Description

Service access control and neighbor cell query method, system, device and server

Technical Field

The present invention relates to the field of network communication technologies, and in particular, to a method, a system, an apparatus, and a server for service access control and neighbor cell query.

Background

In order to provide differentiated services for users, the 3GPP (3rd Generation Partnership Project) introduces a PCC (Policy Control and Charging) architecture in an EPS (Evolved Packet core System) network. The PCC architecture manages the bearer resources from end-to-end devices such as a terminal, a wireless network, a core network, and the like, can be associated with a charging policy, and realizes differentiation and refined management and control of data services by using policy control based on gating and Qos (Quality of Service) control and a flow-based charging control function, so that a perfect management and control means is provided for operators, and market marketing and operation policies are fully supported by network technologies.

Fig. 1 is a schematic diagram of a PCC architecture, which includes a UE (User Equipment), an eNodeB (base station), an MME (Mobility Management Entity), an saegw (system architecture evolution Gateway), generally, an SGW (Serving Gateway) and a PGW (Packet data Gateway) which are jointly configured and called SAE-GW, a PCEF (Policy and Charging enforcement Function) and a PCRF (Policy and Charging rules Function )/SPR (Subscription Profile Repository), and the SPR is generally deployed in a PCRF Function.

The PCRF and the PCEF are key network elements for implementing the PCC function. In practical application, the PCRF communicates with the service operation support system, includes a policy control decision and a function based on flow charging control, provides a network control function related to service data flow detection, gating, QoS-based and flow charging-based (except credit control) to the PCEF, and can generate a service control rule and issue the service control rule to the PCEF for execution by using multiple dimensions such as service, user, location, cumulative usage, access type, time, and the like as trigger conditions. The PCEF communicates with the service side, and includes functions such as detection of service data flow, policy enforcement, and flow-based charging, and the PCEF functional entity is generally deployed in a gateway device (e.g., an SGW, a PGW, etc.).

In a current LTE (Long Time Evolution) system, an event subscription capability of a PCRF is defined, and the PCRF may subscribe to a PGW for a series of events to monitor state change information of a user. For example, the PCRF may monitor change information of the TAI (Tracking Area Identity) where the UE is located by subscribing to the TAI _ CHANG event.

When the TAI of the UE CHANGEs, a TAU ((Tracking Area Update)/Handover) procedure is triggered, in which an eNB reports a current latest ULI (User location information) of the UE to an MME.

The PCRF can initiate a displacement CHANGE for the relevant USER moving across enbs by subscribing to the USER _ LOCATION _ CHANGE event. When the user has a mobility behavior across eNBs, the PCEF notifies the PCRF of the displacement condition of the user through a corresponding CCR message.

The PCRF can also obtain the real-time location CHANGE information OF the UE by subscribing to the CHANGE _ OF _ UE _ PRESENCE _ IN _ PRESENCE _ REPORTING _ AREA _ report event.

After subscribing to a CHANGE _ OF _ UE _ PRESENCE _ IN _ PRESENCE _ REPORTING _ AREA _ report event, when determining that a user enters or leaves a cell to be detected IN the subscription event, the PCEF transmits to the PCRF through a CCR message, so that the PCRF can obtain a behavior OF the UE entering or leaving a specific AREA.

In a service scenario where a CPE (Customer Premise Equipment) is locked, since the CPE is a wireless access device with relatively low traffic charges, the product is generally limited to be used by a party in a certain area, and when the CPE moves out of the limited area, the network access capability is limited or a preferential policy for canceling the traffic charges is applied; in addition, in a business scenario for a campus-like traffic offer package, a user may enjoy an offer of traffic tariffs on the campus to which the user is subscribed.

The services all present the characteristic that service charges or service experiences are closely related to the area where the user is located, so the network needs to be able to sense the location change of the user and correspondingly adjust the resource allocation policy and the charging policy of the user based on the current location of the user.

After introducing the PCC architecture, the LTE system may perform location-based policy control on the user, such as special preferential charging and modification of control policy on the user entering the defined area.

However, the above two existing schemes have their respective disadvantages for meeting the needs of the above two service scenarios. The TAI _ CHANG can be used to monitor the TAI level shift of the UE, but in the current network, one TAI usually includes tens or even hundreds of enbs, and the coverage area is relatively wide, so that the network sensing is relatively slow, and the user location cannot be accurately sensed.

And the CHANGE _ OF _ UE _ PRESENCE _ IN _ PRESENCE _ REPORTING _ AREA _ report event mainly monitors the user's actions IN and out OF a specific cell. However, currently, the area range to be monitored for the event needs to be manually pre-configured in the PCRF. In the two service scenarios, the control range for the user is usually about a range of more than ten cells, so when the event is used for control, the cost for manually maintaining the monitoring area is too high, and when the number of users becomes large, the manual maintenance mode is not feasible.

