A communication method for communicating content having a content name from a mobile source node (409; 509; 611) to a content requester (401; 501; 601) in a content centric network that further comprises a first content router (405; 505; 605) and a second content router (407; 507; 607), said content centric network performing routing and/or delivery based on content names, the communication method comprising: the mobile source node determining whether the mobile source node (409; 509; 611) moves from a first domain including the first content router (405; 505; 605) to a second domain including the second content router (407; 507; 607); in response to determining that the mobile source node moves, the mobile source node transmitting to the first content router (405; 505; 605) via the second content router (407; 507; 607) a prefix registration message indicating that the mobile source node (409; 509; 611) moves; the first content router determining whether the prefix registration message is received; and the first content router partially updating routing information of the mobile source node (409; 509; 611) based on whether the prefix registration message is received; wherein the prefix registration message comprises prefix information including a name of the mobile source node (409; 509; 611) and signature information that identifies that the prefix registration message is transmitted by the mobile source node (409; 509; 611), the prefix registration message including prefix information about the domain that the mobile source node is currently located at, wherein the name of the mobile source node comprises said content name of said content; wherein the partially updating comprises determining whether a domain of the mobile source node (409; 509; 611) matches a domain of the first content router (405; 505; 605) based on the prefix registration message. the mobile source node determining whether the mobile source node (409; 509; 611) moves from a first domain including the first content router (405; 505; 605) to a second domain including the second content router (407; 507; 607); in response to determining that the mobile source node moves, the mobile source node transmitting to the first content router (405; 505; 605) via the second content router (407; 507; 607) a prefix registration message indicating that the mobile source node (409; 509; 611) moves; the first content router determining whether the prefix registration message is received; and the first content router partially updating routing information of the mobile source node (409; 509; 611) based on whether the prefix registration message is received; wherein the prefix registration message comprises prefix information including a name of the mobile source node (409; 509; 611) and signature information that identifies that the prefix registration message is transmitted by the mobile source node (409; 509; 611), the prefix registration message including prefix information about the domain that the mobile source node is currently located at, wherein the name of the mobile source node comprises said content name of said content; wherein the partially updating comprises determining whether a domain of the mobile source node (409; 509; 611) matches a domain of the first content router (405; 505; 605) based on the prefix registration message.
