20080220800 | DATA-CAPABLE NETWORK PRIORITIZATION WITH REDUCED DELAYS IN DATA SERVICE - In one illustrative method, a periodic location update timer value is broadcasted by a wireless communication network and received and stored in memory of a mobile station. A request for data service is transmitted by the mobile station to a wireless communication network, and the request is reattempted at least one time in response to identifying a rejection of the request. If the request for the data service is accepted in response to the request, the mobile station operates in the wireless communication network using the data service. On the other hand, if the request for the data service is not accepted, the mobile station is set in a data service deregistered state. A timer is initialized with an initial value that is less than the periodic location update timer value and started. In response to an expiration of the timer, the mobile station repeats the transmission of the request for the data service and any reattempts in response to any rejections of the request. If the periodic location update timer value is less than the initial value, however, the timer is initialized with the periodic location update timer value. | 09-11-2008 |
20100048208 | DATA-CAPABLE NETWORK PRIORITIZATION WITH REJECT CODE HANDLING - Reject code handling is utilized for a more time-efficient selection of data-capable networks. One illustrative method for use in selecting a wireless communication network for communications involves the steps of causing a request for data connectivity to be transmitted through a first wireless network; reattempting the request for data connectivity through the first wireless network one or more times if a reject code comprising a non-critical error is received in response to the request for data connectivity through the first wireless network; and attempting to select a second wireless network for communications without reattempting the request for data connectivity through the first wireless network one or more times if a reject code comprising a critical error is received in response to the request for data connectivity through the first wireless network. | 02-25-2010 |
20100203888 | Data-Capable Network Prioritization With Reject Code Handling - Reject code handling is utilized for a more time-efficient selection of data-capable networks. One illustrative method for use in selecting a wireless communication network for communications involves the steps of selecting a first wireless network available for communications with the mobile station; causing a request for data connectivity to be transmitted to the first wireless network selected; if a rejection is received from the first wireless network in response to the request for data connectivity: reattempting the request for data connectivity to the first wireless network at least one time; selecting a second wireless network available for communications with the mobile station after the request for data connectivity to the first wireless network is reattempted the at least one time without success; and selecting the second wireless network available for communications with the mobile station without reattempting the request for data connectivity to the first wireless network the at least one time if a reject code associated with the rejection indicates that data services are not allowed in the first network is received from the first wireless network in response to the request for data connectivity. | 08-12-2010 |
20110021190 | Network Selection Methods And Apparatus With Home Network Prioritization After Network Signal Recovery Or Power-On - A network selection method for a mobile station which is associated with a Home Public Land Mobile Network (HPLMN) identified by a home Mobile Network Code (MNC) and Mobile Country Code (MCC) pair. The mobile station identifies a plurality of PLMNs in a geographic area, and selects a non-home PLMN identified by a non-home MNC/MCC pair and designated as a Registered PLMN (RPLMN). In response to regaining signal coverage from an out-of-coverage condition with the RPLMN, or being powered-on from a power-off state entered while operating with the RPLMN, the mobile station selects the HPLMN if the HPLMN identified by the home MNC/MCC pair is available. Otherwise, if the HPLMN is unavailable and the RPLMN identified by the non-home MNC/MCC pair is available, the mobile station selects the RPLMN. However, if the RPLMN is unavailable, the mobile station selects an alternate PLMN in accordance with an automatic or manual network selection method. | 01-27-2011 |
20110134815 | DATA-CAPABLE NETWORK PRIORITIZATION WITH REDUCED DELAYS IN DATA SERVICE - In one illustrative method, a method in a mobile station for use in reducing delays for data communications is described. The mobile station causes a request for packet data service to be sent to a wireless communication network. If the request for the packet data service is denied in response to the request, then the mobile station is set in a deregistered state. In addition, the mobile station initializes a timer with an initial value that is less than a periodic location update timer value which is broadcasted by the wireless communication network, and runs the timer. In response to an expiration of the timer, the mobile station causes another request for the packet data service to be sent to the wireless communication network. | 06-09-2011 |
20120115478 | Data-Capable Network Prioritization With Reduced Delays In Data Service - A mobile device sends to a wireless network a request for establishing a service. In response to a rejection of the request, the device reattempts the request so long as the total number of requests is less than a predetermined value. When the total number of rejected requests is greater than or equal to the predetermined value, the device selects a different wireless network with which to establish the communication service if the wireless network is a non-home network. Otherwise, if the wireless network is the home network, the mobile device runs a timer which is initialized with an internal timer value instead of a network timer value when the internal timer value is less than the network timer value. In response to an expiration of the timer, the mobile device sends to the wireless network another one or more requests for establishing the service. | 05-10-2012 |
20140086050 | DATA SERVICE LEVEL UPLINK DATA FLOW CONTROL - A method and a mobile device for limiting uplink transmission for user data at the data service level are provided. At least one least one characteristic related to uplink transmission is monitored and uplink transmission for user data is limited at the data service level based at least in part on the at least one characteristic. Battery power can potentially be saved by limiting uplink transmission for user data at the data service level when uplink transmission is unlikely to be successful. | 03-27-2014 |
20140112223 | SYSTEM AND METHOD FOR REDUCING POWER CONSUMPTION BASED ON DATA ACTIVITY SENSITIVE TIMERS - Where a source of data has a time at which it is to transmit data, if it has data to transmit, for example as determined by a timer, this time is advanced when there is an active data connection. In this manner, rather than the data connection being torn down, and then immediately set up again, the data can be transmitted before the connection is torn down. In some embodiments, a history is maintained in terms of how long data connections are maintained. Then, once data transmission on an active connection ceases, the times are advanced, or not, depending on a likelihood that the connection will stay up for some further period of time. | 04-24-2014 |