Detailed Description

In order to improve the accuracy of location-based service access control, embodiments of the present invention provide a method, a system, and a related device for service access control and neighbor query.

In a service scenario for performing service access control based on user location, an area for executing a specified service processing policy is usually a service access area formed by a plurality of neighboring base station cells, as shown in fig. 2, which is a schematic diagram of a neighboring area relationship. The area where the designated service processing policy is executed is a plurality of neighboring cells centered around the service anchor cell (cell 0), and all other cells in the area where the designated service processing policy is executed are cells neighboring the service anchor cell. The service anchor cell refers to a central cell that performs a specified service processing policy area (i.e., a service access area in the embodiment of the present invention). Based on this, the embodiment of the present invention provides a service access control method based on a neighboring cell relationship.

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.

As shown in fig. 3, an implementation flow diagram of the service access control method provided in the embodiment of the present invention may include the following steps:

s31, PCRF when detecting that the preset trigger event occurs, obtaining the first cell identification of the cell where the UE is currently located.

Preferably, in specific implementation, in order to perform service access control on the UE, the PCRF may periodically obtain a cell identifier of a cell in which the UE is currently located according to a preset period; or, the PCRF may monitor the displacement change condition of the UE in real time by subscribing to the location movement trigger event of the UE in advance. The LOCATION movement trigger event may be, but is not limited to, a TAI _ CHANGE event, a USER _ LOCATION _ CHANGE event, a CHANGE _ OF _ UE _ PRESENCE _ IN _ PRESENCE _ REPORTING _ AREA _ report event, and the like, and when the preset period reaches or detects the LOCATION movement trigger event OF the UE, the PCRF acquires the cell identifier OF the cell where the UE is currently located.

S32, PCRF according to the first cell ID judges whether the current cell of the UE is in any service access area included in the service access area list corresponding to the UE, if yes, step S33 is executed, if no, step S34 is executed.

The service access area is composed of a service anchoring cell and an adjacent cell thereof, wherein the service anchoring cell is bound by the UE in advance.

It should be noted that each UE may correspond to multiple service access areas, where the multiple service access areas form a service access area list corresponding to the UE, and when the UE is in a specific implementation, the UE may execute a corresponding service processing policy in any one of the service access areas.

And S33, processing the service requested by the UE according to the preset first service processing strategy, and ending the process.

S34, judging whether the number of the service access areas opened by the UE is equal to the number of the service anchor cells bound by the UE, if so, executing step S35, and if not, executing step S36.

And S35, processing the service requested by the UE according to a preset second service processing strategy, and ending the process.

And S36, triggering the process of binding the service anchoring cell.

In step S36, when determining that the number of cells activated by the UE is not equal to the number of service anchor cells currently bound by the UE, the PCRF triggers the short message gateway to send a notification message to the UE whether to bind the current cell as the service anchor cell, and if the short message gateway receives a confirmation message returned by the UE, the PCRF sends an anchor cell binding confirmation message to the BOSS, and the BOSS notifies the PCRF after receiving the anchor cell binding confirmation message, and the PCRF determines to bind the current cell as the service anchor cell.

In specific implementation, before the PCRF performs step S32, it may also query, according to the UE identity of the UE, whether the UE activates a location service for performing service access control based on the location; determining that the UE opens a service for performing service access control based on location (for convenience of description, in the embodiment of the present invention, a service for performing service access control based on location is referred to as a location service); and if the UE does not open the location service, directly processing the service requested by the UE according to a preset second service processing strategy.

Preferably, in the embodiment of the present invention, the service access area corresponding to the UE may be determined according to the following method:

step one, PCRF determines the adjacent cell of the service anchoring cell according to the second cell identification of the service anchoring cell bound by the UE.

And step two, the PCRF determines the service anchoring cell and the adjacent cell thereof as a service access area corresponding to the UE.

In specific implementation, after the PCRF determines the neighboring cell of each service anchor cell pre-bound by the UE, a region composed of the service anchor cell and the neighboring cell thereof is added to a service access region list as a service access region, which is a possible structure of the service access region list as shown in table 1:

TABLE 1

The service area access sequence number N in the service access area list is determined by the PCRF according to the determination sequence of the service access area in the service access area list, and N is a natural number greater than or equal to 1.

