Overview of 4G LTE

Cisco EHWIC-4G-LTE Features

SIM Lock Feature

Overview of 4G LTE

Cisco 4G LTE WWAN EHWICs (EHWIC-4G-LTE-V, EHWIC-4G-LTE-A, and EHWIC-4G-LTE-G) support 4G LTE cellular and 3G cellular networks.

The EHWIC-4G-LTE comes with Sierra Wireless multimode modem that supports the following modes:

3G Evolution-Data Optimized (EVDO or DOrA) Mode—EVDO is a 3G telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. DOrA refers to EVDO Rev-A. EVDO uses multiplexing techniques including Code Division Multiple Access (CDMA), as well as Time Division Multiple Access (TDMA), to maximize both individual users' throughput and the overall system throughput.

3G Evolution High-Speed Packet Access (HSPA/HSPA+)—HSPA is a UMTS-based 3G network. It supports High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA) data for improved download and upload speeds. Evolution High-Speed Packet Access (HSPA+) supports Multiple Input/Multiple Output (MIMO) antenna capability.

4G LTE—4G LTE mobile specification provides multi-megabit bandwidth, more efficient radio network, latency reduction, and improved mobility. LTE solutions target new cellular networks. These networks initially support up to 100 Mb/s peak rates in the downlink and up to 50 Mb/s peak rates in the uplink. The throughput of these networks is higher than the existing 3G networks.

Figure 1 shows a 4G LTE packet core network and the network elements it contains.

Figure 1 4G LTE Packet Core Network Architecture

Gateways

The Serving Gateway (SGW) routes and forwards user data packets, while also acting as the mobility anchor for the user plane, and is the anchor for mobility between LTE and other 3GPP technologies. The Packet Data Network (PDN) Gateway (PGW) provides connectivity from the User Equipment (UE) to external packet data networks by being the point of exit and entry of traffic for the UE.

A UE may have simultaneous connectivity with more than one PGW for accessing multiple PDNs. The PGW performs policy enforcement, packet filtering for each user, charging support, lawful interception, and packet screening. Another key role of the PGW is to act as the anchor for mobility between 3GPP and non-3GPP technologies such as WiMAX and 3GPP2 (CDMA 1X and EvDO).

The System Architecture Evolution GW (SAE GW) is the entity that covers the PGW and SGW functionality in the Evolved Packet Core (EPC).

RNC

The Radio Network Controller (RNC) is responsible for controlling the Radio Access Network (RAN) that are connected to it. The RNC carries out radio resource management and some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile. The RNC connects to the Circuit-Switched Core Network through the Media Gateway (MGW).

BTS

Base Transceiver Station.

BSC

Base Station Controller.

SGSN

Service GPRS Support Node.

Mini USB type 2 connector for modem provisioning

Single UICC (USIM)

SIM Lock Feature

Cisco 4G LTE EHWICs need an active Subscriber Identity Module (SIM) provided by your service provider. The SIM cards are generally given out as unlocked (can be used without a PIN) versus locked (requires PIN configuration). Cisco IOS has a SIM Lock feature that allows you to lock and unlock a SIM and to set or change the PIN code. This feature ensures that the SIM is only used in an authorized device (in this case, a Cisco ISR G2). The SIM lock and unlock procedures are carried out using Cisco IOS CLI via console or Telnet/SSH to the ISR.

For instructions on SIM configuration, see the "How to Configure Cisco 4G LTE Wireless WAN EHWICs" section.

How to Configure Cisco 4G LTE Wireless WAN EHWICs


Note For 4G-LTE EHWICs, the numbering for slot 0, wic 0, and port 0 is 0/0/0 for all commands. Please refer to platform-specific documentation for details on slot numbering.



Note For Cisco 819 4G LTE fixed platforms, use slot "0" for all commands.


To configure the 4G-LTE features, follow these procedures:

protocol

Network protocol: IPv4.


SIM Configuration

The SIM can be in two states—locked or unlocked. If the SIM is unlocked, it can be inserted into an EHWIC and used without an authorization code.

