Taking the UMTS network as an example, the AP can be used as a home or enterprise device to limit access to the UE by setting a user admission list. Different user admission levels can also be set to distinguish the priority of the same AP. However, in the current charging scheme, differentiated charging between different types of users cannot be implemented. In addition, it can be understood that the above different types are used. Users may belong to different types of users under the same AP, or may belong to different types of users under different APs.

In the embodiment of the present invention, a method for implementing differentiated charging is provided. As shown in FIG. 1, the method includes the following steps:

Step sl01: Select, according to the access identity of the user equipment accessing the access point AP, the user equipment identity corresponding to the admitted identity for the user equipment.

Specifically, the AP on the network side stores a preset admission list, where the admission list includes different identifiers of the user equipments and their corresponding access identities. When receiving the access request from the user equipment, the AP on the network side can obtain the identity of the user equipment itself, such as the mobile phone number of the user equipment, IMSI (International Mobile Subscriber Identity), etc., and the AP can be locally A pre-set access list is obtained to obtain the access identity of the user equipment.

The AP can obtain the identity identifier corresponding to the user equipment access identity according to the access identity of the user equipment and the correspondence between the pre-set admission identity and the identity identifier.

Step s 102: Generate a message carrying the identity identifier of the user equipment.

Step sl03: Send a message carrying the identity of the user equipment to the network side, and use the network side to charge the user equipment.

Specifically, the AP may send the foregoing message carrying the identity of the user equipment to the network side, and the charging system on the network side according to the pre-configured different charging policies for different user equipment identity identifiers, according to the specific charging policy of the user equipment. Billing is performed, thereby achieving differentiated charging for different user equipments. The implementation method of differentiated charging in the embodiment of the present invention is further described in the following with reference to a specific application scenario.

First, describe the possible access status of the UE (User Equipment) in the network. Taking the networking diagram shown in Figure 2 as an example, an AP network (LAC10) is deployed in the macro network (LAC1), including AP3 in Open access mode, AP4 in Close access mode, and Group admission mode. API and AP2; You can assign a different SAC (Service Area Code) to each AP deployment area or each AP. The following describes different modes:

(1) In Open Admission mode, all UEs access the AP3 as ordinary Everyman.

(2) In the 1 (^ admission mode, in addition to the UE as a member of the family accessing the AP4 as a member member, the UE as a relative friend can also be configured to access the AP4 as a friend Friend. In addition, for the operator's needs It is also possible to reserve an admission for other UEs, for example, to access the AP4 as a temporary guest guest. The Close mode includes only the local admission mode, that is, for the AP4 that does not participate in the group admission, only in the local admission list. The UE can access it.

(3) In the Group admission mode, two application scenarios can be considered:

A. The community enterprise scenario, that is, multiple APs used by multiple households form a group. In this group, there may be two members and members in one UE. That is, the UE can be connected to the member in the home. Into the AP, you can also access the APs in other households in the group as a member of the Associator. At this time, the AP's admission mode is the Group admission mode, and also includes the local admission mode.

B. The corporate community scenario, that is, multiple APs in the office form a group. In this group, the UEs may all be the same staff Staffer identity, and may also allow other UEs to be identified. For example, some APs may also allow Guest users to connect. In.

For each of the different identities that the UE has, each identity has a corresponding priority. That is, in a certain admission mode, when the access resource is limited, according to the admission priority corresponding to the user-specific identity, which user is preferentially admitted and which user is allowed to enter. The basic principles are as follows: 1) For local admission, the member member is the first. 2) If the UE has the local access identity of an AP in a certain group and the group access identity of the group, the UE accesses the AP preferentially in the local access mode; if the UE does not have the local access identity in an AP, select Group access identity access. In addition, since the member Associator identity and the staff Staffer identity have the same admission level in the Group admission mode, they belong to the group members in the Group access list, so the priorities are the same. 3) For Open mode, there is no user access priority, but if there is Half-open (in addition to local admission, UEs other than local admission are allowed to enter with the lowest priority Everyman) Or Group-open access mode (refers to both local admission or group admission, and allows UEs other than local admission or group admission as the lowest priority Everyman admission), then the common identity Everyman has the lowest priority.

