Abstract: A method, an apparatus, and a system for implementing User Equipment (UE) handover are disclosed. A Mobility Management Entity (MME) obtains address information of a serving Interworking Function (IWF) by interacting with a function entity in a network and notifies the IWF to process handover according to the obtained IWF address information, so that the MME is capable of obtaining the address information of the serving IWF. Therefore, the normal proceeding of a UE handover procedure in a Circuit Switched over Packet Switched (CSoEPS) scenario is ensured.

Abstract: A first message is sent by an MSC/VLR and it is determined that a user equipment is in an abnormal state according to the first message. A second message is sent to the user equipment. The second message is used to instruct the user equipment to initiate attachment to the MSC/VLR. An apparatus includes a receiving module, a first determining module and a sending module.

Abstract: A method and device for detaching a user equipment (UE) are disclosed in the present invention. The UE is registered with a mobility management entity (MME) in a packet switched (PS) network and a mobile switching center (MSC) in a circuit switched (CS) network. When the UE needs to detach from the PS network, the MSC receives a Detach Request with a Detach Type indicating the detaching from the PS network only; after receiving the Detach Request, the MSC deletes the context of the PS core network entity and clears the connection between the MSC and the MME. An MME for performing UE detachment is also disclosed in the present invention. The present invention helps reduce the time delay during the subsequent handover and quickly provide users with communications services, so as to improve user's experience and meet the carriers' requirements.

Abstract: A method for heterogeneous addressing mapping is provided according to the embodiments of the present invention. The method includes: assigning, by an Interworking Function entity (IWF), a first identification or a first address to a Diameter protocol node; mapping a received Diameter protocol message sent from the Diameter protocol node into a Mobile Application Part (MAP) protocol message, and sending the mapped MAP protocol message to an MAP protocol node using the first address assigned by the IWF as a source address or using the first identification assigned by the IWF as a source identification. The present invention also provides a system and an apparatus for heterogeneous addressing mapping. According to the embodiments of the present invention, when the Diameter node is communicating with the MAP node via the Interworking Function entity, the method for mapping the node identification for each other as well as the addressing relationship corresponding to each identification are provided.

Abstract: A target mobility management network element receives a forward relocation request message sent by a source mobility management network element, where the forward relocation request message includes single radio voice call continuity SRVCC capability information; and the target mobility management network element sends, to an target access network element, a first request message that carries information of SRVCC operation possible.

Abstract: The present invention discloses for the ability for processing circuit switched (CS) services in an evolved packet network. For example, embodiments provide a method that includes: by a mobility management entity (MME), receiving a mobile terminated (MT) service indication from a mobile switching center (MSC); sending the MT service indication to user equipment (UE); and receiving an MT service response returned by the UE and performing subsequent operations according to the MT service response. In the method of the present invention, when an MT service arrives, the MME does not trigger the evolved NodeB (eNodeB) to hand over the packet switched (PS) services of the UE but notifies the UE of the MT service and performs subsequent operations according to the MT service response returned by the UE, thus avoiding the waste of network resources caused by a meaningless handover of PS services.

Abstract: A method for acquiring information includes: receiving an Internet Protocol (IP) address acquisition request or Packet Data Network (PDN) address allocation information sent by User Equipment (UE); determining a PDN address capability according to the IP address acquisition request or the PDN address allocation information; and sending the determined PDN address capability to the UE. An UE and network equipment are also provided.