Specifically, the PCRF locally maintains a counter, the initial value of which is 0, each time the UE binds to a service anchoring cell, after receiving a service anchoring cell acknowledgement message sent by the BOSS, the PCRF adds 1 to the counter, determines, according to a cell identifier of the service anchoring cell currently bound by the UE, an adjacent cell identifier of the adjacent cell to add to a service area list, the service anchoring cell and the adjacent cell thereof constitute a service access area, and the PCRF uses the current value of the counter as a service access area sequence number of the service access area.

In specific implementation, due to the problems of wireless network optimization, network modification and the like, the adjacent cell of the service anchoring cell may have a change condition, and if the change condition of the adjacent cell information cannot be synchronized to the PCRF in real time, the PCRF may cause an error in the obtained adjacent cell information of the service anchoring cell, which leads to an error in a service access area determined based on the error, thereby reducing the accuracy of the service access control method based on the location.

In order to solve the problem, in the embodiment of the present invention, a cell list server may be used, where the cell list server is a centralized management unit that maintains cell information of a whole network, and maintains cell ID (identification) information, location information (which may be coordinates of a cell), neighboring cell information (which may include, but is not limited to, a neighboring cell identification), and the like of each cell of the whole network. In specific implementation, the cell list server may be independently configured or may be configured in an existing network device, which is not limited in the embodiment of the present invention. When cell information (such as a cell identifier and the like or neighbor cell information thereof) of a certain cell changes, the OMC notifies a cell list server of updating the stored cell information in real time, and the cell list server notifies the PCRF to update after updating the self-stored related information. The cell list server itself maintains a neighboring cell relation table for the PCRF to query, and maintains an access area relation table for storing a corresponding relation between the PCRF and the UE and its corresponding service access areas, which is described in detail below.

Based on the neighbor cell relation table stored by the cell list server, after determining the service anchoring cell bound by the UE according to the service anchoring cell binding acknowledgement message sent by the BOSS, the PCRF may determine the neighbor cell of the service anchoring cell bound by the UE according to the following steps:

step one, PCRF sends a neighbor relation query request to a cell list server.

And the neighbor cell relation query request sent by the PCRF carries the second cell identification of the service anchoring cell bound by the UE.

And step two, the PCRF receives the query result returned by the cell list server.

After receiving the neighbor relation query request sent by the UE, the cell list server searches the neighbor relation table stored therein according to the second cell identifier carried therein, where the cell identifier of the cell and the corresponding neighbor information thereof are stored in the neighbor relation table for each cell of the whole network, and the neighbor information may be a neighbor identifier, which is a possible structure of the neighbor relation table as shown in table 2:

TABLE 2

According to the stored neighbor cell relation table, after receiving the neighbor cell relation query request, the cell list server searches all the neighbor cell identifiers (i.e., the third cell identifier in the embodiment of the present invention) corresponding to the second cell identifier from the neighbor cell relation table, and carries the found neighbor cell identifiers in the query result returned to the PCRF.

It should be noted that, in the third cell identifiers returned by the cell list server, each third cell identifier corresponds to one cell, that is, there may be a plurality of neighboring cells of the service anchor cell that are bound in advance.

Preferably, in specific implementation, the neighboring cell relationship query request sent by the PCRF may further carry a UE identifier of the UE and a PCRF identifier of the PCRF, and after the cell list server finds a third cell identifier corresponding to the second cell identifier, the cell list server establishes a corresponding relationship between the UE identifier and the second cell identifier (i.e., a cell identifier of a service anchoring cell bound by the UE) and the third cell identifier (i.e., a neighboring cell identifier of a service anchoring cell bound by the UE) and the PCRF identifier, and stores the corresponding relationship in the service access area relationship table, as shown in table 3, a possible table structure for the service access area relationship table is as follows:

TABLE 3

UE identity

Service anchoring cell identification

Service anchoring cell adjacent cell identification

PCRF identification

Step three, the PCRF determines that the cell corresponding to each third cell identifier is the neighbor cell of the service anchoring cell pre-bound by the UE.

Specifically, after receiving the query result returned by the cell list server, the PCRF determines, according to the third cell identifier carried in the query result, that the service access area corresponding to the UE is a cell corresponding to each of the second cell identifier and the third cell identifier, and stores the cell into the local service access area list, and then the PCRF may execute a corresponding service processing policy on the UE according to whether the UE is located in any service access area included in the service access area list.

In the wireless network optimization process, base stations may be newly added or deployed base stations may be closed in a certain area according to the actual number of users in the area, so that the neighbor cell information of each cell may change, and in order to ensure the timeliness of the neighbor cell relation table stored in the cell list server, in the embodiment of the present invention, the neighbor cell relation table stored in the cell list server may be updated according to the following method: a cell list server receives a cell information update message reported by an Operation and Maintenance Center (OMC), wherein the cell information update message carries a cell identifier of a cell to be updated and cell information after updating, and the cell information may include a cell identifier and cell neighbor information (which may be a neighbor identifier); and the cell list server updates the cell information of the cell corresponding to the cell identifier carried in the cell information updating message in the neighbor cell relation table according to the received cell information updating message.

