The present disclosure relates generally to call routing techniques, and more specifically to a method for selective routing to service call centers.
Toll-free service call center providers often have geographically dispersed service call centers to manage their service over a wide area such as a city, state, or nation. It is generally desirable that a service call center nearest to a calling party process incoming calls from said party. Today service call center providers route calls according to an automatic number identification (ANI) included in the incoming call. From the ANI, a caller ID can be identified which can be used to approximate the caller's location and thereby route the call to the nearest call center.
This location identification process, however, can be ineffective for mobile phone users. When a mobile phone user makes a call to a toll-free number there is no guarantee that the end user will be at a location associated with the caller ID. Accordingly, the caller may be routed to a service call center far from the location of the caller which would be undesirable.
A need therefore arises for a method to selectively route callers to service call centers.
Embodiments in accordance with the present disclosure provide a method for selectively routing callers to service call centers.
In a first embodiment of the present disclosure, a call management center (CMC) has a controller for managing operations of a plurality of network elements. The controller can be programmed to store for each of the plurality of network elements its location, store for each of a plurality of service call centers its location, detect an incoming call originated by a communication device from a select one of the plurality of network elements, and determine if the communication device is capable of roaming from signaling information associated with the incoming call. If the communication device is capable of roaming, the controller can be programmed to identify from the plurality of network elements according to the signaling information a network element near to where the incoming call was originated, determine an approximate location of the communication device according to a location of the identified network element, select a service call center nearest to the approximate location of the communication device from the plurality of service call center locations, and route the incoming call to the selected service call center.
In a second embodiment of the present disclosure, a computer-readable storage medium operates in a call management center (CMC). The storage medium can have computer instructions for determining if a communication device is capable of roaming from signaling information associated with the incoming call. If the communication device is capable of roaming, the storage medium can include computer instructions for determining an approximate location of the communication device according to a jurisdiction information parameter (JIP) included in the signaling information, selecting from the plurality of service call centers a service call center nearest to the communication device according to the identified service call center provider and the approximate location of the communication device, and routing the incoming call to the selected service call center.
In a third embodiment of the present disclosure, a method operates in a service control point (SCP). The method includes the steps of detecting an incoming call originated by a communication device from a select one of a plurality of network elements, and determining if the communication device is capable of roaming by detecting in a portion of an Originating Line Information Parameter (OLIP) included in signaling information associated with the incoming call any one of the numbers 61, 62 and 63. If the communication device is capable of roaming, the method can further include the steps of identifying from the plurality of network elements according to a jurisdiction information parameter (JIP) included in the signaling information a network element near to where the incoming call was originated, determining an approximate location of the communication device according to a location of the identified network element, selecting a service call center nearest to the approximate location of the communication device from a plurality of service call center locations, and routing the incoming call to the selected service call center.
The CMC 102 can be programmed to manage network elements 103 of the communication network 101. Accordingly, the CMC 102 can be represented by a service control point (SCP) in whole or in part that is capable of intercepting and routing incoming calls to any one of a number of service call centers 112. A network element 103 in the present context can mean a cellular base station or common local and/or long-distance network switches. From a combination of network elements 103 the communication network 101 can support a hybrid of cellular communications (e.g., CDMA, GSM, UMTS, TDMA, and so on) and wired PSTN (Public Switched Telephone Network) communications. For establishing and terminating calls, a number of the network elements 103 exchange signaling information with the CMC 102 in conformance with the well known Signaling System 7 (SS7) protocol.
Step 202 also allows each service call center provider to enable or disable network element 112 search services for roaming callers as will be described shortly. In step 204, the controller 104 can be further programmed to logically group and store in the database 106 the service call locations according to the associated service call center providers. In step 206, the controller 104 can be programmed to store locations for each of the network elements 103 of the communication network 101. The locations of the network elements 103 can similarly be stored in the database 106.
In step 208, the controller 104 monitors incoming calls from callers 108 or 110 coupled to the communication network 101 by way of the network elements 103. If an incoming call is detected, the controller 104 proceeds to step 210 where it identifies a service call center provider from the database 106 according to a calling number retrieved from a portion of an automatic number identification (ANI) included in SS7 signaling information received with the incoming call. This portion of the ANI can be represented by the NPA-NXX-XXXX (i.e., the 10 digit calling number). Step 208 and the steps that follow are executed by the controller 104 only if the provisioning information provided in step 202 calls for routing calls according to the JIP. Thus, in step 202 routing of calls according to the JIP can be enabled or disabled for each calling number (e.g., a toll-free number) associated with the service call centers 112. The process for enabling or disabling JIP routing for each of the calling numbers can be accomplished by checking off or toggling a button presented by a graphical user interface (GUI) of the website.
In step 212, the controller 104 further determines if the communication device originating the incoming call is capable of roaming. This information can be determined from an Originating Line Information Parameter (OLIP) included in the SS7. The OLIP is also referred to as an ANI II code which has two digits ranging from 00 through 99. If the ANI II digits are 61 (PCS Type 1), 62 (PCS Type 2) or 63 (PCS roaming), the controller 104 can determine therefrom that the incoming call originated from a mobile communication device such as communication device 110 illustrated in
Accordingly, when the controller 104 detects a roaming communication device 110, it proceeds to step 214 where it identifies a network element 103 near to where the incoming call was originated from a portion of the signaling information referred to as JIP. The JIP provides an NPA-NXX that identifies the network element 103 nearest to a location where the incoming call originated. The network element 103 identified can be a switch closest to the base station receiving the incoming call. Once the network element 103 has been identified, the controller 104 proceeds to step 216 where it determines an approximate location of the communication device 110 from a location of the network element 103 as identified in a local exchange routing guide (LERG).
The approximate location of the communication device 110 may be a geographic footprint associated with the identified network element 103. From step 216, the controller 104 proceeds to step 222 where it selects a call center 112 from its database 106 nearest to the communication device 110 according to the identified service call center provider and the approximate location of the communication device 110. Thus, the controller 104 attempts to match the geographic footprint of the communication device 110 (derived from the footprint of the network element 103) to the nearest geographic footprint of the service call centers 112. Once the nearest service call center 112 has been identified, the controller 104 proceeds to step 224 where it routes the incoming call to the selected service call center 112.
The foregoing steps occur prior to any interaction with the service call centers 112. That is, the first interaction between a service call center 112 and the calling party associated with the incoming call takes place at the nearest point between the parties. Accordingly, there is no need for an agent or automated controller in a service call center 112 intercepting the call to route the call to another service call center because another service call center is found to be closer to the calling party. The agent may reroute the call to another service call center for reasons unrelated to proximity such as, for example, routing the caller to another center 112 having a particular expertise unavailable in her center to best serve the caller's needs.
Referring back to step 212, if the controller 104 detects that the incoming call is not associated with a roaming communication device (such as a residential communication device 108 shown in
The aforementioned descriptions of method 300 provides for a single step routing transaction to a service call center 112 nearest to the communication device 108 or 110 originating the call. Method 300 can be applied to any number of service call center transactions. For example, method 300 can be used for present and future generations of toll-free service calls, information service calls (e.g., 411 and XXX-555-1212 calls), emergency service calls, and billable service calls (e.g., 900-XXX-XXXX).
