Queuing of invocations for mobile web services

Methods and apparatuses for communications between web service applications and web services are described. A first interface is coupled between the application and a messaging system. A second interface is coupled between the messaging system and the web service. The first interface is configured to receive a web service request from the application, to format the web service request into a Simple Object Access Protocol (SOAP) request message, to include the SOAP request message in a first electronic message, and to transmit the first electronic message to the messaging system. The messaging system is configured to receive the first electronic message at a first node, to transmit the first electronic message across a communications network to a second node, and to couple the first electronic message from the second node to the second interface. The second interface is configured to receive the first electronic message from the messaging system, to extract the SOAP request message from the first electronic message, and to transmit the SOAP request message to the web service. Furthermore, a web service response is returned from the web service through the second interface, messaging system, and first interface, to the web service application.