The SIM can be initially locked with a four- to eight-digit PIN code defined by the ISR administrator. The SIM Lock feature can be used to lock the SIM using the PIN code. Once it is locked, it cannot initiate a call unless authentication is done using the same PIN. Authentication is done automatically by Cisco IOS via configuration of the PIN. This required configuration for automatic SIM authentication is done using Cisco IOS CLI as part of the router start-up configuration.

Once the Cisco IOS configuration is in place, the ISR can initiate an LTE connection. The ISR uses the configured PIN to authenticate prior to LTE connection. If the Cisco IOS PIN configuration is missing or if the PIN is wrong, the SIM authentication will fail and the connection will not be initiated.

If the locked SIM is moved to a different ISR or to another device, or if the EHWIC in which the locked SIM resides is moved to a different EHWIC slot in the same ISR, the ISR configuration needs to be changed. The configuration is associated with the cellular controller that is specific to an ISR EHWIC slot number. This will ensure that the SIM card will not be used in any unauthorized device or, if there are multiple LTE EHWICs in a single ISR, that the appropriate PIN is applied to each LTE EHWIC/SIM. An authentication command (with the same PIN used to lock the SIM) must be defined on the new device or on the new cellular controller slot to successfully initiate the LTE connection.

To configure the SIM, follow these procedures:

Locking and Unlocking the SIM Card Using a PIN Code

Automatic SIM Authentication To Set Up Data Call With a Locked SIM


Caution It is very important to use the correct PIN once it is configured. The SIM card will get blocked if the wrong PIN is entered three consecutive times on a locked SIM during authentication or when trying to unlock a locked SIM.

Blocked SIM cards cannot be unblocked. For Cisco 4G LTE EHWICs, contact your service provider to replace your SIM card if it gets blocked due to wrong PIN attempts during locking/unlocking or authentication.

Locking and Unlocking the SIM Card Using a PIN Code

To lock or unlock the SIM card provided by your service provider, enter the following commands in privileged EXEC mode.


Caution The SIM card will get blocked if the wrong PIN is entered three consecutive times. Make sure you enter the correct PIN that the SIM is configured with. If your SIM card gets blocked, contact your service provider for a SIM card replacement.

SUMMARY STEPS

Step 3 

show cellular slot/wic/port security

Example:

Router# show cellular 0/0/0 security

(Optional) Shows the security information for the modem, including SIM lock status.

Automatic SIM Authentication To Set Up Data Call With a Locked SIM

To allow automatic SIM authentication everytime the modem is getting ready to place a call, you need to configure the SIM Card Holder Verification (CHV1) code for the locked SIM card using the correct PIN code.

To configure the SIM CHV1 code for verification, enter the following commands starting in EXEC mode.


Caution The SIM card will get blocked if the wrong PIN is entered three consecutive times. Make sure you enter the correct PIN that the SIM is configured with. If your SIM card gets blocked, contact your service provider for a SIM card replacement.


Note Follow these procedures when using an unencrypted level 0 PIN to configure CHV1. For instructions on how to configure CHV1 using an encrypted level 7 PIN, see the "Configuring an Encrypted PIN" section.



Note The SIM needs to be locked for SIM authentication to work. To verify the SIM status, use the show cellular slot/wic/port security command.


SUMMARY STEPS

1. configure terminal

2. controller cellular slot/wic

3. lte sim authenticate 0 pin

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 2 

controller cellular slot/wic

Example:

Router(config)# controller cellular 0/0

Enters the cellular controller configuration mode.

Step 3 

lte sim authenticate 0 pin

Example:

Router(config-controller)# lte sim authenticate 0 1111

Configures CHV1 using the PIN code. This PIN is sent to the modem for authentication with each subsequent LTE connection. If authentication passes based on the configured PIN, the data call will be allowed. If authentication fails, the modem will not initiate the data call.

This command is valid only when an unencrypted (clear text) level 0 PIN is used to configure CHV1. To set a level 7 PIN, a valid encrypted string representing a PIN of four to eight digits must be used. To configure CHV1 using an encrypted PIN, see the "Configuring an Encrypted PIN" section.

Configuring an Encrypted PIN

To configure an encrypted PIN, the scrambled value for the PIN must be obtained. To get the scrambled level 7 PIN and to configure the SIM CHV1 code for verification using this encrypted PIN, enter the following commands starting in EXEC mode.


