Description

Method and system for locking user position

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and a system for locking a user position.

Background

The Long Term Evolution (LTE) System is a Long Term Evolution of The Universal Mobile Telecommunications System (UMTS) technology standard established by The3rd generation Partnership Project (3 GPP) organization. Fig. 1 is a schematic diagram illustrating an LTE system architecture in the prior art, where the LTE system includes a Policy and Charging Enforcement Function (PCEF)/Packet Data Network Gateway (PGW), a Mobility Management Entity (MME), a Policy and Charging Rule Function (PCRF), a Home Subscriber Server (HSS), and other support nodes; wherein, PCEF/P-GW and PCRF all belong to the network element of the core network.

At present, with the development of broadband technology and the application of LTE technology, regional marketing is more and more common, how to acquire a User (UE) location and limit a specific preferential service to be used in a specific location becomes a problem of particular concern in the technical field of wireless communication. Currently, two schemes are mainly adopted for obtaining the location information of the UE: according to the first scheme, UE reports own initial position information when being activated, and a network side network element determines whether the UE is in an authorization range according to the initial position information of the UE; and secondly, the network side network element starts a real-time UE position reporting function, receives UE position information reported by the UE in real time, and determines whether the UE is in an authorized range according to the UE position information reported in real time.

In the process of implementing the present invention, the inventor finds that the existing scheme for acquiring the UE location information has at least the following defects:

in a first scheme, when a UE executes a service, a network element on a network side can determine a location of the UE only through initial location information of the UE reported when the UE is activated, so that when the UE moves, a Serving Gateway (SGW) change does not occur as long as the UE does not drop, and a PGW or a PCRF cannot perceive a location change of the UE, so that a corresponding service cannot be provided to the UE according to the location change of the UE.

In the second scheme, if the network element at the network side starts the real-time UE position reporting function, the network cannot bear the signaling load increased by geometric times, which seriously threatens the network security.

The following further describes embodiments of the present invention with reference to the drawings.

In a case where the PCRF compares the UE location, a request is sent to the PCRF by the PGW to trigger a qos parameter change procedure, an embodiment of the present invention provides a method for locking a user location, where as shown in fig. 2, the method includes:

step S200: the PCRF analyzes the received request sent by the PGW, and if the request carries the UE position information, the step S201 is switched to; if the request does not carry the UE position information, the step S202 is carried out;

here, the Request sent by the PGW is generally a Credit Control Request (CCR), where the CCR is configured to instruct the PCRF to allocate a service quality parameter, a time slice, and/or a traffic slice to the UE and return the service quality parameter, the time slice, and/or the traffic slice to the PGW, and generally, the PCRF carries the allocated service quality parameter, time slice, and/or traffic slice in a Credit Control response (CCA) and returns the CCA) to the PGW;

here, the PGW may send a request to the PCRF when it is determined that the UE is initially activated, and at this time, the PGW acquires UE initial location information and sends the request carrying the UE initial location information to the PCRF; or sending a request to the PCRF when it is determined that the UE has finished using the time slice or the traffic slice;

step S201: determining whether the UE is in an authorization range according to the UE position information, and distributing service quality parameters, time slices and/or flow slices to the UE and sending the service quality parameters, the time slices and/or the flow slices to the PGW when the UE is determined to be in the authorization range; when the UE is determined not to be in the authorized range, stopping providing service for the UE, and ending the process;

step S202: distributing service quality parameters, time slices and/or flow slices for the UE and sending the service quality parameters, the time slices and/or the flow slices to the PGW;

step S203: the PGW compares the received service quality parameter with the current service quality parameter of the UE, and if the service quality parameters are different, the step S204 is carried out; if the service quality parameters are determined to be the same, the step S205 is executed;

here, when receiving the initial service quality parameter, the PGW provides a service to the UE directly according to the initial service quality parameter, the time slice, and/or the traffic slice without performing comparison, and requests the service quality parameter, the time slice, and/or the traffic slice from the PCRF when the UE finishes using the time slice or the traffic slice;

