The MME MSC Pool Area Configuration Mode is used to create and manage the MSC Pool Areas used by the MME for communicating with the Mobile Switching Center (MSC) for Single Radio Voice Call Continuity (SRVCC).

Configures the selection of MSC in a MSC pool area based on the hash value derived from the IMSI.
MME
Administrator
Exec > Global Configuration > Context Configuration > MME Service Configuration > Pool Area Configuration
configure > context context_name > mme-service service_name > pool-area pool_area_name type hash-value
Entering the above command sequence results in the following prompt:
[context_name]host_name(config-mme-pool-area-hash-value)#
hash-value { hash_value | range start_value to end_value } use-msc msc_name
no hash-value { hash_value | range start_value to end_value }
Removes the configured hash value for this pool area.
Specifies the specific hash value for this pool area.
hash_value must be an integer from 0 through 999.
Specifies the range of hash values for this pool area.
start_value specifies the start value for range of hash and is an integer value from 0 through 999.
end_value specifies the end value for range of hash and is an integer value from 0 through 999.
The start_value must be lower than the end_value .
Specifies the MSC to use when this pool area is selected.
msc_name is the name of the MSC as configured in the MME Service using the msc command; msc_name must be an alphanumeric string of 1 to 39 characters.
This command associates an MSC with this pool. It also assigns the MSC to use based on the hash value as computed from the IMSI digits [(IMSI div 10) modulo 1000].
A maximum of 24 hash values can be configured within each pool area.
If no matching MSC is found, the SRVCC handover fails.
The following command configures hash values from 111 to 222 to use the MSC named mscwest1 in this pool.
hash-value range 111 to 222 use-msc mscwest1
Associates a Public Land Mobile Network (PLMN) identifier with a Mobile Switching Center (MSC) pool area.
MME
Administrator
Exec > Global Configuration > Context Configuration > MME Service Configuration > Pool Area Configuration
configure > context context_name > mme-service service_name > pool-area pool_area_name type hash-value
or
configure > context context_name > mme-service service_name > pool-area pool_area_name type round-robin
Entering the above command sequences result in the following prompts, respectively:
[context_name]host_name(config-mme-pool-area-hash-value)#
[context_name]host_name(config-mme-pool-area-round-robin)#
plmn-id mcc code mnc code
no plmn-id
Removes the configured plmn-id assigned to this MSC pool area.
Specifies the Mobile Country Code for this mobile access network. code must be a three-digit integer from 200 to 999.
Specifies the Mobile Network Code for this mobile access network. code must be a two- or three-digit integer from 00 to 999.
Use this command to associate a PLMN with an MSC pool area. This PLMN is used to select an MSC pool area based on the target PLMN as specified in the SRVCC handover request.
When configured, the MME attempts to select an MSC using the following selection order:
Pool area that matches the PLMN and of type hash.
Pool area that matches the PLMN and of type round-robin.
Pool area that does not have PLMN associated and of type hash.
Pool area that does not have PLMN associated and of type round-robin.
When this command is used, only one PLMN can be assigned per pool area of the same type (either hash-value or round-robin). A hash value pool area and a separate round robin pool area can be configured with the same PLMN. In this case, the hash value pool has the higher priority.
If no matching MSC is found, the SRVCC handover fails.
The following command identifies the mobile network with MCC of 123 and MNC of 12 .
plmn-id mcc 123 mnc 12
Associates a Mobile Switching Center (MSC) with the pool area.
MME
Administrator
Exec > Global Configuration > Context Configuration > MME Service Configuration > Pool Area Configuration
configure > context conext_name > mme-service service_name > pool-area pool_area_name type round-robin
Entering the above command sequence results in the following prompt:
[context_name]host_name(config-mme-pool-area-round-robin)#
[ no ] use-msc msc_name
Removes the associated MSC name from this pool area.
Associates an MSC name with this pool area.
msc_name is the name of the MSC as configured in the MME Service using the msc command. msc_name must be an alphanumeric string of 1 to 39 characters.
This command associates an MSC with this pool area. With a round-robin pool area selection, the MME selects the next MSC within the pool based on a round-robin scheme.
A maximum of 24 MSC associations can be defined within each round-robin pool area.
The following command associates the MSC named mscsouth1 to this pool.
use-msc mscsouth1
