摘要： In some examples, a method in a core network communicatively connected with a first radio access network (RAN) comprising a first network element, and a second RAN comprising a second network element, includes receiving a first Non Access Stratum (NAS) message via the second network element from a User Equipment (UE), where the UE has, with the first network element, a selected IP traffic offload (SIPTO) PDN connection. The mobility management node detects that the UE is connected to the second network element that is different from the first network element that has a first identifying characteristic, where the detecting comprises determining that the first NAS message is received with a second identifying characteristic of the second network element different from the first identifying characteristic associated with the SIPTO PDN connection.

摘要： A method, system and device are provided for managing LIPA and/or SIPTO connection releases when UE moves out of residential/enterprise network coverage in case service continuity is not supported for the LIPA/SIPTO PDN connection(s). To address problems caused by not providing service continuity for LIPA/SIPTO PDN connections, the PDN connection/PDP context created in the HeNB/HNB by the MME/SGSN includes context information related to the UE indicating whether such connection is a LIPA PDN connection PDN connection or not. In addition, each UE may be configured to reconnect or not reconnect to the PDN corresponding to a certain APN or service, depending on how the PDN connection was disconnected by the network.

摘要： In some examples, a user equipment (UE) obtains a connectivity in a first cell, the connectivity identified by an access point name (APN), where the APN corresponds to a first type of connection, and where the first type of connection provides access to services in a local data network. The UE camps on a second cell, determines if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising information of the second cell, and in response to determining that the connectivity is not supported in the second cell, disconnect the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message via the second cell.

摘要： Methods and apparatus for voice domain operation are described herein. One example method includes determining that an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) network is not preferred for voice service based on receiving a response message to a NAS message via the E-UTRA network, wherein the response message to the Non-Access Stratum (NAS) message comprises an indication that no voice service is available, storing an identification of a first public land mobile network (PLMN), wherein the first PLMN is associated with the E-UTRA network that is not preferred for voice service, and avoiding selection of a second PLMN's E-UTRA network when an identification of the second PLMN matches the identification of the first PLMN.

摘要： A mobility management node in A core network receives a first Non Access Stratum (NAS) message via a second network element from a user equipment (UE), wherein the mobility management node stores a first identifying characteristic associated with at least one of a Local IP Access (LIPA) packet data network (PDN) connection or a selected IP traffic offload (SIPTO) PDN connection, the at least one of the LIPA PDN connection or the SIPTO PDN connection being via a first network element and for the UE. The mobility management node detects that the UE is connected to the second network element that is different from the first network element that has the first identifying characteristic, and in response to a condition that each PDN connection of the UE is a LIPA PDN connection or a SIPTO PDN connection, sends a second NAS message, the second NAS message including a cause code with a value that represents “No EPS Bearer Context Activated.”