Based on the above situation, the mapping between the identity and the priority of the UE in different AP admission modes can be as shown in Table 1. The smaller the priority number, the higher the priority.

Table 1: Correspondence between the UE identity, the AP's admission mode, and the priority

For different UE identities in the above-mentioned one AP or a group of APs, when different identities of different UEs need to be differentiated, the different identities of the UEs may be differently identified on the AP. For the UMTS network, the CDR and SAC parameters are generated in the CDR CDRs generated by the CN. Therefore, you can consider using the LAC and SAC parameters as the UE identity to implement differentiated accounting. Specifically, in the charging system, different LACs/SACs correspond to different charging rates. For different UEs, the AP distinguishes the UEs through the LAC/SAC and uplinks the core network, and the core network notifies the charging system. The charging system can implement differentiated charging according to different rates configured by different LAC/SACs.

Take the identifier as the SAC as an example: Configure different SACs for different UE identities, implement different user identity identities, and differentiated accounting. As shown in Table 2, multiple SACs (SAC-Member, SAC-Friend, SAC-Guest, etc.) can be configured on the AP according to the needs of differentiated charging. Different UE identities correspond to different SACs. Table 2: UE identity, priority, and SAC correspondence

When the description is required, the Associator identity and the staff Staffer identity of the member are the same in the group admission mode, and the priority is the same, but the differentiated charging may be required. Therefore, the enterprise enterprise scenario and the community community scenario use SAC-GroupE respectively. It is distinguished from the SAC-GroupC. When configuring parameters for an AP, you can choose one according to the application scenario. Of course, if the actual network operation process does not require differential accounting for the Associator identity and the staff Staffer identity, then the SAC-Group can be used without distinction.

After obtaining the identity of the user equipment, the AP generates a message carrying the identity of the user equipment according to the identity of the user equipment, and sends the message to the network side. On the network side, a charging policy with different identity identifiers (such as LAC or SAC) is configured. The network-side charging system uses this policy to use different charging rates for different user equipment identifiers (such as LAC or SAC). To enable differentiated charging based on different user device identities such as LAC or SAC.

The following takes the user equipment identity as the SAC as an example. In this case, there is no impact on the use of the LAC identifier in the prior art. For example, different LACs can be used to distinguish between macro coverage and AP coverage, and interaction between the user equipment, the AP, and the network side. Whether the LAC identifier is carried in the message is not affected by the SAC identifier in the technical solution of this embodiment. Specifically, the SAC configuration policy in the network can include the following two types:

Configuration strategy 1: The service-based layer is divided into two types of SACs, which are used for positioning. The SAC (hereinafter referred to as "positioning SAC") and the special SAC for billing (hereinafter referred to as "billing SAC").

Each AP can be configured with multiple SACs, including for accounting for SAC, and for locating SAC. The charging SAC may be further extended based on the UE identity division, so that the message sent by the AP selects a corresponding charging SAC for different UE identity. For emergency calls, LCS (Location Service), and Relocation related messages, the SAC is selected for all UEs.

The accounting SAC for differentiated charging is unique within the AP network. The positioning SAC can be the same as the SAC of the macro network (that is, the positioning accuracy is the same as that of the macro network). You can also assign different SACs to each AP deployment area in a LAC range, or assign different SACs to each AP. A possible division of accounting SAC and positioning SAC is shown in Table 3.

Table 3. Accounting SAC and positioning How to divide SAC

Configuration Strategy 2: Divide two or more SACs based on the UE identity level.

Specifically, each SAC corresponds to a UE identity, and all services corresponding to the identity of the UE use the SAC, including uplink direct messaging, LCS, emergency call, and Relocation. Wait. Moreover, these SACs are all planned by the network plan (not a special SAC), and have practical positional significance, except that multiple SACs configured on the same AP are physically the same area.

