Method and device for implementing dynamic groups

A system for implementing dynamic groups, comprising:

• a Home Location Register (HLR);
• and
• a Personal Information Management (PIM) server;
• wherein the HLR is adapted to generate a roam notification message of a roaming user, and send the roam notification message to the PIM server, and wherein the roam notification message carries location information, and
• wherein the PIM server is adapted to receive a roam notification message, resolve location information of the roaming user from the roam notification message, find pal information that matches the location information of the roaming user from an address book of the roaming user, and create a group according to the pal information.

A system for implementing dynamic groups, comprising:

• a Home Location Register (HLR);
• and
• a user terminal;
• wherein the HLR is adapted to generate a roam notification message of a roaming user, and send the roam notification message to the user terminal, and wherein the roam notification message carries location information;
• and
• wherein the user terminal is adapted to receive a roam notification message, resolve location information of the roaming user from the roam notification message, find pal information that matches the location information of the roaming user from an address book of the roaming user, and create a group according to the pal information.

A computer readable media, embodying computer executable instructions for implementing dynamic groups, which, when executed by a machine, is operable to cause the machine to perform a method comprising:

• receiving a roam notification message of a roaming user, wherein the roam notification message carries location information;
• finding, from an address book of the roaming user, pal information that matches the location information carried in the roam notification message;
• and
• creating a group according to the pal information.
