[0109] The first embodiment provided by the present invention, such as figure 2 shown, including:
[0110] Step 101. Establish a buffer in the source ASN-GW.
[0111] This process specifically includes two situations.
[0112] One is: according to the QoS requirement of the service and / or the level of the user, statically establish a buffer in the source ASN-GW.
[0113] The second is: when an ASN-GW switch occurs, a buffer is dynamically established in the source ASN-GW according to the QoS requirement of the service and / or the class of the user. Specifically, this process includes:
[0114] Step 1: When the source BS negotiates with the MSS to trigger the handover, the source ASN-GW is notified by sending a handover message;
[0115] Step 2. When the source ASN-GW receives the handover message, dynamically establish a buffer in the source ASN-GW according to the QoS requirement of the service and / or user level.
[0116] When the MSS moves from the source BS to the rang...

[0154] The third embodiment provided by the present invention includes:
[0155] Step 301, establishing a buffer in the source BS.
[0156] This process specifically includes two situations.
[0157] One is: according to the QoS requirement of the service and / or the class of the user, a buffer is statically established in the source BS.
[0158] The second is: when handover occurs, a buffer is dynamically established in the source BS according to the QoS requirement of the service and / or the class of the user. Specifically, this process includes:
[0159] Step 1, the source BS negotiates with the MSS to trigger handover;
[0160] Step 2: After the negotiation between the source BS and the MSS is completed, a buffer is dynamically established in the source BS according to the QoS requirement of the service and / or the class of the user.
[0161] When the MSS moves from the source BS to the range covered by the target BS, or in the range covered by the source BS and the targe...