A specific implementation manner of the configuration strategy 2 is as shown in FIG. 3, and each AP in the Close admission mode in the area 1 (assumed to be a residential area) is configured with three SACs, respectively, SAC11 (SAC) for the member status. -Member ) , SAC 12 ( SAC-Friend ) for Friend identity and SAC13 ( SAC-Guest ) for Guest identity. When the UE accesses the area 1, the AP selects the corresponding SAC according to the access identity of the UE. There are three SACs in area 1. If the MSC needs to configure the corresponding SAC for emergency calls, then all three SACs need to be configured and represent the same location area, that is, the same emergency center. If there are more identity levels to be differentiated, the AP needs to configure more SACs, such as the Group mode community scenario. The AP also needs to configure SAC14 for membership.

Similarly, each AP in Zone 2 (assumed to be an enterprise) is configured with two SACs, SAC21 (SAC-GroupE) for the Staffer identity, SAC22 (SAC-open) for the Everyman identity, and only the Staffer identity. , you only need to configure one SAC21 ( SAC-GroupE ).

In the LAC range of another AP, in addition to the above-mentioned SAC allocation in an AP deployment area (such as the above area 1 and area 2), it is also possible to assign different addresses to another AP (such as the area 1 and area 2 above). SAC. When configuring different APs one by one, the required SAC configuration is larger. After obtaining the identity of the user equipment, the AP needs to send the identity of the user equipment to the core network. For example, the user equipment identity is the SAC, and the AP can carry the SAC of the user equipment in the direct transmission message of the RANAP (Radio Access Network Application Part), where the INITIAL UE MESSAGE (uplink direct message) The SAI (Service Area Identity) is mandatory, and the SAI in the DIRECT TRANSFER is optional. These SAIs are all from the AP. The AP can directly change the SAC in the SAI to the corresponding special SAC (SAC-Member, SAC-Friend, SAC-Guest, SAC-Group, etc.) according to different user access identities. For the configuration of the above two types of SACs, the identity of the user equipment can be differentiated by the SAC identifier. The SAC identifier can be sent to the core network and the charging system. Differentiated billing for user equipment. The following describes the implementation of the present invention in combination with two specific application scenarios. The SAC configuration policy used in the two application scenarios may be any one of the foregoing two SAC configuration policies.

In the first application scenario, an AP supporting the Close admission mode is taken as an example. If the UE on the AP can be accessed as a member of the family member, it can also be accessed as a friend and friend. The AP needs to configure at least two SACs, one for the family member's SAC (SAC-Member); SAC (SAC-Friend) for relatives and friends.

In this application scenario, the implementation of differentiated charging is as shown in FIG. 4, and includes the following steps:

Step s401, AP configuration supporting Close admission mode SAC-Member and SAC-Friend

Step s402: The UE accesses the AP as a Friend.

Specifically, the RRC (Radio Resource Control) is established between the UE and the AP, and then the UE sends an Init Direct Transfer message to the AP, requesting to update the location area LA (LA Update Req).

Step s403: The UE successfully accesses the AP, and the AP selects the identity identifier for the UE as SAC-Friend.

Step s404: The AP fills in the SAC in the INITIAL UE MESSAGE as SAC-Friend, and sends it to the AG/CN on the network side, requesting to update the location area LA (LA Update Req).

Step s405: The core network sends a RANAP (Radio Access Network Application Part) Direct Transfer (RANAP) message to the AP, and accepts LA Update Accept.

Step s406: The AP sends an RRC Direct Transfer message to the UE, and accepts an update of the location area LA (LA Update Accept). In step s407, the uplink direct transmission message is filled in the SAC-Friend when the subsequent service is established, and the charging is performed according to the LAC and the SAC-Friend.

Specifically, according to the LAC carried in the message, the network side may determine that the UE is located in a macro coverage or an AP coverage, and then perform charging on the UE according to the corresponding macro network or the SAC-Friend charging standard under the AP.