It should be noted that, after updating the neighbor relation table, the cell list server also needs to update the service access area relation table (i.e. table 3) synchronously, and in addition, the cell list server also needs to notify the corresponding PCRF to update the service access area table (i.e. table 1) stored therein. After updating the neighbor relation table, the cell list server may further determine whether the cell identifier carried in the cell information update message exists in the service access area relation table, and if so, update the service access area relation table according to the updated cell information corresponding to the cell identifier; and sending a cell information updating notification message to the corresponding PCRF according to the PCRF identifier corresponding to the cell identifier in the service access area relation table, wherein the cell identifier of the cell to be updated and the cell identifier obtained after updating and/or all the adjacent cell identifiers corresponding to the cell identifier are carried, and the PCRF updates a service access area list stored by the PCRF after receiving the cell information updating notification message. Specifically, the PCRF updates the cell identifier corresponding to the service access area list stored in the PCRF according to the cell identifier carried in the cell message update notification message and the updated cell information thereof, to be the updated cell identifier and/or the updated neighbor cell identifier.

Taking table 2 as an example, in the process of optimizing the wireless network, the information that may change includes: firstly, the cell identification changes; secondly, the adjacent cells of the cell are changed due to the increase or the close of the base station, and both the adjacent cells are possibly changed.

First, assume that only the cell identity changes

This situation is relatively simple, and only the CELL identifier of the corresponding CELL in the neighboring CELL relationship table needs to be updated, and the corresponding CELL identifier in the service access area relationship table needs to be updated synchronously, assuming that CELL ID1 in table 2 is updated to CELL ID11, then CELL information update message sent by the OMC to the CELL list server carries CELL ID1 and its updated CELL identifier CELL ID11, accordingly, the CELL list server updates CELL ID1 in table 2 to CELL ID11, and synchronously updates CELL ID1 in table 3 to CELL ID11, in addition, the CELL list server also needs to determine and search PCRF identifier corresponding to CELL ID1 according to table 3 before updating table 3, so as to notify the corresponding PCRF, and update CELL ID1 in the service access area list stored therein to CELL ID 11.

Second, the adjacent area changes

It should be noted that, in the embodiment of the present invention, only when a certain cell is a service anchor cell bound to the UE, a change in an adjacent cell thereof will affect the accuracy of service access control. Therefore, the embodiment of the present invention also relates to a processing flow only when the neighboring cell of the service anchor cell changes.

Still taking table 2 as an example, assuming that the neighbor CELL identifier corresponding to CELL ID1 changes to CELL ID2, CELLID4 and CELLID11, after the CELL list server receives the CELL information update message, according to the carried CELL identification CELLID1, the CELL identifications corresponding to the CELL ID1 in the CELL relation table are modified to be CELL ID2, CELLID4 and CELL ID11, and modifies the access relation table of the service area, the service anchoring CELL ID is CELL ID1 corresponding to the adjacent CELL ID2, CELLID4 and CELL ID11, in addition, the cell list server informs PCRF to modify the service access area list stored in the PCRF, and the service anchoring CELL identifier is CELL ID2, CELLID4 and CELL ID11 corresponding to the CELL ID1, and the PCRF updates the neighbor CELL identifier corresponding to the CELL ID1 in the service access list stored by the PCRF to CELL ID2, CELLID4 and CELL ID11 according to the notification message of the CELL list server, so that the synchronous updating of the service access area list stored in the PCRF is completed. Therefore, timeliness of the service access area list stored in the PCRF can be guaranteed, and accuracy of service access control based on the position is improved.

In specific implementation, if the cell identifier and the neighbor cell identifier both change, the update procedure may refer to the update procedure when only the cell identifier or only the neighbor cell identifier changes, which is not described herein again.

In specific implementation, the OMCs may perform distributed setting according to different areas, each OMC is responsible for maintaining a cell identifier of a cell in a designated area, and reports the cell identifier of the cell in the designated area or corresponding neighbor information to a cell list server in real time after updating. If the cell identifier of the cell to be updated carried in the cell information updating message received by the cell list server does not exist in the pre-stored neighbor cell relation table, the cell list server can newly add the corresponding relation between the cell identifier and the neighbor cell information in the neighbor cell relation table. If the deployed base station is closed, the OMC reports the cell identifier of the cell covered by the closed base station to a cell list server, and the cell list server deletes the cell identifier of the corresponding cell in a neighbor cell relation table and the corresponding relation between the neighbor cell information of the cell identifier. And correspondingly modifying the service access area relation table, and informing the PCRF to modify the stored service access area list.

