IPNE Service

With Release 18, the MME supports IP Network Enabler (IPNE).


Important

This feature, with its CLI commands, counters, and statistics, are all under development for future use and the information listed here is recommended for testing and lab use only. When the feature is ready for deployment then additional information will be added to this chapter.

Feature Description

IP Network Enabler (IPNE) is a Mobile and IP Network Enabler (MINE) client component that collects and distributes session and network information to MINE servers. The MINE cloud service provides a central portal for wireless operators and partners to share and exchange session and network information to realize intelligent services.

The information is shared between the MINE server and IPNE service in the form of XML data. The core object in the IPNE service is the XMPP protocol engine. There is one XMPP protocol engine instance for each configured MINE server peer. The engine implements the XMPP protocol using FSM.

All information that is shared is derived from the context at that instance in time. An IPNE service level scheduler is also implemented to rate-control the feed and notification activities on all the handles to avoid overload which would affect call processing and data path performance.

With support of the IPNE interface and IPNE Service, the MME is able to export the following information to the CSB (Cisco Service Bus):
  • UE Location Information
  • UE Mobility Information

The ability to export to the CSB makes it possible for operators to design and/or implement solutions and services for network optimization, congestion, troubleshooting and monetization with the information exported from the MME.

IPNE is a licensed Cisco feature. Contact your Cisco account representative for information on licensing requirements. For information on installing and verifying licenses, refer to the Managing License Keys section in the System Administration Guide.

How It Works

IPNE

When the MME service is associated with an IPNE service, then the MME service communicates with the IPNE service through the Session Manager over a SINE interface. The IPNE service communicates with CSB over XMPP protocol.

Information is exchanged between the modules in the form of clp handles. For each session one IPNE handle is created.

Configuring MME Use of IPNE

There are multiple components that need to be configured to enable the MME to utilize the IPNE service:
  • IPNE service
  • IPNE endpoint
  • association with MME service

Configuring IPNE Service

The IPNE service is a separate service configuration.


Important

We recommend that you configure the IPNE service in the same context in which the MME service has been configured. 

config  
   context  context_name 
      ipne-service  ipne_svce_name  
      end

Notes:

  • ipne_service - Enter 1 to 63 alphanumeric characters to create a unique IPNE service name within the context and to enter the IPNE Service configuration mode. Entering the mode provides access to the commands, such as ipne-endpoint , needed to configure the IPNE service parameters.
  • no - As a prefix of the command disables the feature when it has been enabled with this command and removes the IPNE service definition from the MME's configuration. If an IPNE service is to be removed and the service has actives handles, then the handles are deleted using a timer-based approach and then the IPNE service is removed.

Configuring the IPNE Endpoint

After the IPNE service is created, the IPNE endpoint definition should be added to the configuration. An IPNE endpoint is a combination of a local IP address, a peer address and, optionally, a port. Entering the ipne-endpoint command also provides access to the commands in the IPNE Endpoint configuration mode that are used to define the operational parameters required by the endpoint. 

config  
   context  context_name 
      ipne-service  ipne_svce_name 
         ipne-endpoint  
            bind { ipv4-address | ipv6 address }  ip_address 
            peer { ipv4-address | ipv6 address }  ip_address 
            end  
            no { bind | peer }

Notes:

  • { ipv4-address | ipv6-address } ip_address : Identify the type of IP address - either IPv4 or IPv6 - and then enter either an IPv4 dotted-decimal or an IPv6 colon-separated hexadecimal notation.
  • As part of the bind command, the IP address identifies the IPNE client socket as the local address.
  • As part of the peer command, the IP address identifies the MINE server as the peer address.
  • no - Include as a prefix of either the bind or peer command to remove the bind address or the peer address from the IPNE endpoint configuration.

Configuring the Association with MME Service

A special ipne-service keyword has been added to the associate CLI to associate the created IPNE service with the MME service: 
configure  
   context  context_name 
      mme-service  mme_srvc_name 
         associate ipne-service  ipne_srvc_name 
         no associate ipne-service  
         end

Notes:

  • ipne_srvc_name - Enter 1 to 63 alphanumeric characters to identify the unique IPNE service name that is within the same context as the MME service configuration.
  • no - Include as a prefix of the command to disassociate the IPNE service definition from the MMEs service configuration.

Monitoring and Troubleshooting the IPNE Service

Show Command(s) and/or Outputs

This section provides information regarding show commands and/or their outputs in support of using the IPNE service on the MME.

show ipne peers { all | service | summary }

This command generates a display of information for the IPNE service(s) and the TCP connection status for associated Session Manager(s). The following are sample displays: 

show ipne peers all 
SESSMGR :  1 
Service Name: ipne-service         Contex id: 3 
Version : n/a 
Local Address  : 192.168.120.1:45161 
Peer Address : 192.168.120.7:5222    State : [OPEN 0/1] [TCP] 
show ipne peers summary 
Service Name: ipne-service Contex id: 3 
Version : n/a 
Local Address : 192.168.120.1:45161 
Peer Address : 192.168.120.7:5222 State : [OPEN 144/144] [TCP]

Notes:

  • all - Lists all of the peers of each IPNE service and the state of the TCP connections for every SessMgr. This command with all option is part of the support details (SSD) procedure.
  • service - Requires the inclusion of an IPNE service name and displays information only for that service.
  • summary - Generates a display similar to the all display but provides only summary TCP connection information for the SessMgrs.

show ipne statistics { all | service | summary }

This command generates a display of information regarding the number of IPNE handles of each IPNE service and count information for query/response/subscription/feed messages for the SessMgrs. The command generates a display similar to the following: 

show ipne statistics all 
SESSMGR :  1 
Service Name: ipne-service         Context id: 3 
Total handles: 0 
Local Address  : 192.168.120.1:0
