摘要： A call loop avoidance capability is provided for preventing formation of a call loop resulting from handling of a mobile terminated (MT) call in parallel with a location update for a mobile device (MD) in a wireless communication network. The call loop avoidance capability prevents formation of a call loop between an old mobility and call management entity (MCME) and a new MCME when delivery of an MT call to an MD is performed while the MD is in the process of moving from the old MCME to the new MCME using a location update procedure. An enhanced call routing procedure supports direct delivery of the MT call from the new MCME to the MD (rather than delivery of the MT call by the new MCME to the MD via the old MCME) in order to prevent formation of a call loop between the old MCME and the new MCME.
摘要翻译：提供呼叫循环回避能力，用于防止由无线通信网络中的移动设备（MD）的位置更新并行地处理移动终止（MT）呼叫而导致的呼叫环路的形成。呼叫循环回避能力防止在MD移动到旧的MCME的过程中执行在向MD的MT呼叫的传送时，在旧的移动性和呼叫管理实体（MCME）和新的MCME之间形成呼叫循环使用位置更新程序到新MCME。增强的呼叫路由过程支持从新MCME到MD的MT呼叫的直接传递（而不是通过旧的MCME将新的MCME的MT呼叫传送到MD），以防止在呼叫循环之间形成旧的MCME和新的MCME。

摘要： A method and apparatus for delivering a mobile terminated call to user equipment (UE) in a circuit switched fall back (CSFB) capable wireless network system using prepaging. When the visiting mobile switching center (VMSC) registered in the home location register (HLR) of the called UE receives a provide roaming message (PRN) from the HLR indicating that a CS call to the UE has been originated at a gateway mobile switching center (GMSC), the VMSC starts a paging process with a mobility management entity (MME) then returns a mobile station roaming number (MSRN) to the HLR when it receives a SGs service request indicating that the called UE is in EMM-connected mode. Alternatively, the VMSC sets a guard timer in response to the SGs service request and returns the MSRN to the HLR when the guard timer expires. In the meantime, the VMSC remain in a paging stage waiting for the response from the UE falling back to the UMTS/GSM network from the LTE network.

摘要： As a mobile device moves from one location area to another, the mobile device detects the different location identifiers broadcast by the wireless network(s) in those locations areas. The mobile device stores the location identifier for the last location area in which the mobile device was located. By comparing a received location identifier to the stored location identifier, the mobile device determines if the mobile device has entered a new location area. If so, the mobile device sends a location update request. In one embodiment, if the location update request is for a location area to which access by the mobile device is restricted, the network sends a communication to the mobile device that triggers the mobile device to update a location identifier stored at the mobile device to the location identifier for the restricted location area so that the mobile can update the network after entering/selecting a different location area.
摘要翻译：随着移动设备从一个位置区域移动到另一个位置区域，移动设备检测由那些位置区域中的无线网络广播的不同位置标识符。移动设备存储移动设备所在的最后位置区域的位置标识符。通过将接收到的位置标识符与存储的位置标识符进行比较，移动设备确定移动设备是否已经进入新的位置区域。如果是，则移动设备发送位置更新请求。在一个实施例中，如果位置更新请求是针对移动设备的访问受到限制的位置区域，则网络向触摸移动设备的移动设备发送通信，以将存储在移动设备处的位置标识符更新为用于受限位置区域的位置标识符，使得移动台可以在进入/选择不同位置区域之后更新网络。

摘要： A mobile terminated call is delivered to a mobile device during an inter- VLR location update by first routing the mobile terminated call to the old mobile switching center/visitor location register (MSC/VLR), determining that the mobile device is performing a location update to a new MSC/VLR at the old MSC/VLR, and then routing the mobile terminated call to the new MSC/VLR directly from the old MSC/VLR or via the gateway mobile switching center (GMSC) for connection of the mobile terminated call to the mobile device.

摘要： A method for delivering a mobile terminated call to a mobile device communicating with a mobile switching center (MSC) in one example comprises steps of attempting to deliver the mobile terminated call to a mobile device, receiving a message that the mobile device is no longer in the location area served by the visiting MSC and forwarding the mobile terminated call to a different visiting MSC. The mobile terminated call is forwarded directly from one VMSC to another VMSC without requiring two potentially international calls to be placed serially from the GMSC to a VMSC. This method of Mobile Termination Roaming Forwarding can reduce substantial delay in call setup while saving network resources during establishment of the first call.
摘要翻译：在一个示例中，用于将与移动交换中心（MSC）通信的移动终端呼叫递送到移动终端呼叫的方法包括以下步骤：尝试将移动终止的呼叫传送到移动设备，接收移动设备不再处于由访问MSC服务的位置区域并将移动终止的呼叫转发到不同的访问MSC。移动终端呼叫直接从一个VMSC转发到另一个VMSC，而不需要将两个潜在的国际呼叫从GMSC串行放置到VMSC。这种移动终端漫游转发方法可以在建立第一个呼叫期间节省网络资源，减少呼叫建立的实质性延迟。

摘要： An example method for inter-Mobile Switching Center (MSC) handover of a mobile device includes requesting, by an anchor MSC subsequent to sending a Mobile Application Part (MAP) Prepare Handover message, the International Mobile Equipment Identity and Software Version Number (IMEISV) from the mobile device. The anchor MSC receives the IMEISV of the mobile device in response to the requesting and forwards the IMEISV and/or a corresponding UESBI-Iu in a message to a target MSC. The MAP Prepare Handover message may have been forwarded without the IMEISV of the mobile device when such IMEISV was not yet available at the time the inter-MSC handover was initiated. The IMEISV and/or corresponding User Equipment Specific Behaviour Information (UESBI)-Iu may be forwarded in new Information Elements (IEs) in a MAP Forward Access Signaling (FAS) message to the target MSC

摘要： A method for facilitating inter-PLMN (Public Land Mobile Network) roaming comprises a plurality of operations. A home PLMN of a caller's wireless communication device performs an operation for determining that the caller's wireless communication device is not located in the home PLMN and, in response to determining that the caller's wireless communication device is not located in the home PLMN, an operation for facilitating a call routing service in a Service Control Point (SCP) of the home PLMN. The call routing service causes a call originated by the caller's wireless communication device while roaming in a visited PLMN to be routed back to a Gateway Mobile Switching Center (GMSC) of the home PLMN thereby allowing the home PLMN to have control over the roaming caller originated call and to have limited dependency on the visited PLMN.

摘要： Paging of a mobile device within a mobile pool area serviced by two or more mobile switching nodes is reduced using logical paging areas. The mobile pool area includes a plurality of location areas, each serviced by the two or more switching nodes. In addition, the mobile pool area is divided into multiple logical paging areas, in which each logical paging area includes at least two location areas. Upon receiving a mobile terminated call for the mobile device, if the location area of the mobile device is unknown, the logical paging area within which the mobile device is located is determined in order to page the mobile device and deliver the mobile terminated call to the mobile device.