It should be noted that, in order to distinguish a CELL identifier of a CELL in which the UE is currently located from a CELL identifier of a service anchor CELL that is pre-bound by the UE in the embodiment of the present invention, a CELL identifier of a CELL in which the UE is currently located is referred to as a first CELL identifier, a CELL identifier of a service anchor CELL is referred to as a second CELL identifier, and both the first CELL identifier and the second CELL identifier are CELL identifiers that are commonly referred to, for example, the first CELL identifier may be a CELL ID of a CELL in which the UE is currently located, and the second CELL identifier may be a CELL ID of the service anchor CELL. Similarly, the third/fourth/fifth/sixth cell identifiers involved in the embodiment of the present invention are also only used for partitioning different cell identifiers.

In specific implementation, the PCRF may execute different service processing policies for the UE according to the actual location of the UE after the UE opens the location service. Initially, when a UE opens a service for performing service access control based on a location, a BOSS (Business & Operation Support System) synchronizes service state information of a user to a PCRF through a related interface, where the service state information mainly includes the following four types of information:

the location policy user identifier is used for indicating whether the UE subscribes a service for performing service access control based on location, and in specific implementation, the "1" may be used to mark that the UE subscribes a service for performing service access control based on location, and the "0" may be used to mark that the UE does not subscribe a service for performing service access control based on location.

And a service state binding identifier, configured to instruct the PCRF to bind the current cell as a service anchor cell, specifically, a "0" may be used to indicate no binding, and a "2" may be used to indicate binding.

And the service initial state identifier is used for identifying the number of the service access areas opened by the UE.

And the service state refreshing identifier is used for indicating the PCRF to refresh the binding relationship of the service access area of the user, wherein '0' is used for indicating all refreshing, and 1/2/3 … …/m indicates the binding relationship of the mth service access area corresponding to the designated refreshing.

And the PCRF performs operations such as binding, refreshing or deleting the service access area according to the message sent by the BOSS.

In the embodiment of the present invention, the following two implementation manners for determining a service anchor cell are provided:

the first embodiment,

As shown in fig. 4a, an implementation flow diagram for determining a service anchor cell after a UE opens a service for performing service access control based on a location in the embodiment of the present invention may include the following steps:

s411, the user sends an attach request to the PCRF through the UE at the location desired to be set as the service anchor cell.

The attach request carries the UE identity of the UE.

S412, PCRF inquires whether the UE opens the location service for service access control based on location.

During specific implementation, the PCRF may search, according to the UE identifier carried in the attach request, a location policy user identifier corresponding to the UE identifier, determine that the UE has opened a location service for performing service access control based on the location if the UE identifier is "1", and determine that the UE has not opened a location service for performing service access control based on the location if the UE identifier is "0".

In specific implementation, if the location service for performing service access control based on the location is not opened to the UE, service access control may be performed on the UE according to a preset second service processing policy.

S413, the PCRF triggers the short message gateway to send a service anchoring cell binding request to the UE.

S414, the short message gateway sends a service anchoring cell binding request to the UE.

S415, the UE sends a service anchor cell binding request acknowledgement message to the short message gateway.

S416, the short message gateway sends a service anchoring cell binding confirmation message to the BOSS.

S417, the BOSS sends a service anchor cell binding acknowledgement message to the PCRF.

In specific implementation, after receiving a service anchoring cell binding request confirmation message sent by the short message gateway, the BOSS updates the service state binding identifier of the user to a binding state, that is, modifies the service state binding identifier to "2", and notifies the PCRF.

S418, PCRF determines that the current attached cell of UE is the service anchoring cell bound by UE.

In specific implementation, after determining the service anchoring cell bound by the UE, the PCRF needs to further determine a service access area corresponding to the UE according to the service anchoring cell.

S419, PCRF inquires the neighbor cell of the currently bound service anchoring cell from the cell list server.

Specifically, the PCRF sends a neighboring cell relation query request to the cell list server, where the neighboring cell relation query request carries a cell identifier of a service anchor cell currently bound by the UE.

S4110, the cell list server returns the query result to the PCRF.

And the cell list server searches the corresponding neighbor cell identification according to the cell identification carried in the received neighbor cell relation query request, and returns the searched neighbor cell identification to the PCRF.

S4111, the PCRF determines the service access area bound by the UE according to the query result.

Specifically, the PCRF determines a service anchor cell currently bound by the UE and a neighboring cell of the service anchor cell that is queried as a service access area bound by the UE.

