Systems and methods for locating a cellular phone are provided. More particularly, systems and methods for providing the location of a requested user's cellular phone from a requesting user's device (e.g., a second cellular phone) based on access rights defined by the requested user. Location descriptions may be provided at a multitude of levels. For example, if a cellular phone, or an identity associated to (e.g., logged into) a cellular phone, has been given access rights to a cell phone's exact location for an indefinite amount of time, that cell phone can receive, on command, the exact location of the approved cell phone. Other levels of location information that can be granted include, for example, proximities, states, and countries.

A method, an apparatus, and a system for migrating a virtual network function instance, where the method includes starting a signaling message migration operation before or when running status information replication is started such that signaling message migration can also be performed synchronously with running status information replication during migration of a virtual network function instance. Because signaling message migration and running status information replication occur simultaneously, new running status information created after migration and changed running status information can be synchronized by signaling message migration. Therefore, an amount of replicated running status information is reduced, migration efficiency of a virtual network function instance is improved, a backup virtual network function can take over a faulty virtual network function as quickly as possible, and fault recovery efficiency is improved.

A network, and a method of operating a network. The network includes a plurality of stations each able to transmit and receive data so that the network can transmit data between stations via at least one selected intermediate station. Each station transmits probe signals in broadcast fashion to other stations to gather a list of neighbor stations. The stations transmit position data and/or position determining data in at least some of the probe signals. Each station maintains position data and/or position determining data received from selected probing stations, and utilizes the data to determine the absolute or relative position of itself and/or other stations. The stations can determine the relative or absolute position of other stations in direct communication with themselves, and also of other stations not in direct communication with themselves.

A method and device for indicating the number of bits are provided. In the method, a transmitting User Equipment (UE) and/or a network entity indicate the number k of effective indication bits in a bitmap sequence, the bitmap sequence indicates Physical Sidelink Shared Channel (PSSCH) subframes allocation, k includes one or multiple values, 1≦k≦N, and N is a bit length of the entire bitmap sequence.

The embodiments of the present disclosure disclose a Device to Device communication method and system based on network sharing, and a storage medium. The method includes that: Device to Device User Equipment D2D UE receives at least one of the following information sent by a network through a broadcast message or a dedicated message: a list of different Public Land Mobile Networks PLMNs supporting D2D, resource pool information for D2D discovery and/or D2D communication of different PLMNs, and a PLMN list corresponding to the resource pool information for D2D discovery and/or D2D communication; and a resource range used for D2D discovery and/or D2D communication is determined by virtue of the resource pool information or the resource pool information corresponding to the PLMN list.

A stable virtual access point and a method for operating a stable virtual access point are disclosed. In embodiments a method for operating a logical endpoint of a stable virtual access point, wherein the logical endpoint includes an interface with a macro access point, wherein the stable virtual access point comprises a plurality of transmission points (TPs), and wherein the TPs provide a coordinated data transmission to a UE comprises storing, at the logical endpoint, a connection status of the UE, receiving, at the logical endpoint, information regarding the connection status of the UE from the macro access point, determining, at the logical endpoint, a change in the connection status of the UE and updating, at the logical endpoint, the connection status of the UE with respect to the change.

The present invention provides an access control method, a base station, user equipment, and a mobility management entity, where the access control method includes: receiving, by the base station, a temporary identifier and a PLMN available indication that are of the UE and sent by the UE; receiving a service request message sent by the UE, and determining a serving MME of the UE according to a GMMEI in the temporary identifier of the UE; and sending the service request message and the PLMN available indication to the serving MME of the UE, so that the serving MME of the UE sends a redirection indication, and the UE registers with an HPLMN of the UE. Therefore, in a network sharing scenario, the UE can select the home PLMN of the UE as a serving PLMN of the UE as early as possible.
