`
`
`
`
`
`These infringement contentions illustrate Samsung's infringement of the '667 patent by way of the Samsung Galaxy S5 SM-G900x
`(“The Samsung device”) and Samsung’s Core Network Systems http://www.samsung.com/global/business/networks/core-network/
`(“The Samsung System”), as non-limiting examples. This chart shows on an element-by-element basis how The Products literally
`infringe the ‘667 patent. To the extent any particular limitation is not literally met by The Products or the Network Products, it is met
`under the Doctrine of Equivalents. In particular, there would be no substantial difference between the elements of the asserted claims
`and the corresponding functionality in the accused instrumentality, i.e., the corresponding functionality in the accused products does
`substantially the same thing, in substantially the same way to achieve substantially the same results as the claimed elements.

`
`CLAIM 31
`
`Samsung makes, uses, sells, offers to sell, and/or imports The Network Products, each of which is
`capable of providing telecommunications network access to User Equipment (UE)/Terminal to use a
`telecommunications network as set forth in this claim.
`
`Each element of this claim and each element of the asserted claims dependent thereon, is present
`literally or under the doctrine of equivalents in The Network Products, because there is no substantial
`difference between the elements of the asserted claims and the corresponding functionality in the
`accused instrumentality, i.e., the corresponding functionality in the accused products does
`substantially the same thing, in substantially the same way to achieve substantially the same results
`as the claimed elements.
`
`For example, Samsung describes its Mobile Packet Core System, a part of its Core Network
`offerings, on its website as follows:

`
`The Network Products access at least one deny access time interval using a unique identifier to deny
`the access to the terminal with the unique identifier during deny access time period.
`
`For example, the Network Products may deny access to the UE/Terminal during the peak load time
`interval of the telecommunications network and/or when the telecommunications network does not
`have sufficient resources to be accessed by the UE/Terminal. In such case, in response to a
`resource request from the UE/terminal, the Network Products send a REJECT message in response
`to such resource request with a back-off timer value to the UE/Terminal. The back-off timer (T3346
`or T3396) value specifies the duration for which the UE/Terminal is denied access.
`
`When the Network Products deny the access due to congestion, the Network Products store the
`back-off time (T3346 or T3396) for each UE with its unique identifier.

`
`The Network Products are configured to adapt the time period depending on the monitored network
`load.
`
`For example, as described above, the telecommunications network determines the time period of the
`peak load intervals depending on the monitored network load.
`
`For example, the T3396 and T3346 timers are used as back-off timers are adapted based on the
`congestion control and/or the network load. The T3396 and T3346 timers are set to different back-
`off timer values or time periods depending upon the congestion control and/or the network load.

`
`As a further example, when a terminal makes a resource request such as, Location Registration
`Request, PDN Connectivity Request, Bearer Resource Modification Request, PDP Context
`Activation Request, PDP Context Modification Request, or the like, to gain access to the
`telecommunications network resources, the telecommunications network may respond with a
`“Reject” response if the telecommunications network is congested. Such a “Reject” response
`includes a deny access time interval (T3346 or T3396 “back-off timer”), which is a time period during
`which the telecommunication network may deny access.

`
`Samsung makes, uses, sells, offers to sell, and/or imports the Network Products which contain a
`tangible, non-transitory computer-readable medium that stores instructions which when executed by
`one or more processor of the Network Products cause the telecommunications network to perform
`operations described herein.
`
`For example, Samsung Packet Controller and Packet Core Gateway comprise of one or more
`processors that can execute the instructions stored on the computer storage media perform
`operations described below.
`
`Samsung Core Network products connect User Equipment (UE)/Terminal on a telecommunications
`network as set forth in this claim.
`
`Each element of this claim and each element of the asserted claims dependent thereon, is present
`literally or under the doctrine of equivalents in the Network Products, because there is no substantial
`difference between the elements of the asserted claims and the corresponding functionality in the

`
`The Network Products access at least one deny access time interval using a unique identifier to deny
`the access to the terminal during deny access time period.
`
`In response to a resource request, the Network Products deny access to the UE/Terminal during
`peak load time intervals and/or the telecommunications network does not have sufficient resources.
`During such time interval, in response to a resource request, the Network Products send a REJECT
`message with a back-off timer value to the UE/Terminal. The back-off timer value specifies the
`duration for which the UE/Terminal may be denied access.
`
`For example, in response to a resource request, the Network Products may deny an access to the
`UE/terminal by sending a “reject” message when the telecommunication network is congested. This
`“reject” message includes a back-off timer value indicating a time value during which the Network
`Products will deny further resource requests to the telecommunications network by the UE/Terminal
`with the particular unique identifier.
`
`The below excerpt from the 3GPP standard describes rejecting an ATTACH REQUEST with T3346
`timer value:
`
`“5.5.1.2.5 Attach not accepted by the network If the attach request cannot be accepted by the
`network, the MME shall send an ATTACH REJECT message to the UE including an appropriate
`EMM cause value. ... If the attach request is rejected due to NAS level mobility management
`congestion control, the network shall set the EMM cause value to #22 "congestion" and assign a
`back-off timer T3346..” See TS 24.301, Clause 5.5.1.2.5(Attach not accepted by the network).