Note The method shown here is one way of obtaining the encrypted PIN. In this method, a username and password is created by configuring password encryption, defining the username and associated password, copying the resulting scrambled password, and using this scrambled password in the SIM authentication command. After the scrambled PIN has been obtained and used in SIM authentication, the username created may be deleted from the Cisco IOS configuration.



Note The SIM needs to be locked for SIM authentication to work. To verify the SIM status, use the show cellular slot/wic/port security command.

Step 5 

controller cellular slot/wic

Example:

Router(config)# controller cellular 0/0

Enters the cellular controller configuration mode.

Step 6 

lte sim authenticate 7 pin

Example:

Router(config-controller)# lte sim authenticate 7 055A575E70

Configures CHV1 using the scrambled PIN from Step 4. This PIN is sent to the modem for authentication with each subsequent LTE connection. If authentication passes based on the configured PIN, the data call will be allowed. If authentication fails, the modem will not initiate the data call.

This command is valid only when an encrypted (hidden) level 7 password is used to configure CHV1.

Step 7 

exit

Example:

Router(config-controller)# exit

(Optional) Exits the cellular controller configuration mode.

Step 8 

no username name

Configuring DDR Backup

To monitor the primary connection and initiate the backup connection when needed, the router can use one of the following methods:

Backup Interface—The backup interface that stays in standby mode until the primary interface line protocol is detected as down and then is brought up.

Floating Static Route—The route through the backup interface has an administrative distance that is greater than the administrative distance of the primary connection route and therefore would not be in the routing table until the primary interface goes down.

Dialer Watch—Dialer watch is a backup feature that integrates dial backup with routing capabilities.

Modem Firmware Upgrade

The Cisco 4G-LTE EHWICs and Cisco WWAN 4G ISRs G2 have a 4G-LTE modem from Sierra Wireless. The firmware for the modem is upgradable using Cisco IOS commands. The firmware is a Crossword Express file (cwe) and can be downloaded from the wireless software download page on Cisco.com. Use the following procedure to upgrade the modem firmware:


Caution Use only Cisco certified firmware. Using a firmware version not certified by Cisco may impact the wireless service provider network adversely.


Caution Do not disconnect power or switch the router off during the firmware upgrade process. This may result in permanent modem failure.


Note Firmware downgrade is not supported.



Note You can also remotely download firmware over the air by following the same steps listed below.


The latest certified firmware version for your carrier and Cisco IOS compatibility is available at:

http://www.cisco.com/go/4g

SUMMARY STEPS


Step 1 Go to the Cisco Wireless WAN software download website at:

http://www.cisco.com/go/4g


Note For remote download, you can transfer this using the 4G wireless link from Cisco.com onto flash. You must configure external dialer and dialer persistent to bring the interface and the dialer up again.


Step 2 Download the appropriate LTE firmware from the link in Step 1.

Step 3 Use the following command to initiate the firmware upgrade process:

microcode reload cellular pa-bay slot modem-provision flash:filename


Note For remote downloads, if wireless is your primary link, you will lose connectivity. Connectivity is restored after the download. If you have opted for logging in Step 3, the firmware log file will be available on flash with the download status.



DETAILED STEPS

 
Command or Action
Purpose

Step 1 

Go to the Cisco Wireless WAN software download website at:

http://www.cisco.com/go/4g

SNMP MIBs

This section provides a brief description of SNMP MIBs and contains the following topics:

Overview

EHWIC-4G-LTE MIBs

Restrictions

Overview

Simple Management Network Protocol (SNMP) development and its use is centered around the MIB. An SNMP MIB is an abstract data base, which is a conceptual specification for information that a management application may read and modify in a certain form. This does not imply that the information is kept in the managed system in that same form. The SNMP agent translates between the internal data structures and formats of the managed system and the external data structures and formats defined for the MIB.

The SNMP MIB is conceptually a tree structure with conceptual tables. Cisco 4G MIB is discussed in more detail in the next section. Relative to this tree structure, the term MIB is used in two senses. In one sense, it is actually an MIB branch, usually containing information for a single aspect of technology, such as a transmission medium or a routing protocol. An MIB used in this sense is more accurately called an MIB module and is usually defined in a single document. In the other sense, an MIB is a collection of such branches. Such a collection might comprise, for example, all the MIB modules implemented by a given agent or the entire collection of MIB modules defined for SNMP.