here, when receiving the subsequent qos parameters, the PGW needs to compare the subsequent qos parameters with the qos parameters received last time, that is: comparing with the current service quality parameter of the UE;

step S204: acquiring new position information of UE (user equipment), providing service for the UE according to received service quality parameters, time slices and/or flow slices, and carrying the acquired new position information of the UE on the request to be sent to the PCRF when the UE finishes using the time slices or the flow slices, wherein the request is used for indicating the PCRF to determine whether the UE is in an authorization range according to the new position information of the UE;

step S205: and providing service for the UE according to the received service quality parameters, time slices and/or traffic slices, and requesting the service quality parameters, the time slices and/or the traffic slices from the PCRF when the UE finishes using the time slices or the traffic slices.

In a case that the PGW compares the UE location, the PGW sends a request to the PCRF or the PCRF actively pushes a quality of service parameter, a time slice, and/or a traffic slice to trigger a quality of service parameter change procedure, an embodiment of the present invention provides a method for locking a user location, where, as shown in fig. 3, the method includes:

step S301: PCRF distributes service quality parameters, time slices and/or traffic slices for user UE and sends the service quality parameters, time slices and/or traffic slices to PGW;

step S302: the PGW compares the received quality of service parameter with the current quality of service parameter of the UE, and if the quality of service parameters are different, the step S303 is performed; determining that the service quality parameters are the same, and turning to step S304;

step S303: acquiring new position information of UE, determining whether the UE is in an authorization range according to the new position information of the UE, and turning to step S304 when the UE is determined to be in the authorization range; when the UE is determined not to be in the authorized range, stopping providing service for the UE, and ending the processing flow;

step S304: and providing service for the UE according to the received service quality parameters, time slices and/or traffic slices, and requesting the service quality parameters, the time slices and/or the traffic slices from the PCRF when the UE finishes using the time slices or the traffic slices.

Here, the PCRF may actively allocate the quality of service parameter, the time slice, and/or the traffic slice to the UE according to a time interval manner, and send the allocated quality of service parameter, the time slice, and/or the traffic slice to the PGW, where the PCRF may send the Re-authorization Request (RAR) carried with the allocated quality of service parameter, time slice, and/or traffic slice to the PGW; or when receiving the request sent by the PGW, triggering the PCRF to allocate a quality of service parameter, a time slice, and/or a traffic slice to the UE and send the service quality parameter, the time slice, and/or the traffic slice to the PGW, where the request sent by the PGW may be a reputation control request; further, before step S301, the method further includes:

step S300: the PGW requests service quality parameters, time slices and/or traffic slices from the PCRF;

correspondingly, when the PCRF receives the request in step S301, the service quality parameter, the time slice, and/or the traffic slice are allocated for the UE and sent to the PGW.

Here, the PGW may obtain UE initial location information when determining that the UE is activated, determine whether the UE is within an authorization range according to the UE initial location information, and request the PCRF for a quality of service parameter, a time slice, and/or a traffic slice when determining whether the UE is within the authorization range; the PGW may also request the service quality parameters, time slicing, and/or traffic slicing from the PCRF when the UE has finished using the time slicing or the traffic slicing.

In the embodiment of the present invention, the PCRF needs to allocate the qos parameters to the UE according to the qos parameters normally subscribed by the UE, and the PCRF may allocate different qos parameters to the UE each time within the range of the qos parameters normally subscribed by the UE, for example, the qos parameters normally subscribed by the UE are 5, the qos parameters allocated to the UE for the first time are 5.001, the qos parameters allocated to the UE for the second time are 4.999, the qos parameters allocated to the UE for the third time are 5.002, …, and so on, so that the PCRF or the PGW can not only sense the location change of the UE and obtain the location information of the UE in the process of changing the qos parameters, determining whether the UE is in an authorized range according to the position information of the UE, thereby providing high-quality service for the UE in the authorized range and not influencing the use experience of a user; in addition, the time slice and the second time slice allocated by the PCRF for the UE at each time may be set according to actual needs of the user.
