摘要： A telecommunications system and method is disclosed for utilizing an Internet telephony system to perform a handover of a call between different types of systems. When a serving mobile switching center (MSC) determines that there is not another MSC belonging to the same type of wireless system to which a handover can be performed, the serving MSC sends a message to an Internet Gatekeeper via an Internet Gateway for the serving MSC, inquiring whether there are any other types of wireless systems nearby. The Internet Gatekeeper maintains a database of all existing wireless systems within the area served by the Internet Gatekeeper. The Internet Gatekeeper chooses a target MSC of another wireless system (if possible), and transmits the identity of this target MSC back to the currently serving MSC. Thereafter, the currently serving MSC performs the handover to the target MSC by routing signaling messages through the Internet Gateway and the Internet Gatekeeper to the target MSC.

摘要： A telecommunications system and method is disclosed for defining location-based group services, which can be implemented within a Group Call Services (GCS) node associated with a cellular network. When a group call is initiated, the GCS can send a positioning request to a Mobile Location Center (MLC) to locate the group members within a specified area. The particular location can be defined by the group number or the location can be prompted by the GCS. For each group member, the position of a mobile terminal associated with that group member is determined and the call is set up only to those members which the meet the specified area criteria. If none can be located within the specified area, the area can be expanded at the callers request.

摘要： A telecommunications system and method is disclosed for providing a substantially immediate electronic receipt after a consumer has made a purchase. When a consumer makes a purchase, the sales terminal, which is attached with a short message/e-mail sending capable terminal, can generate and route a short message along with the detailed purchase information to a transport address or alias address associated with the consumer via a Gatekeeper for the Internet for the area that the sales terminal is located in. Upon receipt of the short message, the Gatekeeper can then convert the alias address to the transport address, if the alias address is given and the consumer does not want the short message sent to the alias address, and forward the short message through the Internet to that transport address (or alias address) as an Internet Protocol datagram for storage and retrieval of the short message by the consumer either immediately or at a later time.

摘要： A base station in a wireless communication network saves connection information that enables it to recognize currently authenticated mobile stations. The base station carries out localized connection management processing for authenticated mobile stations, at least for certain types of packet data connection events. By carrying out localized processing, the base station skips the connection management signaling between it and a supporting mobile switching center that would otherwise be required for processing such events. Thus, in a cdma2000 base station embodying such localized processing, the MSC's involvement in packet data connection state transitions, short data burst deliveries, etc., can be eliminated or at least greatly reduced, thereby minimizing the MSC's role in supporting packet data services. In conjunction with localized processing, the base station still may require MSC-based re-authentication by individual mobile stations according to some timed schedule, or according to some form of packet data activity monitoring.

摘要： A service based Ringback Tone service that may be personalized by a calling party instead of a called party. The calling party generates and stores an originating profile that contains Ringback Tones or Ringback messages associated with a Ringback Tone subscriber (called party). When the calling party contacts the called party, the Ringback Tone chosen by the calling party and associated with the called party is then sent to the calling party until the calling party answers the call.

摘要： A system and method is disclosed for improved session management when roaming between access networks (AN) within a data cellular network. In one embodiment, gateway functionality is added to one AN in each subnet. The Gateway AN (GAN) provides session transfer capabilities during a dormant handoff with a source AN located in a different subnet. The GAN is responsible for receiving session information request messages from target AN's within the local subnet, querying other GANs within other subnets to locate the subnet that contains the source AN for the session and routing the session information back to the target ANs. In another embodiment, an extended session is established across several ANs within a subnet. When an Access Terminal (AT) initiates a new extended session, the responsible AN negotiates a common session across the ANs covered by the extended session area. During the session negotiation, each AN establishes a new session and allocates a new Unicast Access Terminal Identifier (UATI). Each AN is notified of each UATI allocated for the extended session. Once the negotiation between ANs is completed, the AT can roam anywhere within the extended session area without re-negotiating the session or transferring session information.

摘要： A Base Station Controller (BSC) in a wireless communication network stores paging location information for a mobile station, and uses that information to determine whether paging the mobile station for mobile-terminated packet data delivery requires mobile switching center (MSC) involvement. For example, the BSC may send a service request message to the MSC to initiate paging of the mobile station by the MSC if the paging location information identifies a service area that is not exclusive to the BSC, and autonomously page the mobile station if the identified service area is exclusive to the BSC. Also, the BSC may autonomously page the mobile station along with sending a service request to the MSC, on the chance that the mobile station actually is within a service area controlled by the BSC. The BSC also may send a service request to the MSC if autonomous paging fails.
摘要翻译：无线通信网络中的基站控制器（BSC）存储针对移动台的寻呼位置信息，并且使用该信息来确定移动终端对移动终端分组数据传送的寻呼是否需要移动交换中心（MSC）参与。例如，BSC可以向MSC发送服务请求消息，以便如果寻呼位置信息识别出不是BSC排他性的服务区域，则由MSC发起移动台的寻呼，并且如果识别出的服务区域是BSC专有的。此外，BSC可以在移动台实际上在由BSC控制的服务区域内的机会的情况下，自主地将移动站寻址，同时向MSC发送业务请求。如果自主寻呼失败，BSC还可以向MSC发送业务请求。

摘要： The invention relates to a method for maintaining a Point-to-Point Protocol (PPP) connection between a Mobile Terminal (MT) and a Packet Data Serving Node (PDSN). Responsive to a detection at the PDSN that the PPP connection between the PDSN and the MT is inactive, the method sends a first Link Control Protocol (LCP) Echo Request, which including a Short Data Burst (SDB) parameter, wherein the SDB parameter indicates that the message is sent using SDB, from the PDSN to a Base Station Controller/Packet Control Function (BSC/PCF) for locating the MT. The method further determines on the reception of SDB parameter, not to setup a traffic channel (TCH) between the MT and a serving BS. Next, the method sends from the BSC/PCF to the BS a second LCP Echo Request, which includes a NO Traffic Channel (No TCH) parameter instructing not to setup a traffic channel for the MT.
