Abstract: In some implementations, a navigation application can integrate third party services into the navigation application in an easy to use and convenient manner. For example, the navigation application can receive user input indicating that the user is interested reserving a table from a table reservation service. In response to receiving the indication, the navigation application can invoke an application extension for a third party table reservation application. The navigation application and table reservation application can then communicate to provide the table reservation service through the navigation application.

Abstract: A paging procedure of a mobile telecommunications system is modified to page a terminal using all the transceiver node cells in the coverage area allocated to the terminal that operate in the frequency bands indicated by frequency band capability data for the terminal, but not using the transceiver node cells in the coverage area allocated to the terminal that operate only in other ones of the frequency bands. In one embodiment a control entity is operable to initiate an initial paging procedure by paging based on the characteristic of the terminal obtained by the control entity, and to initiate a subsequent paging procedure if no paging response is received from the terminal. In another embodiment, coverage area allocation means allocates each of the transceiver node cells to one or more of the coverage areas in dependence upon on which of the frequency bands the cell is capable of communicating.

Abstract: A protective phone cover dispenser dispenses sleeves that isolate a phone from contaminants in the external environment. The dispenser has a container, a storage compartment, a set of protective covers, an access hole, and an external device coupler. the storage compartment is located within the container and acts as a holding chamber for the set of protective covers. Each of the protective covers is a sleeve that is used to envelop the phone. Thus, isolating the phone from contaminants in the external environment. The access hole traverses through the container into the interior compartment so that a user is able to retrieve the protective covers stored within the interior compartment. The external device coupler is mounted onto the exterior surface of the container and is positioned offset from the access hole. Thus, the dispenser can be mounted onto an external structure without hindering the user from retrieving protective covers.
