Problems solved by technology

This is difficult in some cases because UE does not always have access to all traffic parameters of outgoing traffic
For example, if different vendors implement different UE components, the entity performing URSP may not be able to determine the traffic parameters of all applications and services that depend on the data connection at the UE
As a result, the UE is not always able to match outgoing traffic to the URSP rule, so the URSP rule may not be applied (if all traffic parameters are known to the UE, the URSP rule would be applicable)

Embodiment Construction

[0021] figure 1 An example communication system 100 is shown in which the routing techniques of the present disclosure may be implemented. The communication system 100 includes a user equipment (UE) 102 , which may be any suitable device capable of wirelessly communicating with a core network (CN) 110 via a base station 104 .

[0022] In general, the UE 102 may determine that a particular traffic descriptor associated with a rule specifying routing of outgoing traffic at the UE 102 is prohibited (or "disabled"), and the UE 102 when matching outgoing traffic to the rule These forbidden descriptors should not be used. Although this disclosure is primarily concerned with URSP rules, these techniques can also be applied to other rule-based routing mechanisms.

[0023] As discussed in more detail below, the UE 102 may determine that a rule includes forbidden traffic descriptors, and then ignore the rule when applying a set of URSP rules. As another example, the UE 102 may determ...

Abstract

Processing hardware in a user equipment (UE) communicating with a core network (CN) via a radio access network (RAN) may implement a method of routing outgoing traffic from the UE. The method includes determining that the UE is to match it to a prohibited traffic descriptor of a CN-defined rule that specifies a route for outgoing traffic (602). The method further includes preventing the rule specifying the routing from being applied to the outgoing traffic using the traffic descriptor (606).

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more particularly, to applying rules at user equipment for routing outgoing traffic. Background technique [0002] This background description is provided for the purpose of generally presenting the context of the present disclosure. To the extent described in this Background section, the work of the presently named inventors and aspects of the description that may have been inconsistent with the prior art at the time of filing are neither expressly nor implicitly admitted to be prior to the present disclosure. technology. [0003] In fifth generation (5G) wireless communication systems, a user equipment (UE) can apply a so-called UE Route Selection Policy (URSP) to outgoing traffic to determine how the UE should behave in the operating system (OS) , specific applications executing on specific domains, specific network hosts, etc. route traffic. As defined by current 5G standar...