After determining the service access area bound by the UE, the PCRF may execute different service processing policies for the UE according to the location information of the UE.

In specific implementation, if a user opens a service for performing service access based on a location in multiple areas, the PCRF determines, after the user opens the service for performing service access based on the location, whether the number of service access areas that the UE has opened is equal to the number of service anchoring cells that the UE has bound to according to the service initial state identifier, and if not, searches whether a cell to which the UE is currently attached exists in service access areas included in a service access area list corresponding to the UE; if not, triggering the short message gateway to send a service anchoring cell binding request to the UE; after receiving a service anchoring cell binding request confirmation message sent by the UE, the short message gateway sends the service anchoring cell binding confirmation message to the BOSS; the BOSS informs the PCRF after receiving a service anchoring cell binding confirmation message; and the PCRF determines that the current attached cell of the UE is the service anchoring cell bound by the UE.

The second embodiment,

A user sends a service anchor cell binding request to a short message gateway through a UE at a location where the user desires to bind as a service anchor cell, and the short message gateway triggers to execute step S416 in fig. 4 after receiving the service anchor cell binding request, specifically, as shown in fig. 4b, the method may include the following steps:

s421, UE sends service anchoring cell binding request to short message gateway.

Specifically, the UE carries the UE identity of the UE in the service anchor cell binding request sent to the short message gateway.

S422, the short message gateway sends a service anchoring cell binding confirmation message to the BOSS.

Specifically, the short message gateway carries the UE identity of the UE in the service anchor cell binding acknowledgement message sent to the BOSS.

And S423, the BOSS sends a service anchoring cell binding confirmation message to the PCRF.

In specific implementation, after receiving a service anchoring cell binding confirmation message sent by the short message gateway, the BOSS updates the service state binding identifier of the user to a binding state, that is, modifies the service state binding identifier to "2", notifies the PCRF, and carries the UE identifier of the UE in the sent service anchoring cell binding confirmation message.

S424, PCRF confirms that the cell where UE is currently located is the service anchoring cell bound by UE.

Specifically, the PCRF obtains a cell identifier of a cell where the corresponding UE is currently located according to the UE identifier carried in the service anchoring cell binding acknowledgement message, and determines the corresponding cell as the service anchoring cell to which the UE is bound.

S425, the PCRF inquires the neighbor cell of the currently bound service anchoring cell from the cell list server.

S426, the cell list server returns the query result to the PCRF.

And S427, the PCRF determines the service access area bound by the UE according to the query result.

In specific implementation, a user can perform operations such as refreshing and deleting a service access area through the UE according to actual needs, and preferably, the user can send a data short message to the short message gateway through the UE to perform operations such as refreshing and deleting the service access area.

As shown in fig. 5, which is a schematic diagram of an implementation flow for performing service access area refresh in the embodiment of the present invention, the implementation flow may include the following steps:

s51, the UE sends a service access area refreshing request to the short message gateway.

The service access area refreshing request carries a service state refreshing identifier and a UE identifier of the UE.

And S52, the short message gateway forwards the received service access area refreshing request to the BOSS.

And S53, the BOSS forwards the received service access area refreshing request to the PCRF.

S54, PCRF determines the service access area sequence number corresponding to the service access area requested to be refreshed by UE.

Specifically, the PCRF determines the service access area sequence number corresponding to the service state refresh identifier carried in the service access area refresh request according to the correspondence between the preset service state refresh identifier and the service access area sequence number.

Specifically, if the service state refresh flag is "0", it indicates full refresh, in this case, the PCRF determines that the service access area sequence numbers corresponding to the service state refresh flag are all service access area sequence numbers included in the service access area list corresponding to the current UE, if the service state refresh flag is "1/2/3 … …/m", it indicates that the PCRF refreshes the designated service access area, and the PCRF determines that the service access area sequence number is m (m is not greater than N) according to the service state refresh flag.

S55, PCRF cancels the corresponding relation between the UE corresponding to the UE identification and the service access area corresponding to the determined service access area sequence number.

Specifically, the PCRF releases the binding relationship between the UE and the service access area corresponding to the determined service access area serial number, and notifies the cell list server to delete the stored correspondence between the UE and each cell identifier included in the service access area.

In specific implementation, if the UE cancels the service for controlling the service access based on the location, the PCRF needs to delete the service access area list corresponding to the UE, as shown in fig. 6a, which is an implementation flow diagram for deleting the service access area list corresponding to the UE, the implementation flow may include the following steps:

s61, the UE sends the message for canceling the service access control service based on the position to the short message gateway.

S62, the short message gateway transmits the received message for canceling the service access control service based on the position to the BOSS.

The UE identifier carries the UE identifier of the UE.

