Description

  The present invention relates to a service application of an evolved packet system (EPS) in communication technology, and in particular, in a case where a user equipment (UE: User Equipment) accesses a closed subscriber group (CSG) area in EPS. The present invention relates to a mobile service recommendation method based on detection of a CSG area location event and a corresponding system.

  The Evolved Packet System (EPS) is a network architecture based on the LTE (Long Term Evolution) system developed by 3GPP. As shown in FIG. 1, the EPS architecture related to location service includes E-UTRAN (Evolved Universal Terrestrial Radio Access Network) and Evolved Packet Core (EPC).

  As shown in FIG. 1, the EPC related to the location service includes a mobility management entity (MME), an E-SMLC (Evolved-Serving Mobile Location Center), and a gateway mobile location center (GMLC: Gateway Mobile). A location center (SGW), a serving gateway (SGW), a packet data network gateway (PGW), and a home subscriber server (HSS).

  Here, MME is a control plane network entity of EPS, mainly mobility management of user equipment (UE: User Equipment), session management, processing and security encryption function of non-access layer signaling, lawful interception of signaling, It is responsible for the PGW / SGW / MME selection function, the transmission of alarm messages, the selection of a suitable base station (eNB: Evolved NodeB) or home base station (HeNB: Home Evolved NodeB) for alarm messages, and the like. Specifically, the MME is connected to the eNB / HeNB via the S1-MME interface.

  E-SMLC is a positioning center that calculates UE position and transmits auxiliary data, mainly interacts with UE and / or eNB to complete positioning calculation, transmits auxiliary data to UE, and coordinates the whole positioning It is responsible for executing and scheduling resources necessary for positioning. The E-SMLC is connected to the MME via the SLs interface.

  The GMLC is a gateway between the location service client (Client) and the mobile network, and mainly registers and authenticates location services, sends positioning requests to the MME, receives final positioning results from the MME, and between multiple GMLCs Responsible for communication. The GMLC is connected to the MME via the SLg interface.

  SGW is the user plane network entity of EPS, mobility anchor for switching between eNB / HeNB, mobility anchor for switching between 3GPP systems, packet routing and forwarding function, lawful intercept of user plane, Functions such as a cache for downlink data of the idle UE and an uplink / downlink charge for home routing data during roaming are executed. The SGW is connected to the eNB / HeNB via the S1-U interface.

  The PGW is a gateway that connects an EPS network and a packet data network (for example, the Internet), and mainly processes functions such as threshold control of uplink and downlink data streams, UE IP address assignment, and lawful intercept.

  The HSS includes user subscription data, eg, user identifier, mobile phone number, quality of service (QoS) parameters for each type of subscription, addresses of MMEs and PGWs that provide services to the user, etc. save.

  In EPS, a general operation flow of a location service based on a location event is as shown in FIG.

  In step 201, the client (Client) initiates a location service request for requesting acquisition of the UE location from the network side to the GMLC. The request message includes a location area definition, a location event definition, a request valid time limit, and the like.

  In step 202, a request for providing a user location is transmitted from the GMLC to the MME, and the request message includes a location area definition, a location event definition, an expiration date of the request, and the like. Here, the location area definition in step 202 has been converted from the definition already described in geographic shape in the location service request in step 201 to a definition described in country code, network code, cell code, and the like.

  In step 203, paging, authentication and notification are performed between the MME and the UE so that the MME verifies the UE's location event support capability in the following (see steps 204 and 205).

  In step 204, the MME transmits a location event call to the cell location-determined UE, and the location message definition is attached to the call message, specifically, location event content, location event report frequency, location event expiration date, etc. Is included.

  In step 205, if the location event call of step 204 is correctly received by the UE and the UE supports the location event definition attached to the call message, the UE returns a location event call confirmation to the MME and Start monitoring event occurrence.

  In step 206, after receiving the UE location event call confirmation, the MME returns a confirmation of user location provision to the GMLC, which corresponds to step 202.

  In step 207, after receiving the confirmation of the user location provision, the GMLC returns a location service response for notifying whether the location service request sent in step 201 has been accepted successfully to the client.

  In step 208, the occurrence of a location event was monitored by the UE.

  In step 209, the UE sends a location event report to the MME after establishing a connection with the circuit domain or group domain of the MME. According to the definition of the location event report, if it is a single location event report, after transmitting the report, the UE ends monitoring the occurrence of the location event, and if it is a multiple location event report, the UE transmits the report. Later, the UE continues to monitor the location event occurrence, but the time interval between the two reports does not exceed the minimum interval time.

  In step 210, the MME sends a user location report to instruct the GMLC to generate a location event.

