Uplink load generation in communication networks
First Claim
1. A method of generating an uplink (UL) load in a communication network, comprising:
- determining whether a user equipment (UE) in the communication network is in an Idle mode or an Active mode;
if the UE is in the Idle mode;
transmitting a page message to the UE;
determining whether a response to the page message is received;
if the response is received, determining whether UL resources sufficient for UL load generation according to a set of parameters are available;
if sufficient UL resources are available, setting up a radio access bearer to the UE for uplink load generation; and
generating an UL load on the radio access bearer according to the set of parameters; and
if the UE is in the Active mode;
determining whether UL resources sufficient for UL load generation according to the set of parameters are available;
if sufficient UL resources are available, adding a radio access bearer to the UE dedicated to uplink load generation; and
generating an UL load on the radio access bearer added according to the set of parameters.

Abstract
Uplink load generation and control simplify network testing and other tasks. For example, a network operator can decide to test the network by imposing a test load in a selected uplink. The operator can suitably configure an appropriate Mobility Management Entity (MME) with information using a network Operations and Maintenance Support System. In due course, the MME informs the selected user equipment (UE): if the UE is in Idle mode, the network sends a page message; if the UE is in Active mode, with an on-going communication session, the page message is sent after the session ends; and if the UE is detached from the network, the UE is informed during the initial network attach procedure. Thus, uplink load generation is controllable by the network operator, enabling the operator to adjust an existing network and perform realistic simulations on a “green field” network, i.e., a network before launch.

7. A system for generating an uplink (UL) load in a communication network, comprising:
-
a mobility management entity (MME), an evolved NodeB (eNB), and a user equipment (UE); wherein the MME is configured to determine whether the UE is in an Idle mode or an Active mode;
if the UE is in the Idle mode, to cause a page message to be transmitted to the UE, to determine whether a response to the page message is received, and if the response is received, to send a setup request message to the eNB to set up a radio access bearer to the UE for UL load generation; and
if the UE is in the Active mode, to send a modify request message to the eNB to add a radio access bearer to the UE dedicated to UL load generation; andwherein the eNB is configured to determine whether UL resources sufficient for UL load generation according to a set of parameters are available;
if sufficient UL resources are available, to respond to the setup request message by setting up the radio access bearer to the UE for uplink load generation and configuring the UE to generate an UL load on the radio access bearer according to the set of parameters, and to respond to the modify request message by adding the radio access bearer to the UE and configuring the UE to generate an UL load on the radio access bearer added according to the set of parameter. - View Dependent Claims (8, 9, 10)

11. A non-transitory computer-readable medium have non-transient stored instructions that, when executed by a computer in a wireless communication network, cause the computer to carry out a method of generating an uplink (UL) load in the communication network, wherein the method comprises:
-
determining whether a user equipment (UE) in the communication network is in an Idle mode or an Active mode; if the UE is in the Idle mode; transmitting a page message to the UE; determining whether a response to the page message is received; if the response is received, determining whether UL resources sufficient for UL load generation according to a set of parameters are available; if sufficient UL resources are available, setting up a radio access bearer to the UE for uplink load generation; and generating an UL load on the radio access bearer according to the set of parameters; and if the UE is in the Active mode; determining whether UL resources sufficient for UL load generation according to the set of parameters are available; if sufficient UL resources are available, adding a radio access bearer to the UE dedicated to uplink load generation; and generating an UL load on the radio access bearer added according to the set of parameters. - View Dependent Claims (12, 13, 14, 15, 16)
