Managing contact groups from subset of user contacts

A method comprising:

• identifying a subset of contacts associated with a user of a mobile telecommunications device, wherein the subset of user contacts includes a portion of contacts accessible by the mobile telecommunications device and wherein the subset of contacts includes a plurality of contacts;
• determining at least two contact groups from the identified subset of contacts, wherein membership of one or more members in each of the at least two contact groups is automatically determined from the identified subset of contacts based on information maintained in a data store, the information including a context of the user and a plurality of user communication events associated with the context of the user, and wherein each contact of the identified subset of contacts is determined to be a member of at least one of the two contact groups;
• storing information associated with formation of the at least two contact groups in the data store;
• automatically determining a current context of the user of the mobile telecommunications device;
• comparing the current context of the user with the stored information associated with the formation of the at least two contact groups in the data store;
• and
• causing the generation of a contact display on the mobile telecommunications device, wherein the contact display includes a representation of a first contact group and a first contact group identifier, the first contact group for display on the mobile telecommunications device automatically selected from the at least two contact groups stored in the data store based on the current context of the user,
• wherein the method is implemented by a computing system.

A system comprising:

• a data store for maintaining subsets of contacts, wherein each subset of contacts is associated with a user of a mobile telecommunications device, wherein each subset of contacts includes a portion of contacts accessible by the respective mobile telecommunications device, and wherein the portion of contacts includes a plurality of contacts;
• and
• at least one computing device in communication with the data store, the at least one computing device configured to:
• identify a subset of contacts associated with a user of the mobile telecommunications device;
• determine at least two contact groups from the identified subset of contacts, wherein membership of one or more members in each of the at least two contact groups is automatically determined from the identified subset of contacts based on information maintained in the data store, the information including at least a context of the user and a plurality of user communication events associated with the context of the user, and wherein each contact of the identified subset of contacts is determined to be a member of at least one of the at least two contact groups;
• store information associated with formation of the at least two contact groups in the data store;
• automatically determine a current context of the user of the mobile telecommunications device;
• compare the current context of the user with the stored information associated with the formation of the at least two contact groups in the data store;
• and
• cause the generation of a contact display on the mobile telecommunications device, wherein the contact display includes a representation of a first contact group from the at least two contact groups and a first contact group identifier, the first contact group for display on the mobile telecommunications device automatically selected from the at least two contact groups stored in the data store based on the current context of the user.