  In step 211, the GMLC correctly receives the user location report and then returns a user location report confirmation to the MME, which corresponds to step 210. At this time, the MME can record the billing information.

  In step 212, the GMLC returns a location service response to the client, which corresponds to step 201. At this time, the GMLC can record the billing information.

  A typical application of such location services in the prior art is that one mobile user subscribes to a location event reminder service for another mobile user. For example, if a parent subscribes to a reminder service, the location event is reported to the parents when the child enters the school area location every day.

  As the home base station is located in the home area, the mobile user establishes contact with the CSG area covered by the closed home base station. The store also has an open or semi-open home base station in the store CSG area. There is no corresponding solution in the prior art on how to use the communication between mobile users and these CSG areas to trigger recommendations for relevant mobile services.

  The present invention has been made in view of the above, and it is a main object of the present invention to provide a mobile service recommendation method and system based on the detection of a CSG area location event, and a mobile service recommendation for connecting to a network server (for example, the Internet).

  In order to further clarify the object, solution, and merit of the present invention, the present invention will be described in more detail below with reference to the drawings and embodiments.

  In LTE deployment, the HeNB is deployed in a private home by the operator or user and is a non-public resource for use by mobile users. At this time, the business operator or user can receive the discount information provided from the store near the home and play an online game with other friend users who enter the home CSG area. We want to recommend mobile services that meet specific needs to mobile users entering the area.

  In addition, the HeNB is placed in a public place such as a department store, a supermarket, or a store by a business operator or a store, and is used as a public resource for use by users who enter these public places. At this time, for example, the business operator or the store provides on-site discount information to a user who enters the store CSG area, provides delivery service information to a user who leaves the store CSG area, and limits the period for users who enter the nearby home CSG area. It is hoped to provide mobile services that meet specific needs to mobile users that enter the store CSG area and mobile users that enter a nearby home CSG area, such as providing discount information.

  To meet the above needs, embodiments of the present invention provide a mobile service recommendation system and method based on sensing CSG area location events, via one or more facilities in EPC, When the one or more UEs are associated with the home or merchant CSG area using the interaction between them, the network can sense a location event to recommend related mobile services to the UE.

  Based on the mobile service recommendation system shown in FIG. 3, FIG. 4 shows a mobile service push flow according to an embodiment of the present invention, which includes the following steps.

  In step 401, the first UE initiates a mobile service recommendation request to the mobile service recommendation server. The request message is used to request the network server to perform mobile service recommendation based on the CSG area location event, and one or more second UE identifiers, CSG customization information, service type definition, mobile service recommendation definition , And the expiration date of the request.

  Here, the first UE refers to a UE that initiates a mobile service recommendation request, and the second UE identifier attached to the mobile service recommendation request may include the first UE identifier or other UE identifiers. The other UE identifier may be a UE identifier used by another user (for example, a friend user) related to the user of the first UE. As should be described, in the flow shown in FIG. 4, the second UE identifier attached to the mobile service recommendation request includes only the first UE identifier. Accordingly, in steps 406 to 408, the MME needs to perform location event call confirmation with only the first UE.

  The CSG customization information may be a store name designated by the first UE, and the CSG customization information may not be a CSG identifier that can be identified in the communication network. Similarly, the first UE may specify a mobile service that the network wants to recommend from the network via the mobile service recommendation definition.

  In one specific implementation of the present invention, the first UE sends the request message to the MME, and when the MME determines that the request message is a mobile service recommendation request based on the service type definition, one of the requests is sent. Alternatively, a plurality of second UE identifiers are acquired and a request message is transmitted to the mobile service recommendation server.

  In step 402, the mobile service recommendation server initiates a location service request. The request message is used to request acquisition of related information from the network side to the GMLC, and includes a CSG area location definition, a location event definition, a request expiration time limit, and the like.

  Specifically, the mobile service recommendation server may determine, based on one or more second UE identifiers, a CSG area associated with these second UEs, eg, a home CSG area to which each second UE belongs, or each current second UE. The store CSG area where is located is determined.

  In step 403, the GMLC sends a user and CSG area location request to the MME. The request message includes user and CSG area location definition, location event definition, request valid time limit, and the like.

  In step 404, the CSG area position is queried. Specifically, the MME queries the location information of the related CSG area to the CSG list management server.

  In step 405, the CSG area position is returned. Specifically, the CSG list management server returns an inquiry result of the CSG area position to the MME. In general, the inquiry result may be the geolocation information of the verified location of the home base station that the home base station provided to the operator at the first startup.

