Abstract:
1. A method for user-management in a presence system, said presence system comprises multiple presence servers communicating through a network, said method comprising: a combining step, in which multiple user sets, each comprising a plurality of users, that have a greatest correlation are combined into a user set to be allocated; and an allocating step, in which said user set to be allocated is allocated, for registration of said plurality of users in said user set to be allocated, to one presence server that can contain said user set among the multiple presence servers, wherein said combining step comprises: a merging step, in which two user sets that have a greatest correlation are merged into one user set; a selecting step, in which a current largest user set is selected; a comparing step for comparing a number of users in said current largest user set with a pre-defined threshold; repeating said merging and selecting steps until a number of users in said current largest user set is larger than the pre-defined threshold, if the number of users in said current largest user set is less than or equal to the pre-defined threshold; and a determining step, in which said current largest user set is treated as said user set to be allocated.
