    Abstract: Upon call set-up requests in a CDMA-based communication system (1), an outer power control loop function is initially armed (158) with a time-averaged Eb/No value for a desired quality of service (QoS) of a specific service-type, e.g. voice, data or video, at a particular location. Clearly, different locations (Xn, Yn) within the communication system (10) are subject to different propagation environments and so the time-averaged Eb/No values (110) vary between services and locations. Generally, as exemplified in Fig 3, an RNC (36-40) is operable to maintain a continuously updated database (100) through recodal of converged outer loop targets (for a cell or georgraphic location) for each specific type of service. When a new call is initiated (150), an initial outer power control loop target is taken (110) to be the time-averaged Eb/No valude from the database (100). In this way, any transient period (160) between call establishment (150-158) and convergence to a true required outer loop threshold is reduced, increasing overall network quality and capacity. The initial default within the database (100) doe not need to be chosed with particular care since it will soon be updated once an associated Node B (26-31) goes live, tereby avoiding the necessity of having to extensively system test new Node B sites in an interference-critical radio environment. The process of updating location-specific converged Eb/No values may be maintained (168) in-call.

    Abstract translation: 在基于CDMA的通信系统（1）中的呼叫建立请求中，外部功率控制回路功能被初始化（158），具有用于期望的服务质量（QoS）的时间平均的Eb / No值 服务类型，例如 语音，数据或视频。 显然，通信系统（10）内的不同位置（Xn，Yn）经受不同的传播环境，因此时间平均Eb / No值（110）在服务和位置之间变化。 通常，如图3所示，RNC（36-40）可操作以通过对于每种特定类型的服务的汇聚外环目标（对于小区或地理位置）进行重新编排来维持连续更新的数据库（100）。 当开始新的呼叫（150）时，采取初始外部功率控制环路目标（110）为来自数据库（100）的时间平均Eb / No值。 以这种方式，减少呼叫建立（150-158）和收敛到真实所需外部环路阈值之间的任何瞬态时段（160），从而提高整体网络质量和容量。 数据库（100）中的初始默认值不需要特别小心选择，因为一旦相关联的节点B（26-31）生效，它将很快被更新，因为避免了必须广泛地系统测试新的节点B 干扰关键的无线电环境中的站点。 可以维护更新位置特定的收敛Eb / No值的过程（168）呼叫。

    Abstract: A communication system (10, 68) includes a plurality of different, spectrally separated air-interfaces providing different services from co-located base sites (70-76). One of these air-interfaces, which may be CDMA, operates a universal frequency-re-use pattern across multiple cells (80, 88, 90), whereas other air-interfaces, such as GSM, have carrier frequencies that have a cell re-use pattern. A subscriber unit (12-16) within the system (10, 68) monitors an interference environment and path loss of at least some of the various different services to infer propagation conditions that are likely to be experienced within a spread spectrum service supported by the universal frequency re-use pattern. Armed with an assessment of a fade (82-86) condition within the system as a whole, implied by time and path loss from broadcast signals from different services, the subscriber unit can regulate and control its power transmission. Spread spectrum communication to a distant base station can be safe in the knowledge that high power transmissions from the subscriber are subject to deep fade when viewed by near-in base sites. Near-far problems associated with high power transmissions to near-in base sites can therefore be mitigated based on a level of confidence that is found in the fade condition determined by path loss in services ancillary to the spread spectrum service.

    Abstract: Upon call set-up requests in a CDMA-based communication system, an outer power control loop function is initially armed (158) with a time-averaged E b /N 0 value for a desired quality of service of a specific service-type, e.g. voice, data or video, at a particular location. Clearly, different locations (x n , y n ) within the communication system are subject to different propagation environments and so the time-averaged E b /N 0 values Fig. 2 (110) vary between services and locations. Generally, an RNC is operable to maintain a continuously updated database through recordal of converged outer loop targets (for a cell or geographic location) for each specific type of service. When a new call is initiated (150), an initial outer power control loop target may be taken to be the time-averaged E b /N 0 value from the database. In this way, any transient period (160) between call establishment (150-158) and convergence to a true required outer loop threshold is reduced, increasing overall network quality and capacity. The initial default within the database does not need to be chosen with particular care since it will soon be updated once an associated Node B goes live, thereby avoiding the necessity of having to extensively system test new Node B sites in an interference-critical radio environment. The process of updating location-specific converged E b /N 0 values may be maintained (168) in-call.
