Packet call processing involving packet-based data transfers in a mobile communications system can handle a packet call if the mobile station has the ability to accommodate the packet call even when packet call collision occurs. Upon detecting a packet call collision between a first received packet call and a second received packet call, the mobile station determines whether a Network Service Access Point Identifier (NSAPI) is available and can be allocated to handle the second received packet call. Thus, an increased number of packet calls can be processed simultaneously by the network and / or the mobile station so that Internet-based applications, as well as other high-speed data applications can be handled more effectively and efficiently. Such packet call collision detection and NSAPI allocation techniques are applicable to various wireless and / or mobile communications environments, such as GPRS, UTMS, etc. involving data packet transmissions whereby packet call collisions may occur. <IMAGE>

It avoids path overlap between the original flow and the redundant flow; and allocates different numbers of redundant flows to short flows of different sizes. The equal-cost path utilization is reasonable, and it is more efficient, easy to deploy, and low in load.

The invention discloses a call collision processing method, a terminal and a transfer platform. The method comprises the following steps: sending an access request to the transfer platform by the terminal, wherein the access request includes access request emergencies with the preset number; monitoring the channel state of the transfer platform by the terminal to judge whether the transfer platform transfers the access request emergencies of the terminal in a preset monitoring time, if the access request emergencies of the terminal are transferred for at least two times, sending a following emergency to the transfer platform by the terminal, if the access request emergencies of other terminals are continuously transferred for at least two times, terminating the operation of sending the following emergency to the transfer platform by the terminal. Due to the adoption of the technical scheme, the call collision among a plurality of terminals can be solved.

The invention provides a call handling method, a call handling device, a call handling system and an audio gateway. The method comprises the following steps: after receiving first ring transmitted when a calling terminal initiates a call, setting the state of a passage corresponding to a passage number as an occupied state; and establishing the call between the calling terminal and a called terminal through the passage. The device comprises a foreign exchange office and a passage management device; the foreign exchange office comprises a setting triggering module and a call module; and the passage management device comprises a setting module, wherein the setting triggering module is used for triggering the setting module to set the state of the passage corresponding to the call as the occupied state after receiving the first ring transmitted when the calling terminal initiates the call; and the call module is used for establishing the call between the calling terminal and the called terminal through the passage.
