non-3GPP network and is connected to the eHRPD network (S5), for example, until another handover or disconnection through the power- The connection state is maintained.

The UE 1 may decide to perform handover to the LTE network again (S6). The MME server 2 may transmit an ULR (Update Location Request) message to the HSS server 4 to request location registration request and subscriber information of the UE in step S7-1. The ULR message may include at least one of IMSI information, Radio Access Type (RAT) information, and ULR-flag information. In response to the location registration request, the HSS server 4 may transmit an Update Location Answer (ULA) message to the MME server 2 (S7-2). The ULA message may include at least one of Aggregate Maximum Bit Rate (AMBR) information and APN information. Then, the HSS server 4 can update the location information of the UE or the subscriber of the UE to "MME Granted" indicating that the UE is connected to the 3GPP network (i.e., LTE network).

The UE 1 has completed the handover from the Non-3GPP network to the 3GPP network and is connected to the LTE network (S8), for example, until another handover or disconnection through the power- The connection state is maintained.

The HSS server 4 can synchronize the location information of the UE or the subscriber in real time between the 3GPP network and the Non-3GPP network through the steps S3 to S8.

In addition, the first process (S2 to S5) and the second process (S6 to S8) may be performed while the order is changed.

FIG. 3 illustrates a method for updating location information of a user equipment (UE) in a handover between heterogeneous communication networks according to an embodiment of the present invention. Some of the embodiments related to Fig. 3 are the same as some of the embodiments related to Fig. Therefore, in order to avoid duplication of explanation, only the portion different from FIG. 2 will be described.

After updating the location information of the UE or the subscriber of the UE to "AAA Registered" by the handover of the UE 1, the HSS server 4 transmits the MSG-AS or SMSC (Short Message Service Center) 7 ) In step S15-1 (step S15-1). The PNR message may include RAT (Radio Access Type) information of the UE or a subscriber of the UE. Since the UE 1 has completed the handover from the LTE network to the eHRPD network (S11 to S14-2), the HSS server can transmit to the MSG-AS that the RAT information of the UE is eHRPD through the PNR message S15-1). In response, the MSG-AS 7 updates the RAT information of the UE and transmits a Push Notification Answer (PNA) message indicating that the update is successful (S15-2).

Also, when the UE 1 handover from the eHRPD network to the LTE network again, the HSS server 4 accesses the location information of the UE or the subscriber of the UE to the 3GPP network (i.e., LTE network) , The HSS server 4 can transmit a PNR (Push Notification Request) message to the MSG-AS or the Short Message Service Center (SMSC) 7 (S18-1) . The PNR message may include RAT (Radio Access Type) information of the UE or a subscriber of the UE. Since the UE 1 has completed the handover from the eHRPD network to the LTE network (S6 to S8 in FIG. 2), the HSS server can transmit to the MSG-AS that the RAT information of the UE is eHRPD through the PNR message (S18-1). In response to this, the MSG-AS 7 updates the RAT information of the UE and transmits a Push Notification Answer (PNA) message indicating that the update is successful (S18-2).

The HSS server 4 can synchronize the location information of the VoLTE terminal with the MSG-AS 7 in real time through the steps S14-1 to S18-2 shown in FIG. 3, Can be skipped.

FIG. 4 illustrates a method for providing incoming location information of a UE in a voice or SMS incoming according to an embodiment of the present invention. The embodiment of FIG. 4 relates to a CDMA 1x to VoLTE voice call. In order to receive a CDMA 1x to VoLTE voice call, the exchange can request an LCR (Location Request) message to the HSS server to request the UE or the subscriber of the UE to receive location information (S41).

S42: The HSS server can determine whether the called subscriber has not subscribed to the VoLTE service. If the called subscriber has not subscribed to the VoLTE service, the HSS server can provide CDMA 1x incoming information.

S43: If the called subscriber has not subscribed to the VoLTE service, the HSS server can determine whether the called subscriber has joined the VoLTE single service. When the called subscriber subscribes to the VoLTE single service, the HSS server can provide Media Gateway Control Function (MGCF) Temporary Local Directory Number (TLDN) information for IMS incoming.

S44: If the called subscriber has not subscribed to the VoLTE single service, it can determine whether the called subscriber has subscribed to the VoLTE supplementary service. If the called subscriber does not subscribe to the VoLTE supplementary service, the HSS server can provide the CDMA 1x incoming information.

S45: When the called subscriber subscribes to the VoLTE supplementary service, the HSS server can determine whether the VoLTE term flag (Term Flag) indicating whether the VoLTE incoming call service function is activated is ON. If the VoLTE termination service function of the called subscriber is OFF, the HSS server can provide CDMA 1x call termination information.

S46: If the VoLTE termination service function of the called subscriber is ON, the HSS server can determine whether the called subscriber (or its UE) is registered in the IMS network. If the called subscriber is not registered in the IMS network, the HSS server may provide CDMA 1x call information.

S47: If the called subscriber is registered in the IMS network, the HSS server can determine whether the called subscriber is registered in the eHRPD network. If the called subscriber is registered in the eHRPD network, the HSS server provides CDMA 1x call information.