  In step 406, paging, authentication and notification are performed between the MME and the first UE. In this step, the MME needs to verify whether the first UE has the ability to support the CSG area location event.

  In step 407, the MME sends a location event call to the first UE whose cell location has been determined. The CSG area location event definition is attached to the call message, and specifically includes CSG area location event content, CSG area location event reporting frequency, CSG area location event expiration date, and the like.

  In step 408, if the location event call of step 407 is correctly received by the first UE and the first UE supports the location event definition attached to the call message, the first UE returns a location event call confirmation to the MME. And start monitoring the occurrence of the CSG area position event.

  In step 409, after all CSG area location return of the CSG list management server and UE location event call confirmation are received by the MME, the MME returns a confirmation of the provision of the user and CSG area location to the GMLC. It corresponds to.

  In step 410, the GMLC starts CSG area location event registration with the CSG area location event management server after receiving confirmation of user location provision. The registration message includes a user and CSG area position definition, a position event definition, and a position event valid time limit.

  In step 411, the CSG area location event management server returns a CSG area location event registration confirmation to the GMLC after receiving the CSG area location event registration.

  In step 412, the GMLC returns a location service response to notify the mobile service recommendation server whether the location service request initiated in step 402 has been successfully accepted.

  In step 413, the mobile service recommendation server returns a mobile service recommendation confirmation to notify the first UE whether the mobile service recommendation request started in step 401 has been successfully accepted.

  After step 413, the flow may proceed to steps 414 to 419, or the flow may proceed to steps 414 'to 419'. Here, Steps 414 to 419 are scenes in which an event occurs in which the first UE enters the home CSG area position, and Steps 414 ′ to 419 ′ cause the first UE to enter the shop CSG area position or the shop CSG area position. This is a scene where an event to leave

  The following are steps 414-419.

  In step 414, the occurrence of a CSG area location event was monitored by the first UE. In the scene, the CSG area location event is that the UE accesses the home HeNB (home HeNB) or the UE enters the home CSG area. Here, the home CSG area is an area covered by one or a plurality of home HeNBs.

  It should be explained that the UE entering the home CSG area means that the UE can detect the identifier of the home HeNB, but the UE and the home HeNB must always establish a connection. That is, it is not always necessary for the UE to access the home HeNB.

  In step 415, the first UE sends a location event report to the MME after establishing a connection with the circuit domain or group domain of the MME. According to the definition of the location event report, if it is a single location event report, after transmitting the report, the UE ends monitoring the occurrence of the location event, and if it is a multiple location event report, the UE transmits the report. Later, the UE continues to monitor the location event occurrence, but the time interval between the two reports does not exceed the minimum interval time.

  At step 416, the MME sends a user location report to instruct the GMLC to generate a CSG area location event.

  In step 417, the GMLC correctly receives the user location report and then returns a user location report confirmation to the MME, which corresponds to step 416. At this time, the MME can record the billing information.

  In step 418, the GMLC returns a location service response to the mobile service recommendation server, corresponding to step 402. At this time, the GMLC can record the billing information.

  In step 419, the mobile service recommendation server initiates a mobile service push to the first UE based on information such as the service type definition requested by the first UE in step 401, the mobile service recommendation definition, and the request expiration time, For example, discount information provided from a store near the home is provided.

  The following are steps 414'-419 '.

  In step 414 ', the occurrence of a CSG area location event was monitored by the first UE. In the scene, the CSG area location event is when the UE accesses or disconnects from the store HeNB, or the UE enters or leaves the store CSG area. Here, the store CSG area is an area covered by one or more stores HeNB.

  In step 415 ', the first UE sends a location event report to the MME after establishing a connection with the circuit domain or group domain of the MME. According to the definition of the location event report, if it is a single location event report, after transmitting the report, the UE ends monitoring the occurrence of the location event, and if it is a multiple location event report, the UE transmits the report. Later, the UE continues to monitor the location event occurrence, but the time interval between the two reports does not exceed the minimum interval time.

  In step 416 ', the MME sends a user location report to instruct the GMLC to generate a CSG area location event.

  In step 417 ', the GMLC correctly receives the user location report and then returns a user location report confirmation to the MME, corresponding to step 416'. At this time, the MME can record the billing information.

  In step 418 ', the GMLC returns a location service response to the mobile service recommendation server, corresponding to step 402. At this time, the GMLC can record the billing information.

  In step 419 ′, the mobile service recommendation server initiates a mobile service push to the first UE based on information such as the service type definition requested by the first UE in step 401, the mobile service recommendation definition, and the expiration date of the request. For example, providing site discount information to a user entering the store CSG area, providing delivery service information to a user leaving the store CSG area, and the like.