And S63, the BOSS sends an indication message for deleting the service access area list corresponding to the UE to the PCRF.

The BOSS carries the UE identity of the UE in the sent indication message, and marks the location policy user identity as '0'.

S64, PCRF deletes the service access area list corresponding to the UE identification.

And after deleting the service access area list corresponding to the UE identifier, the PCRF informs the cell list server to delete the corresponding relation between all cell identifiers contained in all service access areas corresponding to the UE and stored by the cell list server.

In order to better understand the embodiment of the present invention, the service access control method provided in the embodiment of the present invention is described below with reference to a specific implementation process of the embodiment of the present invention.

Initially, a user may use his own UE to open a location service to a communications operator in a business hall, and determine the number of service access areas to be opened, and subsequently, the communications operator may provide location-based service access control for the user through a deployed PCRF according to the UE identity of the UE when the user opens the location service. In specific implementation, the user may also open the location service through a website or client software. In specific implementation, a communication operator needs to determine a service access area corresponding to the user in combination with the service anchor cell bound by the user.

After the user opens the location service, the service anchoring cell can be bound in an active mode or a passive mode. Wherein:

the active binding mode is that a user actively sends a service anchoring cell binding message to a short message gateway through UE, wherein the service anchoring cell binding message carries a UE identification, the short message gateway forwards the received service anchoring cell binding message to a BOSS, the BOSS receives the message and then informs a PCRF, the PCRF acquires a cell where the UE is currently located according to the UE identification, and determines the cell where the UE is currently located as one of service anchoring cells bound by the UE, and in specific implementation, the PCRF only needs to control the number of the service anchoring cells bound by the user not to exceed the number of the service access areas opened by the PCRF.

The user binds the service anchoring cell in a passive binding mode, namely, when the UE initiates an attachment request to the PCRF, the PCRF judges whether the UE opens a position service, if the position service is opened, the UE is further judged whether to bind at least one service anchoring cell, if the UE is not bound with any service anchoring cell, the PCRF triggers a short message gateway to send a service anchoring cell binding request to the user, inquires whether the user binds the current cell as the service anchoring cell, if the user wants to bind the current cell as the service anchoring cell, a confirmation message is sent to the short message gateway, and if the user does not want to bind the current cell as the service anchoring cell, no reply is needed or an indication message for not binding the current cell as the service anchoring cell is sent to the short message gateway. After receiving a confirmation message for binding the current cell to be the service anchoring cell, the short message gateway sends a service anchoring cell binding confirmation message to the BOSS, wherein the service anchoring cell binding confirmation message carries the UE identification of the UE, the BOSS sends the service anchoring cell binding confirmation message to the PCRF, wherein the service anchoring cell binding confirmation message carries the UE identification of the UE, and the PCRF determines to bind the corresponding UE current attachment cell to be the service anchoring cell according to the UE identification. If the PCRF judges that the UE is bound with at least one service anchoring cell, the PCRF can continuously judge whether the cell where the UE is currently located is in a service access list corresponding to the UE, if not, a service anchoring cell binding process is triggered, namely, a short message gateway sends a service anchoring cell binding request to a user, inquires whether the user binds the cell where the UE is currently located as the service anchoring cell, if the user wants to bind the cell where the UE is currently located as the service anchoring cell, a confirmation message is sent to the short message gateway, and if the user does not want to bind the cell where the UE is currently located as the service anchoring cell, an indication message for not binding the cell where the UE is currently located as the service anchoring cell is not required to be replied or sent to the short message gateway. After receiving a confirmation message for binding the current cell to be the service anchoring cell, the short message gateway sends a service anchoring cell binding confirmation message to the BOSS, wherein the service anchoring cell binding confirmation message carries the UE identification of the UE, the BOSS sends the service anchoring cell binding confirmation message to the PCRF, wherein the service anchoring cell binding confirmation message carries the UE identification of the UE, and the PCRF determines to bind the corresponding UE current attachment cell to be the service anchoring cell according to the UE identification.

After each UE binds to a service anchor cell, the PCRF may send a neighbor cell relation query request to the cell list server to request for querying a neighbor cell of the service anchor cell, where the neighbor cell carries a cell identifier of the service anchor cell bound by the UE, and after receiving the neighbor cell relation query request, the cell list server queries, according to the cell identifier carried in the neighbor cell relation query request, all neighbor cell identifiers corresponding to the cell identifier in a neighbor cell relation table stored in the PCRF, and returns a query result to the PCRF, where the neighbor cell identifiers carry all neighbor cell identifiers corresponding to the cell identifier found by the PCRF in the neighbor cell relation query request. In addition, the cell list server also needs to establish a corresponding relationship between the UE identity, the PCRF identity, the cell identity of the service anchoring cell currently bound by the UE, and the neighbor identity of the service anchoring cell according to the found neighbor identity, and store the corresponding relationship in the service access area relationship table. And the PCRF determines a service access area determined according to the service anchoring cell currently bound by the UE according to the query result, wherein the service access area consists of the service anchoring cell currently bound by the UE and an adjacent cell thereof. And the PCRF adds the cell identifier of the service anchoring cell bound by the UE and the neighbor cell identifier of the neighbor cell thereof to a service access area list stored by the PCRF.

