A system for managing of mobile phones at a roaming network, each mobile handset having a first handset number from its home network. The roaming network assigns a second number to a detected roamer, which number is local to the roaming network. The second number is not known directly to the handset, which continues to identify itself using the first number. The handling unit acts as a local home location register for handling local management of the roaming handset using both the second number and the first number, thus allowing the handset to identify itself using the first number but be called using the second number at local call rates.

A web-based hosted solution through which business entities create and manage communications campaigns, such as interactive campaigns that afford target recipients an opportunity to be connected to a third party call center. A web interface is provided to enable a business entity customer to create a set of one or more rules that, when triggered during the campaign, cause the hosted solution to take certain control actions in real-time, based on campaign performance. Preferably, this “campaign performance” is measured indirectly, i.e. without requiring a direct connection to an on-premises call center ACD. Rather, preferably all information about the call center's performance during the campaign is derived from information (gathered by the hosted solution) about calls delivered, or attempted to be delivered, to the call center. In effect, the call center performance is inferred, and this performance is then exposed to the business entity customer through a web-based interface. In particular, the interface provides the business entity customer with a convenient and easy-to-use display that identifies any rule that has been (or may be getting ready to be) triggered, together with a then current status of the campaign. The system is programmed to take a given control action (e.g., campaign suspension, adjusting an outbound call rate, or the like) when a customer-configurable rule is triggered.

The invention discloses a method and LTE (long term evolution) system for across node B handover of a user terminal. The method comprises: after receiving a handover request from the user terminal, a target evolved node B (eNB) utilizes a target cell handover information to generate target cell reestablishment information and locally store the target cell reestablishment information; after receiving a reestablishment request from the user terminal, the target eNB judges whether the reason values in the reestablishment request are handover failures or not, if not, the target eNB matches the target cell reestablishment information with the user terminal; and then reestablishment succeeds. Compared with the prior art, the handover method and the LTE system have the following advantages: when the UE sends the reestablishment request to the target eNB and if the reason values in the reestablishment request are not handover failures, the target eNB matches the reestablishment ready information generated by target cell information with a UE (user equipment) entity, and then the reestablishment succeeds. By utilizing the method, the success rate of the establishment during the handover process is improved, thereby ensuring that the UE has no dropped call, and reducing the dropped call rate of the UE.
