Method and apparatus for initiating communication sessions

摘要

An aspect of the subject disclosure may include, for example, receiving a request from a communication device to initiate a communication session in a packet-switched network, obtaining a first name authority pointer record responsive to determining that there is an undesirable operational state in the packet-switched network, wherein the first name authority pointer record comprises a null record, obtaining a second name authority pointer record responsive to determining that there is a desirable operational state in the packet-switched network, wherein the second name authority pointer record comprises a record, and initiating the communication session according to one of the first name authority pointer record or the second name authority pointer record. Other embodiments are disclosed.

1. A method, comprising:
receiving, by a system comprising a processor, a request from a communication device to initiate a communication session; obtaining, by the system, a first name authority pointer record comprising a null record responsive to determining that there is an undesirable fault level in a voice over long term evolution network, wherein the null record causes a network element processing the record to initiate the communication session utilizing a circuit-switched communication network; obtaining, by the system, a second name authority pointer record responsive to determining that there is no fault or a tolerable level of faults in the voice over long term evolution network, wherein the second name authority pointer record comprises a record for initiating the communication session utilizing the voice over long term evolution network; initiating, by the system, the communication session according to one of the first name authority pointer record or the second name authority pointer record obtained by the system; creating the first name authority pointer record from the second name authority record by deleting the record in the second name authority record thereby generating the first name authority pointer record with the null record responsive to determining that there is the undesirable fault level in the voice over long term evolution network; and restoring the second name authority pointer record from the first name authority record by adding the record in the first name authority record thereby generating the second name authority pointer record with the record responsive to determining that there is no fault or the tolerable level of faults in the voice over long term evolution network.
