The invention discloses an increment time slice adjustment framework and method in a CREDIT scheduler. An interrupt decision making information maintaining device is responsible for maintaining history interrupt decision making information, and an increment time slice adaptive adjustment device collects data information maintained in the interrupt decision making information maintaining device in a timing mode, adjusts history information in cooperation with an increment time slice and dynamically calculates a new increment time slice. If the newly-calculated increment time slice is different from the original increment time slice, the CREDIT scheduler is informed to update the increment time slice. As an extension of an original time slice mechanism, the increment time slice dynamically maintains a non-negative value to increase the length of the original time slice. The increment time slice mechanism is built on a virtual interrupt independent decision making mechanism, and therefore the length of the time slice can be increased on the premise that the I/O performance of a virtual machine is not influenced.

The invention discloses an inter-domain communication method of a distributed IMS (multimedia subsystem) core net framework. The inter-domain communication method comprises the following steps of: P-CSCF (proxy call session control function) of a distributed IMS core net receives a request of a user, and judges whether the type of the request is a login request or a conversation request; if the type of the request is the conversation request, the P-CSCF judges whether the user which initiates the login request is logined according to the self-stored user login information, if so, the P-CSCF obtains the login information of the user initiating the conversation request on the P-CSCF, the request is forwarded to the S-CSCF(serving-call session control function) logon by the user according to routing information in the request, and the S-CSCF logon by the user processes the conversation request according to the ascription area of a called user. The method provided by the invention is provided based on an area communication standard given by a 3GPP (the 3rd Generation Partnership Project) standard, and can guarantee that the distributed IMS core net which adopts a P2P distributed IMS core net has practical allocation and transport operation values.
