摘要： A mobile telephone system providing general packet radio service (GPRS) includes a radio network controller (RNC) (2A) and/or a base station controller (BSC) and an associated serving GPRS support node (10A) for each domain. The RNCs (2A) and the SGSNs (10A) are interconnected by an Internet protocol (IP) network. When a mobile telephone (6A) moves from one domain to another, the RNC, in the new domain, takes over handling the mobile telephone. The current SGSN (10A) has a detector (20) which detects whether the existing transmission is a real-time transmission and, if it is, a diverter (22) comes into operation to couple the RNC in the new domain to the current SGSN (10A) rather than its associated SGSN (10A). When the call ends, the current SGSN (10A) hands-over the call to the SGSN (10A) in the new domain. This procedure ensures minimal interruption to real-time services by keeping the call anchored to the current SGSN (10A).
摘要翻译：提供通用分组无线电业务（GPRS）的移动电话系统包括用于每个域的无线电网络控制器（RNC）（A A）和/或基站控制器（BSC）和相关联的服务GPRS支持节点（10A）。 RNC（2A）和SGSN（10A）通过因特网协议（IP）网络互连。当移动电话（6A）从一个域移动到另一个域时，新域中的RNC接管移动电话。当前SGSN（10A）具有检测器（20），其检测现有传输是否是实时传输，并且如果是，则转向器（22）进入操作以将新域中的RNC耦合到当前 SGSN（10A）而不是其相关联的SGSN（10A）。当呼叫结束时，当前SGSN（10A）将新呼叫转移到新的域中的SGSN（10A）。该过程通过将呼叫保持到当前SGSN（10A）来确保对实时业务的最小中断。

摘要： A real time data transmission method is used in a network in which a real time media gateway is provided to allow access to the internet backbone in addition to the usual GPRS specific gateway. The method involves changing the header in a real time data stream as it passes through the network so that it can pass directly to the real time gateway without passing through the GPRS specific gateway. This ensures that the data stream travels along a more direct route and shortens the headers used in the data stream in the process.

摘要： A mobile telephone network provides a network operator domain in which the output from a radio network controller (RAN) is processed by a voice capable serving GPRS support mode (VC-SGSN). The VC-SGSN consists of the combination of a voice service box (VSB) and a service GPRS support node (SGSN). The VSB and the SGSN can jointly access the same home location register). The output of the SGSN can be forwarded to the internet via a gateway GPRS support node while the output of the VSB can be forwarded to the public switched telephone network (PSTN).

摘要： An improved technique reduces unnecessary routing area updates, while ensuring that the location of a mobile terminal is known when the mobile terminal starts data communication after being in a standby state. Routing area updates are controlled in a packet radio access network architecture having a common routing area controlled by a core network and supported by a first wireless access system and a second wireless access system. The first radio access system provides a mode of operation in which a radio link is maintained between a mobile terminal and the first radio access system after completion of a data transmission. A routing area update takes place if the mobile is located in the second radio access system routing area when the next data transmission is initiated. Additionally, if packet transmission is initiated by the core network, the first radio access system receives a paging request and responsive to receipt of the paging request, the first radio access system pages the core network common routing area.

摘要： In the GPRS when a MS moves from a former routing area to a new routing area, a method of supporting mobile Internet protocol characterized in that on receipt of a routing area update message from the MS, a mobile Internet protocol agent advertisement is sent only to that MS. The move may be inter-SGN or intra-SGN or may involve a change of RNC. The method allows efficient use of radio resources.

摘要： An improved technique for reducing unnecessary routing area updates ensures that the location of a mobile terminal is known when the mobile terminal starts data communication after being in a standby state. If no packet transmission is taking place when a mobile terminal moves between the first and second wireless access systems in a common routing area of a packet radio access network, no routing area update takes place. If packet transmission is initiated, no routing area update may be required if the mobile is connected to the same wireless access system as in its previous packet transmission. If packet transmission is initiated, a routing area update may take place if the mobile is connected to a different wireless access system than in the previous packet transmission. If packet transmission is initiated by the mobile, the packet transmission initiation may include the routing area update.
摘要翻译：用于减少不必要的路由区域更新的改进技术确保了当移动终端处于待机状态之后开始数据通信时，移动终端的位置是已知的。如果移动终端在分组无线电接入网络的公共路由区域中的第一和第二无线接入系统之间移动时不发生分组传输，则不进行路由区域更新。如果发起分组传输，则如果移动台连接到与之前的分组传输相同的无线接入系统，则不需要路由区域更新。如果分组传输被启动，则如果移动台连接到与先前的分组传输中的不同的无线接入系统，则可能发生路由区域更新。如果分组传输由移动台发起，则分组传输启动可以包括路由区域更新。