An MIB is a tree where the leaves are individual items of data called objects. An object may be, for example, a counter or a protocol status. MIB objects are also sometimes called variables.

MIBs can be classified into three categories:

IF MIBs—describes interface statistics

ENTITY-MIBs—provides general hardware type for both the HWIC and the modem

3G/Wireless MIBs—cellular or wireless-specific MIBs

EHWIC-4G-LTE MIBs

The following MIBs are supported on the EHWIC-4G-LTE-V, EHWIC-4G-LTE-A, and EHWIC-4G-LTE-G:

IF-MIB

ENTITY-MIB

CISCO-WAN-3G-MIB

You can download the MIBs from the Cisco MIB Locator at http://www.cisco.com/go/mibs.

Restrictions

For the router that runs the SNMP agent, you must configure appropriate access control (for example, SNMP-server community) using the Cisco IOS CLI for the NMS and agent to work properly.

It is strongly recommended that you configure SNMP V3 with authentication/privacy when implementing SNMP SET operation.

Troubleshooting

This section provides the necessary background information and resources available for troubleshooting the Cisco 4G-LTE Wireless WAN EHWIC.

For LED descriptions, see Cisco 4G LTE Wireless WAN EHWIC.

Verifying Data Call Setup

Checking Signal Strength

Verifying Service Availability

Successful Call Setup

Modem Troubleshooting Using the Remote Diagnostic Port

Modem Settings for North America and Carriers Operating on 700 MHz Band

Verifying Data Call Setup

To verify the data call setup, follow these steps:


Step 1 After you create a modem data profile using the cellular profile create command and configuring DDR on the cellular interface, send a ping from the router to a host across the wireless network.

Step 2 If the ping fails, debug the failure by using the following debug and show commands:

debug chat

debug modem

debug dialer

show cellular all

show interface cellular

show running-config

show ip route

Step 3 Save the output from these commands and contact your system administrator.


Checking Signal Strength

If the Received Signal Strength Indication (RSSI) level is very low (for example, if it is less than
-110 dBm), follow these steps:


Step 1 Check the antenna connection. Make sure the TNC connector is correctly threaded and tightened.

Step 2 If you are using a remote antenna, move the antenna cradle and check if the RSSI has improved.

Step 3 Contact your wireless service provider to verify if there is service availability in your area.


Verifying Service Availability

The following is a sample output for the show cellular all command for a scenario where the antenna is disconnected and a modem data profile has not been created. The errors in this case have been highlighted with >>>>>>>.

Modem Troubleshooting Using the Remote Diagnostic Port

The RSVD port on the faceplate of the EHWIC-4G-LTE provides access to the debug port on the modem. Use an industry-standard diagnostic tool like Qualcomm QXDM to perform remote radio-level diagnostics and traffic monitoring on the modem.

Use the following test command to turn diagnostics on:

test cell-hwic slot/port/ehwic dm-port remote on


Note To enable test commands, you must enter the service internal command in the global configuration mode.


Modem Settings for North America and Carriers Operating on 700 MHz Band

For HWIC-3G deployments in North America and for carriers operating in the 700 MHz band, the following changes to the modem settings are required to prevent long network attach times.

The output of show cellular x/x/x all command shows the following:

Current RSSI is -125 dBM

LTE Technology Preference = No preference specified (AUTO)

Changing Modem Settings

To change the modem settings to force the modem to scan different technologies, use the following Cisco IOS command:

Router# cellular 0/0/0 lte technology ?
auto         Automatic LTE Technology Selection
cdma-1xrtt   CDMA 1xRTT
cdma-evdo    CDMA EVDO Rev A
cdma-hybrid  HYBRID CDMA
gsm          GSM
lte          LTE
umts         UMTS

Electronic Serial Number (ESN)

The ESN number is located directly on the modem label in hexadecimal notation. It can also be retrieved using the Cisco IOS CLI using the show cellular slot/port/hwic hardware command.

The sample output below shows the ESN number:
