Embodiment 1

[0172] Such as figure 2 As shown, when triggering the migration of the external agent FA entity, steps are included:

[0173] Step 1, triggering the migration of the external agent FA entity, the triggering reason is as above, and will not be repeated here;

[0174] Step 2, the serving access serving network gateway (Serving ASN-GW) of the user terminal MS requests the anchor access serving network gateway (Anchor ASN-GW) where the FA entity is located for the context information to be carried when the FA entity migrates;

[0175] The anchor ASN-GW informs the serving ASN-GW of the context information to be carried when the above FA entity migrates.

[0176] The process of step 2 of the present embodiment can also be:

[0177] The anchor access serving network gateway (Anchor ASN-GW) where the FA entity is located informs the serving access serving network gateway (Serving ASN-GW) of the user terminal MS of the context information to be carried when the above FA entity migr...

Embodiment 2

[0199] Such as image 3 As shown, when the authenticator migrates, steps are included:

[0200] Step 1, trigger the re-authentication and authorization process, including the situation triggered by the MS or the network side;

[0201] Step 2, if the re-authentication is initiated by the network side, it can be initiated by the Anchor Authenticator (Anchor Authenticator) or by the Serving GW (Serving GW), and finally notify the base station BS to inform the user terminal MS to initiate re-authentication through the air interface Authorization process, the step 2 is optional;

[0202] Step 3, carry out the re-authentication and authorization process, the specific signaling has been defined in the IEEE802.16d / e and WiMAX draft, and will not be repeated here;

[0203] Step 4, the serving ASN-GW sends a context request (Context-Request) message to the access service network gateway where the anchor authenticator (Anchor Authenticator) entity is located before migration;

[0204]...

Embodiment 3

[0222] Such as Figure 4 As shown, in the embodiment of the migration of the above-mentioned functional entity, the release of the IP address includes steps:

[0223] Step 1, the user terminal MS sends an IP address release (DHCP Release) message to the ASN-GW where the Dynamic Host Configuration Protocol agent or relay (DHCP Proxy / Relay) entity is located;

[0224] Step 6: The ASN-GW where the DHCP agent or relay entity is located sends an IP address release acknowledgment (DHCP-Ack) message to the user terminal.

[0225] Wherein, when the Dynamic Host Configuration Protocol server is located in the connection service network CSN, the steps may also be included:

[0226] After receiving the IP address release message, the ASN-GW where the Dynamic Host Configuration Protocol relay (DHCP Relay) entity is located sends the IP address release message to a Dynamic Host Configuration Protocol server (DHCPServer);

[0227] After receiving the IP address release message, the DHCP s...

Abstract

This invention provides a transfer method for functional entities in WiMAX network, in which, the functional entities include: an authenticator, a proxy mobile IP customer end, an outside proxy entity, a service flow authorization entity, a data channel function entity, a dynamic host configuration protocol proxy or a relay entity, a charge customer end and its proxy, and the transfer of the functional entities includes: setting up a binding relation among the functional entities, when the outside proxy entity is triggered or the authenticator transfers, other functional entities will transferalong with it according to the binding relation.

Description

technical field [0001] The invention relates to a WiMAX (Worldwide Interoperability for Microwave Access) network, in particular to a method for migrating functional entities in the WiMAX network. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX: Worldwide Interoperability for Microwave Access) network is a wireless metropolitan area network technology based on the IEEE 802.16 standard, such as figure 1 As shown, it mainly consists of three parts: [0003] The client is a mobile station (MS: Mobile Station) / terminal device (SS: SubscriberStation); [0004] Access Service Network (ASN: Access Service Network), including base station (BS: BaseStation) and access service network gateway (ASN GW: Access Service Network Gateway); [0005] Connectivity Service Network (CSN: Connectivity Service Network), including policy server (PF: Policy Function), authentication, authorization and accounting server (AAA Server: Authentica-tion, Authorizatio...
