Problems solved by technology

Typically, mobile devices cannot predict which PDP contexts will be deactivated
This can lead to poor user experience, especially if the PDP context used for voice calls is deactivated

Embodiment Construction

[0020] wireless communication system

[0021] now refer to Figure 1A , FIG. 1 shows a block diagram of an example wireless network 100 and mobile device 10 . The wireless network 100 has a first routing area 30 and a second routing area 40 . There may be other routing areas as well, but are not shown for clarity. Each routing area has at least one RNC (Radio Network Controller). In the illustrated embodiment, the first routing area 30 has a first RNC 31 and a second RNC 32 , and the second routing area has a single RNC 41 . Each RNC 31, 32, 41 is associated with the corresponding RNC Id. The first RNC 31 and the second RNC 32 of the first routing area 30 have an RNC Id 31a and an RNC Id 32a respectively, while the single RNC 41 of the second routing area 40 has an RNC Id 41a. Each cell (not shown) within the RNC is associated (via Node B) with a RAI (Routing Area Identity) in a hierarchical manner. RAI can include one or more cells and span RNCs. In some embodiments, ...

Abstract

Systems and Methods are provided for deactivating IP sessions of lower priority. There may be instances when a mobile device moves from a first area supporting a plurality of IP sessions to a second area supporting fewer IP sessions. In this situation, if the mobile device has more IP sessions than is supported by the second area, then the wireless network will deactivate IP sessions. According to an embodiment of the application, the mobile device determines a respective priority for each of the IP sessions and transmits an indication of each respective priority to the wireless network. According to another embodiment of the application, the wireless network deactivates IP sessions that are indicated to be of lower priority. Accordingly, IP sessions that are not deactivated are those indicated by the mobile device to be of greater priority.

Description

technical field [0001] This application relates to wireless communications, and in particular to IP sessions. Background technique [0002] The communication between the mobile device and the corresponding node takes place over a UMTS (Universal Mobile Telecommunications System) network via a GPRS (General Packet Radio Service) serving node. GPRS service nodes include SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node). Such communication exchanges between the mobile device and the corresponding nodes include communication exchanges between the mobile device and the SGSN. Communication exchanges between mobile devices and SGSN nodes, such as user plane communications (ie IP data traffic), use one or more PDP contexts. Multiple PDP contexts may exist based on the number of different applications that the mobile device communicates through the PDP context. However, the PDP contexts for a mobile device may be limited by the number of PDP contexts supported ...