If in the wireless network optimization process, when the cell list server receives a cell information update request reported by the OMC, the cell list server updates the cell information corresponding to the cell identifier according to the cell identifier carried in the cell information, and the cell information may include the cell identifier after updating the cell identifier and the adjacent cell identifier after updating the cell identifier. The cell list server updates the cell information of the corresponding cell identification according to the received cell information updating request, further judges whether the cell identification exists in the service access area relation table, and if the cell identification exists in the service access area relation table, the cell list server updates the cell information of the corresponding cell identification in the service access area relation table. And informing the PCRF to update the cell information of the corresponding cell identifier in the service access area list stored by the PCRF.

After the user opens the location service, the PCRF may implement the following steps according to fig. 6 b:

s601, PCRF judges whether a preset trigger event is detected, if yes, the process is ended, otherwise, step S602 is executed.

The preset trigger event may be a preset period, or a location movement trigger event of the UE is detected.

S602, the PCRF determines whether the UE opens the location service, if so, then step S603 is performed, otherwise, step S608 is performed.

Specifically, the PCRF may determine whether the UE activates the location service according to the location policy subscriber identity synchronized by the BOSS, where if the location policy subscriber identity is 1, it indicates that the UE activates the location service, and if the location policy subscriber identity is 0, it indicates that the UE does not activate the location service.

S603, the PCRF determines whether the UE is currently bound with at least one service anchor cell, if so, performs step S604, otherwise, performs step S607.

Specifically, the PCRF may determine whether the service access area list corresponding to the UE is stored in the PCRF, and if so, indicate that the UE is bound to at least one service anchor cell, otherwise, indicate that the UE is not bound to any service anchor cell.

S604, the PCRF judges whether the cell identification is in a service access list corresponding to the UE according to the acquired cell identification of the cell in which the UE is currently located, if so, the step S605 is executed, otherwise, the step S606 is executed.

S605, the PCRF determines to process the service requested by the UE according to a preset first service processing strategy, and the process is finished.

S606, the PCRF determines whether the number of the service anchor cell bound by the UE is the same as the number of the service access area opened by the UE, if so, performs step S608, otherwise, performs step S607.

Specifically, the PCRF determines the number of service anchor cells currently bound by the UE according to the maximum sequence number of the service access area in the service access list corresponding to the UE stored in the PCRF, compares the number of the service anchor cells currently bound by the UE with the number of the service access area activated by the UE indicated in the service initial state identifier synchronized with the BOSS, and determines whether the number of the service anchor cells is equal to the number of the service access area activated by the UE.

S607, PCRF triggers the short message gateway to execute the binding process of the service anchoring cell.

Specifically, the PCRF triggers the short message gateway to send a service anchor cell binding request to the UE, and after determining that the UE returns a service anchor cell binding request confirmation message, the short message gateway sends a service anchor cell binding request confirmation message to the BOSS, where the service anchor cell binding request confirmation message carries the UE identifier of the UE. And after receiving the service anchoring cell binding request confirmation message, the BOSS sends the service anchoring cell binding request confirmation message to the PCRF, and the PCRF determines the cell in which the UE is currently located as the service anchoring cell bound by the UE. And inquiring the neighbor cell of the cell from the cell list server, and determining the service access area corresponding to the UE. Subsequently, when the PCRF determines that the UE is located in any service access area included in the corresponding service access area list, the service requested by the UE is processed according to a preset first service processing policy.

S608, the PCRF determines to process the service requested by the UE according to a preset second service policy.

The service access control method provided by the embodiment of the invention determines and executes the service processing strategy corresponding to the UE according to whether the UE is located in the service access area which is bound in advance, wherein the service access area which is bound in advance is determined according to the service anchoring cell which is bound in advance by the UE and the adjacent cell thereof, so that the service access control based on the user position is more accurate. Meanwhile, the neighbor cell relation of the service anchoring cell is ensured by synchronizing the neighbor cells of the service anchoring cell bound by the UE in real time when the neighbor cells of the service anchoring cell bound by the UE are changed by means of the cell list server, and the accuracy of service access control is further improved.
