摘要:
Systems and/or methods described herein may include an Internet Protocol (IP) Multimedia Subsystem (IMS) Session Initiation Protocol (SIP) optimization server in communication with network elements within an IMS network. The IMS SIP optimization server may facilitate an end-to-end SIP session between an originating user device and a terminating user device, while sending SIP session information to intermediate network elements in parallel. The IMS SIP optimization server may receive a SIP request from a first network element and send a related SIP request to a last network element. The IMS SIP optimization server may also send customized packet messages to any intermediate network elements, where the intermediate network elements are between the first network element and the last network element in the SIP sequence, and where the customized packet message includes SIP setup commands for each of the intermediate network elements.
摘要:
A network device forwards a Session Initiation Protocol (SIP) setup request from an originating user device toward a destination user device via multiple network elements and intercepts a message-too-large error message sent from one of the multiple network elements to the originating user device. The network device automatically splits the session setup request into smaller SIP messages, where a size of each of the smaller SIP messages is less than or equal to a particular size of message that the network element will accept. The network device then notifies another one of the multiple elements that the session setup request has been split into the smaller SIP messages and sends, via the multiple network elements, the smaller SIP messages toward the destination user device on behalf of the originating device.

A device receives a PDN connection request from a UE, and exchanges, with a HSS, authentication and authorization information associated with the UE. The device also constructs an APN FQDN based on the authentication and authorization information, and sends a query, that includes the APN FQDN, to a DNS server. The device further receives, from the DNS server, PGW FQDNs that contain the APN FQDN, and compares the PGW FQDNs with a FQDN associated with a SGW. The device determines, based on the comparison, a PGW, associated with a PGW FQDN that is a closest match to the FQDN associated with the SGW, to be a primary PGW for the PDN connection request. The device also determines, based on the comparison, one or more PGWs, residing within a predetermined distance of the SGW, to be one or more backup PGWs for the PDN connection request.

A device provides, to a domain name system (DNS), a request for candidate network nodes to which to connect, and receives, from the DNS and based on the request, a list of fully qualified domain names (FQDNs) for the candidate network nodes. The device truncates the FQDNs in the list of FQDNs to create a list of truncated FQDNs corresponding to the candidate network nodes, and stores the list of truncated FQDNs in a buffer associated with the device.

A first phone obtains an identifier of a second phone from a phone list, and sends a request for the second phone's Session Initiation Protocol (SIP) type to a remote server. The first phone receives the second phone's SIP type from the remote server, and sends a message to one or more nodes in a network, based on the received second phone's SIP type, for a SIP session between the first phone and the second phone.

A device receives code division multiple access (CDMA) capacity/resource information via a first direct interface with a radio network controller (RNC) associated with a CDMA radio access network (RAN), and determines, based on the CDMA capacity/resource information, a capacity associated with the CDMA RAN. The device also determines, based on the CDMA capacity/resource information, a resource availability associated with the CDMA RAN, and determines, based on the capacity and the resource availability associated with the CDMA RAN, a CDMA RAN resource allocation.

A system includes a first device, in a first network; a second device, in a second network; and a policy rules and charging function (PCRF) database that associates Internet Protocol (IP) addresses assigned to user equipment (UE) devices with PCRF devices; where the first device is to identify a plurality of policy rules and charging function (PCRF) devices in the first network, select a PCRF device from the plurality of PCRF devices based on a selection rule, and provide information about the selected PCRF device to the second device; and where the second device is to receive a request to set up a communication session associated with a UE device; determine an IP address associated with the UE device; identify a PCRF device, based on the determined IP address, by accessing the PCRF database, and send session information associated with the communication session to the identified PCRF device.
