  • Patent number: 9907099
    Abstract: Embodiments herein relate to a method in a relay node for acquiring information about a type of a radio network connection between a donor radio base station and a radio base station. The relay node and the donor radio base station are comprised in a radio communications network and the donor radio base station is serving the relay node. The relay node receives a message from the donor radio base station, which message is indicating a type of radio network application protocol, which type is related to a type of the radio network connection between the donor radio base station and the radio base station. The relay node determines the type of the radio network connection based on the type of radio network application protocol indicated in the message. The relay node also stores the type of radio network connection in relation to the radio base station for selecting the type of radio network connection when later communicating with the radio base station.

  • Patent number: 9883378
    Abstract: Embodiments herein relate to a network node for handling a Radio Access Network, (RAN) context information of a wireless device in a cell served by the network node in a wireless communications network. The network node stores the RAN context information of the wireless device when the wireless device is no longer in a connected state in the cell. When the wireless device has returned to a connected state in the cell, the network node receives information indicating a RAN context information from the wireless device. Also, the network node transmits, to the wireless device, information indicating that the wireless device is to use the indicated RAN context information in the cell when the indicated RAN context information is such that it can be reused with the RAN context information of the wireless device previously stored by the network node. Embodiments of the network node are also described.

  • Publication number: 20180020394
    Abstract: A network node (600), a wireless device (602) and methods therein, for enabling access to a radio network. System signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area. The system signatures are reused in a second area as associated with system information configurations which are different than in the first area. The network node (600) indicates (6:3) that at least one system information configuration stored in the wireless device (602) is invalid and should not be used. The wireless device (602) then makes (6:4) the at least one invalid system information configuration unusable in the wireless device, e.g. by deleting it from the wireless device (602). Thereby, the risk of using an incorrect system information configuration based on a reused system signature can be reduced or eliminated.

  • Publication number: 20170374585
    Abstract: Embodiments herein relate e.g. to a method performed by a network node (15,13) for handling data of a wireless device (10) in a communication network (1). The network node (15,13) receives an indication from the wireless device (10), which indication indicates a presence of the wireless device at a second radio access network node (13) holding no context for the wireless device (10). The network node (15,13) identifies a first radio access network node (12) holding context for the wireless device (10) and any buffered data destined for the wireless device (10). The network node (15,13) retrieves from the identified first radio access network node (12), data buffered for the wireless device (10), and forwards the retrieved data to the wireless device (10).

  • Patent number: 9843921
    Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

  • Patent number: 9843996
    Abstract: A method and a wireless device for managing selection of a Wireless Local Area Network “WLAN” are disclosed. The wireless device obtains a first sub-set of WLAN identifiers, which first sub-set relates to user preference for selection of WLAN, and/or a second sub-set of WLANs, which second sub-set relates to WLAN Selection Policy. The wireless device receives, from the radio network node, a third sub-set of WLAN identifiers, which third sub-set relates to a list of WLANs, wherein each of the first and/or second sub-sets and the third sub-set is associated with a respective priority level for indicating which WLAN to prioritize over the other WLANs. The wireless device selects a WLAN from among the first, second and third sub-sets of WLAN identifiers based on the respective priority levels. The wireless device evaluates RAN rules in view of the selected WLAN, and connects to the selected WLAN when the RAN rules are fulfilled.

  • Publication number: 20170346659
    Abstract: Embodiments of the invention generally relate to address resolution in a wireless communication system. The access node may locally determine, responsive to receiving a second-layer network address associated with a destination communication device from a source communication device in the wireless communication system, a first-layer network address of the destination communication device from the second-layer network address. The access node may send, responsive to the first-layer network address being unavailable, a request for the first-layer network address to an address resolution server in the wireless communication system. In this way, the time and resources for address resolution may be saved, and the efficiency of the address resolution may be improved.

  • Patent number: 9826437
    Abstract: The invention relates to a method for relocating a first function for processing data packets of a flow associated with a device, from a source to a target instance. The method is triggered by an initiated relocation of a second function for processing data packets of the flow. The method comprises initiating (710) a first phase of a relocation method for relocating the first function, before the relocation of the second function is finalized. The method also comprises determining (720) whether to initiate a second phase of the relocation method based on information related to a progress of the relocation of the second function. When it is determined (720) to initiate the second phase, the method further comprises initiating (730) the second phase of the relocation method comprising the resumption of the processing of the data packets of the flow at the target instance of the first function.
