Correspondingly, the invention further provides a WFAP and a device for selecting NAP. In the invention, the WFAP can determine the NAP supplying wireless resource for itself without dependence on macro network, and can provide wireless access service for the user.
Description
Technical field
The present invention relates to communication technical field, particularly a kind of method and apparatus of selecting Network Access Provider.
Background technology
Mobile communications network just is being devoted to for the user provides higher transmitted in packets ability, to satisfy the demand of mobile subscriber to the data service that increases fast.Mobile microwave based on IEEE 802.16 wireless access technologys inserts global-intercommunication (Worldwide Interoperability for Microwave Access, WiMAX) network, can therefore be subjected to paying close attention to widely for the user provides the high-speed data transmission ability.As the expansion of WiMAX access technology, mobile WiMAX network has increased the support to terminal mobility, makes portable terminal switch between the different radio access point and can keep business continuance when roaming, thereby satisfy the demand of commercial mobile communication business.
For providing the operator of service, the WiMAX network can be divided into Network Access Provider (NetworkAccess Provider, NAP) with Internet Service Provider (Network Service Provider, NSP), wherein NAP has radio spectrum resources, and realize the covering of wireless signal by setting up modes such as base station equipment, for providing, the user eats dishes without rice or wine to insert.NSP then has user's CAMEL-Subscription-Information, and provides Connection Service to Internet for the user by authentication.The user is connected to NSP by the wireless access that NAP provides, and is connected to Internet then.
In the rare area of population, the base station number that operator disposes is few, and area coverage is big, is difficult to penetrate thicker building wall, causes some users can't receive wireless signal well in the room.Cover the blind spot problem in order to solve similar mobile communication, the WiMAX system has introduced the notion of Home eNodeB Femtocell.By in the miniature Femtocell wireless base station of user's indoor deployment, can solve the problem of grand network coverage blind spot effectively, and reduce the load of eating dishes without rice or wine of grand network.Simultaneously, because Femtocell can be a few users service only, make these can obtain higher eat dishes without rice or wine speed and service quality, and might enjoy lower service rate by the user that Home eNodeB networks.
WiMAX home base station access point (WiMAX Femtocell access point, WFAP) insert Internet by the fixed network (as DSL) in the user family, after passing through the authentication of NSP, the Radio Resource of authorizing according to NAP (as frequency range etc.) open and eat dishes without rice or wine, for the domestic consumer provides wireless access.The user can enjoy the WiMAX service under WFAP, and can carry out seamless switching between WFAP and grand network base station.
Because WFAP is the subscriber equipment that belongs to a specific NSP, and NSP can set up commercial relations with a plurality of NAP, allows these NAP to provide the radio band resource for this WFAP.Therefore, WFAP need at first select a NAP to provide wireless resource configuration for oneself before providing wireless access for portable terminal, could open according to the Radio Resource of these mandates then and eat dishes without rice or wine.Still the WFAP that does nothing at present selects the method for NAP.
Summary of the invention
The embodiment of the invention provides a kind of method and apparatus of selecting Network Access Provider, makes WFAP not rely under the prerequisite of grand network, realizes the selection of NAP, for the user provides the wireless access service.
The embodiment of the invention provides a kind of method of selecting Network Access Provider, comprising:
WiMAX home base station access point WFAP sends Network Access Provider NAP request message to Internet Service Provider NSP;
WFAP receives the NAP response message that described NSP returns, and described NAP response message comprises the NAP information that described NSP determines;
WFAP connects according to the described NAP information and the NAP that receive.
The embodiment of the invention also provides a kind of WiMAX home base station access point WFAP, comprising:
Request unit is used for sending Network Access Provider NAP request message to Internet Service Provider NSP;
Receiving element is used to receive the NAP response message that described NSP returns, and described NAP response message comprises the NAP information that described NSP determines;
Connect and set up the unit, be used for connecting according to the described NAP information and the NAP that receive.
The embodiment of the invention also provides a kind of device of selecting Network Access Provider NAP, comprising:
Receiving element is used to receive the Network Access Provider NAP request message that WiMAX home base station access point WFAP sends;
Determining unit is used for determining NAP information;
Transmitting element is used for returning the NAP response message to described WFAP, and described NAP response message comprises the NAP information that described determining unit is determined.
The embodiment of the invention is by carrying the information that is used for determining NAP in the request message of issuing NSP at WFAP, select the information in information and the described request message to determine NAP by NSP according to local NAP, make that WFAP can be under the prerequisite that does not rely on grand network, be defined as oneself providing the NAP of Radio Resource, for the user provides the wireless access service.
