Embodiment Construction

[0015] The systems and methods of the present patent application are now described with reference to various examples of how best to make and use the embodiments. Like reference numerals are used throughout and in the views of the several drawings to indicate like or corresponding parts, wherein various components are not necessarily drawn to scale. Referring now to the attached drawings, especially figure 1 , shows a typical network environment 100 including a wireless packet data service network 112 implementing an embodiment of the present patent application. Enterprise network 12, which may be a packet-switched network, includes one or more geographic locations and is organized as a local area network (LAN), wide area network (WAN), or metropolitan area network (MAN), etc., to serve multiple corporate users. A plurality of application servers 104-1 through 104-N provided as part of the enterprise network 102 are operable to provide or implement, for example, email, video ...

Abstract

In one embodiment, a scheme is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network (112). Upon detecting that a causecode (404) has been returned by a node (206, 208) disposed in a wireless packet data service network (112), a structure (400) is interrogated to determine if the cause code (404) is mapped to a flag (406) relating to the device's data session retry mechanism. Responsive to determining that the received cause code (404) is mapped as a critical cause code, the data session retry mechanism of the mobile communications device (116) is disabled so that further signaling messages towards the network are prevented.

Description

technical field [0001] This patent application relates generally to wireless packet data service networks. More specifically, and not as a limitation, the present application relates to a solution for customizing a data session retry mechanism of a wireless device in a wireless packet data service network. Background technique [0002] Radio resources in a wireless packet data service network are scarce. When a data center mobile device continues to negotiate with the network infrastructure to establish a data session even after it has received a certain rejection code, such repeated attempts can lead to increased signaling load in the network, negatively affecting the overall performance of the network . Contents of the invention [0003] In one embodiment, a scheme for customizing a wireless device data session retry mechanism in a wireless packet data service network is provided. Upon detection of a cause code being returned by a node located in a wireless packet dat...