In this way, different UEs have different SACs in the CDR bills generated by the AP. The family members use SAC-Member, and the relatives and friends use SAC-Friend. In the billing system, differentiated billing based on different SACs can be implemented. If you need to set up admission for others, for example, for the temporary guest guest, you need to configure another SAC, such as SAC-Guest, and the uplink direct message of the UE that will be accessed as the temporary guest guest. The SAC is filled in the SAC-Guest, and the CDR bill of the UE is charged by the SAC-Guest. In another application scenario, the API and AP2 belonging to a group are used as an example. The API and AP2 support the group admission mode. At least the SAC (GroupC-GroupC or SAC-GroupE, hereinafter referred to as SAC-Group) for the member Associator or Staffer is required to be configured on the API and AP2.

In this application scenario, the implementation of differentiated charging is as shown in FIG. 5, and includes the following steps:

Step s501: The API that supports the group admission mode and the AP2 configure the SAC-Group. Step s502: The UE of the Member identity in the API moves to the AP2, and accesses the AP2 by the member Associator.

Specifically, the UE establishes an RRC (Radio Resource Control) between the UE and the AP2, and then the UE sends an Init Direct Transfer message to the ,2 to request an update of the location area LA (LA Update Req).

Step s503: AP2 triggers the admission of the group. After the access is successful, AP2 selects SAC-GroupC for this UE. The group's access process requires network side involvement.

Step s504: The AP fills in the SAC in the INITIAL UE MESSAGE as the SAC-GroupC, and sends it to the AG/CN on the network side to request the update of the location area LA. ( LA Update Req ).

Step s505: The core network sends a RANAP (Radio Access Network Application Part) direct transfer (RANAP Direct Messaging) message to the AP, and accepts LA Update Accept.

Step s506: The AP sends an RRC Direct Transfer message to the UE, and accepts an update of the location area LA (LA Update Accept).

Step s507: The uplink direct transmission message is filled in the SAC-GroupC when the subsequent service is established, and the charging is performed according to the LAC and the SAC-GroupC.

In this way, different SAs have different SACs in the CDR bills generated by the AP. The members use SAC-GroupC to implement differentiated charging based on different SACs in the billing system. Since the AP in the group admission mode can also have local access, the AP itself can also set the member member, or the access list of the guest guest. At this time, the AP also needs to configure SAC-member and SAC-Guest. In this case, if a UE belongs to the Guest Admission List of an AP in the Group and belongs to the Group Admission List of the Group where the AP is located, the SAC-Guest is preferentially selected according to the AP priority. Admission, Admission is selected by SAC-Guest, and Group Admission is performed without AP local admission. In addition to the foregoing user equipment identity being SAC, the LAC may also be used as the user equipment identity. In this case, the use of the SAC identifier in the prior art has no effect. For example, the SAC can still be used for the positioning. Whether the SAC is carried in the message exchanged by the user equipment, the AP, and the network side is not affected by the LAC in the technical solution of this embodiment. .

In the embodiment in which the LAC is used as the user equipment identity, the specific implementation is similar to the foregoing embodiment in which the SAC is used as the user equipment identity. The difference is that the SAC is replaced by the LAC, that is, the APs in the same area are configured with two or Multiple LACs, each LAC is used for different UE identities, and all LACs corresponding to this UE identity use this LAC, core The two LACs seen by the network are physically the same area.

Take the network shown in Figure 6 as an example. For the UE with the membership of the Member, the AP selects the LAC as the LAC10 (LAC-Member) in all the upstream messages, and the other UEs (as the Guest) selects the LAC11 (LAC-Guest). By analogy, differentiated charging based on different LACs can be implemented in the billing system. The CDR bills are distinguished according to different LACs.

By using the method provided by the embodiment of the present invention, the corresponding user equipment identifier is selected for different user equipment identity, and differentiated charging requirements between different APs and different user equipments under the same AP are implemented, and the core network CN is The impact of the medium network element is small. In addition, through reasonable LAC and SAC configuration strategies, under the premise of meeting the positioning needs, avoiding more special requirements for network planning.
