Some example embodiments may generally relate to mobile or wireless telecommunication systems, such as Long Term Evolution (LTE) or fifth generation (5G) radio access technology or new radio (NR) access technology, or other communications systems. For example, certain example embodiments may relate to apparatuses, systems, and/or methods for preventing data outage for user equipment (UE) during Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) New Radio Dual Connectivity (EN-DC).
Examples of mobile or wireless telecommunication systems may include the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Long Term Evolution (LTE) Evolved UTRAN (E-UTRAN), LTE-Advanced (LTE-A), MulteFire, LTE-A Pro, and/or fifth generation (5G) radio access technology or new radio (NR) access technology. Fifth generation (5G) wireless systems refer to the next generation (NG) of radio systems and network architecture. 5G is mostly built on a new radio (NR), but the 5G (or NG) network can also build on E-UTRAN radio. It is estimated that NR will provide bitrates on the order of 10-20 Gbit/s or higher, and will support at least enhanced mobile broadband (eMBB) and ultra-reliable low-latency-communication (URLLC) as well as massive machine type communication (mMTC). NR is expected to deliver extreme broadband and ultra-robust, low latency connectivity and massive networking to support the Internet of Things (IoT). With IoT and machine-to-machine (M2M) communication becoming more widespread, there will be a growing need for networks that meet the needs of lower power, low data rate, and long battery life. It is noted that, in 5G, the nodes that can provide radio access functionality to a user equipment (i.e., similar to Node B in UTRAN or eNB in LTE) are named gNB when built on NR radio and named NG-eNB when built on E-UTRAN radio.

For proper understanding of example embodiments, reference should be made to the accompanying drawings, wherein:
It will be readily understood that the components of certain example embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. The following is a detailed description of some example embodiments of systems, methods, apparatuses, and computer program products for preventing data outage for user equipment (UE) during Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) New Radio Dual Connectivity (EN-DC).
The features, structures, or characteristics of example embodiments described throughout this specification may be combined in any suitable manner in one or more example embodiments. For example, the usage of the phrases “certain embodiments,” “an example embodiment,” “some embodiments,” or other similar language, throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment. Thus, appearances of the phrases “in certain embodiments,” “an example embodiment,” “in some embodiments,” “in other embodiments,” or other similar language, throughout this specification do not necessarily refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments. Additionally, “MeNB” may be interchangeably used as “master node” or “master node/MeNB”, or individually used as “MeNB” and “master node”. “MeNB” may also have an equivalent meaning as “master node”. Further “en-gNB/SgNB” may be interchangeably used as “secondary node/en-gNB/SgNB”, or individually used as “secondary node”, “en-gNB” or “SgNB”. Additionally, “secondary node”, “en-gNB”, and SgNB may have an equivalent meaning. Furthermore, “S1-U” may be interchangeably used as “S1-U”, “NG-U”, or “S1-U/NG-U”, or individually used as “S1-U”, “NG-U”, or “S1-U/NG-U”. Each of “S1-U” and “NG-U” may also have an equivalent meaning.
In some cases, general packet radio service (GPRS) tunneling protocol for user plane (GTP-U) failure may arise due to switch/router upgradation, or intermediate hardware failure (switch/router) in an IP network, which sometimes need operator intervention to restore it back to stock. 3rd Generation Partnership Project (3GPP) describes GTP-U path failure handling at the access network and core network, respectively. For example, 3GPP describes, for path failure, a node detecting the GTP-U path failure with its peer may notify the upper layer of the path failure so that the user equipment (UE) can be disconnected from the network, and can retry the attach procedure. 3GPP also describes path failure in the serving gateway (SGW) and the mobility management entity (MME). For example, the SGW may detect the GTP-U path failure with its peer and notify the MME. The MME may in turn allocate another SGW for the bearer or release the bearer. Furthermore, the MME may derive the S1-U/NG-U path information (e.g., the eNB fully qualified tunnel endpoint identifier (F-TEID) and the SGW F-TEID) from the UE context, and mark it as failed. In addition, the MME may store such information for a configurable period. The MME may also avoid selecting the SGW with a failed S1-U/NG-U path towards the eNB for subsequent packet data network (PDN) connection establishment procedures and mobility procedures with SGW relocation.
