摘要： A method and a Packet data network GateWay (PGW) for releasing an Internet Protocol (IP) address in a mobile network are provided. The method includes allocating an Internet Protocol version 4 (IPv4) address and an Internet Protocol version 6 (IPv6) address to a User Equipment (UE) to activate a Packet Data Network (PDN) connection between the UE and the PGW; and if the UE releases the IPv4 address, transmitting to a Serving GateWay (SGW) a Binding Revocation message including an indication to release only the IPv4 address from the PDN connection to SGW.

摘要： One embodiment of the present invention provides a system that protects a server against denial-of-service attacks. During operation, the server receives a request for service from a client. Note that the client can be distinguished from other clients, for example, by its source IP address. In response to this request, the server sends a random number, y, and an identifier, id1, to the client, and allows the client to compute a preimage, x, such that y=h(x). Upon receiving an answer from the client including the preimage x and an identifier, id2, the server verifies that the identifier, id1, sent to the client matches the identifier, id2, received from the client. If the identifiers match, the server computes h(x), and compares h(x) against y. If h(x)=y, the server performs the requested service for the client. In this way, the server avoids computing h(x) until the server receives the answer with a matching identifier.
摘要翻译：本发明的一个实施例提供了一种保护服务器免受拒绝服务攻击的系统。在操作期间，服务器从客户端接收服务请求。请注意，客户端可以与其他客户端区分开来，例如，通过其源IP地址。响应于该请求，服务器向客户端发送随机数y和标识符id 1，并且允许客户机计算预图像x，使得y = h（ X）。在从客户端接收到包括预图像x和标识符id 2的解答的情况下，服务器验证发送给客户端的标识符id 1是否符合标识符， id <2> ，从客户端收到。如果标识符匹配，则服务器计算h（x），并将h（x）与y进行比较。如果h（x）= y，则服务器为客户端执行所请求的服务。以这种方式，服务器避免计算h（x），直到服务器接收到具有匹配标识符的答案。

摘要： A method and system for releasing an Internet Protocol (IP) version 4 address using a Dynamic Host Configuration Protocol (DHCP) release in a Proxy Mobile IP version 6 (PMIPv6) of a third Generation Partnership Project (3GPP) Evolved Packet Core (EPC). The method includes transmitting a DHCP release request from a Serving GateWay (SGW) to a Packet Data Network (PDN) GW, transmitting a binding revocation from the PDN GW to the SGW, acknowledging the binding revocation from the SGW to the PDN GW, and deleting the IP version 4 connection for an active PDN connection.

摘要： A method and apparatus are provided for producing a decorated networking identifier at a client terminal for transmission to a server side element. The networking identifier is obtained at the client terminal. The networking identifier is appended with one or more extensible decorations at the client terminal creating the decorated networking identifier. The one or more extensible decorations are separated from the networking identifier by a first predetermined character. The one or more decorations each include a decoration sequence and an identifier corresponding to the decoration sequence. The identifier and the decoration sequence are separated by a second predetermined character. The decorated networking identifier is transmitted from the client terminal to the server side element.
