Abstract: A Bloom filter generation method and apparatus is presented, where the method includes acquiring to-be-combined files, when a quantity of deletion records in the to-be-combined files falls within a false positive permission range, acquiring a Bloom filter of each to-be-combined file, where capacities of Bloom filters of different to-be-combined files are the same, and performing a bitwise OR operation on bit values at same locations in Bloom filters of the different to-be-combined files, in order to obtain a target Bloom filter and use the target Bloom filter as a Bloom filter of a combined file obtained by combining the different to-be-combined files, and hence an amount of calculation processing in Bloom filter generation is reduced, a system resource is reduced, and resource overheads are reduced.

Abstract: A mobile edge computing method and apparatus are provided. The method which is implemented by a mobile edge computing (MEC) management network element includes: receiving an MEC virtualization resource request sent by a control plane of a target radio access network (RAN), wherein the control plane belongs to the target RAN to which user equipment (UE) is handed over, and the MEC virtualization resource request includes an MEC computing resource requirement of the UE; creating, based on the MEC virtualization resource request, a new virtual machine (VM) on an MEC server for the UE, wherein the new VM is used on the target RAN side after the handover; and sending first information of the new VM to the control plane, wherein the first information includes an ID of the new VM. According to the application, the efficiency of usage of resources during a handover of UE is significantly improved.

Abstract: A communication method includes: sending a first public key and a signature of the first public key; receiving first information from a second node, where the first information includes an identification (ID) ciphertext; decrypting the ID ciphertext based on a first private key corresponding to the first public key, to obtain an ID of the second node; and sending second information to the second node, where the second information includes a temporary ID corresponding to the second node, and the temporary ID is used to temporarily indicate an identity of the second node.

Abstract: Embodiments of the present invention disclose a method, relay agent and system for acquiring an IP address in a network. According to the method, the relay agent configures multiple gateway IP addresses corresponding to a type of a client, adds the multiple gateway IP addresses to a DHCP Discover packet of the client, and sends the DHCP Discover packet to a DHCP server, so that the DHCP server allocates an IP address to the client, and sends a DHCP Offer packet to the client after determining that one gateway IP address in the multiple gateway IP addresses belongs to a same network segment as the allocated IP address, so that the DHCP server allocates the IP address to the client, thereby implementing that multiple IPs in different IP address segments are allocated to a same DHCP client type.

Abstract translation: 本发明的实施例公开了一种用于获取网络中的IP地址的方法，中继代理和系统。 根据该方法，中继代理配置与客户端类型相对应的多个网关IP地址，将多个网关IP地址添加到客户端的DHCP Discover数据包，并将DHCP Discover数据包发送到DHCP服务器， DHCP服务器为客户端分配IP地址，并在确定多个网关IP地址中的一个网关IP地址与分配的IP地址相同的网段后，向客户端发送DHCP Offer数据包，以便DHCP服务器分配 到客户端的IP地址，从而实现不同IP地址段中的多个IP被分配给相同的DHCP客户端类型。