  As can be seen, the mobile service recommendation server can recommend different mobile services according to different location events.

  As shown in FIG. 5, in another embodiment of the present invention, a mobile service recommendation flow based on sensing a CSG area location event includes the following steps.

  Step 501 is initiated by the UE 1 to initiate a mobile service recommendation request from the user to the mobile service recommendation server. The request message is a request for mobile service recommendation based on a CSG area location event, and includes a UE1 identifier, a CSG1 identifier associated with UE1, a UE2 identifier, a CSG2 identifier associated with UE2, a service type definition, a mobile service recommendation definition, and a request Includes expiration date. Here, the CSG1 area is covered by HeNB1, and the CSG2 area is covered by HeNB2.

  In a specific implementation of the present invention, HeNB1 is the home HeNB of UE1, and HeNB2 is the home HeNB of UE2.

  In step 502, location service billing is initiated by the mobile service recommendation server, and the network side requests GMLC to obtain relevant information. The request message includes a CSG area location definition, a location event definition, a request valid time limit, and the like.

  In step 503, the user and CSG area location are provided, and the GMLC sends a user and CSG area location request to the MME. The request message includes user and CSG area location definition, location event definition, request valid time limit, and the like.

  Step 504 is a CSG area location query, and the MME queries the location information of the related CSG area to the CSG list management server.

  Step 505 is a CSG area position reply, and the CSG list management server returns an inquiry result of the CSG area position to the MME. For example, the verified home provided by the home base station to the operator at the first start-up. This is geolocation information where the base station is located.

  Step 506 is paging, authentication and notification between the MME and UE1, and the MME verifies the CSG area location event support capability of UE1.

  In step 507, the MME transmits a location event call to the UE 1 that has determined the cell location, and the call message is attached with the CSG area location event definition. Includes expiration date.

  In step 508, if the location event call of step 507 is correctly received by UE1 and UE1 supports the location event definition in the call message, UE1 returns a location event call confirmation to the MME and the CSG area location event. Start monitoring the occurrence.

  Step 509 is paging, authentication and notification between the MME and UE2, and the MME verifies the CSG area location event support capability of UE2.

  In step 510, the MME transmits a location event call to the UE 2 that has determined the cell location, and the CSG area location event definition is attached to the call message, and the CSG area location event content, CSG area location event report frequency, CSG area location event Includes expiration date.

  In step 511, if the location event call of step 507 is correctly received by UE2 and UE2 supports the location event definition attached to the call message, UE2 returns a location event call confirmation to the MME and CSG Start monitoring the occurrence of area location events.

  As a matter of explanation, UE1 cannot acquire the related information of HeNB2 unless UE2 returns a position event call confirmation. Correspondingly, the scene from step 517 'to step 522' does not occur.

  In step 512, after receiving the CSG area location reply of the CSG list management server and the location event call confirmation message of UE1 and UE2, the MME returns a confirmation of the provision of the user and the CSG area location to GMLC, and the step returns to step 503. It corresponds.

  In step 513, the GMLC initiates CSG area location event registration with the CSG area location event management server after receiving confirmation of the user and CSG area location provision. The registration message includes a user and CSG area position definition, a position event definition, and a position event valid time limit.

  In step 514, the CSG area location event management server returns a CSG area location event registration confirmation to the GMLC after receiving the CSG area location event registration.

  In step 515, the GMLC returns a location service response to notify the mobile service recommendation server whether the location service request in step 502 has been successfully accepted.

  In step 516a, the mobile service recommendation server returns a mobile service recommendation confirmation to notify UE1 whether or not the mobile service recommendation request in step 501 has been successfully accepted.

  In step 516b, the mobile service recommendation server returns a mobile service recommendation confirmation to notify UE2 whether or not the mobile service recommendation request initiated by UE1 has been successfully accepted.

  Steps 517 to 522 are scenes in which an event occurs in which UE2 enters the CSG area position.

  In step 517, the occurrence of a CSG area location event was monitored by UE2, for example, UE2 accessed the HeNB2 connection or the HeNB2 identifier was detected by UE2.

  As an explanation, in one specific implementation of the present invention, the mobile service recommendation request was initiated by UE1, and the relevant information of HeNB1 was not acquired by UE2, so the identifier of HeNB1 was detected by UE2. Does not consider the occurrence of a CSG area location event to be monitored by UE2.

  In step 518, UE2 sends a location event report to the MME after establishing a connection with the circuit domain or group domain of the MME. According to the definition of the location event report, if it is a single location event report, after transmitting the report, UE2 finishes monitoring the occurrence of the location event. Later, UE2 continues to monitor the location event occurrence, but the time interval between the two reports does not exceed the minimum interval time.