According to certain example embodiments, when the GTP-U path failure is identified by the secondary node/en-gNB/SgNB, the status may be indicated to the master node/MeNB. Based on the received path status, the master node/MeNB may avoid the selection of such paths (e.g., en-gNB SGW pair) experiencing the path failure for a secondary gNodeB (SgNB) addition procedure. As such, the UE with dual connectivity capability may not have a secondary cell group (SCG) bearer established involving the path having the failure. Accordingly, it may be possible to avoid experiencing data outage due to the broken link.
In certain example embodiments, to indicate the status of the path failure, the secondary node/en-gNB/SgNB may adapt the existing “gNB Status Indication Message” to update the peer master node/MeNB. Alternatively, in other example embodiments, the secondary node/en-gNB/SgNB may introduce a new message to indicate the status to all the master nodes/MeNBs to which it has X2 setup successfully. According to certain example embodiments, by maintaining the status of the paths between the secondary node/en-gNB/SgNB and SGWs, the master node/MeNB can select an alternative secondary node/en-gNB/SgNB that does not have any connectivity issues with the SGW provided by the MME. According to other example embodiments, the master node/MeNB may request for a different SGW from the MME when there are no alternate secondary nodes/en-gNBs/SgNBs available.
In certain example embodiments, the master node/MeNB may receive the status of the paths from the secondary node/en-gNB/SgNB peers through various mechanisms. For example, in some example embodiments, the master node/MeNB may receive status of the paths from secondary node/en-gNB/SgNB peers via an adapted gNB status indication message. In other example embodiments, the master node/MeNB may receive status of the paths from secondary node/en-gNB/SgNB peers via a GTP-U status indication message, which may be a unicast message or a broadcast message.
According to certain example embodiments, the master node/MeNB may include S1-U/NG-U path status as an additional criteria while selecting a secondary node/en-gNB/SgNB so that the secondary node/en-gNB/SgNB selected for SCG bearer may not cause data outage at the UE (see
Table 2 lists certain examples of the S1-U/NG-U path information. According to certain example embodiments, this information element (IE) may provide information on the S1-U/NG-U supervision status. Further, Table 3 lists certain examples of the S1-U/NG- U interface events. According to certain example embodiments, the events upon which S1-U/NG-U path status may be communicated to the master node/MeNB may include those listed in Table 3. In addition, Table 4 lists certain examples of GTP-U status indication information. According to certain example embodiments, the GTP-U status indication information may be sent as a message by the secondary node/en-gNB/SgNB to indicate to the eNB its status of S1-U/NG-U path.
In certain example embodiments, on occurrence of events (see Table 3) over the S1-U/NG-U interface, the secondary node/en-gNB/SgNB may send a gNB status indication message (see Table 1) including optional S1-U/NG-U path status information IE (see Table 2) to indicate the S1-U/NG-U path status. Alternatively, in other example embodiments, the S1-U/NG-U status information may be communicated via a new message GTP-U status indication message (see Table 4).
According to certain example embodiments, the method of
According to certain example embodiments, the status of the user plane path may include a failure status or recovered status. According to other example embodiments, the status may be transmitted to the second network node via a network node status indication message, a general packet radio service tunneling protocol for user plane (GTP-U) status indication message, or any other message between the first network node and the second network node. According to further example embodiments, the GTP-U status indication message may be a unicast message or a broadcast message.
In certain example embodiments, the network node status indication message may include GTP-U path status information along with overload information. In other example embodiments, the network node status indication message may include S1 user plane interface path status information to indicate an S1 user plane interface path status. In some example embodiments, the S1 user plane interface path status information may be communicated via a new GTP-U status indication message.
According to certain example embodiments, the method of
According to certain example embodiments, when it is determined that an alternate network node is not available, the method may also include requesting a mobility management entity for a different gateway node, or continuing a connection with a master cell group bearer path. According to other example embodiments, when it is determined that an alternative network node is available, the method may further include retrieving the status of the user plane path of the alternative network node. According to further example embodiments, the status may be retrieved via a network node status indication message, or a general packet radio service tunneling protocol for user plane (GTP-U) status indication message.
In certain example embodiments, the GTP-U status indication message may be a unicast message or a broadcast message. In some example embodiments, the network node status indication message may include GTP-U path status information along with overload information. In other example embodiments, the network node status indication message may include S1 user plane interface path status information to indicate an S1 user plane interface path status. In further example embodiments, the S1 user plane interface path status information is communicated via a new GTP-U status indication message.
