[0021] figure 1 It is a flowchart of a method for network switching between WiMAX and 3GPP Pre-R8 dual-mode terminals according to the first embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0022] Step S102, using the interworking function module to transfer the IP address of the terminal between WiMAX and the 3GPP Pre-R8 network;

[0023] Step S104: According to the IP address, the terminal switches between WiMAX and 3GPP Pre-R8 networks.

[0024] The network switching method for WiMAX and 3GPP Pre-R8 dual-mode terminals according to the embodiment of the present invention transfers the IP address of the terminal between WiMAX and 3GPP Pre-R8 networks, so that the terminal has the same IP address before and after the switch, thereby The technical effect of ensuring the continuity of terminal packet services and improving user experience is realized.

[0069] In step 401, the UE is initially connected to the WiMAX network and has an IP address allocated by IWK. Data is transmitted through WiMAX network;

[0070] Step 402: When the 3GPP Pre-Rel8 network is available, the BS makes a decision based on the wireless signal and other conditions to trigger the MS to perform handover to the 3GPP Pre-Rel8 network;

[0071] Step 403: The terminal initiates an attach request message to the SGSN, which carries the IMSI of the MS;

[0072] Step 404, the SGSN interacts with the HLR / HSS to authenticate the user terminal;

[0073] Step 405, the SGSN executes the location update process. SGSN saves the user data inserted by HSS / HLR, which contains the IWK address;

[0084] Figure 5 It is a flowchart of a handover method for WiMAX and 3GPP Pre-R8 dual-mode terminals from a 3GPP Pre-R8 network to a WiMAX network according to the third embodiment of the present invention. Such as Figure 5 As shown, the method includes the following steps:

[0085] Step 501: The UE is initially connected to the 3GPP Pre-R8 network and has an IP address allocated by IWK;

[0086] Step 502: When the WiMAX network is available, the UE makes a decision based on wireless signals and other conditions, and decides to perform handover to the WiMAX network;

[0087] Step 503: The UE executes the WiMAX network access process and establishes a WiMAX connection with the BS;

[0088] Step 504: The UE connects to the AAA server through the ASN-GW of the WiMAX network, and authenticates and authorizes the user terminal. During the access authentication process, AAA interacts with HSS / HLR to obtain the IP address of the IWK cached in HSS / HLR and returns it to ASN-GW during the au...

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a network switching method and system for WiMAX and 3GPP Pre-R8 dual-mode terminals. Background technique [0002] WiMAX (World Interoperability for Microwave Access) is a broadband wireless access technology based on the IEEE 802.16 standard, which can effectively utilize limited wireless spectrum resources and provide a larger air interface bandwidth (up to 70Mbps data transmission) Capabilities), with application scenarios including fixed, nomadic, portable, mobile, etc. [0003] The 3GPP Pre-R8 (3rd Generation Partnership Project, third generation partnership project) network is a relatively mature service network deployed by current operators, and it is also an infrastructure for future network development. [0004] In the process of implementing the present invention, the inventor found that when a dual-mode terminal supporting WiMAX and 3GPP Pre-R8 networks is switched between...
