Patent ID: 8732243

Claim:
A method for application layer link control, comprising the following steps: judging whether the number “a” of links which have been established between an exterior internet protocol (IP) entity and a multimedia messaging service gateway (MMSG) in current granularity is less than a threshold number “A” of links for establishing a connection with the MMSG in the current granularity; when it is determined to be “yes”, subtracting the “a” from the “A” to obtain a threshold number “B” of links for establishing a connection with the MMSG in a next granularity, wherein B=A−a; and otherwise, obtaining that the threshold number “B” of links for establishing a connection with the MMSG in the next granularity equals 0, and rejecting a request that the exterior IP entity initiates to establish a connection with the MMSG in the next granularity, wherein the “a” is the sum of the number of links which have been established between the exterior IP entity and each service processor forming the MMSG respectively, and wherein the “A” is a preset threshold number of links for establishing a connection between the exterior IP entity and the MMSG in a previous granularity.