  In step 519, the MME sends a user location report to the GMLC to indicate the occurrence of a CSG area location event.

  In step 520, after the GMLC has correctly received the user location report, it returns a user location report confirmation to the MME, corresponding to step 519. At this time, the MME can record the billing information.

  In step 521, the GMLC returns a location service response to the mobile service recommendation server, corresponding to step 502. At this time, the GMLC can record the billing information.

  In step 522, the mobile service recommendation server initiates a mobile service push to UE1 based on information such as the service type definition requested by UE1 in step 501, the mobile service recommendation definition, the expiration date of the request, eg, UE2 The UE1 is provided with information and the like that can be used to play an online game.

  Steps 517 'to 522' are scenes in which an event occurs in which UE1 enters or leaves the CSG2 area position.

  In step 517 ', the occurrence of a CSG area location event is monitored by UE1, for example, UE1 has accessed HeNB2 connection or disconnected from HeNB2 or the HeNB2 identifier has been detected by UE1.

  In step 518 ', UE1 sends a location event report to the MME after establishing a connection with the circuit domain or group domain of the MME. According to the definition of the location event report, if it is a single location event report, after transmitting the report, UE1 finishes monitoring the occurrence of the location event, and if it is a plurality of location event reports, transmits the report. Later, UE1 continues to monitor the location event occurrence, but the time interval between the two reports does not exceed the minimum interval time.

  In step 519 ', the MME sends a user location report to instruct the GMLC to generate a CSG area location event.

  In step 520 ', the GMLC correctly receives the user location report and then returns a user location report confirmation to the MME, corresponding to step 519'. At this time, the MME can record the billing information.

  In step 521 ', the GMLC returns a location service response to the mobile service recommendation server, corresponding to step 502. At this time, the GMLC can record the billing information.

  In step 522 ′, the mobile service recommendation server initiates a mobile service push to UE2 based on information such as the service type definition requested by UE1 in step 501, mobile service recommendation definition, expiration date of request, etc. For example, presenting UE2 to share home network content with UE1.

  As shown in FIG. 6, in another embodiment of the present invention, the mobile service recommendation operation based on the detection of the CSG area location event includes the following steps.

  In step 601, a user registers a mobile service recommendation service based on sensing a CSG area location event, and logs in to a user portal provided by the operator via a UE or other communication method (eg, a network terminal). During the registration process, the user provides information such as one or more UE identifiers, CSG identifiers associated with each UE, service type definitions, mobile service recommendation definitions, and request expiration times. Specifically, this step corresponds to step 401 or step 501.

  In step 602, the network notifies the user via a short message, multimedia message, mail or other method whether the mobile service recommendation request has been successfully accepted. This step corresponds to step 413 or step 516.

  Specifically, the mobile service recommendation request can be sent to the user who sends the request and other users related to the user. In some cases, the portion for the user sending the request is accepted successfully, but the portion for other users associated with the user may be rejected. For example, when the UE2 does not send back the location event call confirmation in step 511, the mobile service recommendation confirmation returned from the network to the UE1 in step 516a notifies that the mobile service recommendation request for the UE2 has been rejected.

  In step 603, the UE reports a location event based on the CSG area. Specifically, after occurrence of a CSG area location event is monitored by the UE, a location event report is automatically transmitted from the UE to the network, and a presentation is transmitted to a user who uses the UE. This step corresponds to step 415, step 415 ', step 518 or step 518'.

  In step 604, the network pushes the mobile service to the UE via a short message, multimedia message, mail or other scheme, and in response, the UE receives the mobile service push. This step corresponds to step 419, step 419 ', step 522 or step 522'.

  As can be seen, in the flow according to an embodiment of the present invention, the mobile user customizes the mobile service recommendation service for one or more UEs (ie, registration process) to the mobile service recommendation server, and After a location event involving multiple CSG areas occurs, the UE senses the occurrence of the CSG area location event and automatically reports the location event report so that the mobile service recommendation server can respond to different location event types. Trigger to push the corresponding mobile service.

  In the system shown in FIG. 3, the CSG area location event management server generates a CSG area location event management target when a user registers a mobile service recommendation service. Specifically, FIG. 7 shows a configuration of a CSG area location event management target according to an embodiment of the present invention. As can be seen from FIG. 7, for the CSG area location event list corresponding to the UE identifier, each CSG identifier corresponds to one CSG area with each CSG area as an index, and each CSG area has one or more CSG areas. An area position event can be generated. In actual application, each CSG area location event may refer to a UE entering or leaving the CSG area.