S48: If the called subscriber is not registered in the eHRPD network, the HSS server may provide MGCF TLDN information for IMS incoming.

The HSS server can provide a CDMA 1x or VoLTE call based on Hybrid VoLTE subscriber location information for a CDMA 1x to VoLTE voice call through steps S42 to S48.

FIG. 5 illustrates a method for providing incoming location information of a UE in a voice or SMS incoming according to an embodiment of the present invention. The embodiment of FIG. 5 relates to a CDMA 1x to VoLTE SMS incoming. In order to receive the CDMA 1x to VoLTE SMS, the MSG-AS (or SMSC) may send an SMR (SMS Message Request) message to the HSS server to request the UE or the subscriber's destination location information of the UE (S51).

S52: The HSS server can determine whether the called subscriber has subscribed to the VoLTE Single service. If the called subscriber subscribes to the VoLTE single service, the HSS server can send an SMR ACK message to the MSG-AS for an IMS incoming call, and the SMR ACK message is "Access Deny Reason (ADR) = 0x15 (4G Deny) "

S53: If the called subscriber does not subscribe to the VoLTE single service, it can determine whether the called subscriber has subscribed to the VoLTE supplementary service. If it is determined that the called subscriber does not subscribe to the VoLTE single service, the called subscriber may be determined as a VoLTE hybrid subscriber or a hybrid VoLTE subscriber. That is, from S53, the called subscriber can be regarded as a hybrid subscriber.

If the called subscriber does not subscribe to the VoLTE supplementary service, the HSS server can provide the CDMA 1x incoming information.

S54: When the called subscriber subscribes to the VoLTE supplementary service, the HSS server can determine whether the VoLTE term flag (Term Flag) indicating whether the VoLTE termination service function is activated is ON. If the VoLTE termination service function of the called subscriber is OFF, the HSS server can provide CDMA 1x call termination information.

S55: If the VoLTE termination service function of the called subscriber is ON, the HSS server can determine whether the called subscriber has subscribed to the message service. If the called subscriber does not subscribe to the message service, the HSS server may provide CDMA 1x call information. The HSS server manages the message service as a supplementary service, and can selectively provide SMS over CDMA 1x and SMS over IMS.

S56: If the called subscriber subscribes to the message service, the HSS server can determine whether the called subscriber (or its UE) is registered in the IMS network. If the called subscriber is not registered in the IMS network, the HSS server may provide CDMA 1x call information.

S57: If the called subscriber is registered in the IMS network, the HSS server can determine whether the called subscriber is registered in the eHRPD network. If the called subscriber is registered in the eHRPD network, the HSS server provides CDMA 1x call information.

S58: If the called subscriber is not registered in the eHRPD network, the HSS server may send an SMR ACK message to the MSG-AS for IMS incoming, and the SMR ACK message is "Access Deny Reason (ADR) = 0x15 (4G Deny) ".

The HSS server can provide a CDMA 1x to VoLTE SMS reception based on Hybrid VoLTE subscriber location information through S52 to S58.

FIG. 6 illustrates a method for providing destination location information of a UE in a voice or SMS incoming according to an embodiment of the present invention.

The embodiment of FIG. 6 relates to VoLTE to VoLTE voice incoming. In order to receive VoLTE to VoLTE voice, a CSCF (Call Session Control Function) can request a location information request of a subscriber of the UE or UE by transmitting an LIR (Location Information Request) message to the HSS server (S61).

S62: The HSS server can determine whether the request is related to a voice call. The HSS server checks the value of media_type avp in the LIR message, and if it is not voice, it can process the corresponding service.

S63: If the request is related to a voice call, the HSS server can determine whether the called subscriber has subscribed to the VoLTE supplementary service. If the called subscriber does not subscribe to the VoLTE supplementary service, the HSS server may forward the MGCF SIP address to the CSCF for CDMA 1x incoming.

S64: When the called subscriber subscribes to the VoLTE supplementary service, the HSS server can determine whether the VoLTE term flag (Term Flag) indicating whether the VoLTE incoming call service function is activated is ON. If the VoLTE termination service function of the called subscriber is OFF, the HSS server can provide CDMA 1x call termination information.

S65: If the VoLTE termination service function of the called subscriber is ON, the HSS server can determine whether the called subscriber (or its UE) is registered in the IMS network. If the called subscriber is not registered in the IMS network, the HSS server may provide CDMA 1x call information.

S66: If the called subscriber is registered in the IMS network, the HSS server can determine whether the called subscriber is registered in the eHRPD network. If the called subscriber is registered in the eHRPD network, the HSS server can provide CDMA 1x call information.

S67: If the called subscriber is not registered in the eHRPD network, the HSS server can forward the called S-CSCF (Address of Serving-CSCF) for IMS incoming.

The HSS server can provide a CDMA 1x or VoLTE call based on the Hybrid VoLTE subscriber location information for VoLTE to VoLTE voice call through steps S62 to S67.
